Heuristisk profilbaserad optimering av instruktionscache i en online Just-In-Time kompilator
This master?s thesis examines the possibility to heuristically optimise instruction cache performance in a Just-In-Time (JIT) compiler. Programs that do not fit inside the cache all at once may suffer from cache misses as a result of frequently executed code segments competing for the same cache lines. A new heuristic algorithm LHCPA was created to place frequently executed code segments to avoid cache conflicts between them, reducing the overall cache misses and reducing the performance bottlenecks. Set-associative caches are taken into consideration and not only direct mapped caches.
Dåtidens betydelse för nuet och nuets betydelse för dåtiden : Skildringar av påskupproret på Irland 1916
In this essay, I compare ten different depictions of the Irish Easter Rising of 1916. These depictions are all from books published between 1924 and 2000, which deal with a wider context of the history of Ireland or Northern Ireland. I relate the depictions to the point in time when they were written, the geographic focus of the book, and the views that the author expresses about the present and the future, and about the significance of history. The main result of my essay is that the depictions differ in a way that seems connected to whether or not there was an ongoing violent conflict in Ireland at the time the books were written. Texts written when the political violence was present, or close, in time and location, are likely to be written either in a neutral tone with concern about objectivity, or incorporating the Easter Rising events in context of an ongoing socialist struggle.
Utvärdering av ett system för Rapid Control Prototyping inom området robotstyrning
In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.

Today there is a research project undertaken by the Swedish University of Agricultural Sciences along with Wången (a highschool specialized in trotter training), which focuses on trotting horse training, performance and health. The project investigates how exercise intensity and feeding strategies affect the development of growing horses.
The project includes two groups of horses where all 16 horses are fed in the same way. One group of eight individuals are trained 100% compared to conventional training and the other group are trained 20% less than the other group. All horses are trained twice a week and are out at pasture beyond that.
Elever som hänger med : en kvalitativ studie om skolsituationen för elever som enkelt klarar skolans uppnåendemål
The purpose of this research has been to find out whether and how teachers stimulate and motivate well achievers in the elementary school to reach a higher level. To gather information I visited two different schools within the same county in Stockholm and on each school I met and interviewed with two teachers. The answers received from these interviews are presented in this study as my results. I found that the teachers feel that students that do well in the classroom many times work as role models for the other students. Often these students require extra material as they usually finish their workload ahead of others.
En undersökning av Quicknets Customer Relation Management
This report is focused on a research to find out if the Customer Relation Management (CRM) of Quicknet AB works and if their customers are satisfied with it. During this investigation I tried to see if the customers had a need for taking the CRM and use a tool called Social CRM. The report will conclude if the clients of Quicknet think that there is something that can be done in the relation between both parts and how it can be improved. At the same time I am going to build an application which relates to the problems of this report.To solve the problem I am going to do a survey which will include the CRM and also try to find out if the customers of Quicknet share the same thoughts about having a Social Customer Relation Management. Also if this survey shows what the customers think about the CRM, it could improve the relation between Quicknet and themselves. The result from the survey showed two things.
Fysisk aktivitet för elever med koncentrationssvårigheter
Abstract This examination work is about the role of physical activity for students with concentration difficulties. The purpose of this work is to describe educators experiences of how students with concentration difficulties are affected by physical and motor activity during school-time in primary school. In the work I assume from my questions that are: How do educators experience students with concentrations difficulties? Do educators think physical and motor training during school-time matter for the students learning processes? How? Do students with concentration difficulties have other possibilities than other students regarding physical and motor activity during school-time? I am using a qualitative interview method for answering my questions. The interviews are conducted in collaboration with three educators in a medium-sized Swedish F-6 school.
Exkursion ? ett lärandetillfälle? : Lärare och elevers uppfattningar om exkursioners betydelse för lärande i ekologi
The main purpose of this study was to obtain insight into what students and teachers think about field trips in ecology and whether they think that fieldtrips result in increase of students? learning. Open questionnaires and half structured interviews were used to investigate this. Persons who answered the questionnaires and participated in the interviews were senior high school teachers in biology or science and high school science students. All the teachers and most of the students thought that field trips in ecology resulted in increased learning.
