Eskalerande projekt i offentlig sektor - En fallstudie av polisens utredningsstöd

A large number of system development projects are allowed to proceed for too long, and leads to undesirable project outcomes. Research shows that more than half of the authorities involved reported that at least one of their projects have exceeded their budget, and that a third of all the projects had exceeded the budget. This problem led to the following research question: ?Which factors can explain projects continued escalation within public authorities?? To answer the question, a qualitative case study of the Swedish police?s implementation of PUST, a sort of case management system was conducted. The project received considerable media attention and a large amount of criticism was directed towards the project, partly because the project exceeded the timeframe and budget set at the start.

Enklare korglutning

This project was led on behalf of Bombardier Transportation in Västerås, Sweden, incollaboration with KTH Stockholm and EPFL Lausanne. This project is connected to thedevelopment of a new and simplified tilt system for rail vehicles.Growing competition from other means of transportation has forced railway companiesthroughout the world to search for increased performances.Travelling time is the mostobvious performance indicator that may be improved by introducing high-speed trains.They require very large curve radii and long transitions curves not to impairridecomfort, another performance indicator. Building new tracks adapted to high speedtrains is very costly and can only be justified where the passenger base is large.Trains with the capability to tilt the carbodies inwards the curve is a more cost efficientalternative. The tilt inwards reduces thelateral force felt by the passengers allowing thetrain to pass curves at enhanced speed with maintained ride comfort but increases thefrequency ofmotion sickness.The benefits of tilting trains are improved speed capability in curves and enhancedpassengers comfort, but at higher buying and maintenance cost. As the conventionaltrains increase their speed in curves, the performance advantage of tilting trains isreduced while their prize is still kept significantly higher and constant.

Framtidens D250S Dual batteriladdare

This thesis aims to develop proposals and models for a modular electronics construction to a future D250S Dual battery charger. The aim also includes investigation of possibilities to use some of Texas Instruments C2000 microprocessors. The reason for this is that CTEK SWEDEN AB wants to renew the present D250S Dual battery charger and lower the manufacturing costs. The thesis work has involved gathering theoretical facts for the development of a design on the modular electronic construction, the choice on which microprocessor to use, the choice of electronic components and facts about peripheral equipment to the D250S Dual. With the theoretical there has been developed different solutions to the proposed hardware and software solutions with comparisons in aspects of positive and negative.

Through the growing use and availability of information technology the dependency of Internet is today increasing. Internet makes ways for a more mobile business communication that cost less. One of the latest applications of Internet technology are intranet and extranet. I have asked myself the question how intranet and extranet can affect companies efficiency and competitive advantage. In order to answer this question I performed a case study at Ericsson and ABB.

Jämförelse mellan våtkompostering och andra VA-system i omvandlingsområden : en fallstudie i Norrtälje kommun.

Eutrophication of the Baltic Sea and Swedish lakes remains a major problem despite many years of effort to reduce the emissions of nutrients. One major source is waste water systems, especially private sewage systems. These sewages accounts for a very large share of nutrients per capita in comparison with citizens connected to larger sewage treatment plants. Norrtälje community has the greatest number of private sewage systems in Sweden. Discharges of nutrients, especially phosphorus, to the Baltic Sea from these sewage systems are significant.

Hur har införandet av automatiska mjölkningssystem påverkat juverhälsan hos mjölkkor och vilka riskfaktorer finns?

Today, there are more than 12 000-14 000 farms worldwide using an automatic milking system (AMS). Studies have shown that transition to AMS affects the udder health of cows adversely, recognized primarily as elevated somatic cell counts. There are several reasons for this, for example the greater variation in milking frequency seen in AMS. On one hand, short milking intervals may lead to bad teat condition of the cows due to the stress the milking procedure exposes the teats to. Too long milking intervals, on the other hand, seem to predispose for milk leakage, which is, in turn, a risk factor for the development of mastitis.

Klassificering av processutrustning - en grund för riskbaserat underhåll

In this report a systematic working procedure for risk classification of processing equipment from a maintenance point of view is described. How this system has been worked out is also an important part of the report. The classification system is adapted for use in complex processing plants. Preemraff Göteborg has been subject for the underlying study and application of the system.The system aims to give a good overview of the maintenance related risks at the plant. Furthermore, the analysis result is a good motivation for the suggested maintenance activities and as motivation for extended or decreased maintenance resources in total.

