Anpassning av passivhus för ett kallare klimat - teknisk och ekonomisk analys
The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Inre och yttre faktorers betydelse för upplevelsen av arbetslivsrelaterade omställningsprocesser
Personalnedskärningar är ett resultat av det pågående oroliga arbetsmarknadsläget. Flera aktörer jobbar idag med servicetjänsten omställning vilket är en hjälp för arbetsgivare att hantera nedskärningar och övertalighet genom att få uppsagda medarbetare att komma vidare i ny sysselsättning. Trots en lågkonjunktur har omställningsarbetet visat på uppnådda lyckade resultat. Studien undersöker och sammanställer individers upplevelse av att genomgå ett omställningsprogram samt undersöker vilka faktorer som har betydelse för individers hantering av stressen i denna påfrestande arbetslivsrelaterad förändring. Tillämpningen av problemfokuserad coping undersöktes bland 71 deltagare som genomgått omställning i antingen kommunal eller privat sektor. Resultatet visade att deltagarna tillämpade problemfokuserad coping i relativt lika stor utsträckning oavsett yrkessektor.

Subjektiva och objektiva jämförelser mellan två benledningshållare, Softband och Adjoin
Background: Bone anchored hearing system is a surgically implantable system for treatment ofindividuals with hearing loss. The Softband is intended for patients who can benefit from a boneanchored hearing system but who are not yet suitable for implant surgery.Objective: The aim of this study was to investigate whether an adhesive bone conductor, Adjoin, canbe used as an alternative to Softband.Material and Method: Twenty adult subjects with normal hearing participated in the study.Measurement of functional gain and speech intelligibility was performed with Softband and Adjoinwhich then were compared. A questionnaire was answered by the participants after the measurementsthat treated their subjective experiences with each option.Results: The objective measurements yielded no overall difference between Softband and Adjoin forthe group studied. The subjective results showed differences in the perceived comfort as well as whichof the two bone conductors that would be preferred to use in everyday life, with Adjoin being thepreferred option. No difference was detected on participants perceived gain, sound quality and speechintelligibility.Conclusion: Based on the measured results, Adjoin seems to be a suitable alternative to Softband.However, there are questions about how Adjoin works with long-term use..
Dubbskador på Alvestakubb
Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process.

Integrerad stubbskörd och trädfällning
Denna rapport är ett resultat av ett examensarbete på civilingenjörsprogrammet Teknisk design, vid Luleå tekniska universitet (Ltu). Uppdraget i examensarbetet var att utveckla ett virtuellt koncept för integrerad stubbskörd och trädfällning åt Iggesund Forest AB/Olofsfors AB. I dagsläget sker trädfällningen och stubbskörden genom två separata operationer. Intresset för stubbskörd och skogens totala biomassauttag har idag ökat för att klara av de nya uppsatta EU målen med krav om att minst 20 procent av dagens energianvändning skall komma från förnyelsebara energikällor till år 2020, där skogen utgör en av de största förnyelsebara källorna. De stubblyftningsmetoder som används idag är inte helt optimala och effektiva för att det ska vara kostnadseffektivt att ta hand om stubbarna.En förstudie med en grundlig benchmarking gjordes över de olika stubblyftningsmetoder som används idag för att ta reda på och undersöka vad som fungerar bra respektive mindre bra med dem.
Konstruktion av formkropp pa JAS 39 E/F Gripen
The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.

Kakelugnar : en studie av Emil Petterssons kakelugnsmatriser
In recent centuries the Swedish Tiled Stove has varied in its design with an aesthetic evolutionary history that has not only followed the architectural and artistic ideals but also the taste in stove design. The heat source has varied depending on the regional traditions and where it was located within the country, but the inside of the construction was of a similar five channel system. The purpose of this paper is to study and compare the design of tile matrices made by Emil Petterson with other Swedish stoves. The following questions will be addressed:What characterized the production of a small scale tile stove workroom during the years 1900-50? Which main styles can be described as Emil Pettersson?s ideal while producing his matrices? And finally, is it possible to study the tile stove matrices as objects of historical and cultural significance, and what difficult methodological issues might occur in the doing of it? To answer these questions I will present the results of the documentation of Pettersson?s tile matrices with detailed historical categorizations and schedules. The conclusion shows that Pettersson as a stove builder and -producer was characterized by eclectic ideals and a design shape based on more liberal interpretations of contemporary trends.
