Air Induced Formation of Cs ₃ Bi ₂ Br ₉ /Cs ₃ BiBr ₆ Bulk Heterojunction and Its Dual‐band Photodetection Abilities for Light Communication (Adv. Funct. Mater. 46/2022)

Visible Light Communication System Using an Organic Bulk Heterojunction Photodetector

A visible light communication (VLC) system using an organic bulk heterojunction photodetector (OPD) is presented. The system has been successfully proven indoors with an audio signal. The emitter consists of three commercial high-power white LEDs connected in parallel. The receiver is based on an organic photodetector having as active layer a blend of poly(3-hexylthiophene) (P3HT) and phenyl C6...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

CS 2429 - Foundations of Communication Complexity

Linear programming is a very powerful tool for attacking hard combinatorial optimization problems. Methods such as the ellipsoid algorithm have shown that linear programming is solvable in polynomial time. Linear programming also plays a central role in the design of approximation algorithms. In fact, it is known that linear programming is P-complete, and this implies that if NP = P then for ev...
