The paper examined the value system in Philippine firms against the backdrop of Eastern-Western cultural dynamics in East Asia. The Asian milieu presents co-existence of cultural stasis and unease -balance and tension between Eastern values and Western ideas. Successful Asian countries demonstrated their ability to blend conflicting cultures and highlight certain values in order to promote nati...

ELECT A fast tracking system is demonstrated that is based on single laser illumination and a few single-pixel single photon avalanche diode (SPAD) detectors that improves on the previous tracking of non-line-of-sight motion by a factor of 300 in laser power. With an average illumination power of only 2 mW, a 15 cm ×15 cm object located up to 2.5 m away is tracked whilst outside of the direct l...

There is a growing interest in photoplethysmography (PPG) for the continuous monitoring of cardio-respiratory signals by portable instrumentation aimed at early diagnosis cardiovascular diseases. In this context, it conceivable that PPG sensors working different wavelengths simultaneously can optimize identification apneas and quantification associated heart-rate changes or other parameters dep...

This article introduces a back-illuminated (BI) single-photon avalanche diode (SPAD) based on 40 nm CMOS image sensor (CIS) technology which is the most advanced node for fabrication of SPAD up to date. It's P-well (PW) and deep N-well (DNW) junction, DNW deeply implanted form wide absorption region resulting in very high photon detection probability (PDP). Thanks retrograde DNW, premature edge...

Humic acid fertilizer (HA) incorporation is a common method for improving crop growth and soil fertility. However, the effects of HA on rice are still unknown. We conducted two-year field experiment to determine radiation use, growth, yield grown with five different rates: 110 kg?ha?1 100% urea (pure nitrogen) (T1); 30% 70% (T2); 50% (T3); (T4), 1500 (T5). The results showed that T2 treatment h...

Threshold limit values (TLVs) are intended to protect workers from the severest effects of thermal stress and to establish the exposures to heat in working conditions. Earlier, acute heat strokes often occurred as a result of working in hot environments in Japan. However, acute heat strokes recently sometimes occurred in outdoor work environments such as industrial constructions and agriculture...

In recent years, there has been a growing interest in exploring the application of single-photon avalanche diode (SPAD) optical wireless communication (OWC). As photon counting detector, SPAD can provide much higher sensitivity compared to other commonly used photodetectors. However, SPAD-based receivers suffer from significant dead-time-induced non-linear distortion and signal dependent noise....

Single-photon avalanche diodes (SPADs) are widely used for weak light detection due to their high gain and sensitivity. Unfortunately, SPAD devices have random telegraph signal (RTS) noise during the transition phase, which makes circuit design more difficult. Therefore, modeling of RTS in is great significance processing circuits. However, not included traditional equivalent model. In response...

Rice is China’s main crop and its output accounts for 30% of the world’s total annual rice production. growth status closely related to chlorophyll content (called Soil Plant Analyzer Development (SPAD) values). The determination a SPAD value great significance health rice, agricultural irrigation regulated fertilization. traditional measurement method not only time-consuming, laborious expensi...
