Beslutsprocesser och informationshantering : en fallstudie inom en högskoleorganisation / Decision processes and information management : a case study within an academic organisationWodlén, Anna-Carin, Åmand, Ing-Marie January 2008 (has links)
The purpose of this thesis, was to study decision processes and the importance of information management in the processes within an academic organisation, which led to the work with adaptions according to the law of Equal Treatment of Students in Higher Education, (SFS 2001:1286). A general question was formulated concerning how different information- and knowledge flows interact within an academic organisation and its library during the decision processes. The questions at issue we have tried to examine, concern the factors that have influenced the participants´ choice of information during the decision processes, in their work of adapting the law of equal treatment, and how these choices have influenced the priorities that were made. The theoretical starting point was basically Cohen, March and Olsens Garbage Can Model. We also found the author Chun Wei Choo´s descriptions of organisations, as systems of information processing, useful for parts of our thesis, especially the parts that deals with the role of information management within the decision processes. To answer our questions interviews were made with seven participants who had been involved in the work concerning the adaption of the law. The result shows constantly present interaction between the information- and knowledge flows during the decision processes. New information is processed continuously by the participants. The information processes can be transformed to knowledge in sense making processes, and be useful when the information- and knowledge flows coincide with each other and provide opportunities for decision making. / Uppsatsnivå: D

Surf: an abstract model of distributed garbage collection.Brodie-Tyrrell, William January 2008 (has links)
Garbage collectors (GCs) automate the problem of deciding when objects are no longer reachable and therefore should be reclaimed, however, there currently exists no automated process for the design of a correct garbage collector. Formal models exist that prove the correctness of individual GCs; more general models describe a wider range of GCs but do not prove their correctness or provide a concrete instantiation process. The lack of a formal model means that GCs have been designed in an ad-hoc manner, published without proof of correctness and with bugs; it also means that it is difficult to apply experience gained from one implementation to the design of another. This thesis presents Surf, an abstract model of distributed garbage collection that bridges the gap between expressibility and specificity: it can describe a wide range of GCs and contains a proof of correctness that defines a list of requirements that must be fulfilled. Surf’s design space and its requirements for correctness provide a process that may be followed to analyse an existing collector or create a new GC. Surf predicts the abstract behaviour of GCs; this thesis evaluates those predictions in light of the understood behaviour of published GCs to confirm the accuracy of the model. A distributed persistent implementation of the Train Algorithm is created as an instantiation of Surf and the model is used to analyse progress in the GC and drive the design of a partition selection policy that provides a lower bound on progress and therefore reduces the GC’s complexity to completeness. Tests with mesh data structures from finite element analysis confirm the progress predictions from Surf. Published GCs cluster mostly in one corner of the Surf design space so this thesis explores the design of a GC at an unoccupied design point: the Tram Algorithm. Analysis via Surf leads to the prediction that Trams are capable of discovering topology in the live object graph that approximately identifies the strongly connected components, permitting O(1) timeliness that is unique to the Tram Algorithm. / Thesis (Ph.D.) -- University of Adelaide, School of Computer Science, 2008

Generationsskräpsamling med explicit kontroll av hårdvarucacheKarlsson, Karl-Johan January 2006 (has links)
<p>This report evaluates whether an interpreted high-level garbage collected language has enough information about its memory behaviour to make better cache decisions than modern general CPU hardware.</p><p>With a generational garbage collector, depending on promotion algorithm and generation size, around 90% of all objects never leave the first generation. This report is based on the hypothesis that, because of the low promotion rate, accesses to higher generations are sufficiently rare not to benefit from caching.</p><p>To test this hypothesis, we built an operating system with a Scheme interpreter in kernel mode, where the interpreter controls the cache. Generic x86 PC hardware was used, since it allows fine-grained control of cache decisions.</p><p>Measurements of execution time in this interpreter show that disabling the cache for generations higher than the first does not give any performance gain, but rather a performance loss of up to 50%.</p><p>We conclude that this interpreter design is not an improvement, but cannot conclude that the hypothesis is false in general. We suggest building a better CPU simulator to gather more data from which to make better caching decisions, moving internal interpreter data structures into the garbage collected heap and modifying the hardware to allow control in the currently rigid dimension of where data is cached---for example separate control of instruction and data caches and separate data caches for different areas of memory.</p>

