Development in spin dynamic occurs in the whole world because of therising demands on fast electronic storage for example hard drivesand RAM (Random Access Memory). Measuring the spin resonance of amaterial gives you the insight of the theoretical speed for amagnetic memory. This means the maximum storage speed is below thefirst resonance. All magnetic materials have different propertiesthat will inflict the resonance frequency which brings that theconstructors of memories need to know which magnetic material theywill use to obtain best results. In the market for normal users themaximum storage speed in a RAM memory is 1.6 GHz.

This report presents a master thesis project performed at Elekta AB during the fall of 2013 and early 2014. Elekta is a medical technology company and their main product in the Stockholm office is a gamma knife used for radiosurgery. The gamma knife contains a cluster of a dozen motor servos and motors used for adjusting the patient and the radiation sources over a CAN bus. A self-developed hardware-in-loop simulator running on a PC with LabVIEW is currently being used for integration level testing of the control system of the gamma knife. The simulator has some problems with it not running in real-time and having other performance issues.

Financial bubbles are characterized by a large increase in the economic growth on the market as a whole or in specific industries. The change gives rise to an increase in the capital needed to finance this growth. Companies typically have a choice between equity and debt capital to finance its business and the mix of these types of capital is often referred to as the company?s capital structure. There has been a lot of research done in the field of financial bubbles and ofcapital structure, as of yet no studies seem to address these two areas in combination.The aim of this study is to examine if financial bubbles affect a company?s capital structure and through this also examine if the supposed changes in capital structure can be generalized.The study comprise of two identical time-series which examines the changes in leverage and the choice of financing during the Swedish real estate bubble in the early nineties and the IT-crash at the end of the 2000th century.

In this essay, I have examined and discussed the similarities and differences between christology in the thought of Cyril of Alexandria and Martin Luther, and further, to what extent Luther may have been influenced by Cyril in his doctrines of christology and Christ?s presence in the Eucharist. By reading texts written by Cyril as well as by Luther, I have tried to describe the position of each of the theologian?s. In the next step, I compared the thoughts of Cyril and Luther, and tried to show on both similarities and differences.

This essay deals with the same task that utilitarians have tried to solve for a long time, what is happiness? In the eighteenth-century utilitarians suggested that happiness should be the base for social political decisions. But the lack of definition disposed so that GDP became the measurement of happiness, which proved to be wrong when the unhappiness continued to increase. More than two hundred years later scientists came up with a new definition of happiness and new ways to measure it. And during the last decade economists have taken the discussion to a higher level.So once again we?re dealing with the same old issue, if happiness ought to be the base of social political decisions.

På uppdrag av SWECO Management AB utreds möjligheten till att kunna se korrelationer mellan åtgärder på en fastighet eller i dess omgivning och ett förändrat fastighetsvärde. Denna information skall vara SWECO till gagn i upphandlingssituationer, för att lättare kunna visa för beställaren om att tjänsten i fråga kan leda till ett ökat fastighetsvärde. Med utgångspunkt i den begränsade litteraturen, har information främst samlats genom en intervjuprocess med representanter från fastighetsbranschen. För att få ett brett perspektiv i ämnet, har representanter med olika befattningar, olika lång erfarenhet och med varierande utbildningar intervjuats. I studien görs avgränsningar om makrofaktorer, såsom konjunktursvängningar, ränteförändringar, finanskriser, låneinstitutens förändrade låneregler etc.

This thesis describes the planning and development of a volume meter of pine and spruce cones. The product was designed and developed for Stigsjö Skog och Frö AB in Härnösand. It was developed taking into account a number of requirements set by the supervisor David Zetterlund. The main requirements were that the volume measurement would be fast and give accurate results. These are two requirements that are missing in today's volume measuring method which is very problematic for the company.The plant was visited several times in Härnösand, mainly to discuss the generated concepts with the supervisor and perform tests on the prototype.

Around year 2004, a new service was introduced on the Swedish housing market with the purpose of increasing the sell price, namely homestaging. Homestaging means that a home gets in order before a open house, for example by removing personal affections or the leasing of new furniture. The phenomenon originates from the United States, where it has existed for several decades.Most components, but not all, that is included in the homestaging concept is tax-deductible and this has lead to several questions around the law and foremost within tax law. To elucidate this complexity of problems around the right to deduction for homestaging, the Swedish tax agency, Skatteverket, has formulated a letter stating the authority?s attitude towards the phenomenon.

To be able to evaluate different radio waveforms in a laboratory environment FOI in Linköping has developed an experimental system for radio communication called Rasmus. The system consists of a transmitter, a channel emulator and a receiver. The transmitter modulates a digital signal to a desired analogue waveform. The channel emulator is used to simulate a real radio channel. The channel emulator distorts the signal by splitting it up in several propagation paths.

This report is intended to give an insight in the Network Performance Assessment Modeland the parameters that is needed in the making of a fictitious grid that represents anoptimal grid. A main goal is to investigate how the construction of a real grid iscompared to the fictitious.One of the key parameters is how redundancy is treated in the model and to find theoptimal amount of redundancy versus the costs. Further is the dimensioning of the grid ofinterest. The fictitious grid is based on energy whereas the real grid often is based onsubscribed power and these two principles are compared and analyzed.The difference in the outcome of the model result due to variations in input data of themodel is also discussed in the report..

The moisture content in 10 deliveries of tree parts and 10 deliveries of wood residues were measured with different methods to analyze the quality of procedure used at Dåvamyran today. At the same time a survey was made on the measure procedures used at heating plants in Sweden The majority of the heating plants in Sweden use weight and moisture content as base for payment but at some plants only volume. The moisture content is usually estimated by drying wood chips in an oven but few plants a visual estimation is used. At few plants moisture content is estimated spectroscopicily. The techniques using near infra read light and other electromagnetic are still at a test stage. The methods of measurement used today are quit unreliable for the individual deliveries and there is a risk for systematic mistakes.

There are various value-influencing factors that have various effects on the value of a cooperative flat for buyers. What generates value is individual and different from buyer to buyer, but also between buyers and real-estate agents. Consequently, the real-estate agents who perform valuations can make incorrect estimates of a residential value. Therefore, it is important to examine which factors are important for buyers to prevent incorrect valuations. To find out which these factors are and which of them that are the most important for potential buyers, previous research has been done in larger cities in both Sweden and other countries.

Fält Elektronik AB i Kalix utvecklar och tillverkar bland annat larmsändare för fast uppkopplade larmnät. Fast uppkopplade larmnät används för att åstadkomma övervakad och säker överföring av larm och annan information mellan tekniska system för skydd och säkerhet. Larmöverföringen är ständigt övervakad från larmanläggningen ända fram till larmcentralen. Ett problem som idag finns i larmnät är att om man tappar kontakten med en larmsändare så vet man bara att man tappat kontakten, men inte varför. Därför vill man nu utveckla ett instrument som kan mäta och kontrollera vad som orsakar att uppkopplingen bryts t.ex.

This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.

Use of computers and computer networks is nowadays a part of everyday life. You do not use them only at home when you sit at you computer, but you can use them all the time everywhere. This can involve everything from surf to any website when you are at home, to checking your email on your mobile when you are on your way to work. Most people do not think about how it really works when they try to access a web page by typing the address into their browser, but something that most people probably notice is how long it can sometimes take to access a web page.All items which are directly connected to the IP network have a unique IP address that is used to make it possible to communicate. The IP address is either a period separated sequence of digits representing 32 bits or a colon separated sequence of digits representing 128 bits, depending on whether the address is an IPv4 or IPv6 address.
