In the sequel to [12], we discuss behavioural approach for linear, time-varying, differential algebraic (descriptor) systems with real analytic coefficients. The analysis is “almost global” in the sense that the analysis is not restricted to an interval I ⊂ R but is allowed for the “time axis” R\T, where T is a discrete set of critical points, at which the solution may exhibit a finite escape t...

in order to study the morphological, phenological and yield characteristics of 70 desi chickpea genotypes, a trial was conducted on 2007 in research farm of agriculture faculty of ferdowsi university of mashhad. in this study, 70 desi chickpea genotypes from ferdowsi university of mashhad seed bank, were planted in plots without replication including one to four planting rows at maximum length ...

a common method to determine the order of minimal realization of a continuous linear time invariant descriptor system is to decompose it into slow and fast subsystems using the weierstrass canonical form. the weierstrass decomposition should be avoided because it is generally an ill-conditioned problem that requires many complex calculations especially for high-dimensional systems. the present ...

This chapter focuses on the problem of recovering a hyperspectral image descriptor based upon harmonic analysis. It departs from the use of integral transforms to model hyperspectral images in terms of probability distributions. This provides a link between harmonic analysi and affine geometric transformations between object surface planes in the scene. Moreover, the use of harmonic analysis pe...

We present a mathematical model to decompose longitudinal deformation into normal and abnormal components. The goal is detect extract subtle from periodic motions in video sequence. It has important applications medical image analysis. To achieve this goal, we consider representation of the deformation, called Beltrami descriptor, based on quasiconformal theories. descriptor complex-valued matr...

We present a new document image descriptor based on multi-scale runlength histograms. This descriptor does not rely on layout analysis and can be computed efficiently. We show how this descriptor can achieve state-of-theart results on two very different public datasets in classification and retrieval tasks. Moreover, we show how we can compress and binarize these descriptors to make them suitab...

Motion trajectory contains plentiful of motion information which is useful for motion analysis in many tasks. Motion recognition via trajectory is important in motion analysis for many human and robotic tasks. An effective descriptor for motion trajectories plays an important role in the recognition algorithm. In this paper, we propose a new descriptor with a modified data alignment method for ...
