The widespread adoption of location-based services (LBS) raises increasing concerns for the protection of personal location information. To protect location privacy the usual strategy is to obfuscate the actual position of the user with a coarse location and then forward the obfuscated location to the LBS provider. Existing techniques for location obfuscation are only based on geometric methods...

In this study we will introduce a hybrid model to describe competition in a constantly developing market environment. A hybrid model referred here is a model that has both system dynamic and agent-based elements. Modeling effort begins from a literature review to strategic management and management of technology. From this background we build a model combining the theories from multiple theory ...

An interactive case memory (ICM) is a system that interacts with a human user to gather information about a problem, interpret that information and search a store of previous cases to find cases that may be useful in solving the new problem. Many of the commercially successful products that have been derived from research on case-based reasoning could be described as ICMs. ICMs are type of advi...

Frameworks for IT evaluation have been extensively discussed in the past. Until recently, research had concentrated on advancing classic approaches such as monetary cost/benefit considerations or strategic management matrices, but that constriction to known methods has considerably softened. More researchers now use economic models in IT evaluation. Their contributions open exciting new perspec...
