In this paper, a simulation model based on the non-stoichiometric equilibrium method via ASPEN Plus was established to analyze gasification performance of 20 herbaceous and agricultural biomasses (H&ABs) linked with syngas fermentation product purification units for ethanol production. The does not consider system as black box; it focuses important processes in such drying, pyrolysis, gasif...

This paper aims to optimize the Central Bank transparency level which corresponds to the minimum of output volatility in 28 states of the Organization of Islamic Cooperation (due to the maximum data availability) during the period 2003-2014. For this purpose, the Dincer-Eichengreen index is used, which includes five aspects covering political, economic, procedural, policy, and operational trans...

OBJECTIVE Diminished cardiac high-energy phosphate metabolism (phosphocreatine-to-ATP (PCr:ATP) ratio) and cardiac power with age may play an important roles in development of cardiac dysfunction and heart failure. The study defines the impact of age on PCr:ATP ratio and cardiac power and their relationship. METHODS Thirty-five healthy women (young≤50 years, n=20; and old≥60 years, n=15) unde...

Low latency, high data speeds, and a higher degree of perceived service quality for consumers base station capacity are only some the advantages fifth generation (5G) mobile communications. This paper focuses on design precoding system downlink transmission multi-user multiple-input multiple-output (MU-MIMO). For MU-MIMO systems, traditional techniques investigated difficult since transmitter m...

Cost-utility of vagus nerve stimulation (VNS) therapy for medically refractory epilepsy–—An update Dear Sir, In a previous health technology assessment, the cost-utility of VNS therapy was calculated as £28,849 per quality-adjusted life year (QALY) gained. 1 This economic model assumed that the device's life expectancy was at best 5 years, and that the number needed to treat was 6 to produce on...

we design and simulate a five-port optical router, which is composed of twenty mach-zehnder-based switching elements and twelve waveguide crossings for use in integrated photonic interconnection networks. we simulated and analyzed the operation of the proposed optical router from the aspects of insertion loss, power budget, q-factor and the minimum bit error ratio by use of optisystem simulator...

The aim of this research is to get a better understanding of the electrolytic refining process in order to yield the anode slime. Three types of secondary copper anodes are electro refined in an electrolytic system, where the electrolyte is an acid of copper sulphate solution. As a result of the electro-refining process the anode slime has been gained as secondary product. The experimental ...

This paper investigates the effect of the variation of duty ratio on the different performance parameters of the three non-isolated dc-dc converters namely buck, boost and buck-boost converter. Five important parameters dependent on the duty ratio have been identified namely output voltage, output current, effective impedance at the input, minimum inductance and minimum capacitance for continuo...
