Batterilyft för telekom basstationer
The purpose with this thesis work was to design and build a technical aid for installingbatteries in telecom base stations. Today that job is done manually, since there is noequipment on the market for that purpose. Installing batteries in base stations manually isa very tough job.To get ideas for possible solutions a preliminary study on existing lift aids was done.From the preliminary study the conclusion that some kind of overhead crane would besuitable for the task was drawn. After that a lift for installing batteries in base stationswas designed, built and tested. The tests show that it is possible to minimize heavy liftingwhen installing batteries in telecom base stations, at a relatively low cost.ii.
Medborgare, sträck ut din arm : Bloddonation och blodhandel i Folkets Dagblad 1985-1998
The purpose of this BA-study is to analyse articles about blood selling and blood donations in the Chinese daily newspaper People?s Daily between 1985 and 1998.With publications of popular scientific material, reports from rallies and portraits of blood donating ?heroes? etc., the People?s Daily, i.e. the Chinese Communist Party, actively addresses the underlying cultural reluctance to give blood by different means. People?s Daily and the CCP resolutely aims to transform negative Confucian and other traditional notions of losing blood into representations of courage, honour, duty, etc.
En vacker död : Manlighet i fyra japanska samurajfilmer
AbstractA beautiful death ? Manliness in four Japanese samurai moviesThis thesis deals with the samurai and his portrayal in Japanese historic movies and what kind of messages he conveys in form of masculinity to theater audiences. Four movies were chosen, two from the 1960s and two from the 2010s. The reasoning behind this was to look at two eras of samurai movies and if possible try to see differences between them. The history of the samurai, being a man and woman in modern Japan, R.W Connell and famous Japanese authors from different time eras acted as tools to try to answer the questions in hand.
Utveckling av ett provtagningssystem för alkohol och aldehyder i fordonsemissioner.
A system for sampling of alcohol and aldehyde from diluted exhaust gases from vehicles powered by ethanol has been developed and tested. The major part of the work has been research of earlier work in the field and the construction of the sampling system.The part of the system constructed for the measurement of alcohol has been shown to work, however, more test should be performed. The part of the system constructed for the measurement of aldehyde was tested parallel to a commercially available system, based on the same principle of measurement, and has been shown to work well.Determination of the concentration of gaseous ethanol using a FID has shown the since earlier known fact that a FID is not able to measure a correct concentration of ethanol. Furthermore it has been shown that high concentrations of gaseous ethanol can not be kept in a bag more than a few minutes without a substantial decrease of the measured concentration..
Våga inte blunda : en studie om förskollärares syn på anmälningsplikt enligt socialtjänstlagen
The aim of this study was to capture preschool-teachers thoughts and experience basing on the obligation. Are there any policies and procedures for preschool-teachers to use when suspicion that a child is being abused occur. Are there some factors that may affect preschool-teachers to report to the social service? How does the preschool-teacher find the contact with the Social Service? I conducted four interviews with four preschool-teachers, two of these preschool teachers are employed at the same municipal preschool and the other two are employed at two other preschools. The interviews were semi-structured and were conducted at each individual?s workplace.
Finns det ett samband mellan rekryteringskvalite? och soldatkvalite?
The Swedish Armed Forces have undergone a significant change where we have gone from recruitment through duty and replaced it with a voluntary based defence. Across Europe, countries that have undergone the same type of change demonstrate change in the quality of those recruited. The focus in this paper is how recruitment quality looks in Sweden after three years of volunteer based defence and if officers at P7 can see a change in quality on those recruited. This work aims to investigate whether soldier quality has changed from conscription recruited to voluntary recruited soldiers. The question that the work tries to answer is whether one can see a change in quality in soldiers and in that case how.The result can be summarized as one begins to see a change in recruiting quality but it is not something that is visible at the regiments.
Analys av oljedimavskiljare
3nine has developed oil mist separators for the manufacturing industry. They are used in factories and workshops in Sweden as well as many other countries. The basis for this thesis is to investigate the performance of these separators in applied environments under different circumstances and to find factors that influence the performance. It has been shown both theoretically and in laboratory environments that the sizes of the particles in the oil mist influences the performance of separation. This is to be verified under applied circumstances as well.The separators also have in most cases, after the centrifugal separation, HEPA-filters mounted that separates the remaining oil mist.
