Authorship attribution (AA) is a subfield of NLP that analyzes the author's prior works to determine who wrote a text based on its features. Each natural language has its characteristics, just like every author's unique writing style. This study aims to conduct an in-depth comparison of several AA machine-learning techniques. The specially created Albanian corpus (A3C) and the English dataset (Reuters C50) have been used in the experiments. Using n-grams, we perform character-level and word-level analyses of the text to represent the author's writing style. We use five different classification algorithms to train the AA models. The TF-IDF feature vector is used as input to the models. Various experiments were conducted on the corpora. The most accurate results were obtained using word n-grams after stopword removal. The SVM algorithm performed best on the A3C dataset (Albanian). We get a 95% F1 score using SVM. On the C50 dataset (English), the SVM classifier achieved an 83% F1 score. Experiments have provided evidence of the models' robust performance on the AA corpora.

Malicious attackers are constantly attacking software compilers and attempting to exploit various security vulnerabili-ties. By executing carefully chosen machine instructions already present in the program, an attacker can perform harmful actions arbitrarily. In this paper, we propose hardware/software codesign techniques to perform software compilation steps in hardware, specifically the register allocation step on a Field Programmable Gate Array (FPGA). Our experiment incorporates two key features: 1) Advanced RISC Machine (ARM) instruction set architecture (ISA)-based register allocation algorithms to calculate variable liveness as well as map virtual registers to physical registers and 2) the feasibility of executing the register allocation algorithms on a Cyclone V FPGA. Our experimental results show the timing efficiency and resource efficiency - while diminishing security risks - when performing register allocation of the gcd program on the FPGA.
恶意攻击者不断攻击软件编译器并试图利用各种安全漏洞。通过执行程序中已经存在的精心选择的机器指令，攻击者可以任意地执行有害的操作。在本文中，我们提出了硬件/软件协同设计技术来执行硬件中的软件编译步骤，特别是在现场可编程门阵列(FPGA)上的寄存器分配步骤。我们的实验包含两个关键特征:1)基于高级RISC机器(ARM)指令集架构(ISA)的寄存器分配算法，用于计算可变活度以及将虚拟寄存器映射到物理寄存器;2)在Cyclone V FPGA上执行寄存器分配算法的可行性。我们的实验结果表明，在FPGA上执行gcd程序的寄存器分配时，时序效率和资源效率-同时降低了安全风险。

A frequency synthesizer is an electronic circuit that generates a desired frequency from a single reference frequency or several reference frequencies. In this paper, a new simple frequency synthesizer is described, which will make it possible to generate a signal at the output whose frequency is the sum of the frequencies of the input signals divided by a constant. The results of the synthesizer simulation are presented in this paper. The synthesizer was not only simulated, but actually implemented by a microcontroller, and the measurement results are also presented. The main advantage is that the synthesizer can be created by programming in any microcontroller.

With the increase of Internet of Things (IoT)-based platforms in different fields such as smart grids, cities, manufacturing, transportation, and healthcare, data collection and processing techniques have become more important, as their effectiveness impacts the performance of the overall system. In this paper, the IoT-based smart city platform, called OpenCyberCity, is evaluated in terms of scalability, reliability, and latency with millions of virtual IoT devices in a simulated environment. In order to improve the efficiency of these three parameters, the architecture suggests taking advantage of the MQTT protocol, Kafka data streaming, and Cassandra database, which are combined with a high-level program that is responsible for maintaining collaboration between them. According to the results, the proposed architecture can support at least one million IoT devices with 100% reliability for smart cities under the simulation environment.

In the last few months we see the increased use of AI system in all aspects of live, including the education. Changes are seen in the IT business, ordinary business and introduce a plethora of problems into education. The AI can be absolute personal assistance if used correctly or a hell for learners and teachers if misused. On the other way it is so easy to misuse it and too time consuming to prevent these activities. The previous thought: Who will teach the teachers, is more and more important as the AI literacy of all involved in education must also incorporate the ethical consideration of application of AI in the education. We are trying to present the ethical codes that include AI and four basic building blocks of the ethical attitude of AI in education (autonomy, privacy, trust, and responsibility). Understanding the concepts of AI and their ethical considerations is a condition for acting in accordance with them and for introduction them in education.

The problem of forming a radar radiation pattern with a sparse linear antenna array is considered. Sparse structures based on the combination of homogeneous co-prime linear arrays are investigated. The method of forming virtual structures is explained. Using concrete examples, the shape and properties of the side lobes of the amplitude radiation pattern are investigated. The amplitude radiation patterns of two sparse arrays with the same number of physical elements and a conventional antenna with a phased array (FAR) are compared.

Prevention of emergencies associated with flammable gases explosions remains an urgent task. A ranking place in solving of this task plays environment monitoring for combustible gases presence. The environmental explosiveness level can also be assessed overall, without measuring separate gases concentrations. The assessment of environmental explosiveness level can be performed using catalytic gas sensors based on combustion heat measurements of flammable gases combustion in the sensors. Modern data processing methods application, such as machine learning, allows to increase the measurements accuracy. However, machine learning needs a Iot of data. To collect that data enough measurements for different gases should be performed. At the same time, the question remains of whether it is possible to apply the machine learning models to gases, which have not been used while training. In this work, the results of the research are presented, where the possibility of successful models training using limited gases set and the ability of such models to assess the explosiveness level of other gases and mixtures were examined.

Nowadays, embedded systems are ubiquitous and their functionality is becoming increasingly intertwined with various critical demands. Integrating functionality with different criticality demands has led to the emergence of mixed-criticality systems (MCS), which require adaptive fault tolerance to ensure the correctness of critical tasks. In this paper, we propose a hardware-based adaptive redundancy approach for multi-core systems, which aims to enhance the reliability and safety of MCS. Our approach involves the reconfiguration of two physical processor cores into a single logical core that executes the same program on demand. The logical core provides adaptive redundancy to detect and mask faults. However, this reconfiguration can potentially result in deadlocks. To address this issue, we identify the scenarios where deadlocks may occur and provide a countermeasure to prevent their emergence. By adopting this runtime adaptive and hardware-based adaptive redundancy method, we can improve the reliability and safety of mixed-criticality systems. At the same time we utilize the processor architecture to abstract the reconfiguration process.

Sensors based on chaotic oscillators comprise a promising direction in the field of nonlinear dynamics. Hypothetically, such sensors have improved sensitivity, selectivity, and rate. In this paper, we research and develop an inductive sensor based on the Sprott Case B chaotic oscillator, which features a double-scroll attractor. We propose a circuit implementation with inductive coil, and compare the results of the computer simulation with experimental study. We conclude that the proposed circuit is suitable for use as a limit switch to determine the position of a steel plate, as its dynamics is switching from chaotic to periodic regime at a certain adjustable distance between a coil and the plate. The performance obtained in the study is comparable with sensors of conventional design, but has the potential for improvement.
