The development of smart grid improves the observability and controllability of power system. Meanwhile, the reliability of information support system has an increasingly important impact on the safe and stable operation of power system. In the source-grid-load (SGL) system, the design purpose of fast and precise load control for fault mitigation raises higher requirements on controllability. Malicious attacks against the SGL system may lead to serious consequences. To evaluate the security and reliability of SGL system, this paper focuses on malicious attacks against SGL system, and models the attacks with Petri net. Probability of successful attacks that damage the system function is also calculated. On this basis the risk of network attack faced by SGL system is evaluated. Finally, the validity of the proposed modeling method is verified by case study. With the deep integration of industrial control system (ICS) and Internet technology, the security problem of industrial control system is becoming more and more significant. The continuous development and use of power system control equipment and technology make the power system a typical example of industrial control system.

This paper proposes a flexible diagnostic system, named mSDN (multiple Stochastic Diagnostic Net- work). The mSDN efficiently learns quantitative rules, and adapts to patient's individuality. Furthermore, acquired rules by mSDN are comprehensible, that ensures safety. The mSDN applied to a real-time diagnostic system will improve 'quality of life'.

The presence of Distributed Generation (DG) system with the impact to the power swing during the instability was revealed. Some of the scenario which affect to the Zone Protection of Distance Relay has been observed. The result shows that the apparent impedance was passes through both the Zone 1 and Zone 2 of protection of distance relay during installing the DG system to the network. In this study, the distance relay is chosen to be a protective system into the system network in order to protect the transmission lines. The distance relay will have the instantaneous directional Zone 1 protection and one or more time delayed zones. The tripping signal produced by Zone 1 is instantaneous that is should not reach as far as the busbar at the end of the first line so it is to cover only 80-85% of the protected line of transmission lines. The remaining 15-20% provides a factor of safety in order to mitigate against errors introduced by the current and voltage transformer, and line impedance calculations. The 15-20% at the end of the line is protected by Zone 2. All of the circumstances during protective of transmission line with and without DG system have been captured and discussed in the end of this paper.

GPS is a satellite-based positioning and time transfering GPS positioning function has a wide range of applications in the modern measurement and a more modern building. GPS technology is also widely used in modernization building, and now GPS has also been shown to be an important civilian communities of interest, and increasingly wide range of applicated. GPS management system solve the relevant problems of grain plots to forestry engineering effectively. Through the combination of information communication tool and the science and technology of management, a big problem China in environmental protection has been solved. This paper introduces the application of GPS management system in the grain plots to forestry engineering in detail, analyses the deficiency of the existing manual measurement method and expounds the advantages of the GPS management system.

Development of high performance servo-drive systems for mobile weapon platforms demand complex multi-disciplinary engineering skills of tall order. The uncertainties in user. acceptance, with longer development and trial evaluation lead time with no guarantee on the bulk production orders discourages competent large industries in taking up the development challenges of complex systems. This necessitates dependence oil many smaller industries specialized in the various engineering skills needed for the complete system development. This paper describes development strategies that were adopted from the conceptual phase through the other phases of the project viz., design, development.. manufacture, testing of assemblies, integration on the vehicle and trial evaluation that had led to the success of the development project.

Traffic congestions recognized as a significant problem in modern urban cities. Jordan considered as one of the top countries worldwide in terms of frequency of traffic accidents where the increase in the number of vehicles had led to the rise in the number of traffic incidents, involving the increase in fatalities and injuries, but the fixed timers still control the current traffic signals system in Jordan. In this paper, an Intelligent Road Traffic Management system based on Human Community Genetic Algorithm (IRTMS) proposed. The IRTMS compared with the current traffic system in the Hashmet Kingdom of Jordan, which concludes that it has the minimum total time and waiting time compared with the current traffic lights system.

The paper deals with the analysis of the problematic issues of the creation of the system for the provision of the high quality of higher education in Ukraine at the state level. The system of engineering program accreditation in the educational establishments of the USA is shown. The fundamental differences between the engineering and engineeringtechnology training programs are analyzed. The reasonability of such separation and the necessity for the determination and use of different criteria during the accreditation of these programs are stated. Attention is drawn to the necessity for the development of professional standards at the state level and the subsequent creation of higher education standards for the formation of the policy in the field of training a specialist who will be competitive at the labor market.

The industrial panorama is evolving. Using IoT sensors and actuators it is possible to increase product's value, by controlling its production chain. Internet technologies such as FIWARE can provide the services that modern industry needs to process and evaluate sensor data to apply higher production standards, which increase product value. Although FIWARE enablers provide the tools to fulfil modern industry needs, there is an interoperability gap a gap between applications and enablers, as different enablers have different protocols and needs. This article describes an agriculture system developed using vf-OS (virtual factory Operating system), a platform that aims to become the bridge between applications and enablers, as it provides the means to interact with them. The developed system is composed of different applications, that use enablers (integrated using the vf-OS system), current context management and fruit quality theories, to control product quality during the whole fruit production chain.

For providing an automatic warning system of running-out of injection fluid, RFID technology is applied in this work to propose an infrastructure with low cost to help nurses and patient's company. Specially, a RFID tag is designed and attached on a bag of intravenous drip to demonstrate the benefits in the present system. The main idea of this system is that, tag is disabled when the bag is not empty because of the EM loading due to the liquid contained. The bag can be any kind in the current market and be without any electronic attachment or modification. LAN (Local Area Network) is also applied as a part of this infrastructure for data transmission.
