Comparative Studies of Hot-Wire Techniques for Moderate Intensity Flows

Journal of King Abdulaziz University-Engineering Sciences, 1997
Methods employing hot wire anemometer techniques in obtaining quantitative turbulence information in turbulent flows are numerous. These techniques, however, were tested in different flow geometries under different operating conditions. It is difficult to decide on a technique preference unless the different techniques are tested under similar ...

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

Advanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.

Validation of data analysis routines for a thermal probe apparatus using numerical data sets [PDF]

, 2008
Most thermal properties of construction materials used in the analysis of building performance have been measured under laboratory conditions, using a guarded hot box or hot plate apparatus. As a consequence, these properties seldom reflect the impact of
