SJ is a government-owned passenger train operator in Sweden. SJ currently uses asystem called Ford for control and monitoring of maintenance. Technical andorganizational factors have given Ford the character of a monolithic system withoutflexibility and conditions to meet SJ's increased requirements.The main purpose of this master's thesis is to investigate how data quality can bedefined at SJ and to examine the data quality in Ford. This will give SJ an indication ofwhat their quality efforts should focus on in the future.The technical data quality parameters found are: accuracy, timeliness, completenessand consistency. The user centred data quality parameters are: accessibility,understandability and reliability.

The economic crisis has affected the airline industry as much as it has affected all other industries in the world. The small airlines and maintenance organisations must find new opportunities and options in order to survive the harsh crisis. Priority Aero Maintenance is now an approved maintenance organisation performing maintenance on aircrafts, engines and components. The company sees economic gains in the future by becoming an approved organisation that follows the European Aviation Safety Agency guidelines (EASA) and meets the requirements outlined in the rules of Part-M.In order for the company to become an approved organization, responsible for continuing airworthiness of aircraft, a handbook should be presented to the local authority. This handbook describes the company?s responsibility for the continuing airworthiness in order for the authorities to get an insight into the company and its work.This thesis resulted in a draft of CAME (Continuing Airworthiness Management Exposition) and this draft has been approved by Priority Aero Maintenance.The CAME will in the future be used by the company as a basis for developing a more detailed manual to be presented to and approved by the Swedish Aviation Authority (Transportstyrelsen)..

Entrepreneurship as playing a important role for economic growth has been discussed by a number of theorists such as Joseph Schumpeter and Israel M. Kirzner. William J. Baumol developed these theories as he considered that all entrepreneurship doesn?t lead to economic growth, some entrepreneurial activities may even lead to stagnation.

The essay treats how a process of implementation was executed and the teachers? relation to two curricula, Lpo94 and Lgr11, with two different grading systems, which have functioned as models for one and the same year. The purpose is to investigate the ways in which a change in curricula and syllabus affects teachers in their teaching and assessment practice in the subject of Swedish at secondary school. The investigation had a phenomenological approach and was executed by means of in-depth interviews, questionnaires and one observation. The results are based on a methodological triangulation with qualitative and quantitative data where visible similarities and differences are brought out.

The aim of this thesis was to investigate how the use of the IT-personnelsystem influences human resources and the new challenges and future requirements that may occur, while IT-personnelsystem is used more extensively in the HR-function.Previous research referred to in this study, has focused on how the HR-transformation has contributed to the development of an IT-personnelsystem, which has been used with increasing frequency. This use has created a significant change in the HR-function. This thesis focuses on investigating, describing and analyzing how the practice and development of the IT-personnelsystem meets the needs of the HR-transformation.This study uses qualitative research methods to investigate sixteen users? experiences and our understanding and conclusion is based on both semi-structured interviews and webb surveys. Initially deductive, later on our study took a more abductive approach.The result indicated a variety of uses for a specific IT-personnelsystem dependent on the users? function and positions and also how HR-activity was organized within the business.

70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the requirements for good ecological status. This is mostly due to eutrophication caused by a too high deliverance of nutrients from agricultural land or effluents. Losses of particulate phosphorus through water erosion contribute to a great extent to this eutrophication. In the action plan for the water district cover crops are mentioned as a measure for reducing losses of phosphorus from arable land. This paper reviews the possible effect of cover crops in the water district and discusses what crop that would be most suitable.

SAPA´s resource of waste heat is the basis for this thesis to investigate the possibility of energy assets in their cooling water and possible uses for it. The energy in the waste water is greater than the current need which has three uses which are (1) heating the factory, (2) converting liquid propane to propane gas and (3) local domestic heating. The average energy load that is available is 1, 7 MW and the average temperature in the cooling water is 41°C. The total energy load at dimensioning out side temperature is approximately 1,6 MW for the three current uses. The temperature is currently too low to be used directly in the existing systems so an upgrade is needed.

I takt med den snabba utvecklingen av tjänster på Internet har flera av de ärenden som förr utfördes ansikte mot ansikte hamnat i den virtualiserade världen på Internet. Bankerna har tagit del av denna utveckling och fått de flesta kunder att utföra sina ärenden via deras Internettjänster. Denna möjlighet att utföra sina bankärenden på Internet har inte enbart varit positiv. Phishing är ett problem som dykt upp i samband med den här utvecklingen. Syftet med denna uppsats är att undersöka utifall det finns en medvetenhet hos bankanvändaren gällande Internetbankens säkerhet samt hur användarna hanterar den säkerhetsinformation som banken ger ut.

