Simulering av värmebehov för kombinerad kontors- och laboratoriebyggnad utan traditionellt värmesystem
In this Thesis the possibilities of designing a larger building that is very energy efficient in the sense that it would not need a conventional heating system are discussed. Solar radiation transmitted through the windows, internal heat from occupants, lamps and electric appliances inside the building and heat recovered from the ventilation system then have to be sufficient for the heating of the building. This study is of general interest since the property company, Akademiska Hus, plans to use this study as a first step in determining if this technique could be used in the future and thus be worth further investments. A building without a conventional heating system of the size investigated in this project has not yet been built.The energy needed for the heating of the building was simulated using VIP+.The conclusions from the study are that it is possible to build large buildings without any conventional heating system. This could be achieved in many different ways, for example by lowering the inside temperature or by using better windows and heat recovery system with higher efficiency.
PRODUKTIVITET N?R ARBETET BEDRIVS P? DISTANS med inslag av social n?rvaro och motivation
This study investigates how productivity works when employees have remote work in their workplace. This study will also focus on challenges that cause productivity to decrease when remote work applies. The empirical data shows that individual productivity increases when employees work in a workplace that provides remote work. The data says that less distractions and high autonomy is a big factor to why employees feel that they work productively at home. Briefly it shows that a flexible workplace makes individual employees work productively and even motivates employees to work effectively because of increased concentration and undisturbed work environment.
Högfrekventa tryckvariationer under de senaste århundradena
Long time-series of pressure measurements often have high quality because the early instrumentsare more or less the same as the modern ones. A time-series from Lund consisting of three dailymeasurements from 1780-1997 has been homogenised and is therefore suitable for analysingpossible influences of the enhanced greenhouse effect. According to a two-layer model of theatmosphere one finds a shift in the frequency of baroclinic instability due to an increasedtemperature gradient caused by the increasing CO2. Baroclinic instability over the Atlantic Oceanis the main cause for frontal zone production, causing cyclonic activity over the southern part ofScandinavia. Changes to the baroclinic instability would therefore be traceable in the time seriesfrom Lund.
ABL:s utvidgade värdeöverföringsregler då ett aktiebolag är komplementär i ett kommanditbolag : Utgångspunkt ur NJA 2014 s. 604
This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.
En oviss framtid. Vart går allmänheten idag för att uppleva och lära sig historia och vart går den imorgon?
The purpose with this paper is partly to find out what people of different ages do to learn more about the past, and partly what they believe will happen within the next 50 years with institutions like traditional museums and the relatively new theme parks. How will the museums and theme parks evolve? Will they evolve? Or will they disappear?To solve these questions I have sent out a questionnaire to people of different ages. I have also been in contact with employees from different museums and theme parks in Skåne. I have used literature written by archaeologists among others.
Shape from Silhouette Scanner
The availability of digital models of real 3D objects is becoming more and more important in many different applications (e-commerce, virtual visits etc). Very often the objects to be represented cannot be modeled by means of the classical 3D modeling tools because of the geometrical complexity or color texture. In these cases, devices for the automatic acquisition of the shape and the color of the objects (3D scanners or range scanners) have to be used. The scanner presented in this work, a Shape from silhouette scanner, is very cheap (it is based on the use of a simple digital camera and a turntable) and easy to use. While maintaining the camera on a tripod and the object on the turntable, the user acquires images with different rotation angles of the table.
Interpretation och dissonansbehandling på kromatisk nyckelharpa
By describing and analyzing a self made composition for the Swedish folk music instrument ?nyckelharpa? with emphasis on playing techique, dissonance treatment and interpretation questions are reflected upon regarding how dissonances and andvanced harmonical progressions are treated on a limited instrument such as ?nyckelharpa?. By emphasizing the traditional norm connected to the interpretation and instrumentation of traditional Swedish folk music (a traditon in which the nyckelharpa is included) and comparing the te- chniques connected to it with the recent composed material in a western classical context the possibilities and limitations in composition and interpretation are further investigated. Thus the musical experience and the documentation of the process of composing a concert for nyckelharpa provides a knowledge base for reflective analysis upon questions regarding interpretation, composition and dissonance treatment. This thesis also provides a brief summary of traditional playing and bowing technique as well as a short historical description of the Swedish traditional instrument ?nyckelharpa?..
