Transformers are critical components in the electrical distribution system that function to increase or decrease the electrical voltage as needed. Variable load transformer analysis is an important study to understand the performance and efficiency of transformers under a wide range of operational conditions. Variable loads can affect the efficiency, voltage regulation, operating temperature, and life of the transformer. The efficiency of a transformer is affected by power losses consisting of copper loss (related to load current) and core loss (related to voltage). Efficiency is usually higher at full load and decreases at low load due to the significant contribution of core loss. In addition, load fluctuations can cause voltage variations on the secondary side, which requires adjustment through a tap changer to maintain voltage stability. Temperature management is also an important aspect because temperature increases due to high loads can accelerate insulation degradation and reduce the life of transformers. Efficient cooling systems, such as oil or air cooling, are often used to solve this problem. Real-time condition monitoring and preventive maintenance can help in detecting and addressing problems before they become serious. With a comprehensive analysis involving load studies and operational simulations to predict the performance of transformers under various conditions. This helps in designing better transformers and determining optimal operating strategies to improve the efficiency and reliability of transformers.

Organisational resilience to GPU side-channel attacks has surfaced as a pressing requirement with the advent of high-performance computing and data-intensive applications. The increasing adoption of GPUs necessitates commensurate cybersecurity mechanisms to protect sensitive information and assure the proper functioning of computing components. This work investigates the implications of NIST’s Cybersecurity Framework 2.0 within risk management and governance considering GPU side-channel attacks. We provide an overview of prevalent threats against GPU accelerator systems in terms of timing attacks, power analysis as well as cache attacks. Subsequently, a dependable, secure shader execution architecture is specified based on current state-of-the-art solutions augmented by advanced mathematical formulas exploited to reduce risks caused by GPU side-channel attacks in practice. In this context, we show that resilience can be reached, especially when risk-aware management is combined with adaptive governance measures derived from NIST’s Cybersecurity Framework 2.0, processing regular updates quarterly or even more frequently using our methodology.

The migration from proprietary GPU drivers of Nvidia towards open-source for the R555-R560 series involves significant security, performance, and feature implications. In this paper, we present a new methodology to improve the security posture of open-source GPU drivers while ensuring optimal performance as well as full-feature support. We are particularly concerned with side-channel vulnerabilities that can be exposed during GPU operation.

It is normal practice to send and receive short messaging service (SMS) messages using a mobile phone. As a result, mobile phones are indispensable for the communication of information in a secure and instantaneous manner in our everyday lives. While utilizing mobile computing, this is one of the most efficient techniques for exchanging data in a safe manner. These days, researchers are concentrating their efforts on mobile computing as a technology that can send data in a safe and effective manner. Ensuring that end users are able to communicate securely with one another from beginning to finish is essential for protecting against it. We propose a method that encrypts SMS data from the beginning to the end as it travels over the network in order to accomplish the above-and-beyond. In addition to being an effective and safe protocol, EasySMS makes it possible for end-to-end encrypted SMS communication to take place between end users. The implementation of this protocol is the objective of this endeavor.Two mobile stations, the authentication server (AS) and the relevant mobile station (MS), are responsible for storing all of the symmetric keys that are shared between the AS and the MS. The registration authority is responsible for storing all of the information that is associated with the mobile subscriber. Simply said, these are the primary elements that make up the Easy SMS system.The only thing that happens during the first step is authentication, but during the second stage, the two mobile phones really communicate with one another in order to send and receive messages before the time limit is approached.Two different scenarios are included in the Easy SMS protocol.In the first scenario, both mobile stations are connected to an authentication server (AS), which is required for authentication.When it comes to the second scenario, the mobile stations make use of two distinct authentication servers (AS).A number of different encryption methods are used while transmitting data over the short message service (SMS). These methods include the Advanced Encryption Standard (AES), Triple DES, and the MD5 algorithm, which provides a hash function.The Easy SMS protocol offers protection against a variety of threats, including impersonation, replay, man-in-the-middle, over-the-air modification, and SMS disclosure, to name a few.

