The Potential of Nanoparticles for Upgrading Thin Film Nanocomposite Membranes – A Review

Over the past decade, many applications were intended for filtration by membrane technology especially the thin film composite (TFC) membranes. In advanced developments of thin film membranes, an attempt was made to spread a new generation of membranes called thin film nano composite (TFN) membranes. However, in the last generation of TFNs, an ultrathin selective film of nanoparticles is coated...

Enhanced ACS algorithms for plastic analysis of planar frames

In recent years, the trend in solving optimization problems has been directed toward using heuristic algorithms such as neural networks, genetic and ant colony algorithms. The main reason for this trend can be attributed to the fact that these algorithms can be efficiently adjusted to the specific search space to which they are applied and consequently they can be used for many optimization pro...

About Generic Conversions from any Weakly Secure Encryption Scheme into a Chosen-Ciphertext Secure Scheme

Since the appearance of public-key cryptography in the seminal DiffieHellman paper, many schemes have been proposed, but many have been broken. Indeed, for many people, the simple fact that a cryptographic algorithm withstands cryptanalytic attacks for several years is considered as a kind of validation. But some schemes took a long time before being widely studied, and maybe thereafter being b...
