Thermal Stress analysis of unidirectional composite material by FEM modeling
(2017-01-17)
Micromechanics of composite is study of complex mechanism of stress and strain transfer between fiber and matrix within a composite as well as distributions of physical fields inside heterogeneous medium. It was used ...
SHAPE OPTIMIZATION OF HELICAL COIL TUBE FOR MAXIMIZING HEAT TRANSFER
(2016-12-20)
Many researchers have observed the enhancement of heat transfer in coiled tubes compared to straight tubes with the same diameter and length. It is known fact, that in a helical coil tube the maximum axial velocity shifted ...
SMARTWALKER – ROLLING WALKER INSTRUMENTATION AND DATA ACQUISITION SYSTEM DEVELOPMENT TO MONITOR, VISUALIZE AND STORE ROLLING WALKER USAGE DATA
(2016-12-20)
The Smart Walker project was designed to fill a necessity of monitoring in real time the use of rolling walkers (RW) and study the causes that contribute to the high rate of fallings among its users. The main objectives ...
Numerical Modeling of Capillary Driven Microfluidic Flow
(2017-01-05)
Capillary driven two dimensional axisymmetric and three dimensional asymmetric flow in various microfluidic applications have been modeled and analyzed numerically. The transient Navier-Stokes equations are solved using a ...
FIBER BRAGG GRATING (FBG) SENSORS FOR THE SIMULTANEOUS MEASUREMENTS OF STRAIN AND TEMPERATURE
(2016-12-19)
This research presents a single fiber Bragg grating (FBG) sensor that is capable of measuring the axial load and temperature simultaneously. The FBG sensor is coated with a block of recrystallized Lophine, which introduces ...

Non-Invasive Measurement of the Internal Temperature of Heat-Generating Bodies
(2016-11-30)
While the surface temperature of a heat-generating solid body can be measured using a variety of methods, there is a scarcity of techniques that exist for non-invasively measuring the temperature inside the solid body. ...
SYSTEM HEALTH MONITORING USING MULTIPLE-MODEL ADAPTIVE ESTIMATION TECHNIQUES
(2016-12-22)
Monitoring system health for fault detection and diagnosis by tracking system parameters concurrently with state estimates is approached using a new multiple-model adaptive estimation (MMAE) method. This novel method is ...
