In this paper modified ARQ (automaticrepeat-request) techniques based on turbo coding are investigated for asynchronous DS-CDMA (directsequence code-division multiple-access) data networks under shadowing and frequency selective fading channel conditions. The throughput, delay, and energy efficiency performance of standard ARQ, metric combining, and RCPT (rate compatible punctured turbo) coded ...

The present study aimed at assessing mechanical and durability characteristics of ground granulated blast furnace slag (GGBS)-based geopolymer composites 5%, 10%, 15%, 20%, 25%, 30% replacement proportion silica fume 12 molarity NaOH. Mechanical properties were assessed using compression tension tests, whereas evaluated ultrasonic pulse velocity test (UPV), acid test, rapid chloride permeabilit...

OFDM, MC-CDMA and DS-CDMA are being researched vigorously as the prospective signaling technique for the next generation mobile communications systems, which will be characterized by the broadband packet technology. With packet transmissions, hybrid ARQ (HARQ) will be inevitable for error control. HARQ with rate compatible punctured turbo (RCPT) codes is one of the promising techniques. Data ra...

The cells from plasmacytomas induced in BALB/c and susceptible BALB/c congenic strains of mice by pristane (2,6,10,14-tetramethylpentadecane) (1) have non-random chromosomal translocations, rcpt (6;15) or rcpt(12;15) (2, 3). To date, the karyotypes of 27 early transfer generation or primary pristine-induced plasmacytomas have determined, and 26 of the tumors have either rcpt(6; 15) or rcpt(12;1...

One of the largest theoretical uncertainties assigned to the strong coupling constant αs as determined from hadronic tau decays stems from the differences in the results for Fixed Order Perturbation Theory (FOPT), Contour Improved Perturbation Theory (CIPT) and Renormalon Chain Perturbation Theory (RCPT). It is often argued that the three methods differ in the treatment of higher orders only an...

This paper presents an embedded joint source-channel coding scheme of speech. The source coder is an embedded variable bit rate perceptually based sub-band coder producing bits with different error sensitivities. The channel encoder is a Rate Compatible Punctured Trellis code (RCPT) which permits rate variability and unequal error protection by puncturing symbols. Furthermore, RCPT code design ...

BACKGROUND/AIMS Carnitine palmitoyl-transferase I (CPT I) catalyses the synthesis of long-chain (LC)-acylcarnitines from LC-acyl-CoA esters. It is the rate-limiting enzyme of mitochondrial fatty acid beta-oxidation (FAO) pathway and its activity is regulated by malonyl-CoA. The antiepileptic drug valproic acid (VPA) is a branched chain fatty acid that is activated to the respective CoA ester in...

In recent years, nano-sized graphene oxide (GO) has come to the fore as a promising material for enhancing mechanical and durability performance of cementitious composites. On other hand, partial substitution industrial wastes by-products into composites attracts attention researchers in order ensure long-term sustainability. combine these two aspects, main focus this study is examine effect 0....
