Chatbot technology is considered one of the latest artificial intelligence tools used to achieve interaction between the organization and the customer. It relies on natural language processing, as it helps the organization know the desires and needs of the customer, in addition to collecting customer data and displaying the services provided by the organization. This research proposes an architectural model for supporting chatbots based on the ChatGPT model. It receives customer interaction inputs, understands questions, and responds quickly and appropriately. In addition, this model was designed and implemented using the Voiceflow platform. This model was named EDUBot to build communication elements and components to customize the structure of the virtual conversation and manage the dialogue. This model can be applied to the Educational City institution as a case study to improve customer service and help the institution manage customer relationships more efficiently. © 2024 IEEE.

Long Range Wide Area Network (LoRaWAN) is a wireless communication protocol that facilitates efficient and wide-range communication under low-power conditions. Over-the-air activation (OTAA) is a process recommended by Lo-Ra Wan v1.0.4 (latest version) that enables end devices to join the network with the help of the joining server and generate the session keys for further communications. However, OTAA is vulnerable to potential security threats due to unencrypted join request messages and the reuse of the same encryption keys. In this paper, we present a new security enhancement that addresses the aforesaid security issues. In the proposed scheme, we encrypt the join request message using a secret key to ensure data confidentiality. In addition, we incorporate the use of a random nonce in the proposed joining procedure to protect LoRaWAN against attacks related to the reuse of the same key. We show that the adversary cannot learn sensitive information from the join request message and reuse the AppKey to execute the eavesdropping and unauthorized activation attacks with non-negligible probability.

Qualitative approach for automated grading and quality assessment of fruits, machine learning techniques are crucial in agricultural applications. Automation enhances a nation's agricultural quality, production, and economic prosperity. Fruit quality grading, particularly the surface fault identification of a fruit, is a crucial indicator in the export market. This is particularly important for mangoes, which are quite well-liked inBangladesh. On the other hand, the physical grading of mangoes is a procedure that is labor-intensive, prone to error, and very subjective. In this paper, we proposed a YOLOv7 integrated Discrete wave transformation computer vision system. The proposed model includes support vector machine (SVM) and decision tree for the classification of high-quality mangoes. The results of the experiments show that the proposed solution obtained 96.25% accuracy when the system was trained and tested using a publicly accessible mango database. © 2023 IEEE.

With the explosion of data, Wireless Edge Caching (WEC) has become a promising approach for locally accessing cached contents. Due to the limited storage capacity of local caching devices and the varying preferences of humans for content, it is necessary to predict popular contents. In this article, we will address two distinct objectives: 1) Popularity prediction of the content that should be cached at the edge to effectively utilize edge device memory. 2) Edge devices collaboration for efficient content delivery. Accordingly, we propose an FL-based Star Cooperative Caching (FedStar Caching), utilizing a Star network topology for realizing an efficient cooperation among Femto-cell Access Points (FAPs) using a Decision Center (DC) to enhance power efficiency and delay performance. Considering human sensitivity to privacy, collecting users' data on a central server is not desirable, therefore, we leverage Federated Learning (FL) to alleviate this challenge. Simulation results demonstrate that the proposed method outperforms alternatives in terms of cache efficiency, as well as delay and power consumption. © 2024 IEEE.

Major Depressive Disorder (MDD) and Alcohol Use Disorder (AUD) are common neurological disorders that significantly impact physical health, family life, and work. Accurate diagnosis is essential for early intervention and treatment. However, conventional DSM-based diagnosis is subjective and susceptible to errors due to patient dishonesty or memory lapses. This study introduces a more reliable and objective diagnostic approach using effective connectivity (EC) from EEG recordings of 30 healthy controls, 30 MDD, and 30 AUD patients. EC, calculated via partial directed coherence, was used as input for an SVM model, achieving a peak classification accuracy of 95.3%, with perfect accuracy in the beta and gamma rhythms. These findings underscore EC’s potential as biomarkers for more accurate diagnosis and early intervention in neurological disorders. © 2024 IEEE.

