In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

This study investigates how social interaction affects newly arrived pupils? views on their study situation in the Swedish educational system. The aim is to give a contribution to the discussion on the notion of including ?the Other? in educational practice in multicultural schools. Semi-structured group interviews were conducted to explore how the intercultural perspective and the theory of inclusion can be used to explain the dynamics of social interaction.

Costs of maintenance on combines are a subject of interest thus it constitute a large investment and cost for the individual farmer. Therefore it is important to have up to date knowledge and the right facts to be able to do reliable calculations on one of the largest investments for a farmer. The aim of this study was to compare costs of maintenance on combine/threshingmachine with the computer program for advising environmental issues in agriculture, STANK. Interviews took place and data were collected by handing out questionnaires to 20 farmers. A similar study conducted by Neuman (2003) investigated costs of maintenance and compared these with STANK. The results of this study have also been compared and examined related to data from SLA - Skogs och Lantarbetsgivarförbundet. The result shows that 18 out of 20 combines were given a higher cost of maintenance when using STANK compared to the numbers in this study.

The aim and research questions of this study are concerned about how, and what kind of, problems and subjects that citizens raise during verbal interaction with politicians and officials in the field of participatory democracy. The theoretical framework of the study dominates by theories with a positive approach towards participatory democracy, but there is also a broader discussion on the phenomenon?s strengths and weaknesses.The case in focus of the study is a specific phenomenon of participatory democracy created by the municipality of Växjö. The empirical material that is analysed is consisted of written text based on the verbal interaction from these meetings between citizens and politicians/officials.The outcome of the study shows that most of the verbal interaction was held between citizens and politicians/officials in a vertical direction and that a major part of the responsibility concerning the raised subjects is estimated to be in the hands of the latter part. In the light of under what circumstances the meetings are practised, the democratic and collective minded performance of the citizens is argued to be in good condition, despite the dominating vertical interaction and estimation of trust..

The aim of the thesis is to explore how the human subject is depicted in contemporary posthumancinema and how these films effect our comprehension of human subjectivity. The object of analysis isJames Cameron?s Avatar (2009) and the method of analysis is cybernetic and intermedial. The conclusionis that Avatar is a film that depicts a posthuman network society where existence and subjectivity in a greatvariety of forms is possible. The film presents posthuman subjects in symbiosis with avatars, terminals,extensions and prothesis.

The Master Thesis work this report is based upon has been conducted in cooperation with Svea Teknik AB. Svea Teknik is a consultant firm which is developing parts of a tunnel boring machine on behalf of Atlas Copco. The machine is being developed to mechanically excavate hard rock by fixating itself in the tunnel and then press a large rotating cutter-wheel equipped with disc-cutters against the tunnel wall. The disc-cutters are the tools that are in direct contact with the hard rock and are therefore exposed to extensive wear and needs to be replaced on a regular basis.The purpose of this Master Thesis has been to develop a service equipment that will enable time effective and safe changes of disc-cutters. The disc-cutters have a diameter of 17 inches and weigh about 130 kg.

The fundamental freedoms and human rights is something the countries, and its citizens, of theEuropean Union more or less take for granted. However, in recent years these rights have become atopic of discussion in the way that a debate about the Islamic headscarves has developed. Thisdebate has resulted in that a number of countries, including France, have taken legislative measuresto ban clothing that fully covers ones face. Out of these bans a discussion has arisen concerning thefundamental freedoms and human rights. These burqa bans, as it is labeled in the pubic debate, havebeen accused to wrongfully limit the individuals freedoms and human rights.This study therefore has the aim to analyze these burqa bans in relation to the European Union,United Nations and the Council of Europe?s general declarations concerning the fundamentalfreedoms and basic human rights.The main result of this study shows that these bans in fact is not a proportionally restrict in thefundamental freedoms and human rights.

The research in this paper aims to producing a home version machine thatcan dry and make biological waste into compact pellets. This product ismade primarily for those who want to improve the environment and reducethe energy consuming process of separating the biological leftovers fromother waste in the large processing plants and save money due to reducedpickups of waste. Since there is no commercially available product thatdoes what we want to achieve we had to start from the beginning with boththe design and the mechanical aspects. The result is a machine, that fits inour homes, and in an easy and inexpensive way reduces the amount ofbiological waste that needs to be collected by the public wastetransportation system. This is done without reducing any of the energy inthe waste and it can still be used to compost or by large-scale plants that usethe waste to make electricity.

In today?s archaeology there?s a growing need for non-invasive prospection methods. However there?s a methodological gap and what?s missing is a method for locating human bones. In this study a specially trained German shepherd is put through scientific tests determining how good the dog is at telling the different between the scent of human and animal bones.

As artificial intelligence (AI) has gained more influence in recruitment, both recruitment processes and the role of the recruiter are changing. This study aims to describe and analyze how recruiters translate, use, and relate to AI in their work. Through a qualitative method based on semi-structured interviews and document analysis, the study explores recruiters? experiences, attitudes, as well as perceived obstacles and opportunities regarding the use of AI in recruitment. With a theoretical foundation in translation theory, fashion, and imitation, the study examines how AI is not only followed as a trend, but also shaped and adapted locally through translation, depending on organizational identity and needs.

Human Computer Interaction (HCI) is a broad discipline that studies different concerns regarding interactive systems? development. One of the major interest points within the discipline is the reasoning behind building specific functionality into computers and the long-term effects that usage of systems will have on humans.Within Human Computer Interaction there are theories and frameworks how to involve a user in the process of developing new systems. In this paper focus is applied to the development process within developing applications for Enterprice Digital Assistants (EDA) and to what extent the end-users are involved in the process. Fazer Bageri AB has been choosen to represent a business corporation that uses handheld computers in their everyday tasks.The method used to gather information for this study has been by performing interviews and observations with key stakeholders at Fazer Bageri AB and MobiOne AB.

In this essay dog as a compatible model were put against human. The major histocompatibility complex (MHC) genes were compared between dogs, human, cat and mouse. To evaluate dog as a model and study similarities and differences was the aim with this review. Dog as a model contributes to understand mechanisms behind autoimmune diseases and showed clearly histological similarities between human and dogs concerning the skin disease mucous membrane pemphigoid (MMP)/cicatricial pemphgioid (CP). Further genetic evidence motivated the choice of using dog as a comprehensive model when the MHC-complex correlated with hypothyroiditis in Doberman dog as it does in human. Physiological similarities with low levels of thyroid hormones (T3 and T4) together with high level of thyroid releasing hormone (TSH) were found in the same way as in human.

The aim of this essay is to discuss the meaning of the human and its possible overcoming in Friedrich Nietzsche?s doctrine of the eternal recurrence of the same, with Martin Heidegger?s readings of Nietzsche as point of departure.According to Heidegger, Nietzsche?s doctrine of the eternal recurrence of the same represents the end of occidental metaphysical thinking. The thought concludes a thinking of being as the presence of beings, where the original question of being was never developed out of its own ground.But at the heart of this interpretation, often considered ?violent?, lies the question of whether man is able to think being out of his finitude. This is the question I will unfold, through a reading of Nietzsche?s thought of the eternal recurrence of the same, as it is presented in his Thus spoke Zarathustra, as an attempt to think beings in their being beyond a ?humanization? of them, expressed in transcendental aims, purposes and categories.
