Abstract: 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 has been conducted in Environment and Pollution Engineering... More

Abstract: 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 things. As the speed gradually approaches the c, the particle’s mass also approaches zero along with its static mass due to the impact... More

Abstract: 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. Then, under the assumption that the target is moving at an average speed... More

Abstract: 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 switching of the transistors in the circuit and thus reduces the dynamic power... More

Abstract: 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 the absence of costly and reliable acquisition techniques. Traditional... More

Abstract: 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 both at the surface (12 m) and at 100 m AGL. The data were retrieved from European Centre... More

Abstract: 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 the saturation of the efficiency of...
