Design och implementering av ett webbaserat personalhanteringssystem
Quickmatch is a company that recruits students to other companies that need temporary workers. Today all administration is done by hand, which is very time demanding and therefore inefficient. Employees send assignment reports by e-mail about the working hours and breaks to the administration office. Since these reports are handled manually, there is a great need for an automated system that makes the company more scalable.The purpose of this work was to solve the defined problem, i. e.
Konstruktion av datainsamlingskort för mÀtsystemet COMET
During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.
Cupsystemet : En kvalitativ fallstudie av en mobil webbtjÀnst
The thesis describes the following main question: Will the administrative labour during football tournaments be made easier with the help from a mobile web service or will it convey to unnecessary extra work? To be able to give a good and qualified answer to this question, the thesis will in the beginning describe how the technique for such a system might look like and also describe the existing administrative moments during a football tournament, this is too give the reader a deeper understanding for further reading. The thesis then goes on to describe a concrete system which is tested on three football tournaments. On the basis of the tests, interviews and through analysis of these the thesis will be able to answer our questions. The result which we present in the thesis have unfolded through testing of the system on three chosen football tournaments.
Spelfilm i historieundervisningen : Nio lÀrares anvÀndande av spelfilm i historieundervisningen samt en analys av praktiskt, pedagogiskt anvÀndande av en spelfilm
The main purpose of this C-essay is to answer the question: What have been the consequences and effects of the merit point system on language studies and the parties concerned (teachers, students and principals) during the school year of 2010/11?The merit point system is the result of a political decision and was implicated for the first time in the Swedish upper secondary school during the school year 2010/2011. Being a completely new phenomenon it is of great interest and importance to study its effects.The study in this essay also aims to verify, falsify or nullify two hypotheses very often referred to in the political discussions regarding the merit point system:The merit point system will replace affection and interest as main reasons for language studies in upper secondary school and cause a rectification amongst the students choices of additional courses.The merit point system will have a segregating effect upon society and make it harder for people to rise in society through education in the future.A verification of these hypotheses would imply the appearance of an increased rectification amongst students as well as an orientation towards an in the future more segregated society.The empiric material has been collected and examined with qualitative as well as quantitative methods (questionnaires and interviews) and belongs epistemologically to the phenomenological and hermeneutical traditions..

Analys av mellanspÀnningsnÀtet i centrala delar av VÀsterÄs stad
The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by MÀlarenergi ElnÀt AB and located in the city centre of VÀsterÄs, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.
Axle Link - en kortslutningsskyddad sÀker DC-överföring
Denna examensrapport redogör för hur man kan fÄ en kortslutningsskyddadoch sÀker inkoppling av en DC-lÀnk mellan tvÄ skiljda elektriska system.Rapporten bygger pÄ hur en lastbil ska kunna fÄ en större sÀkerhet för attbibehÄlla sina elektriska bromsar om tex ett av bromssystemen tappar sinordinarie matning.Lastbilens bromssystem bestÄr idag av tvÄ skiljda elektriska system med ett 24volts strömförsörjande batteri vardera. Det ingÄr tvÄ stycken elektriskabromsar i varje system. Om det tex blir fel pÄ en av bromsarna och dennapÄverkar ett av systemen vill man kunna koppla bort denna enskilda bromsmed sitt system. Man vill Àven kunna försörja den fungerande bromsen somsitter i samma system via en sÄ kallad Axle Link. Denna strömmatningslÀnksitter mellan tvÄ hjulpar pÄ samma axel.I denna studie undersöktes möjligheten att realisera en kortslutningsskyddadoch sÀker DC-överföring via en Axle Link, i första hand med diskretakomponenter.
Digitalisera loggboken : En analys av utmaningarna med att utveckla IT-stöd för kunskapsintensiva verksamheter
Failed system development projects are a common sight within the IT-industry. During the last ten years we have seen several more or less disastrous high profile projects being reported in the news. One aspect that might hold some of the responsibility for these failures is the fact that more organisations are knowledge intensive which makes their work processes difficult to capture in computer systems. How requirements engineering is handled becomes even more important in these cases, where processes are unpredictable and rely on individual judgement and knowledge. In this study we have examined the challenges of developing systems for knowledge intensive businesses through a method of qualitative case study of a university laboratory.
