    Evaluation of Durability of SOG-layers on Steel Surfaces by Wear and Scratch Tests2014Conference paper (Refereed)
    Abstract [en]

    Steel moulds with high precision surfaces are being used in various branches. Process aspects, like tool life and tribological properties, as well as design issues are of great importance. This work summarises experimental studies performed to test durability properties of SOG (spin-on-glass)-layers on steel surfaces. This coating technique is based on a newly developed method for surface preparation of tools which has been demonstrated to be durable for more than 66.000 replications in injection moulding processes without loss of surface fidelity. The procedure allows surface roughness reduction from approximately 200 nm Ra down to some few nm for high gloss applications, as well as easy transfer of large-area functional nanostructures on complex 3D surfaces.

    Three different types of surfaces were investigated: SOG-layered metal surfaces with three different layer thicknesses, one ingot casted and one electro slag remelted material (with hardness level of 950 and 2500 MPa, respectively). The metal surfaces were ground and polished to mirrorlike finishes.

    Three circular samples of each type were rubbed against a hard steel ball of 6.35 mm radius on a commercial pin-on-disk tribometer. To resemble the molding process a sliding speed of 2 mm/s and a load of 8 N were chosen. The tests were performed with 5 minutes intervals until the first damage on the surface were observed. In parallel, scratch tests were performed in the same tribometer. The surfaces were measured in-situ by a portable microscope and a stylus, and afterwards by a white light interferometer and scanning electron microscope to evaluate the size of the wear/scratch traces.

    The surface type with the longest time to damage and/or smallest wear/scratch traces was considered to be the most durable one.

    Functional parameter screening for predicting durability of rolling sliding contacts with different surface finishes2018In: Surface Topography: Metrology and Properties, ISSN 2051-672X, Vol. 6, no 2, article id 024005Article in journal (Refereed)
    Abstract [en]

    The reliability and lifetime of machine elements such as gears and rolling bearings depend on their wear and fatigue resistance. In order to screen the wear and surface damage, three finishing processes: (i) brushing, (ii) manganese phosphating and (iii) shot peening were applied on three disc pairs and long-term tested on a twin-disc tribometer. In this paper, the elastic contact of the disc surfaces (measured after only few revolutions) was simulated and a number of functional and roughness parameters were correlated. The functional parameters consisted of subsurface stresses at different depths and a new parameter called 'pressure spikes' factor'. The new parameter is derived from the pressure distribution and takes into account the proximity and magnitude of the pressure spikes. Strong correlations were found among the pressure spikes' factor and surface peak/height parameters. The orthogonal shear stresses and Von Mises stresses at the shallowest depths under the surface have shown the highest correlations but no good correlations were found when the statistics of the whole stress fields was analyzed. The use of the new parameter offers a fast way to screen the durability of the contacting surfaces operating at similar conditions. © 2018 IOP Publishing Ltd.

    Effect of the measurement size on the robustness of the assessment of the features specific for cylinder liner surfaces2014In: Surface Topography: Metrology and Properties, ISSN 2051-672X, Vol. 2, no 1, article id 014013Article in journal (Refereed)
    Abstract [en]

    The quality of the cylinder liner surface is of great importance due to its impact on the fuel/oil consumption and emissions of the internal combustion engine. A good liner function depends on the size and distribution of the deep honing grooves and the amount of the cold work material (Blechmantel) left inside the grooves after finishing. A fast evaluation of these features requires optical three-dimensional measurements with a large area and good resolution, but many interferometers used today have limited resolution when measuring larger areas. To find out how the measurement size and resolution would affect the quantification and the variation of the parameters, two objectives, 2.5 ×  and 10 × , were used for measuring a cylinder liner from a truck engine. The Blechmantel was of special interest as it first comes into contact with piston/rings, detaches as particles and wears the running surfaces. The 2.5 ×  objective showed more robust assessment than the 10 ×  one, manifested by a lower coefficient of variation for the parameters describing the features: Blechmantel, groove width and height, groove balance and number of grooves. This means that fewer measurements are required if a 2.5 ×  objective is used in production and hence the time and cost of the liner would be decreased. © 2014 IOP Publishing Ltd.

