Igensättning av övre spalten i centrifugalpump

This report focuses on the upper slit. The upper slit is located between the impeller andthe drive unit. The slit design depends on pump type and application. However it isuncertain why the design varies, The purpose of this report is to clarify why the designvaries and to recommend an improved slit design.A research has been done; information was gathered from interviews, but also fromsearching of databases and studies of drawings, reports and documents. The originalpurpose of the slit was to prevent twining around the driveshaft, and prevent dirt fromentering the cooling system.

"Jag är bättre än så" : En studie om hur stimatisering- och stämplingsprocesser kan påverka föredetta kriminella mäns anpassningsmöjligheter i samhället.

ABSTRACTThe aim of this study is to look into how ex-offenders experience that stigmatization and labeling- processes might affect their possibilities to create an integrated and adapted life in society. It is also of interest to study how and if the interviewees experience their self-image to be affected by these processes. Our research-questions are:-          How do ex-offender males experience stigmatization and labeling-processes to impact their possibilities when trying to re-integrate into society?-          Do ex-offender males experience their self-image being affected by stigmatization and labeling-processes? If so, how are they affected? In order to achieve this we interviewed members of the organization KRIS in Örebro, where we selected males over 23 years of age with a prior prison sentence. The study is based on the labeling-theory of Howard Becker as well as the stigma-theory by Erving Goffman.In the conclusions derived from the results we found that the interviewees experience a more distinct and obvious stigmatization and labeling from authorities such as the police and the legal system, than that from other people in society.

????Att lösa reglertekniska problem med Modelica

Modelica is a multi-domain and equation-based modeling language. Modelica is based on object-oriented principles and non-causal modeling. The language is constructed to facilitate reuse and decompose models. The models and the modellibrary can modified to design a new nonlinear components.Object-oriented modeling is an excellent way to analyze and study large complex heterogeneous physical systems. The object-oriented modeling approach build on reusing and decomposition of models and non-causal modeling.Modeling physical systems often leads to a DAE system with index 2 or 3.

Informell motivation och dess betydelse : En studie inom tillverkningsindustrin

Many times it can be the simple things that affect the attitude of work and which have an importance on the organization's effectiveness. These are not always apparent but can have a large importance for the motivation and the attitude of work. Large number of companies uses wage and other financial rewards system but is there any form of informal factors that have an importance for the coworkers and that affects motivation. What factors that affect the motivation within the industry are interesting to examine and specifically the factors that are not apparent, in other words informal factors that increases the motivation. The purpose of this thesis is to examine and describe which informal motivator factors co-workers/employees in a production department think are meaningful.

Den teoretiska utmaningen - En undersökning om nyinstitutionalismens (o)förmåga att förklara förändring.

This thesis aims to examine the possibility of understanding social change by using new institutionalism approaches on a specific case, The case, which describes the implementation of new public management reform in the Swedish health care system, is analysed from two separate new institutionalismperspectives; the tool perspective and the symbol perspective. These approaches differ from one another in the sense that the first relies on a rational choice ontology, while the latter rather refers to a sociological tradition. In the analysis, causal explanations as well as aim related explanations are presented. Formative moments such as economic stagnation, non-socialist governments and ideological isomorfism are presented as important factors behind the reformation. By using the tool perspective, the motives of the idea spreading and reformation of the Swedish health care system, are connected to a strictly rationalbasis such as cost efficiency and quality improvements.

När viljan att ha är större än rätten att få. En studie av fusket inom socialförsäkringen.

Abstract För att vi i fortsättningen skall kunna ha ett allmänt försäkringssystem med legitimitet, krävs det att tron på systemet är så pass stark att det inte finns en känsla av att det går att fuska sig till förmåner. Det handlar inte i första hand om att minska statens utgifter genom att reducera fel och fusk. Huvudmålet är snarare att minska felen och fusket för att upprätthålla rättsordningen och framförallt legitimiteten i systemet. Om inte denna legitimitet finns får vi ett bräckligt system som när som helst kan haverera. Syftet med uppsatsen är att analysera själva fenomenet bidragsfusk med hjälp av ekonomisk teori och göra en teoretisk analys av varför fusk förekommer.

