Individuell mätning av hushållsavfall i flerbostadshus : ?Ett incitament för minskad klimatpåverkan?

The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.

Högeffektslysdioder. Möjligheter och förutsättningar för högeffektslysdioder som belysningskälla - ett demonstrationsbygge

This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

Elcyklar och dess möjlighet till uppladdning under drift

Today?s environmental discussions have led to more progress in the different transportareas. To ride a bicycle is often one of the most efficient alternative when it comes totransport. An Electric bike is, and makes transportation more efficient than a regularbicycle. Electric bicycles do not affect the environment significantly and allows moreconvenient transportation than ordinary bicycles do.

Reducering av effektförbrukning i inbyggda system med Linux

Linux is a growing operating system in embedded systems. Today, Linux is not only in heavy servers but also in cell phones, PDAs, cameras and other devices running on battery power. While current technology is more energy efficient, more and more technologies are implemented into a single unit resulting in an overall increase of power consumption.Low power consumption is an increasingly important feature of a system today. Lower power consumption means lower costs, less environmental impact, and longer life for applications that runs on batteries.This work compiles methods to reduce power consumption of Linux systems. The work includes examining whether the available opportunities are platform-specific or of a more general nature.

Språkliga och kognitiva förmågor hos barn med läs-och skrivsvårigheter : En jämförelse med barn med cochleaimplantat

Children with Reading and Writing Difficulties and Their Language and Cognitive AbilitiesA Comparison with Children with a Cochlear ImplantAbstractThe aim of this study was to examine the cognitive abilities that are important for reading in children with reading disabilities, children with a cochlear implantation and typically developed children. 64 children aged 10-12 years participated in the study. To answer the question at issue we used the following tests: Block Design from WISC III, PPVT III, TOWRE, SL 40 and a few chosen tests out of the SIPS battery. On tests of the lexical access children with reading disabilities performed at the same level as hearing children, while the children with a cochlear implant performed significantly lower. Test of the phonological and complex working memory showed that children with reading disabilities performed significantly higher than children with a cochlear implant, but at the same time lower than typically developed children on the test of phonological working memory.

Implementering av "Life Cycle Management" i svensk läkemedelsindustri

It generally takes 10 to 12 years for a new drug to hit the market. The pharmaceutical industry invests huge sums in these early stages of research and development. In spite of the rapidly rising research and development expenditures fewer and fewer blockbuster drugs are being developed. Longer lead times and aggressive generic post-patent competition have narrowed the timeframe for the pharmaceutical companies to profit on their investments.In the face of these threats the pharmaceutical industry has developed a battery of strategies to prolong market exclusivity and to maximize return on investment. These emerging strategies are commonly known as Life cycle management (LCM), which actually is more of a concept than a method.

Upplevelserna av medarbetarskap i äldreomsorgen i Hagfors kommun

The teaching of modern foreign languages within Swedish educational system has been a subject of a number of alarming reports in recent years. Several studies have shown that students lack motivation to learn any language but English. Of particular concern is the young males? underachieving and disinterest in foreign languages. In the meantime, a number of international studies and the statistical data from Swedish national agencies of secondary and higher education (Skolverket and Högskoleverket) have indicated that Russian is one of the languages that are favoured by males. The primary goal of my case study was, therefore, to examine students? motivation to learn Russian and their attitudes towards language, community and Russian-speaking people.

Testbatteri för talapraxi : Utformning och pilotnormering av ett artikulationstest

Talapraxi är en talmotorikstörning som drabbar planeringen och programmeringen av talet, vilket visar sig som avvikelser i artikulation och prosodi. I dag finns inget svenskt test för utredning av talapraxi. Syftet med studien var därför att utforma ett testbatteri på svenska som är känsligt även för lindriga grader av talapraxi. Detta test pilotnormerades på 50 friska deltagare.  För att kunna studera hur kön, ålder och utbildningsnivå kan inverka på prestationen i testbatteriet, eftersträvades en jämn fördelning när det gäller dessa demografiska bakgrundsvariabler.Uppgifterna konstruerades baserat på tidigare forskning gällande de typiska perceptuella dragen vid talapraxi och på testuppgifter som tidigare har visat sig vara känsliga för talapraxi.Deltagarnas prestation varierade mellan testbatteriets olika uppgifter. På några uppgifter hade en stor andel av deltagarna alla rätt, medan andra uppgifter visade sig vara utmanande även för friska personer.

Utveckling av kognitiva färdigheter och läsförmåga hos barn med mild och måttlig hörselnedsättning i ett ettårsperspektiv

The capacity to process and to remember information is a basic condition for language ability and for coming reading ability. Reading ability is strongly connected to phonological awareness, receptive vocabulary knowledge and working memory capacity. In what way hearing impairment in children affects development of cognitive skills and later on reading ability is an area that has attracted minor attention for research.The aim with this study was to investigate changes in cognitive skills and reading ability in children with mild or moderate hearing impairment after one year of progress and furthermore if any connections between any increases of the abilities were to be found. Comparisons were made with results from age adequate normal hearing children. Moreover prosodic ability on word-level was tested this year.
