Care of critically ill patient requires prompt & accurate decisions so that life-protecting and lifesaving therapy can be properly applied. Because of these requirements, ICUs have become widely established in hospitals. Difficulty found in most hospitals is that expert has to frequently visit the patient and checks condition of the patient by measuring different parameters. This paper presents...
This paper is presented to introduce a system constituting of a PLC (Programmable Logic Controller) that is connected to the level switches which is monitoring the level of the tank. This system saves the tank from over flowing which increases the safety and efficiency. The levels are considered as an input to the PLC and the pump is controlled by the output of PLC which pumps out the solvent or any...
Software Defined Network (SDN) is a proposal to networking world for global administration and management of network services. It also provides an abstraction of networking elements. Most of the security innovations in SDN are bound to an OpenFlow security framework which creates and implement security policies while detecting malicious traffic, that too in a flexible way. Existing methodologies convert...
This paper presents the design and implementation of the ALICE O2 Control System prototype. The design of our system is based on the ALICE O2 requirements. The system allows the crew operating the experiment to send simple commands in order to control the ongoing processes running in the computing farm. The sent command is capable of reacting to changing conditions and operational the requirements...
Operator situational awareness in Nuclear Power Plant (NPP) control rooms is quintessential in ensuring plant safe operation. Towards improving situational awareness, a novel framework of the EYE - Expert Supervisory System capable of visually monitoring human machine interfaces (HMI) in cyber physical system (CPS) is proposed with target application in NPP control room environment. EYE applied on...
The Copy Exactly! methods have evolved throughout a twenty-five year journey from initial process tool configuration and bill of materials matching to include factory infrastructure, human factors, process controls, and process indicators matching. These methods have delivered high reliability across billions of microprocessors largely without dedicated reliability monitoring systems. How is this...
In this paper we describe a streamlined process for transforming high-level tasks into executable implementations created with the Robot Operating System (ROS). We leverage both the vast availability and functionalities of ROS packages and recent advances in automatically synthesizing provably-correct controllers from high-level specifications. Specifically, we propose a framework for seamless integration...
The paper puts forward new ideas for the establishment of distributed price monitoring system on based on the Multi-Agent theory, in order to make the price monitoring process intelligent, the fault diagnosis of real-time price intelligent and conflict resolution intelligent. Price monitoring intelligent system based on Multi-Agent, which realize the intelligent operation, control and supervision...
Fault prognostic in various levels of production of semiconductor chips is considered to be a great challenge. To reduce yield loss during the manufacturing process, tool abnormalities should be detected as early as possible during process monitoring. In this paper, we propose a novel fault prognostic method based on Bayesian networks. The network is designed such that it can process both discrete...
This paper describes the proposed system, which is able to control, monitor and record the usage of home electrical devices. The system is designed to overcome the high cost and inflexible of electrical device's installation due to rearrange rooms, and the demand of user to be able to monitor the electrical usage. Here, the system was developed using micro-controllers equipped with WiFi modules, which...
Process mining research discipline offers a spectrum of techniques for analysing event logs. Event logs represent the history of process execution. This information can be used for monitoring, analysing and improving the operational processes. The currently available methods in process mining emphasise on constructing the static process model. These models depict various dimensions of the process...
World-class organizations use sophisticated control processes to ensure their success. These companies may use a combination of feedback and feedforward technologies to be either reactive or proactive to disturbances destined to upset their carefully designed systems.
Different approaches of communication are available between the Mitsubishi FX-PLC and LabVIEW like OPC, Serial, etc. The communication between the PLC and personal computer (PC) is done using the Ethernet 1E. A MELSEC Communication (MC) protocol of Mitsubishi FX-series Programmable Logic Controller (PLC) is introduced and studied. LabVIEW is used as programming software. This communication has been...
Attacks targeting software on embedded systems are becoming increasingly prevalent. Remote attestation is a mechanism that allows establishing trust in embedded devices. However, existing attestation schemes are either static and cannot detect control-flow attacks, or require instrumentation of software incurring high performance overheads. To overcome these limitations, we present LO-FAT, the first...
This paper deals with a detection approach that tries to solve major problems of traffic flow by combining a higher order modeling tool and the principal components analysis. This modeling system is applied to the data preprocessing level. The PCA is introduced for fault detection by comparing the method of SPE and Hotteling T2. For fault isolation, calculating contributions enables identify faulty...
The article examines the development of digital manufacturing production, in particular the system for monitoring the work of CNC equipment, CNC equipment circuits and other automated manufacturing equipment, as well as systems of monitoring and resource suppy for the implementation of production tasks and production plan of the digital manufacturing production. The developed system has the following...
Cyber-Physical Systems (CPS), which integrate controls, computing and physical processes are critical infrastructures of any country. They are becoming more vulnerable to cyber attacks due to an increase in computing and network facilities. The increase of monitoring network protocols increases the chances of being attacked. Once an attacker is able to cross the network intrusion detection mechanisms,...
The identification of change points is often considered as a model selection problem and the most commonly used methods are the Akaike information criterion (AIC), Bayesian information criterion (BIC) and their modified versions. These methods rely on the parametric distribution of the characteristic of interest, and any deviation from the specified parametric model may lead to incorrect conclusions...
Loss functions have been well studied for decades. Some researchers use loss function to design control charts economically, but few have used loss function to construct control charts directly. We propose a new class of control charts based on the concept of quality loss function. Our charts can be used for both univariate and multivariate processes, and they are more sensitive than Shewhart control...
A new approach in FDC takes advantage of the full sensor trace for fault detection which allows engineers to uncover issues more thoroughly and accurately. The solution utilizes a reference model that intelligently adapts to process changes and requires minimal effort to set up. This greatly reduces the time required to deploy and virtually eliminates maintenance for an FDC system. The elimination...
