This paper deals with the optimization of maximum power point tracking when a photovoltaic panel is modelled as two diodes. The adopted control is implemented using a sliding mode control (SMC) and the optimization is ...

A new coordinate search method for bound constrained optimization isintroduced. The proposed algorithm employs coordinate directions, ina suitable way, with a nonmonotone line search for accepting the newpoint, without ...

Contextual information extracted from the user task can help to better target retrieval to task-relevant content. In particular, topical context can be exploited to identify the sub- ject of the information needs, contributing ...

The concept of pattern conception was discussed for categorization of data mining architectures. The difference between pattern conception and pattern recognition models lead to the categorization of information processing ...

This article presents a method for the Maximum Power Point Tracking (MPPT) of a Photovoltaic (PV) panels array with partial shading, applying an Improved Pattern Search Method (IPSM). The method is simulated in PSIM @ and ...

We design a fast ray tracing technique to simulate the response of seismic sources located at depth such as passive data due to fluid injection, hydraulic fracturing, volcanic tremors or earthquakes, with receivers located ...

Object tracking is one of the main fields within computer vision. Amongst various methods/ approaches for object detection and tracking, the background subtraction approach makes the detection of object easier. To the ...

En esta tesis doctoral presentamos y desarrollamos dos nuevos modelos de optimización sin derivadas. En primer lugar, proponemos un nuevo método de búsqueda de patrones para optimización local, denominado algoritmo nmps, ...

The current work presents a novel hybrid approach for motion estimation of various video sequences with a purpose to speed up the entire process without affecting the accuracy. The method integrates the dynamic Zero motion ...