A situation-aware wearable computing system is defined as a wearable device with the capability to perceive, comprehend, and project the situations occurring in the environment in order to adapt its behavior accordingly. For this kind of devices, the identification of complex situations related to the activities performed by users in various contexts is of great interest. This requires the capability to identify context states. A well-known technique for this task is the Context Space Theory (CST), which provides a multidimensional space representing contexts. Although powerful and lightweight, this technique has the drawback of requiring manual definition of such a space, a time-consuming process that involves domain experts. To address this issue, this work proposes a data-driven approach for defining context spaces in CST using kernel density estimation. This approach is compared with a state-of-theart expert-based CST technique and a fuzzy inference system for context representation, demonstrating superior performance on the Extrasensory dataset.

This paper puts forward a fractional order sliding-mode-assisted disturbance observer-based model-free control (FO-SAMDOMFC) methodology for fractional order system with disturbance. First, the system dynamic model is rewritten as a fractional order ultra-local model (ULM), and a SMADO is designed to estimate the lumped disturbance term. Then, A closed-loop control law is proposed on the basis of the ULM with the objective of guaranteeing the convergence of the tracking error. Next, a proof of the stability of the closed-loop system is given based on the fractional extension of Lyapunov's direct method. Finally, the simulation compared with other controllers based on MATLAB/Simulink is realized, and the simulation results validate the proposed method. © 2024 IEEE.

A specific characteristic of computer and communication networks is their limited ability to directly apply the "classical reliability theory"to determine their reliability. This necessitates the development and use of methods that combine the reliability characteristics of network elements with their functional characteristics. In most cases, this boils down to methods for determining the functional reliability of network structures, i.e., their ability to perform their assigned functions with a specified efficiency. Like the methods of classical reliability theory, these methods also need to possess a high degree of invariance. In this paper a method for solving such a problem is proposed, based on defining the term "information process"and determining the time for its execution, taking into account the reliability of the means implementing it. © 2023 IEEE.

In new computing architectures, data is outsourced and sensitive data becomes vulnerable in various areas. Owners must guarantee that their data are secure from breaches and unauthorized users and available anytime. Various techniques have been proposed to maintain a certain degree of privacy in the database and to allow efficient execution of queries on cloud computing. These methods cannot securely support queries over encrypted data without leaking private data. Therefore, in this paper, a secure technique was proposed for executing queries over encrypted data, and the proposed technique was based on the design of CryptDB. This technique eliminates the limitations of CryptDB to perform server-side computations on cryptographic data of different principles. The proposed technique attempts to overcome CryptDB's limitations by encrypting with different keys in multidimensional mode and running each query on the corresponding data encrypted by the same key. © 2023 IEEE.

Wearable smart devices are capable of capturing a variety of information from their users using a multitude of noninvasive sensing modalities. Using features from the raw measurements of wearable devices, sensor fusion enables us to obtain a holistic picture of the users' context and monitor their activity state with increased accuracy. Human activity recognition using noninvasive sensors allows us to capture the natural behavior of users in their day-to-day lives. This in-the-wild activity recognition, however, poses several key challenges that must be addressed to create effective classification models. The main challenges are class imbalance, uncertainty in classifier decisions, and large feature spaces. To address them, this study further explores a probabilistic sensor fusion method called Naive Adaptive Probabilistic Sensor (NAPS) Fusion. In doing so, we establish the viability of NAPS Fusion for natural human activity recognition using noninvasive sensing modalities. NAPS Fusion handles dimensionality reduction by creating reduced feature sets and mitigates the class imbalance issue through the use of Synthetic Minority Oversampling Technique (SMOTE). Moreover, NAPS Fusion addresses uncertainty in the decisions of classifiers using a Dempster-Shafer theoretic late fusion framework. Our empirical evaluation demonstrates that NAPS Fusion has broad applications beyond its original design for cognitive state detection. It outperforms similar decision level sensor fusion methods (late fusion using averaging, LFA, and late fusion using learned weights, LFL) in the detection of exercise and sedentary activities such as walking, running, lying down, and sitting. We observe improvements of up to 56% in F1 score and up to 59% in precision with NAPS Fusion over the compared methods. © 2023 International Society of information Fusion.
