    Energy and Exergy Analysis of District Heating Systems2012In: 13th International Symposium on District Heating and Cooling: 3rd of September – 4th of September: Copenhagen, Denmark, 2012, p. 55-60Conference paper (Refereed)
    Abstract [en]

    The concept of exergy is defined and applied to district heating systems. The influence from different reference state conditions and system boundaries are explained in some detail. The aim is to show the simplicity and value of using the concept of exergy when analyzing district heating processes. The exergy factor is introduced and applied for a number of Swedish and Danish district heating systems. This varies from 14.2% to 22.5% for Swedish district heating systems. The higher the exergy factor, the more the exergy losses in the passive conversion towards space heating. Large losses revealed in an exergy treatment of a process should be seen as a challenge to achieve technical improvements of the system.

    On district heating and cooling research in China2014In: Proceedings from the 14th International Symposium on District Heating and Cooling: September, 6-10, 2014: Stockholm, Sweden, Stockholm: Swedish District Heating Association , 2014, p. 325-332Conference paper (Refereed)
    Abstract [en]

    The growth of the Chinese district heating sector has been very rapid during recent years. No other country in the world can show the same rapid growth of district heating systems during the last decades. Heated building area increased six times between 1995 and 2008 according to the Chinese district heating statistics. China has also enjoyed strong growth of scientific articles and papers published about district heating in recent years. During 2010-2012, one third of all international scientific journal articles and conference papers about district heating came from Chinese scientists, while Swedish researchers accounted for one quarter. It is important to identify the Chinese district heating and cooling research to judge the potential for future collaborative research on district heating systems between Sweden/Europe and China. Until 2013, Chinese district heating and cooling scientists have published 205 international publications on district heating and 36 publications on district cooling. In this paper, these articles are mapped and summarised with respect to topics, active research institutions, and their technology focuses. Another approach is to grasp the Chinese interest for more diversified heat supply, since many new systems are established and thereby have more degrees of freedom when choosing by various heat supply and technology options.

    Evaluation of a human-robot collaboration in an industrial workstation2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The fast changes in the industry require improved production workstations which ensure the workers' safety and improve the efficiency of the production. Technology developments and revised legislation have increased the possibility of using collaborative robots. This allows for new types of industry workstations where robots and humans cooperate in performing tasks. In addition to safety, the design of collaborative workstations needs to consider the areas of ergonomics and task allocation to ensure appropriate work conditions for the operators, while providing overall system efficiency. By facilitating the design development process of such workstations, the use of software simulations can help in gaining quality, save time and money by supporting decision making and testing concepts before creating a physical workstation, in turn, aimed to lead to better final solutions and a faster process of implementation or reconfiguration. The aim of this study is to investigate the possibility of having a human-robot collaboration in a workstation that is based on a use-case from the industry. The concept designs will be simulated and verified through a physical prototype, with which ergonomic analysis, time analysis, and risk assessments will be compared to validate the resultant collaborative workstation.

    Laser sintering of ceramic materials for aeronautical and astronautical applications2017In: Laser Additive Manufacturing: Materials, Design, Technologies, and Applications / [ed] Milan Brandt, Amsterdam: Woodhead Publishing Limited, 2017, p. 373-398Chapter in book (Other academic)
    Abstract [en]

