Furthermore, we analyses terminal and applied information technology.

Kvartalsvisa resultatmönster : En studie av nordiska börsbolags tendenser till resultatmanipulering

Uppsatsen undersöker om kvartalsvisa resultatmönster kan indikera potentiellt användande av resultatmanipulering (eng. earnings management). Företag klassificeras som Negativa-Positiva- (NP), Positiva-Negativa- (PN) respektive kontrollföretag beroende på hur resultatförändringar ter sig över ett helår. Med hjälp av den modifierade Jonesmodellen beräknas därefter företagens godtyckliga periodiseringar för att undersöka om NP- eller PN-företag är mer troliga än andra företag att tillämpa periodiseringsmanipulering. Ytterligare undersökningar genomförs med fokus mot faktisk resultatmanipulering (eng.

Experimentell spelmekanik - Realtidsaction m oter turbaserad strategi

In the gaming industry, it has long been popular to combine genres with the aim ofcreating games that bring together the best of several worlds. However, there are stillmany unexplored combinations with good potential.This report addresses the planning and development of a game prototype that combinestwo game genres, turn-based and real-time strategy. In addition to presenting the results,the report also discusses the di culties that were encountered and how they were handled.The prototype contains a working combat system and a basic AI. The prototype ismodular, which means that it is easy for an end user to extend the game with extra content.Most elements that were considered important from the two genres were implemented, butthere is still room for improvement and further development.The result is evaluated by means of quality assurance, a process that is commonly usedin the gaming industry. The response has been generally positive, which indicates thatthe combination has potential and should be explored further..

Bildregistrering i teorin och praktiken: Mid-Manhattan Picture Collection och Kungliga biblioteket.

This thesis presents a comparative study of image registration at two picture collection libraries. The two registration systems are analyzed as to the theoretical principles behind them and their practical application, and related to theoretical tools for subject analysis and bibliographic standards. While a growing number of picture collections now digitize their material, generally accepted standards and methods for the registration of digital images are still lacking. Many different systems coexist, often developed in-house in response to ad hoc needs and based on traditional registration tools created for textual documents, resulting in internationally incompatible mixed-format systems. The two picture collections examined here, however, have opted for similar, standardized tools for registration and subject analysis, and while there are differences in their application and focus, they have both considered issues of cross-system compatibility.

Pedagogisk samling i förskolan : En kvalitativ studie om förskollärarnas tankar kring samlingens betydelse för barns språkliga och sociala utveckling

The purpose of this study is to examine how pre-school teachers think about the importance of circle time in regard to the child's language and social development from a sociocultural perspective. Furthermore the study will include what role the educators? have during the circle time.To answer our purpose we have chosen the following question:What is the role of the teachers in the circle time?What are the teacher?s thoughts about the circle time?s importance to children's social development?What are the teacher?s thoughts about the circle time?s importance to children's language development?The study is constructed on qualitative methods, where we conducted structured interviews with six preschool teachers and observed their circle time to collect our empirical material. The study is also based on Vygotsky's sociocultural perspective which says that all learning takes place through relations and interaction with other people in the cultural context you are in. The results have shown that pre-school teachers are aware of the circle time?s importance to children?s development, and purposely plan the circle time to give children the opportunity to develop both socially and linguistically skills..

Optimerad bildsökning ? Bör vissa egenskaper prioriteras vid sökning efter en viss kategori av bilder?

As the information society becomes increasingly flooded with digital images, the need for efficient image retrieval systems increases as well. To handle the vast amounts of data involved, the indexing process needs to be run automatically, using content-based descriptors extracted directly from the digital image, such as colour composition, shape and texture features. These content-based image retrieval systems are often slow and cumbersome, and can appear confusing to an ordinary user who does not understand the underlying mechanisms. One step towards more efficient and user-friendly retrieval systems might be to adjust the weight placed on various descriptors depending on which image category is being searched for. The results of this thesis show that certain categories of digital images would benefit from having extra weight assigned to colour, texture or shape features when searching for images of that category..

