Self-sustenance of India in oil and coal has consistently turned down, so electric vehicles are the future need of the society and environment. The heart of an electric vehicle is a battery; its degradation and safety are prime important issues to avoid accidents. Therefore, setting such a mechanism that improves the performance of a battery is a requirement of the society. The main objective of this article was to compare various aging parameters of a battery used in the electric vehicle, in terms of their effects, monitoring methods, and benefits for battery aging. It also aimed to illustrate the information out of touch that can be used for future research. This helps to maintain the clean environment by reducing pollution and economical benefit to the society.

Visualization is primarily utilized as a training method to enhance athletic movement quality, increase concentration power, and minimize competition stress on the player while building firm confidence. Physical literacy (PL) provides a valuable lens for analyzing physical activity (PA) movement in more significant social and affective learning processes. This paper presents an Interactive Visualization positioning in physical education (IVPPE) to deal with the signal fluctuations and positioning techniques in visualizing Deep Neural Network (DNN). To ensure the success of their game, athletes are always looking for new ways to improve their health and performance. Using sensors to keep tabs on training and recovery has become more popular among athletes. Currently, sports teams are using sensors to track both the players’ internal and external workloads. It illustrates the multilayer localizer (MLL) based on transfer learning to improve the positioning accuracy and physical literacy positioning model (PLPM) as a health determinant. A variety of data augmentation techniques are used to combat signal fluctuations. As a result, the combined effects of motivation-promoting physical activity-based visualization improve the accuracy ratio to 96.7%, prediction ratio to 96.2%, efficiency ratio to 96.8%, and reduce the error rate to 18.7%, stress level (52.8%) compared to other conventional models and have a positive impact on the localizer and positioning, making a difference in physical activity (PA) levels.

This paper proposes an energy efficient approach for securing inter-connecting IOT devices with servers. A scheme using blockchain and a second network for security management was previously described [1]. To overcome the drawbacks and shortcomings of using traditional smart contract with Ethereum, a new approach is proposed. The proposed approach ensures that the overall IoT network is “hardened” against attack using a framework which is environmentally sustainable and meets the stringent requirements of mission critical applications. This new approach also results in shorter latency, higher throughput and consuming less power, thus suitable for edge computing environment in mobile.

This paper discusses commonly used reverse engineering methods to illegally recreate printed circuit board (PCB) designs. A solution using transformative electronics is presented to prevent the discussed reverse engineering methods by obfuscating the design. The transformative electronics solution is employed in a specific application that results in a reverse engineered board to be incorrectly recreated, where the signals would be distorted due to added electromagnetic interference (EMI). The non-conductive vias that are part of the obfuscation would allow the inclusion of EMI generators that would not affect the circuit in an original design but would prevent copied designs from working correctly. A machine learning algorithm is being designed to optimize the placement of the EMI sources in an original PCB.

The recent advance of artificial intelligence (AI) has shown remarkable success for numerous tasks, such as cloud computing, deep-learning, neural network and so on. Most of those applications rely on fast computation and large storage, which brings various challenges to the hardware platform. The hardware performance is the bottle neck to break through and therefore, there is a lot of interest in exploring new solutions for computation architecture in recent years. Compute-in-memory (CIM) has drawn attention to the researchers and it is considered as one of the most promising candidates to solve the above challenges. Computing-In-memory is an emerging technique to fulfill the fast-growing demand for high-performance data processing. This technique offers fast processing, low power and high performance by blurring the boundary between processing cores and memory units. One key aspect of CIM is performing matrix-vector multiplication (MVM) or dot product operation through intertwining of processing and memory elements. As the primary computational kernel in neural networks, dot product operation is targeted to be improved in terms of its performance. In this paper, we present the design, implementation and analysis of quantum-dot transistor (QDT) based CIM, from the multi-bit multiplier to the dot product unit, and then the in-memory computing array.
人工智能最近的发展在云计算、深度学习、神经网络等众多任务中取得了显著的成功。这些应用大多依赖于快速计算和大存储,这给硬件平台带来了各种挑战。硬件性能是突破的瓶颈,因此,近年来人们对探索计算架构的新解决方案非常感兴趣。内存计算(CIM)已经引起了研究人员的注意,它被认为是解决上述挑战的最有前途的候选者之一。内存计算是一种新兴技术,旨在满足对高性能数据处理快速增长的需求。这种技术通过模糊处理核心和存储器单元之间的边界来提供快速处理、低功耗和高性能。CIM的一个关键方面是通过处理和存储元素的交织来执行矩阵向量乘法(MVM)或点积运算。点积运算作为神经网络的主要计算核心,其性能有待提高。本文介绍了基于量子点晶体管(QDT)的CIM的设计、实现和分析,从多位乘法器到点积单元,再到内存计算阵列。

QDG-SRAM Simulation Using Physics-Based Models of QDG-FET and QDG-Inverter 基于QDG-FET和qdg -逆变器物理模型的QDG-SRAM仿真

This paper investigates the underlying physics of a SRAM device utilizing three-state Quantum Dot Gate (QDG) FETs by building up the physics from the general QDG-FET, its relation to the QDG-Inverter, and ultimately, the QDG-SRAM. The resulting equations from the exploration of the device physics were utilized to create a simulation within SIMULINK. From the simulation, it was found that in addition to being able to store the “1” and “0” states that are customary for an SRAM device, there is also the ability to store an intermediate state and a pseudo-state as a result of the intermediate state, allowing for the possibility of a 2-bit SRAM device in the same spatial constraints of a conventional SRAM unit cell. Additionally, the experimental results of the QDG-SRAM half-cell and the implications of utilizing a 4 state device to create either a 4 state SRAM cell or a 6 state SRAM cell with two pseudo-states are also discussed.
本文研究了利用三态量子点门(QDG)场效应管的SRAM器件的底层物理,从一般的QDG- fet,它与QDG-逆变器的关系,以及最终的QDG-SRAM建立物理。从设备物理探索得到的方程被用来在SIMULINK中创建一个模拟。从模拟中,发现除了能够存储SRAM设备习惯的“1”和“0”状态外,还能够存储中间状态和中间状态的伪状态,从而允许在传统SRAM单元单元的相同空间约束中存储2位SRAM设备的可能性。此外,还讨论了QDG-SRAM半电池的实验结果,以及利用4态器件创建4态SRAM电池或具有两个伪态的6态SRAM电池的意义。
