Fonologisk medvetenhet i förskoleklass : En interventionsstudie

International studies show that literacy skills have deteriorated among Swedish students. Empirical evidence states that before being able to learn to read it is important to have phonological awareness. From this perspective, an intervention study was launched to examine whether pupils´ phonological awareness could be enhanced through the work of a special model during a limited time. The aim of the study is to investigate whether six pupils in preschool develop phonological awareness based on Bornholmsmodellen during a limited period of time. The control group was made up of the remaining pupils in the preschool class.

Utarbetning av källsorteringsstandarder : monteringsfabriken på Saab Automobile AB

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

Urshults Knektar : En studie om vad som hände de indelta knektarna från Urshults rotar 1709 till 1718

This essay examines what happened to soldiers from Urshult in military service of Sweden during the diminished power of the country in the beginning of the eighteen century. Information of interest is taken from the soldiers? age, time of service and other annotations of interest that shows to be helpful when examining their fate.  First off, this study explains Sweden?s situation during this period of time. To get a grasp about the situation, allotment is explained as well as the most important events in the big Nordic war. This study is based on qualitative content analysis and GMRs are used as its main resource of information and consists of empiric analysis.The result of this paper shows that very few soldiers from Urshult were able to return home alive.

Uppfattningar om utomhuspedagogik hos lärare i grundskolans årskurs 4-6

The use of out-door pedagogy in the school has been frequently high-lighted during recent years. To which extent out-door education was practised in the school depends on the opinions among the active teachers. The aim of this study was to examine the opinions on out-door pedagogy among teachers in classes 4-6 of the elementary school and to find out to which extent the teacher used out-door teaching. The study was based on qualitatively structured interviews with 4 teachers having different lenght of teaching experience. The results of the interviews showed that the teachers had different opinions on the definition of out-door pedagogy.

Processchemaläggare för mångkärniga processorer ? Fördelning av minnesbelastning i NUMA-system

For systems with multicore processors contention for shared resources is a problem that occurs when several memory-intensive processes are executed in parallel within the same memory domain. This contention has a direct influence on the performance of the system and is a complex problem that has been recognized for a long time. An attractive and actively studied way to minimize this problem is by using a process scheduler adapted to allocate processor cores in a way such that contention for shared resources is minimized.With the introduction of multicore NUMA-systems (Non-Uniform Memory Access) the situation has become even more complex. In these systems the access time for processor cores to different memory domains vary depending on factors such as distance and load. Thus, the process scheduler also has to consider where the memory of each process is placed to minimize the distance and balance the load on each memory domain.This report presents a user-level process scheduler for a NUMA-system based on the multicore processor Tilera TILEPro64.

Jämförande simulering och modellering av framtida järnvägars elenergiförsörjning

In this thesis, the Train Power System Simulator (TPSS) has been compared and verified with the commercial simulator TracFeed® Simulation (TracFeed). The basis for the comparison was a given part of the Swedish railway system, with steel transportation trains. Primarily, emphasis was placed on running time and energy consumption in simulation results. Two transformer systems were analyzed, booster and auto transformers. The high voltage transmission line, parallel to the railroad track, was disconnected in some simulations.

Aktiv förvaltning av fonder på Emerging Markets

The main purpose of this Master Thesis has been to evaluate whether active fund management is profitable on Emerging Markets. The material used to examine this consists of 106 actively managed funds, with varying length during the period 1988-2006 and who uses MSCI Emerging Markets (MSCI EM) as benchmark index. The thesis has been written under the supervision of the Asset Management Department of Länsförsäkringar AB (LFAB) and the Department of Production Economics, Linköping Institute of Technology. Apart from the main purpose, the methodology used is also meant to form a template for in-depth or similar studies, preferably by the assigner of this survey, LFAB.The results shows that the median manager underperforms the MSCI EM throughout the whole period, which leads to the conclusion is that active management on Emerging Markets is not profitable. A grouping of the funds based on tracking error still shows that a majority of the managers in all of the groups underperforms against the benchmark.

Barns upplevelser av att leva med övervikt eller fetma : en litteraturstudie

This study aimed to describe children?s experience of living with overweight or obesity, by using a literature-review. The study includes eleven articles, data is from children between ages 5-15 year. The result occurring were in the areas; Quality of life and self-esteem, Social company, Body concept and weight reduction and Psychological unhealth. BMI above what is recommended gives a negative influence on quality of live and self-esteem.

Implementation och utvärdering av Mimer SQL Real-Time på INtime RTOS.

Virtualisering är en ökande trend där man istället för att ha en separat hårdvaruplattform förvarje system, så exekverar flera virtuella system på en och samma maskin. Dessa system kanha olika egenskaper och krav, exempelvis kan ett delsystem med hårda realtidskravinteragera med ett annat delsystem utan realtidskrav. Ett exempel på detta är ett industrielltstyrsystem där ena delsystemet samlar in tidskritisk systemdata i realtid medan det andradelsystemet utför icke tidskritiska åtgärder som är baserad på denna information, som tillexempel att grafiskt åskådliggöra systemstatus.Att dela upp system mellan olika virtuella delsystem ställer höga krav på delning av data. Ettsätt att dela data på ett säkert och strukturerat sätt är att använda sig av en realtidsdatabas.I detta exjobb har vi undersökt möjligheten att anpassa den kommersiella realtidsdatabasenMimer SQL Real-Time Edition för att användas i det virtualiserbara realtidssystemet INtime.Arbetet omfattar undersökningar av olika modeller för delat minne samt synkroniseringmellan systemen. Resultaten av dessa undersökningar har inkorporerats i en version avMimer SQL Real-Time Edition anpassad för virtualisering i INtime.

Matematisk generering och realtidsrendering av vegetation i Gizmo3D

To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

Just In Time : Effektivisering av materialflöden med hjälp av principer från Inventory Management och Production Management

AbstractManagement is a field that started getting attention in the beginning of the 20th century by Frederick Taylor. His publication is called the Principles of Scientific Management and is based on the principles of using scientific methods to find the best way of conducting each operation within a production facility. Many of Taylor?s principles may appear obsolete today but the matter of an effective material flow is still highly current. Efficiency is the relationship between the input into an operation and its result.

Voice onset time hos svenska förskolebarn : Ett utvecklingsperspektiv

Voice onset time (VOT) är en akustisk tidsparameter som speglar den talmotoriska kontrollen. VOT anses vara det mest tillförlitliga akustiska tecknet på om en klusil är tonande eller tonlös.Syfte: att undersöka och jämföra VOT hos barn i åldrarna 3, 4 och 5 år samt jämföra med tidigare publicerade svenska vuxenvärden.Metod: 83 barn (51 flickor; 32 pojkar) ljudinspelades vid produktion av minimala par för de svenska klusilerna.Resultat: medelvärden för VOT minskade genomgående med åldern. Signifikanta skillnader erhölls mellan 3- och 5-åringarna för ljuden /t k b g/ samt gällande användandet av förton för tonande klusiler. Jämförelser med vuxenvärden visade att vuxna i högre utsträckning hade förton för de tonande ljuden och kortare VOT för de tonlösa ljuden än de, i föreliggande studie, deltagande barnen. Inga signifikanta könsskillnader påträffades.Resultaten av föreliggande studie kan användas som referensmaterial vid bedömning av barn med talmotoriska störningar..