Den kommunala arbetstagarens rätt till yttrandefrihet kontra lojalitetsplikten gentemot arbetsgivaren : The municipal employees freedom of speech versus the duty of loyalty towards the employer
SAMMANFATTNINGSyftet med uppsatsen har varit att beskriva och analysera gällande rätt, vad avserförhållandet mellan den kommunala arbetstagarens rättigheter till yttrandefrihet kontraden lojalitetsplikt som denne genom anställningsavtalet har gentemot sin arbetsgivare.Eftersom det finns en hel del praxis inom området främst från Justitieombudsmannen(JO), eftersom det rör sig om kommunal verksamhet, använder jag mig i uppsatsen avflera uttalanden och beslut från denna instans.Yttrandefriheten är en av de mest grundläggande rättigheterna i ett demokratisktsamhälle och är i Sverige en grundlagsfäst rättighet. Rätten att fritt kunna uttrycka sinuppfattning är viktig för att information skall kunna spridas, och att alla skall kunnavara med och påverka samhället via dialog och debatt.Teknikens utveckling och sociala mediers utbredning gör att information och åsikterblir lättillgängliga för en stor krets av mottagare.Att använda sig av sociala medier och via bloggar och facebook ge uttryck för åsikteroch attityder blir allt mer frekvent förekommande, och det är inte helt ovanligt att mansom arbetstagare kommenterar sin arbetsplats, chef eller verksamheten man är anställdinom.Arbetstagaren i den kommunala verksamheten har ett förstärkt skydd för sinyttrandefrihet gentemot arbetsgivaren (det allmänna) genom den grundlagsfästameddelarfriheten och meddelarskyddet.I uppsatsen redogör jag för de rättigheter och det skydd som den kommunalaarbetstagaren har när det gäller att utnyttja sin yttrandefrihet i form av kritiskauttalanden gentemot arbetsgivaren.Förutom rättigheten att uttrycka kritik gentemot sin arbetsgivare har den kommunalaarbetstagaren också skyldigheter att anmäla missförhållanden inom vissa områden,Detta via lex Maria och lex Sarah, vilket jag också redogör för. I uppsatsen beskriverjag även det betänkande som i april i år (2011) presenterats angående lex Sarah inomskolan.I uppsatsen konstaterar jag att rätten till yttrandefrihet går före den lojalitetsplikt som ioch med anställningsavtalets ingående uppstår.Jag konstaterar att lojalitetsplikten i kommunal verksamhet inte existerar när det gällernegativa eller kritiska yttranden gentemot arbetsgivaren.Lojalitetsplikten handlar för den kommunala arbetstagaren i själva verket enbart om hurman skall utföra sina arbetsuppgifter, inte vad arbetstagaren uttrycker om sinarbetsgivare..
Effektivisera materialflödet med hjälp av självgående truckar
The thesis that follows is performed in collaboration with Nitator in Oskarström.The factory in Oskarström focuses on laser cutting, robotic welding and surfacetreatment of steel for the automotive industry.The project aims to streamline the flow of materials in production by automatingthe movements of the forklifts, running to and from the interlayer, and betweenworkstations.The project started with a systematic literature search. The literature searchshowed the research position around the AGV-system. Also a review of studentliterature was made, so that a suitable method for practical implementation couldbe developed and applied. Selected method uses both quantitative and qualitativeapproaches, which is analyzed by using triangulation.The work has resulted in a modified layout of the current facility in Oskarströmthat can be used for the implementation of the AGV-system. It has also resulted inthe tender documents and profitability calculation from several of AGV-suppliers..
Förutsättningar och Avsättningar för Biogas för Gröna Vessigebro : Version 1.0
The community Vessigebro, in Falkenberg and its surrounding areas housing one percent of all dairy cattle and two percent of all pigs in Sweden. This means that there is a large amount of manure as a basis for producing biogas in the area. A number of farmers have therefore formed a cooperative named Vessigebro biogas and started the project Green Vessigebro, with the goal of creating the conditions for a more profitable and more sustainable agriculture production.The study deals with the conditions and sale opportunities of the feasibility study Green Vessigebro. The study has looked at the work that was previously carried out for the biogas that could be produced on the farms in Vessigebro, The main pipeline for natural gas on the Swedish west coast and its operators, the Swedish Competition Act , Electricity Act , Natural Gas Act, the District Heating Act , Sustainability Act , previously proposed measures, municipality interest in biogas from Vessigebro , possible collaborations, possible sale opportunities and perform calculations with data from the municipality Ljungby for a suggested transportation of biogas between Vessigebro and Ljungby.The study shows that there are several interesting sale opportunities for biogas from Vessigebro. The production and use of biogas in Sweden is increasing and the trend seems set to continue.
En studie av sociala faktorer : Som kan medföra problem vid implementering av informationssystem
Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.
Utveckling av sprutpump : Konstruktion och utvärdering av prototyp
This report describes how a syringe pumpwas developed for Q-linea AB inUppsala Science Park as a bachelor´sthesis at Uppsala University. Thepurpose of the syringe pump is toreplace existing pumps in one of Qlineasdosage instruments. The reasons for whythe pumps are replaced are that they arebig and heavy. Therefore the task was todesign a smaller and lighter syringepump.The goal of the project was to create aprototype of the design that met themechanical requirements posed. Therequirements were met.In the report the work process can befollowed from the development of thespecifications to the final design andtests of the prototype.
Israel, en etnisk demokrati-En studie om Israels demokratiunderskott.
The state of Israel is known as the only democracy in the Middle East. The purpose of this study was to examine if there is aspects in the Israelis society that can be questioned in terms of liberal democracy.Areas of concerns in the study are the Israeli official policy's concerning inclusion and exclusion of their citizens in areas of property owning, personal status and the duty of military service.The results show that the Israeli society distinguishes their citizens in these areas by their ethnic origin, in favour for the Jewish population. The law prohibits changes in the states Jewish character. One clear example how this is presented is that a Jew is prohibited to marry a non-Jew. The results show also that this official policy by the Israeli state violates important principles of liberal democracy.
Utveckling av OBD-II-gränssnitt för fjärrdiagnostik av fordon
This Master Thesis documents the development of an On Board Diagnosis (OBD-II) interface for remote diagnosis of vehicles. The Master Thesis is part of a project at the company Wayfinder Systems in Lund. The purpose of this thesis was to design a scantool that communicates with a vehicle through its OBD-II port using relevant standards. In order to make the OBD-II interface development easier, a car simulator was first built. Both the car simulator and the OBD-II interface were implemented using a linux computer running a C-program with serial communication with an external electrical interface.
