    Abstract [en]

    One of the park and street workers many tools, is the traditional broom. The

    broom is used to tidy up surfaces where machines can’t reach, such as; underneath

    benches, in corners and smaller areas. Using a traditional broom requires a twisted

    and forward leaning body posture that, if performed during an extended time

    period, can result in musculoskeletal problems and negative impact on the health.

    This project aimed to develop a new cleaning tool to reduce the forward-leaning,

    twisted body posture.

    This thesis used a product development methodology and a biomechanical

    analysis to fulfil, and evidence base the aim. Review of the literature,

    biomechanical analysis and benchmarking were used to set requirement

    specifications for this project. The project applied David G Ullman's iterative

    product development methodology, including brainstorming, quality function

    deployment, morphology, Pugh´s matrix and a failure mode effects analysis.

    Furthermore, a functional prototype was built as a last step of the development

    phase.

    Evaluation of the prototype, in comparison to the traditional broom, was

    performed using 3D movement analysis (Qualisys motion capture system) and

    surface electromyography (Mega 8 channel system) on one test person.

    The project resulted in a physically functional prototype that can be used for

    similar tasks as a traditional broom. The concept design dictates the user to push

    the cleaning tool in front of the body with postural symmetry in all three planes.

    The comparison between a traditional broom and the prototype showed a

    reduction in muscle activity when using the prototype. Furthermore, the

    movement analysis showed a working posture with less forward leaning and back

    rotation. Furthermore, the participant could keep neutral angles in the shoulders

    and wrists throughout the task. Note that, the biomechanical analyzes was only

    made on one test person which is not enough to conclude that the prototype

    contributes to a more healthy working posture.

    AN OPEN INNOVATION APPROACH TO THE RADICAL INNOVATION PROCESS: An Analysis of the Management of the Process of Radical Innovation in an Open Innovation Paradigm2010Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis amends some existing theoretical gaps and an overall lack of empirical studies regarding the ways R&D managers can use Open Innovation during the management of the radical innovation processes’ early development phase.Using existing theories, an interview guide and an analytical model was created. These were later used during the gathering and analysis of empirical data. Our sampling involves three of Sweden’s largest companies, representing three distinct industry fields. Interviews took place during April 2010, and all the interviewees were R&D managers with previous experience with Open Innovation and radical innovation.The results reveal that the managers do use Open Innovation when managing radical innovation, and point to both benefits and issues brought about by using Open Innovation during this process. The use of Open Innovation during the management of radical innovation can be divided into two main aspects; the actual extent to which it is used, and the ways the managers use it. Our results reveal that the extent varies from an early peak, an in between Open Innovation chasm and a final increase. Furthermore, our studies also show that the main ways the managers use OI are; exploitation and creation of revenue streams, knowledge leveraging and integration, and finally to create superior products using broad knowledge networks.

    Sustained innovativeness and human resource management2011In: Research on Technology, Innovation and Marketing Management 2009-2011: Introducing the Research Area of Innovation Science / [ed] Sven-Åke Hörte, Halmstad: Högskolan i Halmstad , 2011, p. 21-35Chapter in book (Other academic)
    Abstract [en]

    Innovation is paramount to success. Over time firms must maintain their ability to innovate in order to maintain their competitive edge. In this paper we explore the role human resource management has in nurturing and enhancing the innovative capability of the firm. To explore HRM activities, functions and processes that enhance or impede innovativeness we conducted a literature review. Following this review, 10 propositions have been made that link HRM to both incremental and radical innovativeness respectively. Our results include suggestions for empirical studies to validate our propositions as well as some managerial implications.

    Förbättrad manövrering av lastvagn2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis has been made on behalf of, and in cooperation with Getinge Sterilization. The purpose of this project has been to develop a solution that makes trolleys of the SMART-trolley series more maneuverable when users are now experiencing them as difficult to maneuver. The handle and the trolleys wheel configuration were identified as the main factors influencing the trolleys maneuverability. Efforts were therefore set up to develop a new handle and a new wheel configuration that solves the maneuvering problem. Along with Getinge a specification of requirements and requests for the new solution was made.

    Initially principle solutions as simple sketches, on possible solutions solving the problem were developed. This was made without taking into account of anyrequirements or requests. Principle solutions are then evaluated against the requirements where the solutions who do not meet the requirements were screened away.

    Handle solutions that made it from the evaluation were presented to Getinge, who selected one of the solutions to develop a prototype from. Therefore, no further evaluations of the handle solutions were made. The selected handle solution underwent primary design process and further develops to best meet requirementsand to be manufacturable in a bending machine. A prototype of the final solution was manufactured.

    Principle solutions for wheel configurations underwent further evaluation, this time against the requests. Wheel configuration solutions that made it from the last evaluation, test prototypes were made and a user test was carried out to obtain a final solution. The result of this thesis is a trolley with an extra wheel pair and a new smaller handle to satisfy the projects purpose.

