BACKGROUND Compared to expert malaria microscopy, malaria biomarkers such as Plasmodium falciparum histidine rich protein-2 (PfHRP-2), and PCR provide superior analytical sensitivity and specificity for quantifying malaria parasites infections. This study reports on parasite prevalence, sick visits parasite density and species composition by different diagnostic methods during a phase-I malaria...

The higher integration technologies made it possible for accessing any device so fast that within a fraction of seconds the job can be performed. Now days fast memories exists everywhere during accessing if any error happens that has to be detected and corrected within a fraction of microseconds that is made possible with help high performance error correcting codes(ECCs) such as LDPC and Turbo...

Low Density Parity Check (LDPC) codes are one of the best error correcting codes that enable the future generations of wireless devices to achieve higher data rates with excellent quality of service. This paper presents two novel flexible decoder architectures. The first one supports (3, 6) regular codes of rate 1/2 that can be used for different block lengths. The second decoder is more genera...

Candidatus Liberibacter asiaticus (CLas) is a phloem-limited bacterium transmitted by the Asian citrus psyllid, Diaphorina citri, and the presumptive causal agent of citrus greening disease. The current method of detection for CLas within plant and insect samples is by a presence/absence qPCR assay using the CLas 16S rDNA gene target. Although qPCR is highly sensitive, low bacterial titers or s...

this paper presents a low-cost compact planar microstrip-fed monopole antenna and its four-element array design for ultra-wideband (uwb) wireless communication and target detection applications, respectively, operating in the frequency span of 3 ghz to 11 ghz. a prototype was fabricated and then measured based on optimal parameters. the results of reflection coefficient (s11) and radiation patt...

This paper introduces a new field programmable gate array (FPGA) based stochastic low-density parity-check (LDPC) decoding process, to implement fully parallel LDPCdecoders. The proposed technique is designed to optimize the FPGA logic utilisation and to decrease the decoding latency. In order to reduce the complexity, the variable node (VN) output saturated-counter is removed and each VN inter...

Radar electronics developed for past JPL space missions historically had been custom designed and as such, given budgetary, time, and risk constraints, had not been optimized for maximum flexibility or miniaturization. To help reduce cost and risk of future radar missions, a “generic” radar module was conceived. The module includes a 1.25-GHz (L-band) transceiver and incorporates miniature high...
