Resurseffektivisering vid värmebehandlingsprocesser
Vid tillverkningen av drivlinekomponenter är värmebehandlingsprocessen en process som står för en stor del av tillverkningens resursförbrukning. Med framtida stigande el- och propanpriser är det viktigt för industrin att identifiera möjligheter till energieffektivisering samt minska den egna resursförbrukningen. En minskning medför lägre kostnader och bättre miljö samtidigt som företaget bibehåller sin konkurrensförmåga. Arbetet har utförts vid Volvo CE Component Division AB i Eskilstuna och syftade till att kartlägga värmebehandlingsprocessen sätthärdning och att lyfta fram potentiella förslag till återanvändning av spillvärme. Utöver kartläggningen genomfördes även en benchmarkingstudie för att belysa hur arbete kring resurseffektivisering sker inom andra företag med värmebehandling och hos leverantörer av ugnsutrustning.
Maktdelning : och konstitutionellt rättighetsskydd
The topic of this master thesis in legal science is state law and constitutional law, or more specific judicalization, with the division of power and thus increased individual legal rights in various forms. Sweden has traditionally had a weak constitutional protection for the individual?s legal rights. The public power has been concentrated to the government and the courts have only played a marginal role. Since the implementation of the European convention of legal rights and with the ever-increasing importance of the legal system of the European Union, the Swedish legal system gone through changes of historical dimensions.This master thesis is based on the legal dogmatic method where laws, preparatory work, case law and doctrines have been systemized.
Examining the social component of sustainable forest management in Prince Albert and Vilhelmina Model Forests
Due to the forest industry downsizing, many communities in rural forest regions in Canada
and Sweden are facing problems to survive. In order to create community sustainability,
resilience and well-being in remote forest regions, the view on the forest resources has
shifted towards multiple use, through the concept of sustainable forest management (SFM).
Beside the economic and ecological elements of sustainability, the social forest values are
needed, contributing to the human well-being, local participation, stakeholder collaboration,
human rights and cultural connection.
In this thesis the embodiment of the social component of SFM within Prince Albert Model
Forest (Canada), and Vilhelmina Model Forest (Sweden) will be examined. Being partners
and facing similar challenges as rural boreal forest regions, the two model forests are compared
through analysis of projects and activities, conducted interviews and organization
documents.
Looking at projects mentioned as successful by the interviewees, they all have elements
from the social values of SFM. The direction can be explained by the introduction of the
Forest Communities Program in Canada, demanding the Model Forests to work towards
community stability and resilience, the Model Forest organization concept itself and the
way global focus are increasing around social forest values. In the future, it may be important
that the role of the MFs enable some kind of political authorization and legitimacy in
order to improve conflict solving and indigenous rights equality.
Organisation på ridskola
Organizations are about people in interaction. Human itself is complex, and the complexity increases when people are grouped. When creating groups there is a need for a structure, an order between the people in the group. Companies have an organization - riding school is also a company and should have an organization. Many studies have been done related to the riding school but there is no documentation about organizations at riding schools, and a research is needed.
The aim of the study was to clarify if riding schools in Sweden has a well considered organization.
Production system mapping for product design
Detta examensarbete är resultatet av en utredning av produktionsbegränsningar och produktutveckling på Volvo Construction Equipment AB Component Division i Eskilstuna. Produktionssystemet på Volvo CE genomgår en stor förändring då det går från att fungera som en funktionell verkstad till att bli flödesinriktat. Detta gör att helt nya krav ställs på produkternas konstruktion och utformning. Det är nu inte möjligt att anpassa maskinerna eller operationsföljderna efter artikeln i samma utsträckning som tidigare, man kommer att vara tvungen att anpassa artiklarna efter produktionslinan. Därav har en litteraturstudie inom Concurrent Engineering gjorts som belyser hur man bör jobba som organisation och vilka verktyg man har till sitt förfogande, för att utveckla produktionsvänliga produkter.
Konstruktion Signalgenerator
SAAB Aerotech division FGR in Arboga builds and develops equipment and components used in both military and civilian applications. To build a test system for a specific project that SAAB is responsible for requires a simple signal generator that can provide a pulse modulated signal. The need to buy a new advanced signal generator for example from Agilent is not as profitable as the instrument is expensive and contains features that SAAB does not require in their applications and test systems. That was the reason why SAAB offers two students a thesis where the goal is to construct a signal generator in accordance with what SAAB requests.This thesis contains several different phases. The first step was a meeting with our supervisor Mats Bergman and by reading the data sheets for components to be used in the project, with these information and specifications that we have received from SAAB we started to construct the signal generator.What we did during the construction work was to simulate and draw a schematic to be able to design the circuit board.
