Noggrannhet vid målinmätning : Analys av ett eldledningsinstrument med förbättringsförslag
This Master Thesis has been conducted as an assignment of the Swedish Defence MaterialAdministration and the Swedish Armed Forces and aims to examine the Target Location Error(TLE) of a Forward Observer System. The targeting accuracy of the system is vital if the systemis to be used as a sensor for precision munitions. The analyzed system, EOI (FOI 2000), wasdelivered to the Swedish Armed Forces in 2007. The targeting sequence starts with deciding theposition of the system with a GPS-receiver, continues with methods where the north direction issettled and ends by measuring the distance, direction and elevation to the target. When allparameters have been measured the system calculates the position of the target.
Utvärdering av jetomrörning : En studie gällande utvärdering av omrörningssystem vid Ekeby reningsverk
Biogas is a renewable energy produced through anaerobic digestion, which means that organic matter is degraded by microorganisms under anaerobic conditions. The produced biogas can then be used for cogeneration, electricity, heat or upgraded to vehicle gas. Eskilstuna Energy & Environment AB has four digesters at Ekeby water sewage treatment plant, Eskilstuna. One of the biogas reactor (RK4) is equipped with a jet-mixing system while the remaining digester uses top-mixing. The mixing system is an important parameter to achieve optimum operating conditions for the process regarding gas production and degree of digestion.
Tydligt men komplicerat : om upplevelser av ledningssystem
De flesta företag använder sig av något slags system för att kontrollera arbetsflödet. Dessa system används av alla på företaget och därmed är det viktigt att undersöka, hur medarbetarna upplever detta system. Med en explorativ utgångspunkt gjordes en enkätstudie på ett företag i Västsverige. Resultatet visade att deltagarna, förutom några få procent i stort sett hade liknande positiva upplevelser. Ingen skillnad fanns heller mellan grupperingarna ung/gammal eller antal år de arbetat på företaget.
Digitalt utbildningshjälpmedel : Interaktiv karta för utvärdering av militära övningar
Precis som titeln avslöjar handlar rapporten om att utveckla ett system som kananvändas vid utvärdering av övningsmoment. Idag saknas ett liknande system somvara ett stöd för hemvärnets instruktörer vid utvärderingar som har till syfte att ökaförståelsen hos övande personal. Systemet består av en mobilapplikation och enwebbapplikation. Mobilapplikationen loggar hur en soldat har framryckt under ettövningsmoment och sedan sammanställs data från en eller flera mobilapplikationer ien webbapplikation där data visas på en interaktiv karta. Kartan ger möjlighet attstega sig igenom händelseförloppet.
Tredimensionell sensorscanner
This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..
Webbsystem för matprisjämförelser
This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.
Det Intelligenta Huset : - En studie i hemautomation
Today all buildings contain some form of home automation. It might be heating controlled by athermostat or motion detectors controlling outdoor lighting.This paper,The Intelligent House, deals with the planning of a house in Kiruna, in the north ofSweden and further immerses itself in home automation or intelligent control in single-familyhomes. The house has been entirely planned, from layout to structural design and plumbing.The purpose of the paper has been to investigate the possibilities in home automation in singlefamilyhomes and to choose a suitable home automation system for the house being planned.The system has been designed and the costs and energy savings have been calculated.The system chosen for the house is called KNX and is the largest system for home automation inSweden. It is used to control heating, ventilation, lighting and alarm systems in the house. Is hasbeen found that KNX is very expensive and that the amount of energy, possible to save in thehouse, using the system, is relatively small.
Från det livskraftiga lantbruket till det olönsamma : en studie av skäl till minskad verksamhetsomfattning och varför man bor kvar
This essay is a study that contributes to the larger research question ?Why do farms shut down?? The subject was chosen because it is a relevant problem that needs to be studied more. This study's boundary is to investigate the reasons for decisions leading to the farms at the Torstuna community, Fjärdhundra, changes in any activity scale or the outlook of the entire farm. When a decision is made, there are usually several reasons behind it and it is these reasons which this essay is aiming to study. The question "What are the reasons for the elderly to live on the farm even though the farm is not cultivated by them?" is also covered in the study.