Jämförelse av frånluftsvärmepumpar

In order to reach the environmental targets, set up by the EU, there are many measures taken to make Sweden more energy efficient. In the housing and real estate sector, an installation of an exhaust air heat pump that reuses the heat in the exhaust air in order to lower the amount of acquired energy, is an example of such an action. The recovered energy can then be used for heating of radiators and tap water. This report aims to evaluate and compare three different systems using exhaust air heat pumps regarding COP, degree of coverage and cost savings. This study was delimited to only account for apartment buildings.The theory chapter describes the different conditions and factors that affect a building?s energy balance.

Effektivisering av energianvändningen i en förskola

This rapport contains an examination of the energy consumption of a kindergarten, which areas that have the largest impact on the energy consumption and what can be done to reduce those areas in ways that are relatively easy and profitable. It is also analyzed if it is possible to reduce the energy consumption from today?s consumption to a consumption that fulfils the demands placed on low energy houses by FEBY.The focus has been on reducing the energy consumption of the areas ventilation, heating system and hot water system, since those seemed to be the easiest ones to affect and since the building is quite recently built.There are different kinds of ventilation systems, at the moment the building have a CAV-system, which means that the ventilation is too high during large parts of the day. There are different ways to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this system.

Säkerhetsklassificering av dammar : En kartläggning av system i Sverige, Norge, Finland, Schweiz, Kanada och USA

In a comparing survey this thesis investigatesclassification systems for dams in Sweden, Norway,Finland, Switzerland, Canada and USA. Theinvestigation is aiming at an understanding of howpotential consequences of a dam failure are takeninto account when classifying dams. Furthermore,the significance of the classification, regarding therequirements on the dam owner and surveillanceauthorities concerning dam safety is considered andreviewed. The thesis is pointing out similarities anddifferences in the line of dam safety.The survey of dam safety is firstly based upon legalrequirements in the different countries andsecondly on guidelines regarding dam safety. Damowners generally are ultimately responsible for thesafety of their dam, and often have their ownroutines regarding how this safety is to be achieved.In this thesis, however, the legal requirements aremainly focused upon.The investigation has resulted in an outlining ofeight areas, where the classification systems in thevarious countries have been compared.

Hackerör på Sydsvenska höglandet : vad skiljer röjningsröseområden från celtic fields, stensträngsområden och bandparcellområden?

From the pre-Roman and Roman Iron Age, a number of different fossil agrarian landscapes can be found in southern Sweden - clearance cairn areas, celtic fields, stone-wall complexes and geometrically laid-out strip fields. With two different comparative analyses, this paper tries to explain some of the differences between clearance cairn systems and the other fossil field systemsThe shape of the early Iron Age agrarian landscape varies between different provinces of southern Sweden. At Gotland, celtic field systems were laid-out before 500 BC. In Småland at the same time, areas with clearance cairns were created. How can the difference be explained? The different physical appearance of clearance cairn areas and celtic fields can be explained by the different ways to handle the ard in till and in sandy soil.

The thesis is the final course which ends a three-year mechanical engineering program with focus on technical design.The thesis started in an operation which electricians are exposed to every day. The operation in question is cable laying or wiring. The tool they use is called a tension spring and is a long and stiff wire, usually made out of nylon or fiberglass. The tension spring is fed through pipes in the walls and brings the desired cables with it on the way back.

The economic consequences of Striga hermonthica in maize production in Western Kenya

Kenya is a country of 35 million people and is situated in Eastern Africa. 70% of thepopulation works within the agricultural sector and for many of them food insecurity is amajor problem. Maize and beans are today the staple food for many households. Goodfarming conditions enable two harvests per year and a potential maize yield of 4-5 tons perhectare.A major problem for many farmers in this area is the increase of the weed striga. The weedcauses severe yield losses, and has a major economic impact on smallholders.

Skolgård : Ett pedagogiskt verktyg för fritidspedagoger

The present study aimed to replicate Tversky & Kahneman's' survey of 1981 The Asian Disease Problem. A survey was conducted on the Internet (N = 200). An identical problem was added, yet with The Swine Flu as the disease. This was done to be able to investigate if there are any order effects, and also if it matters whether the mentioned disease is fictional or real. The results show the same results as Tversky & Kahneman already noted; positively and negatively framed problems generate different responses from the participants.