A suggestion on uniform sludge and waste handling in the Baltic Sea AreaEklund, Per, Dahlberg, Stefan January 2010 (has links)
<p>The purpose of this thesis is to make a thorough but compact description of the international laws concerning solid garbage generated by vessels and sludge treatment. It is also to construct a pamphlet that can be used as a guide by ports when constructing their own information sheets to the vessels. The questions given to us from Baltic Master II were: what does the international legislation state about waste handling from vessels and in the port facilities, both sludge and solid garbage? Describe routines for receiving sludge, with concern taken to the rules that apply today. Describe routines for receiving sorted garbage and recycling, with concern taken to the rules that apply today. Look at the present symbols and labelling and develop a standard for vessels and port facilities. To solve these questions we choose an investigative method based on a literature study. The research of earlier studies showed that the parties involved consider the waste- and sludgetreatment to be flawed. In some cases the problems are fictitious or exaggerated. The main problem originates from the fact that there are no uniform routines for the interaction between vessel and port. Although there is more then one way to deal with this problem, we have concluded that the best way to improve the present day situation is to implement uniform routines. To make the routines effective they should be developed and agreed upon by the parties involved taking into consideration present day international legislation. In this thesis we present a suggestion on such a routine.</p>

"Alla mysiga var de bumbibjörnarna" : Some Early Swedish Learners' Reading Strategies in EnglishBolin, Elin January 2009 (has links)
<p>Being a skilled reader makes it easier to learn a new language. It is important to teach students how the knowledge and use of reading strategies can facilitate learning. This study was made in a Swedish fourth grade class with eighteen participant pupils. They were asked to translate two texts from English into Swedish: one was a poem with nonsense words, and the other a prose text. The texts were taken from <em>Through the Looking Glass</em> by Lewis Carroll and <em>The Garbage King</em> by Elizabeth Laird. After this an interview was made with all of the pupils in pairs, where they were asked about their reading strategies normally and in this situation. The results found were that the reading strategies used were: <em>likeness with their native language</em>, <em>previous vocabulary knowledge of the L2</em>, <em>syntactic knowledge</em>,<em> </em>and<em> guessing the meaning through the context</em>. The result confirms previous research in that the pupils who liked reading and did so in their spare time, did better when it came to making syntactically correct translations.</p>

Sophantering : En studie om integrering mellan fartyg, hamn och kommunRoysson, Anna, Lundgren Lindberg, Moa January 2008 (has links)
Vi ville, i och med denna uppsats, ge en beskrivning av de problem och konflikter som kan uppstå mellan fartyg, hamn och kommun gällande deras källsorteringssystem då tydliga regler för detta saknas. Studien utfördes med syftet att beskriva problemen utifrån de olika aktörernas perspektiv. Metoden som vi använde oss av var en kvalitativ studie med ett antal halvstrukturerade intervjuer. Vi valde denna metod eftersom den lämpar sig bäst för det valda ämnet då det inte finns mycket litteratur att stödja sig på. Resultatet vi kom fram till visade sig vara som väntat, ett befintligt problem som alla de inblandade aktörerna upplevt. Det som överraskade oss mest var att problemen hade en betydligt större omfattning än vad vi trott från början. Det som alla aktörerna påpekade var att problemen med källsortering måste uppmärksammas och med tiden lösas på ett, för alla inblandade parter, smidigt sätt. / With this thesis, we would like to present the problems that might arise, for vessels, ports and municipalities, due to the fact that there are no rules regulating the interaction between vessels and shoreside garbage management. The problem will be described from the different participants’ point of view. The method used in this thesis, is based on a qualitative study where different interviews have been made. We elected this method because it is best suited for the purpose of the chosen subject. The result will mostly be based on material from interviews since there is only a limited amount of literature to refer to. Our result point to, as was expected, an existing problem. The extent of the problem was not clear to us in the beginning of the study, but as the process went along we quickly became aware of the proportions of the problem. All participants’ have pointed out the importance of drawing attention to the problem and hopefully finding a solution.

Selection and Implementation of an Optimal System to Handle Garbage in Kigali, RwandaKahigana, Innocent January 2011 (has links)
Reports from various institutions claim that garbage management in Rwanda has had diverse effects on both the natural environment and human society. Such claims prompted for an exploratory study to find out an optimal system to handle solid waste in Kigali City. The study considered a literature review and primary data from 400 randomly selected citizens. They were surveyed about their opinions on which system they perceived to be the optimal to handle garbage in Kigali City. The computer software Web-Hipre was used to analyze data on the three systems considered to handle solid waste in Rwanda: briquetting, composting, and incineration.The results indicate briquetting as the optimal alternative to handle solid waste from homesteads and workplaces of Kigali City. Briquetting considers production of solid fuels that may reduce destruction of forests for fuel. Other major reasons for briquetting, highlighted by respondents, include improved kitchen hygiene and sanitation and replacement of charcoal for a less dusty fuel. Economic factors governed surveyed participants to prioritise briquetting system to handle solid waste in Kigali. Composting may be considered for transforming organic materials into mulch to support farming activities in rural areas as well as gardening in the towns. However, a centralised incineration system is presently not suitable. The private sector has so far not fully been engaged in the transformation of solid waste into bioenergy in Rwanda.