    Novel testing methods for screening the tribological performance of ring-liner surfaces2018In: Surface Topography: Metrology and Properties, E-ISSN 2051-672X, Vol. 6, no 3, article id 034017Article in journal (Refereed)
    Abstract [en]

    The piston system accounts for about the half of the frictional losses of internal combustion engines and requires special testing methods to understand and improve its function. The most common way to screen the surface performance is to rub ring/liner segments against each other in a reciprocating manner. However, short reciprocating tests have intrinsic low sliding speeds, unable to reach the mixed/hydrodynamic regimes found in the engine, especially at the mid-stroke. This paper presents a rotating test for the oil control ring, which has the largest frictional losses of all other rings. Both reciprocating and rotating tests were conducted using different in-house developed modules and fixtures. Twin land oil control rings against liners with two different finishes commonly used in heavy duty diesel truck engines were tested under similar loads and speeds as in a real engine. Engine oil 5W-30 and room temperature was used for all the tests. Sliding speed, load, friction force and electrical resistance were recorded during the tests. The results show a clear discrimination of the different liner finishes depending on the lubrication regime present.

    Influence of measurement and filtering type on friction predictions between cylinder liner and oil control ring2016In: Tribology International, ISSN 0301-679X, E-ISSN 1879-2464, Vol. 100, p. 7-17Article in journal (Refereed)
    Abstract [en]

    It is of a vital importance to reduce the frictional losses in the engines and hence the fuel/energy consumption. The major contributors to this are the oil control ring and cylinder liner interactions difficult to understand when comparing the experimental and theoretical results. The latter largely depend on the liner surface measurement and filtering type used in the simulations. Therefore, low-pass and high-pass filtrations were applied and the friction behaviors between the filtered liner surfaces and a perfectly flat ring surface were simulated for different engine speeds. The surfaces low-pass filtered by lower cutoffs showed higher friction, while the type of de-noising revealed about two and a half times higher friction. Stylus surfaces showed larger friction than the interference ones. © 2015 Elsevier Ltd. All rights reserved.

    Influence of Surface Waviness on Predictions of Friction between Cylinder Liner and Oil Control Ring2015In: Proceedings of the 42nd Leeds – Lyon Symposium on Tribology, September 7-9, 2015, Lyon, France, 2015Conference paper (Refereed)
    Abstract [en]

    It is of a vital importance for automotive industry to reduce the frictional losses in internal combustion engines and hence their fuel consumption and CO2 emissions. The major contributors to this are the oil control ring (OCR) and cylinder liner interactions. These interactions are of complex multi-physics and multi-scale nature and many attempts have been made to improve the modelling and understanding of the phenomena involved. Even though continuous improvements have been made (see for ex. [1-3]), the form, waviness and roughness variation of real engineering surfaces still cause a large scatter in the results. The most of the models include measured liner surfaces, which are then filtered to capture the micro-effects of the roughness scale. However, by doing this, the contact conditions change (asperity contact distributes more evenly, see Fig. 1) such that the part of the boundary friction reduces and the part of the hydrodynamic friction increases accordingly for a given engine speed. This study focuses on one of these multi-scale problems, namely on how the 3D measurement type/size and filtering affects the predictions of friction between cylinder liner and OCR of truck engines. Two types of 3D liner surface measurements were investigated: (i) interference (with an objective of 2.5x, size of 2.5x3.3mm) and (ii) 4x8mm stylus measurement. The form was removed by fitting and subtracting a 2nd order polynomial and the waviness was filtered out by using a robust Gaussian filter with three different cutoffs: 2.5mm, 0.8mm and 0.25mm. The friction behaviours (i.e. the Friction Mean Effective Pressure-FMEP) between the primary/ filtered liner surfaces and a perfectly flat ring surface were then simulated for different engine speeds. The relative errors of the OCR’s FMEPs with respect to the primary surface were evaluated and results discussed.

    On-line arithmetic for real-time control of microsystems1999In: IEEE/ASME transactions on mechatronics, ISSN 1083-4435, E-ISSN 1941-014X, Vol. 4, no 2, p. 213-217Article in journal (Refereed)
    Abstract [en]

    The integration of microcontrollers within mechanical systems is a current trend. However, decreasing the size of the system and satisfying higher precision requirements make it necessary to reevaluate the common signal processing techniques for controller implementations, because limited controller size, computation speed, and power consumption become major topics. In this paper, we demonstrate that serial computations with the most significant digits first, that is, on-line arithmetic, offer an important potential for real-time control. They enable a combination of traditional functions, such as analog-to-digital converters and control data computations. This leads to very efficient controller implementations with small size, high speed, and low power consumption. After a brief description of the requirements and challenges of microsystem controller design, the use of on-line arithmetic for real-time control is proposed. A short introduction to on-line arithmetic is given and control-specific implementation guidelines are presented and finally applied to a simple test system.

