Arkitekturer i operativsystem : en fallstudie i monolitisk och micro kernel

Den tekniska utvecklingen driver fram allt mer avancerade datorsystem. Samtidigt ställs allt större krav på stabilitet och flexibilitet i de operativsystem som ska användas på dessa system. De senaste årtiondena har Micro kernel arkitekturen varit föremål för intensiv forskning och det finns idag ett flertal operativsystem på marknaden som använder denna arkitektur. Traditionella monolitiska operativsystem är relativt resurskrävande system som ofta anklagats för att sakna struktur. Micro kernel baserade system är en lösning på detta problem där man bantat ner kernel till så lite som ett tiotal kilobyte och flyttar ut tjänster som normalt ligger i kernel till user space.

Micro kernel baserade system är en lösning på detta problem där man bantat ner kernel till så lite som ett tiotal kilobyte och flyttar ut tjänster som normalt ligger i kernel till user space. Solaris och Linux bygger på en utveckling av monolitisk kernel där man byggt operativsystemet i ett antal sinsemellan beroende lager vilket bidrar till ökad struktur i systemet. Flexibilitet uppnås i dessa system genom att man lägger till funktionalitet för att under exekvering länka in ny kod i kernel. Windows NT och Mac OS X är baserade på Micro kernel arkitektur.

Ska pyramiderna rivas?: en studie om mikromakt

It has been demonstrated in this study how people working in frontline jobs in service organizations are exercising ?micro power?. The use of ?micro power? is defined as ?to in ones professional role, without objectively defensible reasons, impose sanctions on a customer?. The interviewees are explaining their use of ?micro power? with mood, working conditions, and customers? behavior.

Micro plastics in the oceans and their effect on the marine fauna

Small pieces of plastic, termed ?micro plastic? in the oceans derive mainly from degradation of big plastics such as beach littering, but also from sources of direct emission from e.g. beauty scrubbers and synthetic sand-blasting. These micro plastics are ingested by marine animals ? mistaking them for plankton ? or via prey.

HRM i Mikrotjänsteföretag

The purpose of this essay was to find out how leaders in micro service firms practice HRM and identify which HRM related problems they experience in their leadership. A case study consisting two cases was carried out. The study has shown that leaders in micro service firms use a highly personalised, informal management and involve their employees in the firm?s development. The findings were that leaders of micro service firms do not have any theoretical knowledge of HRM practises because of lack of education.

Kreditbedömningen av mikroföretag : Kreditbedömningens faktorer och påföljden av den slopade revisionsplikten

Introduction: 1 November 2010  came the amendment about the audit requirement into force. The amendment concerned only micro-enterprises. The most common form offinancing for micro-enterprises are bank loans, therefore the banks play a major role in the business and wellness of micro-enterprises.Purpose: Purpose of this paper is to examine if the credit assessment has been affected by the removal of the audit requirement for micro-enterprises.Method: This study will be conducted by a qualitative study in the form of interviews. Five interviews were conducted, with four respondents from the large banks and    one respondent from Almi Företagspartner.Conclusion: All respondents agreed that the audit is seen as a mark of quality, some lenders will continue to request it from the micro-enterprise while other lenders look at other factors such as ownership, relationship or business concept..

Support Vector Machines for Classification applied to Facial Expression Analysis and Remote Sensing

The subject of this thesis is the application of Support Vector Machines on two totally different applications, facial expressions recognition and remote sensing.The basic idea of kernel algorithms is to transpose input data in a higher dimensional space, the feature space, in which linear operations on the data can be processed more easily. These operations in the feature space can be expressed in terms of input data thanks to the kernel functions. Support Vector Machines is a classifier using this kernel method by computing, in the feature space and on basis of examples of the different classes, hyperplanes that separate the classes. The hyperplanes in the feature space correspond to non linear surfaces in the input space.Concerning facial expressions, the aim is to train and test a classifier able to recognise, on basis of some pictures of faces, which emotion (among these six ones: anger, disgust, fear, joy, sad, and surprise) that is expressed by the person in the picture. In this application, each picture has to be seen has a point in an N-dimensional space where N is the number of pixels in the image.The second application is the detection of camouflage nets hidden in vegetation using a hyperspectral image taken by an aircraft.

