Harsh environment low cost LIBS sensor for sub-surface CO2 leak detection in carbon sequestration

Jain J., Goueguel C.L., National Energy Technology Laboratory, US

The U.S. Department of Energy’s carbon capture and sequestration (CCS) program goals to reduce emissions of carbon dioxide (CO2) from anthropogenic sources will require great cost and effort. To ensure the success of the program [...]

Estimation of Algae Concentration in Water Using Spectrophotometric Measurements and First Derivative of Absorbance

AlMomani F., Örmeci B., Qatar University, QA

The occurrence of algae in conventional wastewater treatment plants or aerated lagoons can result in false indications in the final effluent parameters, such as TSS and CBOD5 . Algae plumes create surface scum, poor water [...]

Using Secuirty Monitoring Tool to Improve Operation of the Water Distribution System

Kroll D., Hach Company, US

The distribution system represents the last analytical frontier in the water quality industry. Since 9/11, numerous communities have installed multi-parameter monitoring stations in locations throughout the distribution system as early warning systems based on potential [...]

Test ASIC for Real Time Estimation of Chip Temperature

Szermer M., Kulesza Z., Janicki M., Napieralski A., Technical Univiversity of Lodz, PL

The main goal of this paper is to present in detail the design and operation of an ASIC, which will be used in the research aimed at the development of a real time temperature monitoring [...]

Multi-functional Wearable Device for Heart Health and Possition Assesment

Kaminska B., Simon Fraser University, CA

In this paper we introduce a wearable device combining physiological monitoring and person’s position assessment. An accelerometer is used as a multi-functional sensor for a position and heart mechanical performance measurements, known as mechanocardiography (MCG). [...]

Wireless Micro and Nano Sensors for Physiological and Environmental Monitoring

Kaminska B., Simon Fraser University, CA

A wearable physiological/environmental monitoring system and a practical implementation are presented. The technical requirements for wearable electronics and sensors have been specified with an example of ECG, oxygenometer, and wireless network-based bidirectional communication. A presented [...]

Smog Analysis in Urban Areas Using ASTER Data and Its Analysis of Variance with In-Situ Sensors Data

Roy P., Brumfield J.O., Vaseashta A., Graduate program in Physical Sciences, US

This paper describes an approach to assess atmospheric pollutant in the troposphere and their spectral characteristic signatures by using high-spectral and spatial resolution ASTER data and its analysis of variance with in-situ data obtained using [...]

Prevention and Risk Reduction in Heart Health

Kaminska B., Tavakolian K., Ngui B., Chuo Y., Carmichael B., Simon Fraser University, CA

Identifying early onset of cardiac disease is not easy and it is very expensive. For this reason the first symptom of cardiac problems is often catastrophic. It is the goal to produce a low cost [...]