    Experimental tissue parameter identification for use in endoscopic urological haptic simulators2009In: Control and Automation, 2009. MED ’09. 17th Mediterranean Conference on, Piscataway, N.J.: IEEE Press, 2009, p. 1131-1136Conference paper (Refereed)
    Abstract [en]

    A method is developed for obtaining parameters for tube-like soft-tissues, to be used in urological haptic simulators. A device was designed and built that allows the acquisition of forces and displacements during endoscope insertion in a tubelike soft tissue. The device consists of a mechatronic ball screw mechanism, with a 6 DOF force/ torque sensor attached to it. The steel shaft representing the endoscope, is commanded to follow desired trajectories with micrometric accuracy under the application of an IPD controller, implemented on a dSpace 1103 system. The experimental data acquired is fitted to polynomials to yield a tissue model that can be used to predict insertion forces required for haptic simulator feedback.

    Title: The auditor’s recommendations to small businesses in the choice of K2 and K3

    Authors: Christopher Dimovski and Dennis Carlsson

     Published: Spring 2014 

    Background: The background of this study is the introduction of the new K-regulations. For small businesses, there is a possibility to choose between the rule-based K2 and the principal-based K3. It becomes mandatory to apply the K-regulations from 2014. We want with this study understand and explain the significance of the auditor and its recommendations to small businesses in the choice between K2 and K3.

     Aim: The aim of this study is to describe how the auditor makes recommendations to small businesses in the choice between K2 and K3 and through that create an understanding of what influence the auditor have when it makes recommendations and at the end contribute to the building of models.

     Formulation of problem: How can we understand and explain the auditor’s recommendations to small businesses in the choice of K2 and K3?

    Methodology: We have used a qualitative method where we have interview eight auditors. All auditors was authorized auditor, but with different experience and from accounting firms of different sizes.

    Results: The study shows that the auditor is crucial through its recommendations to small businesses in the choice between K2 and K3. The basis of the recommendation of the auditor is the need of the business depending on the business’ unique situation. The situation of a business is affected by the relationship to stakeholders and the financial position of the business. Two starting points have been identified which is the basis when the auditor view the business’ needs and recommend a regulation (K2 or K3). The auditor recommends a regulation based on the relationship to stakeholders, the stakeholder perspective. The auditor even base recommendations on the financial position in the business, which create possibilities to earning management which aim is to adjust the earnings to pay as little taxes as possible, which is the earning and tax perspective.

    GPS/Optical Encoder Based Navigation Methods for dsPIC Microcontroled Mobile Vehicle2010Independent thesis Advanced level (degree of Master (Two Years)), 30 credits / 45 HE creditsStudent thesis
    Abstract [en]

    Optical encoders are being widely suggested for precise mobile navigation. Combining such sensor information with Global Positioning System (GPS) is a practical solution for reducing the accumulated errors from encoders and moving the navigational base into global coordinates with high accuracy.

    This thesis presents integration methods of GPS and optical encoders for a mobile vehicle that is controlled by microcontroller. The system analyzed includes a commercial GPS receiver, dsPIC microcontroller and mobile vehicle with optical encoders. Extended kalman filtering (EKF), real time curve matching, GPS filtering methods are compared and contrasted which are used for integrating sensors data. Moreover, computer interface, encoder interface and motor control module of dsPIC microprocessor have been used and explained.

    Navigation quality on low speeds highly depends greatly upon the processing of GPS data. Integration of sensor data is simulated for both EKF and real time curve matching technique and different behaviors are observed. Both methods have significantly improved the accuracy of the navigation. However, EKF has more advantages on solving the localization problem where it is also dealing with the uncertainties of the systems.

