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.

This study attempts to examine the existence and development of price differences in the car sector in Europe. The time period is between 1995, the year of the Swedish entrance in the European Union, and 2003. The study is based on data supplied by the European commission, on a bi-annual basis. Both price differences in general in the EU, and price differences between Sweden and other countries in the EU are examined. The theoretical law of one price is related to the economic integration of the EU and the car sector.

Piled friction soil show a set-up which is increasing with the time after installation. The cost could be reduced if the set-up had been taken into account when designing but in Sweden it is very unusual to do that. Previous studies showed that set-up can vary between 25 % and 75 % during the first 90 days after pile installation. This showed that the effect of the phenomenon is difficult to predict. A study involving five projects have been carried out by specifying certain parameters like pile type, method for pile installation and test method for measure the bearing capacity in friction soils located in Sweden.

AbstractTitle: Coach, vän eller både och? ? en kvalitativ studie om coachning inom arbetslivetAuthors: Jonas Näslund & David ÖhrlingTutors: Ulla Moberg & Larsåke LarssonPurposeThe purpose of this thesis is to examine how coaching in working life serves, aiming to find what influences the interaction between coach and client. To seek to answer the purpose we raised a number of research questions which discussed, among other the coach's intentions and the parties' relationship.TheoriesThis thesis is based on a number of different theories, where the Leader-member Exchange Theory is considered the main theory. LMX is used when studying the relationship between a manager and an employee. Other theories used in this thesis are for example the Social exchange theory and one-on-one-coaching.MethodThe methods used in this thesis are semi-structured interviews, observations and recordings of coaching sessions.

In today?s World is climate change an important and hot topic. Climate scenarios for Sweden show a warmer climate, especially during the autumn, winter and spring. The same climate scenarios also show that the precipitation will increase during this part of the year, however, during the summer the opposite is expected to occur. The purpose of this essay is to examine how future climate change will affect Stockholm especially the expected increase in precipitation, which may lead to a rising level of the Lake Mälaren. During 2000/2001 was Stockholm hit by a flood. This flood nearly resulted in major consequences and showed that there were significant risks for the city of Stockholm and increasing precipitation will result in even more water in the drainage systems of Lake Mälaren. The results presented here show that it is important to increase the drainage capacity of Lake Mälaren in order to reduce the risks of flooding in the central parts of Stockholm.

This essay investigates employee buyouts and does so from a number of different perspectives. Employee buyout is a term that describes a way of ending an employment through an agreement where the employee gets a sum of money in exchange of leaving their employment. Technically it is neither a resignation, since the employee gives up the employment in exchange of money, nor a dismissal since the employer does not have legal grounds for dismissing the employee. Employee buyout is not an illegal way to end an employment, as long as it is the result of a mutual agreement between the employer and the employee. In this essay I investigate and analyze employee buyouts in relation to 7 § in the Swedish employment protection act, and also Swedish employment protection in relation to regulations from EU regarding employment protection.

This study was conducted to investigate the relationship between perceived popularity, social information processing and working memory. With the intentions of examining popularity 209 (98 female, 111 male) children in second and fourth grade were presented with a roster of their classmates and were to nominate whom they liked and whom they disliked. To study working memory capacity a working memory test, that places demands on the participant to work both with and store the given information, was used. To examine children's cognitive processing of empathy-provoking information a cognitive appraisal interview was conducted. The results imply (a) that working memory increases with age, (b) that there is a weak relation between working memory capacity and popularity, and between popularity and cognitive processing styles and (c) that there are some strong correlations between working memory and cognitive processing styles..

This paper examines the opportunities of landscape architect students to integrate with other students which are related to the landscape architects vocational field during their education. It also involves a discussion about the profession of landscape architects and the view of landscape architect students concerning who they will work with in their professional career. Six qualitative interviews were carried out to identify how one work with student exchanges, both within the landscape architecture education program and in voluntary forums during the students' leisure time. The interviewees have experiences of different student exchanges and different approach to landscape architecture education at the Swedish University of Agricultural Sciences (SLU) in Alnarp. During the interviews, it emerged that the number of exchanges for different reasons steadily has declined in recent years. At the same time, the interviewed conceded that exchanges are important to prepare students for their professional career. An electronic survey was sent to all landscape architecture students at SLU Alnarp.

