Överföring av och beräkning med timmätta värden ? från MT2000 till Xpower

New technology makes it possible to remotely measure all consumers in a power network onan hourly basis and store the values in a database.This thesis work describes the conversion process between automatic meter reading systemMActor and calculation software Xpower.Then the possible differences between calculations of power networks using load curves incombination with a yearly estimate of consumption and calculations using hourly measuredvalues is examined.The result of the comparison shows that, for the power network under inspection, nosignificant difference could be noticed. This does not mean that calculations using hourlymeasured values would be unnecessary. I believe that in a near future calculations using hourmeasurements will be the primary choice for many power companies to whom technology isavailable.Also some basic calculations of fundamental power network parameters, such as power factorand loses, are presented using hourly measured distribution transformers in combinations withits hourly measured loads.The report is written in Swedish.

Elproduktion med ORC-teknik ombord på fartygsserien MK II.

Given that the oil prices have risen and the environmental regulations has become more stringent, the interest in operating efficiency has increased. The project has investigated the possibility of producing electricity from waste heat generated in the diesel process. One technique to utilize and convert energy into electricity is the ORC (Organic Rankine Cycle). This process is based on the Rankine process (the steam process), the difference from the traditional Rankine process is that instead of water as a working medium, an organic substance is used. The main component used in the process is a evaporator, a turbine, a condenser and a pump.

Empirisk studie av den radiella förspänningskraftens variation i klassiska skärskruvförband

In this study, the pre-tension force in an insert screw connection are examined in order to establish a greater understanding of the system and to facilitate the process of making new metal cutting tools. Certain especially significant design variables such as the offset, the length of the contact thread and the shank length above the threaded hole, are selected to be closely examined. A comparison of the influence on the pre-tension force between threaded holes made with a worn, versus new, threading tool is also involved in the experiment. The study is limited to handling the screw sizes M2,5 and M3,5. The results show that a regression model, with good approximation, can be fitted to the measured values.

Integrationsprocesser bland 6 invandrade japanska personer i Sverige

This research outlines studies about the relationship between social integration process of Japanese immigrants in Sweden and how social media assists in this process. The purpose of this research includes: To find out the reasons of migration to Sweden for six Japanese immigrants, any difficulties that they faced at the beginning of their immigration process and/or any positive qualities that they found in living in Sweden, whether they have accessed social media since they have moved in, if they do so, how the social media has been used and also, whether the social media has had a role to play in contributing to help their social integration process. In addition, it has been considered whether the participants have plans to return to Japan. In Sweden, there is relatively small Japanese migrant population. This social science research paper is the first in Sweden which explores the immigration process of Japanese migrants into Sweden.

Energianalys av Svensk Växtkrafts biogasanläggning i Västerås

Svensk Växtkraft is the owner of the biogas plant in Västerås. The company is planning to increase their treatment capacity at their biogas plant. In connection to this work it is also possible to make some energy saving changes to the biogas plant. The objective of this study was therefore to make an electricity and heat survey of the biogas plant, a detailed study of the heat consumption in the sanitation step and also a comparison of energy consumption with the present sanitation method and an alternative strategy where the waste is treated in 55 °C during 10 hours (the current method is heating to 70 °C during 1 hour). The energy survey was conducted in close collaboration with staff at the biogas plant. The current during normal operation was measured, power was calculated and multiplied by the time of usage to obtain the energy consumed.

Att göra förändring: en studie av ledarskap och organisation vid förändringsarbete

The purpose of this essay is to analyse how the leadership and the structure of the organization affect the process of changes within a specific department in Lunds kommun socialdepartment, from the director of social work to the co-workers at Utredningsenheten för ungdom och familj. We aim to answer the following questions;How does the structure of organisation affect the process of change?What do the co-workers and the leaders believe is the best way to engage the co-workers in the change?How does the leaders view their own leadership in the process of change?How does the co-workers view the leadership in the process of change?How does the leadership affect the process of change?To develop an organisation and to make it a functional, change is a necessity. The leaders are they who create the change but the co-workers are they who make it happen. In the process of change, leadership and the leaders capacity to create motivation for the co-workers, is therefore a matter that is decisive to its success.This is a study based on a qualitative method, where the interview is the main source of empirical material.

