Data-Driven Detection of Wheel Imbalance Using Accelerometer Signals and Fuzzy Logic

This paper presents an experimental study of imbalance detection in a rotating bicycle wheel using vibration measurements from a tri-axial accelerometer. A laboratory test bench, in which a bicycle wheel equipped with an in-wheel motor has been mounted on a stand and instrumented with an accelerometer for real-time vibration monitoring, has been developed. Experiments have been conducted under balanced conditions and under controlled imbalance introduced by adding external mass to the wheel rim. Acceleration signals have been collected and analyzed in time and frequency domains.

Performance Evaluation of ESP-NOW for Low-Latency Indoor IoT Systems

This paper presents an experimental study of communication latency in ESP-NOW wireless networks under different indoor conditions. A testbed consisting of three ESP32 devices (one master and two slave nodes) has been developed to evaluate one-way transmission delays without the use of a Wi-Fi access point. The slave nodes generate periodic sensor traffic and transmit data simultaneously, creating controlled network load conditions. A software-based time synchronization mechanism based on a message-exchange protocol has been implemented to estimate one-way latency.

Research on data transmission technologies and information security in IoT networks

Important functions of the Internet of Things (IoT) concept include facilitating everyday life, increasing work efficiency and quality, energy saving, and more. Increasingly, data from "things" are transmitted to public communication networks and cloud services. Any objects in the physical world that can be assigned IP addresses and are capable of transmitting data can act as "things" in such a network. Various technologies and protocols are used for data transmission, with more than twenty currently available.

An Adaptive Framework for Real-Time Intrusion Detection in WSNs and IoMT: Comparative Study using CICDDoS-2019, WSN-DS and CICIoMT2024 Datasets

Despite the high amount of research on networks and systems security, that comes out every day, the field of intrusion detection still attracts the interest of many researchers as one of the most important axes that contribute to understand the attacks behavior for providing an efficient and accurate solution with low cost.  Wireless sensor network and Internet of Things are one of the special networks that have several constraints, limited computational resources, and the most vulnerable for attacks, especially, DoS and DDoS attacks, which considered as the most danger

Remote Monitoring System for Microclimate Parameters of Smart Home and Industrial Premises Based on ESP8266 Microcontroller

The paper analyzes developments in the field of environmental parameter monitoring using microcontrollers and Internet of Things technologies, with results that justify the use of ESP8266 microcontroller. A monitoring system for microclimate parameters (temperature, humidity and atmospheric air pressure) in smart homes and industrial  premises based on ESP8266 microcontroller has been developed, which demonstrated its effectiveness through a combination of hardware and software tools.

Revolutionizing Modern Healthcare Delivery through Sustainable IoT-based Continuous Real-Time Patient Monitoring

The advancement of Internet of Things (IoT) technology has revolutionized healthcare by enabling continuous, real-time monitoring of patients' vital signs.  This project introduces the "MedSen IoT", a cutting-edge medical device designed to measure and monitor critical health parameters such as blood oxygen saturation blood oxygen saturation (SpO2), heart rate (BPM), body temperature, room temperature, and room humidity.  MedSen IoT combines sophisticated sensor technology with IoT connectivity to offer a comprehensive, user-friendly health monitoring solution.  The dev

A Permission-Blockchain Framework for Service-Level Agreements in the Cold Chain

Cold-chain logistics needs decisions that are fast in operation and defensible at audit. This article presents a compact, evidence-centric workflow for service-level agreements (SLAs). SLA clauses are encoded as smart- contract rules on a permissioned blockchain with Byzantine fault-tolerant consensus (Hyperledger Fabric).

The Impact of Digitalization on Enterprise Scaling and Transformation

The paper reveals the essence of business scaling tools, which are considered as a set of interrelated technological, organizational and digital solutions. These tools are aimed at ensuring flexibility, efficiency and effectiveness in the process of expanding the activities of enterprises, especially when entering international markets. This includes, in particular, the use of digital platforms, ERP systems, cloud technologies, intelligent management systems, as well as demand forecasting and supply chain optimization models.
