In many distributed applications, pairs of queries and values are evaluated by participating nodes. This includes keyword search for documents, selection queries on tuples, and publish-subscribe. These applications require that all values accepted by the query be evaluated. To carry out this evaluation we will present the peer-to-peer based Bit Zipper Rendezvous which partitions query-value pai...

A variable bit rate characteristic waveform interpolation (VBR-CWI) speech codec with about 1.86kbps average bit rate which combines closed-loop multimode techniques is presented in this paper. Each kind of characteristic waveform (CW) surface is regarded as only rapidly evolving waveforms (REWs), only slowly evolving waveforms (SEWs) or mixed REWs plus SEWs in different cases of CWs evolving p...

This paper proposes a complete compression and coding scheme for onboard satellite applications considering the main on-board constraints: low computational power and easy bit-rate control. The proposed coding scheme improves the performance of the current CCSDS recommendation (Consultative Committee for Space Data Systems) for a low additional complexity. We consider post-transforms in the wav...

Every machine plays roles of client and server simultaneously in a peer-to-peer (P2P) network. Though a P2P network has many advantages over traditional client-server models regarding efficiency and fault-tolerance, it also faces additional security threats. Users/IT administrators should be aware of risks from malicious code propagation, downloaded content legality, and P2P software’s vulnerab...

Due to the cloud coverage of remote-sensing images, ground object information will be attenuated or even lost, and texture spectral image changed at same time. Accurately detecting clouds from images is great significance field remote sensing. Cloud detection utilizes semantic segmentation classify pixel level. However, previous studies have focused on improvement algorithm performance, little ...

Error-correcting output codes (ECOCs) represent classes with a set of output bits, where each bit encodes a binary classiication task corresponding to a unique partition of the classes. Algorithms that use ECOCs learn the function corresponding to each bit, and combine them to generate class predictions. ECOCs can reduce both variance and bias errors for multiclass classiication tasks when the ...

In this paper, we propose and analyze the bit error performance of a generalized selection combining (GSC) receiver for M -ary noncoherent frequency shift keying (NCFSK) signals on i.i.d. Rayleigh fading channels with L antennas at the receiver. For each of the M hypotheses, the receiver combines the K largest outputs among the L available square-law detector outputs before proceeding to the bi...

UNLABELLED We introduce a new forward-time simulator, Admix'em, that allows for rapid and realistic simulations of admixed populations with selection. Complex selection can be achieved through user-defined fitness and mating-preference probability functions. Users can specify realistic genomic landscapes and model neutral SNPs in addition to sites under selection. Admix'em is designed to simula...

In this paper, the authors prove that the differential space-time modulation techniques proposed in literature provide a full spatial diversity. Based on that, the authors propose an antenna selection scheme called general N -out-of-M antenna selection technique for wireless communications channels utilizing differential space-time modulation. The simulation shows that differential detection as...