    Genusanalys av två kvinnliga karaktärer i fantasyserien Game of Thrones: "Fantasy is hardly an escape from reality. It's a way of understanding it." (Lloyd Alexander)2014Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Denna uppsats analyserar hur genus gestaltas i fantasyserien Game of Thrones. Analysen är baserad på två kvinnliga gestalters skildringar i den första säsongen av teveserien. De två valda karaktärerna, Daenerys Targaryen och Arya Stark, analyseras och jämförs med Yvonne Hirdmans genuskontraktsteori och Paulina de los Reyes och Nina Lykkes intersektionalitets begrepp men även med Maria Nikolajevas schema om hur manligt och kvinnligt gestaltas i litterära texter. Resultatet visar att det förekommer en genuskontraktspakt i karaktärsskildringarna men också att maktpositionerna mellan manliga och kvinnliga karaktärerna beror på andra intersektionella kategorier än enbart kön. Undersökningens resultat tyder även på att Daenerys och Aryas karaktärer bryter mot de stereotypa skildringarna i Nikolajevas schema. Orsaken kan vara att genuskontraktet finns djupt inpräntat i våra samhällsnormer om hur manligt och kvinnligt bör vara. Mannen förväntas vara den starka och beskyddande medan kvinnan förväntas vara den svaga och omhändertagna. En annan anledning till att stereotyperna är svåra att bryta kan vara författarnas rädsla att läsarna inte kommer att kunna identifiera sig med karaktärerna.

    Motivation i ämnet svenska som andraspråk: En studie om motivation i ämnet svenska som andraspråk bland högstadieelverna2015Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Syftet med denna uppsats har varit att undersöka vilken motivationsorientering, integrativ eller instrumentell, som är den mest framträdande bland svenska som andraspråkselever samt vilken motivationsfaktor är den som är mest avgörande för detta. Uppsatsen undersöker även vilka strategier lärarna tar sig till för att väcka och upprätthålla elevernas motivation. Studien är genomförd på en högstadieskola och baseras på både kvantitativ och kvalitativ metod där elevernas enkätssvaren kompletteras med lärarintervjuer. I undersökningen användes även första- och andraspråksinlärningsteorier samt teorier om integrativ och instrumentell motivation vid andraspråkinlärning.  

    Resultatet visar att eleverna drivs främst av den instrumentella motivationen och att betyget är den mest framträdande motivationsfaktorn. Studieresultatet tyder även på att lärarna är lyhörda och medvetna om motivationens betydelse för andraspråksinlärning eftersom undersökningen visar att deras elever anser sig nöjda med den grad utmaning och motivation som undervisningen erbjuder dem.

    Studenters upplevelse av vad som påverkar studenters sömnvanor2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Mental illness is a public health problem that extends through all age groups. Mental illness is highest among young people aged 16-24 years where problems with sleep are part of mental well- being.

    Aim: The aim of the study was to investigate students' perception of what affects sleep habits for higher studies.

    Method: Interviews were conducted with six students aged 20-30 years at a university in southwester Sweden. The interviews were recorded, transcribed verbatim, and then analyzed. Analytical method was a thematic analysis in which three themes emerged. Consideration was given to the ethical aspects as well as the informed consent of the participants. The data were treated confidentially. The study was done in collaboration with the Student Health Care.

    Results: The analysis revealed three themes: New procedures affect sleep, Stress and Performance affects sleep patterns and Healthy living. Factors that influence sleep habits among students were routine, sleep rhythm, schoolwork and stress and anxiety of not having performed enough. It was shown that physical activity, diet and regular routines had a stimulating effect in sleep habits.

    Implication: Mental health and sleep habits is something that needs to be shown even more in the future and further research could be more about health promotion. Future research should focus on factors that promote, rather than simply identifying the problem. With the results of this study, the Student Health Care need to work more with the issues of sleep habits and how they could best respond to students with questions about sleep. One example is to introduce compulsory lectures and seminars at universities in order to reach with health information.

    Diabetiska fotsår: Vad påverkar livskvaliteten2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Diabetes is a disease which in many cases leads to various complications, one of them is foot ulcers. Living with diabetic foot ulcers can affect the quality of life, therefore it is important to gain knowledge about what affects the quality of life in order to provide better care and improve well-being. The aim was to highlight aspects that affects the quality of life in people with diabetic foot ulcers. The data collection resulted in 12 articles who responded to the purpose of the study. The examination of the articles was conducted and data was categorized. Five categories emerged which showed that fear, pain, immobility, knowledge and support affected the quality of life among people with diabetic foot ulcers. There was a fear of delayed wound healing, development of new wounds, and for the risk of amputation in the future. Pain from diabetic foot ulcers was perceived as frustrating and was one of the causes of immobility, which in turn created the social isolation. This knowledge was important in order to prevent the occurrence of new foot ulcers so that those affected could seek treatment earlier. In order to manage everyday life, it was therefore important to receive support from different people in the surrounding. The nurse can improve the care and create better quality of life by seeing the person behind the foot ulcer.

