    Implementation of The Weather Station Software on A Microprocessor Platform Using .NET Technology
    (Видавництво Львівської політехніки, 2023-02-28) Marii, Bohdan; Pavych, Tetyana; Paramud, Yaroslav; Lviv Polytechnic National University; MedBridge Inc.
    The article presents an implementation of the weather station software on a microprocessor platform using .NET technology. The system consists of a hardware module that collects weather data, a microprocessor platform that processes data, and a software application that visualizes and stores data. The software system is designed using the NET platform, which provides an environment for software de- velopment. The system uses a web interface that allows users to access the weather from anywhere with a web browser. The test results of the system demonstrate collecting, pro- cessing, and presenting the weather in real time. By compar- ing readings from AccuWeather with data collected by Ar- duino sensors, we ensure the accuracy of measurements. AccuWeather Europe is a source of weather data that can be used to validate weather information collected by Arduino sensors. In the developed systems, neural networks for weather forecasting are also used. The neural networks learn patterns and relationships in historical weather data to pre- dict future weather conditions.

    Embedded Systems Multimedia Framework for Microcontroller Devices
    (Видавництво Львівської політехніки, 2023-02-28) Krainyk, Yaroslav; Petro Mohyla Black Sea National University
    The presented paper attempts to establish a generalized approach to the development of embedded systems multimedia applications. It is formalized in the form of a framework that defines rules and recommendations for a developer on how to implement specific pieces of software that work with multimedia data. The basis for the development process is the division of the system’s functionality into stages with the following development of each stage. The framework also defines how touch sensor events may be elaborated. The proposed framework has been tested in a test scenario in an application with multiple stages. The results proved that the solution is feasible for multimedia applications (specifically, with graphics processing) and can be regarded as a generalized approach to the development of embedded systems with multimedia functionality.

    Enhancing SIM Card Technology: Developing an Advanced Operating System
    (Видавництво Львівської політехніки, 2023-02-28) Kose, Busra Ozdenizci; Sardag, Alp; Coskun, Vedat; Mantar, Ali; Gebze Technical University; Omreon; Atlas University
    The emergence of smart cards is a significant achievement in the field of information technology. They are growing in importance as they offer secure data storage and authentication, improve security, simplify processes, reduce costs, and have a variety of applications. In particu- lar, nowadays SIM cards play a vital role in the Telecom industry as an important type of smart card that allows a user to make calls, send messages, store details such as phone number and network authentication information, and provide various mobile data services. Currently, some leading companies take advantage of having their own smart card operating systems and have significant impact on the market on various issues (hardware on which the smart card operating system will run; security restrictions; control, permission and control of any application, etc.). It is important to work on creating a more flexible, adaptable and secure operating system infrastructure in order to overcome these limitations both in the customer perspective and in the ecosystem. The purpose of this research is to introduce the creation of a special Java Card operating system designed for SIM cards used in the Telecom industry. The study presents the software requirements and development steps of the proposed operating system and innovative architectural components necessary for its operation as a SIM card beyond being a Java Card operating system. The proposed new Java Card based SIM operating system is expected to pave the way for the development of eSIM operating system infrastructure as well as 5G tech- nology and offer valuable opportunities.

    The Network Load Balancer in Decentrilized Systems
    (Видавництво Львівської політехніки, 2023-02-28) Klymyshyn, Nazarii; Lviv Polytechnic National University
    This article explores the implementation of network load balancing in decentralized systems using OpenWrt, Quality of Service (QoS), and traffic balancing techniques. The increasing demand for high-quality net- work services and the surge in network traffic requires the adoption of more efficient load-balancing methods to maintain network performance. This paper discusses the use of OpenWrt, an open-source firmware for network routers, to configure and manage network traffic. The article also covers the implementation of QoS and traffic balancing techniques to optimize network performance and reduce network congestion. The study employs iperf3 to evaluate network performance and demonstrates the effectiveness of the proposed network load-balancing approach. The index terms include OpenWrt, QoS, balancing, traffic, and iperf3.

    The main purpose of this work is to analyze and compare several technologies used for training speech models, including traditional approaches as Hidden Markov Models (HMMs) and more recent methods as Deep Neural Networks (DNNs). The technologies have been explained and compared using word error rate metric based on the input of 1000 words by a user with 15 decibel background noise. Word error rate metric has been explained and calculated. Potential replacements for compared technologies have been provided, including: Attention-based, Generative, Sparse and Quantum-inspired models. Pros and cons of those techniques as a potential replacement have been analyzed and listed. Data analyzing tools and methods have been explained and most common datasets used for HMM and DNN technologies have been described. Real life usage examples of both methods have been provided and systems based on them have been analyzed.

    Propagator-Oriented Programming Model Using Java
    (Видавництво Львівської політехніки, 2023-02-28) Bilyk, Vladyslav; Sachenko, Anatoliy; Lviv Polytechnic National University
    The aim of this work is to explore and analyze an unconventional style of programming based on a pro- pagator-oriented model of computation. The paradigm of propagation is characterized by networks of local, independent, stateless machines interconnected with stateful storage cells. This model allows for a highly modular design and multidirectional computation, enabling the creation of complex systems that can respond to changes and update their state accordingly. This work provides an overview of the propagator- oriented programming model, its motivations, and its advantages over other well-known alternative styles, using unsophisticated examples written in the Java programming language. We illustrate how propagator networks can be used to build flexible and efficient systems and present a basic framework for building such networks. The foun- dational components of the propagation model are imple- mented in Java as groundwork for the general-purpose framework. We demonstrate the power of propagator-oriented prog- ramming through an example of a Pythagorean Theorem implementation. The example shows how the model can be used to build complex systems of an arbitrary number of constraints and cells. We highlight the importance of information propagation over limited linear computation and the benefits of the multidirectional computation enabled by propagator networks.
