This is an essay concerning the differences between boys? and girls? way of learning and how this difference influences the teaching in the technology subject. The method is divided in two. The first part is based on a survey over literature about teaching girls and boys in the technology subject. The second part is based on interviews with three male teachers in the same subject.

Actor-observer bias är tendensen där människan som aktörer tillskriver sitt beteende till yttre omständigheter medan observatörer tenderar till att tillskriva aktörens beteende till personliga faktorer. Syftet med denna studie var att få en klarare bild av hur människor i sin roll som aktör eller observatör attribuerar ett riskabelt bilkörningsbeteende. Deltagarna bestod av 101 svenska studenter från en högskola i Mellansverige varav 77 stycken var kvinnor och 24 stycken var män. Deltagarna fick svara på en enkät angående actor-observer bias och riskfullt bilkörningsbeteende. Resultaten visade att andras beteende förklaras mer av personliga egenskaper än då personen själv kör riskfullt medan yttre omständigheter inte gav skillnad för vare sig andra eller en själv.

Skiascopy, also called retinoscopy, is a method for determining the refractive power of the eye. There are only a few, old studies made on equine refraction. The aim of this study was to investigate the refractive power in a population of Swedish horses. The study consists of a review of relevant studies done on animals and an experimental part where the refractive power of 93 horses of different age, breed and usage was examined. A pilot study of 12 horses was performed regarding the importance of cycloplegia when doing skiascopy on horses. The results of the pilot study show no significant difference in the skiascopy results between the group before and after cycloplegia were induced. Consequently, there is no need of inducing cycloplegia before doing skiascopy in adult horses. The study shows that horses usually were emmetropic (normally sighted) with minor deviations toward myopia or hyperopia.

This master's thesis examines the possibilities of correction and change in a classification scheme, with regard to the changes that occur in the world the classification system intends to describe.Applying a comparative method and classification theory, the classification of the example of the former Yugoslavia (1918-1941, 1945-1991), its republics and successor states, and the languages, formerly known as Serbo-Croatian are examined through a comparison of the main classes and divisions of language, geography, and history, in Dewey Decimal Classification (DDC), and Klassifikationssystem för svenska bibliotek [Classification for Swedish Libraries] (SAB). Eight editions of DDC, from 1876 to 2014, are compared to seven editions of SAB, from 1921 to 2013. The editions have been selected in order to show the changes prior to, and following, the First World War, changes after the Second World War, and changes following the collapse of Yugoslavia in 1991.The examination shows that both systems have updated their editions according to the changes in former Yugoslavia over the years. DDC has well constructed facet schedules, especially Table 2 concerning geography, but fails, in some cases, to construct a logic and hierarchical structure for the republics and languages of Yugoslavia, partly due to the fixed classes and divisions that survive from the very first edition of DDC from 1876, but also as a result of the decimal notation, and its limitations, itself.SAB seeks to construct a hierarchically logic and equal scheme for the languages, areas, and states of the former Yugoslavia. Although the facets for geography and chronology aren't as developed as the ones in DDC, the overall result is that of a logically consistent and hierarchically clear classification, with short notation codes, thanks to the alphabetic mixed notation, which allows more subdivisions than the numerals and the pure notation of DDC.This study is a two years master's thesis in Archive, Library and Museum studies..

BARA BOSTÄDERPlacerat mellan Bollmora flerbostadshus och den gamla landsvägen breder Tyresö gymnasium ut sig. Vår ingång blir att riva skolan, materialet ?kremeras? till tegelkross och sprids i en röd löparbana längs den befintliga landsvägen, att tillåtas glömma för att senare minnas. Gymnasiet förstås som en del av det befintliga landskapet, det ändrar bara form och byter plats.Vad händer när man släcker ett lager i AutoCad?Det närvarar i sin frånvaro.

2013 a decision was made that all projects at the Swedish Transport Administration shoulduse BIM (Building Information Modeling) to some extent from 2015. BIM is an approachthat allows for streamlining of projects by the use of a 3D-model created in an early stage ofthe project. The 3D-model can carry information about the facility throughout its life cyclefrom planning to management. The use of a 3D-model can help the project to detect errors inearly stages of the project when it is easy and cheap to fix the error instead of finding theerror in the construction phase when it is costly and time consuming to fix it. 3D-models alsolead to improved communication both within the project groups and with the public.

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

This diploma work covers an investigation over the heat - and hot water systems of thetenant-owner's association, Bogården. The heat - and hot water needs of Bogården aresatisfied by both district heating as well as three heat pumps. Implemented investigationshows that the heat pumps are not used in a profitable way. Apart from that, the reservepossibilities are small. There is also a risk of the growth of Legionella bacterium in thehot water system.Since the heat pumps are already installed, HSB-Gävleborg (responsible for Bogården)has a wish to investigate possible proposed actions for optimization of existing plant.After completed investigation, a new proposed action is presented.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Jag har i mitt kandidatarbete arbetat med ljud och akustik i gamla kyrkor. Gamla byggnader och hus har alltid fascinerat mig. Det finns en sorts tyst berättelse i äldre byggnader. Jag känner en vördnad inför gamla hus och de som ritat och byggt dem. De berättar om sin tid och om saker vi glömmer bort.

Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER). An improvement is only seen when the BER becomes much lower than what is common in real situations. In conclusion DDCE is complicated, involves many mathematical operations and gives insignificant improvement of SNR when BER takes common values. It is legitimate to question if it is possible to use the method in a real mobile phone system..

This thesis is focusing on how global and local search engines retrieve information from the local domain. The three search engines tested are the global search engines Yahoo, Ask.com and the local search engine Web Wombat. The questions we examined were: which search engine has the best retrieval effectiveness? Could there be other reasons than retrieval effectiveness, to choosing a local search engine?For our test we constructed 20 questions related to Australia.We chose to divide the questions into topics like nature, sports and culture. For all questions we evaluated the relevance of the first 20 hits.

Master thesis work at ITN (Department of Science and Technology) in the areas of A/D-construction and RF-circuit design. Major goal of project were to research suitable possibilities for implementations of direct conversion in transceivers operating in the 160MHz band, theoretic study followed by development of components in the construction environment Cadence. Suitable A/D- converter and other important parts were selected at the end of the theoretic study. Subsampling technique was applied to make A/D sample requirements more realistic to achieve. Besides lowering requirements on A/D-converter it allows a more simple construction, which saves more components than subsampling adds.

In time with HolmenSkog district Egenskog Norrköping´s decreasing mountain of cleaning, the office started to look around for new alternative cleaning strategies to lower the costs connected with cleaning. One option was to make the inventory strategy more effective and after a phonecall with the head of the district, Jonnie Friberg, the planning started to try inventory in pictures taken from a helicopter. The pictures was at last taken from a digtal camera and the vegetationheight was mesured with a laser. The gear was supplied from Kallax Flyg AB, Luleå. In the trial 15 stands was selected depended on age and different mixtures between pine (Pinus sylvestris), spruce (Picea abies) and birch (Betula pubescense and Betula pendula).

In today?s society, safety in a workplace is an important factor to any organization. Focus on improving the working conditions by making them safer through technology is taking us into a time where we rely on technology to keep us safe. How well developed the technology may be, it is still not enough to keep us entirely from harm. Human error will always be a factor in the human interaction with a workplace.