    Ceramic products have been manufactured for many decades via conventional techniques such as extrusion, oven sintering, and casting. However, these methods have several inherent disadvantages with regard to the possible shape and structure, which limits their application range. The advent of laser additive manufacturing (LAM) is a key enabler in creating ceramic components with considerably greater design freedom. The technology is allowing the creation of ceramic components that not only meet the increasing material requirements of aero/astro applications but also provide new opportunities in terms of the complex structures that can now be produced. Ceramics represents a new frontier for these LAM systems – one with many challenges and research needs; however, the material properties that ceramics offer over polymers and metals make the additive manufacturing of ceramic components an enticing engineering opportunity for aerospace, astronautical and potentially many other technology areas. This chapter presents an overview of the state of the art of ceramic materials in LAM for aerospace and astronautic applications. Section 14.2 explains the fundamentals of ceramic materials and includes examples of their traditional manufacturing methods. Section 14.3 focuses on the application of ceramic materials to the challenging engineering realm of aeronautics and astronautics, accompanied by examples from their main application areas (eg, thermal and ballistic shielding). Section 14.4 goes into depth on LAM, explaining the challenges and implications of laser processing ceramics, the benefits of the approach and examples from the current state of the art. Finally, 14.5 Future developments, 14.6 Conclusions highlight some of the likely future developments in the area and conclude the chapter. © 2017 Elsevier Ltd. All rights reserved.

    Mechanical behaviour of additively manufactured lunar regolith simulant components2019In: Proceedings of the Institution of mechanical engineers. Part L, journal of materials, ISSN 1464-4207, E-ISSN 2041-3076, Vol. 233, no 8, p. 1629-1644Article in journal (Refereed)
    Abstract [en]

    Additive manufacturing and its related techniques have frequently been put forward as a promising candidate for planetary in-situ manufacturing, from building life-sustaining habitats on the Moon to fabricating various replacements parts, aiming to support future extra-terrestrial human activity. This paper investigates the mechanical behaviour of lunar regolith simulant material components, which is a potential future space engineering material, manufactured by a laser-based powder bed fusion additive manufacturing system. The influence of laser energy input during processing was associated with the evolution of component porosity, measured via optical and scanning electron microscopy in combination with gas expansion pycnometry. The compressive strength performance and Vickers micro-hardness of the components were analysed and related back to the processing history and resultant microstructure of the lunar regolith simulant build material. Fabricated structures exhibited a relative porosity of 44–49% and densities ranging from 1.76 to 2.3 g cm−3, with a maximum compressive strength of 4.2 ± 0.1 MPa and elastic modulus of 287.3 ± 6.6 MPa, the former is comparable to a typical masonry clay brick (3.5 MPa). The additive manufacturing parts also had an average hardness value of 657 ± 14 HV0.05/15, better than borosilicate glass (580 HV). This study has shed significant insight into realising the potential of a laser-based powder bed fusion additive manufacturing process to deliver functional engineering assets via in-situ and abundant material sources that can be potentially used for future engineering applications in aerospace and astronautics. © 2018, IMechE 2018.

    Bearbetningsmaskin för fälgar i kolfiberkomposit2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The following thesis has been performed in cooperation with Koenigsegg Automotive AB, which develops, manufactures and sells high-performance sportscars. Koenigsegg offers rims made completely from carbon fiber composite, which yields substantial benefits in stiffness and weight compared to their traditional metal counterparts.

    After the manufacturing of the rims, some trimming is necessary in the contact surface between rim and tire. The purpose of this thesis has been to examine the possibility of performing the necessary trimming in-house in Ängelholm, by designing a special tool.

    The project began with a literature study, where possibilities and difficulties of machining carbon fiber composites were examined. As a result of the study, the manufacturing process turn-milling was chosen, and a number of concepts were generated. Through a series of evaluations, one concept was further developed to a final product.

    The suggested product is complete with calculations, analyses and drawings, which gives Koenigsegg a better insight of future possibilities. A solid foundation for future CE-marking has also been produced. The project has followed Fredy Olssons methods of Engineering Design.

