Optimering av multiprocessorsystem med hjälp av schemaläggning

A well known optimization-problem of multiprocessor system is scheduling of tasks. In this paper I use a variant of previous known algoritm, (Fast Critical Path) for scheduling real-time tasks on a multiprocessor system. This is made in a simulation study in MATLAB. The system architecture is assumed to be a MIMD- machine, (Multiple Instruction stream Multiple Data stream) with bus-typologi and message-architecture. Scheduling was made on this system where the number of processors varying from five to ten.

Möjligheter och begränsningar med läroboksbaserad och laborativ matematikundervisning

Mathematics is a central topic in today's education debate, including discussion of its educational quality and various teaching methods. Today basically two different teaching methods are used; one is the textbook based method, with the book in focus and the other one the laboratory method by which teaching is performed through practical applications. The purpose of this study was to examine four primary school teachers' view of these two teaching methods by means of four relevant inquiries. By interviewing the four teachers, advantages and disadvantages were highlighted and the purpose was achieved. In order to support the analysis, two theories applied; the socio-cultural perspective and the cognitive perspective.

När jag är stressad är jag inte den pedagog jag vill vara : Pedagogers stress på förskolan

AbstractThe purpose with the study is to contribute knowledge of teacher?s thoughts of, and actions in potentially stress filled situations at preschool. The methods I?ve been using are qualitative interviews and unstructured observations of hallway situation at dressing and the transit between lunch and rest.At the interviews with the teachers it showed that none of them feels stressed but there are stress filled situations. The lunch and transit between lunch and rest is a stressful situation, where there is a lot to do, like the dishes, the teachers break and the lie-down.

The impact of platelet storage time on transfusion results

Platelets are small fragments, but they are of crucial importance for the coagulation. The risk of spontaneous bleeding increases when the level of platelets falls below a thrombocyte particle concentration threshold value of 50 x 109/L. In those cases a platelet transfusion might be compulsory. Ongoing research tries to improve the quality of the platelets and to increase the safety of the method used. However, we still need to better understand which factors that affect how patients react upon platelet transfusion.

Gymnasielärares informationssökning: En studie av samhällskunskapslärares informationssökning i yrkesrollen

The aim of this thesis is to examine Social science teachers infor-mation seeking in their professional role.The focus in this study has been on what sources the teachers use for information seeking, examine and analyze their information practices and how they state their reasons for using different in-formation sources, and finally how these teachers experience con-ditions related to information seeking and how these conditions in-fluence their information seeking.This study is based on four semi structured qualitative interviews. The empirical material from the interviews has been compared to earlier relevant research and analyzed with a theoretical frame-work, which includes conceptions from a sociocultural perspec-tive, a matrix over different kinds of information sources devel-oped by Höglund och Persson and McKenzie?s model of infor-mation practices.The results of this study are:- These teachers use both formal and informal sources and external and internal sources. Digital sources are important and these have consequently been added to Höglund och Persson?s original matrix from 1985.- Information practices tend to overlap each other, for example ac-tive seeking (more specific and prepared information seeking) and active scanning (less specific), which are the two most common information practices among the teachers.

Svenska som andraspråk : En kvalitativ studie av utformningen av undervisningen inom andraspråksinlärning

The purpose of this qualitative study is to understand and examine the problem andreason why second language pupils have difficulties reaching the goals of thecurriculum in ?Swedish as a second language?. The study is based on interviews withtwo second language teachers and Vygotskijs and Antonovskys theories. The interviewswith teachers gave a broader view on why these difficulties exist and whatconsequences might occur. This analysis shows that there can be different reasons as towhy pupils can not reach the goals in their second language that are set for them.

Att vara pappa : Att hantera ett litet barn - känslor och tankar runt papparollen

The need of knowledge revolving first-time father experiences, feelings and thoughts is extensive and insight and knowledge about his emotional life in conjunction with being a dad is equally important. The purpose with this study is to investigate how men, that recently became a first-time father, manages and experience the first time with his child. We used a narrative method and interviewed seven fathers as we conducted our qualitative interview study. All the fathers went through life changes. No one talked about sacrifices, but noted rather that their lives were to become different.

Relationen är kunskapens moder. En kvalitativ studie om lärare som kränker elever.

According to reports from the department of education the majority of school children consider school as a place for happiness, security and development. However, one of ten children experience cruelty and abuse on a daily basis and research shows that children are more often violated by their teachers rather than their peers. In year 2006 legislature decided that school children needed to be protected from the harmful abuse and bullying from other children as well as their teachers. Despite the law approximately 50 000 children are the victims of adult abuse in school every year. Meanwhile science also proves that teachers dare not, for different reasons, confront colleagues when witnessing violations of children.

Stereoseende i realtid

In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. The blockmatching method performed better than the phase based method, both in speed and accuracy. SIMD operations (Single Instruction Multiple Data) have been used in the processor giving a speed boost by a factor of two..

Olika metoder och tekniska hjälpmedel för att bestämma bevattningstidpunkt :

This examination work on studies and research in articles is mostly from other countries. The purpose of the examination work have been to find out if there are any means you can work with to find out when its time to start irrigation, how they works and if they are credible. In Sweden there is not many means for decide when it?s time to irrigate and how much water you should appear. Swedish farmers think they have so much experience that they don?t need techniques like this.

För ett socialt kapital av god kvalité : - Det förebyggande arbetet mot mobbning ur skolkuratorers och lärares perspektiv

The purpose of this study was to understand school counselors´ and teachers´ perspectives on the prevention of bullying in relation to social capital. The study was based on a qualitative process with semi-structured interviews from three teachers and three school counselors from three different schools. The main question was to find out teachers and school counselors perspectives of bullying in relation to social capital. The analysis was based on a theory that focuses on social capital, where trust and confidence as well as universal and selective interventions are important. Today, bullying is considered a serious and significant problem in school.

Småbarnsavdelningar - bara barnpassning eller? : En kvalitativ studie om verksamheten på småbarnsavdelningar

In the curriculum for Swedish pre-school the focus is mainly on five concepts. These are care of the children, learning, influence, rearing and security. These concepts are to characterize the activities of the pre-school in Sweden.Back in time the focal point of pre-school activities for young children was mainly on security. The learning part became more prominent as the children grew older. When speaking to teachers and parents I do sense that some believe this is the case even nowadays.

Det första mötet : Jämförelser av första-gången-händelser rapporterade av mödrar och fäder vars barn vårdats enligt kängurumetoden på två neonatalavdelningar

Aim: Compare occurrences of first-time-events reported by mothers and fathers with children at high tech NICU according to kangaroo-mother-care method in two university hospitals. Method: Descriptive, quantitative design. Fourty-five couples of parents, with premature children born and cared for at university hospitals in Uppsala or Örebro, answered questionnaires about first-time-events: interaction-events, measures-of-care-events and sleeping-place-events. Results: All differences regarding the children?s age at first-time-events showed Uppsala-children to be younger than Örebro-children. Interaction-events were reported first in children?s lives, measures-of-care-events and sleeping-place-events later.

Behaviour and throughput of dairy cows when entering and exiting two types of parallel rotaries

Today a trend can be seen towards fewer dairy farms and increasing number of cows per farm. Larger farms set a higher demand of more labour efficient milking systems. The time to enter and exit milking rotary platforms is crucial to maintain a high cow throughput. This study is a project initiated by DeLaval in order to evaluate the cow throughput and cow behaviour during entry and exit in two types of parallel external rotaries with different bail designs. The two rotaries compared were DeLaval parallel rotary PR2100 and PR3100HD.
