Detta examensarbete kommer att gestalta en ny infart på ett kommande bostadsområde i centrala Piteå. Bostadsområdet heter Vargen 30 och i det ligger idag behandlingsenheten Strömgården samt öppna parkeringar och garage till närboende. Ombyggnationerna kommer även att påverka äldreboendet Österbo vilket kommer att framgå i rapporten. Gestaltningen gör jag med underlag från fysisk planering på Piteå kommun, där Kenneth Sjödin visar den vision som de har utifrån det förutsättningar som finns. Förutsättningar innebär viss mån av inskränkningar i planeringen, som jag måste ta hänsyn till. Befintliga byggnader, fordonstransporter etc., måste tas i beräkning. Examensarbetet bygger på ett verkligt projekt, från vision till färdiga bygghandlingar där flera olika alternativ har tagits fram, samt motivering till varför det blev just det förslaget som valdes. Projekteringen innebar arbete med underlag från Piteå kommun där jag fick anpassa projektet till Norconsults riktlinjer vad gäller standarder och former. Kontakt hölls kontinuerligt med ansvarig på Piteå kommun som beslutade hur området skulle planläggas. Arbetsgången har utförligt beskrivits i rapportdelen med bilder samt med mina egna tankegångar rörande den nya infarten. Kommunen antog mitt förslag och byggnationerna förväntas starta sommaren 2019.

Skellefteå Kraft has had high CO emissions problems in a bubbling fluidized bed (BFB) boiler in Malå.Statistical emissions data from 2013 to 2019 shows plant average emissions of 1230 ppm. Thisexceeds the recommended 440 ppm (6 % O2) that Naturvårdsverket proposes (Naturvårdsverket,2005). The aim of this project was to identify and map the cause of the BFB boilers high CO yield withthe help of a literature study as well as practical experiments to reduce CO, and; furthermore,suggest possible changes that can be implemented to resolve this problem.A literature study was conducted to gain a better understanding of possible causes of high CO influidized bed combustion of biomass. The results from the literature study showed that bedagglomeration, airflow symmetry, biomass moisture content, biomass particle size and biomass beddistribution all are common factors that can cause high CO emissions.Based on the literature study, statistical data from 2013 – 2019 and employee operator experience aseries of tests, calibrations and experiments were conducted on the boiler. The following methodswere used; Boiler statistical data analysis; Primary, secondary and tertiary airflow mapping;Pneumatic boiler feed system test (biomass bed distribution) and a bed material change test.From the statistical data analysis, it was found that sudden load variations had a minor contributionto the CO emissions. However, load variations were not the biggest contributing factor to high COemissions in the boiler in Malå. The primary, secondary and tertiary airflow were measured andmapped, uneven airflows between left and right were found. By calibration of even air distribution inthe primary systems CO levels were slightly reduced by 14 %. The primary air calibration improvedleft to right boiler air distribution from a 5 % difference to only a 0.7 % difference.A series of 11 tests was conducted on the pneumatic boiler feed system to obtain optimal fueldistribution. The test series that consisted of maximum parameters for transport air, spreading airand casting air obtained the lowest CO emissions levels of 350 ppm. An increase in airflow oftransport air in the pneumatic boiler feed system resulted in more even biomass bed distribution andincreased airflow in the lower secondary zone. This resulted in a dramatic CO emission decrease by63 %. A 45 °C temperature increase was also noticed in the secondary zone, a decrease intemperature before super heater 2 and a decrease in temperature before super heater 1. The changein transport air caused combustion of flue gasses to occur a lot lower in the furnace.This was clearly also documented through visual images taken inside the boiler with a special camerawhile the boiler was in operation. The images taken inside the boiler before and after theadjustments clearly showed that an increase of lower secondary air moves combustion closer to theboiler bed and reduces the CO emissions. The images also showed that uneven combustion wasoccurring in the boiler, as more violent and turbulent combustion was occurring on the right side ofthe boiler. This was an interesting finding as the measured airflow distribution was even in the boiler.This suggests that there is a major leakage in the air distribution pipes on the left side of the boiler.By reducing the airflow to the right section and increasing airflow to maximum on the left, an evenairflow distribution was obtained resulting in a more even combustion throughout the entire boiler.An increase in bed material change frequency from 1 time (3 % regeneration of total bed mass) to 3times (9 % regeneration of total bed mass) resulted in a CO emission decrease by 20 %. During thebed material change test bed agglomerates were observed which may explain the possible emissionsimprovement as the bed material was changed more frequently.All different tests were conducted independently of each other. The change that resulted in thehighest CO reduction was the increase of transport air to the secondary zone. Emissions werereduced by a total of 68 % as the transport air was set to maximum flow, the sand was changed threetimes and the primary airflow from left to right was even. The proposed adjustments will likely alsoincrease the boiler efficiency and reduce the maintenance of super heater 1, super heater 2 as wellas the economizer. The boiler produces around 400 ppm at 6 % O2 after the changes have beenimplemented. This is significantly lower compared to the original operation settings that during 2013to February 2019 have produced a CO emission of 1230 ppm (on average). The significant COdecrease in Skellefteå Kraft’s boiler has opened opportunity to operate the boiler with lower excessair which ultimately decreases exhaust heat losses. If Skellefteå Kraft were to succeed in operatingthe boiler at 3 % O2 excess, a sum of 255 kkr could be saved annually.The following recommendations are given in order to achieve low CO emissions:- Increase the bed material change frequency.- Clean pneumatic airflow system during summer stop annually.- Ensure airflow symmetry within the boiler is achieved annually.- Increase airflow to lower secondary zone.- Use recommended airflows for pneumatic boiler feed system.- Invest in a buffer tank to reduce load variation by Setra Sawmill.- Reduce secondary air nozzle size to increase combustion air in the middle of the boiler.- Increase the feed port ramp angle to increase biomass casting length in the boiler.- Investigate left side secondary air flow (possible leakage suggested)

