This article proposes a new concept termed "yield analysis" (YA) as a method of extracting a subset of elementary modes (EMs) essential for describing metabolic behaviors. YA can be defined as the analysis of metabolic pathways in yield space where the solution space is a bounded convex hull. Two important issues arising in the analysis and modeling of a metabolic network are handled. First, fr...

Yield-Aware Leakage Power Reduction of On-Chip SRAMs Afshin Nourivand, Ph.D. Concordia University, 2010 Leakage power dissipation of on-chip static random access memories (SRAMs) constitutes a significant fraction of the total chip power consumption in state-ofthe-art microprocessors and system-on-chips (SoCs). Scaling the supply voltage of SRAMs during idle periods is a simple yet effective te...

the yield loss simulation (yls) and the macros liq.csm models were used to simulate the effect of stem borer damage at a detillering rate of 5, 15, 30, 60% at vegetative, panicle initiation and grain filing stages, on yield of rice cultivar?s ratna. this stem borer damage during vegetative and panicle initiation stages was not simulated appropriately by both the models. relatively macros simula...

The purpose of this research work was to investigate the optimum operating conditions for biodiesel production from castor oil using a microwave. The Box–Behnken design of experiment was carried out using the Design Expert 7. A response surface methodology (RSM) was used to analyze the influence of the process variables (molar ratio of methanol to castor oil, catalyst concentration, reaction ti...

Objective: Evaluation activity was conducted using three spearmint genotypes (WG-SPM-Engl, SPM-Fran and SPM-EAS) and one standard check (WGSM-03) at Wondo Genet, Awassa, Debre Zeit and Allagae during 2012 and 2013 for two years. Methods: The treatments were arranged in randomized complete block design with four replications. Data on leaf to stem ratio, leaf yield/ha, Essential oil content and e...

This study aimed to evaluate the performance, some carcass characteristics from feedlot lambs receiving sunflower crushed (SC) in the diet on partial replacement of soybean meal. The experimental design was randomized block with four levels of SC in the diet (0, 10, 20 and 30% of dry matter (DM)). There was a linear reduction of 0.02; 0.003; 0.003 and 0.17% for each percentage unit of added SC ...

Seismic base isolation are devices that used to limit the human and material damage caused by an earthquake. This devices diffuse the energy induced at the time of the earthquake before being transferred to the structure.The base isolated structures when subjected to the near-fault eathquakes which contain long-period velocity pulses that may coincide with the period of base isolated structures...

in this study, yield-water and profit function was used to obtain water demand function in agriculture sector. the results showed that the ratio of actual to potential evapotranspiration had positive, significant effecton the ratio of actual to potential yield for wheat and barley. also, square ratio of actual to potential evapotranspiration had negative, significant relationship. after estimat...
