Erfarenheter från Olika Produktutvecklingsprocesser vid Utvecklingen av en Atmosfärisk Vattengenerator
This Master of Science thesis was completed at the Department of Machine Design at the Royal Instituteof Technology in Stockholm in collaboration with Lund Faculty of Engineering, Luleå University ofTechnology and Stanford University. At Stanford University a global product development project wasrealized as part of the course ME310. The project was initiated by the American company ImmerseGlobal whose vision was to develop a new type of Atmospheric Water Generators, a machine that absorbsthe moisture in the air and via a water system transforms it to pure drinking water. The project was partlyfinanced by the Product Innovation Engineering program, a Swedish research and development programfor increased innovation capability in organizations.In parallel with the global project in the ME310 course the product development process was studied inorder to compare it with a product development course at the Royal Institute of Technology, IPU. Thetwo courses are similar to each other in several aspects.
Undersökning av ljudnivåer på skolgårdar : - samt hur fasad och fönster dimensioneras med uppmätta värden
This report is written on commission by WSP Acoustics. The report studies the outdoor sound levels on school yards in Stockholm. The questions given by the company to be answered was what are the actual sound levels at diffrent school yards with low traffic noise and how can you construct a facade element that reduces the sound level from the outside and meet the indoor requirements. Mesurements for four hours was done at eight schools set north and south of the city centre. The measurement period included one school break and one lunch break.
Frontlinjebyråkraten : en studie om de byråkratiska villkoren för yrkesrollen, den inomorganisatoriska kontrollen och samhällets påverkan
The purpose of this essay was to further develop the discussion around the street-level bureaucrats and the dilemmas that they meet in their work environment. The paper will try to accomplish this by putting the spotlight on the professional role, the organizational control of the street-level bureaucrat and the effect of society on the work environment. Something that also will be discussed is the well-known difficulty of implementation of new programs and methods, especially when street-level bureaucrats are involved. The street-level bureaucrats that this paper focuses on are caseworkers within Försäkringskassan and handle benefits and take decisions about the need for rehabilitation for people who are ill and unable to work.I have used a qualitative method for this study. The empirical material consists of six interviews at two different offices.The main cause of the dilemma of the street-level bureaucrat is that there is a conflict between the human side and the professional role.
En undersökning av politisk marknadsföring i Sverige: Samordning av budskap mellan kommunal och nationell nivå i svenska politiska partier
Political marketing has changed the way political parties internationally behave in relation to the voters. The purpose of this study was to investigate how political marketing is conducted on a local level in Swedish political parties, and how the local and national level of the political parties coordinate the message they send out to the voters. An explorative study was performed by interviewing experts in the field in the form of politicians on both a local and a national level. Initially the local parties' methods were investigated, followed by a second stage where we researched the link between parties on the local and the national level. Marketing of parties on a local level turned out to a large extent to follow traditional methods.
Recipientundersökning av Ensjön : Bedömning av sulfidmalmgruvan Enåsens eventuella påverkan på sjöns vattenkvalitet
Ensåsengruvan is a mine situated within Ljusdals municipality in central Sweden. Themine was in use from 1984 to 1991 and has since been undergoing a remediation program. Mine tailings from sulfide rich ore is a potential environmental hazard due to its tendency to cause acid waters and heavy metal leakage. Lake Ensjön is situated one kilometer from the mine area. Due to the hydrological conditions it was not expected to receive inflowing water from the mining area.
Synen på kön och jämställdhet i den svenska förskolan
The present Equality Project in the Swedish preschool has been studied according to its view on sex and equality. The purpose was to find out how the Equality Project is described, interpreted and implemented.The research questions focused the central concepts sex (gender identity, gender roles and gender patterns) and equality in the political level, the educational level and the executing level of the Equality Project. From each level some central texts were chosen and analysed.The results indicated that equality is interpreted as connected to an absence of gender patterns and gender roles. The concept of gender identity is differently understood in the different texts. The normative focus and the lack of psychology in the Equality Project are discussed..
