Emhart Glass AB är världsledande företag inom glasflasktillverkning. Dekonstruerar automatiserade maskiner som formar glasflaskor. I Sverige finns dettvå fabriker, en i Örebro och en i Sundsvall. I Örebro tillverkar man främstreservdelar och nya delar till maskinerna medan man i Sundsvall monterar ihopmaskinerna. Det finns totalt 15 olika fabriker och kontor över världen medhuvudkontor i schweiziska Cham.Eftersom Emhart Glass Örebro har för långa ställtider på några av deras maskinerska det undersökas hur omställningsarbetet går till i dagsläget och huromställningsarbetet skiljer sig åt mellan operatörerna.

Borrning och gängning av laxkilar till vågkraftverk med industrirobot

To make wave power more competitive on the market Uppsala University leads projects that examine how to accomplish better efficiency in the production. One of these projects is described in this report and examines whether it is possible to make the production of dovetails more efficient by using an industry robot of type ABB IRB6000 S3 M91. This project is using an already presented working method, from a previous project, which involves that the robot picks up the dovetail and moves against fixed cutting machines where the dovetail will be drilled, threaded and milled. Drilling and threading are the sub operations that will be examined in this project where experiments are made with the presented working method and with equipment from Uppsala University.Experiments show whether it is possible to drill the holes in the dovetail within specifications by using the specific robot and the presented working method. The threading operation is examined theoretically if it is possible to accomplish by using the same working method.

Tid i all oändlighet och förgänglighet. En studie av tidsanvändningen i Sverige sedan 1980-talet

This master thesis in economics discusses the time use of today as well as the observed trends in time use over the last 20 years in Sweden. This is done by analysing time-use and consumption data at the microeconomic level, i.e. by explaining individual behaviour given the economic assumption of a rational behaviour. We reach the conclusion that the value of time is an important explanatory variable concerning the rationality in that time is used differently by different individuals and in the changed use of time. Furthermore, other variables such as social norms and the process benefit of a certain activity, i.e.

Karakterisering av bioslam för modellering av biogasproduktion

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Passiv face time - En studie av passiv face time på ett företag med flexibla arbetsförhållanden

The purpose of this study is to examine how employees in an organization using flexible work practices, experience that passive face time influences the evaluated of them. Further, the study aims to understand to what extent that perception of passive face time motivates the employees to spend more time at the office than is necessary for their work situations. The study concludes that employees in general perceive that passive face time does influence how they are evaluated and that this perception motivates employees that are relatively newly employed by the company to spend more time at office..

Negotiating Work-Life Balance: Working Time Preferences and the European Working Time Directive

This thesis examines why working time preferences differ between workers and nations, and explains the effect of working time regulation and working time flexibility on negotiating work-life balance. In five separate sections the following working time issues are examined: the number of hours worked by workers in Europe; factors affecting individual working time preferences; how working time preferences are negotiated in the national industrial relations systems of Sweden, France and the United Kingdom; how the institutions of the European Union have influenced working time negotiations through the Working Time Directive; and the benefits and practices available to organisations implementing working time flexibility. Broadly this paper views working time preferences as being a highly personal and influenced by factors such as wages, taxation, culture (national and workplace) and non-work responsibilities. It is argued that negotiating a preferred working time pattern is essential to achieving work-life balance and when such a balance is achieved, workers are more healthy, motivated and committed to their employer. Essentially this provides an incentive for businesses to voluntarily implement working time flexibility beyond the regulatory standards..

Mjukvaruplattform för riggstyrning

Today the competition in the automobile industry is getting all tougher. The technology behind cars becomes more advanced. To get ahead of competitors car companies has to look into new areas of innovation.One important area is vehicle safety. Bigger companies have come so far in vehicle safety that difference between cars more depends on the car type (size) than the technology behind it.There is one area where vehicle safety that still has great opportunities for improvement, which is in active safety. The term active safety states that the car has the ability to identify treats and automatically respond to the treats.

Höghöjdsanpassning av BvS10 : Konceptstudie för optimering av överladdningssystem

This report relate a concept study that consider a number of different proposals to improve the overcharging system in BAE Systems Ha?gglunds tracked vehicle series BvS10, to maintain sealevel power at extreme altitude.At high altitude the power losses beacuase of the air density that decreases, which results in less fuel can be burned. The decreasing of air density also gives rise to fatigue failure of the turbocharger unless power is reduced.The proposals shall be as required by BAE Systems Ha?gglunds economically sustainable and defensible from a packing perspective. That means the selected solution must have a reasonable price tag and at the same time a minimal impact on adjacent components.The basis for this thesis is based on benchmarking of both the auto industry as the flight industry, to find inspiration and tips for improvement.Some of the concepts have after gathering facts and calculations been excluded while other solutions has been considered as workable and thus interesting for BAE Systems Ha?gglunds.Initially the current turbochargingsystem was analyzed in order to determine the starting point and thus be able to fix the current problems surrounding high altitude driving.

 This report is about the principle and his / her role at the school it?s also about how the principle understands the role, its expectations and the demands connected. The facts are based on deep detailed interviews with three different principles. The theoretical approach is coming from ?hermeneutiken? and ?Gadamers? ideas regarding how an individual is creating the world and the surroundings to act within.

Competition for forest fuels in Sweden : exploring the possibilities of modeling forest fuel markets in a regional partial equilibrium framework

This thesis project focuses on the need for better tools for analyzing competition for forest fuels in Sweden, in particular how policy measures may influence the market and involved actors in different regions of Sweden. Raw materials from the forest have for long constituted important inputs in the Swedish forest industry. Today some of these raw materials are increasingly used as inputs also in bioenergy production, largely driven by bioenergy promoting policies, and there are signs of increased competition for forest fuels which may have various and uncertain effects on the industries in question. The thesis project explores the possibilities to adapt previously used forest sector equilibrium models into a new model suitable for analysis of Swedish forest fuel markets, called the Swedish Forest Sector Trade Model (SFSTM). The approach takes into account regional differences in supply and demand for 23 types of products produced and/or used by eight types of producers, plus consumers, in five different regions (four Swedish and one international).
