More standardized, networked and intelligentized nature of industry 4.0 has intensified critical infrastructures cyberthreats. According to cyber-physical systems (CPS) layered architecture security requirements in 4.0, a testbed based on cloud computing software defined network (SDN), or CPSTCS is proposed. The uses SDN recreate the cyber elements real-world physical devices for components. helps assess cyberthreats against dimensions infrastructures.

With the rapid development of information and automatic control technology, more industrial system(ICS) like SCADA, is interconnected with Ethernet directly connected to internet, which greatly improve efficiency data sharing introduced in security threats at same time. As important components critical infrastructure, if attacked, will behave abnormal result disasters society countries national economy. one most import protocols applied widely industry field, OPC responsible provide...

The Linear Parameter Varying Dynamical System (LPV-DS) is an effective approach that learns stable, time-invariant motion policies using statistical modeling and semi-definite optimization to encode complex motions for reactive robot control. Despite its strengths, the LPV-DS learning faces challenges in achieving high model accuracy without compromising computational efficiency. To address this, we introduce Directionality-Aware Mixture Model (DAMM), a novel applies Riemannian metric on...

The complex etiopathology of retained placenta (RP) and hazards associated with it has made crucial for researchers clinical veterinarians to study pathogenesis, early-warning diagnosis, treatment. This aimed screen the potential prognostic markers RP in dairy cows using plasma metabolomics coupled laboratory indicators. Blood samples were collected from 260 at 21, 14, 7, 0 days before parturition 21 after parturition. Consequently, 10 healthy similar parity, body condition score, age...

This paper introduces the gray clustering theory as a method to conduct an information security risk assessment for power substation communication systems using with combination of AHP and Delphi method, improves system model based on theory. Analysis albino by constructing weight function determine level quantification membership functions targets. Use examples prove that this can effectively evaluate risks system, provide theoretical guidance both management establishment protection system.

Stuxnet event in 2010 causes the intense attention all over world about information security problems of industrial control systems, how to assure systems has become a hot topic both industry sectors and academic community. In this paper, we focus on testing devices. We first review existing certifications area analyze features these certifications. Then, describe standards area. Furthermore, compare tools used for Following work, can begin further study emerging field.

Based on Dempster-Shafer (D-S) evidence theory of data fusion technology, a new intrusion detection system (IDS) model with C-SVM classifier is proposed. This consisted three SVM classifiers, which sorted out Normal, DoS, U2R, R2L and Probing behaviors from network connections according to basic TCP features, content features traffic features. Those classified results were obtained through Dempter-Shafer's rule combination, consequently recognitions implemented. The experimental result...

Steganalysis is the opposite art to steganography, whose goal detect whether or not seemly innocent objects like image hiding message. With explosive growth of Internet information. Making real time steganalysis online malicious use multimedia documents for covert communication has become more and difficult. Traditional research on mainly focus how improve accuracy Steganalysis, few them pay much attention efficiency Image technology architecture optimizing service providing. Regarding this...

Several common aspects NCR, Emulab, Testbed@TWISC, DETERlab, PlanetLab, SATURN, StarBED GENI are introduced, mainly including: background, techniques, architecture. Finally, we propose trends testbed, on one hand integration cloud computing, software defined (SDN) kits in...

This paper begins with a discussion of the deficiency current algorithms which use number changing points frame-difference as threshold to determine moving object. Based on human morphology, feature body in video surveillance is analyzed. Secondly, "the head and shoulder projection curve"," proportion hair "and "height-width ratio "are extracted three key parameters by mathematical methods. Finally, two are used detect target, replacing existing threshold. DSP-based experimental results show...

Dynamic tracing and trace replay are two main functions in vehicle monitoring system of GIS. Based on the idea line-to-point set, "point-to-point" road matching algorithm "Trace interpolation" designed implemented. The "Point-to-point" is that will be separated into a series discrete set points, then got path matched accordingly. At same time, prediction principle used to solve problems such as miscarriage justice at crossroads; First all, premise applying studied, process introduced. It...

Power production control system is very important in the power system. In paper, a new method of risk assessment for based on rough set theory, fuzzy mathematics and Bayesian network(BN) presented. Though cluster influencing factors by using compatibles set, making minimum feature class as BN node, which can effectively reduce complexity structure, At same time, carry probabilistic reasoning BN, achieve rapid risk, then through Anti-fuzzification, obtain exact value risks. Finally, examples...

Designated verifier signature, was proposed by Jakobsson, Sako and Impagliazzo, is an important cryptographic primitive which can be used to convince a single third party, i.e. the designated verifier, only who convinced fact that always construct signature intended for himself indistinguishable from original signature. Since notion of introduced, lot schemes were in literature. In this paper, we propose first scheme circulant matrices. We show secure under computational Diffie-Hellman...

This study was conducted to determine the antimicrobial resistance and virulence traits of 32 Enterococcus faecium isolates from clinical bovine mastitis cases in Ningxia Province, China.
