The purpose of this paper is to standardize and simplify the design work on a few specific types of storage brackets for balconies. The company Balco AB had the wish to simplify the design work in the preparation of attachments to their balcony structures. This would be done by a calculation matrix that could be produced which then in turn could be used for each new project by the company. The design work behind the development of these fittings at each new project is costly both in terms of time devoted by each calculation but also the cost of the time. The purpose of this report is that in a systematic manner, a calculation matrix can be created that then the company instead may follow from each new project.In carrying out the project used HILTI calculation program, which was provided by the company HILTI.

This report describes how we made a dynamic website combined with staticalweb pages and a web shop for the Swedish company Tyger & Ting.The employer Tyger & Ting wish to run a working web shop on their site butthey want to keep their old system of updating pages with their old applicationfrom Intellyweb1, which creates statical HTML pages.The goal of this exam paper has been to learn to create a functional web shopwith user friendly layout and appealing design and also to take orders andfulfill wishes from a real employer.The report is describing how Intellyweb?s application and its statical web pageshas been implemented on a dynamic web page. The report does also describehow this site has been build and how the problems with the coding have beensolved. The coding has been made with HTML, PHP and MySQL. CSS hasalso been used.

Distillers? grain is a by-product of ethanol production. Corn, wheat and barley are the grains that are generally used in the distillery process. Distillers? grain is rich in protein and phosphorus.

The high level of energy consumption that the industrialised countries have reached and thepollution that this brings has long been a cause for analysis and debate, development and usageof so called renewable energy sources is therefore more important than ever. The energy in theelectromagnetic radiation from the sun is an interesting alternative. One way of harvesting thisenergy is by using solar cells, devices that generate DC current when exposed to electromagneticradiation.The goal of this master?s thesis was to design a solar powered power supply to Syntronic AB?sMidrange platform. The envisioned application is a stand-alone distributed embedded system,for example a node-based temperature monitoring system.

Biogas är en förnyelsebar energikälla som tillverkas genom att organiskt material som matavfall bryts ner av mikroorganismer under anaeroba (syrefria) förhållanden. Regeringen har satt upp mål för en högre matavfallsutsortering vilket leder till ökad mängd tillgängligt substrat till biogasproduktion.Matavfallet som samlas in börjar brytas ner under tiden det transporteras och lagras. Syftet med studien var att undersöka hur länge matavfall lagras, ta fram ett representativt recept på ett genomsnittligt matavfall i Sverige och utvärdera hur mycket metanpotential som försvinner från matavfall med avseende på lagringstid, insamlingssystem (papper- och plastpåse) och lagringstemperatur (22°C och 6°C) genom laboratorieförsök.Den genomsnittliga lagringstiden för matavfall från villor och flerbostadshus i undersökningen var sex dagar. Ett recept för matavfall har tagits fram med hjälp av litteratursökning och modifiering av recept i Avfall Sveriges rapport U2010:10. Laboratorieförsöken visade att skillnaden i metanpotential mellan plast och papper var tydlig vid 22°C, då metanpotentialen sjunker, men obefintlig vid 6°C.För att uppnå maximal metangasproduktion från matavfall under den varma delen av året så är plastpåsar bättre då de har en mer konserverande effekt på matavfallet än papperspåsar.

During the past few years a vast amount of research has been done to increase the understanding of the complex ecosystem of the Baltic Sea. Modelling and simulations are important tools to increase knowledge of the system. A suitable model must be simple to use and the parameters and variables needed in the model must be easy to access.In this paper a dynamical mass-balance model, CoastMab, which is validated for smaller coastal areas, has been used to predict concentrations and transports of phosphorus in three large coastal areas - the Gulf of Finland, the Gulf of Gdansk and the Gulf of Riga. CoastMab uses ordinary differential equations to regulate inflow, outflow and internal flows. To reflect seasonal variations in temperature and different types of flows the model has a temporal resolution of a month.

Clustered Columnstore Indexes (CCI) and In-Memory Online Transaction Processing (OLTP) are two new techniques that were introduced with Microsoft?s new database management system SQL Server 2014.The thesis analyzes these two techniques, describes the theory behind them and also the background information that needs to be known to understand more of the new techniques. Performance tests of the new techniques have been performed to see how much faster response time we can get and less storage we need to use where the result is represented by performance diagrams and a compression diagram. This thesis is a cooperative work with a company called Trimma and the result is used as support to decide if these new techniques could be of advantage for the company.The test consists of five test queries with different purposes. The result is illustrated by diagrams that show the result and another diagram that shows how much the data gets compressed with the different techniques.

