Quality of Service i IP-nätverk
The original promise behind the Internet Protocol was to deliver data from a sender to the receiver using a best-effort approach. This means that the protocol makes no guarantees except that it will try to deliver the data to the destination. If some problem occurs the packet may be discarded by the network without any notice. No guarantees are made regarding the time it takes to deliver the data, the rate at which data will be delivered or if data is delivered in the same order it was sent. The best-effort approach is arguably the reason behind the success of the Internet Protocol and is what makes IP scalable to networks the size of the Internet.
Paketering av digital musik: Intervjuer med nyckelpersoner inom digital musik i Sverige

Riskhantering i projekt : Modell för uppföljning
In April 2010 Vägverket (the Swedish National Road Agency) andBanverket (the Swedish National Railway Agency) will merge intoTrafikverket (the Swedish National Traffic Agency). Trafikverket willassume unified responsibility for the risk management that atpresent is responsibility of Vägverket and Banverket separately. Atpresent, as it will be shown in this thesis, Vägverket and Banverketshare the same theoretical background for risk management but usedifferent implementations often within the same agency. The use ofdifferent implementations results in a reduced transparency of therisk management both within and outside the agencies: this willbecome even more problematic when they will be fused intoTrafikverket.The aim of this thesis is to review the current risk managementmethodologies used at Vägverket and Banverket and to suggest aunified tool for the risk management at Trafikverket. This will bedone by focusing in particular on construction projects, one fromVägverket (Partihallsförbindelsen) and one from Banverket(Nynäsbanan).
Gäddfisketuristerna : En kartering och marknadssegmentering av de Europeiska marknaderna för gäddfiskande turister i Sverige
This investigation indicates that there are regions within Europe that seems to have similar preferences and priorities regarding pike angling travels to Sweden. Swedish pike angling facilities process in first hand markets with favourable economic circumstances and a cultural interest for pike angling. There was a big differences in features between the Northern, Western, Eastern and Southern regions of Europe. They also seems to be tied to specific regions within some of the nations.The regions have diverse requirements and distinguish in terms of consumption and preferences regarding different aspects of pike angling. From there it is possible to divide pike angling tourists into segments.
Klimatkalkylering
Detta är en studie om klimatpåverkan i samband med anläggandet av järnvägsbroar i syfte att ta fram nyckeltal (moment, material, mängder) för att effektivt kunna reducera utsläppen av växthusgaser. Till grund för studien har vi arbetat med Trafikverkets verktyg klimatkalkyl 2.0. Det har granskats utifrån användarvänlighet och riktighet i indata och emissionsomräkningsfaktorer. Det för att se till skillnaden mellan modellen och ett unikt anläggningsprojekt, var skiljer sig Trafikverkets typvärden mot de projektspecifika förutsättningarna samt vilka blir dess konsekvenser?Studien har kommit fram till att utan viss försiktighet vid arbete i klimatkalkyl 2.0 finns risk för inkorrekta resultat.
Faktorer som inverkar på prisbildningen inom factoring
Banks have been some of the biggest operators on the market of business customers financing. When the Swedish Förmånsrättslagen was changed 2004 the banks became more restrictive to allow traditional bank loans. The change made it more difficult for customers to get their loans granted. For that reason customers had to find other forms of financing. Factoring is an alternative that means companies can mortage/sell their claim on customers to finance companies.
Inflytande i teori och praktik : En kvalitativ maktanalys över arbetet med individuella planer enligt LSS
People with certain types of disabilities have the legal right to ask for an individual plan. The idea is that the plan should be a tool for the disabled to get more power and influence over the planned actions that involves their lives. The aim of this thesis was to study the individual circumstances of interpersonal power and influence in the work of individual plans. The study was done with a qualitative approach, where three executing officers and three individuals were interviewed. The results show that the conditions for the individual?s influence are far more complicated than at first glance.

C2-monitor : en rapport om utvecklingen av ett mobilt gränssnitt
This report presents the development process of a mobile interface for the C2-monitor. A monitoring tool used to support the operations for the broadcasting services of Ericsson Broadcasting and Media Services (EBMS). With the support of the C2-monitor, operators can monitor hundreds of channels and services produced from EBMS. To enhance a more flexible working environment, the C2-monitor needs to be developed further to support mobile devices with a customized design to take advantage of mobile phones features and functionality. Established and well-recognized design methods and principles have been applied in the development process and user testing have been made iteratively throughout the project.
Nätverkens betydelse för turistdestinationen : en studie av gotländska turistrelaterade nätverk
The tourism industry is growing and with its growth competition between destinations rises. In competition, cooperation and collaboration between tourism operators seem beneficial when creating an attractive and dynamic tourist destination.The purpose of this study is to describe and discuss the significance and influence of tourist related networks at a tourist destination, and therefore this study aims to examine the question: What significance do the tourist related networks have at a tourist destination?This study focuses on seven networks on Gotland that are tourism related, and the representatives of the networks were interviewed in order to get their view on the network and its significance to the destination. The study shows that networks have an important role in creating a unified tourist product of the destination, and in reaching out to the potential visitors through joint destination marketing. The study also shows that the tourism related networks helps to improve the reception of the tourist at a destination and to secure the quality of the tourist destination and its tourist products..
Identifikation av produktionsstörningar och obalanser vid tillverkning av golvskenor
Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..
Utmattning av järnvägsbroar i armerad betong : Enligt eurokoder
Commissioned for this report is Ramboll, Bridge and Tunnel Unit in Stockholm. Theidea throughout the work has been to primarily help bridge designers compilingadvice and instructions on how fatigue verification for railway bridges in reinforcedconcrete shall be performed under the new rules, the Eurocodes.After the introduction of the Eurocodes in 2011 has major problems emerged amongdesigners around Sweden. In some areas, it differs in the calculation rules comparedwith rules from the Swedish Transport Administration and the National Board ofHousing, Building and Planning calculation. Fatigue verification is one area where thenew calculation rules are different from the past.A large part of the report has been to interpret and find the relevant information inthe Eurocodes concerning fatigue. When questions or doubts have surfaced, this hasbeen discussed with Elisabeth Helsing at the Swedish Transport Administration andbridge designers at Ramboll.The result is a report where the structure is organized in the way that the bridgedesigners can move from cover to cover and realize that fatigue verification in realityfollows the same order as the report's sections.