Karaktärisering av höstvetets avkastningskomponenter
Wheat yield depends on the number of ears per m2, the number of kernels per ear and the kernel weight. By knowing the ability of different cultivars to compensate for the different yield components and knowing which yield component that is the most important for the final yield, the farmer can match the cultivar and management to the location. The objective of the study was to investigate how the yield components of winter wheat vary depending on genotype, environment, sowing density and date of sowing.Seven varieties were grown in four locations in Sweden with three different sowing densities and with an early and a late sowing date. On each experimental site, the surviving plants after winter were counted, as well as the number of shoots at early and late spring and the number of ears. Ten ears from each site were cut at three different occasions, starting from the time of blooming, with 200 day degrees between each cut.
Dämpning av ljud i Shift-by-Wire växelväljare : Noise damping in a Shift-by-Wire gear shifter
Constantly growing demands from the costumers in the Automotive industry forces the subcontractors to seek alternative ways to compete. One parameter of quality is the components tolerance against NVH(Noise, Vibraion & Harshness) aspects. Kongsbergs Automotive has developed a new gear shifter platform (Shift-by-Wire) that is sold to Alfa Romeo and used in of their car models. However, the company is not pleased with the components sound quality, therefore the main purpose of this thesis is to develope a number of concepts that is supposed to enhance these NVH-aspects.To get an understanding of the problem an analysis of the causes of the emitted sound has been done parallell to a product decomposition, function decomposition and a Ishikawa-diagram. Together with these methods has a litterature study been performed to get familiar with the physics of an impact and especially the emittment of noise.
Klassifikation och definition av socialantropologi En jämförande studie ur ett hermeneutiskt perspektiv
The purpose of this thesis is to study the relationship between the definition and bibliographical classification of a certain academic subject; social anthropology. The theoretical framework consists of views held in Information Science regarding the definition and classification of subjects. The methodological onset is based on hermeneutical concepts that allow an extended analysis of abstract structures of thought. This analysis comprises of two parts; a descriptive analysis and a comparative analysis. The result of the descriptive analysis, whose aim is to describe the academic subject social anthropology, shows that this is not easy to define, instead it is nowadays almost the same as cultural anthropology.
Brott eller norm? : En kvalitativ studie med ett genusperspektiv på mäns fysiska handlingar inom fotbollen
I denna studie har fokus legat på mäns handlingar inom sporten fotboll. Definitionen på begreppet handling har i undersökningen syftat enbart till fysiska handlingar som vid för grov användning skulle kunna leda till brott, t.ex. misshandel. Centralt i undersökningen har varit att ta reda på hur intervjudeltagarna beskriver var gränsen mellan aggressivitet och våld går, samt se varför spelare handlar på ett visst sätt i match- och träningssituationer. Frågeställningarna studien utgått ifrån är:Varför handlar manliga spelare på ett visst sätt i match- och träningssituationer?Hur definierar de skillnaden på att vara aggressiv och att vara våldsam?Undersökningen utgår från ett socialkontruktionistiskt perspektiv, där genusteori står i fokus.

This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.
Konvertering från luft till vätskekylning av elektronik
A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

The application is used today with complete success at the Department of Computer and Information Science at Linköping University..
Manliga fotbollspelares maxstyrkedifferens mellan dominant och ickedominant ben : En jämförande studie
Skillnaden i muskelstyrka mellan dominant och ickedominant ben hos fotbollspelare hartidigare studerats. Det finns inget enhälligt resultat om vilket ben som är starkast eller om detalls föreligger någon skillnad. Tidigare forskning har utfört mätningarna i sittandeutgångsposition vilket inte stämmer överens med fotbollspelares huvudsakliga aktivitet. Syftetmed uppsatsen var att, hos en grupp fotbollspelare i division ett och två, beskriva och jämföraden maximala muskelstyrkan mellan dominant och ickedominant ben. Datainsamlingenutfördes i en liggande utgångsposition då detta ger liknande muskellängdsförhållandet somvid stående.
Individuell utprovning av inkontinenshjälpmedel i kommunala särskilda boenden
The purpose of this study was to examine the extent to which incontinence aids, used in local authority/municipal nursing homes, were adapted to the resident?s urine-leakage volume and to find out how nurses perceived the current situation concerning individual testing of incontinence aids in municipal nursing homes. The study method was a quantitative empirical study and was carried out in two phases. The first phase was a weighing test, carried out in three nursing homes, whereby the incontinence aids used by 25 residents during a 48 hour period were weighed. The second phase was the completion of a questionnaire by the municipal nurses working in the same local authority.
