Kravspecifikation för en knapp till ett automatväxlingskoncept

This thesis deals with the development of a specification regarding a push-button, which will be used to control the gear-shifting function in an automobile. In addition to this the author will describe different techniques and theories that have been helpful in achieving data and results for the specification.Kongsberg Automotive AB, is located in Mullsjö, Sweden, the company supplies parts to the automotive industry. In the research and development department, R&D, there is a group that works with development of Shift-By-Wire systems. In an automobile with a Shift-By-Wire system the communication between the gear-shifter and the gear-box occurs electronically. The mechanical link is, in most cases, taken away and replaced by the digital system.

This study discloses Swedish human service organizations and their methods of integrating unaccompanied children into the Swedish society. The purpose of the study is to investigate how social workers at HVB-homes for unaccompanied children depict their experience in and knowledge of how the unaccompanied children are integrated into Swedish society. The method of investigating the questions raised by the purpose of this thesis has been qualitative analysis of answers derived from interviewing personnel at HVB-homes for unaccompanied children. In doing so we have made use of a semi-structured method of interviewing the above-mentioned personnel. The data derived from these interviews has thereafter been analysed and filtered through the concept of integration and the theoretical formations human service organizations and street-level bureaucrats.

Utveckling av högspänningskontakt

This report describes the development of a high-voltage connector at the request of Scandinova Systems AB in Uppsala. The development process is described from the making of a customer demand specification, to the making of drawings for the manufacturing of prototypes. Scandinova develops high-voltage modulators, hence the need for connectors that can handle very large power pulses. Their current connector has several weaknesses that may cause the connector to melt or catch fire. The development began with a number of studies that included the modulator structure and the current connector structure and functions.

Dynamisk analys och utmattningskontroll med hjälp av fältmätningar och FEM : Fallstudie över SL:s Bro norr om Söderströmsbron

AbstractThe project "Sound and Play" have been implemented in collaboration with the toy company BRIO in Malmo. The purpose of the project was to examine whether and how BRIO in the future could develop toys around sound for Toddlers.The problem formulations that would be answered after completion of the project was "How could BRIO broaden its product range with the help of audio toys?", "How can you combine toys and sounds in an interesting way for children?", "How do you create a toy with sound that is fun for the child, but not annoying for parents?". Currently BRIO only has two toys with sound in this age group.The expression of the toy was going to be a mix of classic and cool and the overall feeling of the toy was going to be explorative and arouse curiosity in the child. This feeling would be communicated through simplicity and joy.

Positionering - En etnisk identitet som föds?

This study is a qualitative study based on a constructivist approach. Meanwhile, it draws on an ethnographic approach combined a working memory based on memories in various events that took place three years in a former student in the program for sociology and social development. Mainly qualitative interviews are essential for the empirical material analyzed. The study is based on interviews of five college students with an ethnic origin other than swedish at Halmstad University, four women and one man. The aim is to look at how college students with an ethnic origin other than swedish relate to the representations of ethnicity.

Konstruktion av formkropp pa JAS 39 E/F Gripen

The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.

Biogaspotential hos våtmarksgräs

BIOGAS POTENTIAL IN GRASSES FROM WETLANDSMarvin MartinsThe purpose of this study has been to survey wetlands that are suitable for mowing and to analyze the biogas potential in the harvested grasses. A preformed investigation showed that there are suitable wetlands, which can be harvestable, namely those mowed formerly in traditional haymaking. The practice of traditional haymaking is dying out in Sweden today but there are several good reasons why it should to be reconsidered. Nature- and cultural values are obvious, also the unutilized energy in the grass.The suitable types of wetland that were specifically studied were the productive wetlands; meadow marshes and wet meadows. These wetlands are represented in the Swedish meadow- and pasture inventory database; (TUVA) and the Swedish national wetland inventory (VMI).

Han, hon eller hen? : - En kvalitativ studie om pedagogers förhållningssätt , jämställdhetsarbete och bemötande i förskolan i Karlskrona kommun och Markaryd kommun

Syftet med detta examensarbetet var att ta reda på och jämföra hur pedagoger i förskolan arbetar med jämställdhet och begreppet "hen", samt hur barnen bemöts och om det finns skillnader härledande till barnens kön. För att studera detta användes de kvalitativa metoderna, observationer och intervjuer. Här jämförs Karlskronakommun och Markarydkommun genom fyra observationer och 13 intervjuer med pedagoger och förskolechef. I studien framkom det att pedagogerna vet vad jämställdhet är och menar att de bemöter barnen lika oberoende av kön. Men omedvetet stimulerar pedagogerna de traditionella könsmönstren istället för att motverka dem.