    Smart Control: En reaktion på EU:s ekodesignkrav2012Independent thesis Basic level (degree of Bachelor), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    The purpose of this thesis is to assist the Swedish energy company NIBE Energy Systems in their studies of adaptive regulation applicable to electrical water heaters. Due to coming energy classifications of these appliances in the European Union, NIBE Energy Systems needs to use adaptive regulation, called Smart Control, to keep their products in the best possible energy class and remain competitive to the market. By using this Smart Control regulation a 2-3 % improve-ment of efficiency can be credited the system. This is a small number, but heavily needed, since the energy classes are based on the idea that the European Union is provided with electricity from coal condensate power resulting in a 40 % maximum efficiency. Furthermore, doing noth-ing will result in some water heaters not being approved to use on the market from 2015 due to low efficiency. The thesis is made out of three sections; product-/literature studies of products already commercially available using similar principles, data analysis on existing Smart Controlled water heater and recommendations to the company for future development of their own system. Limitations have been made through simplified calculations and thermodynamic assumptions. A conclusion can still be made from the thesis; electrical water heaters using Smart Control saves 10 - 15 % of electrical energy use today in a real world environment. Main sources to this thesis have been data analysis, Internet, brochures and conversations with the mentors.

    Abstract [en]

    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.

    Kraftmätning på cykelpedal2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report will describe the development of a subsystem for force measurement on bicycle pedals. The force is going to be used as a control parameter in a motor controller to control an electric motor on an electric bicycle. The report focuses on force measurement and will not process any control system. There has also been a survey of alternative power supplies to the circuit boards to be used in this project. Energy Harvesting has been investigated as an alternative source. The aim of the project is to measure the force applied on the pedal in a good way for use in a control system.This work resulted in that the force applied on the pedals was measured on the crank arms. The force was being measured by strain gauge sensors in a test rig designed in this project. The force signal can be used in the intended control system. This report has explained when, during a pedal stroke, the force should be measured. Processing of the signal will be done furthermore in the motor controller to fit the requirements set by the control system.

    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.

    CASEUS: Din hjälpande hand2017Independent thesis Basic level (university diploma), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Development and modernization takes place all the time and everywhere in today's society.

    Although we handle and slices hard cheese in the same way that we did decades ago. The way

    we handle cheese nowadays is not only unhealthy, but can also be a difficult moment for

    some people.

    The goals to develop a functional, modern and food-approved kitchen tool adapted to today’s

    society are the main factors for this bachelor thesis. Along with stakeholders for the project,

    the requests and demands set up for the prototype progressively have been worked out. Wellknown

    methods and market surveys have been used to ensure the need of the product.

    Researches in relevant subjects have also shown that the market is in need of a new product.

    The product called CASEUS has after studies shown to have a broad target group. The name

    CASEUS, came from the Latin word for cheese (Caseus) and from the English word case, as

    the product will be like a case around the cheese. The kitchen tool is designed with a simple

    mechanical solution, in a hygienic material. The handle is designed according to EU: s

    standard dimensions for handles. Therefore, it is considered suitable for the majority of the

    population in Sweden. Thus, there is a market for the product both at hotels and restaurants, as

    well as in private households.

    In the final stage of the project a prototype of CASEUS has been produced by Havd Group,

    which is a stakeholder in the project. The prototype has been funded by a scholarship and

    contributions from ALMI Business partner.

    To be able to continue with CASEUS after the end of the project, new possible working paths

    have been investigated. With promotion, more scholarship or a collaboration with an existing

    manufacturer in the industry, the project team hopes to be able to get CASEUS out on the

    market.

    Virtual Prototyping and Physical Validation of an Inverted Pendulum: "Sea-Calf Bot"2015Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The work is motivated by the goal of linking reality and model, and to see if there is an opportunity to develop an inexpensive educational tool for training in cyber-physical systems.

    This project has investigated the possibilities to build a cheap inverted pendulum with controller and connect this with the modeling language Acumen. Acumen models is used for comparison with the actual prototype.

    To solve these problems has a 3D printer been used to create hardware, Arduino UNO for control and Raspberry Pi for enable communication with Acumen over WLAN.

    The result was a cheap inverted pendulum, which can be built for a cost around 750 SEK. Graphs created in Acumen and from data collected from sensors can be analyzed.

    With a model of the inverted pendulum system, the results show that Acumen can be used in the development of cyber-physical systems. There are differences between model and reality but also similarities.

