Investigation of recombination effects in dielectric barrier dischanrges : a model
Description :
peer-reviewed
,
This paper outlines specific variations in recombination coefficients for charged particles (electrons and ions) and how these variations affect the onset of saturation of atmospheric pressure dielectric barrier discharges (DBDs). By solving continuity equations for electrons and ions, ...

Investigation of TiO thick films as sensing layers in conductimetric pH sensors
Description :
peer-reviewed
,
Due to the increasing demand for accurate, reliable and highly sensitive pH sensors, research is ongoing to find new materials and methods to achieve this goal. An approach that shows promise in the pH-sensing field is the conductimetric pH sensor. It has the advantage of simpler constr...

Development of a portable gamma radiation mnitoring system
Description :
peer-reviewed
,
This paper demonstrates the feasibility of a portable gamma radiation monitoring system, based on the Anderson Current Loop circuit, where Nickel Oxide (NiO) thick films are used as radiation-sensing elements. A cost effective prototype system was developed for remote ionising radiation...

A wireless pressure measurement system based on TiO2 interdigitated sensors
Description :
peer-reviewed
,
The ability to monitor pressure remotely is of
particular importance in medical and environmental
applications as it is less labour intensive, safer and offers peace of mind to the general public. To meet this demand, a prototype system using TiO2 thick film interdigitated
capacitors ha...

Simulation and characterization of wireless data acquisition RF systems for medical diagnostic application
Description :
peer-reviewed
,
This paper presents an aggregation of simulated models for a wireless data acquisition system. The model consists of key units that were simulated using SIMULINK. The output signal from the transmitter was encoded to digital signal based on one of the Pulse Coding Modulation (PCM) algor...

A model for estimating the real-time positions of a moving object in wireless telemetry applications using RF sensors
Description :
peer-reviewed
,
In this paper, we discuss system and method of determining the real-time location of an omni-directional diagnostic radio frequency (RF) system while the object is moving freely inside an inaccessible organ. A target application to the human gastrointestinal (GI) organ is presented, sho...
