Decemberkompromiss eller Januariförlovning? : - en komparativ studie av svensk och finsk avtals- och arbetsmarknadsstruktur, reglering kring kollektivavtal samt reglering kring stridsåtgärder och sympatiåtgärder.
Declining union memberships are a fact in both Sweden and Finland. At the same time, the autonomous labour market parties and the high membership rates are the most significant factors for the two countries compared to Europe and the rest of the world. These two factors have in turn been developed and strengthened since the beginning of the twentieth century. By autonomous labour market parties I refer to the fact that the labour market parties themselves through collective bargaining are agreeing on the labour market conditions, without interference from the government.This paper is therefore taking it's stance in the question of what happens with the autonomous labour market parties when the membership rates are in decline. With this in mind, this paper describes the judicial development, the collective agreement and labour market structures, the legal consequences of collective agreements and the opportunities of industrial and sympathy action in both Sweden and Finland. The two countries' systems of labour law have caught some negative attention, hence two of the most discussed cases of recent years are given some attention as well. The collective judicial conditions are very similar in both Sweden and Finland regarding the labour market main actors' collaboration, the collective agreement structures and legal consequences and the opportunities of industrial and sympathy action.
Navigering, sensorfusion och styrning för autonom markfarkost
The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.
Assistansrobot "Slangaren"
This project is a step towards automatic firefighting. The goal is to decrease the number of personal injuries by replacing the human firefighter with robots or similar technical tools. Especially in very hostile environments due to risk of explosions or building collapse. A robot is easy to replace and can be maneuvered from a safe distance. The idea of the project comes from the company Drones Networking which aims for developing a totally autonomous firefighting system.
Konstruktion av tvåhjulig balanserande robot
This report discusses the development of an autonomous system that can travel a distance of atleast 30 meters on two wheels. The system, the robot, detects black lines and stops if one isdetected. A remote control can be used to start and stop the robot. The robot is constructed ofmainly steel with smaller, more detailed, parts in plastic. A significant amout of time has beenused to enable the robot to balance on its own.
Likvärdighet, i vilket syfte för vem och när? : En idéanalys av likvärdigheten i utbildningssystemet från grundskola till gymnasiet utifrån frihetsbegreppet
In which purpose, for who and when does equality get fullfilled in the education system? This studie takes aim on the upper level and second upper level school system to study what the curriculum says on the one hand and what the system brings out on the other. With critical theory as method, with Herbert Tingsten as founder, this studie analyzes the logic of the education system to set out if the pupils choice of education, after the upper level lower secondary school, in second upper level is legit with democratic principles such as freedom (of choice). The theory, used to analyze the individuals progress to be autonomous, uses Adam Swifts definition of freedom as an individual being autonomous. The findings of the study shows that what politicians chases as equality really i´snt equality.
Metoder och design av visionärt personbilskoncept
I projektet, som är ett examensarbete från programmet högskoleingenjör i teknisk design vid Luleå tekniska universitet, har ett koncept på en delvis förarlös bil tagits fram. Arbetet har utförts mot instutitionen för arbetsvetenskap och har givit värdefull erfarenheter inför fortsatta studier vid Umeå Institute of Design. Resultatet är en lyxig fyradörrars kupé med tänkt lansering omkring år 2020. Bilen sköter till största delen av tiden körningen på egen hand men tillåter även manuell körning på ett nytt och revolutionerande sätt. Fordonet är även en social mötesplats där passagerarna får uppleva en ny dimension av att resa med bil..
Knästabilitet hos ungdomar aktiva inom fotboll och handboll : En rörelseanalys som riskindikator för främre korsbandsskador
Bakgrund: Främre korsbandsskador (ACL-skador) är allvarliga och vanligt förkommande inom idrott, speciellt hos ungdomar i åldrarna 14-19 år. En förhöjd risk för ACL-skador har påvisats för individer aktiva inom fotboll och handboll, vilka är mycket populära sporter världen över. Inom dessa sporter har även kvinnor påvisats ha två till åtta gånger högre risk att drabbas än män.Syfte: Syftet var att undersöka om det fanns någon skillnad i knästabilitet vid en hopp-landningsrörelse mellan tjejer och killar i åldrarna 16-19 år, aktiva inom fotboll och handboll samt att undersöka om det fanns någon skillnad mellan fotbollsspelarna och handbollsspelarna, oavsett kön.Metod: Ett drop jump-test utfördes av 20 ungdomar, aktiva inom fotboll och handboll, medelålder ±SD 17,0 ± 0,9 år. Testerna filmades i frontal- och sagittalplanet och analyserades sedan med hjälp av Landning Error Scoring System (LESS). Post hoc-analyser genomfördes för att kontrollera skillnader i 1) graden av valgusställning i knäleden mellan tjejerna och killarna och 2) graden av knäflexion mellan fotbolls- och handbollsspelarna i landningsmomentet.
