- Abstract
Quality of Service is one of the most important research topics in cloud computing, both from the customer's point of view and the cloud service provider's point of view, due to the increasing number of cloud services and applications, along with the significant increase in users and workloads. Task scheduling has been a topic of discussion in many researches, some of which have proposed new ways to improve the Quality of Service in cloud systems. Recently, metaheuristic algorithms have been employed to improve job execution efficiency in such systems, which has proven effective in finding optimal task scheduling solutions. During this research, the latest metaheuristic algorithm Whale Optimization Algorithm (WOA) will be applied for optimizing task scheduling in cloud systems. Additionally, a multi-objective model for optimization will be used to achieve a balance between user satisfaction with these systems, and the requirements needed by service providers. Research results indicate WOA superiority in minimizing the execution time cost, price cost, and total cost parameters as contrasted with the current metaheuristic algorithms, which ultimately result in higher service quality.

OPTICAL fiber detectors , *ELECTROMAGNETIC fields , *MEDICAL technology , *SELF-efficacy , *HIGH temperatures - Abstract
The use of fiber optic sensor technology has rapidly evolved over the past decade, involving a variety of fields ranging from medical and engineering applications. increasingly used in places where traditional sensors are unable to work due to difficult conditions, Such as high temperatures, large sizes, and effects of electromagnetic fields. Unfortunately, the evidence of its use in medical and engineering is still unclear and scarce. This article aims to evaluate the current unique characteristics of the Fabry-Perot (FP) fiber optic sensor feasibility projects and to discuss a number of challenges related to the deployment of the different types of fiber optic sensors, their operation and application feature the hopes of empowering and inspiring possible future work. This research framework for scoping reviews methodology summarizes the results of 41 research papers over the past years, from 2024, outlining the research trend in medical and engineering applications. A literature search was performed, and an assessment was based on their content and significance. Potential applications of fiber optic sensor technology are broad. Based on the articles identified, Fiber optic sensor technology is classified into two categories: (1) applications in engineering, which have shown the highest contribution, and (2) applications in medicine. Although there has been a significant increase in the number of publications on the use of Fiber optic sensors within the last five years, there is, however, limited discussion to address Its actual engineering application combined with its medical application. It is evident that Fiber optic sensor technology needs to be further explored to focus more on doctors performing precise operations in hard-to-reach places, as well as in engineering applications such as measuring temperatures in reactors. It is envisaged that with sufficient development, the application of Fabry-Perot fiber optic sensors, will be promising and will improve their effectiveness, especially in medical and engineering applications.

ADDITIVE white Gaussian noise , *ORTHOGONAL frequency division multiplexing , *FREQUENCY division multiple access , *CHANNEL estimation , *WIRELESS communications - Abstract
Of the multi-carrier techniques under development is the Generalized Frequency Division Multiplexing (GFDM) which shows great potential and practicality, representing a departure from conventional modem schemes in a fairly unique and innovative manner. An integral aspect of GFDM is the matrix of subcarriers and sub-symbols that use spectral filtering, accomplished using an efficient pulse-shaping technique. Such a technique allows GFDM to retain signal characteristics in the frequency and time domains, thus ensuring effective suppression and spectral efficiency. Furthermore, this approach leads to a substantial decrease in Out-Of-Band (OOB) emissions. A major benefit that GFDM brings about is that it can provide a lower peak ratio (PAPR), which is compared with traditional OFDM. In addition to these developments, GFDM encounters one great challenge: the high complexity of the system and trouble in Bit Error Rate (BER) maintenance, which is a critical factor for ensuring correct communication. The current project is devoted to considering the practicability and efficacy of GFDM for the forthcoming mobile systems in particular. This page focuses on the performance enhancements achievable via combining Polar Codes (PC) as a coding technique within the GFDM architecture. We reasoned out the cases with Additive White Gaussian Noise (AWGN) and Rician fading channels. The next point is the efficiency of Zero Forcing (ZF) as a channel estimation method and how it is compared to conventional Orthogonal Frequency Division Multiplexing (OFDM) systems. Using this investigative discussion, we plan to draw a line connecting the enhanced GFDM algorithms with the adoption of the latest coding and estimation techniques, which will be the inevitable step to the next-generation wireless communication systems of the future. Adding PC & ZF to GFDM involves a process of using polar codes to improve BER by 0.1 at 16 dB. The new improvements are derived from different successful methods that pave the way for GFDM to be part of future generations. [ABSTRACT FROM AUTHOR]

The design of a 2D automated solar tracking system is addressed in the study that is being presented. This system's primary goal is to monitor the Sun's location and maximize the solar panels' energy output. The proposed study seeks to develop an automated tracking mechanism that positions the solar panel in the best possible position to gather energy using solar panel power output and Light Dependent Resistance (LDR). Two servo motors, one for each positioning plane, are used to move the solar panel. That Arduino was used to power those servo actuators. In order to control a servo motor that is attached to the solar panels, the regulating device used in this case is an Arduino Uno, which is straightforward to use. It does this by taking into account the output from solar panels and the inputs from LDR Sensor. Next, Arduino is used to put the complete program into operation. The given system's outcomes were contrasted with those of a single-axis system. The findings demonstrate that multiple exhibits can increase vitality by about 40%. Utilizing such monitoring systems in conjunction with photovoltaic installation systems is very profitable. [ABSTRACT FROM AUTHOR]
