Electrical and Computer Engineering Faculty Research & Creative Works
Wireless devices can be used to monitor and record a broad range of phenomena. Their advantages include ease of installation and maintenance and considerable reduction in wiring costs. The addition of battery power and radio communication to such wireless devices can result in a completely The operating environment of monitoring systems is often hostile, due to temperature fluctuations, humidity, electromagnetic noise, and other interfering phenomena. The system should be able to adapt to changing conditions to maintain dependability in its operations This paper presents the case study of adapting a flood detection device to the environmental threat of submersion.
A Technical Note On The Production Of Zirconia And Zircon Brick From Locally Available Zircon In Bangladesh
A.S. Md Abdul Haseeb
In this study, the potentiality of Bangladesh zircon as a raw material for zirconia and zircon brick production was examined. Decomposition of zircon (ZrSiO4) into zirconia (ZrO2) was attempted by using caustic soda (NaOH) as the decomposition agent. 5-10 μm size zircon, 5-30 wt.% NaOH, and decomposition temperatures ranging from 1300 to 1500°C were investigated. X-ray diffraction method using Mo Kα radiation was used in order to find out the extent of decomposition of zircon into zirconia. Zircon bricks of 0.06 mm× 0.06 mm× 0.025 mm shaped were made under a pressure of 15 MPa. Carboxi methyal cellulose (CMC) and …

Different types of superconductors have been investigated at small magnetic fields (Ba) over wide temperature (T) ranges at different Ba orientations. It has been shown that the temperature dependence of the characteristic field (B*), separating the Ba-independent critical current density (Jc) plateau (single vortex pinning regime) and the region with Jc(Ba) (collective pinning), can be attributed either to the temperature dependence of the magnetic penetration depth for Nb-film and MgB2bulk superconductors, or to thermally activated processes for Bi-based superconductors and YBa2Cu3O7−δ superconducting …

We investigated a simultaneous temporally and spatially resolved 2-D velocity field above a burning circular pan of alcohol using particle image velocimetry (PIV). The results obtained from PIV were used to assess a thermal particle image velocimetry (TPIV) algorithm previously developed to approximate the velocity field using the temperature field, simultaneously captured by an infrared (IR) thermal camera. By tracing “thermal particles,” which were assumed to be virtual particles that corresponded to pixels of temperature values in successive IR images, the TPIV algorithm estimated a larger scale instantaneous velocity field than either a single-point velocity measurement (e.g., LDV) or the …

Fiber-Optic Temperature Sensor Based On Interference Of Selective Higher-Order Modes, Enbang Li, X L Wang, Chao Zhang
Faculty of Engineering - Papers (Archive)
A fiber-optic temperature sensor based on the interference of selective higher-order modes in circular optical fibers is described. The authors demonstrate that by coupling the LP01 mode in a standard single-mode fiber to the LP0m modes in a multimode fiber, and utilizing the interference of the higher-order modes, a fiber-optic temperature sensor which has an extremely simple structure and is suitable for high-temperature measurements can be constructed. The sensing principle, temperature measurement experiments, and results are presented.
