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.
Återkallning av Meningsbärande Enheter med Hjälp av Stödord och Internet : Ett kvasiexperiment för att undersöka återkallning av semantiskt meningsbärande enheter med externa hjälpmedel
The current study sought to examine if post-produced semantic memory cues are a good aid for memory recall. It also focused on remembering units with a meaning, instead of just remembering lists of words. In the current study a factual text was used where the participants were tasked with recalling as much information as possible either with the aid of cues (keywords written by the participants themselfs), computer with Internet or no aids at all. The results showed that keywords are significantly better for memory recall. The results were discussed in regards to modern models describing semantic memory.
Minnets betydelse för lärandet : En intervjustudie med tre pedagoger som arbetar med specialpedagogiska frågor
AbstractMy study is about working memory and working memory abilities for children with concentration difficulties. I have looked at literature and current research. I have also done an interview study on three pedagogues who have experience of the problem area.The conclusion I can draw from my investigation is, when it comes to working memory and what children with concentration difficulties can have problem with, is often shown when instruction is given in several stages and when the child come to the last instruction they sometimes have forgotten what the first instruction was. Special questions, image, image schedules and written instruction can help the child to remember. I also found that the pedagogues not only looked at working memory, but they also examined how the child hear and see, therefore they look at the ability of how the child notice what they hear and see and how they use it in their every day living.
Minnesallokering och debugverktyg
The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.
Kunskap och organisatoriskt lärande inom Apoteket AB
This paper aims to provide a description of how knowledge can occur in Apoteket AB, anorganization that is operating on the Swedish pharmacy market. The purpose of this paper isalso to describe how the organizational learning occurs in the organization, and how theoutcome of this learning can be stored in the organizational memory. This subject is ofinterest since Apoteket AB experience changes in their external environment in that they nolonger have monopoly to sell pharmaceuticals on the Swedish pharmacy market. Earlierresearch claims that organizations need to develop new knowledge in order to take action, andthis development needs to be supported by the management within the organization.The collection of primary data was done by two qualitative interviews with employees withinthe organization of Apoteket AB.Our conclusions are that knowledge can occur in many forms, such as tacit and explicitknowledge. The vast majority of the knowledge within the organization is the information thatcan be found in the electronic database Aponet within Apoteket AB, and that is useful for theemployees in their daily work, and therefore is known as explicit knowledge.
Lärande på hjärnans villkor : En fallstudie av ett antal klasslärares syn på begreppetarbetsminne och arbetsminnesträning
The study's purpose was to get a picture of what a number of class teachers know about and their views on the concept of working memory and working memory training and whether this affects their working and teaching in the classroom. The study is based on qualitative interviews and classroom observations and the theoretical perspectives that the study is based on two: didactic perspective and the socio-cultural perspective. The results of my study show that the class teachers' views and use of the concept of working memory is limited, even if they unknowingly working on parts of it in their teaching. All classroom teachers in my study term difficulties that can arise for students as concentration difficulties, which according to previous research can count towards deficiencies in working memory. All of the respondents in this study believe that it is mostly special education teacher who trains working memory, and that they themselves do not have that knowledge. They also believe that the classroom environment is important for all learning. Common to all respondents consider that the topic is important and would like to have more knowledge of how they can help and support pupils with poor working memory. As a special education teacher and teacher you often meet students who have trouble concentrating, and because of this may be difficult to absorb knowledge as when reading.
Picturing Words and Spelling out Pictures Semantic, phonological and spatial aspects of working memory capacity and processing and their implication for information layout
This study investigates verbal and visuospatial memory strategies used by individuals with perceptual or cognitive disabilities. The groups concentrated on in this study are deaf individuals who are native sign language users and individuals with dyslexia. The study comprises an experiment and an in-depth study in which a pre-test and a questionnaire were used. Nine deaf signers, two persons with dyslexia and 12 persons without any perceptual or cognitive constraints participated. Of these 23 persons, seven were selected to take part in the in-depth study.
Experimentell undersökning av provkroppar för trälimfogar
This thesis engages the topic of test methods for wood adhesives. Two test methods were evaluated, EN 302-1, a European standard, and ASTM D905, an American standard. The total amount of specimens manufactured and tested was more than 500. The adhesive bonds were tested in shear with an increasing load on the specimen until failure.The adhesives used were epoxy-resin, phenol-resorcinol-formaldehyde and a 2-K polyurethane. The test programme included five different types of intentional errors per method, in order to investigate the sensitivity of the test methods.
Kontrast och rörelse : relationen mellan glömska och sanning i Paul Ricoeurs Minne, historia, glömska och Martin Heideggers Vara och tid
What is forgetfulness? How does it show? Is it a part of memory or can it be considered on its own? In the philosophical discourse forgetfulness is limited and the phenomenon is mostly portrayed as a pathological or obscure counterpart of memory. This portraying of forgetfulness can be seen as traditional way of describing it, but there is some philosophers who has spoken of forgetfulness in more fruitful ways. These ways are not to be interpreted as aspirations to decouple forgetfulness from memory, rather they are to be seen as attempts to interpret this relation on another basis. This basis has also led this essay towards an interpretation of forgetfulness' relation to truth.
Nyckeln till arkiven : En kritisk diskursanalytisk studie om interoperabilitet och kollektivt minne
In the democratic process, of discussion and decision making, there is a need of reliable and authentic information. Archives are authentic and reliable information and also provides long term accessibility. But the public archives potential isn´t utilized enough at a societal level. The public archives are organized in a decentralised manner, and there are no common accesspoint at a national level. In the thesis this issue of accessibility and use at a societal level, is discussed in terms of collective memory.

Fel i produktionen : En studie om uppkomna fel i två anläggningsprojekt
AbstractThe purpose of this study was to identify problems that may occur in the execution of a civil engineering project and suggest measures to reduce the risk of errors. The study was conducted in cooperation with a civil engineering company in the Gothenburg area. During two weeks in February 2012, a field study took place on two construction sites where disruption and problems that took more than 15 minutes to correct were noted. During the field study we identified 39 such occurrences in the projects and then these were classified into different categories according to their cause.The two largest categories were "Design" and "Planning", which accounted for half of the errors that were discovered.In the study results were evaluated to decide whether it was possible to detect discrepancies at an earlier stage. The cost to fix an error in the design stage may be significantly less than to correct the problem in production.According to the evaluation, 55% of the errors could have been detected earlier if there was a greater degree of observation for such issues by everyone involved in the project.
När tiden står stilla går allt så fort : Objekt som minnesbärare
This master thesis deals with the theme of memory, it is through an artistic process I have investigated and peeled off to a specific memory, the hut. It is in the work of the personal memory through a craft process it transforms into something public. The hut is constructed out of corrugated boxes, corrugated boxes casted in clay. To cast an object differs according to me from sculpting the object; it is the function rather than the sensual feeling that is sought after. It is about the clarity and accuracy through the casted object that suggest something vague and indeterminate.

ADS och Matlab för optimering av pre-distortion av effektförstärkare
This master?s thesis deals with integrating simulations using Agilents Electronic Design Automation tool ADS with customized Matlab scripts, for solving complex analog and digital radio architectures. In particular, it addresses predistortion, realized in the digital domain, of power amplifiers, modeled in the analog domain. The former is implemented in Matlab while the latter is implemented in ADS. Two versions of integrating the two systems have been tested: 1) Iterative approach on sample basis and 2) Scheduled batch solution by matrix inversion.
