Introduction Plant culture has found several applications for the powerful technique of goniophotometry, which measures and describes the characteristics of various sources of light. Because of the growing need for agriculture in controlled environments and the increased use of artificial lighting in plant cultivation, it is essential to understand the spectral distribution and spatial properties ...
Introduction For the performance of missions and the protection of people, defense and military applications need dependable communication networks. Electromagnetic interference (EMI) is only one of several obstacles that these systems must overcome. Interference from electromagnetic fields (EMI) may undermine military operations, endanger national security, and interrupt vital communication signa...
Introduction Digital oscilloscopes make it much easier for engineers to analyze and interpret the information contained in electrical signals. Design engineers have the potential to improve circuit functioning by learning more about signals, identifying problems, and using advanced methodologies for signal analysis. In this piece, we’re going to look at the numerous ways in which digital osc...
Introduction Humidity’s effect on material deterioration may be measured in environmental chambers. The purpose of humidity testing is to evaluate a product’s performance and durability in circumstances that mimic actual use. High-humidity conditions may cause a wide range of material deterioration, including corrosion, swelling, delamination, and a loss of mechanical capabilities; as ...
Exigences pour les appareils rotatifs de IEC60335 Standard General Scarifiers with rear discharge openings shall have a movable deflector, the closing torque of which shall not be less than0,30 Nm for machines with a cutting width of 300 mm or less, and not less than 0,40 Nm for machines with a cutting width of 300 mm to 600 mm. Discharge openings (chutes) When open discharge chutes are provided, no ...
Le transistor MOS a une résistance d'entrée très élevée. Cependant, il est également très sensible aux décharges électrostatiques (ESD) en raison de sa résistance d'entrée élevée et de sa très faible capacité grille-source. Le transistor MOS peut facilement se charger lorsqu'il est exposé à des champs électromagnétiques externes ou à l'électricité statique. De plus, dans des situations de forte électricité statique, il est difficile de décharger l'accumulateur...
