Många berättar om de ekonomiska vinster de gjort på börsen under senaste åren, och hur lätt pengarna rullat in på deras konton. Med en liten inblick i finansmarknaden och genom att titta på A-ekonomi då och då så blir i stort sett alla aktieaffärer lyckade. Vi hör dock sällan någon berätta om folks dåliga aktieaffärer. Börsen verkar med andra ord vara en guldgruva för dem som investerar där. Med hjälp av dyra aktierekommendationer kan man göra ännu större vinster enligt en rad olika fondkommissionär.

Ett av de mest notoriska dilemman i dagens kosmologi är den mörka materians natur och dess förekomst i universum. Mot bakgrund av detta har nya forskningsdiscipliner med rötterna i Einsteins relativitetsteori växt fram, bl.a. teorin om gravitationslinser som möjliggör en indirekt observationsmetod av ljussvaga kompakta objekt som annars skulle vara mycket svåra eller omöjliga att upptäcka på traditionella vis, såsom svarta hål.Via en genomgång av grundteorin för gravitationslinser, några enkla teoretiska studier och en grundläggande felmarginalsanalys illustreras hur olika typer av kompakta objekt i Vintergatans omedelbara omgivning kan ge upphov till vissa karakteristiska linsfenomen. Detta sätts i relation till rådande teorier om den tidigaste stjärnbildningen och de massiva kompakta rester som denna generation av mycket massiva stjärnor bör ha efterlämnat ? i synnerhet intermediära svarta hål med massor på 100-1000 Msol som ännu kan finnas i dagens mörka galaxhalor.

Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

This report is a documentation of the workflow and the result of a project carried out by twostudents from the Royal Institute of Technology in collaboration with a company. The report isstructured in a chronological order and describes the methods and systems developed in theworkflow. The report shows how the project evolved from a study phase to the various proposals onthe concept solutions.The project aims to develop a systematic way of bonding two different kind of cardboard under fiveminutes. By conducting a general study about glue and its different forms it was possible to obtain abroad knowledge, which helped to choose the right substances to later use in testing on the differentcardboard materials in question. Glues's survey resulted in a list of different substances that wererelevant to the project.

The aim of this report is to analyse the use of the capacity at the CNC (computer numerical control) cutters and show how the level of set up time for these cutters at Stålöv AB. This assignment is concrete whereas there are no subjective questions to this matter and there are only cold figures presented.Production economy is getting more important as the competition hardens and there are several different ways to increase productivity and efficiency in a company. In order to increase productivity and efficiency work studies are used to, through an analysis, find developments in methods that result in improved work methods and to establish the time that are used. Increased production of different parts and customer driven production in combination with increased demands on rationalisation of capital have led to an enlarged interest for shorter set up times in the production.To point out the use of capacity and the set up time of the cutters at Stålöv AB we used frequency studies. Frequency studies are work measure methods based on random observations on predetermined events to calculate the relative occurrence of these events.

With the new generation of smartphones the boundaries for what is a mobile phone and whatis a computer becomes more subtle. 2009 the shipment of smartphones with touchscreen morethan double the 2008 figure and the total amount of smartphones is now over 10 % of the totalworldwide shipments of mobile phones. There?s still one problem to solve and that is the lackof web content specifically adapted for smartphones.The purpose of this paper is to identify and analyze from a user and usability perspective howto make a successful migration and design of a user interface for an existing web basedsystem so that it also fit smartphones.The paper starts with a theoretical reference material containing examples of differentapproaches for design and migration of an interface.A case study is performed and prototypes are designed with support from guidelines andrecommendations in the theory part.The conclusion stipulates that in the present situation there are no shortcuts when it comes tomigration of an existing web based system for the mobile web. The recommendation is aspecific interface for each different unit that are going to interact with the system.Research that analyzes differences between all mobile web browsers would be of greatinterest, a research that hopefully leads to guidelines for what level of mobile web standardthey should at least support.

Det kom allt fler signaler att ensamheten bland äldre har ökat, även att äldres känslor av ensamhet har blivit ett problem som påverkar den ensamme psykiskt negativt. Sveriges äldre generation över 65 år beräknas att öka med ca 22 procent mellan åren, 2005-2010. Ett ökat behov av socialt umgänge bland de äldre i kommunen blev anledningen till att Röda Korset engagerade sig i uppsökande verksamhet. Detta sker med hjälp av frivilliga medmänniskor som besöker äldre som lever i ensamhet. Syftet med studien var att utvärdera hur Röda Korsets uppsökande verksamhet har fungerat för de berörda äldre i Karlskrona kommun.

I denna rapport utreds olika metoder för att kunna reglera vattennivån i vattenkraftverket Avesta Lillfors i Dalarna. Två kraftverk ligger endast 900 m uppströms och detta gör att svarstiderna blir korta och regleringen blir lätt nervös. Att använda sig av vattennivåreglering i ett kraftverk för-enklar dess styrning då anpassning till inflödet sker automatiskt.En flödestabell har tagits fram genom mätningar i turbinen, med hjälp av Winter-Kennedy-metoden. Denna tabell används för att kunna fram-koppla regulatorn och därmed dämpa stora variationer i inflödet. Dessu-tom har en modell av älven skapats och testats med en återkopplad PID-regulator.

The aim of this thesis was to investigate the possibility of integrating an item tracking systemwith a monitoring system currently under development at Fifth Generation Technologies (P) Ltd.A literature study of RFID technology and the networks ZigBee and MiWi was done. Based onthe literature study a concept for a distributed system was developed.The concept is to have several RFID readers placed in the area where tracking is to be performedand allow them to communicate with each other through wireless communication. The RFIDreaders shall be able to form zones and filter the data that is forwarded from the zones to theservers and thus perform some of the work that the server would normally have to do. Theconcept has been evaluated by prototype development and testing. The prototype uses an ultrahigh frequency RFID reader and a MiWi network.The test indicated some limitations with the selected technologies.

Sambandsanalys av surveydata kompliceras av förekomsten av slumpfel och metodeffekter i de avgivna svaren. Dessa felkällor kan leda till betydande över- eller underskattning av sambanden mellan undersökta variabler, och riskerar att leda till felaktiga slutsatser.En sedan länge känd metod för att estimera och kontrollera för slumpfel och metodeffekter i enkätdata är den så kallade Multitrait Multimethod-metoden (MTMM). Nackdelen med MTMM-metoden är att den kräver att varje fråga som ska analyseras ställs minst tre gånger i samma enkät, vilket gör att ansatsen i praktiken oftast inte är möjlig att tillämpa. Sedan 2012 finns dock ett verktyg, SQP 2.0, som gör det möjligt att skatta slumpfel och metodeffekter i enkätdata utan att genomföra MTMM-experiment. Den här uppsatsen utvärderar prediktionerna från SQP 2.0 på en enkät om arbetslivsrelaterade frågor besvarad av svenska och brittiska respondenter.

Generally, the economic health of Swedish roundwood truck transport companies has not been good. Profitability is important for maintaining the stability in the transport business, which is a condition for long-term transport planning in the forestry sector. The scope of this study was to identify probable factors influencing the profitability of roundwood truck transport companies and quantify the influence of these factors on economic results. The study was carried out at a major roundwood truck transport organisation in mid-Sweden and was implemented in four steps. In the first step economic results from the haulage contractors were collected and a random sample was taken from accounted net margin for the account year 2005/2006. In the second step hauliers were interviewed to identify probable success factors. At the third step data for identified factors were gathered through a questionnaire.