    Effektivisera samverkan i BIM-projektering: Kommunikation & BSAB2016Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The definition of BIM has been unclear since the very first beginning and many problems have occurred during the process, which have made the implementation of BIM not completed. Generally BIM can be described as working in 3D with object based tools, which contain massive of information to increase the efficiency information flow during the construction process. The aim for this report is to get a more understanding about the problems designers have encountered, in order to improve the efficiency of BIM design. Since many problems have occurred in the communication process, a Swedish company is making an upgrade of the BSAB-system, to make it more customized with BIM design. This study shows the new BSAB-system can improve the technical problems but it will not solve the social problems. It indicates that the human factor is the key to make the implementation of BIM completed. In order to achieve the goal of implementation, Sweden is in need of a national standard or a waypoint on how to work with BIM designs. The most important of all is the human attitude and the approach of learning.

    Intraarticular vs. extraarticular ropivacaine infusion following high-dose local infiltration analgesia after total knee arthroplasty: a randomized double-blind study2011In: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 82, no 6, p. 692-698Article in journal (Refereed)
    Abstract [en]

    BACKGROUND AND PURPOSE: Ropivacaine infusion following high-volume local infiltration analgesia has been shown to be effective after total knee arthroplasty, but the optimum site of administration of ropivacaine has not been evaluated. We compared the effects of intraarticular and extraarticular adminstration of the local anesthetic for postoperative supplementation of high-volume local infiltration analgesia.

    PATIENTS AND METHODS: In this double-blind study, 36 rheumatic patients aged 51-78 years with physical status ASA 2-3 who were scheduled for total knee arthroplasty were randomized into 2 groups. All patients received wound infiltration at the end of surgery with 300 mg ropivacaine, 30 mg ketorolac, and 0.5 mg epinephrine (total volume 156 mL). A tunneled catheter was randomly placed either extraarticularly or intraarticularly. Continuous infusion of ropivacain (0.5%, 2 mL/h) was started immediately and was maintained during the next 48 h. Pain intensity at rest, on movement, and with mobilization was estimated by the patients and the physiotherapist; rescue morphine consumption was recorded.

    RESULTS: As estimated by the patients, ropivacaine administered intraarticularly did not improve analgesia relative to extraarticular infusion, but improved the first mobilization. The incidence of high intensity of pain (VAS 7-10) was less in the group with intraarticular infusion. Analgesic requirements were similar in the 2 groups (47 mg and 49 mg morphine). No complications of postoperative wound healing were seen and there were no toxic side effects.

    INTERPRETATION: Continuous infusion of ropivacaine intraarticulary did not improve postoperative analgesia at rest relative to extraarticular administration, but it appeared to reduce the incidence of high pain intensity during first exercises, and could therefore be expected to improve mobilization up to 24 h after total knee arthroplasty.

    Abstract [en]

    Work Environment problems at construction worksites are a common topic for discussions. The construction industry is one of the most dangerous industries in Sweden. The industry consists of about 290 000 workers (2009) and the investment was 250 billion SEK. This report will investigate the risks of the work environment and the causes of the fatal accidents.

    The study includes review and analysis of occupational injury statistics, investigation of the occupational accidents made by the work environment authority and interviews. It also includes review of work responsibilities and what type of responsibilities and functions the participant has in the work environment. The result shows that the construction worksites are one of the most dangerous workplaces. The statistics do not reflect reality and important factors are excluded. Work from height and with using machines and tools are the most hazardous types of work. The most common fatal accident is a fall from height. The most common cause of fatal occupational accidents is organizational. Work responsibilities are clear: the employer has the main responsibility for the work environment. The Work Environment Act is the basis for the regulations that Swedish work environment authorities give out. Breaking the law or regulation may not lead to seriously consequences, because it’s a long process before punishment can be divided.

    The issues in the work environment are more extensive in small companies and human error is much due to accidents. Enforcing these laws and giving the inspectors more eligibility than they now have will achieve a better working environment and safer construction sites.

