This research study proposes Hybrid Encryption System using new public key algorithm and private key algorithm. A hybrid cryptosystem is one which combines the convenience of a public-key cryptosystem with the efficiency of a symmetrickey cryptosystem. Here, we propose a provably two way secured data encryption system, which addresses the concerns of user’s privacy, authentication and accuracy....

understanding the relationship between sink and source in maize is of prime importance in maize growing regions. in this study, a field experiment was carried out during spring and summer 2007 in the experimental field of the college of agriculture, shiraz university, to examine the effects of source restriction (defoliation) on sink size (yield and its components) of  sc704 maize hybrid.  a fa...

This work deals with model following by output feedback in hybrid systems subject to periodic state jumps. In particular, the hybrid systems addressed exhibit a free jump dynamics and a to-be-controlled flow dynamics. Moreover, they may present a direct algebraic link from the control input to the regulated output — such possible algebraic link is briefly called the control feedthrough. The pro...

This paper proposes improved schemes for hybrid STBC systems. The hybrid space-time block codes (STBC) system is a combination of STBC scheme and SM scheme. It is aimed to obtain both diversity gain and spectral efficiency gain. In hybrid STBC, conventional schemes can’t achieve good BER performance of STBC symbols due to interference from other symbols. The proposed scheme improves BER perform...

Herein, we report a simple fabrication of hybrid nanowires (NWs) composed of a p-type conjugated polymer (CP) and n-type inorganic quantum dots (QDs) by exploiting the crystallization-driven solution assembly of poly(3-hexylthiophene)-b-poly(2-vinylpyridine) (P3HT-b-P2VP) rod-coil amphiphiles. The visualization of the crystallization-driven growth evolution of hybrid NWs through systematic tran...

It is well known that a block FFT implementation of convolution is vastly more efficient than the direct form FIR filter. Unfortunately, block processing incurs significant input/output latency which is undesirable for real-time applications. A hybrid method is proposed for doing convolution by combining direct form and block FFT processing. The result is a zero latency convolver that performs ...

twenty local and foreign maize (zea mays l.) hybrids in five different maturity groups were evaluated in mashhad, iran for two years (2007-2009). three planting dates (5th may, 20th may and 5th june) and hybrids were arranged in a randomized complete block design as split plot arrangements, with three replications. the planting dates were in main plots and hybrids in subplots. the results indic...

Block fading is a popular channel model that approximates the behavior of different wireless communication systems. Automatic-Repeat Request (ARQ) protocols are used to provide reliable communications in wireless networks. In this paper, the throughput of basic and hybrid ARQ protocols over Rayleigh block fading channels is derived. The throughput is computed for different modulation schemes an...

We present a novel error-concealment method for MPEG-2 video decoders. Imperfect transmission of block-based compressed images may result in loss of blocks, making image degradation inevitable. In the hybrid error-concealment method, both spatial and temporal error concealment repair the damaged regions through adaptive interpolation in the respective domains. In order for the hybrid method to ...

A novel hybrid mesoporous material functionalized with carboxy groups was synthesized by self-assembly of a novel building block consisting of a cubic siloxane unit and a long organic chain with an ester bond and the following hydrolysis of ester bonds, representing a promising approach to designing hybrid structures at both molecular and mesoscopic scales.