There seems to be enough information available on how different types of radiation may affect human health. There also seems to be adequate research made about NORM and how to handle this phenomenon. The image put forth by this study shows that the appearance of NORM within affected industries do not appear surprising or difficult to deal with. On the contrary it seems to be a well-known issue and safety measures have been adapted accordingly. It appears as if these issues have been overlooked regarding the systems where LNG is being used as a marine fuel. There is not enough data to conclude whether NORM is an issue or not in such systems.

The continuous strive for improvement and achieving higher efficiency for the ability to keep up with the market, as the competitors increases with the newer technologies that becomes available for the world leading companies. Project performance approaches as an aid towards project success is thus an important topic among organizations as a subpart for increasing their project planning efficiency. This case study is performed at a company within the industrial manufacturing where the profits has been decaying for decades. The efficiency regarding project planning has been heavily reduced. Evaluate and estimate the performance measurement effects caused by the current planning tool compared with another major planning tool used world-wide by a vast majority for project activity scheduling. The goal is to evaluate the differences a change-up can do in the three variables such as cost, time and quality but this study brings an additional variable –client satisfaction –that has an effect on the total project efficiency, and if a change-up could be necessary for the project managements. This has been done by collecting data in forms of interviews with people from different areas involved in the project planning process and people with who have experience in using two different major planning tools. The data were then analyzed and comparisons between the planning tools were made. The final part of the master thesis concludes the results of the research question and hypothesizes and that these were significant to the study as it reaches its purpose with additional variables such as communication, visualization and client satisfaction.

This thesis explains how a simple parental control can be developed. The system aims to limit kids’ activities rather than entirely restrict those activities. However, current solutions are applying some filtering methods that prevent kids from playing games. In order to overcome this issue, this thesis presents a simple approach to implement a cost-effective parental control using low-cost hardware devices and open source applications.The main advantage of the suggested method is that it can be used without installing any additional software and gives parents general information about their kids' activities on the internet without preventing kids from playing online games.