    Man måste gilla det, annars blir det tufft- en studie om mellanchefers psykosociala arbetsmiljö2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna studie var att undersöka mellanchefers upplevelser av den psykosociala arbetsmiljön. Studien baserades på fem utvalda respondenter, där kriteriet var att de befann sig på en mellanposition, med rapporteringsskyldighet både uppåt och nedåt inom organisationen. Insamlingen av data utgick från semistrukturerade intervjuer, och analyserades genom innehållsanalys. Resultatet tyder på att upplevelsen av tydligheten på kraven som ställs, det stora beslutsutrymme och det höga stödet från samtliga parter i organisationen gör att mellancheferna i denna studie upplever den psykosociala arbetsmiljön i organisationen som god. Trots stressigare perioder upplever de att ovan nämnda faktorer reducerar risken för skadlig stress. Till skillnad från tidigare forskning visade analysen av resultatet i vår studie att rollen som mellanchef inte behöver leda till skadlig stress. Slutligen diskuteras studiens arbetsvetenskapliga bidrag och förslag till framtida forskning. 

    Nyckelord: kontroll, krav, mellanchef, psykosocial arbetsmiljö, stöd.

    Effektivisering och förbättring av produktionslinje2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The thesis is done at Kvibille dairy and includes the design of a packing line for blue cheese.

    Today ́s line has a maximum production capacity of two tons per day, based on the fact that there are three employees at the line. The production includes three separateflavors to be packaged. The line has a high degree of manual labor and is considereddifficult to handle and not very ergonomic according to the staff on the production line. The goal for this thesis is to improve the ergonomic aspects of the line and if possible reduce the need for personnel without adventuring the production capacity.

    To find what improvements can be made on the line, a preliminary and background study was made. These studies include interviews, observations in the form of a Rapid Plant Assessment, time measurements and simulations. The study showed that the personnel felt some stress during the line and that the flow stops at several stations which impede the flow. The advantage is that the line is flexible and all the stationsin the line are oriented in the right order.

    After all the facts were collected and it was determined what was needed for the line, the search for suppliers began. What was needed was an adjustable table and fatigue mats to improve working conditions. Automation was also investigated to minimize the stress on the staff. The automation idea was later replaced with manually controlled aids and semi-automatic machines because it was considered more cost effective. To streamline the line, automatic scales with label applicators wereinvestigated and alternative packaging methods. These methods involved replacing the material on the foil so that the need for plastic wrapping is eliminated.

    The result was to replace the tables for height adjustable workbenches and introduce a vacuum lift to improve ergonomics on the line. The aluminum foil is replaced by a more durable wax laminated foil called DanaPhane with an integrated name label in the foil, eliminating the need for plastic foil and separate labels. Because the need for these is eliminated, environmental impact is minimized in terms of material utilization and transports. The elimination also means fewer operations, which reduces the need for additional staff. To further streamline the production, an automated scale and weight labeling for each cheese was introduced.

    Surface design methodology: challenge the steel2013In: Metrology and Properties of Engineering Surfaces, 2013: Proceedings of the 14th International Conference, Taipei, Taiwan, June 17-21, 2013, Bristol, UK: Institute of Physics Publishing (IOPP), 2013, p. 192-199Conference paper (Refereed)
    Abstract [en]

    The way a product or material is experienced by its user could be different depending on the scenario. It is also well known that different materials and surfaces are used for different purposes. When optimizing materials and surface roughness for a certain something with the intention to improve a product, it is important to obtain not only the physical requirements, but also the user experience and expectations. Laws and requirements of the materials and the surface function, but also the conservative way of thinking about materials and colours characterize the design of medical equipment. The purpose of this paper is to link the technical- and customer requirements of current materials and surface textures in medical environments. By focusing on parts of the theory of Kansei Engineering, improvements of the companys' products are possible. The idea is to find correlations between desired experience or «feeling» for a product, -customer requirements, functional requirements, and product geometrical properties -design parameters, to be implemented on new improved products. To be able to find new materials with the same (or better) technical requirements but a higher level of user stimulation, the current material (stainless steel) and its surface (brushed textures) was used as a reference. The usage of focus groups of experts at the manufacturer lead to a selection of twelve possible new materials for investigation in the project. In collaboration with the topical company for this project, three new materials that fulfil the requirements -easy to clean and anti-bacterial came to be in focus for further investigation in regard to a new design of a washer-disinfector for medical equipment using the Kansei based Clean ability approach CAA. © Published under licence by IOP Publishing Ltd.

    Whistleblowing- "En livlina att grabba tag i": En studie om rapportörers möjligheter att rapportera2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Whistleblowing är en möjlighet för en person att anonymt rapportera om en oegentlighet som förekommer inom organisationen. Studien har undersökt organisatoriska faktorer som påverkar denna möjlighet för den anställda, där fokus legat på vilka effekter rapporteringsstrukturen och organisationskulturen har för möjligheterna att rapportera. Undersökningen har utgått från en kvalitativ metod där intervjuer med fackliga företrädare har genomförts. Undersökning visade att det viktiga för att en whistleblowing-funktion ska ha en fungerande rapporteringsstruktur var kunskap om att funktionen finns, annars är det svårt att förvänta sig att få in rapporter. Vidare är det viktigt med tydliga rapporteringskanaler och riktlinjer där det framgår vad som är angeläget att rapportera om. Gällande organisationskulturen så var vikten av ett bra ledarskap det som framträdde tydligast. Har man ett ledarskap som tillåter en öppen kultur med högt i tak så skulle man inte vara i behov av funktionen i samma grad som om det vore lågt i tak. Är situationen sådan att man har anställda som använder sig av funktionen är det viktigt att man skapar en kultur där man som chef ser rapportörens handling som en förbättringsmöjlighet och därmed inte tilltar repressalier eller efterforska rapportören. Överlag var inställningen till funktionen att det vara bra att den fanns som ett alternativ, men att det primära borde vara att sträva mot en kultur där man kan ha dialoger på arbetsplatsen.