FPGA-design av en STDM-baserad multiplexer för seriell multiprotokollskommunikation
The remotely operated underwater vehicles that the client develops have needs of different kinds of data channels. In order to minimize the need of physical cable between the control unit and a ROV, a multiplex protocol has been developed. The protocol has been designed with the aim of using the bandwidth of the transferring link as efficient as possible.The different kinds of data channels used during this thesis project is; RS232, RS485 and CAN. ROM and FIFO-memories have been used to be able to effectively manage the different data channels. All the reading and sending of these channels have been implemented in FPGA-technology, the coding is made generic so that it will be easier to add more channels to the system in the future.The multiplex protocol is a modified version of the method STDM and it is a proprietary protocol.
Ny bebyggelse på Almöstrand - Planering av bostadområde i kuperad terräng
Tjörns kommun har planer på att bebygga Almön, en halvö belägen på nordöstra Tjörn intill Tjörnbron. Projektet är avgränsat till området som benämns Almöstrand, vilket är Almöns västra strand, en kuperad sluttning med kraftigt lutande partier som idag till största del består av skogsmark. Syftet är att undersöka hur man på olika sätt kan planera vägsträckningen i området, samt placering och utformning av hus, med hänsyn till en rad olika parametrar. Undersökningen visualiseras slutligen i 3D, i form av renderingar från Revit Architecture samt en fysisk modell.Initialt genomfördes en utredning för att ge beslutsunderlag till projektet. Vidare gjordes en fallstudie vilken har använts som referens och inspiration till arbetet.

Det här arbetet innefattar webbtillgänglighet med avseende hur väl ett antal utvalda universitet och högskolor följer de riktlinjer för personer med läs- och skrivsvårigheter. Problemet med att inte ha en webbtillgänglig webbplats är att en stor grupp av personer som går miste om innehållet. Det är dessutom inte bara personer med läs- och skrivsvårigheter som blir drabbade, utan det är även personer med andra livssituationer som drabbas. Syftet med arbetet är att ta fram rekommendationer och finna lösningar som gör att universitet och högskolors webbplatser blir tillgängliga för alla. Analysen som görs i arbetet är baserad på W3C WAI:s riktlinjer om tillgänglighet och är avgränsad till användare med dyslexi.
Statistisk analys av partiella urladdningar
This thesis concerns partial discharges in stator windings and the possibility of analyzing data using statistical methods. Partial discharges, or PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity is. A technique to measure and analyze PD that has become very popular over the last few decades is phase resolved PD patterns.
Elmontörernas syn på elsäkerhet : En studie om att öka elsäkerheten i Telge Nät AB
In today?s society, safety in a workplace is an important factor to any organization. Focus on improving the working conditions by making them safer through technology is taking us into a time where we rely on technology to keep us safe. How well developed the technology may be, it is still not enough to keep us entirely from harm. Human error will always be a factor in the human interaction with a workplace.
The effects of Joint Ventures announcements on stock returns behaviour - An Event Study of the Stock Market
The purpose of this study is to examine the effects of joint venture announcements on stock prices behavior and simultaneously to test the German stock market (Frankfurter Wertpapierbörse) for efficiency. We tried not only to analyze the general impacts of a JV-announcement but also to look for differences in the market response to announcements of different types of joint ventures, namely: domestic, international, horizontal and vertical. Our expectations of efficient market were confirmed during our paper, which employed the technique of the standard event study. The calculation of abnormal returns which are the signals for market efficiency or inefficiency respectively were based on the market model, establishing linear relationship between the return on the market and the return on an individual security. The parameters of the model were obtained through regression analysis..
