Information overload is by no means a new concept, but has come to prominence the last decade. A generally accepted definition of the phenomenon does not exist. The main question in this master thesis is how to define information overload in order to create a connotative concept for information science. This thesis reviews the nature and causes of information overload, and considers possible solutions, both individual and technical, and their relevance to the information professional. The review of the results shows that researchers seldom or never give a legible definition of what the concept information holds.

The interest in providing a post 9/11 image of Islam to contrast the media?s frequent focus on its practitioners? alleged tendencies toward hostility and violence has in Sweden manifested itself (among other things) in an increased range of courses on Islam given by denominational Muslim organizations. In this paper I examine the construction of Islam by two Muslim organizations that offer education in Islam to non-Muslims in the context of the management?s stated goals of the education. My aim is to illustrate how discourses within these organizations are a result of the combination of local and global conditions..

This data consists of the company?s annual reports. Totally, 20 companies of different sizes under diverse economic conditions are involved in this data.Conclusion: After reviewing the companies? calculations, it is noted that the both models that are used reflect better stock-exchange rate during an economic recession..

Detta examensarbete omfattar utveckling och test av en metod för distribution av data i ett multidatabassystem. Testen av metoden har gjorts genom att den har implementerats i en fallstudie. Fallstudien berör en organisation som har behov av att integrera tre av sina databassystem. Detta för att information ska kunna utbytas mellan dessa. Integrationen av databassystemen har gjorts på ett sådant sätt att de data som distribueras från dessa skickas till en central databas, med SQL Server som databashanterare.Det verktyg som har valts att användas i examensarbetet för att lösa uppgiften är Data Transformation Services, DTS, i SQL Server..

I många sammanhang är det önskvärt att importera data från textfiler, excelfiler och liknande till en databas. För detta krävs att data i något skede översätts till en ER-modell (Entity Relationship), en modell som beskriver relevanta delar i ett databasschema. Modellen för hur denna översättning ser ut varierar från fall till fall.I det här examensarbetet har en applikation tagits fram för import av data till en ER-modell ur ett modellperspektiv i linje med Model Driven Architecture (MDA) ?. Vinsten ligger i att använda en metamodell som beskriver hur olika modeller för transformering från tabelldata till en ER-modell får se ut.

This degree project was conducted in collaboration with Husqvarna AB, the headquartersof which are located in Jönköping. The aim was to further develop the filler cap found onmore or less the whole of the company?s range of chain saws, in order to make it moreuser friendly.The present filler cap is not easy to open and close, especially when wearing gloves, andunder difficult conditions, which creates problems and prolongs filling time.On the basis of market surveys, different prototypes and tests, we have created anergonomically improved cap of a new shape, which can be moved in the axial direction,thus making filling easier..

Near Field Communication, NFC, is a short-range wireless communication technology that enables data exchange between devices in a secure way. A NFC phone has the potential to enable the convergence of wallet, phone and keys, but as many other technological innovations, the launch is struggling. We have discovered that technological innovation is only the first step. For an innovation to be adapted, there need to be business model innovation too. Many actors form the ecosystem of NFC and the business model for each service is still an unsolved problem.

The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.

Background: Recently, the Swedish food culture has expanded by leaps and bounds. Interest in food and cooking has taken more space in the Swedish welfare state. Products and icons, such as organic free range chicken or Per Moberg have had greater impact on the way we consume food. Consumers have become increasingly aware of what they should and should not be eating. With an increased interest in food, supply and distribution channels have become increasingly important for the major grocery retailers (Board of Agriculture 2011).

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

De senaste åren har molekylärbiologisk data växt explosionsartat. Ny teknik gör att information kan härledas ur data snabbare och mer än tidigare. Faktum är att det tillkommer så mycket ny data att de nya resultaten inte längre kan publiceras i artiklar. Dessa sekvenser av data finns istället bara åtkomliga i speciella databaser. Dessa databaser är tillgängliga för allmänheten dels genom att ladda ned dem eller att använda en Internet browser.Det har, för ett par år sedan, kommit en ny standard för att strukturera upp och lagra data på.

Due to a growing interest in communication in today?s society the demand for equipment that is used in communication networks increases while the competition between companies that produce this equipment grows. To meet the increasing demand and at the same time having a competitive product development many companies use some effective product design, such as the modular product design. When a modular product design is used it?s good to compare different module configurations for a certain product and to simplify these comparisons some tool can be used.

The purpose of this thesis was to examine if there where fallacies in the design solutions for the business system IFS Applications from a user perspective, and if so, correct these from a cognitive science approach.Data collection consisted of three main portions. These where; workshop, individual interviews and observations. The collected data was analyzed and resulted in identification of two main areas in the application that where found lacking.The result of the study showed that the usability for processing large amounts of data and the lack of customization where the main flaws in the application. Two low fidelity prototypes where created with the purpose of rectifying the underlying flawed design solutions that where identified from the collected data..

Dagens informationssamhälle har bidragit till att människor, maskiner och företag genererar och lagrar stora mängder data. Hanteringen och bearbetningen av de stora datamängderna har fått samlingsnamnet Big Data.De stora datamängderna ökar bland annat möjligheterna att bedriva kunskapsbaserad verksamhetsutveckling. Med traditionella metoder för insamling och analys av data har kunskapsbaserad verksamhetsutveckling tillämpats genom att skicka ut resurskrävande marknadsundersökningar och kartläggningar, ofta genomförda av specialiserade undersökningsföretag. Efterhand som analyser av samhällets befintliga datamängder blir allt värdefullare,har undersökningsföretagen därmed en stor utvecklingsmöjlighet att vaska guld ifrån samhällets enorma datamängder. Studien är genomförd som en explorativ fallstudie som undersöker hur svenska undersökningsföretag arbetar med Big Data och identifierar några av de utmaningar de står inför tillämpningen av Big Data analyser i verksamheten. Resultatet visar att de deltagande undersökningsföretagen använder Big Data som verktyg för att effektivisera befintliga processer och i viss mån komplettera traditionella undersökningar.

Creating a database to manage medical data is not the easiest. We create a database to be used for a presentation tool that presents medical data about patients that is stored in the database. We examine which of the three databases, MySQL with relational design, MySQL with EAV design and MongoDB that are best suited for storing medical data. The analysis i performed in two steps. The first step handles the database that is most effective to retriev data. The second step examines how easy it is to change the structure of the various databases. The results show that depending on whether efficiency or maintenance is most important, different databases are the best choise. MySQL with relational design proves to be most effective while MongoDB is the easiest to maintain..