Träbroar för järnvägstrafik

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Kroppens harmoni : om relationalitet i G.W Leibnizs monadologi

The purpose of this essay is to discuss relationality in G.W Leibnizs Monadologie (1714). In general terms this essay analyzes the notion of individuation in relation to the concept of monads. The analysis proposes a question regarding the body in this individuation, and what consequences follows for the understanding of the relation between the single individual and other individuals. It will be shown that the irreducibility of having a body transcendens something like ownness, subjectivity, personality and individuation, and this is explained through the pre-established harmony between the monads ? where the plurality of monads is detected before the monads singularity. To widen this investigation of relationality between the monads, I will turn to Edmund Husserls phenomenological operation for solving the egological problem of solipsism in Cartesian Meditations (1929). In his meditations, Husserl uses the monad as a self-conscious ego with peculiar ownness.

Gender, labor and decision-making : the woman?s situation in family businesses in a Swedish agricultural setting

The inequality and separation of sexes seen in organizations may lead to inefficient use of human resources. Therefor, a more equal organization could lead to higher productivity and efficiency. Inequality within organizations is a problem also for the society as a whole since who is chosen for a position is not depended upon merits, leading to inefficiency. To not reflect upon traditional division of labor and decision-making could also lead to an undemocratic and unjust society. The aim of this thesis is to explore women and men?s engagement a family business in an agricultural setting. Gender theorists argue that gender arises from the social situation in society.

Automatisk lockmekanism : från idé till prototyp

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

IFRIC 15 : och dess påverkan på byggföretagens intäktsredovisning

The number of studies on IFRIC 15 is very limited. The available studies have either been conducted before the introduction of IFRIC 15 or at an early stage of the implementation. This study examines IFRIC 15s practice from a longer perspective. The purpose of this study is to explain the effect that the interpretation IFRIC 15 has had on accounting objectives and qualitative characteristics of the revenue recognition of Swedish construction companies. The study will also analyze whether the construction companies has changed their perception of IFRIC 15 after applying it form a longer time perspective.

Kombinationsträningseffekter på fysiologiska egenskaper relevanta för handbollsprestation på elitnivå. : En experimentell interventionsstudie på manliga elithandbollsspelare under tävlingssäsong.

Syfte och frågeställningar: Syftet med denna studie var att undersöka de fysiologiska effekterna av kombinationsträning, innefattande styrketräning, contrast complex training (CCT) kombinerat med intervallträning i form av upprepade kortare sprintar (ca 6 s) (RSE) eller längre (30 s) högintensiva intervaller (HIIT) hos handbollsspelare i herrelit, under tävlingssäsong.Metod: Under 12 veckor, i tävlingssäsong, genomförde 15 elithandbollsherrar, utöver sin vanliga handbollsträning antingen RSE (n=8) bestående av 10 repetitioner av shuttle sprintar (2 x 15 m) med start varje minut och med passiv vila eller HIIT (n=7) bestående av 5 reps av 30-s all-out sprintar med riktningsförändringar. Båda grupperna genomförde ocksåCCT bestående av 3 set med 3 övningar (3 x knäböj 90 % av 1RM, 6 x jump squat med 50 % av kroppsvikten, 6 x dropp jump från 30 cm Pre- och posttesterna inkluderade jump squat (JS) (RFD (Ns/kg)), 5 jump for distance test (5JT) (m), 30m sprint (5m (s), 20-30m (m/s), repeated shuttle sprint ability test (RSSA) (RSA Bäst, Sämst, Tot (s) samt beräknat trötthetindexFI (%), Sdec (%)), 1 RM knäböj (koncentrisk) (kg/kg kroppsvikt), Yo-Yo intermittent recovery test (YYIRT 1)(m) and maximal syreupptagningstest (VO2max) (l O2/min, ml·kg-0.75·min-1). Resultat: Båda grupperna ökade signifikant maxstyrkan i knäböj, RSE gruppen (8,8 %) mer än HITT (7,4 %) (p<0.01). I motsats visade HIIT gruppen större förbättringar i rate of force development (RFD) (63,3 %) än RSE (56,3 %) (p<0,05). VO2max ökade signifikant och likartat i båda grupperna (~2%).