    Ställtidsreducering: Med hjälp av SMED2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose of this project was to reduce setup time on a press machine at Nitator Hylte AB and to develop a Standard Operating Procedure (SOP), which will serve as a basis for the operators to carry out the work. When the company was contacted so considered site manager that the current change over time was far from optimal and had the desire that it would be reduced by 50%. In connection with the project they were made some boundaries to make the project possible.

    The methodology that the authors have followed was Shigeo Shingo theory, Single Minute Exchange of Die (SMED), which assumes that it will change the routine during transitions by making as much preparation work as possible, this is done by analyzes based on observation from observations, videotaping and timings. The resistance that can occur when trying to reduce setup time is the human aspect, this type of resistors most often occurs in the lack of education and lack of good communication.

    The results from the project led to a new routine for how the work should be executed during the changeover. During the project diffrent kind of technical solutions was created to simplify the work during the changeover. At the end of the project the aouthers conducted a pilottest to determinate how much time that had been reduced. The Results from the test showed that 50 % of the time had been reduced.

    Produktionsutveckling av bastuaggregatsavdelning2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    To invent an optimized product is a complicated process. This process is only half of the work. It is equally important to develop a production system that can produce the product in an  efficient and ergonomic way.

    After several evaluations of conceptual and detailed drawings a final idea has come to light.The idea intends, to the maximum extent, utilize the facility in a more efficient way through moving assembly lines and stations closer to the flock section and the stock for complete products. To make the production better, stations are placed in more logical places given the assignment they are supposed to accomplish. This improves the material flow radically. An important aspect of the improvement is that the three assembly lines no longer will be dependent of each other because they will have all the stations they need.

    The final drawing uses the facility more efficiently. This opens up a big area close to the steam section. This area can be used to increase the productivity for the section. At present time the steam section have a capacity of around 9,000 units annually.

    Roughness variations in cylinder liners induced by honing tools’ wear2015In: Precision engineering, ISSN 0141-6359, E-ISSN 1873-2372, Vol. 41, p. 40-46Article in journal (Refereed)
    Abstract [en]

    The manufacturing and finishing (honing) of cylinder liners for the automotive industry is a constant challenge in order to reduce friction losses and oil consumption. A better knowledge of surfaces generated during plateau honing is then required for optimization of the process. Despite a well-known and controlled honing process, variations in surface roughness appear due to honing tool wear and need to be mapped and analyzed. The following paper proposes to map the variations in roughness by using confocal 3D measuring equipment able to inspect any area of a cylinder liner. Six motor blocks, each with five cylinder liners, were evaluated with 20 topography measurements per liner (giving six hundred 3D measurements in total). In addition to standard 3D roughness parameters, tailor made parameters extracting honing texture information are computed. The results show that only a few parameters (Spk, Ssc and Sk) do correlate with the honing tool wear specific to each cylinder. Tailor made parameters indicate similar results. Indeed, as the honing tool wears down, the cylinder liner surface gets rougher plateau or peaks and sharper asperities indicating that ploughing occurs instead of cutting. In future, experimental models could be built in order to perform production and functional optimizations. © 2015 Elsevier Inc. All rights reserved.

    Influence of Minimum Quantity Lubrication on Friction Characterizing Tool–Aluminum Alloy Contact2016In: Journal of tribology, ISSN 0742-4787, E-ISSN 1528-8897, Vol. 138, no 2, article id 021107Article in journal (Refereed)
    Abstract [en]

    The possibility to reduce the amount of cutting fluids from machining processes is actively studied by the industrials and researchers. Minimum Quantity Lubrication (MQL) is a solution towards cutting fluids reduction. This article investigates the consequences on friction coefficient induced by the use of MQL. A tribometer is used in order to simulate experimentally the tribological conditions encountered during machining. As the cutting speed increases a lower amount of oil is deposited on the rough surfaces. Depending on the MQL operating conditions and sliding velocities it is plausible to reach starvation by leaving the real rough contact partly dry. A model computing a starvation percentage by filling an estimated oil amount in a deformed topography correlates with the experimental results. © 2015 by ASME

    Simulation and Optimization of CNC controlled grinding processes: Analysis and simulation of automated robot finshing process2016Independent thesis Advanced level (degree of Master (One Year)), 40 credits / 60 HE creditsStudent thesis
    Abstract [en]

    Products with complicated shapes require superior surface finish to perform the intended function. Despite significant developments in technology, finishing operations are still performed semi automatically/manually, relying on the skills of the machinist. The pressure to produce products at the best quality in the shortest lead time has made it highly inconvenient to depend on traditional methods. Thus, there is a rising need for automation which has become a resource to remain competitive in the manufacturing industry.

    Diminishing return of trading quality over time in finishing operations signifies the importance of having a pre-determined trajectory (tool path) that produces an optimum surface in the least possible machining time. Tool path optimization for finishing process considering tool kinematics is of relatively low importance in the present scenario. The available automation in grinding processes encompass around the dynamics of machining.

