The globalization that has occurred during the last few years has made it more important for companies to have a well-functioning logistics system. Customers demand more options, which lead to an increased flow that creates greater demand regarding packaging and transports. Diverse logistics costs are nowadays a substantial cost for many companies. Therefore, more effort is aimed at optimizing transportation to lower these costs.The purpose of this project is to create a user-friendly calculation of logistics costs that illustrates how the costs vary, depending on how the flow is structured. This is done by examining which aspects that affect the total logistics costs and by mapping which aspects that should be included in a calculation of the logistics costs.Literature studies have been carried out parallel with empirical studies at Scania's production unit, MC, in Oskarshamn.

This essay is based on students' growing lack of interest in science at school. Both from a democratic and social perspective, this is a worrying factor for the future. Through observation, I investigated how five science teachers conduct their teaching. This is to get a better understanding of how teachers' behaviour in the classroom can affect students' interest in science. With a socio-cultural research approach, I have tried to highlight a few pieces of the puzzle that may explain students' declining interest in science.

Folksonomier, system som låter användare klassificera innehåll, blir allt vanligare på webben. Typiskt sker denna klassificering genom att användare fritt beskriver innehållsobjekt med hjälp av nyckelord. Denna uppsats presenterar en underökning av hur nyckelord förhåller sig till varandra hierarkiskt, inom ett folksonomisystem. Undersökningen är baserad på ett webbgränssnitt, där besökare kunde förfina eller förkasta förslag på hierarkier av nyckelord. Dessa förslag genererades utifrån av ett verkligt folksonomisystem. Efter analys av 400 inkomna svar dras slutsatsen att flera aspekter av metodologin måste förfinas för att tydliga resultat ska kunna uppnås. Förslag på sådana förändringar presenteras slutligen..

Human-computer interaction is central for computer assisted development. The aim was to investigate the user experience of a new (U2) compared to an old (U1) computer system, within a cognitive psychology frame of reference. Six subjects, frequently using the system, participated in the study. It was shown that the new (U2) compared to the old system (U1) enhanced and supported more the users? system related procedures/tasks.

The aim of this essay is to examine fan culture?s role in Swedish public libraries. I have interviewed, via email, six librarians who encounter and use fan culture in their daily work. The theoretical elements of my essay are based on a modified set of theories by Dorte Skot-Hansen that identifies six ideal types of cultural political rationalities. My study reveals that fan culture is used in Swedish libraries as a tool in increasing user participation in library activities.

I detta arbete sa? vill jag studera hur praktisk fysikundervisning och bedo?mning i na?grasvenska gymnasieskolor o?verenssta?mmer med modern forskning om fysikpedagogik.Denna forskning spa?nner o?ver ett brett spektrum av metoder och teorier, varav jag harfokuserat pa? om la?rarnas undervisning kan beskrivas som-elevaktiv eller inte,-mer eller mindre baserad pa? bokstudier,-inriktad pa? konceptuell fo?rsta?else eller mer fo?rma?gan att ra?kna specifika uppgifter.Dessa aspekter diskuteras a?ven i relation till de inblandade la?rarnas utbildning.Fo?r att kunna ja?mfo?ra de olika klasserna och la?rarna har jag anva?nt ett test avkonceptuell fo?rsta?else (FCI, se sektion 3.2) samt enka?ter till la?rare och elever. Ur etttyva?rr skevt urval av klasser och la?rare framga?r att det finns stora skillnader pa? hurla?rarna ser pa? undervisningen och vilka undervisningsmetoder de anva?nder, samt hurstyrt de upplever sitt arbete. Korrelationerna mellan elevernas resultat pa? FCI och pa?ordinarie prov pa? motsvarande mekanik a?r sma?, vilket tyder pa? att regulja?ra provma?ter konceptuell fo?rsta?else i liten utstra?ckning.