The cloud is extensively utilized, yet it comes with its own set of concerns and threats to users' privacy. When compared to more conventional computer frameworks, the shared computing infrastructure known as the cloud presents a significant number of security vulnerabilities. It is never feasible to have complete faith in the cloud provider or tenants who store their data in a shared environment since there is always the possibility that they may leak data at any point of the compute process. Because of these problems with cloud computing, there is a requirement for a secure framework to carry out analytics activities, and cryptographic tools need to be developed in order to safeguard sensitive data while it is being stored and while it is in transit. The majority of companies have a dilemma when it comes to protecting large amounts of data while it is being stored.

This research paper presents an innovative approach to object detection in drones utilizing the HB100 radar module. The primary objective of this study was to develop a system capable of capturing both stationary and moving objects, regardless of the visibility conditions in the surrounding environment. By integrating the HB100 radar module into the drone’s architecture, real-time object detection and tracking capabilities were achieved, significantly enhancing the drone’s perception abilities. The experimental setup involved integrating the HB100 radar module for a quad-copter drone external platform linked to the base station; enabling the collection of radar signals and subsequent processing for object detection. Various stationary and moving objects were employed to evaluate the effectiveness of the system under different environmental conditions, including scenarios with limited visibility, such as fog or darkness and power-bandwidth. The HB100 radar module operates based on the principle of Doppler radar. It emits continuous wave (CW) signals and detects the Doppler shift in the reflected signals to 1(zero crossing).

The changing to standing wave in a reflecting wall distance or determine the presence and movement of objects. The safety and mine hazard conditions the flooding and double differentiating checks it accelerating values on positive and negative sides forming colored pattern of moving directional object movement. The phase patterns of these images are the region of convergence using Z transform on those images changing values to spirals. Lastly, the issues of whole setup is tested with load balancing on both on weight and electric circuits DC due to not operating shunting based on electron discharge phenomenon in any environmental conditions.

As a key technology for remote sensing applications, Synthetic Aperture Radar (SAR) offers high-resolution images for a range of Earth observation uses. In order to improve picture interpretation, feature extraction, and information retrieval, this work explores the incorporation of phasor mapping approaches into SAR data analysis. The first section of the study explains the basics of SAR and the difficulties in deciphering complicated SAR images. The introduction of phasor mapping presents a potent tool for streamlining the analysis and representation of SAR signals, allowing for a more intuitive comprehension of amplitudes, phase correlations, interferometry and polarimetric data. Phasor mapping is a crucial method used in Synthetic Aperture Radar (SAR) to handle complex-valued radar information. Radar pulses are first sent in the direction of the earth, and the backscattered signals that arise are gradually sampled. After enhancing the signal for better resolution using range compression, the SAR signal is represented as complex phasors. The amplitude and phase information of the received signals at certain spatial locations are captured by these phasors. Each pixel in the SAR picture is given a phasor using phasor mapping, which converts the complex-valued data into a visual representation. With the phase information being especially useful for applications like interferometry for Digital Elevation Models (DEMs) and terrain motion detection, the generated pictures provide light on the scattered distribution on the ground. In the end, phasor mapping is essential to deriving valuable insights from SAR data, paves a way of multitude possibilities for geospatial research and remote sensing applications. We provide a graphical user interface (GUI) and performance enhancing Ashmit transform 2 post processing step. The visual light provides an eye on path contained with stones (dihedrals), mud-water (volume scattering) and table top flat modulation or path (surface scattering). But our motivation on dihedral and volume scattering in InSAR and MRIs. So phase unwrapping or phasor mapping is an indispensable for radiologist or geologist. The GUI of phase unwrapping and Ashmit transform 2 post processing helps to detect the radio transceiver in pixel range hence in medical, military, and civil services, it is a good modular change.
