TCP (Transmission Control Protocol) is a transport protocol designed for the wired Internet. In wireless networks packet losses occur more frequently due to the unreliability of the physical link. The main problem is that TCP treats all losses as congestion, which leads to a lower throughput. Ad hoc networks are multihop wireless networks of mobile nodes, where each node can allow other packets to pass through it. Topology changes often occur and may lead to packet losses and delays, which TCP misinterprets as congestion.

Varje dag begås misstag utav människor. För piloter kan dessa misstag bli fatala. Länge har man vid flygolyckor endast sett till de direkta misstag som blivit begångna och på så sätt skaffat sig en syndabock. I detta arbete kan dock vikten av att uppmärksamma faktorer som varit bakomliggande i organisationen påvisas. Då en olycka inträffar skiljer man mellan osäkra handlingar och latenta förhållanden.

The purpose of this study is to examine some factors that make a human grouse hunter to prolong and increase its hunting effort. The theory of optimal foraging is used for explaining their behavior.The data of this study is collected from a web-based inquiry from 2007 answered by grouse hunters in Sweden. The method that has been used is mainly bivariate statistics and logistic regression analysis.Key findings shows that an experienced grouse hunter has more than 5 times the chance of prolonging hunting effort when grouse density is high, compared to a beginner grouse hunter. On the same time experienced grouse hunters also stop hunting in advance when grouse density is low to a larger extent than inexperienced hunters. Other factors of importance for prolonging the hunting effort for a day are age and the travel distance to the hunting area.

Syftet med detta arbete är att försöka utforma en modell för att analysera olika matavfallssystem. Detta arbete görs med skärskilt Kiruna kommun i tanke då detta arbete är en del i en önskan från deras sida gentemot Luleå tekniska universitet. För att göra en analys så byggs en systemanalysmodell utifrån vilka alternativ som är intressanta att studera i det här fallet brännbart, en hybrid lösning, kärlinsamling för rötning och köksavfallskvarn. Dessa alternativ valdes sedan att utvärderas gentemot ett antal parametrar inom områdena användaraspekter, transport, process och slutavsättning, energi och säkerhet. Dessa parametrar ska sedan utvärderas och poängsättas.

This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

Syftet med denna studie är att undersöka hur etisk produktion påverkar konsumenters attityd gentemot en ökad investering vid konsumtion. Vedertagen teori menar på att etisk produktion har en positiv påverkan på den genomsnittlige konsumentens attityd och att konsumenter kan tänka sig att betala ett högre pris för produkter producerade på etiskt vis. Med syfte att konkretisera begreppet CSR och underlätta för respondenterna i enkätundersökningen används begreppet etisk produktion med hänvisning till äggkonsumtion. Aspekterna av begreppet etisk produktion som ligger till grund för denna studie är miljövänlig transport och god hönshållning. Studiens resultat redogör för att konsumenter är positivt inställda till att betala ett högre pris för produkter producerade på ett etiskt vis och att etisk produktion är ett produktattribut som påverkar konsumenternas attityd gentemot konsumtion..

This bachelor of economics paper discuss that the increasing globalization has put the small companies in the Swedish textile and clothing industry in a situation where internationalization has become a necessity. Furthermore has the European Union lead to that this type of companies has to seek growth on foreign markets with great socio cultural distance from the home country, Sweden. Nowadays there?s no time to internationalize in the same course of action like before. Before, the Swedish companies begun their operations abroad in fairly nearby countries and only gradually penetrated more far-flung markets.

The purpose of this article is to explore the technologies of government that are created within gender disorder assessments as an institution. I have done so by utilizing Norman Faircloughs discourse analysing instrument ?communicative action?, which focus on the social institution as relational.The material is strategically chosen by gathering texts from the Swedish state, the psychiatric clinics, NGO:s and by performing interviews with transsexual patients.When analysing the communication of the main agents, I have concluded that practices highly are a result of repeating text and speech inside the institution. The psychiatric assessments can also be seen as an illustration in changes in how citizens are governed in advanced liberal societies, where the role of the state has been gradually reduced in favour of other agents.I consider that the change illustrates an ?acting at a distance?-mentality where the patient is introduced to participate in the definition of the care in what I call ?negotiation as a technology?.

This examination report is a part of a program for Industrial organisation and Economics with specialization in Logistics and Management at Jönköping University. The report contains an analysis of the internal material handling at Kongsberg Automotive, and also an improvement proposal for a new material handling system.The aim with the report is to find a better material handling system and also make an analyse of the existing system. The goal is to shorten the distance for the operators when they order material, and also to increase the productivity.The investigation methods for the report have for the most part consisted of observations and interviews of key-persons who daily work in the production. During some time the actual material handling-system has been observed and some shortcomings have been discovered, and these are also discussed in the report.The shortcomings that have been discovered are for once the indistinct signal that should signal need of material in the production. Some other activities have also been discovered that does not bring any value into the final products.

At the beginning of the nineties, a new form of organisation, the process organisation, was about to be born. The features of the process organisation were a flexible organisational that works in a world where the pace of development is increasing all the time. Today there are many organisations that have mapped their processes, but in order to truly become a process organisation, the processes among other things have to be in harmony with e.g. organisational culture. Which effects the organisational culture has on the process organisation is yet unexplored, but however quite crucial.

Bakgrund: I Sverige drabbas cirka 30 000 personer av stroke varje år. Stroke är ett samlingsnamn för hjärnskador orsakade av blödning eller infarkt i hjärnan. Stroke uppenbarar sig som en plötslig förlust av kroppsfunktion som styrs av hjärnan. En genomsnittlig strokepatient förlorar nästan två miljoner neuroner, 14 miljarder synapser och 12 km myeliniserade nervfibrer varje minut som stroken är obehandlad. För dessa patienter krävs det en snabb handläggning och snabba insatser för att minimera de hjärnskador som uppstår.

The purpose of this master thesis is to examine how librarians/cultural workers act in projects in order to stimulate and promote reading among children and youth in sparsely populated regions in the county of Jämtland during a period of three years, and if/how these projects differ. The examination is based upon the progress of these projects in four of eight communities. Four librarians and two cultural workers have been interviewed in order to get their view of the proceedings of the projects. The results indicate that the four communities all made up plans for three years but in different ways. They mainly collaborated with the school but also with the board of children's health and the preparatory school.

This work aims to improve our knowledge about Swedish video game journalists, a new occupation in a quickly expanding business. Through a survey sent out to over 50 Swedish video game journalists, the result indicate some unexpected facts. Men largely dominate the profession; just 10 % of the work forces are females. This relation was notable in our survey, as well as in earlier studies. Video game journalists between 26 and 35 years old seems to be the largest age group, which we think is a bit surprising considering how new this form of journalism is, and the fact the internet provides opportunities for every enthusiastic video game writer.

Stereotypic pacing is frequently observed in captive carnivores, however the underlying causes of this behaviour remain somewhat unclear. One of these possible causes are unpredictable feeding signals, which may give rise to frustration and subsequent pacing. Animal keepers at Nordens Ark had noticed that their Amur leopards had shown stereotypic pacing in connection to the passing of ATVs (All Terrain Vehicles) used by animal keepers primarly when feeding the animals in the park. The aim of this study was to investigate whether the stereotypic pacing of the two Amur leopards at Nordens Ark were affected by the introduction of a signal associated with feeding. The leopards were trained by classical conditioning to associate the sound of a siren with the delivery of food by an animal keeper.
