Proviant - sparar hushållets pengar på ett miljövänligt sätt

The Smart Grid technology has during the last decade been established as a way to create a greater flexibility on the electricity grid that will be needed as the development moves towards an increased share of renewable primary energy sources in the electricity production. One part of the Smart Grid technology is the ability to shift loads in time, to adapt to either price or emissions, known as Demand Response. This project, which was conducted at KTH in collaboration with the consulting corporation Capgemini, examines the economic, environmental and social aspects of the Demand Response technology. In the project, three household products are used in a model that derives the potential savings in costs and emissions of CO2e. The results show that the actual savings measured in SEK are small, but that the savings measured in percent can be as high as 20 percent. Reduction of CO2e emissions is slightly lower.

Karaktärisering av hästerns gångarter med accelerometerteknik

In today?s horse keeping, there is an increasing awareness of the importance of movement and activity for the horses comfort and tenability, while tradition has it that horses should be kept in boxes and small paddocks. In order to develop housing systems that fulfils and optimizes the horses needs regarding movement and activity, we need to know more about factors that influence the activity patterns of horses. A first step is to be able to record and analyze the gaits in horses with an automated system. This could be done by use of accelerometer data.In this pilot study, existing accelerometer technique was used to characterize the different gaits in horses (walk, trot and canter) by studying how their respective signal patterns differ and how this is influenced by the size of the horse.The accelerometers being used in this study measures the movement in three different spaces; horizontal, lateral and vertical.

Synkronisering med SyncML

The last couple of years the use of mobile devices such as mobile phones and PDAs has increased tremendously. Most of the these devices have their own protocols for synchronising data and this has given rise to a need for a standard synchronisation protocol, SyncML. This thesis compares this protocol against the existing ones. The comparison shows that the preferred choice is SyncML. Also an application using SyncML has been developed.

Evaluation of specificity of a walnut antiserum and detection of English walnut (Juglans regia) in food with ELISA and Real-Time PCR

Nuts of all kinds are common ingredients in food. For nut allergy sufferers the frequent use of nuts cause problems and "hidden" nuts in food products may elicit allergic reaction when such foods are consumed. Methods for detecting and quantifying walnut (and other nuts) with high sensitivity and specificity are therefore very important.The objective of this project was to verify the specificity of a rabbit antiserum against walnut with immunodiffusion and to determine the size of the dominant walnut antigens with Western blotting. In addition, a commercial sandwich ELISA for walnut quantification was validated and compared with a qualitative real-time PCR.The rabbit antiserum proved to be less specific but after absorption with cross-reacting nuts and seeds it showed high specificity. The ELISA kit reacted, except for walnut, with pecan and slightly with other nuts and seeds tested.

Utveckling av metoder att mäta centrering av skruvhål i skär

There have been, in some rare cases, difficulties with clamping of inserts with U-holesin their tool holder. According to the complaints, the inserts could not be properlyclamped or could fracture when clamped. A study has shown that variations inclamping behaviour are mainly depending by the position of the screw hole in the toolholder and the centering of the screw hole in the insert.The focus of this project has been the centering of screw hole in insert. It has beenshown that the screw holes are not always enough centered in the insert. Theproblem may occur after a certain step in the production, i.e.

Glasklart? En kvantitativ studie om en inglasad exponerings påverkan på kunden

Shoplifting is a serious problem due to the fact that about 2 % of a retail store's turnaround dis-appears annually. This paper discusses the problem with shoplifting where a closed retail display of glass can prevent this kind of misbehavior. Hitherto the scientific research regarding how consumers react to a closed retail display is non-existing. With this in mind we want to investigate and enlighten the phenomenon regarding consumer behavior and product appreciation. The study is carried out at a retailer in the beauty industry in Sweden both in stores where the selection of perfumes have been displayed behind glass and in stores in which they have been displayed with open access.

Utveckling och konstruktion av växellåda för elektroniskt styrda ställdon

The task of constructing a transmission has been provided to us by Digital Engineering, which is a company located in Hovmantorp. After meeting with Digital Engineering we started immediately with the brainstorming to find different ideas with pen and paper. After having presented a number of concepts for the company, we had finally chosen a winner. For the gearbox to be able to work in a good way the tension must never exceed the strain limit of the material. A prototype of the gearbox was produced by TKB Modell.

Spindeln i nätet : En kvalitativ studie om skolkuratorers möjligheter och hinder i arbetet kring elever som har föräldrar med alkohol- eller annat drogmissbruk.

The aim of this essay was to describe how school social workers can help and support students with parents who abuse alcohol or other drugs. We wanted to see how school social workers room for action is presented and how it affects their work with students living with parents who are abusing. We used a qualitative method to elucidate how school social workers handle this issue in a more profound way. By conducting semistructured interviews with six school social workers in one province in southern Sweden we gained exhaustive and detailed answers. In the analysis we used street level bureaucracy and theory of recognition.

Bärare av mat : Arbetsfördelning och könsskillnader i restaurangbranschen utifrån ett genusperspektiv

The distribution of work related tasks depending on gender leads to different appraisal depending on which gender is performing a task. This aim of this research is to study how gender differences influence task allocation within the restaurant industry. The study is inspired by a discourse analysis perspective complemented by constructivist and critical pragmatic theory. Interviews were conducted in two focus groups with seven participants in total. The analysis is divided into four sections which answer six discourse analytical questions using the interview material.

Sekularism och politisk islam. En analys av antagonismen mellan två diskurser i Turkiet - den kemalistiska och den islambaserade

This paper concerns the divide between secularist and anti-secularist groups in Turkey, which is related to a greater antagonism between a Kemalist and an Islamic political discourse, dominant in Turkish politics since the 1980s. The main aim of the paper is to analyse the causes of the conflict using the discourse theory of Laclau and Mouffe. The second aim is to analyse the contents of each discourse and identify the main points of conflict between them. The empirical material used in the study consists exclusively of secondary sources treating the topic, and these are analysed using the theory of identity conflicts, which is part of Laclau and Mouffe's theory. It will be argued that the attempts of Kemalism to impose strict secularism by hegemonising the concepts of ?modernity? and ?Islam? led to the creation of an alternative political discourse based on political Islam.