    In this paper we provide an overview of optimizing the tool path using evolutionary algorithms, considering the significance of process dynamics and kinematics. Process efficiency of the generated tool movements are studied based on the evaluation of relative importance of the finishing parameters. Surface quality is analysed using MATLAB and optimization is performed on account of peak to valley height.

    Surface removal characteristics are analysed based on process variables that have the most likely impact on surface finish. The research results indicated that tool path is the most significant parameter determining the surface quality of a finishing operation. The inter-dependency of parameters were also studied using Taguchi design of experiments. Possible combinations of various tool paths and tool influencing parameters are presented to realize a surface that exhibits lowest errors.

    Effective Information Flow in the Internal Supply Chain: Results from a snowball method to map information flows2009In: Journal of Information & Knowledge Management, ISSN 0219-6492, E-ISSN 1793-6926, Vol. 8, no 4, p. 331-343Article in journal (Refereed)
    Abstract [en]

    Information sharing is an important factor for effectiveness within the internal supply chain. In this paper we use a methodology for mapping information flows in an internal supply chain, and case studies in two Swedish multinational organizations. Eight retrospective cases were used to map, describe and analyze the information flow that supports the physical material flow from the receipt of an order to point of delivery. Every involved person was interviewed on at least one occasion each. The interviews were conducted to map and describe the information and physical material flow. The aim was to identify factors that could improve and rationalise information flows and generate a better flow within the organization.

    The study shows the importance of an integrated information system, but also clearly indicates the importance of a collaborative culture and an awareness of the human-technology interface. The study also shows that three factors of interface distortions are most frequent in the cases: (1) changes registered in the database trigger no action among the staff, (2) new knowledge to staff is stored only orally and not in the database, and (3) interface between the paper system and the database, and between the old and the new information storage culture.

    Reduced engine friction for low climate impact2014Conference paper (Refereed)
    Abstract [en]

    Reducing friction in the Piston-Cylinder Unit - PCU is one of the priorities in the automotive industry as it is the largest contributor to the frictional losses and hence the fuel consumption of the internal combustion engines. Not only fuel consumption, but also the oil consumption and emissions are largely affected by the piston-ring-liner interactions. Therefore, from an optimized PCU, competitive, economic and environmental benefits would be gained.  In this project, fuel/oil consumption and emissions of car and truck engines were reduced by using different cylinder liner finishes and different ring designs/loads. Experimental and theoretical studies have been performed by simulating and testing the behaviour of various oil control rings and cylinder liner surfaces in reciprocating tribotesters. Several full-scale engine tests were performed to verify the improvements. The engine tests showed up to 1.8% reduction of the fuel consumption while keeping low oil consumption by using smoothly honed liner surfaces and low ring loads/widths. Further reduction of the oil consumption was shown in the tribotests and simulations when textured liner surfaces were used. To accomplish this, a cost-effective texturing process has to be found and to be confirmed in the engine tests.

    Characterisation of worn cylinder liner surfaces by segmentation of honing and wear scratches2011In: Wear, ISSN 0043-1648, E-ISSN 1873-2577, Vol. 271, p. 548-552Article in journal (Refereed)
    Abstract [en]

    The presence of the honing scratches/grooves in cylinder liner surfaces is intended and desired as they improve the lubrication and retain the debris reducing the piston assembly/liner friction and consequently improve the fuel economy and longevity of the internal combustion (IC) engines. Axial scratches caused by the abrasive wear between the tribological partners and/or entrained wear particles are undesired since they are correlated with increased oil consumption and noxious emissions of the IC engines. Due to the imperfection of the manufacturing process, the honing grooves, especially the deep ones, are smeared and interrupted by folds. A portion of the folds would eventually detach during the running process and act as abrasive particles increasing the wear in the cylinder. To closely examine the influence of all these features on the liner's function, it emerges a need to objectively quantify the axial wear scratches, plateau honing grooves, deep honing grooves and their interrupts. The existing techniques fail to segment a groove containing interrupts as they usually appear as summits at several locations in the course of the groove. Combining the profile and image analyses, the deep grooves and their interrupts were successfully identified and quantified in earlier works of the authors. In this paper those algorithms are extended, so that the deep honing grooves, plateau honing grooves and axial scratches crossing different depth levels are sequentially segmented in three levels/steps in an immersing way. A number of parameters derived from this method were utilised to compare 3D interference measurements from the top dead centre, middle and bottom region of a liner run in a truck engine test whereas the three regions represent different wear regimes due to the different running conditions. The results show that: (i) the axial scratches are densest in the top dead centre and about the same size as the plateau grooves in all three regions, while in the bottom region there are only few scratches; (ii) the presence of plateau grooves in the top region clearly decreases, (iii) the deep groove interrupt and coverage are lowest in the top region, and (iv) the groove height and distance between grooves spread mostly.

