In this research, optimization of the integrated biodiesel production process composed transesterification edible sunflower oil, catalyzed by commercial lipase, with simultaneous extraction glycerol from reaction mixture was performed. Deep eutectic solvents (DESs) were used in as and media. For two systems, choline chloride:glycerol (ChCl:Gly) chloride:ethylene glycol (ChCl:EG), respectively, ...
Maximum likelihood estimation of multivariate distributions needs solving a optimization problem with large dimentions (to the number of unknown parameters) but two- stage estimation divides this problem to several simple optimizations. It saves significant amount of computational time. Two methods are investigated for estimation consistency check. We revisit Sankaran and Nair's bivari...
The aim of this study is investigation of TLP variables on microstructure and mechanical properties of Al2024 to Ti-6Al-4V bonding for TLP joint. For this purpose, the sheets were prepared with dimension of 130×32×3 mm from Ti-6Al-4V and Al2024 alloys and 50µm thick Sn-5.3Ag-4.2Bi foil as interlayer. Sn-5.3Ag-4.2Bi foil prepared with dimension of 32×25 mm. Two alloys was joint together by proce...
data envelopment analysis (dea) is a method for measuring the efficiency of peer decision making units (dmus) with multiple inputs and outputs. the traditional dea treats decision making units under evaluation as black boxes and calculates their efficiencies with first inputs and last outputs. this carries the notion of missing some intermediate measures in the process of changing the inputs to...

A two-stage anaerobic digestion (AD) process has been applied to improve the efficiency of methane production from various organic materials. However, performance traditional controllers may be limited by differences in rate biochemical reactions, uncertainties, and consequences interconnection between two bioreactors. In this work, a nonlinear optimization-based control strategy that applies a...