This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow. To test this, the total phenolic content and protein precipitation capacity was estimated in leaf litter from 13 species in both heath and meadow vegetation across an elevational gradient ranging from 500 to 1000 meters above sea level (m.a.s.l.) in the study region. The results showed that elevation and vegetation type both had a strong impact on both variables. Total phenolic concentrations decreased with elevation for the meadow, and were greater for the heath than the meadow.

This report describes the building of a computer model that makes it possible to simulate the thermal climate in a greenhouse. The computer model is built on the physical theory of heat exchange that occur in a greenhouse, such as radiation and convective heat exchange. The model also includes the heat storage that is active in a greenhouse.The computer model is used to simulate the thermal climate in a greenhouse under three periods, winter, spring and summer. It also investigates which effect a concrete wall has on the thermal climate in a greenhouse. The purpose of putting a concrete wall in the greenhouse model is to investigate the possibility to store heat during the day and then use this heat when the temperature drops during the night.The result from the simulations shows that a concrete wall levels the big difference in temperature that normally occurs under a day in a greenhouse.

This thesis aims to investigate the voting premium for companies differentiating voting rights between share classes on the Stockholm Stock Exchange. The voting premium represents the value of a vote attached to the share. The voting premium can be estimated from the price premium between two listed share classes with differentiated voting rights. Rydqvist's dissertation (1987) serves as a model for this study which investigates whether the theory of the so called "oceanic games", along with a proxy variable for cost of control, can predict the voting premium during 2010-2012. To the original model developed by Rydqvist, control variables for differences in liquidity between share classes are added to investigate for an increase in the explanatory power.

Romanization as a method in the bibliographic environment makes retrieval difficult in many aspects. The object of this thesis is to illustrate the importance and the possibility to include non-Roman script in the records of the library catalogue. The questions at issue are about the consequences of romanization, the technical requirements for implementing non-Roman script, and bibliographical resources that have been developed during the last 20 years. The thesis is based on a literature study and correspondence with people who are familiar with the subject. The thesis points out that Romanization causes information to be distorted in various ways and is inconsistent with the requirements of exactitude in bibliographic control.

During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. The truck bundler created bundles that were larger and longer than other bundling equipment on the market. The objectives were to determine the total time consumption and its allocation over work element and machinery, to measure dry matter (DM) content of green and brown LR-bundles.

Introduction: Interplay between all the different subsystems of the financial markets is currently considered as an important internal force in the market. In a financially liberalized economy exchange rate stability is a basis for a wellbeing stock market. If these interactions between all the different subsystems of the financial markets are not detected, this means that there is information inefficiency in the markets.Problem: Can we find any correlation between changes in currency, interest rate and bonds with the stock market index? If so, how do these changes affect the Stockholm Stock Exchange?Purpose: The purpose of this study is to examine if there is any linkage between the interest rate, currency and bonds with the stock market. The researchers wanted to find out how these variables affect the stock market index OMX S30 which consists of the 30 largest companies on the Stockholm Stock Exchange.Method: This research has been based on a quantitative approach.

The purpose of the study is to investigate how board structure influences CEO compensation for companies listed on the Stockholm Stock Exchange in 2004. The theoretical frame of reference is based upon the corporate governance theory, the principal-agent theory and previous empirical research in the area. A cross sectional regression analysis is used, where a number of control variables are included and significance tests are conducted. The study is based on information regarding CEO compensation, and possible factors affecting the compensation, from 267 companies listed on the Stockholm Stock Exchange A- and O-list in the year 2004. We find that the board structure has no significant effect on the CEO compensation.
