Optimering av antenndesign utifrån experimentella data

During the work at Gateway Security AB in Motala I began examining available antenna models to get a wider perspective, this have given knowledge of their structure, and an understanding of their function. All my necessary fact is based on my observations and notes of these measurings. New antenna models, and available models were examined where measurements at different heights and different distances on the antenna were performed with the help of an oscilloscope and a measure probe, peak ? to - peak was brought on the signal. The measurements are presented in a line diagram.

Religion i fängelse : En studie om möjligheterna kring religiöst utövande i anstalt

In this study, religiosity in prison is investigated. What opportunities are there for those detained to practice their religion and how did their religiosity change after they were detained? Six interviews were conducted to gain a better perspective of religiosity in prison. The focus is on Correctional Institution in Kalmar, where surveys have been conducted over a longer period but also the monastery at the Correctional facility in Kumla is discussed. Most interviews were conducted in the prison of Kalmar, in a room where religious conversations are conducted.

Barn- och ungdomshockey utifrån ett tränarperspektiv : En kvalitativ studie om tränarnas uppfattningar om barn- och ungdomshockey

Abstract________________________________________________________________Författare/Author Richard TähtinenTitel/Title Youth hockey from a coach perspective. A qualitative study about coaches´appreciations concerning youth hockeyThe aim with this study is to strengthen the knowledge about coaches´ appreciationsconcerning youth hockey. This study contains interviews with three leaders that operate onthe strategic level within youth hockey and three coaches working with youth players in theages of 11 and 12. I have divided my main results into 4 categories, based on an earlier studyfrom Karin Redelius (2002). These categories include the following themes:1) Competition on the good and the bad2) The importance of winning3) Shake-out versus sports on children’s terms4) Instruction, play and learningThe main conclusions in this study show that leaders on the strategic level appreciate youthhockey in a very similar way.

Nesligt våld mot kvinna : En undersökning kring synen på kvinnor som blivit våldtagna i Karlstad perioden år 1900-1943

The purpose of this paper is to examine the early 1900s approach to women who have been raped in Karlstad and how you looked at rape during this period. I have used criminal case files from the Karlstad criminal police to examine. The actual study is set up in that way that I have tried to answer my questions through case studies that have been categorized in three type?s perpetrators and three types of victims. The three types of offenders who I am using are the "the naughty young man," "the violent worker" and "the drunken man".

Proxyserver för passiv informationssökning

In today?s society the average person is flooded by information from everywhere. This is in particular the case when using the Internet; consider for a moment the fact that a decent search engine at this moment scans 8 058 million homepages. For a user that repeatedly comes back to the same site, the case is often that they know what they are looking for. The problem is to isolate the important information from all the other information embedding it.We would like to state that we have found one possible solution to this problem, where the user himself can define what information he is looking for at a specific server, then scan the server when visiting it with his browser.

Optisk sortering av matavfall : en jämförelse med en minskning av svinnet

The purpose of this study is to compare the energy related and environmental consequences of implementing optical sorting as a means of waste collection with those of reducing food waste. In addition to studying the possibility of implementing optical sorting in downtown Stockholm, the yielded amounts of energy from waste collection and reduced wastage will be calculated. This is done by way of literature reviews and interviews. The amount of energy that can be generated through optical sorting and biogas production via anaerobic digestion in downtown Stockholm is 29-44 TJ/year, compared to 118 TJ/year saved by completely eliminating food waste. The generated biogas can replace fossil fuels, but the required food waste contributes to increased greenhouse gas emissions as well as reduced bio diversity and eutrophication during the wasted food?s lifecycle.

Bestämning av metanpotential hos blåmusslor och nötgödsel

Kraftig övergödning i Östersjön leder till ökad blomning av alger som medförsyrebrist i havet. Musselodling kan ses som en åtgärd för problemet. På den svenskaöstkusten beräknas skördningen av musslor vara på ca 65 000 ton/år.Rötningsförsöket av blåmusslorna skedde i en pilotanläggning på Linnéuniversitetsom består utav en lakbädd och en UASB-reaktor (Upflow Anaerobic SludgeBlanket), där syrabildningen sker i lakbädden och metanbildningen i UASB.Musslorna gav ett metanutbyte på 0,32 m3/(kg VS) för hela rötningsperioden.Ensy AB specialiserar sig på att producera koncentrerad växtnäring från gödsel. Dehar som planer att utveckla sin verksamhet för att samköra produktion av biogas frångödsel. Gödslet som erhölls från Ensy AB rötades i ett satsvist försök i nio behållaremed 100g/behållare.

