Prognostisering av räntabilitet på eget kapital - En jämförelsestudie av tre regressionsmodellers prognosförmåga applicerat på svenska data
A multivariate cross-sectional model is used in this thesis to proxy for expected earnings and to estimate return on equity for 214 companies over the period 2009-2013, using Swedish data. The model, which has never been tested on Swedish data before, is first confirmed to function as a forecasting model for expected return. Furthermore, the model is evaluated through a comparison with two univariate models based on the assumption that return on equity follows a mean reversion process. Forecast accuracy is calculated as the difference of estimated returns and actual returns. The results show that the univariate models' forecasts are superior to the multivariate model's..
Nollföljdsmodellering av transformator-Beräkningar av följdproblem vid ökad kablifiering på mellanspänningsnivå
Historically transformers with system earth equipment have been modeled as open circuits in zero sequence. This approximation has been satisfying, but lately it has been discovered that equipment on one side of the transformer have responded to faults that occurred at the other side. Most of these problems took place when the majority of the system on the secondary side of the transformer contained cables. These findings have led to questioning whether or not the former model of the transformer in zero sequence is correct. This report investigates if it is necessary to represent the transformer in zero sequence in another way than it is usually done today.
Interactive Visualization of Statistical Data using Multidimensional Scaling Techniques
This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.
Interorganisatoriska interaktioner inom Inkubatorer : En studie om kunskapsutbyte och inkubatorsystem
BackgroundIncubators are important facilities for economic growth in society. The main purpose of incubators is to accelerate knowledge intensive firms onto their market by both providing resources and an entrepreneurial environment.Problem Companies within incubators are encouraged to share knowledge and experience with each other with the goal to stimulate development and invention of new technology. This exchange involves interaction on an inter-personal and inter-organizational level. Incubators need to create an open and transparent environment in order to enable this exchange on both levels.Purpose The purpose of this study is to enhance the understanding of how knowledge and experience exchange occurs within the context of incubator systems. By understanding how incubators can capture knowledge and learn from the incubator process, this study can contribute by insights of how the incubator process can be further improved.Method This bachelor thesis is written from an abductive approach and is based on a qualitative case study of Ideon Innovation in Lund.
Vad hör du? : ljudets betydelse för en plats
We are surrounded by sounds. There is always something that makes a sound: a breeze through the leaves, traffic on a distance or your own blood rushing through your veins. Human will always be surrounded by sounds which makes it an important part of our lives. Therefore the sound should have a big influence on how we perceive our surroundings and interpret our world. This essay inquires into what sounds can mean to an open space and urban spaces.
Webfarming : En studie av möjligheter och problem
För att företag skall kunna konkurrera på ständigt föränderliga marknader krävs att de har kunskap om exempelvis kundbehov, konkurrenter och nya produkter. Källor till denna kunskap finns både internt inom organisationer och externt i deras omgivning. Både de interna och externa kunskapskällorna är viktiga, men under de senaste åren har ett allt större intresse riktats mot de externa källorna, då de har blivit allt viktigare för att organisationer effektivt skall kunna hantera sina affärsprocesser.En av de kunskapskällorna som ofta nämnts är Internet och den data som lagras på hemsidor runt om i världen. Dock är det svårt att hitta relevant data på Internet på grund av dess omfattning och dynamiska karaktär. Det har därför börjat uppkomma nya tekniker för att inhämta, strukturera och integrera data från Internet.

Känsloigenkänning i form av ansiktsuttryck med Kinect
Facial expressions are a part of our body language that helps us to clarify the verbal communication between humans. We use our facial expressions every day, both consciously and unconsciously, to express emotions and attitudes depending on the situation. The hypothesis of the study is: Given a facial expression, how well can Microsoft Kinect, as an input method, determine a person?s feelings with the two algorithms Naive Bayes and Sequential Minimal Optimization? The feelings are limited to happy, sad, surprised and disgusted. With the help of Kinect, a person?s facial data, both coordinates of the face and parameterized data, were saved and used for machine learning.
3D PDF
This report is about Adobe Acrobat 3D and their new PDF format witch can contain 3 dimensional models that are interactive. The purpose is to find out if the program and the format work in a level that is suitable for the market. To create this PDF you need Acrobat 3D installed on your computer but it only needs Acrobat Reader 7 or 8 to open it, and the Reader is free to download on the internet.The examination is focusing on four formats: U3D, 3DS, DWG and DXF because they are the most common in the building industry seen from the architects? way. From a 3D model exported to these four formats they where converted to PDF in different settings to be compared in different points as information and size of the files.
En studie inom upphandling av GPD
The Swedish State Road Administration has since 1992 procured operations and maintenance of state roads on the open market. The procurement has been termed ?Grundpaket Drift?, GPD, and comprises mostly operational measures for road networks.The clients of GPD, SRA regions, have gradually changed the original documentation in order to adapt it to local conditions. This process has gradually led to that some parts of the documentation are creating problems for contractors interested in procuring jobs.This thesis tries to analyze GPD and clarify the differences that may be essential to the procurement process and to facilitate future joint working projects and processing descriptions..
Kostnadsutvecklingen inom flottningen i Dalälven 1900-1970
The paper, with a brief summary of timber floating in Sweden and also of some previous re-search in this field, contains a study on costs for timber-floating in the river Dalälven located in central Sweden. The public used timber-floating system in Dalälven and the historical background about this activity is described. The study is focused on the total costs for timber-floating in the public open floating system in Dalälven from 1900 to 1970, the year before the timber-floating was definitively closed down. Also the costs for separating the logs of a specific owner when they reached the point where they could be separated from the timber of other owners are analyzed..

Generationsskräpsamling med explicit kontroll av hårdvarucache
This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory..
Implementation av offline-läge i mobila applikationen GreatRate
Även om de flesta av oss i dagsläget vet att våra mobila enheter kan tappa sina nätverksanslutningar lite då och då har det mer eller mindre blivit en självklarhet att i alla lägen ändå kunna använda våra favoritapplikationer som vanligt. Denna rapport syftade till att hitta en lösning på problemet med nätverksberoende applikationer genom att implementera ett offline-läge som kringgick detta beroende i GreatRate, en iOS-applikation för kundundersökningar i butik. Med hjälp av en databas för att mellanlagra data under tillfällen då en duglig nätverksanslutning inte fanns tillgänglig samt synkronisering av nämnda data när anslutningen åter blivit funktionell förväntades problemet kringgås. Resultatet blev som väntat en applikation som gav användaren en förhöjd användarupplevelse helt oberoende av nätverksanslutningens status. Några av slutsatserna som drogs var dock att flera olika lösningar finns för detta problem och att problemet högst troligt har olika utseenden för olika applikationer..
