Syfte: Syftet med denna studie var att se hur och varför volatiliteten påverkades i DJIA, S&P 500 och NASDAQ Composite under IT-bubblan.Metod: Års- och månadsvolatiliteten för DJIA, S&P 500 och NASDAQ Composite har beräknats under 1995-2004 med hjälp av data från Yahoo Finance.Empiri: Resultatet visar att volatiliteten var väsentligt högre i NASDAQ Composite än vad den var i S&P 500 och DJIA som i sin tur höll en liknande volatilitet i förhållande till varandra.Analys: I analysen framträdde det att volatiliteten blev väsentligt högre i samband med att bubblan sprack under maj 2000 fram till dess att paniken lade sig kort efter maj 2002. Det fanns en hög överensstämmelse mellan denna rapport och övriga tidigare studier. Teorierna var mestadels väl applicerbara.Slutsats: Volatiliteten för DJIA, S&P 500 och NASDAQ Composite var som högst mellan 2000 och 2002 under undersökningsperioden 1995-2004. IT-bubblan uppstod samt sprack till följd av irrationellt investeringsbeteende bland investerarna på aktiemarknaden och paniken som uppstod efteråt gjorde att volatiliteten på aktiemarknaden höll sig förhållandevis hög fram tills den lade sig kort efter maj 2002. NASDAQ Composite hade högst volatilitet till följd av IT-bubblan medan DJIA och S&P 500 hade likvärdig volatilitet.

Mastitis, an inflammation of the udder mainly caused by a bacterial infection, induces an increase in the somatic cell count (SCC) in milk and is consequently one of several factors affecting SCC in milk. In this literature review it is investigated whether SCC; on udder quarter, cow composite or bulk tank milk level, can be used as a quality marker with focus on milk composition in terms of the content of fat, lactose, total protein, casein and whey protein. According to this literature review the relation between SCC and milk composition is not reliable either on udder quarter, cow composite or bulk tank milk level. SCC was related to lactose, casein and whey protein on udder quarter level; lactose and whey protein on cow composite level and lactose on bulk tank milk level.

The term ?Object Shift? means that a weak object pronoun has been raised to a position to the left of a sentence adverbial. Primarily, there are two positions to which a weak object pronoun can be raised; one of them is called Long Object Shift.In this paper, I primarily deal with finite verb frequencies in sentences with Long Object Shift in Swedish. Also, in order to further define the verbs in these sentences I discuss verb semantic and syntactic valence in relation to the shifted object. Furthermore, I discuss the search methods which have generated sentences with Long Object Shift in written sources in Swedish; an equivalent study has never been done before.

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

This Master Thesis is a product development project that has been carried out in cooperation withSvea Teknik AB. The company has developed an apparatus for attachment of a keel to a hull base ofa boat. The purpose for this thesis has been to compare a new concept of keel attachment incomposite material to thetraditionaldesign solution. This new keel attachment minimizes thedamages that may arise on the keel and the hull of the boat in shape of stresses impacts at grounding.Today it is a problem, relating to keel attachment on sailing boats having a fin keel or a bulbous keel.The manufacture focus on developing larger draught and shorter keel blades. The overall purpose isto increase performance of the sailing boat.The task for this thesis was to develop a concept of keel blade in composite material and investigateattachment to a sheet-shaped element.

Today many different types of lock systems are used all over the world. Passwords, finger prints and magnetic strips are a few examples. When the key is a three dimensional object, lika a physical metal key, the security depends, in a high degree, on that you can?t copy the object without access to it. One approach to copying the object is photographing the object, and from these photographs create a copy.

When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.

This paper investigates whether the traditional accrual based trading strategy first documented by Sloan (1996) can be refined using fundamental analysis. Specifically, this is done by implementing the composite signal F_SCORE introduced by Piotroski (2000) to identify financially strong or weak firms. We find that by applying both investment models simultaneously, in a model we call P_KOMB, the mean market-adjusted return earned by an investor exploiting the accrual anomaly can be increased by 14.8% annually. This is achieved by taking a long position in strong firms (as defined by the composite signal) in the lowest accrual portfolio, while an offsetting short position is taken in weak firms in the highest accrual portfolio, repeated annually between 1997 and 2007. Consistent with prior studies, positive market-adjusted returns can be attained through assessment of accruals as well as key value drivers found in historical financial data.

This thesis is covering my design of an architectural object for the use in a pedagogical setting. The purpose is to create contextual premises for students, making possible the testing of designs, involving plants suitable for the urban environment. Hence, the main features in the object design is suggestive to the urban outdoor rooms - rooms that are formed amongst the city facades. The thesis is also about the design process set out from a technical reality, based on camera imagery. To a large extent, the thesis consists of reflections concerning the object's function towards pedagogy, perception and materials. Furthermore, the object claims to be a hybrid between architecture and landscape architecture.

This master thesis deals with the theme of memory, it is through an artistic process I have investigated and peeled off to a specific memory, the hut. It is in the work of the personal memory through a craft process it transforms into something public. The hut is constructed out of corrugated boxes, corrugated boxes casted in clay. To cast an object differs according to me from sculpting the object; it is the function rather than the sensual feeling that is sought after. It is about the clarity and accuracy through the casted object that suggest something vague and indeterminate.

We are surrounded by things. They have their own personalities. Some evokes our emotions. We want to own them. We develop strong relationships to each other.

I examine how relationships between people and objects are created and continues through contiguity every time one use or touch an object and through participation through use and memories. The aim is to continue a relationship and to keep a communication alive with people beyond time and space, then, now and henceforth. I take advantage of and transform the traces in an object that belonged to someone. Parallel I create new space for bodies to put their mark for the first time. I compare my work with the Nordic Museum's task to preserve the present for the future.

The University of Gotland has between the years 2006-2011 conducted seminar excavations in Västergarn parish, Gotland. During this time 167 comb fragments have been registered. Out of these are 51 of importance for this study, since they are defined as either a single-sided composite comb or a comb case. The purpose of this thesis is to enlighten the earliest period in the history of Västergarn by focusing on the earliest forms of combs and their cases. And as the title expresses do the combs date to the Viking Age or the Middle Ages? The combs from the excavations will be compared to different type schemes, both Viking Age and Middle Age and different places in Scandinavia such as Lund, Oslo, Lödöse and Gotland.
