Raschig Super-Pak is a novel development in structured packing product technology that is fundamentally different to the well known corrugated perforated or nonperforated, textured sheet metal structured packings. It comprises of a systematic sequence of smooth sinusoidal waves above and below the plain of the metal sheet. Total reflux distillation tests with Raschig Super-Pak 300 were conducte...

In Bounded Model Checking (BMC), the search for counterexamples of increasing lengths is translated into a sequence of satisfiability (SAT) checks. It is natural to try to exploit the similarity of these SAT instances by forwarding clauses learned during conflict analysis from one instance to the next. The methods proposed to identify clauses that remain valid fall into two categories: Those th...

Batch distillation is one of the most important unit operations for the small-scale production of specialty and fine chemicals. The so called Middle Vessel Batch Distillation (MVBD) with total reflux offers many advantages compared to conventional batch distillation. It is favourable due to the simultaneous production of three products of high purity. In this work, we present a thorough analysi...

We describe a protocol for distilling maximally entangled bipartite states between random pairs of parties from those sharing a tripartite W state |W=(1/sqrt[3])(|100+|010+|001)(ABC), and show that the total distillation rate E(t)(infinity) [the total number of Einstein-Podolsky-Rosen (EPR) pairs distilled per W, irrespective of who shares them] may be done at a higher rate than EPR distillatio...

We introduce distillation codes, a method for streaming and storing data. Like erasure codes, distillation codes allow information to be decoded from a sufficiently large quorum of symbols. In contrast to erasure codes, distillation codes are robust against pollution attacks, a powerful class of denial of service (DoS) attacks in which adversaries inject invalid symbols during the decoding proc...

We introduce two first-order graph-based dependency parsers achieving a new state of the art. The first is a consensus parser built from an ensemble of independently trained greedy LSTM transition-based parsers with different random initializations. We cast this approach as minimum Bayes risk decoding (under the Hamming cost) and argue that weaker consensus within the ensemble is a useful signa...

Previously, Tanskanen and Pohjola (2000) and Tanskanen and Malinen (2005) have presented a method of rigorous minimum energy calculation for non-ideal multicomponent distillation. The method is based on column simulation with a large number of equilibrium stages to mimic infinitely high columns, and it has been successfully tested with simple distillation column systems. This paper describes a ...

Juniperus horizontalis Moench (Family Cupressaceae), commonly called creeping juniper, is a widely distributed species in the United States and much of Canada. It is potentially a source for two important chemical products, the anticancer drug synthetic precursor, podophyllotoxin and essential oils. The objectives of this study were to ascertain the likelihood of utilizing J. horizontalis needl...

Microwave-assisted hydro distillation MAHD of eucalyptus citriodora. oil was investigated and a comparison was made with conventional hydro distillation. For MAHD, three process parameters; Microwave power, Extraction time and duration of dryness of sample were selected for the extraction. MAHD resulted in a shorter extraction time and better quality of oil compared to that in conventional hydr...

Information distillation aims to extract relevant pieces of information related to a given query from massive, possibly multilingual, audio and textual document sources. In this paper, we present our approach for using information extraction annotations to augment document retrieval for distillation. We take advantage of the fact that some of the distillation queries can be associated with anno...