    Abstract [en]

    Today many shooting ranges uses outdated systems for controlling their shooting targets. These systems may be inconvenient to both use and to program. During this project a new system for controlling shooting targets is developed, togheter with a rotation target prototype for air pistol shooting.

    The project aims to allow more members to easily learn how to use and to program their system. A system that is easy to use will also free more time for a shooting leader to superintend the shooters.

    The core part of the system is its reciver, which is epuipped with a Bluetooth Low Energy module to establish a connection with a remote handheld device.

    Both the reciever and rotation target prototype is developed. Different strategies for meeting the specified requirements are evaluated.

    The result is a system that recievs a program sequence from a handheld unit and controls the rotation target prototype as specified by the user.

    Geotermi i Ungern: Undersökning av Ungerns energisituation inriktat på geotermi samt kapacitetsfaktorn för det största geotermiska värmeverket i Mellaneuropa.2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Hungary’s share of renewable energy in 2010 was 7.9 %, and their renewable energy goal for 2020 is 14.65 %. Geothermal energy is one option that could help to achieve the goal, since Hungary has favorable bedrock, the temperature gradient is above average and thepermeability is high. Today Hungary is importing just over half of its primary energy supply. Because of political conflicts between nations Hungary wants to expand its own production of energy. One of the major investments implemented was to build the largest geothermal heating plant in central Europe, located in Miskolc. This degree theses aims is to raise the capacity factor for this heating plant. To achieve this objective, a survey of how grain dryers and absorption chillers could increase the heat load in the summer has been performed. With grain dryers that only dries wheat, the capacity factor for the geothermal heating plant in Miskolc increased by 2.6 % and by 4.4 % for the absorption chiller. Although surveys have been carried out for a specific case the idea can be implemented in other heating plants.

    Keywords: Capacity factor, geothermal energy, wheat dryers and absorptions chiller.

    Equipment changeover reduction of a production line2018Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The growing competition for manufacturing companies is placing increased demand on fulfilling customer requirements with as high quality as possible as quick as possible. To meet the tougher competition, it is common that companies implement various tools and methods such as Lean Manufacturing, Continuous Improvement and Single Minute Exchange of Dies (SMED). Implementing these helps to reduce the risk of production failures while increasing efficiency thus increasing profit.  This thesis brings up the implementation of a tool within Lean Manufacturing called SMED to a production line with the aim to increase the machine availability through reduction of the equipment changeover.  The thesis is a qualitative case study where the authors use interviews, observation and time measurement to gather relevant data which are then analysed for the goal of this thesis which is to reduce the complete equipment changeover time of the production line in Ämnesverkstaden. All the relevant data which was collected resulted in an implementation of a SMED mind-set and an instruction manual with a complementary list of necessary changes.  The authors believe that this study can provide useful information and knowledge when introducing SMED as well as an approach the operators can use in the future to help reduce the equipment changeover.

    Återanvändning av filtmaterial2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The thesis work is a collaboration with the company Nordifa AB. The work is about making use of the waste material Nordifa gets after manufacturing different products and thereby helping the company to contribute to a cleaner environment. With the waste material the company's range of products will be developed. 

    By weighting requirements and function, the students presented a product in terms of the result. This required a new type of tool in three parts to use in the pressing machine. Drawings for this was developed and sent to Plåtcenter who created the prototype tool. The students have used a design process adapted to the project, which gave the opportunity to focus on what’s relevant which in this case meant finding an optimal production process. 

    The process gave five solution proposals, that after the weighting of requirements led to one which was chosen for continued development. The final concept became a production process in which all waste is used and which provides a design that can be used in multiple material rolling processes for different products. With the help of Rapid Granulator AB, the proposal could become a prototype, as they helped to test grind of the material, which led to the result. This solution also minimized manual work, and gives all staff the opportunity to understand and perform the work process.

