Fällning av kisel från avloppsvatten vid Hellisheidarvirkjun - experimentell studie

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica Scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica Scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica Scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

Matematik, ett tråkigt ämne! Kan laborativt/praktiskt arbetssätt ändra elevers attityder till matematik?

The aim of the study was to investigate the students´ attitudes towards mathematics, their knowledge in the subject area they find the least interesting and whether laborative/practical working methods could awaken their interest and curiosity. During our work, we have looked into previous studies regarding girls´ and boys´ attitude and performance in mathematics. We handed out surveys to students in grade 9 at a School with many people from other cultures and nationalities in Malmö in order to find the answers to our questions. The result showed that most of the students thought that the subject area "Scaling" was the least interesting. The implemented action program was a laborative/practical task within the "Scaling" area.

Frekvens och spanningsskalning i en inbyggd mikroprocessor; for att mojliggora implementationen av schemalaggning med stod for dynamisk frekvens- och spanningsreglering for energihantering.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency Scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage Scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency Scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency Scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

Användarorienterad förarsituation för bergavläsning vid fjärrstyrt skrotningsarbete

Mechanical Scaling is one of the most complex operations of all in the mining process. The operators are using both hearing, sight and feel to read the rock and to know where to scale and where to leave. They say they go on gut feeling in great extent, something that comes with experience. The Scaling machine is placed into the edge of unsecured and newly blasted rock to hammer off the blocks that has become loose after the blast, but not enough to fall down. It goes without sayingthat it is a risky job.

Klinisk utvärdering av lokal antibiotikabehandling hos rökare i ett parodontalt stödbehandlingsprogram -en pilotstudie

Syfte: Syftet med den här pilotstudien är att undersöka om lokal antibiotikagel, 8,8 % doxycyklin, som tilläggsbehandling kan förbättra läkningen av inflammerade tandköttsfickor hos vuxna rökande patienter under stödbehandling. Material och metod: I den här dubbel-blinda randomiserade kontrollerade pilotstudien valdes 20 vuxna rökande patienter ut från ett parodontalt stödbehandlingsprogram. Patienterna indelades i två grupper, 10 i testgruppen (doxycyklingel 8,8 %) och 10 i kontrollgruppen (placebogel). Vid baseline och tre månader efter behandling utfördes parodontal klinisk registrering. Patienterna fick behandling med Scaling och debridering i hela bettet, testgruppen fick applicering av doxycyklingel vid testtänder (PPD ? 5 millimeter, BOP) och kontrollgruppen fick placebogel applicerad vid kontrolltänder (PPD ? 5 millimeter, BOP).

Tjänligt vatten i kranen - Membranteknik gör det möjligt : En utredning av pilotförsök i Glemmingebro

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

Interactive Visualization of Statistical Data using Multidimensional Scaling Techniques

This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.

Utveckling av differentierade transportersättningar för rundvirskestransporter med lastbil

Approximately 60 million cubic meters of round wood are transported every year with trucks in Sweden and stand for 15 % of all truck transportation in the country. The big amount that is transported results in many haulage companies works in different parts of the country with different conditions to get a good flow on their transports. Today the transport pricing is very general and the payment consists of the unit round wood they are transporting and the distance of the transport. The purpose of this study were, from the freighter and the haulage company?s perspective, try to find ways to change the today applied transport pricing to more differentiated and compare them to historic payment of transportation.

Undersökning av energibesparande metoder för multiplikator

In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are introduced in the circuit and are then evaluated. The conclusions are that all investigated methods, pipelining, interleaving and voltage Scaling, should be maximally made use of in order to minimize the power consumption..

Uppföljning och analys av Stockholms stads solcellsanläggningar

During 2007 the City of Stockholm installed five grid connected photovoltaic systems. The aim of this master thesis is to quantify the amount of produced energy and recommend routines to collect and analyse production data, to make production data accessible by the public and to gain experience for future installations.The total amount of produced energy until March 2009 is 227 000 kWh, with an annual rate of 150 000 kWh. The expected annual rate was 148 000 kWh.All system owners are positive about their plants and see economical benefits in Scaling up such systems.The installations need very little attendance and maintenance, however it is recommended that an alarm function is installed for automatic feedback in case of a system failure. All future systems should be inspected during full operation to determine if the actual capacity is matching the installed capacity..

Scalable Services over DAB and DVB-T from a Receiver Point of View

TV and radio services have always been distributed over analogue broadcasting networks and been received on a TV -set or a radio receiver. Today this situation is changing due to digitalization and convergence between broadcasting, telecommunications and data communications. Other terminals, such as a PC, can also receive TV and radio services. Digital TV and radio can offer additional services such as e-commerce, electronic program guides and content synchronized to the TV and radio shows. If these services are to be received by several receiving terminals with different properties, the services must be adapted to the terminals.
