The use of mobile devices has during the last years expanded and on the market you can see a huge amount of applications. The development of mobile applications differs from traditional systems development since mobility infers that mobile applications can be used in different technological and social contexts. Although previous research has recognized that mobility can present mobile application developers with certain challenges, empirical studies of how problems arise and how they can be handled has thus far been limited. In this study we focused on the requirements engineering process from a development view with the purpose of finding challenges emerging in the development process. The study is based on a qualitative case study that employed semi-structured interviews with both project managers and system developers active in the requirements process.

Using mobile technology to make ends meet is currently a reality for many people. More and more peopleare working while travelling or work from home. Most knowledge workers are equipped with laptopsand smart phones. To find out how individuals are affected by having the ability to stay continuouslyconnected and work with mobile business applications, we have conducted a case study and in closecooperation with a company have created a prototype of such a mobile business application. Fourindividuals have tested our application and were then interviewed.

The short term effect of phosphorus in sewage sludge was investigated to establish howmuch of this a farmer can grant him- or herself, if using sewage sludge as a phosphorusfertilizer. Possible differences in plant availability between sludge phosphorus precipitatedby iron, aluminum or calcium integrations were studied in a sandy soil at two pH levels.The sludges were analyzed using pot and incubation trials. As the intention was to investigategrowth limitation due to phosphorus deficiency, a soil with low phosphorus supplywas chosen as well as a low phosphorus application rate. Sludge corresponding to 12kg phosphorus per hectare was applied. Treatments fertilized by sludge were compared totreatments where 0, 6 and 12 kg phosphorus per hectare from mineral fertilizer was applied.Every treatment was replicated six times.

The heuristic methods used by the anti-trojan application TrojanHunter have been evaluated. The evaluation shows that the heuristic scan engine of TrojanHunter has a very good detection ratio and that the detection ratio can be even further improved by implementing the suggested improvements, the most important of which is a white list to avoid misidentifying files that are known not to be trojans..

Summary Title: How to make decisions on software based servicedevelopment in the mobile handset industry.?The Rapid Model for Holistic Application Evaluation Authors: Per-Inge AnderssonPatrik Dreveborn Tutors: Björn Regnell, Department of Computer Science,Lund UniversityRobert Wenglén, School of Economics and Management,Lund University Problem formulation: Academically the questions of finding out what constitutes a sound decision base and finding out how to handle the issue of a holistic approach must be addressed in order to make a well balanced and relevant decision model. The core question is which decision criteria to include and which drivers are important in estimating the status of the criteria? Practically to provide Sony Ericsson with a formalized evaluation process for decisions on software development that is transparent, objective and challengeable. Purpose: Academically to contribute to the field of decision making research by elaborating on how to make a holistic, rapid and rational decision model.

Real-time systems are required to answer to external stimuli within a specified time-period. For this to be possible, the systems behaviour must be predictable. The use of active databases in real-time systems introduces unpredictability in the system, e.g. due to their use of active rules. The behaviour in active databases is usually specified in ECA-rules.

AbstractThis study aims to investigate the applicability of well-recognized supply chain strategies based on product characteristics. Choosing the right supply chain strategy can be the difference between winner and loser in today?s competitive climate and science offers several recommendations as to which aspects that should be considered. Fisher (1997) and Christopher and Towill (2002) suggest that supply chain strategies should be based on what kind of product the company is handling and that, in order to know which strategy is the most appropriate, the products must be categorized. Some criteria developed for the categorization are lead time, forecast in demand and profit margin.

Behovet av att skydda sig mot plagiat har blivit allt viktigare. Med dagens snabba kommunikation och höga teknologisk standard, kan en mer eller mindre liknade eller exakt kopia vara på marknaden efter endast några få dagar.Den som plagierar sparar både tid och pengar. Att formge en tilltalande produkt, tar tid och kostar pengar, vilket gör att den som kopiera utnyttjar det någon annan formgivit och det arbete den gjort. Dessutom sparar den som kopierar mycket tid på att inte behöva marknadsföra produkten.De skydd som finns för produktens form och design, ges genom immaterialrätt som omfattar upphovsrätten patent, varukännetecken samt mönster - eller formgivningsskydd.Alternativ för den som ?bara? vill göra känt att man formgivit något är Svensk Forms Nyhetsregister.I uppsatsen redovisas några produkter som har blivit plagierade.

The main objective with this study was to investigate so called odd purposes acceptable when registrating property along with how social development affects these purposes, furthermore to investigate how the cadastral surveyors estimates a foreseeable time. Tradition and praxis is used for several obvious purposes such as housing, farming, forests, offices and industry. Praxis is yet to be defined regarding more unique purposes. There is no mention in the law about which purposes are found acceptable to assure the demands on suitability are met. Cadastral authorities are responsible for making sure the division into property units is uniform and rule of law-accordingly.

Innovation has been identified as one of the key factors for economic growth long ago. However, the emergence of ?knowledge century? further strengthened the role of the concept since proper management of the knowledge is essential to make the best out of the innovative capacity of the companies as well as the countries. This necessitates a balanced intellectual property rights (IPR) systems, since these rights provide the basis to solve the market failures faced by innovating firms by creating property rights over knowledge. There is an inherent dilemma between invention and diffusion.
