Security is one of the main considerations in choosing file storage media. Cloud server is one of storage mediums that provides virtual resources to users through third party and it can be accessed through the Internet connection. Cloud computing has several advantages, such as ease to access, ease to control, user-friendly to operate, and flexible capacity. However, these advantages cause potential security problems such as data breach attack. Therefore, a strong security system becomes important to overcome the losses caused by these security problems. A solution to increase the security level is utilizing cryptography algorithms. Due to the discovery of several loopholes in the traditional cryptosystems, the concept of using Computational Deoxyribonucleic Acid (DNA) cryptosystem was identified as a possible more complex cryptosystem to solve. Meanwhile, Role-based Access Control (RBAC) provides efficient and strong ways to manage authorization of the system resources based on user authentication. By cooperating with Identity-based Cryptography (IBC) and DNA cryptosystem, we propose an efficient authentication system to securely access electric vehicle (EV) data stored in the cloud server based on identity-based RBAC.

Indonesia is a significant palm oil producer, widely cultivated due to its status as a prominent vegetable oil-producing plant. Palm oil is a highly sought-after crop in agriculture due to its profitability and the demand for substantial quantities of high-quality oil. Early diagnosis of oil palm diseases is crucial for prompt prevention and eradication measures essential for maintaining high-quality palm oil production. Hence, there is a requirement for a machine vision-based method to classify diseases on plant stems. The proposed method consists of several main processes: pre-processing, feature extraction, and classification. Several machine learning algorithms and feature extraction using color and texture features were performed to develop a machine vision for detecting oil palm stem disease. It applied cross-validation with a K-fold value of 10. Performance evaluation was carried out using three parameters: precision, recall, and accuracy. The Linear Discriminant Analysis (LDA) method achieves the optimum results in testing scenarios combining color features based on HSV color space and textures features, achieving an accuracy value of 90.50%. © 2023 IEEE.

Ahstract-Zero-shot text classification leverages pre-trained transformer models to categorize texts without the need for task-specific training. This paper analyzes a variety of transformer-based pre-trained methods on the task of zero-shot text classi-fication. Specifically, we present a deep comparative analysis of various transformer models, such as BART, DeBerta, DistiIBART, RoBERTa, and their variants, and evaluate their performance in various zero-shot text classification schemes. Furthermore, we examine the models' generalization capabilities. The findings highlight key strengths and weaknesses of each model, providing insights into their suitability for different text categorization tasks. Our research contributes to the broader understanding of transformer-based approaches and offers guidance for selecting models for zero-shot text classification.

In this paper we study a mobility-aware call admission control mechanism applied in a mobile hotspot. We consider a vehicle, which can alternate between stop and moving phases and has an access point of a fixed capacity. In the stop phase, the vehicle accommodates both new and handover calls. To prioritize handover calls a probabilistic bandwidth reservation (BR) policy is applied where some of the system's resources are reserved for handover calls. Based on this policy, new calls may enter the reservation space with a predefined probability. In addition, handover calls can wait in a queue of finite size if there are no available resources at the time of their arrival. In the moving phase, the vehicle services only new calls under the probabilistic BR policy. In both phases, arriving calls follow a Poisson process, require a single bandwidth unit from the system and have an exponentially distributed service time. To analytically determine the most significant performance measures such as call blocking probabilities an efficient iterative algorithm is presented. © 2022 IEEE.

Recent years have witnessed many advancements in the applications of 3D textured meshes. As the demand continues to rise, evaluating the perceptual quality of this new type of media content becomes crucial for quality assurance and optimization purposes. Different from traditional image quality assessment, crack is an annoying artifact specific to rendered 3D meshes that severely affects their perceptual quality. In this work, we make one of the first attempts to propose a novel Perceptual Crack Detection (PCD) method for detecting and localizing crack artifacts in rendered meshes. Specifically, motivated by the characteristics of the human visual system (HVS), we adopt contrast and Laplacian measurement modules to characterize crack artifacts and differentiate them from other undesired artifacts. Extensive experiments on large-scale public datasets of 3D textured meshes demonstrate effectiveness and efficiency of the proposed PCD method in correct localization and detection of crack artifacts. Moreover, to quantify the performance of the proposed detection method and validate its effectiveness, we propose a simple yet effective weighting mechanism to incorporate the resulting crack map into classical quality assessment (QA) models, which creates significant performance improvement in predicting the perceptual image quality when tested on public datasets of static 3D textured meshes. A software release of the proposed method is publicly available at: https://***/arshafiee/crack-detection-VVM

This study explains the simulation design and working principle of unipolar inverters on grid using the current control method using PSIM software. The inverter circuit used is a full bridge inverter circuit using a current control method. The series of filters used is a low pass (LC) filter using an L value of 4.06 mH and a C value of 6.23 μ F. The control circuit used is an SPWM (Sinusoidal Pulse Width Modulation) circuit. The power supplied by the inverter to the grid is affected by the magnitude of the angle, voltage, and the same frequency. The power supplied by the inverter to the grid based on the reference of the control system will run if the angle phase between the inverter and the grid is the same. The grid will accommodate the excess power generated by the inverter and will also supply power if the inverter is under-powered from the solar power plant source. This study also aims to regulate the power required at the load, hence the power supplied to the optimal load, with the main supply coming from the inverter and the lack of power supply can be seconded by the grid from PT. PLN (State Electricity Company). This is shown when the reference current is set at 4 A, the current required load is 5.65 A, where the inverter supplies current to the load by 3.44 A, and the lack in supply from the grid is 2.207 A. The frequency value on the system is constant at 50Hz. The current control method aims to make the current supplied to the load obtained by setting the priority scale of the current supply, where the inverter current is the main current source and the grid as the secondary supply. © 2022 IEEE.

The development of Virtual Reality technologies has improved people's daily lives in many sections. Nowadays, it is applied in fields such as Health, Work, Telecommuting and in a large number of other sectors. Education from different perspectives is something that constantly concerns researchers and virtual reality developers, which is why we come across a series of virtual reality applications for situation simulation and student education. Mathematics and especially geometry which is interrelated with the concept of the implementation of applications in three-dimensional space, as well as VR applications, from the perspective of learning are often considered complicated as there are three-dimensional objects that are not easily perceived only through a book. In this paper we examine how through virtual reality geometric concepts can be better understood but at the same time to examine geometric shapes from different angles and perspectives. © 2022 IEEE.

Collecting data for various parameters in the agriculture domain aims to help farmers and agronomists to take proper decisions regarding the health and the status of the cultivation. Mushrooms are becoming one of the most valuable ingredients in nowadays diet, giving additional vitamins and flavour without sodium or fat. Moreover, various mushroom species can grow in greenhouses under restricted controlled conditions. Furthermore, atmospheric parameters in the greenhouse and parameters from the substrate are of paramount importance in mushroom cultivation. Therefore, measuring and controlling these parameters using modern approaches based on Internet of Things technologies might leverage production. In addition, a decision support system based on aggregated data can help mushroom farmers in everyday decisions. In this manuscript, we propose a system architecture for data acquisition and decision-making for a greenhouse with mushrooms based on innovative technologies. Besides, we provide directions for wild mushroom hunting based on UAVs and sensors deployed in forests. © 2022 IEEE.
