Konstruktion och prototypframtagning av pallväxlare

This thesis was conducted at AB Fredr Wagner in Ösmo in Nynäshamn, Sweden.AB Fredr Wagner provides solutions for the graphic industry and has been asked by acustomer to develop a product that can simplify handling of EUR-pallets, namely amechanical arrangement, further called pallet exchanger that can switch from anempty pallet to a fully loaded one using only hand force.The goal with the thesis was to create design documents for a pallet exchanger, andalso from those documents to manufacture a prototype for testing and evaluation.A field trip was made to the customer, IKAB mailing in Huddinge, where the palletexchanger is thought to be placed. The purpose of this field trip was to get an insightinto the current work condition and need of change, as well as to gather informationregarding the requirements when it comes to size and robustness of the palletexchanger. Existing equipment on the market that can perform similar tasks werestudied in order to find an optimal solution for the actual pallet exchanger.After the field trip and gathering of information the concept generating phase began.The method used for generating concepts was brainstorming. To decide on whichconcept to use, a concept selection matrix was created. The selection criteriaincluded in the matrix came from the requirements for the pallet exchanger.

Effekter av predationsrisk på sånglärkors (Alauda arvensis) habitatval på åkermark

Along with other European farmland birds, the skylark (Alauda arvensis) has declined rapidly since the 1970?s. Between 1975 and 2003, the Swedish population of skylarks declined with 64 %. In Britain, the decline is often explained by alterations in farming practices in general and the shift from spring-sown to winter-sown cereals in particular. The dense vegetation structure of winter cereals is limiting the number of breeding attempts possible, causing the entire population to decline.

Praktisk användning av Architechture Evaluation and Selection Method : Kvalitetsattribut som beslutsgrund

Mikael Svanberg skrev 2003 en doktorsavhandling där han beskriver en metod för att givet ett antal olika kandidatarkitekturer välja den som på bäst sätt uppfyller den blandning av kvalitativa krav som ställs på ett system. Denna rapport innehåller en fallstudie av Svanbergs metod applicerad på en webbapplikation beställd av GreenIT. Applikationen ska tillämpa en metod för mätning och relation av ansvarsfullt företagande med ett enkätformulär. Metoden bygger på principialkomponentsanalys (PCA) och är framtagen i ett examensarbete av Helen Josefsson 2009.Svanbergs metod, ?Architechture Evaluation and Selection Method?, appliceras på den beräkningstunga PCA-modulen i applikationen i syfte att utvärdera metoden med avseende på vilken kvalitet resultatet har, hur kostnadseffektiv den är samt när den lämpar sig bäst att användas.Tre stycken kandidatarkitekturer, Layers, Pipes and Filters och Blackboard, och fyra stycken kvalitetsattribut, Effektivitet, Pålitlighet, Underhållbarhet och Säkerhet, väljs ut och används som indata i metoden som bygger på Analytisk Hierarkisk Process (AHP).Metoden visar att Layers tillhandahåller den bästa blandningen av dessa kvalitetsattribut med stor säkerhet.

Tv-spel som kultur? : En kvantitativ studie över tv-spelens kulturella plats på folkbiblioteket.

This study examines the cultural place and status of video and computer games in the Swedish public library. Using works on popular culture and the theories of Pierre Bourdieu, this study employs quantitative methods, as well as textual analysis, to analyze the results of an online questionnaire with 19 questions focusing on selection criteria, shelf placement, perceived competence, as well as reasoning for having or not having these games in the library. 286 out of the 440 libraries contacted is participating in the study, and the libraries consist exclusively of public libraries in Sweden that are found in the database of the Royal Library.The results of this study show that a larger number of libraries than previously indicated have started to provide electronic games to their patrons. At the same time, patterns in the data and comments suggests that these games in many cases still do not enjoy the same level of cultural recognition as other media. Indicative of this is the way most libraries seem to focus on the medium being exclusively for their young patrons, with seem-ingly very little in the way of investment for adults.

Idéer om folkbiblioteket ? en idéanalys av ett urval kommunala biblioteksplaner

The aim of this master?s thesis is to examine which ideas about the public library that appear in a selection of municipal library plans and to examine if these ideas are unanimous. The comprehensive questions are: Which ideas about the public library appear in each municipal library plan? How do the ideas agree in the different municipal library plans? The sub questions are: Which judgements of reality appear in the different library plans concerning each municipality and its library needs? How do the municipalities define the concept of development and future demands in the municipality on the basis of the judgements of reality? Which recommendations do the judgements of reality give and how is the plan of action that is established in each library plan justified? Which fundamental views of reality, i. e.

