CARABAS III Konstruktion av antenninstallation på helikopter
This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.
Näringsämnesretention i fyra nyanlagda våtmarker i Falkenbergs Kommun
This study evaluates the retention of nitrogen and phosphorus in four newly constructed wetlands in the municipality of Falkenberg, Sweden. The four wetlands have been selected because they have been specifically constructed with the aim to reduce nitrogen and phosphorus in farming areas. The process of selecting the specific wetlands has been done in collaboration with the county administration in Halland. Through field studies in collaboration with the landowners where the wetlands are sited, the areas that provide the wetlands with water were determined. The size of these drainage areas were determined in a GIS computer program. The type of land use within the drainage areas was also determined.
Bildens godkännandeprocessi katalogproduktion : The image approval processin a catalog production
The objective of this thesis has been to investigate the approval process for an image. This investigation has been carriedout at four catalog-producing companies and three companies working with repro or printing. The information wasgathered through interviews and surveys and later used for evaluation. The result of the evaluation has shown that allbusinesses are very good at technical aspects but also that the biggest problem they have is with the communication. Theconclusion is that businesses need a clear construction for the image process.

Lönekartläggning och handlingsplan : - en undersökning om det aktiva arbetet för jämställda löner
Swedens membership in the European Union have resulted in an internationalcharacterized labour market. The construction sector is the area who employs mostposted workers among the 7400 employees who monthly enters the market. It?s alsothe sector where a big part of the work-related deaths occurs. The purpose of this studyis therefore to contribute to a greater understanding of the regulation regarding postedworkers, their work environment and the consequences of it.
Industriell produktion av loggia - en studie om loggiarum som alternativ till inglasad balkong
AbstractIntense competition in the building industry has forced building companies to develop highly efficient and optimised building solutions. This project, with a loggia that works both as an extended living room and a glazed balcony offers a highly economic viable alternative to standard balconies. This alternative is likely to attract build master since the area of the loggia will be part of the apartment area, i.e. included in the area for rent..
Axial- och gradientkrympning hos golv på mark enligt Eurokod 2 : Sprickbredders beroende av betongkvalité, tvångseffekter och armeringshalt
AbstractConcrete foundation slabs are usually exposed to unilateral drying during the curing process. The unilateral drying causes an axial shrinkage and a concave curvature of the construction. The curvature results from the fact that the upper part of the slab is drying and shrinking faster than the lower part. This is called gradient shrinkage.A problem occurs when the slab is considered fully restrained by adjoining structural parts. The deformations caused by axial contraction due to the constant part of the shrinkage and the curvature caused by gradient shrinkage of the slab are then prevented by the fact that the slab is fully restrained.
Ägarlägenheter : - succén som försvann
AbstractTitleOwnership apartments - The success that got lostDate of seminar2011-05-27Course/ProgramBachelor thesis/Construction and Real Estate Business ProgrammeAuthorsAnna ÅbergMarie Louise Homayon NejadMentorSven-Ola CarlssonExaminerGunnar WramsbyBackgroundThe 1st of May 2009 the government introduced a new accommodation form called ownership apartments. The government´s intensions were to give the individuals more influence in their housing, to increase the variety of accommodation and thereby create a freedom of choice when selecting their housing. They also saw opportunities to reduce segregation and increase the total production of houses and or apartments with this new type of ownership. The introduction was supposed to give the building companies a possibility to build with a new type of ownership and thereby create new and an increased number of projects for the future. This new accommodation form has however not gained the penetrating power that was expected.
Att lyckas som platschef i anläggningsbranschen
Att lyckas som platschef i anläggningsbranschenEva Karlsmyr Bygg- och anläggningsnäringen brottas med lägre produktivitetsutveckling än andra industribranscher och utveckling av ledarskapet ses ofta som en väg framåt. Kunskap saknas dock om vad effektivt ledarskap i denna specifika kontext är. Denna studie avser bidra med sådan kunskap genom att i en tematisk analys med kvalitativ ansats studera ledarskap ur effektiva platschefers perspektiv i ett svenskt rikstäckande anläggningsföretag. Utifrån meningskoncentrering av sju intervjuade platschefers berättelser har gemensamma aspekter av ledarskapet identifierats som respondenterna upplever avgörande för att lyckas i rollen. Studien har även undersökt hur dessa platschefer behöver påverkas av andra för att kunna utöva ett effektivt ledarskap.