Indexering av skönlitteratur en empirisk kvalitativ studie av indexering och språk
The aim of this essay is to investigate how patrons, librarians and indexers use subject headings to describe and index fiction literature. We wanted to know if the groups concentrated on different levels in the text from a semiotic viewpoint, where words either can describe the manifest/connotative meaning or the latent/denotative. To investigate this we had four fiction indexers, four librarians working with fiction for adults and eight library users read and index four short stories. After that we did interviews asking them about how they were thinking when describing the texts, how they use subject headings, about their opinions on indexing and, in the interviews with the librarians and indexers, about their usual work assignments. The subject headings they listed were analysed according to the level they described.
Rening av avloppsvatten med anaerob membranbioreaktor och omvänd osmos
This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.
Spillvärmeåtervinning ur kylvattensystemet ismältverket på Sapa Profiler AB i Sjunnen
The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.
Integrerat Performance Management System -En studie om ett ledningssystems påverkan inom Volvo
The research within the management control systems-field and more specifically performance management has been rather shallow and not much has happened the last decades besides the balanced scorecard. The researchers see a lack of studies focusing on the effects of an integrated performance management system and also how it affects the different hierarchical levels and the tasks to perform.We decided to perform an essay with case study-characteristics by looking at both the strategic and tactical level at Volvo Group, or more specifically Group Trucks. We performed three different interviews, one at the group level and two at the division level. The aim was to see what effect an integrated performance management system had on the tactical level (i.e. the divisions).Our findings and corresponding analysis suggested that Volvo was a rather centralized company in order to get the performance management system to work by enabling a ?weekly control?.
Nursing technique and growth environment of Rabbit fish (Siganus guttatus) in the area of Tam Giang lagoon, Thua Thien Hue
SummaryIn the area to the east of Hue city, in Vietnam, lays Tam Giang lagoon, one of Asia's largest lagoons, with an area of 22,000 hectares. This lagoon is suitable for aquaculture. One reason for this is because the salinity differs from sweet to salty in different parts of the lagoon. The Vietnamese Government advocates an increase in environmentally-friendly aquaculture and the fish Siganus guttatus (Rabbit fish) is a candidate for this. This fish eats mainly algae and can be cultivated in a polyculture.
Emotionsreglerings och emotionsperceptions betydelse för hälsofrämjande ledarskap
Syftet med studien var att ta reda på om det går att predicera medarbetares livstillfredsställelse, psykosociala välmående och upplevd relation till närmaste chef utifrån chefers emotionsperception och emotionsreglering. Detta gjordes genom att 38 chefer utförde ett datorbaserat emotionsperceptionstest samt besvarade Emotional Regulation Questionaire. Deras närmaste medarbetare bestående av totalt 213 stycken fick sedan besvara en enkät bestående av delar från Satisfaction With Life Scale, SF-1 och QPS Nordic. Studiens huvudresultat visade att generaliserat kan resultatet från emotionsperceptionstestet och det självrapporterade användandet av omvärdering av känslor hos chefer förklarar 28 % av skattningarna på Satisfaction With Life Scale hos medarbetarna. Resultaten diskuteras i termer av att chefer skapar en positiv atmosfär på arbetsplatsen, identifierar sociala problem och löser konflikter effektivare när de är skickliga på emotionsperception och omvärderar sina känslor..
Varför sviktar elevers intresse för matematiki de högre åldrarna? : Vilka faktorer ger elever motivationoch lust att lära matematik?
Drinking water is produced from raw water and is either from groundwater or surface water. This thesis aims to find out if the cleaning process of raw water is sufficiently effective. This is important because consumers are otherwise at risk of waterborne infection caused by pathogens. There are three groups of pathogens; bacteria, virus and parasite. These have different characteristics which mean that they require different water treatment to be separated.
Naturlig förekomst av arsenik och avskiljning av arsenik från grundvatten : test av olika filtertekniker avsedda för enskilda brunnar
During the last few years the presence of high arsenic (As) concentrations in ground water has been of major concern both internationally and in Sweden. Much evidence has been reported about toxic effects caused by arsenic. The carcinogenic effects and the possibility to measure the toxic impacts at low concentrations made the World Health Organisation (WHO) to reduce the guideline value from 50 to 10 ?g l-1 in 1993. In Sweden the corresponding reduction was implemented in 2003.
Several surveys in Sweden have shown that high arsenic concentrations may occur in ground water.
