Simulation of network systems based on loop flows algorithms

This paper presents a simulation scheme for water distribution systems based on loop flows algorithms. Water networks are large scale and non-linear systems. The operational control of such system has posed difficulties in the past to the human operator that had to take the right decisions, such as pumping more water or closing a valve, within a short period of time and quite frequently in the absence of reliable measurement information such as pressure and flow values. Computer simulations of such systems have alleviated these difficulties. They allowed 'what-if' scenarios to be run by the human operator, giving him the possibility to know in advance the operational problems that can arise in the real-life networks due to malfunctions of valves or burst in pipes. However, these computer simulations are generally relying on solving a system of equations and the nodal heads variables have been the most frequently used variables in these computer simulations. More recently, the numerical algorithms based on lo

TCP/IP connection management using a real-time development tool

The Central Integration Unit (CIU) is a major component of a system being developed to provide voice and data communications between mobile radio users and fixed terminal users. The CIU has several different TCP/IP interfaces, both external and internal to the CIU, with varying characteristics. Some use permanent connections whilst others use transaction-based connections; some are clients or servers, others incorporate both client and server operation. This paper looks at the issues behind the design of the connection management aspects of the CIU and then describes the implementation of the connection management software within the CIU

Modelling the Positional and Orientation Sensitivity of Proximity Sensors.

This paper presents an analysis of robust proximity sensor interfaces for Industrial Internet of Things applications. A Model is presented with the aim of maximizing the range and freedom of orientation of passive sensing and communications devices in comparison to traditional source-sensor technologies. A matrix transformation approach is used to model the quality of mutual coupling between triaxial source and sensor coil arrangements for arbitrary relative position and angular rotation. Particular attention is paid to the recombination of triaxial sensor outputs and optimal rotation for maximal coverage given a specified coupling threshold. The model is useful for determining practical source-sensor configurations that achieve optimal coverage when the sensor position and rotation is restricted by the industrial application
