An incremental Optimum-Path Forest classifier and its application to non-technical losses identification

Abstract The flow patterns of a striation through a Cavity Transfer Mixer was demonstrated. These were seen to take an optimum path and action to achieve exponential efficiency of mixing. The striation was seen to turn through 90° before being cut in successive segments, deposited in the next cavity row, and drawn out perpendicular to the original direction of shear. The effectiveness of the CTM is a result of the regular turning and cutting action which had been predicted and which has been demonstrated. Factory trials have shown that polymers and masterbatched materials can be blended efficiently in a CTM unit and that off-specification materials can be processed without further reduction in viscosity. Thermoplastic rubbers can be processed on rubber extruders with plain pumping screws fitted with CTM units to blend color or ingredient masterbatch without prior mixing. We would conclude that all the above advantages are secondary to the main advantage of “temperature blending” which the Cavity Transfer Mixer will achieve and which we have reported in our previous paper.

Vehicular Ad-hoc Networks (VANETs) is an emerging network technology derived from ad-hoc networks. This paper provides the state-of-the-art of VANETs and provides optimum proposal by improving Quality of Service (QoS.) Today, wireless systems are preferred over wired systems and these are gaining popularity as it provides wireless connectivity to the users irrespective of their geographic position, VANET is one of them. VANETs are installed to minimize the risk of road accidents and to improve passenger comfort by permitting the vehicles to exchange various types of data. In this paper, the Signal Strength based Optimum Path Selection (SSOPS) based solution on how to mitigate the QoS issues that exists while using the existing methods are discussed. Moreover, the solution has been tested using NS2 software using various parameters.

AbstractA system setup for measurements of acoustic field, together with the results of 3D visualisations of acoustic energy flow are presented in the paper. Spatial sampling of the field is performed by a Cartesian robot. Automatization of the measurement process is achieved with the use of a specialized control system. The method is based on measuring the sound pressure (scalar) and particle velocity(vector) quantities. The aim of the system is to collect data with a high precision and repeatability. The system is employed for measurements of acoustic energy flow in the proximity of an artificial head in an anechoic chamber. In the measurement setup an algorithm for generation of the probe movement path is included. The algorithm finds the optimum path of the robot movement, taking into account a given 3D object shape present in the measurement space. The results are presented for two cases, first without any obstacle and the other - with an artificial head in the sound field.
