Syftet med denna studie är att få en inblick i hur lärare på mellanstadiet arbetar med teknikämnet i skolan. Detta görs genom en enkät, vars frågor är upplagda efter tre frågeställningar: Vilka tankar har lärarna om teknik? Hur ser pedagogernas teknikundervisning ut? Vilket undervisningsmaterial använder lärarna sig av i teknikämnet? Totalt är det 65 lärare som arbetar eller har arbetat med teknik på mellanstadiet som deltagit i studien. Enkäten har visat på att de flesta lärarna som deltagit tycker att teknikämnet är ett roligt, spännande och intressant ämne som dock är svår bedömt, tids- och materialkrävande. Undersökningen visar även att de flesta lärarna tycker det är bäst att arbeta med teori och praktik varvat, då båda delarna behövs för att eleverna skall förstå teknikens innebörd i samhället.

Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.

This master thesis work was done at Saab Underwater Systems AB, a company at the cutting edge of underwater technology. Here torpedoes and other underwater vehicles are developed and manufactured. The major customers are navies of different countries, mostly the Swedish navy. The aim of this master thesis is to develop, construct and evaluate an automatic Trim System for Unmanned Underwater Vehicles. The task of the system is to change the position of the centre of mass and the vehicle?s total mass or volume.

This essay seeks to analyze the consequences of modern information and communication technology for collective action within the framework of social movements. With references to the protests in Seattle 1999, the essay argues that the emergence of distributed collective action is closely related to the use of technology, for example cell phones and Internet. This distributed collective action can be characterized by its decentralized and self-organizing features, forming a global pattern emerging from local interactions. Whereas contemporary theories of collective action can be ´stretched´ to fit these aspects, they lack analytical tools to describe and analyze such systems. Further, their rejection of classical crowd theory is problematic, since it contains valuable insights.

AbstractTitle: Wireless Fidelity ? A Scenario Analysis Authors: Mellberg Ola, Technology Management, Lund UniversityMårtensson Jens, Technology Management, Lund University Tutors: Andersson Jens A, Faculty of Engineering LTHKarlberg Johan, Sony Ericsson Mobile Communication ABSvensson Claes, Lund University Discussion: The most significant impacts on the telecom industry over the past decades have been the rapid growth of the Internet and mobile telephone services. Currently these two worlds are converging. Moreover, the fast expansion of wireless high capacity Internet access, increased distribution of local/public hotspots and rapid development of wireless network cards have opened new opportunities for the mobile telecom industry. Research Questions:To what extent could the explosion of local and public wireless networks, using WiFi technology, affect the future telecom industry? Who will ultimately master the WiFi innovation and to what degree could this innovation open new possibilities for external players to enter the mobile voice industry? Purpose: The purpose of the Master Thesis is to provide Sony Ericsson Mobile Communication AB with the most transformational scenarios, which will enable employees to recognise patterns and interpret the meaning of WiFi-related events as they unfold.

This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.

This thesis investigates if a system for small scale electricity production located in anurban environment can be profitable. The work has been divided up into two parts,one extensive literature study and one case study. The purpose of the literature studywas to investigate the area, resulting in a choice of which technology to be studied indepth in a case study.In the case study a system containing small scale wind turbines and photovoltaicsmounted on Gränby Centrums roof was examined. From data containing wind power,wind direction and total irradiation, possible production from a system weresimulated. Three products of each technology were examined in the simulations.From the simulated production an economic analysis was carried out, this toinvestigate if a system is profitable.

In this Bachelor Thesis (20 p.), we present the history and development of "Intelligent Houses", and most important- explore some of the future possibilities in this area. The project has been carried out through an interdisciplinary cooperation between three different educations at the Blekinge Institute of Technology. By conducting a dialogue with various actors with different professions, we have been trying to identify needs within the concept of "Intelligent Houses", were the end user is not only the tenant or homeowner. Through Participatory Design methods, such as a Future Workshop, we have brought the users together to discuss their own and each others needs and hindrances in their respective work practice, and how intelligent house technology could improve their work conditions. We have also been testing a highly sophisticated CO/CO2/Moisture/Temperature/Enthalpy multi-sensor & controller, originally developed for regulating indoor climate systems. Based on the needs we have found in our fieldwork, we have been looking at possibilities to make multi user solutions with the sensor..

As artificial intelligence (AI) has gained more influence in recruitment, both recruitment processes and the role of the recruiter are changing. This study aims to describe and analyze how recruiters translate, use, and relate to AI in their work. Through a qualitative method based on semi-structured interviews and document analysis, the study explores recruiters? experiences, attitudes, as well as perceived obstacles and opportunities regarding the use of AI in recruitment. With a theoretical foundation in translation theory, fashion, and imitation, the study examines how AI is not only followed as a trend, but also shaped and adapted locally through translation, depending on organizational identity and needs.

Development of services that?s provided through mobile application technology in today's modern IT society has become a full-fledged market where numerous players trying to make themselves heard in everything from innovative new services to the further development of existing services. In these services actors wants to find new areas of use by taking advantage of the mobile technology.We have investigated how value is created and how the value is captured in the services provided through mobile applications. Through this, we wanted to identify the critical success factors in how a newly developed service should be designed to create value. This has been done through a thorough literature review, together with an indepth evaluation of existing applications.

Sandvik Materials Technology är världsledande inom rostfria och höglegerade stål, specialmetaller, motståndsmaterial samt processystem. Inom SMT drivs ett inköps- och råvaruoptimeringsprojekt (IRO) som har målet att minska lagernivåerna av köpskrot och legeringar i råvarulagret på skrotgården. Kapitalbindningen anses i dagsläget vara för hög. Därför är det viktigt att ta reda på hur det interna flödet av returstål ser ut, för att på det sättet kunna förbättra lagerstyrningen.

This paper is partially a literature study of human error and interruptions and partially an investigation of pilots and Air Traffic Control. The aim of the investigation was to find out where interruptions occur and how to reduce or eliminate them. The objective of this paper was to investigate what type of interruptions pilots and ATC deals with and during which phases they occur. The paper has revealed that private pilots causes more interruptions for ATC personnel than commercial pilots. The cause for this is probably the less experienced private pilot and the fact that Swedish is used before English by private pilots in communication with ATC.

The objectives of this paper are to discuss experiences from in-service courses, INSET, in the new school subject Technology..

The thesis demonstrates protection solutions that can be suitable for a camp during internationalmissions in order to resist complex threats. The threats could consist of small arms, machineguns,RPG 7, anti armour missiles, mortar, artillery, HPM-weapons, car bombs, biological and chemicalweapons as well as sabotage and theft. It?s not the technology itself that makes the threat scenariocomplex it?s the way the opponent acts during the operations. The opponent acts usually incivilian clothes and therefore he is difficult to distinguish from other civilians.
