The investigation of resonant circuit parameters influence on the control characteristics behavior in a boost half-wave zero-current switching quasi-resonant converter is presented. The dependences of the control pulses duration and operating frequency as well as electric characteristics under variation of resonant circuit time constant and control pulses duty cycle are established by the numeric simulation and are represented as 3D-surfaces. The dependences of these characteristics under variation of load impedance and control pulses duty cycle are also obtained. The obtained results can be used in the process of developing and constructing a table-based, robust multi-loop or nonlinearity compensated control systems for quasi-resonant converters. © 2023 IEEE.

Grasp coordination is crucial for performing cooperative object manipulation tasks. Planning cooperative grasps among a group of decentralized robots is a new line of coordination problem that requires robots to simultaneously handle complex and large shaped and sized objects, a new level of difficulty that is rarely addressed in the literature. In this paper, we propose grasp coordination approaches for a decentralized group of robots facing explicit communication and sensing limitations. In particular, a scenario where robots with incomplete knowledge about each other's embodiments further lose the ability to 1. observe others' grasps occluded by the object's shape 2. exchange direct messages due to potential communication degradation resulting from the real-time planning and execution constraints. To tackle such a scenario, we introduce two baseline and two probabilistic approaches that are specifically designed for strict decentralization. The approaches analyze cooperative grasps using traditional grasp quality metrics and estimate cooperative grasps based on the assigned robot's priority. Simulation experiments demonstrate that the probabilistic approaches exhibit superior performance over the baseline approaches, reaching performance close to optimal for both homogeneous and heterogeneous groups. These approaches provide solutions to simulated multi-robot grasp coordination scenarios that have the potential to translate to real-world environments such as logistics, manufacturing, and services. © 2023 IEEE.

Task allocation is a significant topic in the field of artificial intelligence, and ideas for solving this problem are often drawn from the widespread phenomenon of division of labor in nature. For the problem that the existing labor division game model does not match the characteristics of the large-scale division of labor scenarios, We propose a new model named division of labor within community game(DOLC). The article establishes the mathematical model of DOLC, then we investigate the effects of selection intensity, urgency coefficient and responsibility coefficient on the evolution of division of labor. We derived the following conclusions: When both urgency and responsibility coefficients are zero, this causes the tragedy of DOLC, while group has the opportunity to maintain the division of labor if one of them is positive. The responsible group has always been cooperative. Relative to urgency coefficient, responsibility coefficient plays a more noticeable role in facilitating the evolution of cooperation in population. DOLC model is well suited to task allocation problem in multi-agent systems, and the findings of this article provide new insights for improving the intelligence of unmanned systems and optimizing task allocation and scheduling. © 2023 SPIE.

In this paper, we focus on the follicular unit registration problem for hair transplantation surgery robots based on binocular stereo vision system. The follicular units in both images are detected with YOLO V5 network. Because of the dull and similar pattern of the follicular units, previous regular methods which are pixel-based are reported with misalignment and poor accuracy. To solve this problem, we propose the context shape to describe the feature of the follicular unit. The distribution of units surrounding the target unit is estimated as the context shape. Then, Otsu's method is used to segment hairs and Hungarian algorithm is used to match the hairs in the matched follicular unit. Then, the hairs are projected to 3D coordinate system and reconstructed. The experiments on the generated hair dataset demonstrate that the proposed method achieves both high accuracy and speed. © 2023 IEEE.

Ternary logic is popular where it uses logic levels of 0, 1 and 2 instead of using the old binary logic structure. Due to this, it has grown to be very popular method in many applications. It is used in applications which focuses on high density data processing and also to obtain lower power consumption. The design of this SRAMs poses lot of challenges and there is a high demand for robust and optimized memory units. This work concentrates on overcoming the problems of higher power consumption that is found in traditional SRAM cells. It focusses on the comprehensive study if 6T, 8T and 10T SRAM cells. Through this study, the performance metrics are analyzed for power consumption and R/W efficiency. The results obtained shows the lower consumption of power and improved R/W efficiency. © 2024 IEEE.

The inspiration that drives this study is the increase in the prevalence of misinformation, and the need to solve the big challenge of detecting fake news. With the possibility of uncontrolled misinformation disastrously impacting our society, the objective of our study is to make contributions towards the body of knowledge which aims to improve the efficiency and accuracy of current methodologies to detect false information. Although there has been an improvement in the fake news detection systems, their adaptation to real-time applications remains sub-optimal due to the subtle and complex processing involved with handling misinformation. The purpose of this study is to bridge this gap and come up with a better detection model using the Recurrent neural network (RNN) models like Long Short-Term Memory (LSTM) and Bi-directional LSTM (BiLSTM) that will enhance the performance of the existing models, especially in terms of detection accuracy, as the existing systems are weak in the 'disagree' category and mostly misclassify it. We use a mix of machine learning algorithms and natural language processing techniques. Integrating LSTM with BiLSTM will analyze textual content at a granular level to find patterns representing fake news. The preliminary results have indicated that our model is performing significantly better than existing ones, with an overall improvement of up to 86.25% in accuracy [15]. However, in the 'disagree' category, there are a few challenges faced by the system, reflecting the scope for many improvements in the future. Our research has made a valuable contribution to the knowledge and tools in the area of digital information credibility by providing a strong model that improves detection rates of more subtle cues of misinformation thereby, combating the spread of fake news. © 2024 IEEE.

Strict adherence to pollution limits poses a risk to light-duty diesel engines due to challenges in post-treatment procedures, product limitations, and emission criteria. This paper aims to determine the underlying principles for the technological development of an after-treatment technique that incorporates a diesel oxidation catalyst (DOC), catalytic Diesel Particle Filter (DPF), urea injector, and catalytic urea selective reduction (SCR). Implementing this selective catalytic reduction (SCR) technique would greatly enhance the catalyst's ability to convert NOx by regulating the evaporation of urea and avoiding a decrease in exhaust temperature and mixing efficiencies. Moreover, the uniformity of the NH3 concentration distribution over the catalyst surface is advantageous. This study explored the concept of an electrically evaporated urea-dosing device. The investigation revealed that heated urea had a beneficial effect on improving the elimination of NOx from both continuous and intermittent motor operations before its application to the gas exhaust. The cylindrical urea evaporative heating chamber was equipped with a venturi jet that directed urea vapour down the exhaust drain. The urea solution dosing technique, administered by spraying, was a customised method more advantageous than the conventional liquid dosage system. © 2024 Institute of Physics Publishing.
