?Det var en tyst kamp? : En ekokritisk analys om utvandring och fo?ra?nderliga system i Vilhelm Mobergs Utvandrarna

The purpose of this essay is to do an ecocritical reading of Vilhelm Moberg?s The Emi-grants from 1949. By asking and answering the three following questions; How does a system present itself, What are the different reasons for emigration; Why does differentsystem fit some well and some not.By using two articles from Green Planets - Ecology and Science Fiction to illus-trate two different views; Different parts value in an ekosystem and The Ship as an ecosystem. I have also created, based on the literary text four different terms concern-ing the dynamic system; Stable, Static, Unstable and Collapsing systems. I have found that all system goes through changes, some drastic, that changes the way the parts of the systems fit with in it.

Energieffektivisering av Åhlénshuset i Umeå : Utredning av åtgärder för ventilation, värme och kyla

Sweden is a country that has made some progress in developing energy efficient solutions. The problem in Sweden is that many houses and apartment buildings are old and have inefficient ventilation- and heating systems. This energy is lost when systems are inefficient, which then results in huge economic costs. Luckily, more and more people are becoming aware of this, which means that Sweden is on track to become even better within energy efficiency.Energy use for the housing- and service sector amounts to 166 TWh of total use at 616 TWh. Without distribution and conversion losses, these figures show that the housing- and service sector accounts for almost 40 % of the country's total energy consumption.

Uttorkning av Betong

This Thesis aims to explore how to integrate an IT-system for facilitating anorganizations work with Continous Impprovements.This is done here by examining and analyzing the process within a handful ofcompanies who seem to have been successful with their own implementations. Thestudy is focused on the implementation of one particular system, "System C2".Simliarities and differences between the companies, and the established rule of thumbfor these kind of activities are focused upon. This to emphasis how another actormight emulate some of the apparent success.Part of the core question is found in the title, since Continous Improvement is oftenseen as a relativly low-risk activity, is it then also possible to take a low-risk slow pathto the implementation of such a system in the entire organization?.

Det självförsörjande passivhuset

The housing sector uses 40 % of the energy in Sweden and half of the electricity usage. Theuse of energy is the main reason to the increasing rate of carbon dioxide in the atmosphere.This is the main motive but also a wish of higher safety, that is a higher rate of selfsufficientenergy production in Sweden, we want to decrease the need of using fossil fuel. Now whenthe energy price rise, the interest in energy issues increase and more people discuss thepossibility of reducing the usage of fossil fuel. A change to renewable energy such as sun,wind and water is the only solution where we can get a sustainable development.One way to contribute to a better use of energy is to build in the principle of passive house.The house is being built with a thick and tight insulation. If you use a heat-exchanger withhigh degree of efficiency and a final heating battery on the Ventilation system, the heat fromlamps, devices and the ones living in the house should be enough to fulfil the criteria ofliving.

Utredning av behovsstyrd ventilation : En jämförelse mellan CAV och VAV

Denna rapport är ett examensarbete på C-nivå som görs i sammarbete med teknikkonsulten Ramböll. Det vanligaste sättet att ventilera en byggnad idag är med så kallad CAV-ventilation (Constant Air Volume). Denna metod bygger på att ett luftflöde bestäms för rummet och upprätthålls med konstant flöde. En annan metod är så kallad VAV (Variable Air Volume) som bygger på att flödet varierar efter behovet. Anledningen till varför man väljer VAV istället för CAV är att med CAV finns det ofta en stor risk att man överventilerar ett rum eller byggnad, just på grund av att flödet är konstant. Problemet med VAV är att det är en högre investeringskostnad än för CAV så metoden lämpar sig bara där energibesparingen är så stor så den täcker mellanskillnaden i pris.

En studie om artikelhantering i material- och produktionsstyrningssystem på System Andersson AB

This thesis aims to develop a control system for measuring electromagnetic compability (EMC). This has meant that a controller designed around an ATmega8 microcontroller has been manufactured and programmed. It has also meant the development of a comprehensive control software in the program MATLAB. The control system has been tested with satisfactory results and can now, monitor and control measurements of the EMC-type..

Samverkan arkitektur och installationer : Osynligt ventilationssystem i utställningssal på Plan 4, Nationalmuseum

Detta examensarbete har utförts i samarbete Statens Fastighetsverk. I dagsläget pågår renoveringen av Nationalmuseum där byggnaden skall återställas till sitt ursprung och ett nytt ventilationssystem skall tillgodose ett stabilt inneklimat för bevarandet av museiföremålen. Examensarbetet undersöker hur de krav som ställs på ventilationssystemet kan kombineras med de begränsningar som byggnadens kulturminnesmärkning medför genom att besvara frågan ?Hur kombinerar man dagens behov av installationer med en kulturhistorisk byggnad utan att påverka det kulturhistoriska värdet?? För att exemplifiera denna problematik presenterar vi ett principiellt lösningsförslag för installationssamordningen till en utvald del av byggnaden.Ventilationsförsörjningen till utställningssalarna på Plan 4 utgör ett av de svåraste samordningsområdena i byggnaden. Det valda utrymmet för lösningsförslaget är bjälklaget på Plan 6 som skall försörja en av dessa salar.