Standardiserad systemlösning för mikroföretag

The thesis is about exploring possibilities for developing a standardised system solution for micro businesses, this since most of the micro business lack proper system solutions, a contributing factor of this is price and also incompatibility between the solution and the business itself. The system solutions we will refer to are solutions which task is to cover the most important needs that a micro business might have on their system. The main goal with this research is to see if this is possible, and if so, how the developers should think to take it further. We chose to do this by identifying the most significant of needs a micro business has when it comes to this type of system solution.In this thesis we will present three needs which were evaluated and brought forth through the analyses of various interviews and observations we had done during the study. The interviews took place at respective company with their employees and consisted both closed and open questions with our main focus on the open questions because we wanted to obtain as much information from the respondents as possible from several viewpoints.

Utvärdering av micro-Devalvärden: för makadamballast för järnväg

Det huvudsakliga syftet med detta examensarbete har varit att utvärdera micro-Devalmetoden för att eventuellt fastställa ett kravvärde. I rapporten behandlas även hur LT-index och kornlängd förhåller sig till varandra samt om differentierade krav på Los Angeles-tal kan ställas beroende på olika axellaster. Examensarbetet har i huvudsak grundat sig på en litteraturstudie samt sammanställning av inkomna analysprotokoll via Banverket. Analysresultaten presenteras i form tabeller och diagram. Rapporten har mynnat ut i en slutsats där författarna anser att ett krav på kategori MDERB 7 är lämpligt.

Män som mikroföretagare : Hur beskriver de balansen mellan arbete och övrigt liv?

The aim of this study was to explore how six men who run a micro-enterprisewith a maximum of 10 employees handle the balance between work and otherlife. Qualitative approach with semi-structured interviews was conducted and thesample consisted of six men with micro-enterprises of varying ages. The themesused in the interviews were boundless work, roles, boundaries strategies anddemand / control - social support. The results showed that micro- entrepreneursdo not experience any major imbalance between work and other life. The studyrevealed that the division of roles in the home of the elderly respondents was ofthe classical gender character that woman took great responsibility in the home.Among the younger respondents the unpaid work at home was equal divided.Social support was perceived highly by all respondents, and they alsoexperienced a high level of control over the requirements of the job.

Migration of a very large database with Swedish demographic data, using Microsoft SQL Server

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

Karaktärisering av höstvetets avkastningskomponenter

Wheat yield depends on the number of ears per m2, the number of kernels per ear and the kernel weight. By knowing the ability of different cultivars to compensate for the different yield components and knowing which yield component that is the most important for the final yield, the farmer can match the cultivar and management to the location. The objective of the study was to investigate how the yield components of winter wheat vary depending on genotype, environment, sowing density and date of sowing.Seven varieties were grown in four locations in Sweden with three different sowing densities and with an early and a late sowing date. On each experimental site, the surviving plants after winter were counted, as well as the number of shoots at early and late spring and the number of ears. Ten ears from each site were cut at three different occasions, starting from the time of blooming, with 200 day degrees between each cut.

Förenklad revision av mikroföretag? : En kvalitativ studie sedd ur fyra revisorers perspektiv

Background: Sweden has, since 1983, had a statutory audit for all joint-stock companies. However, according to EG?s fourth corporation directive, member countries can decide on their own if this applies for small joint-stock companies. An investigation was launched in the fall of 2006 to form an opinion on the importance of the audit reporting by law and what an abolishment of this rule would mean for small joint-stock companies. Critics are claiming that the cost of audit for small companies is exceeding the cause in these micro companies.Audit is regulated by Swedish translation (RS) of International Standards on Auditing (ISA) and is to be applied in all companies comprised by the statutory audit.

Minivindkraftverks inverkan på lågspänningsnät

Micro-power wind energy convertors have recently increased in popularity. The reasons for this are among other things the increasing cost of electric energy and enviromental concern.In this thesis the connection of these micro-power wind energy convertors to the utility network is discussed.
