Kartläggning och analys av kundorderprocessen vid Ericsson AB
i Borås

Ericsson AB i Borås är en del av Business Unit Transmission & Transport Networks (BTTN), en affärsenhet inom Ericssonkoncernen. Enheten tillverkar och tillhandahåller trådlösa och optiska transmissionssystem. På grund av häftiga marknadssvängningar, som stundtals genererar så pass hög orderinläggning att vissa underleverantörer har svårigheter att leverera enligt överkommelse, uppstår materialbrist och leveransförseningar. Denna omständighet och det faktum att vissa kunder inte tillhandahåller Ericsson några prognoser, leder till omfattande omplaneringar som i sin tur medför extra arbete som inte tillför kunden något mervärde. Syftet med examensarbetet har därför varit att kartlägga kundorderprocessen samt huvudplaneringens arbetsrutiner för att sedan analysera och framställa eventuella förbättringsförslag för att reducera antalet omplaneringar.

Träbroar för järnvägstrafik

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Lactobacillus reuteri som probiotisk terapi mot bakteriell vaginit hos avelsråttor :

Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as well as in different diary products for humans. In this EEF-work I have shown that L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for breeding. In a breeding stock with 3000 animals some animals had a vaginal infection with ??haemolytic streptococci group G.

New Generation Surface treatment for tools : A preliminary study

The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.

Strindbergsbilder i gymnasiets litteraturundervisning : En analys av fyra läromedel i svenska

The purpose of this paper is to study the image of Strindberg that is conveyed in four different textbooks for the upper secondary school. How do the teaching authors choose to portray Strindberg? Do they focus on any one particular aspect of his writing? Adjacent to this a subsidiary aim is to see if teaching authors highlight the fictional nature of Strindberg?s works or choose to encourage a biographical interpretation. The work consists of a study of four literary history textbooks in the subject of Swedish for the upper secondary school, from 2000 to 2012. In the selected material the sections focusing on Strindberg and his writings are closely read and critically analysed.

Användarutbildning på webben

User education is an important aspect of university libraries' service to its users. This Masters' Thesis is about online user education. The aim of this study is to analyse five Swedish online user courses in relation to information literacy and learning theory. The web-sites were explored through textual analyses to find how concepts of information literacy and learning theory are expressed. The theoretical framework is based on Carol C Kuhlthau's three levels of user education, Paul Ramsden's three theories of teaching in higher education and Christine Bruce's different aspects of information literacy.

DATORSTÖD FÖR ARBETE : KONSEKVENSER FÖR VAL AV AFFÄRSSYSTEM En studie av en service- och supportavdelning

This report is focusing on problems with introducing standard enterprise resource planning systems (ERP) in businesses. A study has been carried out on a service and support department at a Swedish heat metering company, SVM North Node. The study aims to help the company become a better customer in choice and customization of a new ERP system. We make a description of the department studied and the work carried out there, on the basis of learning, knowledge and cooperation. As a final point we present some ideas on how computer systems could support their work, hoping that this will result in them making adequate demands on a new ERP system..

Den ekonomiska lönsamheten för solvärme i Sverige

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

Energioptimering av Hemsö fästning med förslag på energieffektivare systemlösningar

The report is a master thesis about energy efficient measures for an underground facility Hemsö fortress.Several proposals are evaluated economically.Statistics of the electricity used and measurements of several heat pumps are analyzed to find energysavings potentials.The results indicate that several units of a dehumidification system are responsible for over 70 % of theyearly electricity cost. The air that is being dehumidified by these units can otherwise cause damage ofculturally important interior designs.The proposal with highest profit suggests an alternative method for dehumidification. The cooler in theair handling units in Hemsö fortress have capacity to dehumidify the air. However complementary fansneed to be installed to circulate humid air towards the air handling units. The solution can be implementedin three different locations within the facility.

Prefabricerade ramper i stålfiberbetong

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Förekomst av Giardia i symtomfria valpkullar :

The flagellate Giardia intestinalis has been known to cause diarrhea in both man and dog. Results from epidemiological studies have indicated that transmission of the parasite from dog to man is plausible even though that route of infection has yet to be shown. Several international studies have shown that the parasite frequently occurs in asymptomatic dogs. In Sweden the prevalence of Giardia in healthy dogs is not known though. In this study, faecal samples were collected at two separate occasions from 21 litters and 21 bitches showing no symptoms from the gastrointestinal tract. The samples from each litter were pooled but the samples from the bitches were analyzed individually.
