it is several decades that the application of membrane processes for gas separation has become a great concern within industries. among them, the polymeric membranes of different structures have played the most important role. such application has been widely extended to gas separation and due to the necessity of both; prediction of the behavior of these processes and recognition of the effecti...

The concepts of separation index of a graph and of a surface are introduced. We prove that the separation index of the sphere is 3. Also the separation index of any graph faithfully embedded in a surface of genus g is bounded by a funtion of g. 2002 Wiley Periodicals, Inc. J Graph Theory 41: 53–61, 2002 1. GRAPH ISOMORPHISM This first section on the Graph Isomorphism Problem is meant only as mo...

The game of Go is an ancient two-player complete information game. It is yet unknown how to write strong playing programs for the game of Go, despite a lot of efforts . The usual approach that some of the best current programs use is based on a decomposition of the game into simpler sub-games. Examples of some of these well-known sub-games are the capture game, the connection game, the eye game...

Separation logic [20,21,14] began life as an extended formalisation of Burstall’s treatment of list-mutating programs [8]. It rapidly became clear that there was more that it could say: O’Hearn’s discovery [13] of ownership transfer of buffers between threads and Boyland’s suggestion [5] of permissions to deal with variable and heap sharing pointed the way to a treatment of safe resource manage...

separation system is one of the most important systems in rockets. the influence of this system on mission success cannot be ignored. in this paper, reliability of a sounding rocket separation system is determined using block diagram and fmea . this system is based on the flexible linear shape charge cross-section and a spring mechanism to accelerate separation. in this investigation, the relia...

This supplementary document includes the following sections. Section 1 describes another multiplexed illumination method using a multiplexing scheme similar to that in Lemma 4.1 in the paper. The method also extracts N direct illuminations from 2N + 1 images. Section 2 shows detailed derivation of the SNR analysis results. Section 3 discusses about the pros and cons of direct/global separation ...
