Besides the need for low-cost instruments for air pollution measurement and detection, nowadays there are many concerns about air pollution due to the fast changes and used technologies. This research was applied using an MQ2 gas detector, and microcontroller/Arduino-Uno. The design steps included bonding and connecting readymade sensors, coding, and finally testing the device. Testing... More

According to the norm of identifying truth in this theory, and Newton’s first law as a basis that can look at the overall situation, and by virtue of the electron storage ring as an experimental fact, it is pointed out: Only in reality can there be inertia. Inertia represents the continuity of the development of... More

This paper presents a Doppler passive location method for moving targets with fixed single station using the Doppler frequency shift and time difference information. First, based on the relationship between frequency shift and path difference, the virtual path difference is calculated from the measured value of Doppler frequency shift by means of mean value correction....

Recent digital applications will require highly efficient and high-speed gadgets and it is related to the minimum delay and power consumption. The proposed work deals with a low-power clock pulsed data flip-flop (D flip-flop) using a transmission gate. To accomplish a power-efficient pulsed D flip-flop, clock gating is proposed. The gated clock reduces the unnecessary... More

In recent years, enhancement of underwater images is a challenging task, which is gaining priority since the human eye cannot perceive images under water. The significant details underwater are not clearly captured using the conventional image acquisition techniques, and also they are expensive. Hence, the quality of the image processing algorithms can be enhanced in... More

The effective earth radius factor (k-factor) has a refractive propagation effect on transmitted radio signals thus making its study necessary for the proper planning of terrestrial radio links and power budget. This study was carried out over the city of Lokoja, Nigeria, using ten years (2011 to 2020) atmospheric data of temperature, pressure and humidity... More

Building the foundations of Thermo-Photo-Electronics became possible only after the correction of thermodynamic errors in the traditional theory of semiconductor Electronics and Photo-Electronics. It is these errors that determined the output of the asymptotics of the operating parameters of semiconductor electronic devices, in particular, both the saturation of the limiting clock frequency of processors, and...