Kvalitet-i-Bruk för Beslutstödssystem inom Thoraxkirurgi

The aims of the practical work carried out for this thesis were to redesign a clinical decision support system for thoracic surgeons, called AssistMe, and to evaluate the concept behind this system. The main objective of the thesis is to give an account of the considerations that were found to be of key importance for designing a clinical decision support system for thoracic surgery. Another aim was to let future users test the system after it had been redesigned and evaluate the concept behind it. The thesis also investigates users? experience of the system and their views on whether it would be applicable in their daily work practice.

Klassifikationssystem på webben: Traditionella och nya

The aim of this thesis is to investigate the opportunities of classification of web pages. Two classification systems are compared; a library classification system traditional and a system that is developed for use on the web new. UDC is chosen to represent the traditional systems, and Yahoo! represents a so called new system. UDC is used by NISS Directory of networked resources, which is a directory that uses the system for organisation of electronic resources. Both systems are analysed from two different perspectives, a multidisciplinary and a timeperspective.

Från ord till (e-)handling : - Integration av e-handelssystemi SiteVision

The client, Senselogic, had noticed an increased demand for an e-commerce system integrated into its product, SiteVision, something that did not previously exist. Senselogic wanted to integrate a third-party system to manage e-commerce. The problem was that there were very many e-commerce solutions to choose from. In order to select the best system it was necessary to evaluate the e-commerce systems and compare them to each other. To identify the elements that has to be included in an e-commerce system a study of literature was conducted.

Utveckling av internordersystem för SharePoint

SharePoint is a web based platform designed to provide internal communications and file sharing for businesses and organizations.In this project, we created a system consisting of multiple applications to be used together with SharePoint. These applications are meant to simplify the workflow for internal orders of products. The system is targeted towards companies that do not have a flexible approach to digital orders or companies that want to integrate this functionality into their SharePoint platform. The project includes, in addition to the creation of the system, installation of the software and the servers needed to run a SharePoint environment and their configurations.The system consists of four applications where one of these, the store application, is required for the system to be used at all. The other applications are an order management application, a purchase application and an incoming delivery application. Of these four, we have implemented the store application and the order management application. Our hope is that users will find the system easy to use and graphically appealing..

Vad krävs av en ERP-leverantör för att i framtiden tillfredställa mindre företag?

Ett ERP-system syftar till att ta hand om företagets resurser och skapa ett enhetligt integrerat system för dessa. ERP-system kan också användas för informationsutbyte mellan företaget, kunden och leverantörens system. Behov av ERP-system finns inom de flesta branscher oavsett storlek och inriktning men kritik har riktats mot att systemen inte lever upp till användarnas förväntningar eller tillfredställer användarens behov. Arbetets fokus ligger koncentrerat på hur mindre företags uppfattning om ERP-system är och vad som krävs av en ERP-leverantör för att i framtiden tillfredställa mindre företag. En surveyundersökning har använts för att få fram relevant information för att lösa min problemprecisering.

Utformning & placering av vädringskanaler i ett passivhus, drivet av naturliga krafter

A passive house in Norra Djurgårdsstaden drawn by Tengbom Arkitekter is going to be built. A shaft for airing is needed for a few apartments in the house.The airing shaft is designed for a few two room apartments in the house, which are not able to achieve satisfactory airing, as their outer walls are facing a single direction. The other apartments on the same floor are corner apartments. These apartments do not have the same difficulty with airing since they have their outer walls in different directions, with different pressures at the facades. The airflow in the airing shaft is supposed to be driven only by natural forces, by the sun. The purpose of natural driven forces is to achieve low energy consumption for the house.In this thesis, a design of the shaft for airing has been developed.Initially an open shaft for all apartments was analyzed.

Projekthanteringssystem

This document is a summary of my work to create a project management system for a small firm working with computer graphics. The intention is to manage customers, projects, images and invoices in the easiest possible way. To make the system as flexible as possible a web-interface was chosen which makes it possible to access the system from any computer, making it independent of any particular operating system. The only requirement on the user environment is that the computer must have a connection to the Internet to be able to access the system. The different techniques that have been used to develop the project management system is primarily Ruby on Rails and a MySQL database.

Systemförvaltningsmodeller ? verklighetsbeskrivning eller idealiserad bild?

This study will shed light on the subject of system management and system management models. It is important that everyone within an administrative organization understand business objectives and needs of the users who work with the systems. It is vital for the activity to form a structured approach for its management, which includes a system management model. Every company has its individual system management model that is tailored to support their management of a business IT systems. According to Brandt (2000), a system management system model is defined as "an idealized image of how you want the system management work is conducted".
