The widespread use of the Internet of Things (IoT) technology has both good and bad things about it. There must be a full and reliable security system in place for the Internet of Things so that things can work together in a safe way and intrusions cannot happen. There are now many more ways to keep the Internet of Things safe, thanks to a detecting system. As machine learning and deep learning technologies have become better, a lot of good intrusion detection systems have been made. This kind of study is covered. These two types of security are compared in this study. The current machine-based intrusion detection system is broken down into more detailed categories based on detection technology, data source, architecture, and operating method. These categories are as follows: It is talked about how IoT security will grow in the future and how to understand its intrusion detection system too. In this paper, a cloud-based blockchain security model has been presented for secure data transmission over IoT.

This paper presents a benchmark problem for fault diagnosis of an internal combustion engine that has been formulated and solved. The objective is to design a diagnosis system using and incomplete model information training data that only contains a limited set of fault realizations. Six different solutions to the benchmark, that were presented at the IFAC Safeprocess symposium 2024, are described and evaluated. The contribution of this paper is the benchmark and the presentation of six different solutions in one paper. The paper is intended to provide a starting point for engineers and researchers who work with fault diagnosis and monitoring of technical systems.

In this work, the radiation responses of Zr/Nb nanostructured metallic multilayers are studied. The nanostructures with diﬀerent layer thicknesses were deposited on Si (1 0 0) substrate by using magnetron sputtering and are subjected to heavy-ion irradiation with different fluences. Nanoindentation, XRD, SIMS, and Variable Energy Positron Annihilation Spectroscopy (VEPAS) techniques were used to study the changes in the hardness of the structures as well as the type and distribution of defects, and strain within the material as a function of damage. Our results suggest that the irradiation hardening is independent of the type of implanted ions, and its magnitude decreases with decreasing individual layer thickness indicating that the number of interfaces has a direct effect on the radiation tolerance enhancement. For thin layers, a transition from hardening to softening occurs at high fluence, and a saturation point is reached in thick layers. The as-deposited thin multilayers presented significantly higher atomic-scale disorder which increases with ion irradiation compared to the thick multilayers. VEPAS reveals the vacancy defects before and after irradiation that contribute to the presented strain. Thin nanostructured Zr/Nb multilayered structures possess excellent radiation resistance due to the high density of interfaces that act as sinks for radiation-induced defects. © 2022, The Authors.

Resonant beam communications (RBCom) is capable of providing wide bandwidth when using light as the carrier. Besides, the RBCom system possesses the characteristics of mobility, high signal-to-noise ratio (SNR), and multiplexing. Nevertheless, the channel of the RBCom system is distinct from other light communication technologies due to the echo interference issue. In this paper, we reveal the mechanism of the echo interference and propose the method to eliminate the interference. Moreover, we present an exemplary design based on frequency shifting and optical filtering, along with its mathematic model and performance analysis. The numerical evaluation shows that the channel capacity is greater than 15 bit/s/Hz. Copyright © 2021, The Authors. All rights reserved.

Motor Bearing Fault Diagnosis Based on Frequency Conversion Estimation and Order Analysis

Procedia Manufacturing 2020年 49卷 160-165页

Order analysis (OA) has been proven to be an effective tool for motor bearing fault diagnosis under variable-speed conditions, but it is a challenge to perform OA when a tachometer is unavailable to obtain the rotating speed. In this study, a new angular resampling method based on instantaneous frequency estimation of the transient current signal is proposed for bearing fault diagnosis with speed fluctuation. First, the fundamental rotating frequency curve is extracted from the acquired phase current signal of a brushless direct current motor (BLDCM). The mechanical rotating angle curve is then calculated by integrating the fundamental frequency curve. The synchronous sampled vibration signal of the fault bearing is resampled in the angular domain according to the obtained rotating phase information. The effectiveness and efficiency of the proposed method are verified through a BLDCM experimental setup.

Humans continual learning (CL) ability is closely related to Stability Versus Plasticity Dilemma that describes how humans achieve ongoing learning capacity and preservation for learned information. The notion of CL has always been present in artificial intelligence (AI) since its births. This paper proposes a comprehensive review of CL. Different from previous reviews that mainly focus on the catastrophic forgetting phenomenon in CL, this paper surveys CL from a more macroscopic perspective based on the Stability Versus Plasticity mechanism. Analogous to biological counterpart, "smart" AI agents are supposed to i) remember previously learned information (information retrospection);ii) infer on new information continuously (information prospection:);iii) transfer useful information (information transfer), to achieve high-level CL. According to the taxonomy, evaluation metrics, algorithms, applications as well as some open issues are then introduced. Our main contributions concern i) rechecking CL from the level of artificial general intelligence;ii) providing a detailed and extensive overview on CL topics;iii) presenting some novel ideas on the potential development of CL. © 2021, CC BY.

IEEE International Conference on Intelligent Data Acquisition and Advanced Computing Systems

The article presents two approaches to the method of implementation of transformations of fuzzy queries into queries in the SQL standard. This implementation can be carried out: (1) in a database (in the form of functions, procedures, triggers or other acceptable form), using the existing query processing system in the database, and thus it can expand the functionality of that database;(2) in an application (which communicates with the database), and thus a considerable portion of calculations will be transferred from the database to that application. An analysis of those approaches was conducted and it was demonstrated that the presented methods should enjoy extensive practical application.

Co-operation of the control logic of the T-shape road intersection and the near railway level crossing

引用

Transportation Research Procedia 2019年 40卷 1465-1472页

作者： Roman Michalík Aleš Janota Dušan Nemec Marián Hruboš Department of Control and Information Systems Faculty of Electrical Engineering and Information Technology University of Žilina Univerzitná 8215/1 010 26 Žilina Slovakia

The paper deals with the problem of traffic control in the situation when controlled road intersection of the T-shape is situated close to the railway level crossing. That configuration very often brings some additional risks resulting from the phenomenon known as “blocking back”, i.e. blocking movement of road vehicles found at the level crossing when a train is approaching and passing. There are various approaches how to eliminate that risk, one of them consisting in establishing co-operation between both installations and proper modification of signal control phasing of the near controlled road intersection. The authors briefly analyze and discuss the problem, its potential solutions and present applied approach in the form of the animated UML-based model.
