RFID på Kvarntuna stadsbibliotek : Teknikskifte som möjlighet till förändrat arbetssätt?

This two years master's thesis in Library and Information science, examines how the implementation of new technical equipment can affect how staff in public libraries organize their work and activities in the library. One Swedish public library in specific is the subject of research in this thesis, which has been anonymized as Kvarntuna city library. The study takes place in the beginning of the implementation of RFID-technology in the library. RFID, which stands for Radio Frequency Identification, is supposed to make the handling with different types of media in the library more Efficient and in connection with the implementation one wants to reorganize work and activities in the library to make it even more Efficient and also create a modern library.The thesis' method is qualitative interviews with six members of the staff. The theoretical framework of the thesis is a sociocultural perspective, especially inspiered by Roger Säljö, a Swedish professor in pedagogical psychology.

Kvantifiering och kartering av föroreningstransport inom ett avrinningsområde

The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most Efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..

PlusTak

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more Efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

Delta X : Utveckling av värmeväxlare

Stockholms vattenskärning AB in Kungsängen has through the acquisition of a company begun to design and produce aircraft heaters whose origin is early 1970s which follows a high inefficiency in terms of energy consumption and size.The aircraft heater, which is sold worldwide, serves its purpose for customer satisfaction and has done so ever since it was developed in the 70s.Stockholms vattenskärning AB is now investigating the possibility in making the aircraft heaters more Efficient, both in terms of energy consumption but also on a more Efficient design with the belief that it would lead them to an edge in the market. The aircraft heater consists of several main components whose function altogether is to keep passenger aircrafts warm while they are on the ground.This project has been limited to the further development of the heat exchanger package which accounts for the conversion of the hot medium to the fresh air being carried in to the aircraft cabin. Work has been divided into different phases in order to create a better understanding of the project range and to make it easier to divide the various elements in the time available, 10 weeks. These phases are literature review, situation analysis, concept generation, CAD, concept comparison and writing reports.After the initial literature review was made, a fundamental theory was written which is essential in understanding the remaining parts of the project.With the theoretical part as support, measurements and calculations were made on the current heat exchange package in a situation analysis to ensure its operation and efficiency.In the concept generation phase, the collected facts from the literature review was used as the basis for creating a matrix. The purpose of the matrix was to indicate the two most suitable types of heat exchangers to develop four new concepts out of.In the CAD phase the four concepts was drawn up and then described with text and images.The last phase is the concept comparison where a concept selection matrix is used to function as a decision basis for further production at Stockholms vattenskärning AB. The four concepts have been developed based on the current heat exchanger and is gradually changed into a design of a cross-flow heat exchanger constructed out of stainless sections. The purpose of this is to have gradual upgrading of the heat exchanger as an option, in order not to saturate the market..

Vana texturerare : En uppsats om minsta motståndets väg, invanda mönster och liknande gränssnitt

This essay brings up how experienced texture artists in game development can get comfortable in their workflow and therefore not spend time on learning new techniques that in the end could be more Efficient. We base this on theories that people often choose the path of least resistance, which in the case of an experienced texture artist would be the path they have learned and are comfortable with. We also talk about the popularity of Photoshop and that many of today?s texture artists in the game industry are using it and that this could be because Photoshop was one of the first programs that could be used well for texturing. Because of this many learned to use it and stuck by it and then taught Photoshop to new texture artists because that is the program that they know.

Sammanfogning av videosekvenser från flygburna kameror

The usage of Unmanned Aerial Vehicles (UAV) for several applications has in-creased during the past years. One of the possible applications are aerial imagecapturing for detection and surveillance purposes. In order to make the captur-ing process more Efficient, multiple, cameraequipped UAV:s could fly in a for-mation and as a result cover a larger area. To be able to receive several imagesequences and stitch those together, resulting in a panoramavideo, a softwareapplication has been developed and tested for this purpose.All functionality are developed in the language C++ by using the software li-brary OpenCV. All implementations of different techniques and methods hasbeen done as generic as possible to be able to add functionality in the future.Common methods in computervision and object recognition such as SIFT, SURF and RANSAC have been tested..

P/E-effekten : En utvärdering av en portföljvalsstrategi på Stockholmsbörsen mellan 2004 och 2012

One could argue that the most discussed topic in finance is whether or not it is possible to ?beat the market?. Even though many people claim to do this, there is little evidence to support the idea that one can consistently beat the market over a long period of time. There are indeed several examples of investors who have managed to outperform the market consistently for a long time, but the efforts of these individuals or institutions could by many be considered to be pure luck.One of the many strategies that have been evaluated by several researchers and is said to generate a risk adjusted return greater than that of the market, is one based on the P/E-effect. This strategy is based on the financial ratio P/E ? price divided by earnings ? and used by constructing portfolios consisting of stocks with low P/E ratios.

Indexeffekten : En studie gjord på Nasdaq OMXS30 och OMXH25

AbstractMaster thesis in Business Administration, School of Business and Economics at Linneaus UniversityAuthors: Patrik Larsson and Pontus GislénSupervisor: Håkan LockingExaminer: Sven-Olof CollinTitle: The index effect- a study on Nasdaq OMXS30 and OMXH25Introduction: A significant part of the financial literature is based on the Efficient Market Hypothesis which assumes that prices in the market reflects all available information. Anomalies, such as the index effect, indicate weaknesses in this theory as it has been proved that it is possible to outperform the market using public information. Hence, the index effect can be linked to market efficiency which makes it interesting to study from a theoretical perspective. The mapping of the index effect is also interesting from a practical perspective, as it leads to a better understanding of whether investors and firms should take this anomaly into account.Problem: Is there an index effect, how does it behave and what can explain this effect?Purpose: The aim of this study is to investigate the index effect.

Ekonomistyrning inom äldreomsorgen, Intraprenad eller entreprenad - är det någon skillnad

In recent years the elderly care in Sweden has gone through several structural changes with the main purpose of delivering a more Efficient service. The aim of this study is to compare the management control system in a privately and a publicly managed elderly home. A qualitative study was conducted which included interviews, observations of meetings and reviews of relevant documents. To be able to identify possible differences the framework of Hood consisting of seven dimensions was used. An analysis of the selected dimensions showed that the differences in management control were minimal and Brunsson's theory of politicization and 'company-ization' were used to explain why..

Therefore a subsidiary aim is to analyze how this influences the prospects of reaching the objectives. The work consists of two parts; a case study and a comparative literature study that focus on England, the Netherlands and Sweden. The case study is intended to provide a practical perspective through a comparison of the climate impact from two methods.

Virtualiserad testmiljo? : Utva?rdering av virtualiseringsprogramvaror

Virtualization has increasingly been adopted in the last decade and the usages of virtualized environments are going to be an important part of how computers are used in the nearby future. There are a lot of advantages with virtualization and different methods have been developed to make it as Efficient as possible.Forsmarks Kraftgrupp were interested in the possibility of taking advantage of virtualization in their testing environment.In this report, hypervisors of type 1 and type 2 and containers have been evaluated to determine which method and what program is preferable on a server cluster of four HP ProLiant DL380 Generation 4. Because of the hardware specifications of the DL380, focus has been on virtualization programs that do not require hardware assisted virtualization.The results show that it is possible to use some of the type 2 hypervisors on the HP ProLiant DL380 Generation 4. The suggested virtualization programs are VMware Workstation or Oracle VirtualBox. .
