Recently, energy procurement by renewable sources has increased. In particular, as solar power generation a high penetration rate among them, radiation predictions at the site are attracting much attention for efficient operation. Various approaches have been proposed to forecast accurately. hybrid models improve performance through forecasting in frequency domain using past radiation. Since da...

The architecture for very-high speed DAC with medium oversampling and high resolution is discussed. The scheme uses an hybrid sigma-delta scheme that processes LSBs of the input word and obtain digital to analog conversion with an hybrid current steering DAC with dynamic element matching of MSBs and time interleaved conversion of LSBs. The return-to-zero for all elements ensures the required li...

Considering the recent emergence of "hybrid biotype" and "El Tor variant", we propose to redefine the biotyping scheme for Vibrio cholerae O1 serogroup. The existing biotyping scheme has limitations and causes confusion as many of the hybrid biotype and El Tor variant strains have phenotypic and genetic changes. A revised biotyping scheme will play a significant role to understand the ecology, ...

In this paper, we evaluate the performance of the hybrid automatic repeat request (ARQ) scheme combined with adaptive coding in satellite communication systems. A cross-layer design which combines the ARQ scheme in the data link layer and adaptive coding and modulation in the physical layer is very important to maximize system throughput and/or performance. Due to the long round trip delay in s...

This paper considers the idea that other schemes besides asymmetric encryption schemes can benefit from a formalisation of the principles of hybrid cryptography. The main focus of research in hybrid cryptography has been in producing efficient asymmetric encryption schemes. Not only have several schemes been proposed, but also a generic method of constructing hybrid encryption schemes from lowe...
