Information distillation aims to analyze and interpret large volumes of speech and text archives in multiple languages and produce structured information of interest to the user. In this work, we investigate cross-lingual information distillation, where nonEnglish (source language) documents are searched for user queries that are in English (target language). We propose to perform distillation ...

The stringent quality requirement of petroleum products in highly competitive markets makes on-line controlling of distillation composition essential. In this paper, a novel method using sensitivity matrix analysis and kernel ridge regression to implement on-line estimation of distillation compositions is proposed. In the approach, the sensitivity matrix analysis is presented to select the most...

A new, general method for the determination of batch distillation regions of heteroazeotropic distillation is suggested. The method proposed, which means the extension of the method of Pham and Doherty, takes into consideration the possibility of the withdrawal of any fraction of either liquid phase from the decanter as distillate. The simplified and rigorous simulation calculations were carrie...

INTRODUCTION In Japan, Pilot Plant of the HIDiC was built in 2005. It was commercial base scale and already achieved the consecutive distillation for 1000 hours. The energy consumption of the pilot HIDiC was only about 70% of that of a conventional distillation column. The HIDiC can lower reboiler and condenser load by heat exchange between rectifying section and stripping section. Therefore, i...

The synthesis of complex distillation columns has remained a major challenge since the pioneering work by [Sargent, R.W.H., & Gaminibandara, K. (1976). Optimal design of plate distillation columns. In L.C.W. Dixon (Ed.), Optimization in action. New York: Academic Press]. In this paper, we first provide a review of recent work for the optimal design of distillation of individual columns using tr...

Packed columns are equipment commonly found in absorption, distillation, stripping, heat exchangers and other operations, like removal of dust, mist and odors and for other purposes. Mass transfer between phases is promoted by their intimate contact through all the extent of the packed bed. The main factors involving the design of packed columns are mechanics and equipment efficiency. Among the...

The security of a cryptographic key that is generated by communication through a noisy quantum channel relies on the ability to distill a shorter secure key sequence from a longer insecure one. For an important class of protocols, which exploit tomographically complete measurements on entangled pairs of any dimension, we show that the noise threshold for classical advantage distillation is iden...

When a quantum cryptographic system operates in the presence of background noise, security of the key can be recovered by a procedure called key distillation. A key-distillation scheme effective against so-called individual (bitwise-independent) eavesdropping attacks involves sacrifice of some of the data through privacy amplification. We derive the amount of data sacrifice sufficient to defend...

Background: Thymus daenensis is on e of the endemic aromatic species in Iran that its essential oil is used in food and pharmaceutical industries. Objective: In this study, the effects of plant growth stages and distillation methods on essential oil content and thymol percentage of this species were evaluated. Methods: The aerial parts of Th. daenensis were collected in three stages of plan...

eryngium caucasicum trautv. (apiaceae) is a perennial herbaceous plant with about one meter height, an endemic species that has been distributed in the northern parts of iran. the plant leaves are normally used in medicine and food industries in iran.the plant has several medicinal properties including enforcing generative power, diuretic, lenitive and appetizer. in this research differents par...
