A synchronous ion separation and electricity generation process has been developed using G-O membranes. In addition to the size effect proposed prevsiouly, the separation of ions can be attributed to the different interactions between ions and G-O membranes; the generation of electricity is due to the confinement of G-O membranes, and the mobility difference of ions. Efficient energy transducti...

The lift-and-project closure is the relaxation obtained by computing all lift-and-project cuts from the initial formulation of a mixed integer linear program or equivalently by computing all mixed integer Gomory cuts read from all tableau’s corresponding to feasible and infeasible bases. In this paper, we present an algorithm for approximating the value of the lift-and-project closure. The orig...

We present in this paper a general decomposition framework to solve exactly adjustable robust linear optimization problems subject to polytope uncertainty. Our approach is based on replacing the polytope by the set of its extreme points and generating the extreme points on the fly within row generation or column-and-row generation algorithms. The novelty of our approach lies in formulating the ...

Blends of electron-donating and -accepting organic semiconductors are widely used as photoactive materials in next-generation solar cells and photodetectors. The yield of free charges in these systems is often determined by the separation of interfacial electron-hole pairs, which is expected to depend on the ability of the faster carrier to escape the Coulomb potential. Here we show, by measuri...

A next-generation air traffic decision support tool, known as the Active Final Approach Spacing Tool (aFAST), will generate heading, speed and altitude commands to achieve more precise separation of aircraft in the terminal area. The techniques used to analyze the performance of earlier generation decision support tools are not adequate to analyze the performance of aFAST. This paper summarizes...

The coupled numerical simulation of flow and sound generation in a simplified vocal tract model of sibilant /s/ were validated with experimental measurements. The simplified model consists of incisors and four rectangular channels representing a throat, constriction, space behind the incisors, and lips. Velocity distribution and far-field sound were measured by a hot-wire anemometer and an acou...

In recently proposed multiple access techniques like IDMA and OFDM-IDMA, the user separation is done by user specific interleavers in contrast to the conventional CDMA scheme, where user separation is assured with user-specific signature sequences. The user specific interleavers must demonstrate minimum probability of collision amongst each other in addition to other merits, including minimal c...

P-sets (P stands for Packet), a set pair with dynamic and law characteristics, are made up of an internal outer P-set, which is obtained by introducing characteristics into the Cantor improving set. The concepts αF-sub-information, αF¯-sub-information, (αF,αF¯)-sub-information presented in this paper based on P-sets, it then suggested that relationship between generation sub-information its att...

In response to global efforts combat climate change, many research have contributed upgrading cryogenic distillation, an energy-intensive petrochemical operation, especially for olefin/paraffin separation. Metal-organic framework (MOF) membranes can be a competitive candidate this purpose. work, we reviewed the main progress of MOF separations, with focus on potential ZIF-8 C 3 H 6 /C 8 Membran...

Daily separation of rat pups from their mothers while the preweaning period has an impact on behavior and stress response of pups. We hypothesized that maternal separation may create a depression-like state in mother rats from which we separate the rat pups and decrease their reproductive function and fertility. Also, we aimed to evaluate the transmission degree of depression and anxiety across...
