Idag besöker vi inte längre webbplatser enbart via datorer, utan även mobiltelefoner och surfplattor. För att göra interaktionen på en webbplats användbar via flera olika plattformar blir det allt vanligare med responsiv anpassning. Denna utveckling ställer högre krav på den grafiska formgivaren som bör ha god kunskap om de plattformar som designen tillämpas på för att nå högsta möjliga användbarhet. En grafisk formgivare ska alltså förstå vad användbarhet innebär och hur denna kunskap ska tillämpas i designen. Kandidatarbetet undersöker vad som definierar användbarhet och vad grafisk design bidrar till i skapandet av responsiva webbplatser. Utifrån litteraturstudier i samband med en produktion i form av en responsiv webbplats, presenterar vi i detta arbete våra metoder för hur den grafiska designen ska uppnå användbarhet oavsett plattform. ---- We no longer visit websites solely by using computers, but also mobile phones and tablets.

This Master of Science thesis was a part of Pharmadule Emtungas project to construct a mobile automated cell for welding of carbon steel pipe (Heating, Ventilation and Sanitation). Pharmadule Emtunga is using a modular building concept for building pharmaceutical factories. The modules contain these pipes. The goal of the thesis was to present concepts for technical solutions regarding welding methods and fixtures for the cell. Conceptual models for the cell were made with aid of CAD software.

Z39.50 is a standard protocol designed to create an interface between diverse computer databases for diverse information needs. Since it has to be adjustable it is also complex and demands a certain degree of expertise when being set. However, the aim of this paper is not to make a theoretical description but to examine certain conditions in practice. From the perspective of Swedish research libraries two principal hypotheses are examined: 1) the implementation of a given technology (Z39.50) is primarily influenced by social circumstances, and 2) the way in which the technology is implemented will bias the results of information retrieval. For this examination we need a framework of theories concerning the relationship between technological development and society, organisational theories and database theories.

This thesis explores the effect of using a new media in the marketing mix. SL, in cooperation with Clear Channel, has covered the outside of an entire carriage, 46,5 meters long, in an underground train with an advertisement for a company. This new form of advertising has taken place in the Stockholm Underground system during spring 2005. The five companies participating in this project are MTV, the Aftonbladet/Sportsbladet, Eniro 118 118 SMS, Heinz and the Gallerian.An empirical study has been carried through to survey the motive for companies to market themselves, their brand and product/service, by using the outside of a carriage on an under-ground train as a gigantic, mobile bill¬board. The study also investigates the commuters? attitude regarding this form of advertising.

Något händer när ny teknik gör intåg i klassrummet där undervisning, studier och lärande i olika ämnen står på schemat. I nästan varje elevs ficka finns idag en populär artefakt, mobiltelefonen. Att telefonen påverkar skolkulturen är förståeligt. Men hur anser lärarna att elevernas användning, kommunikationsrutiner och strategier för studier och lärande påverkar undervisningen och attityderna till skolarbetet? I skolan har man traditionellt alltid använt artefakter som myndigheterna har tillhandahållit, exempelvis böcker, penna och papper.

Marknaden av smarta mobila enheter blir sto?rre och sto?rre och det kan vara ett bra sa?tt att na? ut med sin tja?nst eller produkt till den breda massan genom att driftsa?tta en mobilapplikation. De applikationer som kan installeras pa? de mobila enheterna och som anva?nder sig av enhetsspecifika funktioner kallas native-applikationer och a?r bundna till en plattform. De kan da?rfo?r bara anva?ndas av de enheter som anva?nder sig av den plattformen.

Syftet med studien är att ta reda på hur tre olika innovativa tekniker kan användas för att samla in användarinsikter i en tjänstedesignprocess. Detta genomförs med ett designcase som handlar om besökarnas upplevelse av Norrköpings Symfoniorkesters konserter. Symfoniorkestern behöver hjälp med att locka fler besökare till konserterna och nya sätt behöver användas för att samla in användarinsikter för att få så många olika perspektiv som möjligt av konsertupplevelsen.Det var 20 personer som deltog i studien med en blandning av personer, dels de som idag går på Norrköpings Symfoniorkesters konserter och dels de som inte besöker dem. Deltagarnas uppgift i studien var att gå på två av deras konserter och dokumentera sina upplevelser med hjälp av tre olika innovativa tekniker: designsond, app och automatisk kamera.Resultatet av studien visar att den första tekniken designsonden gav en fördjupad bild av deltagarnas syn på konsertupplevelsen och hjälpte till att bredda fokus i tjänstedesignprocessen. Den andra tekniken,appen, kunde ge en mer detaljerad information i realtid om deltagarnas konsertupplevelse på plats.

Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

Detta arbete beskriver en examensuppsats i datateknik på Linnéuniversitetet.Röntgenavdelningen på SUS, Skånes Universitetssjukhus i Lund, använder en lättviktig flyttbar röntgenmaskin som väger endast cirka 90 kg, för röntgenundersökningar ute på äldreboenden.Bilderna överförs till sjukhusets PACS när maskinen är tillbaka på sjukhuset, genom att man kopplar in Dragon via kabel till sjukhusets nätverk.Målsättningen är att förbättra den trådlösa kommunikationen som för närvarande är för långsam och opålitlig, så att bilderna kan överföras till sjukhusets PACS direkt efter undersökningen.I detta arbete beskrivs vilka alternativ som kan användas.Samt om de mobila bredbandstjänster som finns tillgängliga i Region Skåne är bra nog för att kunna användas för uppgiften.Slutsatsen är att ett 3G HSDPA/HSUPA abonnemang kan vara tillförlitligt nog.Framför allt om extra redundans tillförs med dubbla SIM-kort som använder separata nät och att signalen förstärks med antenn placerad utomhus på transportfordonet.Transportfordonet används som brygga mellan Wifi och mobilt nätverk.Röntgenmaskinen kommunicerar med transportfordonet via Wifi.För de fall Wifi inte fungerar på grund av byggnader och omgivande miljö arbetades ett reservalternativ fram.Jag har också undersökt och jämfört DICOM protokollet mot FTP.Detta för att se om DICOM har en overhead som skulle motivera användet av FTP istället för sändning av bilder. Resultatet av jämförelsen visade att DICOM har 5-10 % overhead jämfört med FTP..

This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.

ABSTRACTThe principal aim of the study was to compare the feeding behaviour of cattle, sheep and goats on pasture and explain any differences between speices. Furthermore, I compared foraging behaviour between dry season and the beginning of the rainy season, in order to see any relationships between weather and behaviour.The study was carried out in Shompole in southern Kenya. Behavioural data were collected by observing herds of cattle, sheep and goats on pasture. The livestock were herded on pasture during the days and kept in bomas, where people live, during the nights. The weather in Shompole is characterized by high ambient temperature and low, bimodal rainfall.

In this composition, a study of consignment inventory on basis of the factors which are important for implementation and application of consignment inventory are made. Logistics chain from subcontractor to end customer is becoming more complex when the volume of items constantly increases to satisfy the needs of the market. From that perspective, companies had large inventories but today it is a lot of different solutions to streamline inventory management. One way that recently becomes increasingly common is to let the subcontractor fill up the customers stock using different approaches such as VMI (Vendor Managed Inventory). A further step in the evolution can be to make use of consignment inventory where the vendor owns the stock of the customer.

During the last years, the importance of sourcing in firms has increased. Globalization, fierce competition and an increased level of outsourcing are common explanations to why firms have highlighted the potential to realize savings and the value creation that the Purchasing department can generate. One trend that follows in parallel with globalization is an increased pressure from society on firms to take responsibility for the impact that its products and services have on the environment. This responsibility creates even more attention as outsourcing involves trade with suppliers in low wage countries, where the level of environmental and social responsibility is not always satisfying. The Purchasing department, the firm?s interface with suppliers should therefore, together with the firm?s Environmental department, play a key role in the firm?s contribution towards sustainable development.

The purpose of the study was to identify and analyse the implications of client virtualisation in company environments. The study chose to focus on the aspects of the current hardware, license management, application management, maintenance work and the implications virtualization would have on these. The work in the study was chosen to limit itself to a Windows environment.The background to the study was due to a growing need to be more flexible and mobile in company environments and in collaboration with the University of Jönköping a problem description and the framing of questions was defined. The essay tooka qualitative initiative to comprehend the complexity of the problem at hand. The empirical data was collected from interviews, literature studies and laboratory work testing applications.