    Caring as sustainable coaching in elite athletics: benefits and challenges2019In: Sport Coaching Review, ISSN 2164-0629Article in journal (Refereed)
    Abstract [en]

    Coaches in elite sport must ensure a balance between performance, high pressure and well-being. A caring approach, based on a coach’s commitment to caring for athletes, has the potential to create such a balance and sustainability. The aim of this study was to identify coaches’ caring and problematise their ethics of care in relation to sustainability. We draw on and integrate the theoretical concept of caring into a conception of (un-) sustainable sport. Semi-structured interviews were conducted with seven Swedish elite athletics coaches. Results show that coaches’ ethics of care is important for creating sustainable elite athletics practices, but that caring also conflicts with sustainability thinking if coaches do not base their actions on practical wisdom and moral and ethical dilemmas.

    Abstract [sv]

    This paper compares and discusses teachers´ nonverbal communication in the classroom. The purpose of the study is to find out what the teachers´ nonverbal communication looks like in the classroom and with that information increase teachers´ awareness of nonverbal communi-cation and its impact on the teaching. Ten teachers at the upper secondary school have been observed for twenty minutes when having a lecture. The result shows that the most common nonverbal expressions are hand and arm gestures used to enhance what is said by the teacher. The result also shows that the nonverbal communication is similar with all observed teachers. Certain theories, like Goffman´s theatrical theory, could explain this by the fact that people step into different roles dependning on what they are doing.

    Achievement Unlocked: En studie i tv-spelsfenomet achievement hunting och dess motivation och gratifikationer2012Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Achievement hunting är ett fenomen som växt fram i tv-spelssammanhang under den nuvarande konsolgenerationen och har fått ett starkt fäste. Idag är det standard att det ingår achievements i de spel som släpps i butik, och det finns spelare som köper spel med motiveringen att det finns lätta achievements att samla. Achievements fungerar i sig som en form av poäng som spelare belönas om de uppfyller ett särskilt krav inom spelet, och därför går det att se achievement hunting som ett virtuellt poängsamlande. Det finns även populära samlingsplatser för dessa spelare på internet där de kommer i kontakt med varandra och spelar tillsammans.

    Detta har fått oss att ställa frågan om det ligger mer bakom achievementjagande än själva spelandet i sig. Kan det vara så att det ligger bakomliggande sociala behov hos dessa spelare? Kan den belöning som spelutvecklarna ger spelaren i form av achievements i sig fungera som en motivation för en annan social belöning som finns bland de communities som omger achievementkulturen?

    Den teori som ligger som grund för vår studie är användarperspektivet (uses and gratifications), och vi har samlat vårt empiriska material genom en netnografisk studie, det vill säga att vi har registrerat oss på tre av de största forumen för achievementjägare och utfört en deltagande observation där vi deltagit i olika diskussioner. Vi har utfört kvalitativa semistrukturerade gruppintervjuer med åtta personer som vi kommit i kontakt med på forumen och genom personliga kontakter. Intervjuerna har bestått av tre grupper varav två stycken har haft tre deltagare och en har haft två, och har skett vid tre olika tillfällen.

    Urvalet för vår undersökning är inte på något sätt representativt, men utefter vår netnografiska studie och våra intervjuer kan vi konstatera att det finns gratifikationer som är anknutna till sociala behov som uppnås via achievementsamlandet.

    BIM-projektering i praktiken2008Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    The use of CAD, within the building industry came strongly, during the 1980’s and the 1990’s. The development has since then rapidly progressed and the using of 3D-models has in addition increased. We are now at the edge of next step of evolution. BIM, Building Information Model(ing), is here. Briefly, BIM is an object oriented 3D-model, which contains information. The information is used in all phases of the building’s lifecycle. BIM simplifies the coordination and enables, among others, a more accurate calculation in an early phase of the process.

    The purpose of the report is to present how BIM applies in practice. The report is based on interviews and observations at the projecting of Halmstad Arena.

    BIM-technology isn’t completely ready yet, but it is on its way. Today BIM is most suited for complex projects. Once you have learned the work method, BIM will be superior the traditional 2D-projecting and applied to every project. New job types will be established, such as BIM-supervisor and building modeler, whom are specialized towards BIM. Even though the objective for all parts has been to work integrated and towards a common objective, with traditional projecting, we aren’t there yet. BIM doesn’t change the objective, but simplifies the approach.