In the West, travels are often regarded as a given. When tourism is studied it sometimes sounds as if all people have the opportunity to go on vacation when they want and wherever they want. That is not the reality for all. There are laws and regulations on visa requirement which makes it harder for nationals of certain countries to travel on holiday abroad. This essay examines the situation for residents of countries outside the EU and the Schengen Agreement.

AbstractTrendanalys av rapporterade störningar vid de svenskakärnkraftverkenAnalysis of trends in reported safety-related events atSwedish nuclear power plantsSafdar KargarThis degree project was conducted at the Swedish Radiation Safety Authority (SSM)as part of the bachelors program in Nuclear Engineering at Uppsala University duringthe spring of 2011.The Swedish Radiation Safety Authority (SSM) has developed a Windows baseddatabase called ?ASKEN? during later years. In this database more than 12 000 eventreports are stored sorted in three categories, category 1, 2 and 3. The databasecontains events from the start of Oskarshamn 1 in 1972 till present time.All nuclear power plants in Sweden are obliged to report any deficiency in theirbarriers and/or the defense in depth in obedience to SSMFS 2008:1.When a failure is detected or there is reasonable suspicion of a deficiency, the eventreport should be classified as a deficiency of category -1, 2 or 3 [1].The event reports are logged and archived in the register of SSM. The SSM task forceAnalys av Störningar på elproducerande Kärnkraftverk (the ASK-group), evaluates allincoming event reports and categorizes them according to established criteria.The aim of the project is to study and analyze the event reports in the database andidentity interesting observations and trends which should be investigated morethoroughly by deeper analysis to establish any positive or negative trends of reportedevents. .

A technical specification forthe desired end product was developed. With the technical specification as support,design specifications for hardware and firmware were developed.After the specifications were done, a circuit diagram was developed and a circuitboard was made.

Sölvesborg är en stad under expansion, dit lockas folk av en lantlig idyll nära havet. Sölvesborgs kommun har som mål att öka invånarantalet från 16 000 till 20 000 fram till år 2020. Kommunen äger fastigheten Hydro vilken är centralt belägen i Sölvesborg i anslutning till tågstationen. Idag används fastigheten Hydro till en parkeringsyta och kommunen vill att fastigheten ska planeras om för att bli en ny central knytpunkt i Sölvesborg som binder ihop tågstationen och förlänger centrumstråket. Detta examensarbete leder till färdiga förslagshandlingar för fastigheten.

This essay is about the origin, planning and establishment of the European Space Research Organisation's (ESRO) sounding rocket base Esrange outside Kiruna in Northern Sweden. Three main questions are examined. First I show there were not just scientific and technical but also political, economical as well as military reasons to build a European rocket base. Second, I scrutinize the reasons to choose Northern Sweden as the location for the rocket base. As it turns out, the main reasons were the favourable location of Northern Sweden within the aurora oval zone, the proximity of the Kiruna Geophysical Observatory, and the possibility to use a large, although not quite uninhabited, area where the launched rockets could crash.

Idag väljer många företag och kommuner att placera data i molnet istället för på en lokal server, detta medför nya problem som tidigare inte varit aktuella. Datainspektionen har påpekat brister i hur två kommuner använder molntjänster för att lagra personlig data då de ställer sig tveksamma till molnleverantörernas hantering av data samt insynen till molnleverantörerena. I detta arbete kommer det undersökas hur den svenska personuppgiftslagen fungerar när data läggs ut i en molntjänst. Resultatet av uppsatsen kommer även visa på de olika säkerhetshoten som finns i molnet och se vad säkerhetsexperter säger för att ta reda på om kommuner och företag är medvetna om och uppmärksammar samma hot. För att ta reda på detta har intervjuer genomförts med en svensk molnleverantör, företag som utvecklar tjänster mot molnet, privatpersoner som nyttjar molnet och experter inom säkerhet från Blekinge Tekniska Högskola, BTH. Resultatet av studien visar att det är svårt att se om en amerikansk leverantör uppfyller de svenska lagarna för personuppgifter, det visar också att det är teoretiskt möjligt att anlita en svensk leverantör och uppfylla lagen. Det har även visat sig att den största oron gällande molnet är bristen på kontroll av data..