    Characterisation of Cylinder Liner Honing Textures for Production Control2013In: Characterisation of Areal Surface Texture / [ed] Richard Leech, Berlin: Springer Berlin/Heidelberg, 2013, p. 281-302Chapter in book (Refereed)
    Abstract [en]

    It is of common interest to reduce oil consumption and frictional losses in internal combustion engines, which are heavily influenced by the quality of the cylinder liner surface. The plateau cross-hatch topography of a cylinder liner consists of a system of grooves of different density, width and depth, some parts covered by folded metal, and some parts totally interrupted and unbalanced as a result of imperfection in the honing process. These grooves are critical for good liner function, and need to be quickly and objectively quantified for an efficient surface finish development. A suitable way to do this is to use 3D interference measurements and to combine profile and image analysis. Thus, the features/parameters, such as honing angle, balance of honing texture, groove interrupts, width, height, and distance between grooves, are successively quantified. Here, these parameters, along with areal surface texture parameters in the published ISO specification standard were used in two case studies. The first case study is on the effect of the folded metal on the surfaces of run truck liners and the second is an evaluation of the improvements of the surface quality introduced by the diamond honing in production of car liners. In addition, based on the significant parameters of the surface, a general characterisation tool for qualifying the surface quality and determination of the required number of measurements is presented. © 2013 Springer-Verlag Berlin Heidelberg.

    Zilent Ocean: EL-KONVERTERING AV INOMBORDSMOTORER TILL SEGELBÅTAR2009Independent thesis Basic level (university diploma), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Through extensive research it has shown that today’s sail boat owners are very frustrated concerning the limited choice of engine alternatives offered by today’s market. Besides rising fuel-costs, environmental awareness is very important in today’s society. Hence it is vital to find alternative environmental-friendly motors and replace combustion-engines.

     

    Zilent Ocean is an extensive project within Development engineering program at Halmstad University. The Project aims at minimizing environmental impact on our seas through limiting the usage of combustion-engines in sail boats. Zilent Ocean’s major target is the development of a customer-oriented company offering electric conversion kits of combustion-engines to sail boats at very competitive market prices.

     

    The Project was carried out by converting the combustion-engine in a MAXI 77 sailing boat (7.7m length, 5 beds). The current diesel-engine installed in the boat was replaced with a new DC electrical engine together with the appropriate controller unit.

     

    The finished sail boat prototype will be evaluated under the summer of 2009. The sail boat contains unique solutions enabling a more cost-efficient system in comparison with today’s combustion-engines. The aim is to provide a complete electric conversion kit at a lower price than a new combustion-engine. Together with lower investment costs, minimal maintenance and running costs, electrical conversion from Zilent Ocean is bound to be the future, and the natural decision for many sailors in Scandinavia.

    FRP i brokonstruktion: -varför används FRP inte i Sverige2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    FRP stands for Fiber Reinforced Polymer. FRP materials have yet to be introduced inbridge construction in Sweden. Composite materials can through combined componentsand manufacturing processes be tailored to fit advanced bridge designs. FRP materials arestrong, durable and of low weight. FRP materials give the superstructure reduced weightand are therefore a suitable alternative for industrial prefabrication. This report shows thatFRP materials are possible to use in bridge construction. With the introduction of a specificEurocode we are confident that FRP materials will become a competitive alternative inbridge construction in Sweden in the future.

    Abstract [en]

    Youth unemployment is currently a major problem in Europe. Young people have a harder time getting a full time job than 20 years ago. In cooperation with Arbetsförmedlingen (the Employment Service) Swedbank started the project Unga Jobb in order to get more young job- seekers into the labor market.

    The purpose of the study was with a qualitative method to get a better understanding of the iniative Unga Jobb and what collaboration means for the main stakeholders Arbetsförmedlingen (the Employment Service) and Swedbank. The purpose was also to study and analyze how Arbetsförmedlingen (the Employment Service), Swedbank and the community can take advantage of positive impacts of the project and how negative impacts of the project can provide lessons and be avoided.

    The study was conducted as a qualitative case study. The survey consisted of eight interviews with respondents from Arbetsförmedlingen and Swedbank.

    The main conclusion we can draw from the study is that the corporation is positive and needed to resolve difficult issues such as youth unemployment. It is important to work for better and more effective action and find solutions that are good for all parties, namely the community, organizations and individuals.

    60GHz Vital Sign Radar using 3D-printed Lens2016In: 2016 IEEE SENSORS, Piscataway: IEEE, 2016, article id 7808774Conference paper (Refereed)
    Abstract [en]

    There is an increased interest in contact-less vital sign monitoring methods as they offer higher flexibility to the individual being observed. Recent industrial development enabled radar functionality to be packed in single-chip solutions, decreasing application complexity and speeding up designs. Within this paper, a vital sign radar has been developed utilizing a recently released 60GHz frequency modulated continuous wave single-chip radar in combination with 3D-printed quasi-optics. The electronics development has been focused on compactness and high system integration using a low cost design process. The final experiments prove that the radar is capable of tracking human respiration rate and heartbeat at the same time from a distance of 1m.

    From Preliminary Ideas to Corroborated Product Definitions: Managing the Front End of New Product Development2012In: California Management Review, ISSN 0008-1256, E-ISSN 2162-8564, Vol. 54, no 4, p. 20-43Article in journal (Refereed)
    Abstract [en]

    Front-end activities largely influence the outcomes of new product development processes, because it is here that firms create new ideas, give them direction, and set them in motion. We show that the front end can be understood as comprising three core activities: idea/concept development, idea/concept alignment, and idea/concept legitimization, which allow firms to create corroborated product definitions. The paper provides important implications for managers interested in front-end management, and devote specific attention to the differences between incremental and radical front end development and to the front end in the light of increasingly open innovation processes.

