The objective of this study was to optimise the extraction conditions for phenolic compounds from neem (Azadirachta indica) leaves using response surface methodology (RSM). A central composite rotatable design (CCRD) was applied to determine the effects of acetone concentration (%), extraction time (mins), and extraction temperature (oC) on total phenolic content (TPC) from neem (Azadirachta in...

Following the trend of turbo codes and low density parity check (LDPC) codes, single-parity turbo product codes (TPC/SPC) are being seriously considered for application in future high-density recording systems. Recent work on TPC/SPC codes has focused on ideal partial response channels with additive white Gaussian noise. This work extends the investigation to a more realistic equalized Lorentzi...

The TPC-H benchmark proved to be successful in the decision support area. Many commercial database vendors and their related hardware vendors used these benchmarks to show the superiority and competitive edge of their products. However, over time, the TPC-H became less representative of industry trends as vendors keep tuning their database to this benchmark-specific workload. In this paper, we ...

In Wireless Sensor Networks (WSNs), many techniques have been proposed to reduce the energy consumption. Among them, one of the outstanding methods is the transmission power control (TPC). In this paper, we propose a TPC scheme that can be easily implemented in IEEE 802.15.4 standard. The simulation results demonstrated that our TCP scheme is effective in conserving energy and can be used in WS...

This note describes a study on the momentum resolution of the TPC-based central tracker design which will be included in the ECFA/DESY conceptual design report (CDR) for the proposed DESY 500 GeV electron-positron linear collider. The study found it to be likely that the central tracker could achieve a momentum resolution of approximately 10 −4 (GeV/c) −1 , particularly if a layer of silicon mi...

In this paper, we present an implementation of a turbo product codes (TPC) decoder achieved on a novel Reconfigurable Multimedia Accelerator (RMA). The RMA is based on the principle of hierarchical shared memory storage managed through a dedicated local controller favoring high data throughput, while squeezing round-trip memory latencies. The mapping methodology facilitates the characterization...

We have operated for the first time a liquid-argon TPC immersed in a magnetic field up to 0.55 tesla. We show that the imaging properties of the detector are not affected by the presence of the magnetic field. The magnetic bending of the ionizing particle allows one to discriminate their charge and estimate their momentum. These figures have up to now not been accessible in the non-magnetized l...