Positionsindikering i bilder och video för WITAS dialogsystem
Denna rapport beskriver arbetet med en utökning av ett dialogsystem till en UAV (Unmanned Aerial Vehicle, obemannad flygande farkost). Arbetet är utfört i WITAS-projektet (Wallenberg laboratory for research on Information Technology and Autonomous Systems), ett projekt som har som mål att utveckla en helikopter som ska kunna verka autonomt i t.ex. en trafikmiljö. Syftet med dialogsystemet är att en operatör med talspråk ska kunna ge kommandon till och få information från helikoptern. Detta examensarbete har som mål att utöka dialogen till att bli multimodal, dvs.
Quadrotor UAV : Konstruktion och användbarhetsstudie av en UAV i sensornätverk
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.
Studie av dagvattenkanalen utmed Sjöstadsparterren i Hammarby Sjöstad
In Europe, the central governments are the ones to coordinate the international standards and strategies regarding GPP; Green Public Procurement. However in Spain a GPP program was introduced late and only applied to the Central Government Institutions, (AGEA) (BOE nr. 027, 2008). These means that smaller administrations, such as, Autonomous Regions, Municipalities and Town Councils were not included in the program. The absence of a national program which excludes those governments made them introduce their own criteria for GPP, and the difference in criteria varies from one government to the other.

Att optimera för målgruppen : Processen att skapa en målgruppsanpassad landningssida för Rebtel
Företaget Rebtel ville ha en ny landningssida som riktade sig till internationella studenter. Denna sida skulle vara optimerad för målgruppen både gällande design och innehåll. En förundersökningen bestående av bland annat intervjuer med målgruppen, målgruppsanalyser och research gjordes därför. Förundersökningen bestod också av intervjuer med olika roller på företaget Rebtel för att få en inblick i olika arbetsrollers perspektiv och uppgifter under en sådan process. Med hjälp av förundersökningens fynd togs skisser fram och en landningssida utvecklades bland annat genom programmeringsspråken HTML5, CSS3, LESS, JavaScript, .NET och C#.
"Vi bara frågar dem... Är det fritids nu? ... och då sa de ja!" : En studie om barns perspektiv på gränsen mellan förskoleklass och fritidshem
The purpose of this bachelor thesis is to examine the views of the elderly and the caregivers that appear in brochures for the elderly and the discourses that can be found within. The data that the study is based on was collected and analysed using content analysis and Faircloughs (1992) critical discourse analysis. The theoretical frameworks that have been used are social constructionism, critical discourse analysis, assortment and protest, and New Public Management. The results showed two images of older people (I) the elderly as active and autonomous and (II) the elderly as passive and in need of help. The results also showed two pictures of the caregiver (III) the caregiver and NPM, and (IV), the non-profit care provider as a complement.
Modellering av manövercylindern för Nosstället på JAS39 Gripen
When models are used to describe physical phenomenon during development or modification of a technical system, it is often possible to reduce both the time needed and the overall development cost. With the use of models it is also possible to investigate the potential of the selected solution, without the need for any expensive details and testrigs. In many cases it is also not possible to test all the aspects regarding the functionality that are desired from the system, without using the complete and final product.In this case a model based approach has been used to optimize the different parameters in the new snubbing mechanism for the Nose Landing Gear Retract Actuator on the JAS39 Gripen.During the simulations, upper and lower boundaries were calculated for the length of the spring and the diameter for the restrictor. The governing constraints were given by the requirements for the retraction time during cold conditions and that the amplitude of the alternating loads in the uplock mechanism were brought to an acceptable level.The most promising results from the simulations were then used in a limited number of trials in the hydraulic rig to verify that the configurations comply with the requirements.The final parameters for the snubbing mechanism were chosen to 35±1mm for the spring and 0.4-0.5 mm diameter for the restrictor..