    Survival Through Business Model Innovation: A Longitudinal Case Study from the Process Industries2014Conference paper (Refereed)
    Abstract [en]

    It is widely acknowledged that the design and quality of the business model is a main building block in what constitute a successful company. In this paper, we approach the critical question of how firms can successfully renew their business models over time. The aim is to identify the main sequences of events that precede business model innovation and which trigger evolutionary changes in how a firm develops and capture value. Theoretically, we approach business model innovation as an evolutionary phenomenon by emphasizing the dynamic and path dependent aspects of strategic change processes. Empirically, we employ a historical case study where we make an in-depth analysis of a firm in the process industry that has managed to innovate its business model several times since its inception. In all, the study identifies five main sequences of events related to customer value proposition, strategic investments, corporate identity, corporate structure, and value networks.

    Characterization of surface topography of a newly developed metrological gloss scale2015In: Surface Topography: Metrology and Properties, ISSN 2051-672X, Vol. 3, no 4, article id 045001Article in journal (Refereed)
    Abstract [en]

    In the European Joint Research Project 'Multidimensional Reflectometry for Industry', a new gloss scale was developed with the aim to represent different levels of gloss, hue, roughness, and refractive indices. In this paper, the surfaces of six selected samples were thoroughly investigated using various measuring techniques in order to verify the outcome of the novel manufacturing processes in terms of distinct levels as well as types of surface roughness. The aim of the evaluation was to capture surface structures in different wavelength intervals utilizing a confocal microscope, a coherence scanning interferometer, and an atomic force microscope. Power spectral density functions were also calculated from the measurements and used to determine suitability of techniques for different roughness scales. The measurements show that the expected surface characteristics as well as different RMS roughness values are intimately connected to the perceived glossiness.

    Abstract [en]

    The new product development (NPD) process is frequently described as a sequence of information processing activities, but "information in NPD" occupies a broader conceptual space than the reduction of uncertainty. This article reviews the area of "information in NPD" by examining the literature on environmental scanning, market orientation, gatekeepers, cross-functional integration, and information use. It is argued that we can understand the process of managing information in terms of three steps: Acquiring, sharing and using. A tentative framework for this area is proposed, and managerial implications resulting from this literature review and tentative frame are outlined and presented.

    The vision of this thesis was to create a concept that can be used as a base for amachine construction. The purpose of this project was to use different methods todevelop a concept that on the best way meets the sat up requirements. This projecthas been divided into three stages/parts; principle, primary and the final solutionstage.This thesis has been conducted in collaboration with Västkustägg AB. It is aconstruction project designed to construct a machine that will automatically putlabels on the egg packages. Västkust AB wanted to automate this process. Thecompany has only tested this process earlier by an operator who did this jobmanually.We came up with different solution during this project. The assessments of theseconcepts were made after Olsson's (1995) method and together with Terje Olsson- our supervisor at the company, later during the project. During the last stage ofthis project we chose to go with one final concept for a further developing. Alldemands made by the company were followed throughout the working process.We managed to develop a machine containing few and simple components, whichat the same time are very functional for its purpose. The design of our machine isdifferent from other industrial machines and labeling machines which makes itunique in its own way. This machine is meant for labels of two standard types ofpaper A5 and A6.The calculations we made during this project have been done in Catia V5 and hasbeen verified. We had a clear image of how our ideas should be in the beginningof this project and we knew how we wanted them to be we used our own theoriesand approaches in practice. Our theories and ideas showed in our sketches andprototypes. This along with other methods led to our final concept.We had also built some prototypes to be able to see if our ideas work in practice.The prototype led to some changes in our concepts. It gave us experience inprototype creating, functionality of the ideas and other areas.

    Vad påverkar mognadsgraden inför en implementering av SMED2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Globalization and growing competition are today placing increasing demands on organizations. To meet the tougher competition, it is common that companies implement various quality programs. These changes are seen as necessary measures in order to maintain market share and to be competitive. Introducing Lean tools and working on continuous improvement reduces the risk that production is shut down or moved to low-cost countries.

    In this thesis the authors have chosen to study one of these Lean tools used for setup time reduction. The tool is called SMED which stands for "Single Minute Exchange of Die" and aims to increase machine availability through more efficient tool change between different products. The thesis is a qualitative case study where the authors create an in-depth understanding of what it is that can affect the outcome. The key question that the authors seek to answer is: What influences the level of maturity before an implementation of SMED?

    Empirical data was collected through interviews and observations to answer the above problem. With the support of TQM (Total Quality Management), the authors have chosen to examine four areas and how they correlate to the outcome. The selected areas are referred to in this study as blocks and are: Implementation, Leadership, Competence and Corporate Culture. The correlation was performed using a regression analysis program Minitab. There the result shows that all four blocks influence, but have different effects on the outcome. The two most influential are Leadership and Corporate Culture that are responsible for a total of 84 %. A result that according to the authors met the survey's expectations and that could be confirmed by this study.

    The authors believe that this study can provide useful information and knowledge before implementation of SMED. As this thesis includes interviews and observations from ten companies.

    Abstract [en]

    This thesis has been done in cooperation with Lindab AB. The goal of the project is to create a tool wich aims to help the assembly of a ventilation silencer because it takes to much effort from the operators and is a non-ergonomic way of work.

