Utveckling av takra?cken fo?r sla?pvagnar
This report is a bachelor thesis work in the field of product development and design. The assignment has been to develop a solution for roof racks, normally used for cars, to fit on the open trailer models FS1425 and Alugance. The project was implemented by Johan Andersson and Victor Karlsson, students at the Mechanical Engineering program with a focus on product development and design at Jo?nko?ping?s school of Engineering, in spring 2012.The client wants to use transport solutions in the same way as roof racks on cars. The user of such a product is assumed to desire simplicity, safety and an attractive design with an appealing price, which has been a challenge during the thesis work.Pre-studies have been conducted to examine the potential competitors and gain knowledge in the research area.
Mikroorganismer och antibiotikaresistens vid otitis externa hos hund. :
Canine otitis externa is a common reason for a visit to the vet. Predisposing
factors often complicate treatment and may result in a chronic disease
progression. All otic preparation for topical use in Fass Vet contain antibiotics,
corticosteroids and a fungicide. Sixty cerumen samples from dogs with external
otitis, sent to the Department of Bacteriology at SVA, were categorised according
to their profile of isolated microorganisms. Staphylococcus intermedius alone or
together with Malassezia pachydermatis were the most common organisms found.
Fifteen percent of the samples contained M.
Det sociala arvet : Kvantitativa analyser av intragenerationell (föräldrar till barn) överföring av utbildningsstatus och föräldra bakgrund
The aim of this study was to find relations between parents background and education ina wider sense and their children's success in school. The study also includes genusdifferentiations, the family profile and residential areas influence on children's ability anddetermination to study.The study confirmed earlier research that children's success in school is to some extentdependant on their parents education. At the same time it was shown that in most casesthe children reached higher level of education than their parents ? also when they werepoorly educated or had emigrated from a country with big cultural differences. It was alsoevident that children with at least one Swedish parent (and presumably Swedish as theirmother tongue) reached higher educational levels than other children.Children from single parent families often stopped their school carrier after the 9-yearcompulsory class while children of dual parent families more often continued to university.In general, girls were more affluent in school than the boys.
Den attraktiva arbetsgivaren: En kvantitativ studie om beståndsdelarna av och förklaringsfaktorerna till ett attraktivt arbetsgivarvarumärke -
Talented and committed employees are important resources for a company?s competitiveness. With the escalating competition for competent employees, a strong employer brand has come to play an increasingly important role as a means of attracting employees with a desirable profile. In this study, brand theory is applied to the results of a quantitative study of students? evaluation of an attractive employer, in order to identify the factors which explain why certain employers are perceived as more attractive than others.
Monteringslösning till dörrkarm
Dooria Sweden AB is one of the main door- and doorframe manufacturers inSweden. They deliver door frames for indoor use for project oriented buildingsites, for these types of building sites the doorpost comes pre-assembled. DooriaAB wants to minimize transport to reduce impact on environment and thetransportation costs of pre-assembled doorframes, this thru simplifying themethod of assembly.The main purpose of this thesis has been to develop a prototype solution thatbrings the three parts of the doorframe together with the same properties regardingstability and tightness of joints as the current method of assembly. A profile ofdemands and wishes were created in collaboration with Mårten Dragstedt, DeputyDirector of Dooria Sverige ABBy following the chosen method the authors have been able to produce a fullyfunctional prototype that meet the demands that were put on the product. Catia V5R20 has been used as an aid during prototype construction and virtual tests.
Optimering av driftläggningar i Fortums nät
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.
Organisering av komplexa organisationer - En studie av den svenska spårunderhållsorganisationen
To achieve a working collaboration in a big, complex organization where there are vast requirements on both quality and profitability is not always an easy task. An example of this is the organization that was created in the Swedish railway industry following a series of deregulations during the past 25 years. A partial market in this organization is the railway maintenance. In order to achieve a working collaboration between actors in this organization the so-called Purchaser-provider model (PPM) is presently used for the procurement of rail maintenance projects. Previous research has shown that this market-based instrument has clear positive effects regarding the cost-efficiency but hinders the collaboration.