    Abstract [en]

    This bachelor’s degree thesis was conducted in mechanical engineering at Halmstad University during spring semester 2010 in close collaboration with the company Gremo AB, located in Ätran, Sweden. Gremo AB produces, developes and sales forest machines in both Sweden and on the international market.

    Gremo AB belongs to one of the market leaders in forest industry, especially with their forwarder. In order to become a market leader even with their harvester, the company decided to change the harvester to have a swivel and a leveling driver cabin.

    The aim with this bachelor’s degree thesis was to develop a design concept for the harvester driver cabin, which Gremo AB can apply on the new harvester. However, this bachelor’s degree thesis was limited to the outside design of the driver cabin. Further, the aim was to develop a smaller model in order to get a better feeling about the new driver cabin’s appearance.

    By dint of different analysis we developed an edgy driver cabin with shared side posts and a lot of storage space on the outside. Additionally, there are options for more and adjustable lights, which was one of Gremos preferences. Also the inside storage space has become larger with better comfort for the driver. In case of underline our result we developed a smaller prototype.

    The result of this thesis has been passed on to Gremo AB for further development.

    Abstract [en]

    One of the most common ways to detect illness is to measure body temperature. The patient's body temperature is used to determine diagnosis and treatment. The aim of the study was to investigatenurses method for measurement of body temperature andmanagement offever in childrenin thepediatricdepartment. A questionnaire based on previous studies was created.  This questionnaire was used to perform a total survey at a pediatric department in southern Sweden. The questionnaire was formed around four themes; Definition offever, Measurement of body temperature, Assessment of fever andFever-reducingmeasures. The result showedclear variations between the nurses, both in terms of the choiceofwhich measurement instrument to useand procedures fortemperature measurement. How the nurses chose to treat fever also differed between them. The nurses assessed the child's need for antipyretics based on the general condition of the child, but when the nurse felt that the temperature was too high, antipyretics was given. This temperature varied between 38°C-40°C. In Sweden there is no national guidelines about fever management and at the department where the survey was preformed there was not any local guidelines concerning management of fever in children. Guidelines would make it easier for nurses to take consistent decisions regarding the management of fever. This in turn would lead to safer and more evidence-based care for children and the ability to provide good support to their parents. When parents receive good advice and support they feel more confident which will lead to, them being able to manage their child's fever and reduce the need to seek pediatric care.

    Of all registered pregnancies about 20% end in miscarriage. When a nurse meets these women and a potential partner in health care, they have a great need for emotional support. A miscarriage can be a loss of a child that the parents wanted and waited for, the loss involves feelings of sadness, anxiety, helplessness, and sometimes guilt. In the emotionally stressful situation that a miscarriage means parents need emotional support through confirmation, information, and by gaining empathy and understanding from the nurse. The aim of this study was to examine the perceived deficiencies in nursing care after a miscarriage with a focus on emotional support. By examining 11 research articles four themes emerged which revealed shortcomings in the care: deficiencies in interactions, consequences of terminology, deficiencies in communication and lack of follow-up. The shortcomings that emerged in the result means an increase in suffering when parents felt that medical staff diminished their loss and did not see their individual care needs from a holistic perspective. To avoid shortcomings in the emotional support Swanson’s Theory of Care can be implemented as a tool in nursing care. Furthermore, the results indicate a great need for improved skills so that the nurse can be prepared to meet parents who have experienced miscarriage. Through knowledge of the perceived deficiencies, can the nurse in the future be better at identifying and satisfying the emotional needs that arise after a miscarriage.

    SOURCE SPECIFIC FOG DEPOSITION OF BLACK CARBON FROM THE ATMOSPHERE2016Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Black carbon (BC) plays an important part in global climate change. In addition, long term exposure to BC is closely related to pulmonary and cardiovascular mortality. BC is formed by the incomplete combustion of carbonaceous compounds. In urban environments the main sources come from the burning of biomass for domestic heating and diesel vehicles. The typical lifespan of airborne BC is about a week and is treated as a short-lived climate pollutant. Wet deposition, which is more significant closer to the source, is the primary deposition mechanism and condensation of water is dependent on the sources of BC. Measurements with aethalometers determine the sources of BC concentrations, particularly fossil fuel combustion from traffic (ff) and wood smoke (bb).