Change Lab : Att arbeta med lärande förändring

In order to be able to change, to maintain competitiveness as a company in a world where rapid changes is part of the daily life, it is crucial to have knowledge and methods in how to change. One method, originally developed in Finland, is the Change Laboratory. This method is said to be efficient, not only concerning change aspects but also learning, since change and learning in this method is intertwined. This Master Thesis (20p.) tells about the process of conducting a Change Laboratory with a Swedish high-tech company and analyses factors in the process that makes change possible..

Anskaffning av standardsystem : en företagsstudie

Vid affärssystembyten väljs ibland standardsystem framför egenutvecklade system. En orsak är att egenutvecklade system är dyra och komplicerade att bygga. Flera företag tycker också att det är smidigare att implementera standardsystem då dessa är utformade som en paketlösning där samtliga moduler är integrerade.Ett problem för företag är att välja "rätt" standardsystem. Ett arbetsmål i denna uppsats är att ta reda på i hur stor utsträckning företag använder sig av en metod i anskaffningsprocessen. Huvudfokus är att ta reda på vad företag tycker är viktigast att anpassa - verksamhet eller system? Ett annat delmål är att titta på hur företagskulturen förändras vid ett standardsysteminförande.I undersökningen görs sex företagsintervjuer hos företag som alla har anskaffat standardsystem.

Studiemotivation en jämförelse mellan gymnasieelevers egen uppfattning om motivationsnivå och Self-Determination Theory : en jämförelse mellan gymnasieelevers egen uppfattning om motivationsnivå och Self-Determination Theory

Studien handlar om svenska gymnasieelevers motivation för att studera matematikämnet. Den teoretiska grunden hämtas ifrån Self-Determination Theory (Deci & Ryan, 1985). Studiens syfte är att undersöka hur väl gymnasieelevers egen uppfattning om sin motivationsnivå kan prediceras genom de fyra ingående motivationsorienteringarna i Self-Determination Theory: (1) external regulation; (2) introjected regulation; (3) identified regulation; och (4) intrinsic motivation. Deltagarna (n = 132), 44 pojkar, 84 flickor och fyra som valde att inte specificera kön, studerar vid två gymnasieskolor i Falu kommun. Deltagarna fick via en webbsida besvara en enkät som mätte variablerna: upplevd motivationsnivå, external regulation, introjected regulation, identified regulation och intrinsic motivation.

Maktstrukturer i svenskt näringsliv: En social nätverkstudie av delade styrelseledamöter i Sverige 1985 och 2005

This paper examines the interpersonal and intercorporate networks of interlocking boardmembers among Sweden's 50 largest publicly traded companies in 1985 and 2005. We find that both the interpersonal and intercorporate networks of 1985 are considerably more coherent and densely connected than those of 2005. The observed changes in social network structure are compared to changes in company ownership in Swedish publicly traded companies during the same period, and it is found that the observed changes in network density and cohesion can be related to a notable increase in the number of foreign board members. These results imply that the social organization of the Swedish system of corporate governance has changed notably during the period. Social network theory suggests that these changes can explain the greater demand for external regulation, decreased homogeneity of board members and increase in board member compensation observed under the period.

Semestereffekter på Stockholmsbörsen

Syftet med denna uppsats är att ytreda huruvida det existerar en semestereffekt på den svenska aktiemarknaden.

En simuleringsmiljö för distribuerad navigering

This master thesis studies distributed navigation which isa function implemented in a future network based combat information system to improve the accuracy in navigation for combat vehicles in a mechanized battalion, above all in the event of loss of GPS. In the event of loss of the GPS the vehicles obtain dead reckoning performance through the backup system that consists of an odometer and a magnetic compass. Dead reckoning means a drift in the position that makes the accuracy in the navigation worse. The distributed navigation function uses position and navigation data with measurements between the vehicles to estimate the errors and uncertainties in positions, which are used to improve the accuracy in position for the vehicles. To investigate and demonstrate distributed navigation, a simulation environment has been produced in Matlab.
