Web search has become an important task for many individuals. As there is rapid growth of the internet, effective searches plays a vital role. Most of us, however, have tough frustration in making an attempt to search for something on the online. Metadata can be used to facilitate the searching of Web contents. We have proposed an algorithm to extract Metadata using ElementTree [EMET], new sear...

|Iterative-deepening searchesmimic a breadthrst node expansion with a series of depthrst searches that operate with successively extended search horizons. They have been proposed as a simple way to reduce the space complexity of bestrst searches like A* from exponential to linear in the search depth. But there is more to iterative-deepening than just a reduction of storage space. As we show, th...

Carrier multiplication describes an interesting optical phenomenon in semiconductors whereby more than one electron-hole pair, or exciton, can be simultaneously generated upon absorption of a single high-energy photon. So far, it has been highly debated whether the carrier multiplication efficiency is enhanced in semiconductor nanocrystals as compared with their bulk counterpart. The controvers...

A bioinspired cocoon-like anticancer drug delivery system consisting of a deoxyribonuclease (DNase)-degradable DNA nanoclew (NCl) embedded with an acid-responsive DNase I nanocapsule (NCa) was developed for targeted cancer treatment. The NCl was assembled from a long-chain single-stranded DNA synthesized by rolling-circle amplification (RCA). Multiple GC-pair sequences were integrated into the ...

We study the equilibrium thermodynamics between two ternary ionic systems in immiscible solvents characterized by different dielectric constants. We consider system geometries wherein the two phases of immiscible solvents occupy, respectively, semi-infinite regions of space separated by neutral and charged planar interfaces. Specifically we analyze the case where the ternary system is composed ...

Previously, motivation for enhanced b → sg from new flavor physics has centered on discrepancies between theory and experiment. Here two experimental hints are considered: (1) updated measurements of the charm multiplicity and B(B → Xcc̄s) at the Υ(4S) imply B(B → Xno charm) ≈ 12.4 ± 5.6%, (2) the B → KX and B → K+/K−X branching fractions are in excess of conventional B → Xc → KX yields by about...

In this paper, detection and assessment of structural damage using the changes in a structure's natural frequencies is addressed as an optimization problem. The damaged element(s) and the percentage of damage are considered as the problem variables. The objective is to set these variables such that the natural frequencies of the model correspond to the experimentally measured frequencies of the...

Changes in dynamic properties of structures indicate occurrence of damages in the structures. In this paper, a new two stage algorithm for damage detection of large structure is introduced. A modified Residual Force Method is utilized to locate the damage regions in structures, especially barrel vaults, and then the enhanced Charged System Search (CSS) Algorithm is used to quantify the amount o...

The barrel vaults are composed of member elements arranged on a cylindrical surface. This kind of structure is utilized to cover the long spans. In this paper, the hybrid charge system search and particle swarm optimization algorithm is improved and utilized to optimal design of single-layer barrel vault frames. Some modifications on parameter values are performed to enhance the performance of ...
