In the present paper, a new scheme for damping torsional modes in a series compensated power system has been developed. The proposed scheme, utilizes the effectiveness of combined active power and frequency (C.A.P.F.) SVS auxiliary controller in co-ordination with an induction machine damping unit coupled to the T-G shaft. Studies are conducted on the first IEEE benchmark model. The damping sch...

At the present, several applications need to classify high dimensional points belonging to highly unbalanced classes. Unfortunately, when the training set cardinality is small compared to the data dimensionality (‘‘small sample size’’ problem) the classification performance of several well-known classifiers strongly decreases. Similarly, the classification accuracy of several discriminative met...

this paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. the methodology is based on a modified sliding mode observer (smo) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. the faults are reconstructed using the equivalent output error i...

In this paper, we propose a novel shape description method for mobile retrieval of leaf images. In this method, termed multiscale arch height (MARCH), hierarchical arch height features at different chord spans are extracted from each contour point to provide a compact, multiscale shape descriptor. Both the global and detailed features of the leaf shape can be effectively captured by the propose...

Contour polygonal approximation is a simplified representation of a contour by line segments, so that the main characteristics of the contour remain in a small number of line segments. This paper presents a novel method for polygonal approximation based on the Complex Networks theory. We convert each point of the contour into a vertex, so that we model a regular network. Then we transform this ...

Semi Global Boundary Detection (SGBD) breaks the image into scan lines in multiple orientations, segments each one independently, and combines the results into a final probabilistic 2D boundary map. The reason we break the image into scan lines is that they are a mid-level image representation that captures more information than a local patch. Luckily, scan lines are 1D signals that can be opti...

Phase retrieval deals with the estimation of complexvalued signals solely from the magnitudes of linear measurements. While there has been a recent explosion in the development of phase retrieval algorithms, the lack of a common interface has made it difficult to compare new methods against the state-of-theart. The purpose of PhasePack is to create a common software interface for a wide range o...

JUBE considerably reduces the cost of configuring, running and analyzing benchmark suites XML-file based configuration allows a very flexible parameterization Use cases: Procurements, comparison of systems, monitoring effects of system and configuration changes Key concepts and strategy of JUBE: 1. Independence of applications and platforms Provision of templates 2. Span a multi-dimensional par...

Empirical studies are important to evaluate new techniques, methodologies, tools and processes proposed. While the diversity of Software Product Line Engineering (SPLE) approaches is increasingly growing, empirical studies assessing them are still limited, thereby hampering the technology transfer of the field. One of the key reasons for this problem is the lack of support for designing studies...
