A Framework for Developing Real-Time OLAP algorithm using Multi-core processing and GPU: Heterogeneous Computing

The overwhelmingly increasing amount of stored data has spurred researchers seeking different methods in order to optimally take advantage of it which mostly have faced a response time problem as a result of this enormous size of data. Most of solutions have suggested materialization as a favourite solution. However, such a solution cannot attain Real- Time answers anyhow. In this paper we propose a framework illustrating the barriers and suggested solutions in the way of achieving Real-Time OLAP answers that are significantly used in decision support systems and data warehouses

A Context-based framework for mobile applications

Mobile applications have become commonplace in the past few years. In domains such as healthcare, app user experience becomes even more critical. If healthcare apps are not user friendly, patients simply stop using them, or worse still, they may use these apps with disastrous consequences. One approach to improving app user experience is to keep track of mobile context, which is any information that can be used to characterize the situation of an entity, where an entity can be a person, place, or object. In this thesis, a system was designed using the following features. Relevant, context-based alerts are provided to the users via the mobile application. The mobile context of the user is tracked completely automatically. Alerts prompt the user to interact with an underlying information system and also improve the user\u27s domain knowledge of the system. A proof of concept was constructed for the healthcare domain. Existing literature shows that user experience of apps is improved by ensuring the existence of the following features: Implicitly sensed contexts, providing the right information at the right time and reduction of user-input requirement. To establish the improvement in the user experience of the system, the features were measured against the research recommendations from existing literature. Based on these measurements and analysis, the hypothesis that the quality of user experience can be enhanced using context is found to be valid
