The chapter explores the role that formal modelling may play in aiding the visualisation and implementation of usability and particularly experience requirements in an ambient and mobile system. Mechanisms for requirements elicitation and evaluation are discussed, as well as the role of scenarios and their limitations in capturing experience requirements. The chapter then discusses the role of ...

Introduction: The unprecedented, worldwide COVID-19 pandemic demanded the need for adequate personal protective equipment (PPE) health care workers (HCWs). commonly recommended N95-mask (N95) needs further optimization in areas of technology, re-usability, and comfort. LEAF-mask (LEAF) reportedly offers improved technology innovative features, however, neither them have been tested yet. Therefo...

The current state of the art in supporting e-learning objectives is primarily based on providing a learner with learning content by using metadata standards. Due to this approach, several issues have to be taken into account – e. g. limited re-usability across different standards and learning contexts and high development costs. To overcome these issues, this paper describes an innovative seman...

This paper introduces an automated rule discovery approach for IoT device data (S-LOR: Sensor-based Linked Open Rules) and its use in smart cities. S-LOR is built following Linked Open Data (LOD) Standards and provides support for semanticsbased mechanisms to share, reuse and execute logical rules for interpreting data produced by IoT systems. S-LOR follows LOD principles for data re-usability,...

During the last few years, expert system explanation has become an active research area after recognizing that its role goes beyond expert system verification as assumed by early systems. After examining current systems, it has been found that only a few of these meet the requirements of an end user interested in learning more about the domain being addressed by an expert system and understandi...

Web GIS (Geographic Information Systems) service systems provide the various GIS services of analyzing and displaying the spatial data with friendly user-interface. But, early systems don’t support open environment and interoperability. It is difficult to access diverse data sources, which provide each spatial data format. And, these systems have the difficult of upgrading the function and redu...

The performance of today's high-end microprocessors continues to grow. This increase in performance is due in part to the use of speculative, out-of-order execution, coupled with highly accurate branch prediction. However, even with branch prediction accuracies over 90%, many instructions are executed unnecessarily from the wrong path. This wrong-path execution results in cache pollution and un...
