This paper presents a new approach for tuning three-term control loops encountered in power station processes. The proposed approach is based on the Pseudo-Derivative Feedback (PDF) control configuration. Simple methods are presented for tuning the PDF controller for dead-time processes. The methods are based on appropriate manipulations of the exponential dead-time term in the denominator of t...

The main aim of smart grid was to maintain a secured and reliable electricity infrastructure to transfer data from smart meters to destinations. Now a day’s data security plays a major role in communication i.e; data must be secured from the destructive forces and unauthorised users. The basic idea of this paper is to transfer data which is generated from smart meters or any other source secure...

abstract minimizing service cost and adverse effects on environment and society are important in waste management. due to this, landfill and transfer station location become important. this article as a practical research uses analytical hierarchy process in multi criteria decision making considering environmental and social criteria in levels of benefit, opportunity, cost and risk (bocr) for p...

The NBS Boulder Laboratory is in the process of assembling a very high accuracy time transfer system. The system includes a 6.1 meter Ku-band satellite earth station, two transportable earth stations each with a 1.8 meter dish, and commercial modems designed for two-way timing. Elements of the facilities are described in this paper. High-accuracy timing with this equipment using the two-way tim...

The "seismic equalization" problem is that of correcting the response at one station to match that at another station which may have different instrument characteristics and different (and unknown) local reverberation characteristics. In this note, the problem of seismic equalization is formulated mathematically, and that portion involving measurement or estimation of a transfer-function ratio ...

This study develops an NN typhoon wave model to accurately and efficiently calculate wave heights at a point of interest. Multi-trend simulating transfer functions were first introduced to exemplify the relationship between wave heights and each conceivable input factor by regressive fitting. The proposed NN–MT model can accurately forecast wave peak with an error of less 1.2 m and with time de...

Network lifetime is one of the critical performance parameters in Visual Sensor Networks. In order to avoid transmission of redundant information to the base station, it becomes necessary to select among the nodes in the neighboring region having the same area of coverage for data transfer. This work presents an efficient approach aimed at reducing the extra amount of information to the control...

A client-server based data communication scheme was developed in order to establish a permanent and dynamic real-time GPS network for relative time and frequency transfer. The Kalman-filter-based real-time processor uses station pairwise common-view phase observations for estimating the receiver clock and tropospheric parameters. Orbit determination is based on real-time broadcast ephemerides a...