Fjällfågelinventering i Dalarna : Vilka fågelarter finns där och i vilken miljö hittar man dem?

Studiens mål var att undersöka vilka fågelarter som hittas i Dalafjällen, i vilken miljö man hittar dem samt ifall det fanns en separation mellan arter i val av häckningsplats. Undersökningsytan kom att bli Drevfjällens naturreservat och koncentrerade sig kring högsta fjälltoppen Härjehågna. Sedan flera år tillbaka har detta område inventerats av Länsstyrelsen i Dalarna som en del i deras miljöövervakningsarbete. Data ifrån 2011-2013 års inventeringar användes till denna rapport. Fältstudierna bestod av två rutter där två inventeringsmetoder kombinerades: punkttaxering och linjetaxering.

Naturvärdesbedömning av Utanåfladen; En inventering av vårlekande fisk, bottenfauna och vegetation

There are several thousands shallow bays along the Swedish east coast. Most of them are disturbed by different human activities, and undisturbed bays can be considered as quite unique. In the sheltered shallow bays water warms up more rapidly than adjacent water favoring the growth of vegetation, which in turns is beneficial to spring spawning fish species like perch and pike. It is nowadays more common that coastal habitats are inventoried to facilitate future preservation and planning. The aim of this study was to investigate the shallow bay Utanåfladen (59° 53`31.38 N 19°00`44.90 E) in the north Stockholm archipelago and evaluate its habitat value.

Utopia Trek : utopibegreppets resa genom Star Trek

Humanity has always dreamed about a better world. These dreams has manifested themselves in the vision of Utopia - the good place, but also the non-existing place. Up until World War II man still wrote optimistic descriptions of this ideal world, and spread the idea through literature. In the aftermath of the atomic bomb and under the influence of the cold war, these publications seized to surface in literary surroundings. Despite this utopia did not die - it has only changed.

Orsaker till kalvningssvårigheter och dödfödslar hos SLB och SRB

Difficult calvings and stillborn calves are costly for the producer and lowering these frequencies can decrease the costs for the dairy operation. Each calving in the herd is registered by the farmer and stored in a central database. The information is used to monitor the level of calving-difficulties and stillborn calves in the herd and nationally. Monitoring of these registrations is important to detect possible changes. Breeding-value prediction for calving traits is based on the calving information in the database.

Förändrad urvalsprocess : En uppsats om varför urvalsprocessen för stridspiloter ser ut som den gör

I denna uppsats tas frågan upp om vilka drivkrafter som låg bakom förändringen i urvalsprocessen för stridspiloter under 70-talet. 1970 skedde en reform av urvalssystemet där det gick från ett karakterologiskt urval till ett stegvist urval. Det karakterologiska urvalet baserades till större del på psykologiska intervjuer medan det stegvisa urvalet var en rad olika tester som riktade sig mot vissa specifika områden inom flygandet. Även i det stegvisa urvalet använder man sig utav psykologintervjuer men det är inte längre den övervägande största delen av informationskälla för UTK. Arbetet är upplagt som en hypotesprövning där forskaren ställt upp fyra olika hypoteser för vad som var drivkraften bakom förändringen i urvalsprocessen.

En publik i förändring : En kvalitativ studie om det individualiserade tittandet i relation till användandet av VoD-tjänster

Purpose: The purpose of the study is to gain a deeper understanding of influencing behaviours concerning individualized viewing in relation to VoD-services (Video on Demand), and how this reflects the perceived viewing behaviour in terms of habits, content and social actions.Theory: The theory that primarily underpins this study is Jacob Bjur?s thesis Transforming Audiences. Bjur?s thesis provides an analytical model of individualized viewing behaviour that has been used in this study case. The model is founded on three central tenet areas of individualization, Habitualness that ensures habits, Socialness that refers to the social space and Referential space that ensures content/selection and viewership as a referential act.Method/Material: The study is based on a qualitative research method underpinned by focus groups interviews.Results: The research demonstrates strong tendencies towards an individualised viewing behaviour in the use of VoD-services.