Companys usually have intern communication platforms where employees can gather information and communicate with eachother. These networks are not public which leads to less resources spent on development. If this network is also used as a work tool may inadequate usability decrease work effeciency. Thats why we, by using known design principles, evaluated an already existing network of this kind along with interviews and think out loud tasks for users. Four users had to do some tasks while they explained how they went through step by step to solve those. This report culminates into a couple of guidelines which can be used to create a user friendly network. The problems that prevented users to feel in control when working resulted in the following guidelines: Create shortcuts of frequently used functions.

LIBRIS is a national library search engine offering information about 6 million books, articles, dissertations and other materials held by Swedish university libraries, research libraries and public libraries. In December 2007 a new version of LIBRIS was launched, developed with focus on usability, simplicity and accessibility. This thesis examines how the new LIBRIS is used, what is working well and what could be improved and also what the users think of LIBRIS. The following report is based partly on a study of usability and partly on a series of tests where librarians, scientists, students and developers have executed a number of tasks while thinking aloud. The users also participated in an interview.

This thesis examines how role-playing games can be used as an educational tool in after-school programs and identifies the challenges and opportunities perceived by both students and teachers. The study is based on qualitative methods, with interviews with after-school teachers and children in after-school programs with their observations of role-playing activities in a municipality. The results show that role-playing games promote social development, creative thinking, problem-solving, and language development. Students reported increased motivation and engagement, while teachers observed improved relationships and an inclusive environment where students could explore different roles and perspectives. The research links these findings to previous studies that highlight the potential of role-playing games to develop empathy, collaboration skills, and critical thinking (Daniau, 2016; Trespalacios et al., 2011; Suryani et al., 2020). Furthermore, our findings support the curriculum goals of student influence and situational learning, emphasizing the importance of students' own initiatives and responsibility in educational activities (Lgr22, 2022). The study also identifies challenges, such as teachers' uncertainty about introducing and leading role-playing games due to a lack of expertise.

In the gaming industry, it has long been popular to combine genres with the aim ofcreating games that bring together the best of several worlds. However, there are stillmany unexplored combinations with good potential.This report addresses the planning and development of a game prototype that combinestwo game genres, turn-based and real-time strategy. In addition to presenting the results,the report also discusses the di culties that were encountered and how they were handled.The prototype contains a working combat system and a basic AI. The prototype ismodular, which means that it is easy for an end user to extend the game with extra content.Most elements that were considered important from the two genres were implemented, butthere is still room for improvement and further development.The result is evaluated by means of quality assurance, a process that is commonly usedin the gaming industry. The response has been generally positive, which indicates thatthe combination has potential and should be explored further..

Art in the city can be invisible until we talk about it. Letting children see public art in the context of play and narrative is a way to enhance creative thinking and knowledge as well as making the art visible. By creating a prototype for an art walk for children this study was able to create a scenery of children using different kinds of mediated narrative combined with a physical environment and movement. The theoretical framework of the project was picture books (Rhedin, 1991) transmedia (Jenkins 2006, Ryan 2004) and public art (Kwon 2002). The project?s aim was to create an empirical context for primary school children to explore public artwork.

Usability is a way to study how good a website is which is what our research builds upon. On a mission from Liseberg our purpose is to find out if their website liseberg.se is good from a user?s perspective. Our way of carrying this out where grounded upon a qualitative study through observations and following interviews with a number of participants. By compositing tools of method we have started with the theories descriptions of usability tests and we have also used the theories to be able to reflect around and to understand the results from the tests.

The Division of Language and Communication at Chalmers uses a web-based language tool, named EngOnline, to teach English grammar. The language tool suffers from some shortcomings. These include stability problems and an outdated interface but, above all, there is no documentation. Because of the lack of documentation and EngOnline?s need of maintenance, the Division of Language and Communication has decided to replace the language tool with a new and well documented one.The new language tool was developed using an agile work process; detailed documentation was replaced with more efficient communication.

The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.