Energiåtervinning : av kompressorkylvattnet
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.
Portföljoptimering som alternativ till indexfonder : Hur skulle en fond konstruerad enligt portföljoptimeringsmodeller utvecklas i jämförelse med index?
This paper investigates the possibilities to construct automatized portfolios based on optimizations strategies that could outperform comparable indexes. The study is based on time-series of Swedish stocks dating from 1986 to 2006. In the research four different portfolio optimization techniques were studied. These were: the Classical Markowitz Approach, Mean-Absolute-Deviation, Minimum-Regret and Conditional Value-at-Risk of which the three latter are based on generated scenarios. The behaviour of these models was studied for different choices of parameters such as backward time-horizon and targeted average return.
Vikten av icke-diskriminering, barnets bästa och att få höras : - En studie i hur asylsökande barns rättigheter tillgodoses i svensk rätt respektive i Rawls rättviseteori
The purpose of this master's thesis is to examine children's communication and interaction during story time at the public library. The aim is also to examine how to develop the story time ? in terms of participation and equality ? at a specific library.Action research was used as a research strategy and participant observation, log, tutoring and interviews as methods to collect data. Since action research is done on the basis of practice, a significant collaboration with the librarian and the participant children is taking place within this study.Research from the fields of Library and Information Science, Education and Childhood Sociology form the interdisciplinary research area to which this study links. The theoretical framework consists of theory and concepts from the Socio-cultural Perspective, Poststrucuralist Feminism and Childhood Sociology.
Barn och stress.
The purpose of this study is to show how the modern society, with demands, expectations and the time constraints of adults, affects children and the everyday life at the preschool. Our intention is also to show the importance of identify stress symptoms of the children. The study is of qualitative empirical kind and is based on a questionnaire to 19 parents of preschool children at the age of three to five years old. Interviews are made with four preschool teachers on one preschool. An observation of children in possible stressful situations is made during three days each at two preschools. The results show that the modern society affects children and can be stressful. It also affects the everyday life at the preschool.
Övergången från natur till kultur
Göbekli Tepe is an 11000 year old religious center where Totem has been exercised. It was raised by megalithic hunters and collectors that still during the construction lived in small-scaled mobile groups in order to find food and therefore should not have had time to raised costly stone monuments. The religious center consists of four enclosures with two T-pillars decorated with pictures of different animals and birds. Any dwellings have not been found. The place has been constructed by a well-organized elitist organization that has been capable of raising constructions in order to exercise their religion in a way we did not thought was possible such a long time ago. Analysis and findings from the near east existing from this time shows however that social changes happen in the communities around the region. Can archeological finding from the excavations on the religious center give any answer or clue regarding how man came to develop from hunter and collector to farmer? Do the findings reveal that the religion has changed Mans way to think and organize so that she was prepared to introduce the agriculture that occurs? The aim of thesis is to clarify whether Göbekli Tepe has played any role in the complex origin of agriculture..
Opera i Stockholm, Stadsgårdskajen
The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..
Det stormar i öster - en prognos över Turkiets EU-kandidatur
Turkey has taken part in regular negotiations to gain membership in the EU since 2005. At the same time is Turkey a candidate that stands out from those of earlier rounds of enlargement, and its possible membership got both supporters and critics amongst the Unions member countries. The aim of this thesis is to, trough a textual analysis, investigate the prospects and obstacles Turkeys candidature faces. The material consists of documents from a number of think tanks connected to the European Commission, as well as the Commissions own documents regarding Turkeys negotiations.A recurring picture is that Turkey is treated differently then earlier candidates, and that the Commission has a hard time keeping an unambiguous line in its negotiation frame. The material of the think tanks attributes the public opinions distrust of the member countries of EU as a hindrance, and Turkeys meddling in the conflict on Cyprus is problemized.