    The construction method which will be used in this thesis is developed by Doctor Fredy Olsson in his thesis Systematical Construction at the instution of Mechanical Construction at Lunds Tekniska Högskola.

    The construction stages which is applied in this project are principle och primary construction. These stages will help the authors to generate a koncept of an assembly tool.

    The koncept has been adjusted several times after discussions with operators and supervisors to achieve the purpose of the project. These thoughts has been analysed and validated with intervies and FEM-analysis.

    The summary of the project is a developed koncept and support to complete the problem definition. With the limited amount of time and the need from Lindab to prioritize its resources elsewhere a final prototype was not able to be manufactured.

    Innovation-related Activities in a Low-tech Industry: A Study of the Electroplating and Surface Treatment Industry in Sweden2011In: Research on Technology, Innovation and Marketing Management 2009‐2011: Introducing the Research Area of Innovation Science / [ed] Sven-Åke Hörte, Halmstad: Högskolan i Halmstad , 2011, p. 55-81Chapter in book (Other academic)
    Abstract [en]

    Given the complex and interdependent nature of innovation, it is a diverse phenomenon which takes place both in high‐ and low‐tech industries. The purpose of this paper is to increase our understanding about low‐tech industries’ innovation‐related activities and the specific capabilities of the companies that influence those. To achieve this purpose this study has performed an empirical analysis of the Swedish context of the Swedish Electroplating and Surface Treatment Industry (ESTI) and the characteristics of the companies operating in it. It investigated how the companies perceived their expertise and innovative activities in comparison with their main competitors. The main types of innovation the ESTI companieshad undertaken in a three‐year period (2004–2006) were studied. The research and development (R&D) and personnel qualification improvement expenditures were explored. The study looked into collaboration and the factors which companies perceived as important in order to collaborate. Our empirical evidence shows that innovation in the ESTI is shaped notby R&D but by other determinants, such as specific and rare capabilities in, for example, processing technologies, logistics, ability to spot, evaluate and exploit external knowledge as well as their ability to establish and sustain intercompany relationships. Strong relationships and integration with customers and suppliers emerge as pivotal for the innovation‐related activities in the ESTI. Additionally, close collaboration, facilitated by a strong intermediate institution, such as the Swedish Association of Surface Treatment Companies (Svensk YtbehandlingsFörening – SYF, also shape the innovation‐related activities in the ESTI.

    Shopping Cart Support2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This is a product development project which has developed a prototype in order to facilitate for people using mobility devices when they want to buy a larger quantity of groceries. The prototype is a shopping cart composed with the upper part of a walker.Today there are many different types of mobility devices used by elderly and people with physical impairment. According to Myndigheten för samhällsskydd och beredskap (MSB) are accidental falls the most common cause of accidents in Sweden.This project has been using Computer Aided Design (CAD) as a tool to create a visual image of the prototype. The advantage of this is to modify the functionality and performance of the prototype on the computer before the modification takes place in the real model. Using human manikins, the CAD model was rendered in natural surroundings to get as true a picture as possible. The prototype is adjustable, why various anthropometric measurements were used to fit to the individual, but not less than the 40th percentile for women, corresponding to a height of 161 cm.The project has resulted in a CAD model and a functional prototype. The prototype has been tested by a user group at Alla Hjärtans Hus (AHH) and received positive feedback. The prototype also received constructive criticism from users, so suggestions can be applied. Suggestions for further development of the prototype have been developed. The prototype needs to be modified and components must be added before it can be used in grocery retailers.

    Rekrytera olika: En kvalitativ studie av fyra olika organisationers val av rekryteringsmetoder2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Thestudy's purpose was to investigate why four different organizations use certain recruitment methods. Based on this purpose, the writers of this study formulated a question about the underlying causes that may affect the choice of recruitment methods in these four different organizations. The study was conducted using qualitative semi-structured interviews with four organizations, two of which appeared in the private sector and two of which appeared in the public sector. The study shows that the four different organizations use a variety of recruitment methods for the filling of vacancies. The choice of the different methods can be based on different underlying causes; organizations' mission, the organization's environment, power and control and the availability of resources. Thus, there may be several ways to understand what it is that makes an organization choosea particular method of recruitment and thus deselect other methods. It is therefore important to understand organizations' individual conditions and that theyall operate in different contexts in which the same recruitment method may not beoptimal for all. Thus, one and the same organization can be influencedby several independent factors whichin interaction with each other helps to shape an organization's entire recruiting process.

    Surface Topography on trimming dies and the influence of wear2010In: Proceedings of the International Deep Drawing Research Group / [ed] R. Kolleck, 2010, p. 345-354Conference paper (Refereed)
    Abstract [en]

    In this paper it is investigated how surface topography on trimming dies influences the wear process. Surfaces on both semi-industrial test dies and dies used in production were analyzed with different surface topography analysis methods. The result shows that the wear process is different on the different sides of the trimming edge. The texture direction of the surface is changed due to wear, with the strongest change on the clearance side of the edge. The roughness on sheet side of the edge is reduced due to a hammering effect from the sheet material. The result on the test dies and the production dies correlates well.

