An evaluation method for link importance based on the characteristic of network communication

Jiang Yu,Hu Aiqun,He Ming

Strategic Study of CAE 2009, Volume 11, Issue 9,   Pages 64-67

Abstract:

A method for finding the most vital edge based on the characteristic of network communication is proposed. The link importance is determined by its using frequency in all-pairs shortest paths and the most vital edge results in the highest frequency. Without the commonly used edge-deletion and edge-contraction methods, the proposed algorithm directly reflects the edge's contribution to the network communication and the relative importance of the two edges in the network can be evaluated. The algorithm analyses and the experimental results show that this algorithm overcomes the currently existent problems and provides a more reasonable principle for ranking edges which is consistent with our intuitive judgments.

Computation of the protein molecular mechanism using adaptive dihedral angle increments

Mikel DIEZ, Victor PETUYA, Mónica URIZAR, Erik MACHO, Oscar ALTUZARRRA

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 1,   Pages 104-108 doi: 10.1007/s11465-013-0360-9

Abstract:

Protein motion simulation is still a troublesome problem yet to be solved, especially due to its high computational requirements. The procedure presented in this paper makes use of the proteins’ real degrees of freedom (DOFs). The procedure makes no use of any intermediate energy minimization processes that may alter the motion path or result in very high computational cost requirements. In order to reduce the computational cost, presented algorithms make use of the balls and rods approach for protein structure modelization. Also, structures are normalized in order to minimize inaccuracies introduced by experimental methods, providing a more efficient but still accurate structure for motion simulation.
