Fasader till industriella byggsystem - Metodik för värdering av fasadsystem

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.

Naruto mon amour : Maskulinitet i shonen manga

In this study I examine the representation of masculinity in the manga, Naruto. The manga is about the orphan Naruto, who, together with other children goes to a ninja school. Boys and girls study and practice together, at first sight seemingly without emphasized gender differences. As the story continues, the gender differences are, however, quite obvious and to the boys advantage.I find the difference between Naruto and other popular culture ususally presented to pre-bubertal and teenage boys to be considerable. Whereas the domination of women and the message that you can get as far as you wish, are common in American and west produced popular culture as well as in Naruto, the difference lies in how the success is achieved. The men in Naruto reach their goals by allowing their feelings to be seen and expressed.

Vägen till Gesällbrevet-En studie om samarbetsmöjligheter. The road towards passing the exam-A study of possible co-operation

Frisörelever har svårt att klara frisörbranschens gesällprov och antalet utdelade gesällbrev blir färre med resultat av ett ökat antal obehöriga frisörer verksamma i frisörbranschen. Syftet med studien var att ta reda på hur samarbetet mellan skola, handledare på arbetsplats och branschorganisationen ser ut samt att ta fram förslag till skolan hur skolan kan förbättra samarbete, kommunikation och information. Metoden som användes för att hämta materialet var kvalitativt med intervjuer av medlemmar från Svenska Frisörföretagarna och enkäter ifyllda av frisörer som har erfarenhet av att vara handledare åt elever under deras utbildning. Resultatet visade på brister med informations och kommunikationen mellan skola, handledare och branschorganisation. Samarbete mellan dessa kan förbättras och utvecklas till det bättre. Ett litet samarbete fanns mellan skola och branschorganisation men inte tillräckligt tillfredställande. Det fanns ett behov och vilja av att förbättra den delen. Samarbetet mellan skola och handledarna mindre bra och det fanns stort behov av att förbättra det.

Transformativt ledarskap - en förutsättning för produktivt teamklimat och egeneffektivitet?

In the faster growing pace of changes and competition in the global economy, factors promoting group effectiveness are of interest. How do components of leadershipstyle, especially transformational, team climate and selfefficacy correlate? To answer this question 3 questionnaires regarding leadershipstyle (MLQ), team climate (TCI-Short) and selfefficacy (self developed) were distributed to employees of a Swedish installation company (108 participants). Moderate positive correlations were found between climate and selfefficacy and between varying elements of leadership and selfefficacy. The leadership behaviour Contingent Reward correlated moderately with all climate dimensions and strongly with selfefficay.

Biblioteksutvecklingen i Göteborgs södra skärgård, Styrsö folkbibliotek, 1943-1976

The purpose of this thesis is to describe and analyse the road towards a modern library in the southern archipelago of Gothenburg between the years 1943 and 1976. The archipelago consists of about thirty smaller and larger islands, of which seven are inhabited throughout the year. Styrsö and the surrounding islands composed a municipality of their own until 1973. In January 1974 it became a part of the municipality of Gothenburg, this is also the year when the only bridge in the archipelago was ready to be taken into use, between Donsö and Styrsö. There is no bridge between the mainland and the islands.

EMC problematik och el-kvalitet i elkraftnät

The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.

Resebloggens relevans - innehållet som fångar läsaren

This study investigated whether in-situ audiometry, delivered via hearing aids, is a better option as a basis forprescribing hearing aid amplification, compared to conventional audiometry. By examining the real ear insertgain (REIG) in 29 ears (18 subjects), that had been fitted with a hearing aid programmed using both conventionalaudiometry and in-situ audiometry, the study looked at whether in-situ audiometry based prescription is closer tothe NAL NL1's fitting target than audiogram based prescription. The hearing aid Siemens Pure 7mi with speakerunit M was used on all participants. The results showed how in-situ audiometry based gain at certain frequenciesis more consistent with the target curve, especially at 1000, 1500, 2000 and 4000 Hz. It was not establishedwhether the findings of the study were statistically significant.

Beräkningsalgoritm för fouling i pelletervärmeväxlare inom plasttillverkning

Sweden?s energy consumption is divided into three major sectors. One of them is the industry sector. One third of Sweden?s energy consumption is converted in the industries.

Utvärdering av sökmaskiner - en textanalys kring utvärderingar av sökmaskiner på Webben

The purpose of this thesis is to analyse studies that evaluate Web search engines. This is done in four categories; the researchers? purpose, the evaluation measurements, the relevance, and the time aspect. Our method is based on a text analysis in which we use the direction of analysis of the content of sixteen evaluation experiments. Our results indicate fundamental differences in the way the researchers are tackling the problem of evaluation of Web search engines.

Påverkas hästens hudtemperatur av magnettäcken?

The market offers more and more products that are claimed to have medicallypositive effects (like increased blood perfusion etc.) due to their magneticproperties. The objective of this study was to investigate if blankets containingpermanent (static) magnets have a greater impact on cutaneous blood circulationthan ordinary blankets without magnets. Eight standard bred horses were used in across-over study. The cutaneous temperature was presumed to reflect blood flowin the skin and therefore thermography and local thermistors were used to indicatechanges in circulation. Baseline values were registered before the blanket wasapplied.