     

    The in-situ measurements in this study reveal that the different source apportionment of BC emissions with different initial properties of BC behaves differently during the fog periods. Foggy periods from the March and January 2015 data set were carefully collected. In January, the fog occurred throughout the entire observation time, while in March the fog occurred for different durations, from 1 to 7 hours. A linear regression between the normalized BC, BCbb, BCff concentrations and 7-hour periods at night was calculated for each individual period. The comparison of slope values (k), standard errors and p-values of different sources of specific BC emissions was then made. Despite there not being a great difference between the slope values of BCbb and BCff in the January data set, the results revealed that BC emissions from biomass burning have fewer non-statistically significant values than the BC emissions from vehicle exhaust. This study corresponds to the different initial properties of fresh aerosols from both sources and indicated an increased fog deposition of BC from biomass burning.

    Den Frivilliga återvandringen i Sverige, en studie baserad på intervjuer.2010Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    What is the government mandate Voluntary repatriation about? That was the question we asked ourselves during the report's time. Using a qualitative approach in the form of semi-structured interviews was the hope to understand the Government mission and its purpose in Swedish society. Through concepts such as segregation, stigmatization, rationality, solidarity and the relational and punctuate perspectives we have gained an appreciation for the immigrant's problem of adaptation in Swedish society, in which we can experience problems when immigrants have difficulty getting the support he needs to take a decision on issues that remain or repatriate. We have also chosen to deal with Foucault's concept of the disciplining power of the State and society complicates the decision immigrant faces. In this way, it was shown that the immigrant repatriation concerns with living in a complex situation where both societies makes it difficult and that his thoughts are not legitimate, and that the government mandate is added as a pre-taking that decision regardless of what decision then becomes, to stay or return.

    Ocean acidification effects on marine organisms: a study of Littorina littorea and Balanus improvisus 2011Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The world’s oceans are becoming more acid in a process called ocean acidification. The pH of the ocean have already decreased by 0.1 units from pre-industrial time until today. Scientists predict that by the year of 2100 the pH will decrease by as much as 0.4 units. This is a big potential problem to many marine species, because they have developed in such a stable environment that has not changed for millions of years. It is difficult to predict how they might be affected by such a decrease in pH during a relatively short time period. Several studies have been made on marine species exposed to decreased pH-levels, the results showed changes in their physiology but it is hard to predict how these changes will affect the organism in a long-term scale and if this might change ecosystem dynamics. Our study measured the activity of Littorina littorea and Balanus improvisus when exposed to lower pH, the results of our study showed an increase in activity for the lower pH (pH 6.0-7.5) when compared to the control (~pH8). The area of ocean acidification is a field that requires further studies to fully understand its effects on the marine ecosystems and the species within it.

    Varför Jehovas vittnen?2008Independent thesis Basic level (degree of Bachelor)Student thesis
    Abstract [sv]

    Jag har valt att göra en kvalitativ undersökning som består av intervjuer med medlemmar i Jehovas vittnen, icke medlemmar samt avhoppare. Syftet med denna undersökning är att ta reda på vilka faktorer det är som bidrar till att människor väljer att ansluta sig till Jehovas vittnen. För att få en bredare bild av Jehovas vittnes organisation har jag valt att även utföra tre intervjuer med avhoppare. Intervjuerna med Jehovas vittnen utfördes gruppvis på Rikets sal i Halmstad medan intervjuerna med övriga respondenter som icke är Jehovas vittnes utfördes i hemmet eller på arbetsplatsen. Intervjuerna med avhopparna skedde till via mail och telefon. Jag kommer att ta upp respondenternas sätt att resonera kring valet de har gjort och även ta upp vad och hur icke vittnena resonerar om Jehovas vittnen. Avhopparnas´intervjuer belyser ytterligare hur organisationen inom Jehovas vittnen fungerar samt hur de hade det under tiden som vittnen. Uppsatsen kommer att belysa hur Jehovas vittnen resonerar kring valet att vara Jehovas vittne. Jag får ta del av deras synsätt om hur det är att leva i ett samfund som Jehovas vittnen. Jag

    kommer även att presentera och diskutera de tankar som icke vittnen har om Jehovas vitten samt avhopparnas syn på organisationen. Efter den sociologiska analysen följer en slutdiskussion.
