Scanias nuvarande mjukvaruprocess upplevs, i många fall, vara onödigt lång från det att en idé har genererats tills att den har lanserats på marknaden. För att konkurrera på marknaden är det viktigt att erbjuda nya tjänster och ny avancerad fordonsstyrning som snabbt ska kunna sättas i produktion. För att säkerställa att mjukvaran uppfyller de uppsatta kvalitet- och säkerhetskraven används inarbetade processer däribland den så kalladeEmbedded Release Process. Dock är denna process inte alltid till hjälp för utvecklingen och kan medföra lång "time-to-market".Syftet med detta examensarbete var att utreda Scanias nuvarande utvecklingsprocess av mjukvara med avseende på ledtider, eftersom det idag råder frågetecken om huruvida processen är tidsmässigt optimerad från idé tills att den når kund.De metoder som har använts för att angripa de uppställda frågeställningarna har bestått mestadels av kvalitativa forskningsmetoder så som litteraturstudie, värdeflödesanalys, fallstudie, benchmarking samt workshop. Såsom ett komplement till den kvalitativa forskningen har statistik tillämpats i fallstudien.Värdeflödesanalysen visade på många överlämningar inom organisationen, centraliserad beslutsfattning samt att flödet sker sekventiellt.

Fruit flies (Tephritidae) are serious pests that cause enormous losses for farmers in many countries. The frequent use of insecticides in controlling fruit flies in fruits and vegetable has not resulted in sustainable management of the pest. Problems associated with this complete reliance on chemical control are many residues of insecticides in crops, health problems for farmers, contamination of water and soil, insecticide resistance development and decrease in natural enemy populations. The implementation of control measures that do not imply an added burden to the environment and/or the farmers is urgent. More knowledge about the ecology of fruit flies is the basis for finding new and better ways to control this pest.

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.

The “peer to peer” (P2P) is a technology of downloading and filesharing between online - Internet - users by the mean of specified software. Since June 1999, the Napster software has made the happiness of millions of individuals who used it to obtain and share free audio files Mp3. Rapidly, the major recording companies have prosecuted the Napster Company and managed to force it to close down. They were arguing against it for it is supporting the development on a large scale traffic of files protected by copyright and thus was threatening the whole music and movies economic world. Since fast Internet connections multiplied, "peer to peer" software and networks improved, so that this mode of exchange became an unprecedented success. Today all cultural products, in particular films and music, are concerned with this free –of– charge distribution without any financial counterpart for the copyright holders. Two tools hold today the top ranks and concentrate large traffic: eDonkey and eMule.

Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.

More than 1000 Swedish Warmblood foals are shown every year at foal inspections which are arranged around the country. Six traits are evaluated at these inspections: type, head-neck-body, correctness of legs, walk, trot and canter. No previous genetic studies have been done on the data from these evaluations. The purpose of this study was to do genetic analyses of the traits which are evaluated at foal inspections. The purpose was also to see if there are any correlations between the results of the foal inspections and the results from the tests of three-year-old horses.

Background: Sporting events conveyed by the TV medium affect people and can give many unforgettable experiences. Sport may be synonymous with excitement and drama or just serve as entertainment. Through TV broadcasts from different sporting events, millions of televiewers all over the world have enjoyed athletic feats of extreme top class. TV broadcast sport always attracts a great number of viewers, also in Sweden. The prices of broadcasting rights to sporting events have risen strongly during the last decade, much as a consequence of the increasing competition between different TV companies both internationally and in Sweden.

Hammarby Sjöstad is a new district in southern Stockholm. A main objective with the Sjöstad project was to halve the environmental impact compared to other construction work. The environmental goals involve a halved water consumption rate, a local treatment of storm water and trials aiming to extract nutrients from the waste water. Sjöstadsverket is an experimental treatment plant used for testing new treatment processes for domestic waste water from Hammarby Sjöstad. The results are to be compared with the conventional process used at Henrikdals treatment plant today.

Energy is an essential part of the society and for a sustainable future we need to use the energy resources in a sustainable way. The forest is Sweden?s most important resource for renewable energy and a higher production combined with shorter rotation periods (time from planting to clear cutting) can increase the access to energy. The tree genus poplar (Populus spp.) is interesting as energy resource as it has both high production and short rotation period. But browsing ungulates are a major threat to the establishment of poplar plants and therefore the poplar plantations need to be fenced in today. To use fences is expensive and time consuming; this makes it interesting to find more cost-effective solutions where there is no need to fence. The aim with this study was to look at the ungulates? occupation rate and browsing pressure in poplar plantations without fence.

När en grupp utvecklare jobbar med samma kodbas kan konflikter uppstå med avseende på implementationen av moduler eller delsystem som varje utvecklare individuellt jobbar på. Dessa konflikter måste snabbt lösas för att projektet ska fortskrida och inte stagnera. Utvecklare som sällan kommunicerar framför ofta okompatibla moduler eller delsystem som kan vara svåra eller omöjliga att integrera i kodbasen, detta leder ofta till s.k. ?integration hell? där det kan ta väldigt lång tid att anpassa ny kod till en befintlig kodbas. En strategi som man kan ta till är ?continuous integration?, ett arbetssätt som erbjuder en rad fördelar när man jobbar i grupp på en gemensam kodbas.

Den teoretiska delen innebar informationssökning inom olika medier, såsom vetenskapliga artiklar och intervjuer med insatta människor inom de berörda områdena. Den praktiska delen i examensarbetet bestod av flera olika moment.

Uppsatsen berör fältet med självhjälpsböcker om dejting och vilken verkan dessa kan ha på bilden av hur man och kvinna ska vara i samhället. Syftet med uppsatsen begränsar sig till att, genom en topikanalys utifrån Ciceros och Janne Lindqvist Grindes persontopiker, göra en jämförelse av könsrollernas framställning i Henrik Fexeus dejtingbok Alla får Ligga - Strategier i förförelsekonst för den moderna gentlemannen och kvinnan, och Sara Starkströms dejtingbok Game Girl. Det görs genom att genus läggs på dessa topiker som funnits intressanta. I analysen används Yvonne Hirdmans genusteori om genussystem och genuskontrakt för detta ändamål.Tidigare studier i ämnet som är intressanta för studien är bl.a. Panteá Farvid & Virginia Brauns artikel ?The ?Sassy? Woman and the ?Performing? Man: Heterosexual Casual Sex Advice and the (re)constitution of Gendered Subjectivities?, och Leto DeFrancisco och Penny O?Conners intressanta inlägg ?A feminist critique of self-help books on heterosexual romance: Read ?Em and Weep?.

Since the first wolf was taken as a companion animal a lot have happened with the biology of these animals. Is it possible that changes in the gut microbiota of the domestic dog are involved in the increasing numbers of animals with gastrointestinal disorders? Probiotics have been proven to promote the immune system of dogs by increasing concentrations of neutrophils and monocytes, decreasing the fragility of erythrocytes and increasing the serum IgG concentrations. Probiotics have also been shown to improve the fecal consistency, fecal dry matter and defecation frequency of dogs. The aim of this study was to find out if the bacterial counts in the gut of dogs differed from the gut of wolves, with the focus on lactobacilli.

With the advance of the modern information society, the importance of reliable identity authentication has increased dramatically. Using biometrics as a means for verifying the identity of a person increases both the security and the convenience of the systems. By using yourself to verify your identity such risks as lost keys and misplaced passwords are removed and by virtue of this, convenience is also increased. The most mature and well-developed biometric technique is fingerprint recognition. Fingerprints are unique for each individual and they do not change over time, which is very desirable in this application.