Förslag till förbättringar av materialhanteringen kring packningslinan hos Spaljisten AB

The purpose with this report is to give structure to the storage area betweenproduction and packaging at Spaljisten AB in Åseda. The purpose is also to givesuggestions for improvements of work tasks and thereby simplify and improve thematerial handling at the packing process.The background of the task is that Spaljisten AB is going to increase theirproduction and thereby they also need to increase the packing rate of theirproducts. They will manage this by installing a new automated packing line andincrease the efficiency of the old manual one. The theoretical background ismostly obtained from literature which contains relevant facts for our report.The storage area has been studied visually in order to search for improvements oftoday?s layout.

Institutet för språk och folkminnen : En arkivförteckning för teckenspråksmaterial som överlåtits av Sveriges Dövas Riksförbund

This thesis at the Institute for Language and Folklore has as its purpose to lay a foundation for a continuinginventory work. The tasks I have performed during my time there was to create an archival description, anintroduction to the material and a process map showing the process of incoming delivery of documents. The aimwas never to finish the list of work, but to structure the material to get an insight into the material and to theproblems that existed within. The documents are of a very unique nature and require that the archivist is familiarwith and have knowledge of sign language. One of the problems I encountered was how fragmented the materialwas.

Att skriva musik : magi eller teori?

The aim of this project was for me to write two complete songs and to get to know my creative process better. I wrote two songs, made musical arrangements for them, transcribed the music in Sibelius, rehearsed the material with two musicians and at last recorded it in a studio. Throughout this I kept track of my own creative process. The project resulted in two complete songs with arrangement. I learned that I have some difficulty handling adversities in my songwriting, and that it was not so easy to get to know my own creative process as I thought.

SPICA - ARISTO JÄMFÖRELSE studie av analysprogram med avseende på spånningskollaps i elektriska kraftsystem

Safe operation of a large synchronous power system as Nordel is not an easy task.There are several aspects to take into consideration. This thesis focuses on the problems due to voltage collapses in a transmission system.The ability to foresee an upcoming collapse is vital to maintain stable operation of the grid. The grid operator at Svenska Kraftnät (SvK) uses the computer program SPICA to predict the maximum transfer limit at specified transfer sections. SPICA uses actual states from the grid to predict the transfer limitation, and a quarter later a renewed estimate is produced and so on. This means that the operator can se his transfer limits vary every fifteen minutes.Our task in this project is to validate the accuracy of the limitations obtained by SPICA.

Time efficiency in a product development process

Purpose: We wish to gain a deep knowledge about product development processes in relation to the aspect of time in companies in highly technological and rapidly changing markets. The purpose is to establish how organizations better can employ time as a resource to make the product development process more efficient. Conclusions: Information we gathered from theory and primary data show that information flow, synchronization and time profit when seeing time in three dimensions are factors which should be reflected in the architecture of a product development process. To illustrate our findings, we decided to create a model..

"Att jag blev jag" : - en sociologisk analys av homosexuellas "komma ut" process

Denna uppsats handlar om homosexuellas ?komma ut? process och hur samhällets normer påverkar denna. Vi ville ta reda på om och hur en ny identitet skapas när någon kommer ut som homosexuell och hur samhällets syn på normbrytare är samt hur normbrytarna upplever det.Denna studie är gjord med hjälp av kvalitativ metod, vi har intervjuat elva öppet homosexuella män och kvinnor för att få reda på deras upplevelser och känslor kring sin ?komma ut? process.I analysen kommer vi bland annat fram till, med hjälp av tre teorier: identitet, heteronormativitet och biografiska vändpunkter att ?komma ut? processen inte behöver vara en vändpunkt i alla homosexuellas liv..

Effekter av nya PBL : En studie av processen från handläggning av bygglovsansökan till slutbesked

It has now passed two years since the new site- and construction law, PBL, went into force. It replaced the previous PBL applicable since 1987, and it involves relatively large changes in many different areas of the construction sector. The ambitions of the new law are for instance to simplify and clarify the legal text, increase efficiency in the permitting processes and improve the quality of construction. To achieve this, a variety of changes was made. Some of the most important are: inserted deadline in the processing of building applications, extended assessment of building applications, revised rules about controlplan and quality manager, a certificate is required to start and end the project, an additional meeting is inserted and the construction management of the municipalities will have to do a mandatory visit at the work scene.

Medling vid brott : En explorativ studie av medlingsprocessen på Höglandet

Mediation is a process in which various actors are involved with each other, this involvement is what the mediation are built on, because all the actors complement each other, they coordinate their work. This is not an interaction between various actors, it?s a participation. There is no research on this kind of participation, and therefore we believe that this is a scientific problem. The purpose of this paper is to implement an exploratory study of stakeholders views on the mediation process.
