Cassava constitutes an abundant substrate in tropical regions. The production of butanol in ABE fermentation by Clostridium beijerinckii BA101 using cassava flour (CF) was scaled-up to bioreactor level (5 L). Optimized fermentation conditions were applied; that is, 40℃, 60 g/l CF, and enzymatic pretreatment of the substrate. The batch fermentation profile presented an acidogenic phase for the f...

This article presents an optimization methodology of batch production processes assembled by shared resources which rely on a mapping of state-events into time-events allowing in this way the straightforward use of a well consolidated scheduling policies developed for manufacturing systems. A technique to generate the timed Petri net representation from a continuous dynamic representation (Diff...

In the production of wine distillates, factors influencing their composition, respectively quality, can be divided into following directions: composition grapes (as raw material), technology for its processing and alcoholic fermentation to obtain material, as well method distillation material derive a distillate. Each these is important quality distillate significantly affects concentration che...

An extended dynamic model is presented for a polyesterification reaction in a semi-batch wise operated vessel connected to a distillation column. The developed model describes the effect of polymerization on reactants. The model also contains kinetics describing the change of rate order during the reaction. To improve the predictive capabilities, the model has been extended with advanced thermo...

The performance of extractive (BED) and pressure swing distillation (PSBD) for the separation of the mixture acetone(A)-methanol(B) forming a minimum azeotrope are compared. For the BED, where the solvent(S) is water, three different operational policies (basic, modified, controlled) are studied. For the PSBD the double column batch stripper (DCBS) is applied with and without heat integration (...

The flocculation gene FLO1 was transferred into the robust industrial strain Saccharomyces cerevisiae PE-2 by the lithium acetate method. The recombinant strain showed a fermentation performance similar to that of the parental strain. In 10 repeat-batch cultivations in VHG medium with 345 g glucose/L and cell recycling by flocculation-sedimentation, an average final ethanol concentration of 142...

Self-paced learning and hard example mining re-weight training instances to improve learning accuracy. This paper presents two improved alternatives based on lightweight estimates of sample uncertainty in stochastic gradient descent (SGD): the variance in predicted probability of the correct class across iterations of minibatch SGD, and the proximity of the correct class probability to the deci...

Knowledge distillation has been widely used to produce portable and efficient neural networks which can be well applied on edge devices for computer vision tasks. However, almost all top-performing knowledge methods need access the original training data, usually a huge size is often unavailable. To tackle this problem, we propose novel data-free approach in paper, named Dual Discriminator Adve...
