Computing devices already permeate working and living environments; a trend which is expected to intensify in the coming years. However, the direct interaction smart devices often have with the physical world, along with the processing, storage and communication of private sensitive data pertaining to users’ lives, bring security concerns into the limelight. This paper presents Web Service Acce...

A two-fluid hydrodynamic model of a two-dimensional gas-solids fluidized bed is used to calculate the shape of an isolated bubble. The calculations are done by applying four different discretization schemes to the convection term. The bubble shape calculated by using the first order upwind scheme is unphysical and pointed, where as the bubble shape calculated by the second order schemes SMART, ...

In this paper, we propose Conflict Manager to resolve conflicts for context-aware applications in smart home environments. Conflicts arise when multiple users access an application or when various applications share limited resources to provide services. In order to resolve conflicts among users, the Conflict Manager assigns priority to each user so that the user with the highest priority can b...

A smart home requires cognitive assistance to analyze and understand the behavior in this sensory rich environment. In this paper we explore the potential of a self-organizing fuzzy neural network (SOFNN) as a core component of a cognitive system for a smart home environment. We develop a cognitive reasoning module that has the ability to adapt its neuronal structure through adding and pruning ...

Ambient Intelligence (AmI) systems aim at augmenting real environments to create Smart Spaces where users are provided with pervasive virtual services. In order to allow users to seamlessly complete their tasks across a multitude of smart devices, and across different physical locations, the AmI infrastructure must be complemented with ubiquitous Intelligent User Interfaces able to adapt the in...

The health care domain is a culmination and emergence of many other economic sectors that give different services from patient treatment to healing, protective, rehabilitation, palliative care. GDP consumes facilitate in terms smart device development, clinical examinations, outsourcing, tele-medication facilities. Asian countries less developed with high population rate are facing related issu...

OBJECTIVE This article presents the results of an exploratory study in which 14 clinical and staff subject matter experts (SMEs) at a regional rehabilitation hospital were interviewed in order to understand how and why over-the-bed tables are used. BACKGROUND It is important to understand how and why a device or environment is used when designing it, and not just what features and functions a...

In this paper, we introduce a novel health and sleep nursing assistant called “Helena” for real-time, contactless, non-invasive monitoring that can be mounted on bed frame to continuously monitor activities (entry/exit of bed, movement, posture changes), vital signs (heart rate respiration rate), falls from in pervasive computing manner. The smart sensor senses vibrations generated by body move...

An energy aware routing protocol (EARP) is proposed to minimise a performance metric that combines the total consumed power in the network and the QoS that is specified for the flows. The algorithm uses source routing based on the functionalities provided by the Cognitive Packet Network (CPN), running autonomously at each input node to the network based on smart packets which gather relevant in...