    A final concept has been produced and when the project has been completed, the prototype tool has been developed and tested at Nordifa. Further work exists and is based primarily on a decision by Nordifa if they choose to make use of the proposal.

    Konstruktion av "log strike"-testrigg för utombordsmotorer2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The goal for this project, carried out with directions from Cimco Marine AB, has been to design a concept construction for a “log strike” testrig for outboard motors. Cimco Marine AB has developed a diesel powered outboard motor mainly for professional use. The diesel engine used is an engine from the automotive industry that has been converted for marine use. The engine is located on a gearbox and underhouse that transfer the power via two belts down to the propeller.

    A “log strike” occurs when a boat with an outboard motor runs over a log floating in the surface of the water. When this happens a collision between the part of the outboard motor under the waterline and the log is a fact. To ensure that the outboard motor manufactured by Cimco Marine AB manage the loads a high speed log strike produces, they want a test rig to test this. One can compare this test with the crash tests performed in the vehicle industry.

    In the beginning of the project, time was spent on research and information gathering. It was then decided that the rig should consist of a sled that is propelled against the underhouse of the outboard motor. After this, the project was split in smaller units and every unit was considered separately before they were put together again as a whole. The construction project has followed the design method developed by Fredy Olsson.

    The end result is a concept design of a “log strike”- test rig, adapted to the requirements set up by Cimco Marine AB.

    Komprimering av medicinskt avfall2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Hälsoteknikcentrum Halland are working with different projects to find new technical solutions for problems in healthcare, they brought up the problem with the medical waste disposal together with representatives from Hallands Hospital in Halmstad. Today the nurses and caretakers experience the medical waste disposal as unpleasant since it means they have to deal with contaminated waste, the hospital is eager to develop a product that compresses the waste and improves the work environment for its employees.

    The product shall compress bags of 150 liters of medical waste, this shall be done in a user-friendly way based on specific requirements, the specification was developed in consultation with hospital employees. Through different experiments and examination of different methods, the most appropriate method to compress the bags were to press them. After developing the idea to a functioning method a prototype was made. The prototype uses pneumatics to press the air out of the bag, the contaminated air is filtered through an absolute filter and the bag is compressed over 50%.

    This graduate thesis has included a number of tasks, to read up on different areas, problem solving, construction and innovation. This has resulted in a well functioning prototype that meets the requirements.

    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.

    Optimization of Flexplate2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    From 2019, all new Volvo Powertrains will be electrified, also including ICE based Powertrains. In the ICE based Powertrains with automatic transmission, a flexplate is connecting the crank shaft to the automatic transmission to transfer the power. The flexplate needs to handle torque peaks from the combustion, crank shaft whirl and axial forces generated by the torque converter. The combustion torque load is maximized at every ignition, but the load is also dependent on engine speed/load and gearbox shifts. All these loads applied to the flexplate means that the plate will be exposed to high stress levels. These high levels of stress make the flexplate more likely to break and thus, shorten its lifespan. Therefore, the objective of this thesis was to generate new optimized design proposals of the plate with minimized stress levels using the method Simulation Driven Design. Also, to understand the result, a parametrical study was performed using Design of Experiments. Using Simulation Driven Design, several concepts were generated but only two showed valid results, and they were optimized using parametrical optimization and Design of Experiments in Catia V5. Also, an attempt at a topological optimization was performed in Inspire, but the model was to complex and could not be accurately replicated in the program, making the topological optimization impossible to do. With a combination of parametrical optimization and Design of Experiments, the two concepts showed a reduced stress level of 16.4% and 11.1% compared to the original design. They also showed an increase in deformation and a slight decrease in weight. Knowing this, a conclusion could be made that Simulation Driven Design is a great method to use in product development. The results show that the combination of parametrical optimization and Design of Experiments can be used efficient during the optimization process in product development.

