Rolig eller orolig - en jämförande analys av seriemagasinen 91:an & Galago

Serier har sedan länge betraktats som ett andra klassens kulturella medium, med ett dåligt rykte som enkla och lättförståeliga. Majoriteten av seriemagasin ligger fortfarande i ett väntrum någonstans, för att då och då ytligt bläddras igenom; de tas inte på allvar. Och alternativen lyser med sin frånvaro; tillhör de inte skaran som ytligt bläddras igenom syns de nästan inte till överhuvudtaget. Uppsatsen tar sig dels an hur "de andra" ser ut, de som vågade och ville. Dels fokuserar den på vad som egentligen finns i de etablerade, ?lättförståeliga? seriemagasinen för att slutligen jämföra de båda med varandra..

Igenkänningen av förändrade porträtt : Kan förändring i proportioner hjälpa oss att minnas ansikten?

Det är tydligt att utseende påverkar vilka ansikten människor kommer ihåg och inte. Skulle det gå att öka eller minska igenkännbarheten genom att utföra små ändringar i ansikten mellan de tillfällen en person ser dessa? I denna undersökning har jag analyserat resultat från undersökningar genomförda av 170 personer och och kommit fram till att det är möjligt till en viss grad. Ytterligare extensiv forskning bör visserligen ske innan man kan bekräfta dessa studier, men skulle så bli fallet kan detta potentiellt påverka hur karaktärer i spel och andra medium designas..

Renar och klövvilt på järnvägar : en studie i järnvägars effekter på ren, älg och rådjur i norra och mellersta Sverige under 2005

Roads and railroads have significant impact on the surrounding landscape and the wildlife living in it. This study aims to provide an overview of the effects caused by railways to reindeer, roe deer and moose in Sweden in order to make more detailed assessments within this topic in the future. The method used is a study of literature on the subject and a synthesis of databases with information about wildlife mortalities, traffic intensity and fences in the study area; northern and central Sweden. The databases were used to compile digital maps using ArcGIS. Infrastructure brings change to the surrounding landscape and its function as habitat for wildlife. Railroads cause barrier effects such as fragmentation, wildlife mortality, loss of habitat and loss of connectivity.

Information bibliotek företag En utvärdering av EU-projektet "ITF på biblioteken i östra Värmland"

This report is the result of an evaluation of a project, conducted by five regional libraries. Through a training course the project should inspire small and medium sized enterprises to use modern information technology and Internet when searching for information. To evaluate the project, qualitative interviews were conducted with five librarians and quantitative questionnaires were distributed to all the course participants. The evaluation shows that the project goals were met, apart from the number of course participants, which was much lower than anticipated. It also shows that the project resulted in an increase in information technology and competence at the libraries, and that the course participants profit from their increased knowledge in their daily work..

Kuling - en digital bilderbok

In what way do pictures allow for freedom of interpretation and thoughts rather thanunderstanding reality in a high paced medium? Children today are exposed more thanever to images trough various media. Children?s culture in the digital world has, troughgames and apps, become more cross-generational than literature. Unfortunately, there aremany digital books that loose the story, as the creator gets lost in technology and/or ineducation and morals.

Inköpssamarbeten mellan oberoende företag

The aim of this paper is to present a case study that increases the understanding of pooled purchasing between independent companies, but also acknowledges the importance of relationships. While previous research has established the advantages and disadvantages of pooled purchasing, our paper shows that successful relationships can render additional synergies and benefits. At the same time, one must consider the time and resources needed to create successful relationships as well as the resulting interdependencies. These implications are well established within the field of purchasing and network theories. However, the authors believe that these implications need to be more explored in regards to pooled purchasing..

Habitat preference and dispersal of a sandassociated beetle, Apalus bimaculatus

Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and connectivity. Additionally, interactions between species (e.g. symbiosis), and how these interactions vary spatially and temporally can have a large impact on populations. When the range and habitat areas of a species continuously decrease, management strategies are often needed if the species shall be able to survive.

