This paper considers the communication system assisted by a fixed-trajectory unmanned aerial vehicle (UAV), which is equipped with a reconfigurable intelligent surface (RIS). For this UAV-RIS assisted system, we jointly optimize the power allocation and active beamforming at the base station (BS) and the passive beamforming at the RIS, by a novel phase block coordinate descent algorithm framework aimed at maximizing the system sum-rate. Specifically, the joint optimization problem is decomposed into two phases, and we propose two optimization algorithms: one for BS power allocation using fractional programming (FP) and the other for jointly optimizing active and passive beamforming using FP-manifold, which alternately optimize two phases. Simulation results not only highlight the rapid convergence and evident superiority of our proposed framework but also reveal that the optimal UAV-RIS placement is related to the flight height. © 2012 IEEE.

Over past few decades due to hectic schedule and careless behavior of human much of disease has arises in form of life killer. Among several Heart diseases is one of the most leading destroyer diseases around the globe. Only a precise and timely forecast of this disease can aid in its prevention. Although many ways have been presented to assist professionals, each algorithm has its own set of obstacles. To improve the prognosis accuracy with low false alarms a new ensemble algorithm has proposed in this paper. To show the effectiveness of proposed approach it has simulated with the traditional and modern algorithm. The results indicates that proposed approach has improve prediction accuracy significantly. © 2022 IEEE.

Total communication in sign language involves hand gestures as manual signs and facial expressions as non-manual signs. Both types of signs have an important role in communication. Research related to sign language translators focuses more on manual signs. Ignoring the non-manual components causes the translation of spoken language to be less precise because of the loss of information from the signer's facial emotions. Indonesian Sign Language (SIBI) is different from other sign languages. SIBI follows the rules of the Indonesian language, which consist of structure and syntax. This paper proposes a framework for sign language translation composed of manual and non-manual components. Two propositions will be tested and contribute to this research. The first proposition is related to the use of sign gesture detection and segmentation methods using optical flow-based methods, and the second proposition is associated with the use of STMC, Facial Expression Recognition, and Transformer methods at the stage of recognition and translation of sign language. The proposed work arrangement is expected to improve performance measured by WER, BLEU, and METEOR and reduce computational load as measured by processing time. © 2023 IEEE.

The surging global demand for energy is primarily fueled by a burgeoning world population and elevated living standards. However, with traditional fossil fuels like oil dwindling in availability, there is an urgent need to shift towards renewable energy sources. Given the rapid progress in renewable energy technologies, a key objective of the project is to develop a solar energy tracking panel that can rotate for enhanced power generation. This innovative panel, capable of adjusting its position to optimize energy output by tracking the sun, proves invaluable in monitoring power consumption. The design of this rotatable solar energy tracking panel, incorporating four essential components (solar energy tracking panels, light-dependent resistors (LDRs), an Arduino, and a motor), is intricately explained in this study. This configuration not only serves as an advanced educational tool but also provides engineering technology students with a comprehensive understanding of alternative energy sources like solar power.

The efficiency of energy in cloud computing (CC) is one of the critical and vital parameters for large server-based networks due to CC consuming a great amount of energy and the dramatic energy consumption growth in the area of digital services. Focus on cloud computing energy consumption and efficiency is one of the key issues in a modern data center structure for operation costs reduction and fulfilling the green computing goals. Machine learning plays an important role to optimize the operation of cloud communication to enhance energy efficiency. This paper provides an overview and details of employing machine learning (ML) to propose energy efficiency solutions in the green cloud communication environment. The paper also presents a background and literature view. Moreover, we will discuss the ML proposals for green cloud resources management. Furthermore, deep Mind AI in the cloud, trends, and challenges in the cloud data center © 2022 IEEE.

Forecasting plays a key role in several industries to predict the probable requirement of a certain product or service over a period of time. This may or may not be dependent on certain external factors depending upon which, a suitable method needs to be chosen to perform the forecasting task. For a given data distribution, the best-fit model needs to be figured out after fine-tuning its hyperparameters to acquire the most optimal forecasts. In this paper, we have used the Prophet model of Facebook, an additive regression model to forecast the requirement of pesticides to be used for agricultural needs, and presented an overview of how fine-tuning the parameters leads to optimal curve fits, hence resulting in better-quality forecasts. We have also studied the impact of the size of the train data on the overall quality of predictions. Hence after combining both the data size and parameter values, the curve fits and predictions have been visually illustrated.

Some people may have trouble communicating with others because of motor and speech difficulties brought on by accidents, strokes, or diseases. Paralyzed people often struggle to communicate their demands, which can make even the simplest tasks challenging. People with disorders like dysarthria and amyotrophic lateral sclerosis may have trouble following conversations. The proposed method for automatic detection of everyday basic desires will help those with dysarthria and quadriplegic paralysis has more fulfilling lives. The device accomplishes this by monitoring brain impulses, which it then converts into either perceptible voice commands or messages that can be delivered to a healthcare provider's smart devices, depending on the user's preferences. The suggested method randomly displays an image of one of six basic requirements while using event-related-potentials(ERPs) detected from the Electroencephalogram (EEG) data to determine which need to fulfill. The dataset utilized for train, test, & validation was built using input from 10 participants. The proposed method had a 96.3|% success rate. © 2023 IEEE.

A 3D printed conformal Multiple Input Multiple Output (MIMO) antenna is proposed for 5G sub-6GHz and Wi-Fi 6E applications. The antenna is printed on a Ninjaflex substrate and consists of two identical radiators. An innovative 3D ladder-shaped structure is used as an isolating element between the radiators to reduce mutual coupling. The identical radiators have a fan-shaped structure engraved with a circular ring to operate in a dual band at a resonance of 3.35 and 6.6GHz. The overall footprint of the 3D printed MIMO antenna is only 45 × 25 mm2 and conforms to a -10dB impedance bandwidth of 40.54% (2.95-4.45 GHz) in the lower 5G sub-6GHz frequency band and 18.32% (5.95-7.15 GHz) in the upper Wi-Fi 6E frequency band. The 3D printed MIMO antenna demonstrates excellent radiation characteristics with a gain of more than 2dBi and efficiency of more than 95% in both the dual bands. The antenna's flexibility was also tested by bending it along the X and Y-axis at a radius of 30mm with successful results. © 2023 IEEE.
