In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are introduced in the circuit and are then evaluated. The conclusions are that all investigated methods, pipelining, interleaving and voltage scaling, should be maximally made use of in order to minimize the power consumption..

Denna studie avser att undersöka och analysera fyra verksamma lärares uppfattningar om det vidgade textbegrepp som uttrycks i kursplanen i svenska 2000 och vilken betydelse deras uppfattning om det begreppet får för elevers undervisning i svenskämnet. Studien ska dessutom undersöka och analysera deras uppfattningar om hur ett vidgat textbegrepp kan förstås och relateras gentemot styrdokumenten i svenskämnet. För att fånga fyra lärares uppfattningar om ett vidgat textbegrepp och vilken betydelse deras uppfattning får för deras elevers svenskundervisning, har intervjuer genomförts i grundskolan med fyra lärare i år 6-9. Förhoppningen var att dessa intervjuer skulle ge en bild av verksamma lärares uppfattning om ett vidgat textbegrepp och hur det gestaltas i deras undervisning. Resultatdelen i uppsatsen upplyser om de fyra lärarnas olika uppfattningar om ett vidgat textbegrepp och vilken betydelse det får för elevers undervisning i svenskämnet.The purpose of this study is to examine and analyze the understanding, of four teachers, about the wide text concept as it is put in the Swedish curriculum of 2000, and what meaning their opinion has for their teaching in Swedish arts.

The main focus of this study is to describe how, and for what reasons teachers use literature and fiction as a pedagogic tool. A qualitative study was made by interviewing four teachers about their language teaching. Working with fiction as a teaching-aid in school can in many ways be favorable to both teachers and pupils. In terms of children?s language development, research shows that using fiction as an educational tool can stimulate pupils? well-being as well as their linguistic improvement.

Educators have an importance for the pupil?s progress, where the individual adjustment tutoring is varying. The pupil?s self-confidence is also individual and can be affected by the humans in the society. To find every pupil?s knowledge and enjoy creating and learning is a big part of an educator?s work.

This paper aims to examine how, and if, music is being used integrated in other subjects thanmusic in school. The study is based on qualitative interviews and I haveinterviewed fourteachers, regardless of whether they use music a lot or not.The questions the study is basedon are if there might be a connection between theteachers' own feelings for music andwhether they use music inschool or not, how music is being used and does the use of musicgive any effects?The result of this study shows that there can be a connection between the teachers ownsfeelings for music and the fact if they use music when they teach or not. One of the teachersI?ve interviewed had bad music experiences and didnot use music in her teaching.

This paper is about how the teaching profession have got a changed status from the perspective of the teachers. The papers cause is to find out how the teachers think that their status have changed in a period of 30 years. Interviews have been done with eight middle school teachers from two schools in the municipality of Södertälje. The answers from the interviews have been put in relation to theories in research of professions. Three hypotheses have been put up to apply the theories on the answers.

The purpose with this examination is to build a measureequipment to AerotechTelub AB (AT), who will registrate fault in SRAM-memory in contact with cosmic radiation. The equipment will be created around developcard from Memec Design with FPGA from Xilinx. The logic in the FPGA will be implemented with the hardwaredescribed language VHDL. The SRAM-memory that will be tested is build in CMOS-teknologi. The memorycells will be loaded with a predecided bitpattern.

World wide globalization and the rapid development of the Internet have lead to significant changes for companies around the world. The world has ?shrunk? and increased supply of goods and services has lead to a more intense competitive situation. As the market changes, so does consumer behavior. Today?s consumers do no longer wish to be treated as a group, rather they are looking for products and services that specifically fit their personal values.Recent years, the consumption of digital consumer electronics has sky-rocketed.

The aim of the study is to investigate how a teacher uses multimodal resources with an interactive whiteboard while teaching reading and writing. The aim is also to investigate what view the teacher has on using an interactive whiteboard while teaching reading and writing. Video-recorded observations and audio-recorded interviews are the methods used to collect data. The analysis was performed from a multimodal perspective and is also inspired by interaction analysis. The result of the analysis showed that the teacher uses several multimodal sign systems in combination with those found on the interactive whiteboard.

Scandicraft AB hade för avsikt att utveckla ett nytt målflygplan som skulle kunna nå Mach 0,5 på 50 m till 5000 m höjd. Detta med jetmotorer avsedda för modellflygplan. Flygplanet utformades för att kunna upprätthålla oaccelererad planflykt i Mach 0,5 på 50 m höjd. Vid analys framgick att flygplanets luftmotstånd var för stort. Flygplanets bränslemängd måste därför minskas från 40 kg till 13 kg.

AbstractIn this text the attitudes towards and using of blogs in teaching Swedish toteenagers will be explored. The results are based on a survey made amongst 17teachers and 58 students from all over Sweden. The end results show that theusage of blog still hasn?t found a permanent way into the classrooms, but has anappeal to and is being used by predominantly younger teachers both, male andfemale, with a positive response from students regardless of gender. Theconclusion is that using web tools like the blog is an easy first step for schools toconnect to the digital society of the 21stcentury and take advantage of the perksavailable in the digital classroom.Svensk titel:Blogg + Svenska =Sant? ?

This thesis is about Swedish and Serbian teachers and their views on how literature should be taught to students in high school. The twist is that these teachers live in two different European countries, and work under two different educational systems. Three of them work in Stockholm, Sweden and the other three in Belgrade, Serbia. The purpose of this thesis was to find similarities and differences in the practice of teaching literature among teachers in these two different educational systems. The teachers were interviewed separately and spoke freely about their views and methods when teaching literature.

The purpose of my study is to investigate teachers? opinions about learning difficulties in mathematics.I have read relevant literature on this subject. I have conducted interviews with seven class teachers, one special-needs teacher, a psychologist and one special-needs teachers who specifically worked with investigations concerning pupils with difficulties in mathematics.The result of my study shows that learning difficulties in mathematics can/might be prevented if children in pre-school are introduced to mathematics as early as possible. This should be done in a delightful way in their daily activities and while there are playing. I didn?t find any complete method to help children with mathematics difficulties in compulsory school.

Detecting small signals with a comparator demands that the total voltage offset is lower than the actual signal. The total offset includes the voltage offset in the comparator and the voltage offset that is created by the offset currents that flows thru the load at the comparators input. The goal with this comparator that has been developed has been that it will have a total voltage offset at maximum 500 uV. The comparator does not need to be extremely fast or does not need to operate in a big frequency area. To have all the flexibility that is needed a full custom technique is used.
