On Friday, 14 April 2017, a heavy flash flood occurred in North-West of Iran that affected 12 cities; the most severely affected and damaged ones were Ajabshir and Azarshahr in East Azerbaijan Province. These Flash floods claimed the lives of 42 people. Major casualties occurred when the victims were trapped inside their cars. According to preliminary analyses, flood damages in East Azerbaijan ...

In class, we approached critical phenomena from the view point of correlation functions and discussed renormalization group methods for obtaining values of critical exponents. Here I discuss a parallel idea that studies critical phenomena from properties of random curves which form the domain walls of the critical system. It will be shown that such random curves obey a stochastic differential e...

A concept for solving the communication problem among modules dynamically placed on a reconfigurable device is presented. Based on a dynamic network-on-chip (DyNoC) communication infrastructure, components placed at run-time on a device can mutually communicate. A 4x4 dynamic network-on-chip communication infrastructure prototype, implemented in an FPGA occupies only 7% of the device area and c...

Industrial demands for more compact heat exchangers are a motivation to find new technology features. Electrohydrodynamics (EHD) is introduced as a promising phenomenon for heat transfer enhancement mechanisms. Similar to any new technology, EHD has not been understood completely yet and requires more fundamental studies. In boiling phase change phenomena, nucleation is the dominant mechanism i...

A numerical study is carried out to investigate the laminar forced convection heat transfer from a circular cylinder. The fluid is assumed to be incompressible, the Reynolds number ranged from 0.1 to 1000, and the Prandtl number was equal to 0.7. The range of study includes heat transfer in creeping flow (Re40). The equations were discretized by a control-volume-based finite difference techniqu...

Knowledge of the interactions involving charged, polar and polarizable groups in proteins is fundamental, not only because they are important determinants for gaining insight into biophysical molecular recognition and assembly processes, but also for understanding how the matrix of a protein can be viewed as an electric field capable of inducing Stark perturbations on the spectral properties of...