Dokumentation av ensilering med fokus på clostridiesporer i mjölk :

To produce milk of good standard the feed for the animals kept for milk production is an important part in the work of quality. This makes it important to feed them with good forage, especially when feeding with silage. The process of making silage is very complex and requires a careful handling to be successful. The fundamental idea is to create an anaerobic environment in the herbage to favour the desirable micro-organisms, in this case the lactic acid bacteria. This environment is created by careful handlings were the importance is to pack the crop well and cover it as soon as possible to exclude oxygen.

Kloning av möjlig promotorsekvens uppströms kloritdismutas i Ideonella dechloratans.

Perchlorate and chlorate are naturally occurring in the atmosphere, from here it sediments into groundwater and soil. The pollution is increased by discharges of perchlorate and chlorate from agriculture and paper mills. Bacteria capable of reducing perchlorate and chlorate to chloride and oxygen can be used to get rid of these contaminants. However an anaerobic environment needs to be sustained in order for this reaction to be used. For this reduction to work in an aerobic environment as well, a greater knowledge of the reducing enzymes, regulating factors and their corresponding genes is needed.

Vem vinner: fackboken eller den skönlitterära boken? : en studie över lånevanor i en 3:e klass i en mindre by i norra Sverige

The purpose of this thesis is to investigate the habits of borrowing books among third-grade pupils. My aim is also to study what significance their teacher and the librarian have on the pupils? borrowing habits. Based on the results from an experiment, two observations, interviews and by compiling a list of short summaries of literature relevant to my thesis. I wanted to compare earlier research with my own results and also reflect on remarks made by librarians and teachers concerning the children?s reading and use of the library.

Utveckling av biopsiinstrument : Instrumenthållare för skruvnålsbiopsi

This Master Thesis has been carried out in cooperation with Ursus Medical AB (URSUS) which markets, assembles and sells the Rotex Screw Needle Biopsy Instrument ®. The instrument is delivered with an instrument holder. Customers had expressed dissatisfaction over that they needed to use two hands during a biopsy procedure, which resulted in a project to develop a new instrument holder.The project aim was to create concepts for how the new instrument holder should be designed, with focus on the mechanics. The new instrument holder would build on the existing basic principle that the screw needle and the cannula were screwed into the tissue. The thesis work would result in a technical solution and a functional prototype of the chosen concept.To achieve this, a generic product development processes were used and began with a comprehensive literature review.

Utdragshållfasthet av inlimmade skruvar i limträ

In this thesis tests has been performed on the pull strength of screws glued into glulam beams.The experiment is based on the already approved method whereby the diameter of the drilled holes is the same as the screw outer diameter of 1 mm or bigger. The screws strength class shall not be less than 4.6 (EN ISO 898-1:1999, 1999).The difference in the experiments that were performed where that the drilled diameter were 1 mm smaller than the outer diameter of the screw so that the screw thread was worked into the wood.In the tests the gluing where made on M8 glulam beams. The screws where drilled at and angel of 90°tangental to the fiber direction with a diameter of 7 mm. The gluing of the screws where made in three different depths and where later exposed to pulling forces. The results showed both pulling breaks and screw breaks when they reached their maximum capacity.

Laborativt arbete i grundskolans naturorienterande ämnesområde : En problematiserande analys om grundskolans relationer till omvärlden, utifrån tre identifierade områden, med biogas som ett praktiskt exempel.

I detta arbete används biogasprocessen som ett exempel på hur ett samhällsrelaterat vetenskapligt område kan lyftas in i skolans naturvetenskapliga undervisning. Vi har arbetat fram en laboration om biogas och givit förslag på hur en sådan kan användas direkt i skolan naturvetenskapliga laborativa delar. Vi föreslår ett sätt att prova om elevers nyfikenhet och upptäckarglädje för naturvetenskap och teknik ökar om undervisningens innehåll och upplägg är aktuellt och samhällsrelaterat. I arbetet har vi kommit i kontakt med tre områden: Ett naturvetenskapligt forskarsamhälle, tillämpningar i samhället av ett naturvetenskapligt innehåll samt skolans naturvetenskapliga undervisning. Relationerna mellan dessa delar är med och formar skolans innehåll och läraryrkets komplexa uppdrag.
