Video shot boundary detection is a fundamental step towards video information processing in e-learning scenarios. In the field of shot boundary detection, there still exists difficulty in choosing suitable thresholds for different videos, and empirical thresholds usually lead to low precision. Thus, we propose an original method to generate video-based threshold which is calculated by video itself...
An intrusion detection system (IDS) monitors the network traffic looking for suspicious or malicious activities or policy violations, which could represent an attack or unauthorized access. Traditional systems were designed to detect known attacks but cannot identify unknown threats. They most commonly detect known threats based on predefined rules or behavioral analysis through baselining the network...
This article describes the general theory of determining the time response characteristics of different component parts of modern automated control systems (ACS) and the method of calculating constraints on the time response characteristics of information security systems (ISS) used in ACS as real-time systems. For an arbitrary manufacturing process (both under development and existing) ACS, this...
In recent years, the statistical inference and algorithm for the complex diffusion process of incomplete data have become a hot topic that scholars of probability and statisticians are concerned with and calls for further study. Based upon the all-directional, multi-angle random dynamic information flow research, this article expands the information flow research in the ordinary information space...
A spatial load forecasting method based on unstructured information processing and multi — attribute depth learning is proposed. In order to solve the problem that the unstructured attributes have great influence on the load density but can't be directly put into calculation, the natural language processing (NLP) technique is used to structure those attributes. In view of the on characterization of...
The paper deals with the processing of information on the state of a computer system using probabilistic automata. An intelligent system model for the detection and classification of malicious software is proposed which compares a set of features that are characteristic for different classes of viruses with multiple states of the machine. The analysis process is reduced to the modeling of the automaton...
A novel algorithm is proposed for the direction-of-arrival (DOA) estimation of coherently distributed (CD) sources. Based on the symmetric property of the uniform linear array (ULA) geometry, the DOA can be estimated by a one-dimensional peak search without estimating the distribution parameters, where N independent CD sources can be distinguished with a ULA of 2N + 1 elements. Compared with the existing...
Consider in an asymmetric scenario that Alice and Bob wish to communicate unequal amount of classical information, we propose an asymmetric quantum dialogue (QD) protocol based on the entanglement swapping between two-qubit bell state and four-qubit cluster state. In this scheme, assume that there are two legitimate participants Alice and Bob. In a dialogue, the information that is delivered by Alice...
The algorithm of formation to structure of self-regulating technical system, optimum on Pareto, which quality is defined by the plan of measurements from agents, on the basis of kvalikativny functions is considered.
Spurred by advances in scalable photonic system integration, ideas in photonic information processing have recently experienced a resurgence. We review the latest results in reconfigurable analog photonic networks, neuromorphic photonics, and multivariate RF photonics. These architectures could enable next-generation microwave signal processing and scientific computing.
Processing of information from the sensors and the resources available to the commander are very important for his decision-making process. Quality of information for decision-making process has a great importance. This article focuses on the description of the modeling of signal processing from sensors in a probabilistic model of recognition Custom / Foreign Identification Friendly or Foe and access...
In this paper, we describe and describe the quality indicators for the development of an adaptive user interface for 3D mnemonic schemes in the DSS. These indicators are of particular relevance for man-machine systems in critical applications: rocket and space technology, nuclear and thermal power engineering, transport systems and many others.
This paper proposes a event-triggered formation control method for a leader-follower multi-agent system. The purpose of the multi-agent system is to add more function to the system by cooperative control of multi-robots. Research of multi-agent system is useful for society. Generally, in conventional research, each agent always need to communicate with neighbor agents. So, communication failure like...
The information transmission problem in a class of wireless multi-user single-antenna half-duplex relay interference networks is studied. In these networks there are multiple clusters of sources. All the terminals in each source cluster desire to transmit independent messages to a single destination, through multiple layers of intermediate half-duplex relays. We adopt a cluster successive relaying...
Event-triggered mechanism is applied to multiagent systems in order to reduce the amount of information transmission. In this paper, a novel centralized/distributed hybrid event-triggered mechanism(HETM) is proposed. It is shown that the proposed event-triggered mechanism not only guarantees the consensus of multi-agent systems but also effectively avoids the Zeno behavior. Then, we further consider...
In this paper, the effects of autapse (a kind of synapse formed between the axon or soma of a neuron and its own dendrites) on the weak signal detection capacity of a Hodgkin-Huxley (H-H) neuron are investigated. In the study, we consider that the H-H neuron has an inhibitory autapse modeled as a chemical synapse. The subthreshold sine wave is injected to the H-H neuron as a weak signal. Obtained...
An ultrasonic signal is rarely used for information transmission in solids because it attenuates, scatters, disperses and reverberates in the channel. In some environments, the ultrasonic signal is the only option for communication since radio frequency (RF) electromagnetic waves cannot propagate in the medium. This paper presents the feasibility of using an ultrasonic signal in the frequency range...
A monolithic piezoelectric MEMS-CMOS resonant transformer that can be used in ultra-low-power high-efficiency RF sensing applications is presented for the first time. The MEMS-CMOS resonant transformer is based on a 59 MHz 2-port Aluminum Nitride (AlN) Contour Mode Resonator (CMR) bonded to a 0.18 μm NMOS-based rectifier for voltage boosting and RF-to-DC conversion. The integrated device is fabricated...
The possibility of describing the encoding and decoding procedures Bose-Chaudhuri-Hocquenghem codes using the summation operations modulo 2 is researched. This allows you to simplify these procedures and improve efficiency by correcting the error of the triplicate. There identified coding equations and triangular match tables: the syndrome — the distortion of the position.
