Sparse matrices are often used in numerical algorithms that solve linear equation systems. Many methods for storing sparse matrices have been proposed and implemented during the years. These methods focus primarily on minimizing the total memory consumption and the time that it takes to store a sparse matrix. This report researches the available storage methods for sparse unstructured matrices. The formats that are researched and implemented are COO, CRS and ELL.

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.

An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.

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.

Place as a concept, and memory as a phenomenon is researched through literature studies. The essay investigates how we think about place and how we experience and relate to it. Memory is discussed both as personal memory and collective memory. Place is a strong source of memory. When we return to a place, we recognize not only the place itself, but also the things we did there, the people we met and the thoughts passing through our mind when we last were there. Pieces of ourselves are stored in the memories awaken when we revisit a place.

The aim of my thesis was to investigate in what grade teachers who work within special education make use any methods to train the working memory of their students to improve learning ability. I also wanted to examine the material used to train working memory and if any results were noticed. My choice of method was qualitative semi-structured interviews that were recorded during the interviews I conducted these in five different school with education for children with intellectual impairment. The result shows that the schools that are aware of recent research on working memory training had methods for training with their students. They could also see a result that shows that working memory can be improved with training.

The purpose with this thesis is to investigate how a number of municipalities in Stockholm County proceed when they allocate land and establish land allocation agreements for exploitation, and to investigate how a number of municipalities define land allocations and land allocation agreements on the occasion of public land sales. The aim of this thesis is to describe the allocation methods a municipally uses when they offer land for sale and to give an insight regarding which correlation different land allocation agreements have in different municipalities.Methods used are: (1) a literature review where the underlying theory for land allocations and land allocation agreements have been studied; (2) a questionnaire have been done to complement the literature review and to provide a picture of how a number of different municipalities in Stockholm County use and apply land allocations; (3) an agreement audit have been done to see the extent to which different agreement terms exists.Responses from the questionnaire, together with the definitions form different municipality?s land allocation policies and the literature review, resulted in a definition of a land allocation and a land allocation agreement. The agreement audit shows that agreement terms regarding: price or price indication, location, cost-sharing and planning costs are the most common agreement terms within the municipalities we have investigated.The study suggests that there is some confusion regarding land allocation agreements and the meaning of these, that became apparent when agreements where gathered, despite a careful explanation that it was land allocation agreements we requested, we still got exploitation agreements and purchase agreements. Therefore, we consider it necessary with an official definition of a land allocation agreement well anchored in the Planning and Building Act together with the rules of development agreements or other legislation.That there is a lack of research within the subject becomes evident when reports, essays, and other literature generally refers so the same sources.Keywords: land allocation, land allocation agreement and public land sales.

Background: When firms grow through acquisitions it is commonly debated whether the two entities ought to be better off as standalone companies rather than as a merged company. This thesis aims at discussing this issue of M&As advantages and disadvantages in terms of source of synergies from the perspective of resource allocation. Purpose: The purpose of this thesis is to describe and analyze to what extent pre-M&A differences (against similarities) in resource allocation and corporate culture between the acquiring and target firm have an impact on the post-M&A performance. Theoretical framework: Efficient market hypothesis, resource based view, strategic fit. Methodology: A longitudinal study is conducted on the EU market during 1992 to 2002 based on balance sheet and income statement data.

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.

This study was conducted to investigate the relationship between perceived popularity, social information processing and working memory. With the intentions of examining popularity 209 (98 female, 111 male) children in second and fourth grade were presented with a roster of their classmates and were to nominate whom they liked and whom they disliked. To study working memory capacity a working memory test, that places demands on the participant to work both with and store the given information, was used. To examine children's cognitive processing of empathy-provoking information a cognitive appraisal interview was conducted. The results imply (a) that working memory increases with age, (b) that there is a weak relation between working memory capacity and popularity, and between popularity and cognitive processing styles and (c) that there are some strong correlations between working memory and cognitive processing styles..

Apart from recognizing and neutralizing threats, antibodies also have the ability to regulate immune responses against their specific antigen. IgG administered together with erythrocytes is well known to induce >99% suppression. This has been used to prevent haemolytic disease in new-borns since the 1960's, but the mechanism behind it is still not completely understood. The effect on the primary response is well established, but its influence on induction of immunological memory is still heavily debated. In this study adoptive cell transfer of splenocytes to irradiated mice was used to survey the effect IgG has on induction of immunological memory without disturbance from the primary IgG response.

The purpose of my independent work was to develop and test a task-specific assessment matrix to the students writing logs that occurs in connection with their APL (workplace-based learning). The matrix is based on upper secondary school subject plan House building from The Swedish National Agency for Education and the four courses House building process, House building 1, House building 2 and House building 3 - conversion. Due to the matrix structure, I used the example matrix of Malmö University. The task-specific assessment must both serve as a guide for students in the implementation of the log writing, and in the evaluation of the assessment work. Both students and teachers then get a common assessment tool for evaluation.

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.