Utredning av variablerna som påverkar storleken på brytspänningen i lindningskopplare

Brytspänningen är den spänning som uppkommer när överkopplingsmotståndet i lindningskopplaren lämnar sitt föregående läge vid omkoppling. Storleken på brytspänningen i lindningskopplaren beror på hur stor läckinduktansen är. Är den inte känd så kan brytspänningen istället beräknas med hjälp av FEM-programmet ACE (internt ABB-program) i samband med Mathcad. I ACE beräknas först reaktanserna i p.u-enheter mellan lindningarna och hur stora de är beror på lindningslayouten. Det är tidskrävande att använda ACE och Mathcad och uppgiften är att utreda de parametrar som påverkar storleken på brytspänningen samt att ta fram en förenklad beräkning av densamma.Genom simulering i ACE av en mängd olika lindningslayouter visar det sig snart att det är alltför många parametrar som påverkar reaktanserna.

Konstruktion av datainsamlingskort för mätsystemet COMET

During test flights SAAB uses the data acquisition system COMET 16. The part of the system that receives the signals from the sensors and converts them is called KSM 15. The purpose of this thesis is to develop a data acquisition module on stacked PC/104 modules with a lower production cost. Our work has been divided into one part about analog signal conditioning and a second part with digital filtering and memory management of the sampled data. The analog part, designed of regular components like instrument amplifiers, voltage references, operational amplifiers and multiplexers, adjusts the sensors signal levels for the ADC?s that converts the signals.

Superkondensatorer kombinerat med batterier som energilager i hybridfordon

Detta examensarbete har syftat till att utreda hur man kombinerar blysyrabatterier med superkondensatorer. Batterier är ett vanligt medium för lagring av elektrisk energi. Ett av problemen de lider av är brist på uttagbar effekt, vilket är superkondensatorns starka egenskap. I examensarbetet har först fakta tagits fram och presenterats, för att sedan kunna göra en analys av bland annat effekt, energitäthet och verkningsgrader. Resultatet visar att hos en kondensator/batteri-kombination ökas effekttätheten med en faktor 3 vid ca 23% kondensatorviktandel vid 30-sekunders urladdning, medan den viktmässiga energitätheten minskar till ca 4/5 av batteriets energitäthet vid samma urladdningtid..

Dokumentation av en experimentell biogasanläggning

This thesis is   focused on identifying and documenting all   electrical equipment, such as devices, power lines / cables, and connectors in the facility and also on presenting a brief   technical description and information of the systems around the reactors.   Furthermore there will be a brief description of LabVIEW - which is a   graphical programming language- and which devices / elements   are programmed. For further notification, I am not   responsible for the programming of the devices in LabVIEW   which I have only used as a tool in my work. The plant   for production of biogas consists of four reactors   of which the third reactor (Lakbädden)   is connected to another reactor (UASB)   where they cooperate with each other.   The reactors are used for producing   biogas in the form of methane gas.The reactors I and II are   connected to, various electrical devices as, flow meters, temperature   sensors, frequency converter and   more.

Analys av mellanspänningsnätet i centrala delar av Västerås stad

The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

Lämplig röjningstidpunkt utifrån björkstubbskottens konkurrens

The purpose of this report was to investigate if there are any correlation between spruce medium height in young spruce stands and the number of birch stump shoots. The purpose was also to investigate if there are any correlation between the spruce height growth after clearing and the mean height of birch stump shoots. The reason for this investigation is that the problem with birch stump shoots after clearing can be expensive if there must be additional clearings before the first thinning. The study provides no apparent association and therefore no special clearance height is recommended. In the final stages of the work there are given some comments on the study´s weaknesses. Finally topics for further research are suggested..

Utveckling av beslutsstöd för kreditvärdighet

The aim is to develop a new decision-making model for credit-loans. The model will be specific for credit applicants of the OKQ8 bank, becauseit is based on data of earlier applicants of credit from the client (the bank). The final model is, in effect, functional enough to use informationabout a new applicant as input, and predict the outcome to either the good risk group or the bad risk group based on the applicant?s properties.The prediction may then lay the foundation for the decision to grant or deny credit loan.Because of the skewed distribution in the response variable, different sampling techniques are evaluated. These include oversampling with SMOTE, random undersampling and pure oversampling in the form of scalar weighting of the minority class.
