Uppföljning av EcoDrivingutbildning

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey wasperformed. The voltages and currents have continuously been sampled in the incoming 10 kVsubstation HSP01 from April-August 2008. Power quality measurements were also performedin Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of theinduction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps tothe plant. The reason for the latter measurement was due to registered negative transients eachtime the motor was connected to the grid. The cause of the transients could be explained by thecoupling in the substation, the ageing of the motor which could result in damage of thebearings or resonance in the motor circuit which amplifies high frequency harmonics.

Vapenhandel : En kontradiktion till EU:s utvecklingspolitik?

Arms trade is a multi-faced issue, it can increase the state's economic revenue; however also endanger the human security. The European Union's member state United Kingdom is one of the five largest arms traders in the world. The EU promotes human security in its work, especially in the union's development policies. These circumstances address the main question of the study: is there a contradiction between the UK's arms trade and the EU development policies. The objective of this study is to research the stately weapon use in three of the UK's trading partners, and how it could affect the EU development policies.

Fisksamhället i Spexhultasjön, Nässjö

The lake Spexhultasjön is a moderate humic mesotrophic lake that is not acidified. The fish fauna was investigated by using a standard method for sampling freshwater fish with multi mesh gill nets. The fish fauna was diverse with perch, pike, tench, common whitefish, and roach. Perch and roach dominated. There were few pikes.

Ljuddesign för rumsmetaforbaserade talgränssnitt

In this paper, a navigation support approach for speech-only interaction based on auditory icons for room-based designs is presented, i.e. naturally occurring sounds that have a natural mapping to the system's underlying design metaphor. In contrast to many recent investigations that have focused on multi-modal or augmented reality systems, this paper concerns a unimodal speech and sound-only system. An auditory icon based prototype system for buildings maintenance support using a room-based metaphor was developed. The design was evaluated in a comparison with earcons and no-sound designs.

Automobike: en cykel med aktiv balans

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.

Parallell beräkning av omslutande volymer

This paper presents techniques for speeding up commonly used algorithms forbounding volume (BV) computation, such as the AABB, sphere and k-DOP. Byexploiting the possibilities of parallelismin modern processors, the result exceedsthe expected theoretical result. The methods focus on data-level-parallelism(DLP) using Intel?s SSE instructions, for operations on 4 parallel independentsingle precision floating point values, with a theoretical speed-up factor of 4 ondata throughput. Still, a speed-up between 7?9 are shown in the computation ofAABBs and k-DOPs.

En virtuell klädkollektion : En rapport om processen i att designa och illustrera en virtuell klädbutik till Stardoll.com

This is a report that goes through the design process of designing and illustrating a virtual clothing shop with the theme ?Stockholm Streetstyle? for the website ?Stardoll.com?. The purpose of the report is to examine how you can manage to get as close to designing a certain style or theme as possible, and also how the process of designing a clothing line can work, The illustrations were made in Adobe Illustrator and the final result of the project was an illustrated fashion collection with 21 parts, in the total of 6 outfits, and also a background for the shop. .

Välfärdseffekten av en konkurrensutsatt tågmarknad

The aim of this paper is to describe how to measure welfare effect of the deregulation and increased competition of the public transport by railway in Sweden. The paper also includes a numerical example of how to measure the welfare effect. In our study we use public data from SJ regaring quantity and ticket prices for the period 1996 - 2005. We have used equivalent variation, EV, as the method to measure the welfare effect. We demonstrate how to derive the equation to calculate EV by starting with a Marschallian demand function.

Att vara lärare i en mångkulturell skola

This thesis will discuss teachers handling of the background, experience and earlier acquired knowledge of students. Our aim is to study the teachers? use of the cultural knowledge that of which the students already possess and the consideration the teachers have for the students own parental tongue. From this we want to see if there are any obstacles or pits with the work of gathering up experiences. The study is based on interviews with seven different teachers at a multi cultural elementary school in one the suburbs of Stockholm.

  Förnamnstrender 2007 jämfört med 1998 : En personnamnsstudie

Denna uppsats handlar om vad som hänt i namnskicket bland personnamnen mellan år 1998 och år 2007. Syftet är att se vad som har hänt, och varför, på nio år. De 100 vanligaste pojk- och flicknamnen 1998 och 2007 har undersökts och tendenser har framkommit. De korta namnen, de namn som tillhör de nordiska, de namn som var populära kring år 1900 och de lite mer ovanliga namnen har blivit mer populära 2007 jämfört med 1998. Namn med betydelse har blivit mer populära bland flicknamnen, medan bibliska namn blivit mindre populära bland pojknamnen.

Value creation form a gender perspective - a case study of Caran

Women ledaers and profitability, is there a correlation? Earlier research show different outcome on the correlation between women leaders and profitability. A Swedish consultant firm, Caran has a belief that more women leaders would create more financial profit, we ask us if that is the true situation. Using two different IC measurement methods we have shown the difficulties in calculate intagible resources, which methods that can/ can not be used and if women leders create financial value. We found the women leaders in Caran to add more value per dollar spent on the woman leaders than the value added per dollar spent on men leaders.

Lycka: nyckeln till en önskvärd socialpolitik - en begreppsanalys

This essay deals with the same task that utilitarians have tried to solve for a long time, what is happiness? In the eighteenth-century utilitarians suggested that happiness should be the base for social political decisions. But the lack of definition disposed so that GDP became the measurement of happiness, which proved to be wrong when the unhappiness continued to increase. More than two hundred years later scientists came up with a new definition of happiness and new ways to measure it. And during the last decade economists have taken the discussion to a higher level.So once again we?re dealing with the same old issue, if happiness ought to be the base of social political decisions.

Effektmätning i pump

The interest for power and energy measurement has greatly raised with todays increasing electricity prices and enviromental awareness. In the search for energy efficient solutions, the measurements are more complex due to increasing of non linear components. Harmonics and non sinusoidal voltages put high demands on sampling and filtering. Meanwhile, the price must be controlled so the customer still will find it interesting to invest in smaller plants. ITT W&WW asks for a robust, heat resistant power meter with compact dimensions to allow mounting inside the casing of a pump.
