This paper presents the performance evaluations of the multicarrier modulation systems such as the Filter Bank Multicarrier (FBMC), the Filtered Orthogonal Frequency Division Modulation (F-OFDM) and the Universal Filtered Multicarrier (UFMC). The performance evaluation of these new waveform candidates for 5G mobile communications has been performed based on Power Spectral Density (PSD) and Peak to Average Power Ratio (PAPR) using MATLAB Version 2019. Simulation results show that, compared to the Frequency Division Modulation (OFDM), FBMC could be a more effective solution.

The Transportable Radio Frequency Monitoring System (RFMS) is a radio frequency or surveillance system installed at 64 well-known SMFR stations in the territory of Indonesia, which have pioneering airports and are controlled by 24 Technical Implementing Units (UPT) of the Ministry of Communication and Informatics. In this implementation, research was carried out to create a real time monitoring system for currents, voltages and power through a remote monitoring system. Therefore, the efforts made for this problem designed a monitoring system that can be accessed from the battery used to see the current, voltage and power parameters measured on the system with the sensor installed and transmit the data using internet communication media and the Blynk application as a display information so that battery.......

Numerical solutions to various types of plate structures are indispensible in engineering since it provides approximate solutions to mathematically expressed equation governing a plate. On the other hand, analytical solution provides exact solution to plate bending problems but has restrictions in areas of practical interest. In this study, an improved finite difference method (IFDM) which is a numerical method was used to transform the governing differential equation of a rectangular stiff plate on elastic foundation into improved finite difference coefficients using the central difference method on the discretized plate on elastic foundation. The coefficients obtained from the numerical method were applied into the governing differential equation of the rectangular stiff plate on elastic foundation to obtain the mathematical model for deflection of the plate. Thereafter, 25 interior nodal points of the plate were considered.......

With the spread of Covid 19 related information, so many conspiracy theories have resulted where most of these are widely circulated on social media. WhatsApp Messenger is one of the social networking sites where people depend on for information as this medium of communication is easy to acquire, to operate and that the internet bundles required to use the platform are quite affordable to many. It has been noticed that WhatsApp as an alternative channel that is interactive, inclusive and in multimedia form poses a threat to the right of citizens to be informed truthfully and accurately about the Covid 19 deadly pandemic. The WhatsApp platform has been heavily cited as a source of half-truths or totally misleading details about the cure and prevention of Covid 19. It is against this backdrop that this study sought to assess how the WhatsApp.......

Gas lift is considered the most important artificial method in the oil and gas industry. Although, there are several components in the Gas Lift Valve (GLV), the ball and the seats are the only two adjustable components. The objective of this study is to maximize the gas flow rate (throughput) using different seat designs, seat sizes, and ball sizes to increase oil production. Blowdown test has been conducted using actual valve and nitrogen gas at 600 psi injection pressure. In total, five main seat designs were experimentally tested to investigate the highest gas throughput. The first three seat designs (sharp edge, modified design, and optimized design) have previously been evaluated using low gas injection pressure. Developing on this study, these seat-deigns have now been tested using 600 psi injection pressure. Additionally, two new seat designs were invented in this research including partially curved design (PCD) and wholly curved design (WCD). To optimize the gas throughput, thirty-four seat sizes and five ball sizes were used........

This quantitative study was carried out to estimate the oil initial in place (OIIP) of the Safsaf D oil reservoir using both volumetric methods and a material balance equation. The study also assessed the oil reserves of this field using production Decline Curve Analysis (DCA) method. Oil initial in place was first estimated using three volumetric methods (Iso-pach method, Pore-volume method and Hydrocarbon pore volume method); furthermore, as these methods rely on mapping, Surfer software was implemented in this study to generate maps. Also, the modified material balance equation of the Havelena and Odeh model was used to estimate the oil initial in place. Field production history, reservoir pressure data, and PVT data were collected for material balance calculations. Finally, field reserves and remaining production life were estimated using exponential decline curve analysis method........

Paper Title :: Object Detection under Similar Interference Based on Efficient Det

In object detection, the most difficult interference is similar interference. The interference is relatively similar to the characteristics of the target object. When the interference feature extraction is less difficult than the target object, the use of the interference feature can better identify the target object. Therefore, a twin strategy, which uses interference with low detection difficulty, is proposed to provide the target object a non-single detection scale. Therefore, the interference and target objects are labeled at the same time, and the single classification problem is transformed into the multiclassification problem of detecting interference and target objects. Thus, interference is detected initially and does not interfere with the target object detection. Then, the EfficientDet model structure based on the twin strategy is proposed to study the object detection algorithm under similar interference. Finally, an experimental study is carried out. Experimental results show that the detection accuracy of the target object can be improved by more than 4%.
