Dynamic processes of interacting units on a network are out equilibrium in general. In the case directed tree, dynamic cavity method provides an efficient tool that characterises trajectory process for linear threshold model. However, because computational complexity method, analysis has been limited to systems where largest number neighbours is small. We devise implementation which substantial...
Despite recent advances in face recognition systems, they suffer from serious problems because of the extensive types of changes in human face (changes like light, glasses, head tilt, different emotional modes). Each one of these factors can significantly reduce the face recognition accuracy. Several methods have been proposed by researchers to overcome these problems. Nonetheless, in recent ye...
To investigate land use changes, Qale Shahrokh basin (15098.1 ha area) was selected. Satellite images of Landsat sensors (MSS, TM and ETM+) were used. After improvement and different enhancement analysis of images such as FCC, PCA, the study area was checked using GPS and topographic maps (1:50000) and other information. Land use units were determined using classified random sampling method. Ma...
Spatial coupling has been successfully applied to various problems, ranging from error correcting codes to compressive sensing, and shown to have outstanding performance under message-passing algorithms. In particular, spatially coupled low-density parity-check (LDPC) codes were proven to universally achieve capacity under belief-propagation (BP) decoding. In this research proposal, we describe...
