The district heating load is seasonally dependent, with a low load during periods of high ambient temperature. Thermal energy storage (TES) has the potential to shift heating loads from winter to summer, thus reducing cost and environmental impact of District Heat production. In this study, a concept of high temperature borehole thermal energy storage (HT-BTES) together with a pellet heating plant for temperature boost, is presented and evaluated by its technical limitations, its ability to supply heat, its function within the district heating system, as well as its environmental impact and economic viability in Gothenburg, Sweden, a city with access to high quantities of waste heat.The concept has proven potentially environmentally friendly and potentially profitable if its design is balanced to achieve a good enough supply temperature from the HT-BTES. The size of the heat storage, the distance between boreholes and low borehole thermal resistance are key parameters to achieve high temperature. Profitability increases if a location with lower temperature demand, as well as risk of future shortage of supply, can be met.

Denna studie tacklar ett av de problem som modern IP-telefoni brottas med, som gör att det är svårare att konkurrera med traditionell telefoni: fördröjningar på grund av otillräckliga Session Initiation Protocol-servrar (SIP). Genom tester av de viktigaste faktorerna jämförs fyra högaktuella Open Source SIP-servrar: OpenSIPS, Kamailio, FreeSWITCH och Yate. Avsikten är att underlätta valet av SIP-server för nya applikationer inom IP-telefoni, öka prestandan samt snabba på utvecklingen. Studien behandlar de intressantaste faktorerna vid val SIP, såsom användarvänlighet, hastighet, lagring av användardata samt ljudkvalité. Slutsatsen blev att Kamailio stod som klar segrare, med överlägsna resultat i jämförelse med övriga servrar, på de parametrar som valts ut.

We also created an administrative system for the media player withPHP programming.The website contains a simple guestbook; the guestbook makes use of adatabase created with MySQL.Our work resulted in a webpage with a fully functional media player thatstreams audio files together with a corresponding administrative system for it..

To understand the motives, and perhaps more importantly the barriers, for farmers to convert from conventional to organic farming is of great interest for policy makers as well as for academics. In Sweden and in other EU countries, proposed targets of the area in organic farmland have failed to be reached in spite of different kinds of policy measures. Most studies agree that the average profitability seems to be comparable to or better in organic than in conventional farming. This would indicate that there must be other factors of importance which can explain the low particiapation rate. A higher perceived risk in organic farming with respect to yield and price is frequently brought up as a potential explanation within a qualitative framework.

This report describes the work with creating a CMS (Content Manager System). A CMS is a web tool so you easy can publish materials on your web page. With a CM Scan you can without any knowledge of programming web pages create and maintain a web page. This will result in that you and your organisation save time and money. You can also split the responsibility for the webpage in different roles, but still keep the control. We have chosen to create our CMS in a script language called php4 and with the database server MySQL, we have also used JavaScript a lot.

AbstractThis study aims to investigate the applicability of well-recognized supply chain strategies based on product characteristics. Choosing the right supply chain strategy can be the difference between winner and loser in today?s competitive climate and science offers several recommendations as to which aspects that should be considered. Fisher (1997) and Christopher and Towill (2002) suggest that supply chain strategies should be based on what kind of product the company is handling and that, in order to know which strategy is the most appropriate, the products must be categorized. Some criteria developed for the categorization are lead time, forecast in demand and profit margin.

The main objective with this study was to investigate so called odd purposes acceptable when registrating property along with how social development affects these purposes, furthermore to investigate how the cadastral surveyors estimates a foreseeable time. Tradition and praxis is used for several obvious purposes such as housing, farming, forests, offices and industry. Praxis is yet to be defined regarding more unique purposes. There is no mention in the law about which purposes are found acceptable to assure the demands on suitability are met. Cadastral authorities are responsible for making sure the division into property units is uniform and rule of law-accordingly.

Have you ever had problems sorting your cables, are the winders you use too big and crude then the EC-winder is the product for you. The EC-winder concept is a compact and intelligent winder for home application. Its simple design and subtle looks enables it to blend in with the surrounding environment. Its function is designed so that it with ease can be handled by any one after only a couple of instructions. You simply thread the cable trough the opening on the winder and then you rotate the upper part until the cable reaches the desired length. After use the winder can be opened to enable easy extraction of the cable..

This thesis aims to examine the differences in interpretation and application of the new legislation regarding the standardized parental deduction within the Social Insurance Code and the Act Concerning Support and Service for Persons with Certain Functional Impairments. The primary focus is on the differing perspectives of the Swedish Social Insurance Inspectorate (ISF) and the Swedish Social Insurance Agency (F?rs?kringskassan). ISF emphasizes the importance of referencing legislative preparatory works in interpreting the law and has criticized F?rs?kringskassan for failing to do so in its administrative practices.

This report describes the procedure in which we accomplished our task, which was to implement a present algorithm. This was made using C++. The algorithm is developed by Sasan Gooran, who is our examiner in this project. The algorithm uses an iterative method to produce the halftoned images. The reason for this project is to speed up the existing program which is made in Matlab.

The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.

The usage of location in mobile applications is becoming more explored as a field, but the ability to implement location-specific data has often been limited and the applications mainly focusing on having information location liked. This thesis aims to explore how to make a mobile application that lets users share and take part of each other?s memories. As well as finding an appropriate balance between location based and location linked messaging..

The purpose of this paper is to examine the law regarding gross violations of women and its application in the Swedish legal system. We have investigated how the legal system takes into account a holistic perspective of the vulnerable situation of women in the investigation and assessment and the extent to which psychological violence in the form of verbal abuse, threats and harassment attention. We also wanted to find out how the law's design may contribute to difficulties in the implementation and interpretation of it. In this study, we used a qualitative research approach when we decided to conduct an interview with a police officer and a textual analysis of four cases from the district court. Interview questions were semi-structured in order to gain a deeper understanding of the phenomenon.

Att fjärrstyra sin värmepump gör det möjligt att styra inomhusklimatet även då man inte är hemma. Detta passar mycket bra i exempelvis fritidshus då man enkelt kan höja temperaturen innan man skall dit och därmed kan njuta av ett behagligt inomhusklimat direkt.Med dagens fjärrstyrning av Daikins värmepumpar finns två problem. Systemet använder GSM-nätet och användaren måste kunna de olika SMS-koderna utantill. Fjärrstyrning används oftast i fritidshus på landsbygden och 3G-nätet har idag bättre täckning än GSM-nätet på många av dessa platser.Målet med examensarbetet är att ta fram ett system som åtgärdar dessa problem.Vi börjar med att ta fram en funktionsmodell att utgå från. Går vidare med val av hårdvara för modulen, och därefter vidare till mjukvaruutveckling.Resultatet av detta examensarbete är ett system för fjärrstyrning av Daikins värmepumpar som använder 3G-nätet och enkelt kan styras via en androidapplikation..
