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.

Beräkning av styvhet i lokaliserade enheter i jiggar med finita elementmetoden

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.

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.

Unga lagöverträdare - Samhällets kompromiss? : En studie av socialtjänstens yttranden

AbstractIn Sweden all persons under the age of 18 are considered children. The age when it is possible to be held responsible for a criminal act, and therefor convicted in court, is 15. Society?s and, perhaps first and foremost, the authority?s attitude towards juvenile crime is that they should not be equal adults in the process within criminal law. Because children are considered essential for the society of tomorrow, it is important to pay extra attention to crimes committed by juveniles.

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..

Analys av faktorer som påverkar interna leveransledtider : Dimensionering av lager

It is becoming increasingly important for companies to meet customer demands due to intense competition in today's global market, that forcing companies to improve their offerings and become better at managing their supply chain (Shen et al., 2006).  Long lead times can be reduced by using different methods and strategies shows various researches. Lead times occur in the planning, production, inventories and handling of products (Treville et al., 2003).The aim of the study is to develop a method to analyze the factors that affect the length of internal delivery lead time in manufacturing companies. The method also included suggestions for reducing delivery lead-time to internal customers.The main factors that influenced the length of the on delivery lead times has summarized to make a selection among the factors that can have the most significant impact. The selected elements will be used as a method to analyze how these areas affect a company?s length on internal delivery lead times.The study shows that the causes of the long delivery lead times was the location of the customer order point, uncertain forecasts, long material and production planning time, and long waits in the production and storage.The delivery lead time, according to this report?s suggested improvements reduced by centralizing CODP and makes more reliable forecasts.

Ställtidsreducering med hjälp av SMED i pressgjuterianläggningar

To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.

Projektledning : En studie om en effektiviserad projektledningsmetod till TS Produktion

The term "Project" have become a growing work model that exist in almost all bransches. A project is a work effort made over a finite period of time with a start and a finish to create a unique product, service, or result. Science shows that time limitation has an impact on humans to perform under pressure, which challanges the contributor to deliver. This report contains an examination about project management, both coming from scientific results and an external business. The point of this study is to bring ideas of improvement, which can make the work method more effective in this company..
