Adaptive QoS Management in Dynamically Reconfigurable Real-Time Databases

During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-Time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.

Axial- och gradientkrympning hos golv på mark enligt Eurokod 2 : Sprickbredders beroende av betongkvalité, tvångseffekter och armeringshalt

AbstractConcrete foundation slabs are usually exposed to unilateral drying during the curing process. The unilateral drying causes an axial shrinkage and a concave curvature of the construction. The curvature results from the fact that the upper part of the slab is drying and shrinking faster than the lower part. This is called gradient shrinkage.A problem occurs when the slab is considered fully restrained by adjoining structural parts. The deformations caused by axial contraction due to the constant part of the shrinkage and the curvature caused by gradient shrinkage of the slab are then prevented by the fact that the slab is fully restrained.

Utvärdering av substrat för biogasproduktion

The purpose of this study was to evaluate the different substrates that enter the digestion on Sundet wastewater treatment plant for production of biogas.This work have done an analysis of data about the biogasproduction from January 2012 to feburari 2013, this showed that the food substrates has a greater gas production than internal sludge.Through laboratory test the VS, TS and COD values for all the substrates used in the biogas production could be determinded. But the COD-method was less optimal for analysis of fat and food, therefore it optimized the method for fat but due to Time constraints, this could not be done on the food substrates..

Möjligheter och begränsningar med läroboksbaserad och laborativ matematikundervisning

Mathematics is a central topic in today's education debate, including discussion of its educational quality and various teaching methods. Today basically two different teaching methods are used; one is the textbook based method, with the book in focus and the other one the laboratory method by which teaching is performed through practical applications. The purpose of this study was to examine four primary school teachers' view of these two teaching methods by means of four relevant inquiries. By interviewing the four teachers, advantages and disadvantages were highlighted and the purpose was achieved. In order to support the analysis, two theories applied; the socio-cultural perspective and the cognitive perspective.

Kvalitetschefens Roll och Kompetens Inom Svenska Organisationer och Företag

The role of the quality manager has evolved from being a quality controller to work with a more global business. Within many organizations in Sweden, however, the traditional role of the quality manager's remains and the tasks categorized as quality control still takes up most of the quality manager's time. The survey conducted as part of this master thesis shows that the quality manager in most businesses has multiple roles in addition to the role of quality manager, which can create a role conflict. One consequence of this is that each improvement is not given priority due to Time constraints. Although the importance of a clear and committed leadership is the key for succeeding as the quality manager.

Webbaserad schemaläggning av läkare : Systembeskrivning och gränssnittsförslag

Through analysis of the work of scheduling the doctors at the hospitals of Sundsvall,Gävle and Karolinska in Stockholm this thesis presents some conclusion about howand why a computer system would benefit these very tasks. The reason for doing thisis mainly to save money through more efficient scheduling, but also to minimizeerrors and maximize comfort for scheduler and doctor alike.Scheduling consists of collecting doctors? requests, assessing the need of staff,distribute the available doctors and make sure all tasks are covered throughout thescheduled period of time. The work is often very complex and involves manyvariables ranging from competence to personal whishes and economical constraints.Solving these problems takes a lot of time and energy which could be better spentcuring patients.The conclusion of this thesis is that there is reason to develop such a system to savetime and optimize resources. A description of the system is found in numerous lists ofroles, tasks and prototype sketches which combined shape the content andfunctionality.

Ställtidsreduktion i montering av kopplingar

VBG Produkter AB is a process-orientated company that develops, manufactures and markets trailer couplings with belonging coupling equipment, protection equipment against skidding and stands for wagon-bridge for heavy vehicles. The company feels that their set-up time in production for couplings is not at an acceptable level. Due to high demands of customer oriented production the intermediate stock level of included products within the assembly of couplings has gradually increased which has resulted in high inventory holding costs. VBG Produkter applies Kanban in their production, therefore it is important to produce exactly the necessary amount and avoid overproduction. The objective of this project is to suggest appropriate solutions so that VBG Produkter is able to reduce their set-up time in assembly of couplings, by identifying internal and external set-up time for the chosen process bushing cell.

As a complement Lean-inspired tools are used.After compiling the results from the interviews and benchmarking somesuggestions are made. These are reviewed with stakeholders and a discussion ofhow to go on further was held.

Modellering av manövercylindern för Nosstället på JAS39 Gripen

When models are used to describe physical phenomenon during development or modification of a technical system, it is often possible to reduce both the time needed and the overall development cost. With the use of models it is also possible to investigate the potential of the selected solution, without the need for any expensive details and testrigs. In many cases it is also not possible to test all the aspects regarding the functionality that are desired from the system, without using the complete and final product.In this case a model based approach has been used to optimize the different parameters in the new snubbing mechanism for the Nose Landing Gear Retract Actuator on the JAS39 Gripen.During the simulations, upper and lower boundaries were calculated for the length of the spring and the diameter for the restrictor. The governing constraints were given by the requirements for the retraction time during cold conditions and that the amplitude of the alternating loads in the uplock mechanism were brought to an acceptable level.The most promising results from the simulations were then used in a limited number of trials in the hydraulic rig to verify that the configurations comply with the requirements.The final parameters for the snubbing mechanism were chosen to 35±1mm for the spring and 0.4-0.5 mm diameter for the restrictor..

Ingen ser mig ? finns jag? : En uppsats om exkluderade barn i leken

The aim of this study is to describe successful strategies to include children in free play activities at the preschool. The methods that pedagogues use to act and work with excluded children will be examined. To get answers to my questions I have conducted interviews with five pedagogues in four preschools. During interviews they mention two different approaches to encourage free play activity. One way was to participate and play along with the children.

Netspeak som retoriskt verktyg : Skapar elementen inom netspeak mer påträngande problem än vad de löser?

With inspiration from Bitzers situational analysis a phenomenografic method has been used, influenced by Brown & Levinsons´s theory of politeness, to find perceptions concerning constraints (in Bitzer´s sense in his model of the rhetorical situation) in Internet-based communication. Based on three qualitative interviews, this essay has found that the perceptions are closely linked to views of what constitutes formal and informal contexts, varying due to the gender or age of the informant. Netspeak is not considered appropriate, with some exceptions, in any formal situation. However, the perceptions regarding decorum in informal situations differ in nature, based mainly on what kinds of associations and connotations are produced by elements found in netspeak. Since perceptions regarding informal situations vary, there is a large risk of misunderstanding, which this essay aims to survey..
