In a previous paper [I. Bena, M. Malek Mansour, and F. Baras, Phys. Rev. E 59, 5503 (1999)] the statistical properties of linearized Kolmogorov flow were studied, using the formalism of fluctuating hydrodynamics. In this paper the nonlinear regime is considered, with emphasis on the statistical properties of the flow near the first instability. The normal form amplitude equation is derived for ...

Cluster-based and iSCSI-based storage systems rely on standard TCP/IP-over-Ethernet for client access to data. Unfortunately, when data is striped over multiple networked storage nodes, a client can experience a TCP throughput collapse that results in much lower read bandwidth than should be provided by the available network links. Conceptually, this problem arises because the client simultaneo...

in early islamic era, architecture in khorasan was followed the common features of early islamic architecture style; such as simplicity in construction and ornament. in the later periods, especially in seljuq dynasty, the application of brick, stucco, tiling and inscription had been used more in architectural ornament. then, in the short period under the khwarizmshahid dynasty in khorasan, two-...

The growing demand for nickel metal and the depletion of high-grade sulfide ore reserves have turned direction industry towards laterites which are not desirable as primary source due to their low Ni content more energy-intensive processing. Thus, alternative routes essential effectively processing these ores while reducing costs greenhouse gas emissions. Solid-state reduction followed by magne...

S. Jamshid Mousavi (corresponding author) M. Shourian Department of Civil Engineering, Amirkabir University of Technology (Tehran Polytechnic), Tehran, Iran E-mail: [email protected] A mixed integer optimization model is formulated for capacity optimization of a hydropower storage project with control on reliability of meeting the project’s firm energy yield. Particle swarm optimization (PSO) i...

Schlieren imaging in wind-tunnels is extensively utilized to study the effects of air on an airplane surface. One of the interesting subjects for research is to study the effects of speed change on the airplane surface. Speed change results in occurrence of shock waves, which are visualized as lines on Schlieren images. In this paper, we study the problem of detecting speed of a plane after occ...

INTRODUCTION Primordial germ cells have an extra-gonadic origin in the chick embryo. They may be found in the primitive streak or head-process stage, in an area known as the germinal crescent, located in the endoderm anterior and antero-lateral to the primitive streak at the junction of the area opaca and area pellucida (Swift, 1914; Willier, 1937; Reynaud, 1967; Clawson & Domm, 1969). Primordi...
