Collected knowledge is then used, together with the results from the literature study, to decide energy measures to proceed with.

We live in a stressful world and a demanding society where the ability to quickly adapt is one of the most important and most difficult challenges of today. A fairly new phenomenon called intranets has evolved to meet this challenge, however many examples of corporative intranets are stories about failures and systems with poor usability. This study focuses on how the user oriented approach to systems design affected upon a system development process of an Intranet, solely developed within a company, and how it impacts on the intranets popularity among the employees in the company. The study starts not from the literature but from a survey, which is based upon the Delphi method. Which results were used for further in-depth research about the subject, by interviewing three representatives from the company.

AbstractIt is unclear how L2 students acquire vocabulary ? how is it taught ? or wheather it can even be taught. In an SSL (Swedish as second language) program for young adults the ambition has been to integrate the L2 students? into the national high school (gymnasium) courses as quickly as possible, in order to meet the students? demands for subject education and to challenge them on an appropriate knowledge level. Teachers noticed quite early that the course ? integrated L2 students seemed to have a deeper understanding of words and an easier flow in their speech.

Syftet med denna studie är att undersöka hur mycket läraren respektive eleverna använder målspråket i ämnet spanska, steg 1 på gymnasiet, samt undersöka om och i så fall hur lärarens målspråksanvändning påverkar eleverna på en nybörjarnivå i språket. Studien har utförts på två gymnasieskolor med hjälp av observationer och intervjuer av de observerade lärarna samt av elever ur varje klass. Resultaten visar att lärarna använde en väldigt liten del av sin taltid på målspråket, endast 6 %. Eleverna däremot talade mer av sin taltid på målspråket, 54 %. Men det språk som talades på målspråket var ingalunda fritt producerat, utan eleverna använde endast målspråket till att besvara lärarens faktabaserade frågor eller vid styrda kommunikativa övningar.

This bachelor thesis is based on the current discourse within the aid policy, whichhighlights and focuses on measurability and reporting of results within the development cooperation.The purpose of this study is to investigate how the Swedish CSOs Diakonia and Plan Sverige, bothoperating many of its activities through which Sida are directing Swedish aid, are influenced by theresults agenda in it?s work, and to investigate which impact this has on participation of the recipient.The research is based on information collected through examination of relevant text such asdocuments from the organisations, agencies and from debate articles and inquires. Together with datacollected through informant interviews with informants from the organizations this information hasbeen analyzed through a qualitative content analysis. The study show that the demands occurringwithin the development cooperation mainly generates quantitative, short term results in order tomaintain legitimacy as an organization. The focus has changed from a traditionally high reliance onthe organizations activities to instead focus on which results the organizations can present as a resultof its work.

Vattenfall and Svenska Kraftnät perform start-up tests, where hydropower generators are used to power up the electrical grid in case of a blackout. To monitor the electrical grid, Phasor Measurement Units (PMU) are used. Each PMU is individually equipped with a GPS-receiver to precisely timestamp the data relative to the official time UTC. During the test, it is also of interest to timestamp the measurement signals from individual hydropower generators to later compare with PMU-data, and thus study the power grids impact on the generator. The aim is to work out an appropriate method to make these measurements and to build a data acquisition system, capable of timestamp data relative to UTC, from a generator in one of Vattenfalls hydroelectric power stations. The problem is that the generator is located in an underground station which hampers the reception of GPS-signals and wiring should be avoided if possible. Time synchronization has been solved by using Vattenfalls network, which is synchronized by the network protocol NTP.

This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.

Protecting the environment has with time grown to take a more central role in the society. Agriculture plays an important role in the society since this sector produces our food. More thorough research on how agriculture affects the environment is therefore motivated. This research can be used to improve the agricultural practice from an environmental point of view. This is something that both the farmers and the consumers can profit from. This study aims to form the basis for creating environmental indicators for use of nitrogen and energy on dairy farms. Twenty-three farmers in western Sweden have been interviewed about their farms, both organic and conventional. They produce milk with different intensity, defined as the amount of milk delivered (sold) per hectare of arable land.

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

The aim of this master?s thesis is to examine how managers in some public libraries are using performance measurements and to what extent decision making is based on the results. The main questions posed are:??What performance measurements and indicators are used in the libraries examined???What is the attitude towards performance measurements among library managers???How and to what extent are performance measurements and indicators used in the process of decision making???What improvement would library managers wish regarding the development of performance measurements in public libraries?The theory is based on a model of evaluation of the public sector in addition to general steps of evaluation of quality and performance measurement results. The investigation is based on qualitative interviews with seven managers of public libraries in Sweden.

The purpose of our study is to find out how teachers can help their students to learn how to managestage fright. By interviewing high school teachers and high school students and also observe one oftheir classes, we wanted to find out how they think about the causes of stage fright and what youcan do to relieve it. We also wanted to find out how teachers are working to teach students how todeal with stage fright, and how they think that you also could work. As a teacher of music, among other things, the task is to assess and rate the students performancesin music. Several components are based on the students' courage to play on his or her instrument infront of other people.

Denna rapport tar upp för och nackdelar med att göra en webbaserad mobilapplikationgentemot en plattformsspecifik applikation för ett tidrapporteringssystem. Tre prototyperutvecklades för det existerande tidrapporteringssystemet XLTime hos Nlight Solutions.Prototyperna gjordes mot Android, Iphone och webbläsaren för dessa två plattformar.Efter att prototyperna iterativt gått igenom olika funktioner från en givenkravspecifikation går rapporten sedan in på att utvärdera hur funktionaliteten skiljer sigmellan de webbaserade och de plattformsspecifika applikationerna. Här kunde man se attswipe-funktionalitet betedde sig konstigt för vissa webbläsare, och att implementationenav input-element av datumtyp skiljer sig i webbläsaren. Felsökning och uppdatering avapplikationer var dock mycket snabbare för den webbaserade prototypen.Efter att funktionaliteten utvärderats startades användartest med 6 olika användare. Defick utföra ett antal uppgifter på varje prototyp och här kunde man se att olika problemuppstod.

In today's changing society, companies need to work with continuous change and improvement to evolve with the market. It is therefore important for managers to learn how to manage teams because they are expected to streamline selected products or processes in the business. Employees and teams need to develop in line with the changing environment in this process feedback is a tool and an important pillar. Leaders must learn to manage and transform feedback into something useful.The purpose of this study was to create an understanding of how systems-based feedback in the form of employee surveys can be a support for the leader in team development. We wanted to identify relevant behaviors and actions of the leader that may increase the work with feedback.

The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.
