HIGHLY SENSITIVE POROUS SILICON SENSOR: DETECTION OF ORGANIC VAPOURS USING PHOTOLUMINESCENCE QUENCHING TECHNIQUE

Saakshi Dhanekar/ S.S. Islam/ T. Islam/ Harsh

Porous silicon based sensors were tested in the presence of various linear aliphatic alcohols (methanol to n-hexanol) and water in the range of 10-100 ppm by photoluminescence quenching technique. An increasing trend in the degree of quenching was observed with the chain length of alcohols while minimum response was given to water. Sensitivity as high as 80-90% and nearly instant response time has proven the sensors to be highly efficient. Photoluminescence quenching phenomena is discussed on th(..)

Jori Reijula/ Toni Rosendahl/ Kari Reijula/ Paula Roilas/ Heikki Roilas/ Raimo Sepponen

A simple but dependable electronic device, Con-Dis, has been developed to gain reliable information on elderly persons’ perceptions of their well-being. The device has been tested and proven to be technically functional and dependable. It was tested in two care homes for the elderly and two private homes to evaluate whether it provided reliable information about the service quality. This report illustrates the practical usage of the device and shows its efficiency in gathering reliable service q(..)

LAMB WAVE BASED MONITORING OF PLATE-STIFFENER DEBODING USING A CIRCULAR ARRAY OF
PIEZOELECTRIC SENSORS

V. T. Rathod/ D. Roy Mahapatra

In this paper we propose an efficient way of localization and parametric identification of metallic plate-stiffener debonding. A concept and experimental results based on a circular array of Piezoelectric Wafer Active Sensors (PWASs) is presented. Implementation of this circular array of PWASs combines the Lamb wave technique and symmetry breaking in the signal pattern to monitor the growth of a debonding of a stiffener on a metallic plate. Wavelet time-frequency maps of the sensor signals are e(..)

APPLICATION OF INTELLIGENT CONTROLLER IN A BALL AND BEAM CONTROL SYSTEM

Mohd Fuaad Rahmat/ Herman Wahid/ Norhaliza Abdul Wahab

Ball and beam system is one of a nonlinear and unstable control system, thus providing a challenge to the control engineers and researchers. There are a number of controllers which have been studied for years that can be used to stabilize the ball and beam system. This paper investigates the performance of few different control approaches that consist of conventional controller, modern controller and intelligent controller for a ball and beam system. It will involve the derivation of the mathema(..)

SENSORS FOR MONITORING COMPONENTS, SYSTEMS AND PROCESSES

T. Jayakumar/ C.Babu Rao/ John Philip/ C.K. Mukhopadhyay/ J. Jayapandian/ C. Pandian

The application of sensors encompasses many sectors of industry. In this paper, we outline different sensors – Raman distributed temperature sensor, sensor based on nano ferrofluids and MEMS based ultrasonic sensors. The development and application of these sensors for monitoring performance of systems and processes are discussed. Further, we also discuss the application of acoustic emission and infrared thermal imaging for process monitoring.