    IMPLEMENTATION OF   ”MATRIX DATA CODE’’ MARKING ON GEAR KITS: Marking and reading of the marked data on the pinion and crown wheel after hardening and phosphating processes2015Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This thesis has been performed in cooperation with the companyMeritorHVSABin order to implement amatrix data codes marked on gear kits for reducing potentialhuman errorwhen inputtingthe information inside thecompany's business system. Asustainablemarkingis the basis forproducttraceability to followa product'swayfrom theraw materialto finished product so that they can betracedthroughouttheir life cycle. To investigate thecurrent technology, two different marking andreadingmethods were tested: a laser and dot peen method. It has been found that the dot peen method was more suitable for Meritorto mark thewheel because the markswere clearerand couldbe readbothwith the naked eyeand scanner. Conversely, the contrast of the mark created by the laser method was not as readable as the dotted marks and there has been a larger risk to be mechanically removed because of its thin thickness.As a result, the matrix data code made by dot peen method has been fully implemented on the pinion’sandcrown wheel’s production in Meritor.

    Abstract [en]

    SAPA´s resource of waste heat is the basis for this thesis to investigate the possibility of energy assets in their cooling water and possible uses for it. The energy in the waste water is greater than the current need which has three uses which are (1) heating the factory, (2) converting liquid propane to propane gas and (3) local domestic heating. The average energy load that is available is 1, 7 MW and the average temperature in the cooling water is 41°C. The total energy load at dimensioning out side temperature is approximately 1,6 MW for the three current uses. The temperature is currently too low to be used directly in the existing systems so an upgrade is needed. The district heating has the highest temperature requirements at 100°C in the winter. To reach the relatively high temperatures required a hybrid heat pump proves to be a suitable solution due to a good Coefficient of Performance (COP). The disadvantage is that at the moment hybrid heat pumps have to be tailor made and are therefore very expensive. The investment required to extract the most amount of surplus energy is large due to the expensive tailor made hybrid heat pumps and the high cost of laying underground heat transferring pipes which leads to long pay off times as the value of surplus heat from waste water is low.

    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.

    qbits: Kombinerar användning och förvaring av bits2011Independent thesis Basic level (university diploma), 15 credits / 22,5 HE creditsStudent thesis
    Abstract [en]

    Aren’t you tired of never finding stuff? Take a bits as example, do you store these lose in your toolbox or carpenter belt? What if you could have it all accessible and assembled in a tool, always at arm’s reach?

    Today bits are used together with electric screwdrivers and handheld screwdrivers in a greater spread. For these different types of storage, from pure storage boxes to complex tools with storage built in, exist. The professional craftsmen commonly use some kind of box where the bits can be stored. Even so they tend to store their bits loose in a carpenter belt or toolbox, since they want the speed and accessibility of carpenter belt over the storage box’s tidiness.

    The project was started in the fall of 2010 and a referents group was early put together to ensure that the developed product became as user-friendly and attractive as possible. The referents group contained our target group, professional craftsmen and other competent persons within the field. In cooperation with the referents group a needs and wants list was put together to make sure that the product satisfice the need.

    The lack of a good storage solution has led to a unique product which suit for both usage and storage of bits. Through combining the carpenter belt and the storage box speed, accessibility and tidiness is obtained. A solution suggestion with a prototype was created which satisfied the set needs and wants. The solution was presented for the referents group and the response was good but improvements suggestions were given. These were taken and work began on a new version.

    The result became a new product, qbits, the unique tool which combine usage and storage of bits.

    Abstract [en]

    Product Development (PD) in Small and medium-sized Firms (SMEs) is a long-neglected research area, and little cumulative work has been conducted previously. The purpose of this paper is to provide a first overview of the area of PD in SMEs. In doing so, we draw upon a sample of 149 peer-reviewed research papers selected from an initial sample of 5694 papers. The review provides tentative answers to issues such as the analytical and methodological approaches of the papers, which topics or areas of research have been focused on by previous scholars, and what kinds of topics that are well covered.
