Denna studie undersöker om, och isåfall hur, nätverksfördröjningar uppstår då små SOAP-meddelanden skickas över TCP/IP. För att utföra detta skapades ett litet nätverk och i det genomfördes mätning av svarstider för två olika SOAP-implementationer, Apache SOAP och Microsoft SOAP Toolkit. Resultaten från mätningarna analyserades och visade att det uppstår nätverksfördröjningar då små SOAP-meddelanden skickas över TCP/IP. Både Apache SOAP och Microsoft SOAP Toolkit uppvisade olika strategier i nätverkskommunikationen vilket påverkade svarstider. För Apache SOAP uppstod fördröjningar vid varje SOAP-anrop, oberoende av storleken på meddelandet som returnerades, medan Microsoft SOAP Toolkit undvek nätverksfördröjningar då meddelandet som returnerades var tillräckligt stort..

Web Services har vuxit i popularitet de senast åren. Användningen av inbyggda systemökar också ständigt, och möjligheten att göra inbyggda system tillgängliga via Web Services öppnar nya möjligheter.Detta arbete visar på möjligheter och problem med standardiserade textbaserade protokoll för kommunikation i inbyggda system med små resurser. XML-RPC och SOAP studeras ur detta perspektiv. SOAP befinns vara mer komplext att implementera stöd för än XMLRPC i den begränsade testmiljön, som har 32kB internminne. XML-RPC visar sig ge fördelar över proprietära protokoll främst när det gäller underhållbarhet och återanvändbarhet..

This work is about presenting the weave in a new and different context, by bringing textile and glass together. The work is characterized by material and shape experiments with silver and copper weave and hand blown glass. From experiments and sketches, the work has resulted in four sculptures, symbolizing four selected stages in a lifecycle; the birth, the development, the maturity and the death. One important part of the work has been to combine different materials and techniques.Studies of literature, sketching, handweaving and integration of silver and copper weave in the glass have been important methods in the working process. Inspired by the flower, the human being and the universe, a story about the life cycle has taken shape.The paper describes the working process with choices and analyses.

The taste of the dairy product is probably the main factor determining consumer?s dairy products choice. Consequently it is of great importance that the product tastes good and as expected every time. Off-flavors in milk can be caused by for example oxidation of the milk fat. Since copper is a prooxidant, a high copper content in the milk can cause oxidation.

The purpose of this paper was to identify the elements and the alloys that five objects found in Birka consist of and to examine whether there are any significant differences between the presumably imported and domestic objects. The material was analyzed using a scanning electron microscope (SEM) which was equipped with an energy dispersive X-ray spectrometer (EDS) in order to identify the elements that are present and the alloys that the objects are made of. Then the SEM results were compared with the results of previous analyzes that have been performed on finds from Birka in order to investigate how the objects differ in elemental composition and to find out if there are any significant differences between them. The results showed that the objects? content of the elements analyzed varies as the copper alloys the objects are made of.

Detta examensarbete, utfört på Valderas Consulting AB, ämnar att hitta ett tillräckligt bra sätt för att migrera ett personalhanteringssystem (HR-system) till mobila enheter, genom att undersöka skillnader mellan olika metoder för kommunikation mellan mobila enheter och en MS-SQL databas från ett säkerhets- och prestandamässigt perspektiv. Metoderna innebär att man implementerar en webbtjänst med hjälp av antingen REST eller SOAP för att utföra kommunikationen mellan mobila enheter och en MS-SQL databas. Arbetet innefattar även en undersökning av sårbarheter för mobila enheter och hur man kan lösa dem. För att kunna göra en jämförelse mellan metoderna, implementeras en mobilversion av HR-systemet i Android och en webbtjänst i ASP. NET.Resultaten från utförda experimenten visar att REST har betydligt bättre prestanda och använder mycket mindre bandbredd än SOAP.

Södra Cell Mörrum is one of the five paper pulp plants that are included in Södra Cell, and the paper pulp that is produced here is not only sold to Swedish paper mills. Most of the paper pulp is exported to different countries in Europe. In the manufacturing process the plant needs different kind of process water and there are guideline values for how much copper, iron and sodium this water is allowed to contain. Analyzes of this water is in the current situation done with an atomic absorption spectrometric instrument (AAS-instrument) with a flame. Measurements done with flame-AAS of samples that have concentrations near the guideline values for copper, iron and sodium, are not reliable. The reason for not being reliable is that the quantitation limits of these metals are higher than the limit values.

AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.

The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.

Desperate Housewives lockar tittare med sin sammanblandning av såpa, drama, action, komedi och deckare. Att berättarrösten i serien är en död kvinna, som från början har en av huvudrollerna, bidrar till attraktionen för serien. Det står klart att Desperate Housewives är en av få såpoperor som fortfarande fungerar på bästa sändningstid..

Soils in a metal contaminated site on Stångberget in Gusum in southeastSweden were investigated and compared to relatively unaffected soils a fewkilometres away. Pollution came from historical release of untreated flue gasesfrom a brass mill. The objective was to find information on how high the metalconcentrations are, if metals from the polluted soil affect the surroundings andif the metal contamination affects the microbial community. The soil wasinvestigated using several different methods, such as field XRF measurements,chemical analysis of metal, carbon and nitrogen content, pH, acid neutralizingcapacity, texture, soil depth, field leach tests, sequential extraction and microbialfunctional profiles. The study showed that copper and zinc concentrationswere above Swedish Environmental Protection Agency guidelines for lesssensitive land use on the entire investigated area.

Österbyverken is an industrial estate in Östhammars municipality in Uppland, Sweden. Many different activities have taken place on the estate the last 600 years. During the last 15 years both health and environmental studies have been made by different companies. At the most recent study a great increase of metals in Nerån, a river that runs partly through and partly next to the estate, was identified with mass balances. The purpose of this thesis is to accomplish a deepened study about the reasons for the increase of metals in Nerån.