"Tradition och religion kanske känns gammalmodigt" : En kvalitativ studie om gymnasieungdomars konstruktion av religion
The Swedish RE curriculum states that a major purpose and aim of education inreligion is to make the students accepting and understanding of people, regardlessof religious beliefs and conceptions of life. Previous research has shown that thereare tendencies indicating that these goals are not being attained thus Swedish adolescencespeak of religion and religious people in a stereotypical manner. Thesetendencies are causes of concern which is why this study seeks to make a contributionto the previous research. This research is required since there may havebeen a change in terms of results since the last study was made. In addition, resultsfrom research that are based on interviews are hard to generalize.
Partnering på Carlstad Conference Center : En jämförelse åt Byggbolaget i Värmland AB
Partnering is a new and exciting way of cooperation in the Swedish construction industry. In countries like Denmark and the United Kingdom the concept has been developed during a number of years while the Swedish construction industry has been more reluctant.Partnering is seen by many as the solution to the problems that often occur in design and build contracts. Many others believe that it is a way for the big entrepreneurs to gain unfair advantage. Never the less the concept is fast getting more and more appreciation, especially in the region of Karlstad where many new buildings are built that way.We have focused on the new development of Carlstad Conference Center (CCC) which is currently built with a partnering concept. The main method that have been used in this thesis are interviews with personnel on different positions in the project.
?För hur rock?n?roll är man som chef?? En diskursanalytisk studie av ledarskap i dagens folkbibliotek
The aim of this master thesis is to examine how leadership in public libraries is constructed discursively in the Swedish library field of today. The empirical material reviewed is job postings and articles from three library related journals.The thesis seeks to identify what different leadership discourses can be found by looking at definitions, forms of address, present actors and themes emerging. It also aims to examine the contingent presence of late modern leadership theories in the order of discourse. The leadership theories primarily investigated are New Public Management (NPM) and value-based leadership.The theoretical starting point of the thesis is discourse theory, developed by Ernesto Laclau and Chantal Mouffe. In the analysis a model of four phases is used; in which central concepts of discourse theory help identify the discourses.
Interaktion och intervention : En undersökning av kommunikativa behov hos personer med afasi och dysartri i vardagliga och kliniska samtal
In speech and language intervention, the ability to interact is seldom evaluated; rather intervention is evaluated in terms of improved testresults. If goal-setting in intervention also is based on everyday communicative needs, the relevance of the treatment may be increased and intervention outcome may be implemented in the patient?s natural environment.The present study, as part of a research-project, is based on analyses of interaction and interviews to examine everyday conversations and speech and language intervention. The aim was to explore if there is a relation between everyday communication needs and goal-setting in speech and language intervention for people with aphasia. A further aim was to investigate if there are everyday communicative needs that may form goals for speech and language intervention.Two individuals with aphasia and one individual with both dysarhtria and aphasia participated in the study. Three speech and language pathologists and two relatives also participated in the study.
VIBRATIONSSKADOR - FÖREKOMST OCH FÖREBYGGANDE : Analys av ett strukturerat arbetssätt inom bostadsproduktion
Ask any constructional worker and there is a high probability that this person knows a colleague with pain or other disorders caused by working with power tools.According to the Swedish Work Environment Authority 71 percent of the Swedish constructional workers is exposed to vibrations at least 25 percent of the working hours. Despite this, the number of reported occupational sicknesses caused by vibrations is as low as 1, 4 percent.JM Ltd. is one of the largest constructional companies in Sweden. Their main business is new housing and development of residential areas. God quality and low impact on the environment is a part of great importance in the company?s long-term goals.
Orsaker till förseningar i byggbranschen
Med anledning av JM:s satsning på Lean Construction, där företaget arbetar med att effektivisera verksamheten, syftar detta arbete till att identifiera frekvent försenade arbetsmoment och orsaker till detta. Arbetets datainsamling av olika typer av förseningar har avgränsats till nio tillhandahållna flerbostadsprojekt från olika delar av Sverige. Den data som har behandlats innefattar mötesprotokoll och tidsplaner som sedan låg till grund för de personliga intervjuer med arbetsledning för de olika projekten. Utifrån insamlad data och intervjuer genomfördes en enkätundersökning via Internet riktad till arbetschefer, platschefer och arbetsledare. Totalt blev 93 stycken personer från Stockholm och 95 från regioner inom affärsenheten Riks blev inbjudna att delta i undersökningen. Genom granskning av tillgängligt material kunde det konstateras att de arbetsmoment som vanligen upplever någon form av försening är:Arbeten under normalplanStällningsarbetenFasadarbetenHissmontagePlattsättningKöksleveranserVad beträffar arbeten under normalplan är brisfälliga geotekniska undersökningar en vanlig orsak till försening, vilket i sin tur kan leda till undermåliga bygghandlingar. Andra vanliga orsakerna till att ovanstående moment blir försenade är framförallt bristande styrning av egen personal och underentreprenörer.