Webbapplikationers komplexitet och mängden avancerade tjänster ökar. Loggning av aktiviteter kan öka förståelsen över användares beteenden och behov, men används i för stor mängd utan relevant information. Mer avancerade system medför ökade krav för prestandan och loggning blir än mer krävande för systemen. Det finns behov av smartare system, utveckling inom tekniker för prestandaförbättringar och tekniker för datainsamling. Arbetet kommer undersöka hur svarstider påverkas vid loggning av serverdata, enligt datainsamlingsfasen i web usage mining, beroende på lagringsstrategier.

Detta examensarbete har genomförts vid Mälarenergi Elnät AB i Västerås. Undersökningen föranleddes av regeringsbeslutet om att elmätare måste avläsas en gång per månad från 2009. Konsekvensen för Mälarenergi är att de måste investera i ett automatiskt mätinsamlingssystem. Syftet med projektet har varit att skapa en generell investeringsmodell för att ekonomiskt utvärdera ett antal mätinsamlingssystem. I rapporten har Milabs, Seneas, Enermets, HM Powers, Iprobes samt Techems och Viterras system analyserats.

The limit for mercury in fish, set by health authorities, is exceeded in about half of the lakes in Sweden. Methyl mercury (MeHg) is the most toxic form of mercury and accumulates in fish. Therefore transformation of inorganic mercury (Hg) to methylmercury (MeHg) is an important process that we need to understand in order to possibly counteract the negative effects of mercury in the environment. The seasonal dynamics of mercury biogeochemistry is likely of great importance for the accumulation of MeHg in the aquatic food web. In thesis the chemical speciation and transformations of Hg and MeHg in bottom waters and sediments is followed in Ängessjön, a small lake located on the east coast in the middle of Sweden. The lake is not directly affected by any industrial pollution and concentrations of Hg in the sediment reflect the atmospheric deposition in this area, as well as processes taking place along the hydrological pathways from soil to lake. Samples from sediment, bottom- and streamwater were collected in average every second month during the period Feb.

Platelet transfusions can be necessary during treatment of patients with thrombocytopenia or impaired platelet function. Platelet function in platelet concentrates (PC) deteriorate with storage time. Studying swirling is often used to control the quality of PC?s before transfusion but the method has some disadvantages. Therefore other methods can be useful, for example impedance aggregometry (IA, Multiplate® Analyzer) to measure platelet function.     In this study the change in platelet function over time was examined in buffy coat and apheresis platelets with IA where aggregation had been induced with adenosine diphosphate (ADP) and collagen.

As a result of my fascination for nature I have chosen to study the possibilities to introduce natural environments on schoolyards. Too many schoolyards are lacking vegetation and many of them look like sterile asphalt deserts. The master thesis consists of two parts. The first part is based on literature studies and the second part in which findings from part one are put into practice. Five examples are presented; four schoolyards in Malmö; Kryddgårdsskolan, Kirsebergsskolan, Rörsjöskolan and Lindängeskolan and one in Kalmar; Åbyskolan. Malmö Naturskola has been working with the chosen areas on the schoolyards in Malmö.

The need for a more efficient electrical grid has made the smart grid concept popular in recent years. The aims of this study are to identify the conditions in Sweden for implementing a smart grid and to analyse the opinions of stakeholders. One finding is that the large capacity of Sweden?s existing electrical grid decreases the immediate need for smart grid solutions. However, the rapid increase in wind power might push the development of a smart grid in the coming years.

This study investigates how nutrients from source-separated human urine from Gothenburg properties can be used as fertiliser in agriculture or for parks or sports fields. The initiator is the Department of Sustainable Water and Waste Management at the City of Gothenburg. Today urine-diverting systems are installed in two apartment buildings and two public-use buildings. Urine recycling is expected to lead to less exploitation of natural resources and less eutrophicating discharges into water recipients. In the study the urine?s market potential is investigated, for which practical handling issues, business aspects and acceptance of customers, employees and visitors have proved to be important.

In the process of making carton boards into Skoghall Mill, are great quantities of water being contaminated. This water has to be treated before it is possible to release into the recipient, Kattfjorden. One of the contaminations that is important to extract from the wastewater, is organic carbon (measured as TOC-total organic carbon) because microbiological breakdown can lead to the bottom becomig free of oxygen.The wastewater treatment at Skoghall Mill is done through an external wastewater treatment that is located at the factory. The biological treatment (aerated lagoon) is a 140 000 m3 water pool with surface aerator, which is give oxygen to the water. In the lagoon live microorganisms who performs the biggest part of the TOC-reduction.One problem with the lagoon is that the treatment of TOC is considerably worse during wintertime than during summertime.