Att leva med barn som har ADHD. : Familjemedlmmars upplevelser av att leva med barn som har diagnosen ADHD.

Syfte: Studiens syfte var att undersöka samband mellan hur universitetsstudenter skattar sin fysiska aktivitetsnivå och hur de registrerar aktivitetsnivå med hjälp av dagbok samt att se om de kom upp i ACSM (American College of Sport Medicine) och WHO´s (World Health Organisation) rekommendationer.Metod: Studien hade en icke experimentell, deskriptiv och korrelerande design där 26 försökspersoner, två män och 24 kvinnor, rekryterades via anslag. De fick först svara på en enkät och därefter registrera sin aktivitet via en 7-dagars aktivitetsdagbok.Resultat: Studenterna ansåg inte att de hade en stillasittande livsstil och alla deltagare utom en ansåg sig komma upp till ACSM´s rekommendationer av fysisk aktivitet 30 minuter per dag av måttlig intensitet alla dagar i veckan. Trettiofem procent kom inte upp i WHO´s rekommendationer och av dessa överskattade 67% sin fysiska aktivitetsnivå. Sextiofem procent kom inte upp i ACSM´s rekommendationer och av dessa överskattade 94% sin aktivitetsnivå.Konklusion: Studenterna hade en låg fysisk aktivitetsnivå utifrån ACSM´s rekommendationer och majoriteten av de som inte levde upp till WHO och ACSM rekommendationer överskattade sin fysiska aktivitetsnivå. Det krävs dock mer omfattande studier för att dra några generella slutsatser då denna studie hade en skev könsfördelning och ett lågt antal deltagare.Keywords: Self-estimation, Perception, Activity diary, Physical Activity level, Overestimation. .

Effekter av nya PBL : En studie av processen från handläggning av bygglovsansökan till slutbesked

It has now passed two years since the new site- and construction law, PBL, went into force. It replaced the previous PBL applicable since 1987, and it involves relatively large changes in many different areas of the construction sector. The ambitions of the new law are for instance to simplify and clarify the legal text, increase efficiency in the permitting processes and improve the quality of construction. To achieve this, a variety of changes was made. Some of the most important are: inserted deadline in the processing of building applications, extended assessment of building applications, revised rules about controlplan and quality manager, a certificate is required to start and end the project, an additional meeting is inserted and the construction management of the municipalities will have to do a mandatory visit at the work scene.

Purpose: The purpose of this study is to enlighten and find understanding about stock return versus dividend on the ex ? day and try to figure out if abnormal returns occur on the portfolio during dividends.Methodology:The study was based in a quantitative nature and was derived with an event study and a hypothesis testing. The authors investigated the thirty most traded shares on the Stockholm stock exchange during a period of five years (2005 ? 2009). They were analyzed during a total of nine days; the estimation window was set to sixty days.

Identifiering av konfliktbestånd med hjälp av laserskanning

The interest in harvesting wood fuel in conflict stands has grown in recent years as a consequence of the increased demand for biofuel. Conflict stands are young forests that have not been cleaned and have a large number of stems ha-1with a great height and diameter distribution. This means that traditional field measurements in conflict stands are difficult and very time consuming. Therefore, the forestry sector is in need of new, more efficient inventory methods. In this study, the Lidar data from Lantmäteriet?s (the Swedish mapping, cadastral and land registration authorities) new national height model was used in combination with plots from the Swedish national forest inventory from 2009 to create functions for; height, volume, diameter and number of stems.

Isolerande och skyddande dubbelväv - Produktutveckling av ett kylande fodral

Denna rapport beskriver en produktutvecklingsprocess som behandlar utvecklandet av ett textilt material som isolerar och skyddar. Det textila materialet ska fungera till ett kylande fodral utan att förstöra dess funktion och behöver därför uppfylla en speciell kravspecifikation. Materialet ska isolera mot kroppsvärme, vara stabilt, skyddande och slitstarkt. Dubbelväv valdes tidigt i arbetet då det är ett enkelt sätt att kunna påverka det textila materialets egenskaper i form av material- och konstruktionsval, i en betydligt större utsträckning än i en enkelsidig väv. För att utveckla ett material med de efterfrågade egenskaperna har tester utförs och den metod som har använts är hypotesprövning.
