Software-defined networking (SDN) addresses pressing networking problems such as network virtualization and data center complexity. By separating the control plane from the data plane, SDN introduces a new abstraction layer. This new abstraction layer is typically implemented by means of a so-called SDN controller. SDN applications can interact with the controller to ensure network functionality....
In this paper, a novel kernel independent component analysis method which is named improved DKICA is proposed for dynamic industry processes' fault detection and fault diagnosis. The primary idea of this method is how to obtain an augmented measurement matrix in the data kernel space, the independent component analysis is used, so the dynamic and nonlinear features can be extracted in non-linear non-Gaussian...
Pneumatic control valves are the most frequently used actuators in industrial processes. Its property definitely affects the performance of processes and therefore process monitoring of the pneumatic control valve is of great importance. Canonical Variate Analysis (CVA) is a multivariate data-driven method which considers time correlations and has been demonstrated to be superior to some methods in...
The fruit export market in Chile lacks of an online system or procedure for quality control of export fruit, which considers the minimum mandatory parameters that different types of fruit must meet in order to be exportable to different destinations. To solve this problem, we designed an information system that allows the online control quality of export fruits during the different stages of the productive...
On the information security of ACS TP negatively influenced by increasing their integration with enterprise systems management, as well as the wide spread of remote access technologies. Additional information security risks arise on the background of the smooth transition analogue of technology on hardware platform based x86, and active implementation of IP technology in the ACS environment. The combination...
A new structural diagram of the control system for the production process (PP) of proportional electromagnets is proposed. The device includes a device for monitoring and analyzing the electrical parameters of proportional electromagnets in order to obtain information on the PP progress. It is proposed to carry out the measurement of the dynamic magnetization characteristic (DMC) for quality control...
In this paper, after a brief introduction on the proposed plug-and-play (PnP) process monitoring and control system, two online configuration approaches are proposed for the observer-based residual generator. Firstly, an adaptive residual generator is developed based on the adaptive observer scheme. Aiming at higher feasibility and reliability of industrial application, an iterative learning approach...
Landslide monitoring is crucial for early detection of landslide hazard and reduce the risk of a landslide. In this work, a Ground-Based Synthetic Aperture Radar (GB-SAR) system intended for landslide monitoring has been developed. The system is used to cognize a point target located at a certain distance. This GB-SAR system consists of portable VNA module, SAR processor, stepper controller, linear...
Despite the great benefits of cloud computing on businesses, some organizations have had to withdraw from its service due to incomplete compliance to conditions from standards, bodies, or Service Level Agreements which have led to their being penalized. A structured and efficient model is helpful to aid small and medium scale enterprises (SMSEs) utilize cloud services safely and ascertain their fitting...
In this paper, a novel classifier for classification problems, based on increment support vector data description, is proposed. The proposed method is the expand version of increment support vector data description by bring in two classes of sample. Because of the addition of two kinds of sample. This method can reflect the target sample distribution state more complete in super ball space. The results...
This paper examines the model of alarming information processing in the measuring system, which integrates the properties of remote signaling system and telemetry system. The overshoot of the controlled parameter beyond the threshold level is the measurement result in the system, i.e., the alarm signal. The exponential character of the alarm level distribution at the input of an analog-to-digital...
Process monitoring and controlling system is essentially a data monitoring event transmission system, they are usually developed based on the procedure languange C with high cost and in low maintainability. functional reactive programming is a time-saving, bug-preventing programming paradigm worthy of control system to implement. In this paper the implementing the new kind of functional reactive programming...
PLS is widely used in the quality control process system, but it has poor capability in some strong local nonlinear system for fault diagnosis. To enhance the monitoring ability of such type fault, a novel statistical model based on global plus local projection to latent structures (GPLPLS) is proposed. Firstly, the characteristics and nature of quality-related global and local partial least squares...
A novel fault detection method based on margin statistics of generalized non-negative matrix factorization (GNMF) is proposed. The construction of traditional process monitoring method based on multivariate statistical that neglects the correlation relation and feature distribution of latent variables at different sampling times, and the method also need to assume that latent variables satisfy a particular...
Data-driven fault detection technique has been widely applied for process monitoring, which can effectively detect faults happened in industrial processes. It is extremely significant for guaranteeing the normal operation of processes. Independent Component Analysis (ICA), a type of Data-driven fault detection technique, has been successfully applied to Blind Source Separation and process fault detection...
Companies commonly establish and pursue business goals for different purposes. Many purposes, such as to understand, improve, compare, monitor and control, among others, may be driven by measurement, evaluation and analysis activities. Different strategies can be used to help achieving goal purposes. A strategy defines a set of activities and methods related to nonfunctional requirements, measurement,...
Programmable Logic Controllers are used for smart homes, in production processes or to control critical infrastructures. Modern industrial devices in the control level are often communicating over proprietary protocols on top of TCP/IP with each other and SCADA systems. The networks in which the controllers operate are usually considered as trustworthy and thereby they are not properly secured. Due...
This paper addresses the shared resource contention problem associated with the auto-parallelization of running queries in distributed stream processing engines. In such platforms, analyzing a large amount of data often requires to execute user-defined queries over continues raw-inputs in a parallel fashion at each single host. However, previous studies showed that the collocated applications can...
In this paper, an approach to the organization of spatial-temporal processing of geoelectrical data in the system of automated geodynamic control is considered. It allows combining methodical, algorithmic, program and information support of the processes of collecting and processing of geodynamic information at subjects to control. Use of the relations obtained simplifies the geodynamic estimation...
