A New Approach for Modelisation of Ellipsoidal-based Shape

A New Implementation of Maximum Power Point Tracking Based on Fuzzy Logic Algorithm for Solar Photovoltaic System

In this paper, we present a modeling and implementation of new control schemes for an isolated photovoltaic (PV) using a fuzzy logic controller (FLC). The PV system is connected to a load through a DC-DC boost converter. The FLC controller provides the appropriate duty cycle (D) to the DC-DC converter for the PV system to generate maximum power. Using FLC controller block in MATLABTM/Simulink e...

Using Ellipsoidal Harmonics for 3D Shape Representation and Retrieval

A novel approach for 3D Shape description, applicable for search and retrieval applications, based on the theory of Ellipsoidal Harmonics is presented in this paper. The Ellipsoidal Harmonics are appropriately adopted in order to describe volumetric represented 3D objects. The experimental results, performed in a complete 3D object database, prove the efficiency of the proposed approach.

New Fuzzy Modelisation and Control Strategy of Random Disturbances

Analytical Solution for a Two-Layer Transversely Isotropic Half-Space Affected by an Arbitrary Shape Dynamic Surface Load

The dynamic response of a transversely isotropic, linearly elastic layer bonded to the surface of a half-space of a different transversely isotropic material under arbitrary shape surface loads is considered. With the help of displacements and stresses Green’s functions, an analytical formulation is presented for the determination of the displacements and stresses at any point in both surface l...

A New Approach for Obtaining Settling Velocity in a Thickener Using Statistical Regression: A Case Study

In this research work, the parameters affecting the settling velocity within the thickeners were studied by introducing an equivalent shape factor. Several thickener feed samples of different densities including copper, lead and zinc, and coal were prepared. The settling tests were performed on the samples, and the corresponding settling curves were plotted. Using the linear regression analysis...
