Design, Measurements, and Analysis of Enhanced Bandwidth UWB

Ambient computing enabled for body area networks have received much consideration over the past couple of years due to its applications in biomedical, healthcare monitoring, and military systems. Such systems are attracting users in other applications like gaming, fitness, sports, and other life style tools. The fast-moving lifestyle of people impelled them in a situation of less consideration of their health and sports, and it generated the need of healthcare monitoring and tracking devices. Advances in wireless technology and embedded technology have generated keen interest in antenna, mounted on or around the body to transmit or receive the vital data of human body to on-body or off-body systems. The proposed antenna is for the use in wireless body area network (WBAN), in UWB frequency range 3.1 GHz.-10.6 GHz. Enhanced bandwidth ultra wideband (EB-UWB) patch antenna consists of the dimensions 30 mm×27 mm×1.6 mm. The prototype is fabricated and tested in free space and on-body scenario.

Using Fuzzy Logic to Control Combined Cycle Gas Turbine During Ambient Computing Environment

The main aim of this article is to analyse and control a combined cycle gas turbine (CCGT) under normal and perturbation loading using a Fuzzy Logic Control (FLC) and an Adaptive Neuro-Fuzzy Inference System (ANFIS) through an ambient computing environment. The main characteristics of ambient computing is invisible, embedded, easy to use, and adaptive to name a few. The current article proposes the employment of FLC and to control the operation of CCGT considering the system inputs uncertainty. The target of the FLC is to maintain the system speed, exhaust temperature, and airflow within the desired interval. ANFIS helps to get the optimal control parameter and construct the proper rule base with an appropriate membership function with reasonable accuracy. The simulation results demonstrate the ANFIS controller's superior performance over FLC as well as the traditional controller for normal operating conditions and load perturbation.

Taxonomy on Ambient Computing

The rise of Internet-of-Things, Cloud infrastructure, and intelligent home solutions has resulted in the growth of Ambient Computing over the past decade. This article is an attempt to cluster the multi-dimensional research in ambient computing into relevant nodes. The author proposes a taxonomy in ambient computing, creating a logical arrangement of such nodes. An algorithm based on the cosine similarity function for calculating the distance between two ‘author keywords' has been used to spawn the inter-nodal relationships. The vocabulary for the research has been generated from IEEE Xplore taking into consideration the relevant journal publications. The taxonomy will guide researchers to the relevant published literature about a certain area of interest instead of exhaustive search into a plethora of published research in ambient computing. The taxonomy exhibits exponential growth of research in ambient computing over the last three years.

A Qualitative Assessment of an Ambient Display to Support In-Home Medication of Older Adults

Studies on ambient computing technologies have shown their potential for assisting older adults to manage medications. However, their results cannot be generalizable, since they were conducted in different settings. We assessed the feasibility of a Medication Ambient Display (MAD) to improve the medication adherence of low-income Mexican older adults with mild-cognitive impairment (MCI). Through semi-structured interviews to 11 dyads of older adults and family caregivers who used MAD, we identified the effects of the setting conditions in the adoption and use of our technology. Our results showed that older adults forgot less to medicate. However, we observed that seniors have risky medication-related behaviors as a consequence of the challenges impose by our setting, such as the lack of adequate pharmaceutical policies regarding the rational use of medicines and the follow-up on patients’ medication regimens. We outline design implications for developing ambient computing technology to reduce drug adverse events associated with these challenges.