Hur uppfattas företagets service av slutkonsumenten? :
We are two students of Horticulture management with marketing profile, now doing an extended course in Business Leadership within horticulture and agriculture. During our 2 years of studies we have used the same company once before, and this project is an expansion of a previous piece of work. We decided, in agreement with the company, to use an inquiry for our study. For this we have contacted 290 of the company's already existing customers. The primary purpose of the survey is to analyze the service offered by the company.

Undersökning av svetsförband med avseende på svetsgeometri, diskontinuiteter och blästring med stålkulor
Breakdowns of welded structures are usually a consequence of fatigue loading. Fatigue fractures are commonly initiated in the region close to the weld toe but can also initiate from the weld root and from discontinuities inside the weld. The purpose of this investigation was to examine the weld quality of welded joints produced at Volvo Wheel Loaders factory in Arvika. The goal of the investigation is to give a clearer insight regarding factors influencing the fatigue strength of the welded joints and thereby give a better foundation for fatigue strength calculations.The investigation is including examination of the weld geometry, weld discontinuities and the effects of shot peening. Mainly three different methods for collecting test data have been used: Plastic replicas cast on the weld profile, weld specimens from a rear frame belonging to a wheel loader of model L110E/120E and Almen testing of the shot peening.The results showed that it is not possible to control even transition between the weld material and the base material without after treatment.
Arbete över företagets gränser : En studie av organisationstillhörighet för konsulter i bemanningsföretag
Since the late 1900s, the consultancy has taken a firm grip on the labor market. The consultants' work profile has been secured through agreements such as guaranteed wages. The collective has been shattered as well as higher demands are required of the employee. This results in higher work demands, workload, a reduced staffing resource and hopeless wages which can lead to health problems and depressions. Previous research shows that consultants find it stressful to be associated with two companies and some clients can also point out consultant through different attributes.
"Här hymlar vi inte om sånt" : Synen på arbete och klass i Stig Sjödins Sotfragment och Jenny Wrangborgs Kallskänken
The purpose of this thesis is to examine how the public libraries work towards SFI (Swedish For Immigrants) based on the views of the overseeing librarians. To study this we have asked the following research questions:What distinguishes the public libraries? work towards SFI according to the responsible librarians? What distinguishes the communication between SFI teachers and the librarians according to the responsible librarians? What opinions are held by the librarians in regards to their work with SFI?We have used a semi structured interview method with seven librarians in charge of the activities with SFI at small and medium sized public libraries in a rural area of Sweden. The theoretical framework is composed of Marianne Andersson and Dorte Skot-Hansen?s model for analysis of the local public library profile and the authors? definition of collaboration.
Låt oss tala om integration : En studie av folkbibliotekariers syn på integrationsfrämjande arbete
Social exclusion is a problem in today?s society that we feel public libraries can help resolve since they are based on the idea of equality and openness. The purpose of this essay is to examine how public librarians think and reason about the concept ?integration? as well as what role public libraries can play in immigrants? integration process. With Jose Alberto Diaz? theory on the integration process, and Marianne Andersson and Dorte Skot-Hansen?s model for analysis of the local library profile as theoretical framework, we analyzed the responses from two qualitative interviews in small groups of 2-3 librarians from two different public libraries.
Roaming User Profiles : En undersökning av olika versioner och dess kompatibilitet
När Windows Vista introducerades förändrades mappstrukturen för hur användarprofilen sparas jämfört med tidigare Windowsversioner såsom Windows XP. Denna rapport undersöker kompatibilitetsproblem med Roaming User Profiles mellan äldre och nyare versioner av operativsystemet. Syftet med rapporten var att utreda vilka problem som kan uppstå, vad det gäller Roaming User Profiles, vid en övergång från Windows XP till Windows Vista eller 7. Undersökningen genomfördes med hjälp av laborationer, litteratur och tester för att hitta problemen såväl som lösningar till dem. Resultatet visar att profiler skapade med Windows XP inte följer med till Windows Vista eller 7 utan det skapas sammanlagt två olika profiler, en för det äldre och en för det nyare operativsystemet.
