Analys av energilagringssystem portfolio för Volvo hybrid konstruktionsmaskiner

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Bolivia kvinnorörelser och multietnisk stat

This thesis examines the possibility of Bolivian indigenous women?s social movements? getting their demands of a gender equal society fulfilled in the new state which was initiated in 2005 when Evo Morales became the first president representing the indigenous people of the country. By using a qualitative method I have showed that although the Bolivian indigenous women?s social movements? historically has been significant political actors for social change in the country, with representation at both regional and national level, Bolivian women are still subordinated in the social and political sphere. By applying a feminist intersectional perspective which takes its point of departure in a understanding of power as multidimensional, where gender, ethnicity and class are constitutive principals, multiculturalism theories and a social movements theory framework, I have found that even if institutional changes, that opened the system increased the indigenous women?s social movements political participation in Bolivia, power structures based on gender limited their possibilities to influence both socially and politically.

Tidssynkroniserade mätningar i vattenkraftstationer

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.

Ett folkstyre i förvittring eller fortsatt demokratisk livskraft? En studie av de norska och danska maktutredningarnas slutrapporter

AbstractThis paper is a comparative study of the final reports of the Norwegian and Danish power studies performed in 2003. While the Danish study found that democracy is thriving, the conclusion of the Norwegian power study was that democracy is in a crisis. The purpose of this paper is to find explanations to why the studies in two Nordic countries arrived at such different results.Methodologically, the paper consists of an ideological text analysis and critical analyses of the discourse. In order to study how the results of the power studies can differ so considerably, the following aspects have been surveyed; 1) external contexts (government inquiries); 2) work process (the researchers? background, role and co-operation); 3) the problem areas and themes studied; and 4) power perspectives.

Styrning mot förändring: En fallstudie rörande organisatorisk förändring i offentlig sektor

This paper examines and analyzes effects of the introduction of a new management control system tool within a Swedish public health organization, the Södra Älvsborg hospital, and its possible effect on organizational change. The new management control system tool, known as the SÄS-model, has been widely criticized for being too costly and with too small positive effects to be shown. Our approach has with that as a background been to examine whether the implementation of the SÄS-model and its balanced scorecard has been able to result in effects regarding organizational change. We have through a case study aimed to analyze how a management control system, much alike one that is typically used within foremost private organizations, can promote organizational change. Our results suggest that the implementation of the SÄS-model and the balanced scorecard has given the organization clearer visions and goals.

Gå in och ut och vända "ut och in" : En kvalitativ studie om hur omsorgspersonal inom hemtjänsten arbetar för att de äldre ska få ett värdigt liv

The aim of this study was to increase the knowledge about if and how the National Value System?s goal of a life with dignity for the elderly pervades the work in home care organisations. The study was based on a qualitative research method and was conducted through interviews with professional care givers in home care organisations, there were five individual interviews and one pair interview. The background for this study was the National Value System for the eldercare that was introduced in 2011. The theory of New Public Management and the concept of Rationality of Caring were used to analyse the result.

Content Management Systems : effektiviserar informationshanteringen?

För ett par år sedan tog utvecklingen och fokuseringen kring Internet fart på allvar ute bland företag. Alla skulle ha en webbsida och anledningen till detta var ofta att konkurrenten hade en eller att man bara ville synas. Idag finns det ett antal så kallade Content Management System utvecklade för att hantera information på Internet, intranet och extranet. Det gemensamma för dessa system är att användarna skall kunna uppdatera, vidareutveckla och administrera lösningen utan någon teknisk kompetens. Syftet med den här uppsatsen var att undersöka om ett Content Management System effektiviserar uppdateringen av information, med hjälp av kategorier inom användbarhet.

Virtuell modulbaserad Fotbollsarena

Denna uppsats syftar att undersöka samt ta fram en modell över ett system i PC Spelet Power Soccer där användaren själv kan designa sin egen hemmaarena med hjälp av ett webbgränssnitt. Arbetet inleds med en begränsad enkätundersökning där användare fick bedöma betydelsegraden av olika inslag i en fotbollsarena. Efter resultatet av denna enkät togs en modell fram i Autodesk Maya med ett modulbaserat system. Detta kompletteras med ett webbgränssnitt där användaren väljer vilka delar som han vill placera på de olika platser som erbjuds. Till sist beskrivs själva modulen och hur den ska fungera..

ISO 9001 : En fallstudie om hur de ständiga förbättringarna, som är införda i företagets verksamhetssystem, är anpassade efter medarbetarna

MPC is the company Exova Metech?s operating system that contains all the information needed for the company's objectives and guidelines to permeate the company. How changes in the MPC should be communicated with the company's employees can be seen as problematic. Routines that have been changed in practice, the process owners do not always update in the MPC, it leads to that the employees can not ensure that duties are performed properly. It is therefore important that management takes its responsibility by providing updated information.

Kraftkabelförläggning i mark : - en studie av produktionsmetoder

The assignment given to us by NCC was to compose a degree project based on ground excavations for power cables. The aim of the study was to examine suitable excavation methods depending on different possible terrain conditions. The amount of previously written material within this subject is nearly non- existent and therefore there is a genuine interest by the NCC to receive a compilation of different production methods. The greater part of this study is based upon interviews with several companies active within this area of expertise. The technique of placing the electricity grid beneath ground for safety is today getting more and more common.