    Abstract [en]

    The higher product requirements (reduced weight, increased safety, lower emissions…) have meant that a larger number of car body parts must be made in advanced high strength steels. With a reduced lifecycle of a car model from 7 to 5 years this leads to a need for reducing the manufacturing cost and lead time for the tool and die design and manufacturing. The main purpose of this investigation is to establish cost- and lead-time reducing guidelines for selection of tool concepts (choice of die materials, hardening methods and geometry) for different production volume scenarios with respect to sheet materials quality (MS-UHSS) and thickness, without increased die maintenance costs. In this study the cutting edge geometry has been evaluated in respect to the cutting edge radius and the angle of the upper tool. Experimental testing together with FE simulation has been used. Results show that an angle of 93° on the upper cutting edge initially can reduce the cutting work by 14%. Results also shows that by using a cutting edge radius of 80µm, the tool “wear in phase” can be more controlled. Wear test up to 150 000 strokes have been made to evaluate different tool concepts using laser hardened cast iron, cast steel and wrought steel as die material. Sheet material tested was 220RP, DP600, DP800, 700MC and DP1000, with a thickness of t=2mm. The result leads to recommendations for industrial verification. Results among other recommendations are: laser hardened EN-JS-2070 up to 500 000 parts against 220RP and Sleipner up to 1 500 000 parts against 1000DP.

    Abstract [en]

    The thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.

    The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.

    The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.

    The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers.

    Analysis and evaluation of the ergonomic simulation software IMMA2014Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis is the final project for the author’s master’s studies at Halmstad University. It has been completed within a research project (CROMM) at the University of Skövde.

    The purpose of the thesis was to analyse and evaluate if the ergonomic simulation software IMMA can be used to support design and evaluation of vehicle design. Four thesis questions were addressed. The objectives were to obtain a demonstrator that shows what the IMMA software can be used for, and to receive initial design data for design of ergonomic car trunks.

    Semi-structured interviews have been held with people who work with vehicle ergonomics at Volvo Cars, Scania and AB Volvo, and needs were identified within the following fields:  position, motion, envelopes, integration, evaluation, visualisation and general needs. An analysis of the results and the IMMA software was performed. The conclusion was that IMMA supports the basic needs for design and evaluation of vehicle ergonomics and therefore needs further development, both modifications and new functions.

    A method from the HFES 300 Committee was used for evaluation of the trunks together with simulations in IMMA. The result showed a variation depending on where in the trunk the box is placed. The analyse lead to the conclusion that the results cannot be seen as fully repeatable or reliable. A new function is needed in order to make it possible to fully evaluate the result.

    The recommendations are to start with development of the sit-positioning and an evaluation module. Although, the development of how to make the tool more time-efficient, user-friendly, repeatable and reliable, must be taken into consideration in each development step.

    Symbolic Characterisation of Commonalities in Testing Software Product Lines2016In: 2016 9TH IEEE INTERNATIONAL CONFERENCE ON SOFTWARE TESTING, VERIFICATION AND VALIDATION (ICST), Piscataway, N.J.: IEEE , 2016, p. 387-388Conference paper (Refereed)
    Abstract [en]

    Validation and verification of Software Product Lines is particularly challenging due to the complex structure and interaction of commonalities and variabilities among products. There are several approaches to specify the structure of such commonalities and variabilities, such as the delta-oriented approach. Building upon such a structure, we propose an approach to avoid redundant analysis in Software Product Lines by extending them to semantic behavioural changes. To this end, we propose to use Differential Symbolic Execution, an automated technique for proving functional behavioural equivalence based on satisfiability modulo theories. Our proposal aims at identifying the behavioural commonalities of one software product relative to another and exploits them in order to establish an efficient model-based testing trajectory.

    Abstract [en]

    The aim of this thesis has been to develop a proposition for a new type of snail barrier, whose function is not based on the use of toxic chemicals or electric current. We have mainly used Fredy Olsson´s methods described in the compendium "Princip- och primärkonstruktion" After a thorough review of previous research and the accompanying definition of criteria, we sketched out six different propositions. By weighting the criteria in a Kesselring matrix, we selected one of the proposals for further development. The main criteria we had to take into account were; the weight of the product, the ability to recycle the material, the price and that it would be modular. The work has resulted in the development of a product that meets all the criteria, and is ready for manufacturing, though field conditions tests that can confirm the effectiveness remains to be done.

    Abstract [en]

    This thesis is in line with the two author’s orientation within the mechanicalengineering program. The orientation is production development and the project hasbeen to develop a new packaging line based on a simple existing one. The existingsystem is located in a dairy plant and have old equipment and low capacity which theplant want to improve.

    The project has given the authors opportunity to use andwiden their knowledge within their area of education.The project includes a lot of research, the theory behind the project is amongst otherthings; production systems, evaluation systems, work ergonomics, models forproduction development, directives, rules and data for the machines and equipmentneeded for the project. Contact has been made with several machine suppliers to findinformation and to get prices.

    The method used was decided during the projects background study, the method isdeveloped by Bellgran & Säften (2005) and is a method designed purely forproduction development. Only applicable parts of the method has been used whichmeans that some parts where left out such as the part for deployment since theproject won’t be realized as of now. The method included a study of the currentsystem and similar production systems as well as interviews with the staff.

    This project has led to a number of concepts for a new production system that worksvery different compared to the old system. The authors are very pleased with theresulting new final concept and the improvements it lead to which is technical andeconomical. The main results is 50% improved capacity and reduced heavy manualtasks which has resulted in less need of line operators.
