Remote Operated Vehicles(ROV) play an important role in marine economic development, environmental protection and disaster management. This paper introduces the design procedure for the rudder wing of ROV used in marine shallow water areas. First of all, the wing selection of the rudder wing is chosen based on the maneuverability requirements of the ROV Secondly, the 3D model of the rudder wing is...
This paper joins the developing trend of modeling distributed generators based on dq0 quantities, and proposes an open-source software for modeling and analysis of large-scale power networks based on dq0 signals. The dynamic models describing the network are provided as state-space objects that are sparse and of minimal order. The software supports integration of various models of synchronous machines,...
Computerized systems employed for the analysis of cardiotocographic signals have become almost indispensable tools in fetal monitoring, for which evaluation of fetal heart rate signals plays a key role. Consequently to the diffusion of these systems, new software and complex signal processing methodologies are spreading and are gaining more and more interest. For testing the performances of new software...
This article describes the development of a Distributed Manufacturing Systems (DMS) simulation platform. Current technological environments leave no space to faulty and un-optimized manufacturing processes. Being able to prevent these processes is crucial to keep manufacturing systems up-to-date and running smoothly. To ensure it, one can use a variety of methods, such as simulation. The simulation...

The study will be approached by building a simulation model using Arena in order to optimize employees scheduling within reception and housekeeping department during...
As a high-precision multi-axis motion controller designed by Delta Tau, PMAC has been widely used in industrial fields. Mirror image is a function through which can machine the same trace in other place of the workpiece, not only saving the tool setting time but also simplifying the edit of program. By this way, product could have good accuracy and interchangeability. However, researches aimed at...
In this paper, a new cyber-attack is proposed for distributed systems, while detection of such an attack is recommended based on H-infinity filtering. In particular, we study the effect of a specific attack on the communication links between local control centers. Today's cyber-physical systems are complex and large scale, so that they are distributed over a large area. Using distributed control and...
The focus of this paper is emulation of ferrite tile characteristic in WlPL-D Pro 3D EM solver. Usually the characteristic itself is unknown, while the performance characteristic is provided in standard datasheets. By using a relatively simple expressions for EM properties of material, we can proceed to optimize their performance until they reach the specification given in datasheets. A coaxial tube...
This work proposes a residential load management system using multiagent technology with the objective of cost and comfort management. Smart appliances in a residential unit are modelled as agents which are controlled using optimization algorithm. These agents cooperate and communicate with each other using agent communication language (ACL) to reduce electricity cost and high peaks without affecting...

One of the grand challenges for adequately testing scientific software is due to the oracle problem. Metamorphic testing is the promise technique for addressing the problem through checking the satisfaction of a metamorphic relation that defines the correlation on the relation of paired test inputs and the one of their corresponding outputs. Therefore, checking the correctness of an individual test...
