Optimering av antenndesign utifrån experimentella data

During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak ? to - peak was brought on the signal. The measurements are presented in a line diagram.

Effektiv och underhållssäker lagring av medicinsk data

Creating a database to manage medical data is not the easiest. We create a database to be used for a presentation tool that presents medical data about patients that is stored in the database. We examine which of the three databases, MySQL with relational design, MySQL with EAV design and MongoDB that are best suited for storing medical data. The analysis i performed in two steps. The first step handles the database that is most effective to retriev data. The second step examines how easy it is to change the structure of the various databases. The results show that depending on whether efficiency or maintenance is most important, different databases are the best choise. MySQL with relational design proves to be most effective while MongoDB is the easiest to maintain..

Asymmetri - ett förräderi?

This study aims to disclose how an asymmetric planogram structure of the brand with the highest actual variety may come to affect the brand itself and its category as a whole. The authors of the study feel that there is a gap still unfilled amongst previous extensive research examining how differences in either space or price vary between categories, products or brands. An in-store experiment was conducted by collecting quantitative data from daily sales, observations of customers and questionnaires. The results show that an asymmetric structure leads to customers being more attentive towards the brand, and perceives it to be more dominant over its surrounding competitors. Furthermore, results indicate that the customer perceived variety increases and we see tendencies to changes in sales..

Identifiering av gallringsbehov med hjälp av flygburen laserskanning :

Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.

Ett kandidatexamensarbete inom lättviktskonstruktioner .

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.

Modulär Mekanikstruktur för Nanosatelliter

The objective of this thesis was to present a design proposal on a modular mechanicalstructure for a nanosatellite. The size of the structure should follow the CubeSatstandards. This standard divides satellites in units (U), where 1U is equivalent to acube where sides measure 100 mm. 2U corresponds to the same volume and size as2 assembled 1U structures, and so on. The focus was to develop a structure in theorder of 3U and 6U.At the integration in the satellite launch rocket, there are a couple of differentinterfaces, where the structure is adapted to common ones; P-POD and CSD.

Konsten att styra konst: - styrning av kreativa projekt inom en nätverksorganisation

This paper describes a case study of the largest film production ever conducted in Scandinavia. The study aims at explaining the complex relationships in the network structure in which the project took place. Coordination of creative projects carried out in a network context, includes handling conflicting interest and contradictions. Creativity needs space and freedom while projects need structure and coordination, whereby controlling these projects becomes complex. Adding to the complexity, does the loose form of organization that the network structure represents, without any long term structure.

Kultur kontra regler : En fallstudie av omorganisering i offentlig sektor

This thesis examines the subject of change in public administration from an instrumental and an institutional structure perspective. The purpose of the thesis is to examine whether institutional structures affect the development of instrumental structures and if it in turn is possible to affect institutional structures by changing the instrumental structures. This case study is primarily based on a series of deep interviews with senior administrators and politicians within two new administrations in the municipality Karlstad, both which have been created by merging several smaller administrations, but also thorough analysis of several official document such as protocols from the municipal council meetings, Tja?nsterskrivelser and internal PMs.   The result of the analysis indicates that both institutional structures and the forming instrumental structures affect each other and  that their ability to affect each other depends on the dominance over the organization each structure has.  In my specific research case we can see that the institutional structure of the city-technical and housing administration has affected the outcome but the institutional structure of the cultural and tourism administration hasn?t.  While the structural change of the city-technical and housing administration hasn?t effected the institutional structure but the structural change of the cultural and tourism administration has affected the institutional structure of this specific administration..

Kapitalstrukturens inverkan på företagsvärdet : - En kvantitativ studie av den svenska aktiemarknaden

Background: During extreme market conditions like the period during fall 2008 the discussion of what affects company value becomes apparent. The capital structure is the relation between borrowed capital and equity in a company´s financing mix. What impact changes in capital structure have on company value is a widely debated subject within the theory of finance. If a relationship between capital structure and company value exists the implication is that an optimal capital structure where company value is maximized also exists.Aim: The aim of the thesis is to study whether a certain relationship between capital structure and company value exists among selected stocks and companies listed on Stockholmsbörsens OMXS30.Implementation: With aim to fulfill the purpose of the thesis regression analysis has been performed among chosen stocks and companies. The empirical results eventuating from this have been analyzed from the view of elected relevant theory.Completion and results: We find that during normal market conditions a positive relationship between debt ratio and enterprise value (EV) can be established.

"Rätt man på rätt plats" - men hur väljer man rätt?

The aim of this thesis is to investigate which the main determinants of capital structure in Swedish listed firms are and to identify which incentives lies behind managers choice of capital structure determinants. Further, the study investigates whether the Post Keynesian theory and theories which incorporate behavioral aspects can be used to explain the capital structure decisions or if the traditional Neoclassical theory give an better explanation. We have used a qualitative method to analyze the determinants of capital structure and the managers incentives behind capital structure decision. We conducted a survey which was sent to 83 Chief Financial Managers and financial executives in Swedish firms listed on Mid Cap or Large Cap. The questionnaire was on-line which enabled for the respondents to quickly and convenient respond.

Broprojektering med 3D-cadverktyget Revit Structure

Det är allt vanligare med 3D-projektering inom byggbranschen för att förbättra och effektivisera bland annat kollisionskontroll, ritningsframställning och mängdberäkningar. 3D-modellering har kommit långt i utvecklingen när det gäller husbyggnad men för mark & anläggningskonstruktion har utvecklingen varit begränsad. Jämfört med traditionella, tvådimensionella CAD-modeller är en tredimensionell CAD-modell uppbyggd på ett annorlunda sätt med objekt istället för ? linjer och streck?. Idag finns det många olika programvaror som erbjuder möjligheten att genomföra 3D-projektering.

Klassifikationssystem på webben: Traditionella och nya

The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.
