School zones are areas near schools that have lower speed limits and where illegally parked vehicles pose a threat to school children by obstructing them from the view of drivers. However, these laws are regularly flouted. Thus, we propose a novel wireless sensor network application called School zone Safety System (S3) to help regulate the speed limit and to prevent illegal parking in school z...
Fine-pitch backlight technology is rapidly evolving along with display technology, and chips are increasingly designed for direct integration modules. This study used a distributed Bragg reflector (DBR) mini light-emitting diode (mini-LED) backlights high dynamic contrast developed digital twin design by using (LED) (DBR).
با توجه به بحران انرژی در عصر حاضر و هزینه های بالای انرژی و استفاده روز افزون از منابع روشنایی، محققان در تلاش برای جایگزینی ادوات جدید با بهره و طول عمر بالا هستند. همچنین محیط زیست بحران دیگری است که در این عصر جوامع انسانی با آن روبروست. تولید تجهیراتی که دارای مواد سمی و آلاینده و همچنین برای انسان مضر نباشد از اهداف دیگر محققان است. امروزه به دلیل ویژگی های led، این قطعه نیمه هادی به عنوا...
Quartz-monzonitic porphyry stock at Kighal is located about 12 km north of Varzeghan, East Azarbaidjan Province, NW Iran. It has intruded older volcanic units during magmatic activities of Pyrenean orogenic phase and produced Cu-Mo mineralization and hydrothermal alteration zones in the region. The stock was intruded by numerous cross-cutting dikes mainly of dioritic to quartz-dioritic composit...
While technical characteristics, such as material used in the construction of display cases and their dimensions are important factors in terms of presentation quality as well as attracting the attention of the visitors, they can influence the inner air quality of the display case and preservation conditions of the exhibits too. This study intends to examine the effect of the technical characte...
This paper presents a design of a LED dot matrix written display system using Single Chip Micyoco (SCM). It completes the data acquisition function through the light pen with excellent photographic performance phototransistor, then it can achieve the following functions, such as click light, draw light, reverse display, entire screen erasure, stroke erasure, multi characters written and so on. ...
