Implantable cardiac devices (ICDs) are often used as an effective treatment for arrhythmia. Although these devices have access to a live Electrocardiogram (ECG) stream, currently they do not offer on-device classification of arrhythmia due to the limited computing capability and severe power constraints. In this paper we propose a low-energy computing method for extracting shape-based features from ECG in combination with machine learning techniques for classifying nine different cases of arrhythmia. This is achieved by using a Localized Longest Common Subsequence (LLCS) algorithm which has low computational requirements that allows on-device execution. The proposed method strongly focuses on maintaining minimal energy and computational footprint, in line with the operating constraints of implantable devices. To demonstrate the energy efficiency and low computation load of the proposed method we implement the classification pipeline on a low-power RISC microcontroller and compare its performance with existing classification techniques. The classification accuracy and energy of the proposed method is compared with state-of-the art research in arrhythmia classification.

We study age of information (AoI) in a status update system for the generate-at-will (GAW) scenario, consisting of a single information source, dual heterogeneous servers, and a monitor. For this system, stochastic hybrid systems (SHS) were used to obtain the mean AoI for the work-conserving zero wait (ZW) policy with out-of-order packet discarding at the monitor. In this paper, we propose a non-work-conserving freeze/preempt (F/P) policy for which the sampling and transmission process is frozen for an Erlang-distributed duration upon each new transmission, and out-of-order (obsolete) packets are preempted at the source, rather than being discarded at the monitor upon reception. We use the absorbing Markov chain (AMC) method to obtain the exact distributions of AoI and also the peak AoI (PAoI) processes, for the F/P policy. Numerical results are presented for the validation of the proposed analytical model and a comparative evaluation of ZW and F/P policies.

In this paper, the modified form of well known heuristic PSO search algorithm known as fully informed PSO (FIPSO) algorithm is proposed to optimize the energy and cost to reduce the frequent fluctuation of energy sources output in a microgrid. The conventional PSO suffers from the premature convergence that limit the energy optimization and cost reduction. The effectiveness of the suggested FIPSO algorithm is contrasted with the conventional PSO and it is noticed that the suggested algorithm outperforms the existing method. Several computer simulations have been performed using Matlab environment to investigate the performance of the energy sources with and without optimization algorithm.

According to the conditions of the present era and the importance of electricity in our world, it is felt more moving towards applying of new and technological methods to produce this energy in cleaner and more economical way and investing in this sector. Distributed Generations as one of the main solutions for this aim have been considered by energy policymakers in countries. Distributed generations that restructure the power system and reduces centralization in power generation are usually used in a new structure called a microgrid. The microgrid is one of the main components in the smart grid subset, which is a grid with new telecommunication technologies, measurement and energy production. A very important issue in microgrids is the optimization of investment required to create microgrids and costs over the life of the project by considering the required elements and infrastructures. In this dissertation, by considering two interacting microgrids that are adjacent to each other, the issue of optimizing the size of their components using particle swarm optimization (PSO) algorithm and using an intelligent multi agent system in each microgrid has been investigated. The simulation results of both interactive microgrids, which are the optimal size of their components and the optimal cost of creating each microgrid, have been obtained and examined using MATLAB software.

This study presents the development and implementation of a sophisticated Web Application Firewall (WAF) empowered by machine learning techniques to bolster cybersecurity measures. Traditional WAFs primarily rely on rule-based systems, which may struggle to adapt to the evolving nature of web-based threats. In contrast, our proposed solution leverages machine learning algorithms to dynamically analyze and respond to emerging cyber threats, providing a more proactive and adaptive defense mechanism. The core functionality of the system involves the continuous monitoring of incoming web traffic, extracting relevant features, and utilizing a machine learning model to classify the traffic as either benign or malicious. The model is trained on historical data to recognize patterns and behaviors indicative of various cyber threats, including SQL injection, cross-site scripting, and other common attack vectors. Through this learning process, the system becomes adept.at discerning malicious activities and adapting its defense strategies accordingly. The proposed model helps achieve higher precision in identifying the threat requests from normal requests.
