A silicon-based microscale distillation chip was fabricated consisting of a micro-channel 600 μm in width and 40 cm in length. Micropillars were incorporated in the micro-channel to direct liquid flow from the cooled to the heated end by capillarity. A feed of a 19 mol% acetone-water mixture was separated to 95+ mol% acetone in the distillate and 11 mol% in the bottom stream. This distillation ...

We consider the problem of dictionary matching in a stream. Given a set of strings, known as a dictionary, and a stream of characters arriving one at a time, the task is to report each time some string in our dictionary occurs in the stream. We present a randomised algorithm which takes O(log log(k +m)) time per arriving character and uses O(k logm) words of space, where k is the number of stri...

The timing of downstream migration and detection rates of hatchery-reared Atlantic salmon Salmo salar smolts and stream-reared smolts (stocked 2 years earlier as fry) were examined in the Connecticut River (U.S.A.) using passive integrated transponder (PIT) tags implanted into fish and then detected at a downstream fish bypass collection facility at Turners Falls, MA (river length 192 km). In t...

WG is a synchronous stream cipher submitted to the hardware profile of eSTREAM project. The main feature of this stream cipher is the use of WG transformation. WG uses keys and initial vectors (IVs) of the same lengths 80, 96, 112 and 128 bits. Moreover, IVs of the length 32 and 64 bits are admitted. The most important key recovery attack on WG was presented by Wu and Preneel and uses the weakn...

Usually, in monitoring a proportion p < /em>, the binary observations are considered independent; however, in many real cases, there is a continuous stream of autocorrelated binary observations in which a two-state Markov chain model is applied with first-order dependence. On the other hand, the Bernoulli CUSUM control chart which is not robust to autocorrelation can be applied two-sided co...

Gas mixing in a T-shape micro mixer has been simulated using the Direct Simulation Monte Carlo (DSMC) method. It is considered that the adequate mixing occurs when the mass composition of the species, CO or N2, deviates below 1 % from their equilibrium composition. The mixing coefficient is defined as the ratio of the mixing length to the main channel’s height. As the inlet Kn increases, while ...

Abstract: Aim The objectives of this study were to evaluate which allometric measurements Leptonema larvae are most suitable in order develop mathematical equations describe biomass relationships for the population taxon a reference condition headwater stream. Methods We measured four body dimensions (body length, interocular distance, horizontal width cephalic capsule and vertical capsule) 65 ...
