Generationsskräpsamling med explicit kontroll av hårdvarucache

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.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.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.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%.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..

Det individuella samlandet : från längtan till begär

This essay deals with the individual collecting of four individuals with different backgrounds and lives. The essay investigates what, how and why people collect. It provides a stepping-stone in moving closer to understanding one, in human nature, deeply rooted phenomenon - collecting.The essay is based on a list of questions made by the Nordic Museum in Stockholm. It also includes in-depth examinations of four person?s passion of collecting, in which four individuals were interviewed: a pig collector, a collector of Mickey Mouse items, a multi-collector of objects from other cultures and one collector of items related to the artist Madonna.

Making Money in a Dirty Business

Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters. The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.

Konstsamlares agerande

Until recently, the art market has expanded for several consecutive years. The primary art market is characterized by an unclear pricing mechanism and an infinite as well as limited supply. Previous business studies have so far primarily focused either on art as an investment or on the gallery?s activities. This thesis takes an explorative approach and aims to shed a light on the art collector?s behavior on the Swedish market for contemporary art.

Elektroniskt kungörande av författningar ? en IT-politisk lösning ur ett användarperspektiv

This essay analyses the arguments of The Swedish Government Official Report 2008:88 which proposes that the Swedish law (SFS) should shift from promulgation in print to elec-tronic promulgation on a Website. I have studied two aspects of the arguments in the text. On the one hand, the Inquiry?s description of how things might become if their proposal becomes effectuated and, on the other hand, how the present situation is described in the text. The theory I have used is called A Garbage Can Model of Organizational Choice, which pictures organizations as often irrational in dealing with problems, solutions and decision making.

Målgruppsanpassad sopsorteringsinformation till nysvenska hyresgäster i Eskilstuna

In this thesis I have investigated four housing corporation?s information about garbage disposal for their tenants (primarily immigrants who just arrived to Sweden).   Interviews with renters, employees of the housing corporations and employees of Eskilstuna Energi och Miljö indicates that the garbage information need to be improved to be better adapted to the target group.    To solve this information problem I decided to create an information chart, consisting of illustrations and legible text which informs the renters of how and, above all why it is important to recycle.   The aim of the project is also to increase the renters? commitment and motivation in recycling and also; make the housing corporations, other organizations and authorities aware of how important it is to adapt information to different kind of groups. The aim in Information Design is always to work from the needs of the recipients..

Exekveringsmiljö för Plex-C på JVM

The Ericsson AXE-based systems are programmed using an internally developed language called Plex-C. Plex-C is normally compiled to execute on an Ericsson internal processor architecture. A transition to standard processors is currently in progress. This makes it interesting to examine if Plex-C can be compiled to execute on the JVM, which would make it processor independent. The purpose of the thesis is to examine if parts of the run-time environment of Plex-C can be translated to Java and if this can be done so that sufficient performance is obtained.

Flöden över Öresund En studie av beslutsprocessen som ledde fram till ett samarbete mellan Lunds och Frederiksbergs kommun

Denna uppsats söker förstå beslutsprocessen som resulterade i att Lunds och Frederiksbergs kommun fattade beslutet om att samarbeta. Beslutsprocessen resulterade i ett informellt samarbete, och söks förstås med hjälp av Cohen, March och Olsens Garbage Can-modell, och Kingdons window of opportuntity (möjlighetsfönster). Garbage Can-modellen består av fyra flöden, som innehåller beslutstillfällen, problem, lösningar och deltagare. Dessa flöden kan kopplas samman då möjlighetsfönster uppstår, vilket sker vid opinions- eller känsloförändringar bland befolkning och politiker.Vi har kommit fram till att beslutsprocessen bör förstås som att lösningen informellt samarbete mellan Lund och Frederiksberg, kopplades till problem relaterade till att vilja vara en del av Öresundsregionen, och beslutstillfällen såsom Öresundskommittén. Deltagare drev lösningarna och identifierade problemen.

Fjärrstyrd undervattensfarkost

Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