Livet bakom skÀrmen : En kvantitativ studie om nÀtmobbning och nÀtkrÀnkningar bland unga vuxna
Numera utgör Internet en sjÀlvklar del i svenskarnas dagliga rutiner. AnvÀndandet av sociala medier och annan digital interaktionsteknik kan föranleda negativa konsekvenser för individen. Till följd av InternetanvÀndandet har en ny arena för krÀnkningar och mobbning uppstÄtt. Tidi-gare forskning har i huvudsak studerat nÀtmobbning och nÀtkrÀnkningar bland barn och ungdo-mar varpÄ föreliggande studie studerar fenomenet bland unga vuxna. Studien syftar i huvudsak till att undersöka förekomsten av nÀtkrÀnkningar och/eller nÀtmobbning, via digital interaktions-teknik, bland unga vuxna, detta bÄde ur ett förövar- och offerperspektiv.
Bremsningens effekter hos hÀst : utvÀrderat med hjÀlp av termografi, hormonanalyser och hematologi
Twitching is frequently used in horse management because of its sedating and pain-relieving effects. In this study, the effects on the horse?s nervous system by twitching were investigated by thermography of the skin temperature. The temperature is regulated by the sympathetic nervous system through postganglionic sfincters at the capillaries of the skin. The effects on the endocrine activity have also been studied by the measuring of ACTH and cortisol in blood plasma.
Prefabricerade passivhusvÀggar
Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.
Dimensionering och konstruktion av Villa X
AbstractIn the fall of 2003 a project was started in the Swedish building sector that is called BASTA (the building sectorsâ termination of especially harmful substances). The project is operated by the building companies NCC, Skanska, PEAB and JM, the Swedish Building Industry and the Swedish Environmental Institute IVL. The purpose of the project is to create a common environmental assessment system for the entire building industry and with the help of this system phase out the use of especially harmful properties from building products.In a large sense BASTA works like this; On the BASTA web site there is a database, to which a supplier can register the company and the companyâs products. Only those products with a substance content that fulfil the demands of the BASTA system, is to be registered. As it is the supplier himself that carries out the registration of the company and the companyâs products to the system, the BASTA-organisation annually controls that the companies that are registered in the database, fulfils BASTAâs demands.Since NCC is one of the companies that operates BASTA, BASTA is probably going to be the environmental assessment system that is recommended for the company in the future.
CSCW-system ? Framtidens patientinteraktion
Tester pÄ mÀnniskor, sÄ kallade kliniska studier, Àr en viktig del i utvecklingen av nyalÀkemedel och samtidigt en stor kostnad för lÀkemedelsföretag. Framförallt nÀr patienternafinns pÄ mÄnga olika platser blir processen bÄde dyr och tidskrÀvande. Real time InteractionPatient Evaluation (RIPE) Àr ett koncept och en prototyp till ett Computer SupportedCooperative Work (CSCW) system, utvecklat av Elof DimenÀs och Mats Sundgren(AstraZeneca) i samarbete med IT-universitetet. Systemet ska stödja interaktion med patienteri effektstudier och att övervaka medicineringen och dess effekter. Tanken med RIPE Àr attman ska kunna göra effektstudier med symtomskattning med hjÀlp av mobiltelefoner ellerInternet.
Sammankoppling av fjÀrrvÀrmenÀten i Nyköping och Oxelösund : miljö- och systemkonsekvenser
District heating covers most of the residential areas and industries in the twoneighbouring Swedish municipalities Nyköping and Oxelösund. In Nyköping,Vattenfall AB VÀrme produces heat in a bio-fuelled CHP plant. In Oxelösund,waste heat and use of waste gases from the steel production at SSABOxelösund is the basis in the district heating system.This report examines the environmental consequences of a connection betweenthe two district heating systems. A broad system approach is used and the focusis on environmental effects in the system.A system analysis has been performed on the result of simulations of differentheat and electricity production alternatives. The alternatives simulated wereone where Vattenfall Nyköping covers the base load in the joint district heatingsystem and two where the power plant at SSAB Oxelösund supplies the heatbase load.The conclusion in this report is that the consequences of connecting the twodistrict heating systems can be both positive and negative, depending onsystem boundaries and on the environmental focus.
"Skyll inte pÄ friheten" : en analys av den liberala miljödiskursen i Sverige
The paper is a discourse analysis of the liberal environmental discourse in Sweden today. It is based on articles in two of the main liberal Swedish newspapers, Dagens Nyheter and Sydsvenska Dagbladet, and a liberal periodical, Neo.The purpose of this study is to analyze how the environmental problems that have been produced by the industrialised society, especially global warming, are seen upon in the liberal discourse in Sweden today. The theoretical point of departure is a discourse analysis that as a method seeks to analyze the material to reveal what assumptions the discussion departs from, and what assumptions the discussions reject.The thesis concludes that the main trends in the discussions are to position the environment against the financial system and state that the capitalist system is the only system that can solve the environmental issues. The existing environmental problems are not denied, but constantly belittled and only considered to be a problem if it poses a direct threat to humans. The solution for these environmental problems is believed to be the strengthening of the financial system and the development of new technologies..
