In this paper, the experimental design and computer simulation model of a multi-effect humidification/dehumidification (MEH) solar desalination system has been presented. The pilot plant on MEH was designed, fabricated and tested at the Center for Energy Studies, Indian Institute of Technology Delhi, India. The heat collection part has been designed to provide continuously the hot water to the ...

Generalized distillation framework has been shown to be effective in speech enhancement in the past. We extend this idea to speaker normalization without any explicit adaptation data in this paper. In the generalized distillation framework, we assume the presence of some “privileged” information to guide the training process in addition to the training data. In the proposed approach, the privil...

in this article, we survey the asymptotic stability analysis of fractional differential systems with the prabhakar fractional derivatives. we present the stability regions for these types of fractional di fferential systems. a brief comparison with the stability aspects of fractional differential systems in the sense of riemann-liouville fractional derivatives is also given.

in this paper, boundary value problems of fractional order are converted into an optimal control problems. then an approximate solution is constructed from translations and dilations of a b-spline function such that the exact boundary conditions are satisfied. the fractional differential operators are taken in the riemann-liouville and caputo sense. several example are given and the optimal err...

The compostion of the oils from flower and leaf of Achillea mellifolium L. subsp. mellifolium were collected during the flowering priod from Lar area to Damavand montain, altitude 3400 m in July 2003. The essential oils obtained by different methods of distillation (steam distillation and hydro-distillation), the percentage of oils for flower and leaf by steam distillation were 0.2 and 0.05% an...

Gaussian processes (GPs) are flexible models that can capture complex structure in large-scale dataset due to their non-parametric nature. However, the usage of GPs in real-world application is limited due to their high computational cost at inference time. In this paper, we introduce a new framework, kernel distillation, for kernel matrix approximation. The idea adopts from knowledge distillat...

Compositions measurement is a vitally critical issue for the modelling and control of distillation process. The product compositions of distillation columns are traditionally measured using indirect techniques via inferring tray compositions from its temperature or by using an online analyser. These techniques were reported as inefficient and relatively slow methods. In this paper, an alternati...

The paper considers the effect of feed plate location on the interactions in a seven plate binary distillation column. The mathematical model of the distillation column is deduced based on the equations of mass and energy balances for each stage, detailed model for both reboiler and condenser, and heat transfer equations. The Dynamic Relative Magnitude Criterion, DRMC is used to assess the inte...

The structure of the thermally coupled distillation systems offers some control challenges arising from the transfer of vapor (or liquid) streams between the columns. In particular, the presence of recycle streams for coupled schemes has influenced the notion that control problems might be expected during the operation of those systems with respect to the rather well-known behavior of conventio...

This study aimed to develop a new processing method for the effective use of rice shochu distillation remnants. We examined the inhibitory effects on the growth of human lung carcinoma cells in the medium of rice shochu distillation remnants with various fungi. Interestingly, high inhibitory effects on the growth of human lung carcinoma cells in the medium of rice shochu distillation remnants w...
