Identifiering av synkronmaskinsmodell genom SSFR-test

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

"Sök Er ej till Stockholm" : -Om sambandet mellan bostadsbrist och tillväxt

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

Tid- och kostnadsanalys av innerväggar

In our thesis we will compare interior walls, both bearing and non-bearing. All of thewalls analyzed are currently used in production by Skanska Construction, who is alsoour employer/supervisor for the project. The different wall types will be comparedfocusing mainly on time, cost and workability. All of these walls aside from the nonbearingwall are constructed using concrete, either prefabricated or cast on site..

Sensor för hydraulolja

This is the final documentation of the basis that can be the foundation of how to solve theproblem with leaking hydraulic oil in a shoe press at the company Albany InternationalAB in Halmstad, Sweden.The project has been performed at Halmstad University as a degree project commissionedby Albany International AB. The purpose of the degree project was to find a way ofdetecting the hydraulic leak of a shoe press. The reason is that the shoe press runsunattended during nights and weekends, this can cause an extensive decontaminationwork and production stop if leak. The hydraulic oil could be leaking in large amounts orslowly as a fine mist. The development of a working system that can detect a hydraulicoil leak and stop the machine before a large amount of hydraulic oil leaks out wouldconsiderably reduce the cost of the decontamination work.

Organisationskommunikation i praktiken En kommunikationsgranskning på Arkivator Falköping AB

The goal of this Masters thesis is to examine how people at the production department of Arkivator Falköping AB perceive the internal organisational communication transfer and exchange of information, by means of a communication audit. The objectives are also to characterise the communication climate and the respondents satisfaction with the internal organisational communication within the organisation. The results of the study are compared with the companys information policy and with previous research in organisational communication. Answers from different demographic groups within the population are compared. The communication audit was conducted using a modified and added version of a questionnaire originally compiled by the International Communications Association.

The purpose of this thesis is to examine how key performance indicators are being used as performance management tools within the production industry. Specifically the purpose is to investigate how the KPI:s within the telecommunications industry drives reusability regarding production test systems. This thesis will also highlight today?s cost models and suggest improvements of the KPI and what new ones could be introduced. A case study at Ericsson AB has been performed.

En studie om svenska börsnoterade fastighetsbolag : hur väl lämnas upplysningar om förvaltningsfastigheters värdering och varför kan detta skilja sig åt?

Property companies? results are affected by unrealized changes in value of properties. Since market values are never completely reliable there is always a risk with revaluation with property´s value. The fair value is determined only when a sale is completed. The paper studies how well the Swedish listed property companies reported under the accounting standard, IAS 40.

Kassationer på ett livsmedelslager - Effektivisering och kvalitetssäkring av processen för intern kassation i enlighet med Lean Production

Today's fierce competition means that companies constantly must develop their business and internal processes. Focus on processes and continuous improvement is something that characterizes Lean Production which ICA logistics are applying with their concept Leading Logistics. Standardized routines for handling damaged gods were insufficient at the ICA distribution center in Kungälv. Handling and registration of damaged gods were not performed uniformly, resulting in problems with controlling and monitoring the process.The purpose of this thesis was to analyze and make recommendations how the process of internal handling of damaged gods could be improved. Therefore a comprehensive understanding was needed of the entire material flow through the warehouse and important quality aspects such as product safety and delivery reliability.The methods used are literature reviews, interviews and observations to produce a comprehensive process mapping of the current situation at the distribution center.

Hur påverkar olika faktorer prissättningen på produkten Komplett Media Center a20?

Prissättningen för ett företag kan påverkas av flera olika faktorer. Dessa faktorer är antingeninterna eller externa. När ett företag ska prissätta en ny produkt är det svårt att bedöma vilkafaktorer som är väsentliga. Utgångsläget är kostnaderna för produkten och därefter tas hänsyn tillhur de externa faktorerna påverkar prissättningen. Syftet med denna undersökning är att bedömahur marknaden, interna beräkningar och valutasvängningar påverkar prissättningen på produktenKomplett Media Center a20.För att bedöma hur de olika faktorerna påverkar prissättningen på produkten har vi utfört engruppintervju med företaget Komplett Data Sverige AB.

Kartläggning och dokumentation av läsutvecklingen i förskoleklass och årskurs 1

Syftet med denna undersökning är att ta reda på hur tre förskoleklasslärare och tre lärare i årskurs 1 kartlägger och dokumenterar den tidiga läsutvecklingen. Vi vill även undersöka och analysera lärarnas syn på de material som tillämpas för att kartlägga elevers läsutveckling. En utgångspunkt i undersökningen har varit Eskilstuna kommuns remissupplaga av den språkutvecklingsplan som träder i kraft hösten 2012. I studien har vi undersökt Språkutvecklingsplanens relevans för arbetet med kartläggning och dokumentation av den tidiga läsutvecklingen. Denna kvalitativa undersökning baseras på intervjuer med lärare, rektorer och den ansvariga utgivaren av kommunens Språkutvecklingsplan.

Undersökning av processparametrar för optimering av sol-gelprocessen för produktion av kärnbränsle

A clean and affordable energy source for cooking is deficient in developing countries. People rely on fuels that contribute to environmental, social and health problems.Biogas is an alternative energy source and an increased investment in small-scale biogas production can in several developing countries be found. Several projects have started to use the technology in developing countries because of the benefits with biogas. Some cases in the establishment of biogas plants have succeeded and some have not. The study is a literature review supplemented by two field studies.

Geoenergilösning för DN-huset

In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.

Reproduktion och odling av ål

SammanfattningSyftet med den här litteraturstudien var att ta reda på vad det finns för möjligheter och svårigheter att producera ål i fångenskap. Med nya hållbara metoder att föda upp konsumtionsål skulle utfiskningen av glasålar minska i världen och man skulle kunna fortsätta äta den goda rökta ålen med gott samvete.Det finns välutvecklade metoder för att inducera könsmognad hos han- och honålar. Detta utförs genom att injicera hormoner och man kan därför fråga sig om det är hållbart i en produktion för framtiden. Efter kläckning av larverna finns flera viktiga faktorer att ta ställning till, så som utfodring och optimal hållning av ålarna. Även ägg- och mjölkekvaliteten spelar en stor roll när det gäller att hålla ålarna vid liv.Abstract The aim with this study was to find out how far we have come to develop reproduction strategies in eel culturing.

Effekter av ett informationsintensivt material- och produktionsstyrningssystem

We were assigned to do this master thesis by Husqvarna AB who at the time for this thesis just had implemented a new material and production planning system called Replenishment system. Husqvarna AB wanted us to examine the effects of their new planning system to see if it was profitable or not. Husqvarna AB had for a time considered their delivery and supplier service to bee their biggest problem and they wanted to solve this problem by improving the communication with all involved actors in the logistic chain, which they hoped would result in a better mix of products in their warehouses. The aim of this report was therefor to analyze eventual effects for Husqvarna AB when changing from a traditional material- and production planing system to a more information intensive one. The result of this report showed effects on decreasing administrational routines and improved flexibility and lead-times.
