In this paper a segmented video codec with hybrid motion estimation and inherent bit rate control capability is presented. The first frame in the data is always encoded in intraframe mode, while the rest of the frames are encoded in interframe mode. The interframe encoding is based on (1) hybrid conventional/perspective block motion vector estimation and coding, and (2) coding of the prediction...

Cardiac arrhythmias, caused by disorders in the generation and transmission of cardiac impulses, is included among the heart disorders that cause inefficient blood circulation. The most commonly-used method for diagnosing this disorder is electrocardiography. In this study, we aimed to identify and diagnose different types of arrhythmia prevalent among the seemingly-healthy horses of Sanandaj C...

In this paper we describe a simple method to implement two block-coded modulation (BeM) families previously reported by the present authors. This method considerably simplifies the bit mapping procedure, and makes it possible to implement the two BeM families with long block lengths and large signal alphabets. Next, we address the problem of rotationally invariant code design that is necessary ...

ABSTRACT -Automated analysis of ECG signals has evolved over a period of time to provide very sophisticated system analysis and interpretations. As the demand in the medical field is moving towards fully automated and intelligent systems, better technology and methods are required to interpret the abnormalities of body, especially of heart. Abnormal rhythms like LBBB and RBBB may not be life th...

A novel organic-inorganic hybrid of triethanolamine linked covalently with a new building block of {VMo6O25} was synthesized in aqueous solution, and the hybrid was further assembled with copper-triethanolamine complexes to form a ring-like structure. This work represents an advance in the organic functionalization of polyoxometalate performed in aqueous solution instead of an organic solvent.

The block GMRES (BGMRES) method is a natural generalization of the GMRES algorithm for solving large nonsymmetric systems with multiple right-hand sides. Unfortunately, its cost increases significantly per iteration, frequently rendering the method impractical. In this paper we propose a hybrid block GMRES method which offers significant performance improvements over BGMRES. This method uses th...

An earlier paper by the same author suggested combining a block cipher and a stream cipher to get a strong hybrid cipher. This paper proposes a specific cipher based on those ideas, using the HC-128 stream cipher and a tweakable block cipher based on Serpent. Table of

In this work, we will compare two approximation method based on hybrid Legendre and Block-Pulse functions and a computational method for solving nonlinear FredholmVolterra integral equations of the second kind which is based on replacement of the unknown function by truncated series of well known Block-Pulse functions (BPfs) expansion.
