Bed surface particle size patchiness may play a central role in bedload and morphologic response to changes in sediment supply in gravel-bed rivers. Here we test a 1-D model (from Parker ebook) of bedload transport, surface grain size, and channel profile with two previously published flume studies that documented bed surface response, and specifically patch development, to reduced sediment sup...

In this paper, we present coarse-grain and fine-grain diagnosis techniques to identify a faulty element in FPGA interconnects. The fault model we use is stuck-open and resistive-open for interconnects. The presented technique requires only a small number of configurations while offering high resolution diagnosis. We implemented this technique on real FPGA chips and verified it using fault emula...

[1] The beds of steep streams are typically composed of relatively immobile boulders and more mobile patches of gravel and cobbles. Little is known about how variability in flow and sediment flux affect the area, thickness, composition, and grain mobility of sediment patches. To better understand patch dynamics, we measured flow, sediment transport, and bed properties in two steep channels. Pat...

Fine grain (1–2 lm) 2%, 3% KNbO3-BaTiO3 ceramics have been synthesized via the solid state reaction method. Fine and coarse grain ceramics sintered at different temperatures exhibit peaks in dielectric constant and internal friction in the vicinity of transition temperatures. Doping lowered the Curie point and raised the temperatures for the structural transformations between orthorhombic and r...

ii Also, an extensive state-of-the-art survey of the reconfigurable IP blocks is presented. Both main reconfigurable categories, i.e. fine grain and coarse grain, are covered and the most remarkable prevailing implementations are introduced extensively. Each of the architectures is categorized according to the computational granularity, communication topology and source of block, i.e., academic...

The paper addresses a broad readership in information technology, computer science and related areas, and gives an introduction to fine grain and coarse grain morphware, reconfigurable computing, and its impact on classical computer science and business models. It points out trends driven by microelectronics technology, EDA, and the mind set of datastream-based computing. 2003 Elsevier B.V. All...

Abstract: Equal channel angular extrusion (ECAE) is a promising technique for production of ultra fine-grain (UFG) materials of few hundred nanometers size. In this research, the grain refinement of aluminium strip is accelerated by sandwiching it between two copper strips and then subjecting the three strips to ECAE process simultaneously. The loosely packed copper-aluminium-copper laminated b...

The virtualization of resources in SMP machines with Xen offers automatic round-robin based coarse-grain assignment of VMs to physical processors and manual assignment via privileged commands. However, two problems can arise in Grid environments: (1) if Xen’s sEDF scheduler assigns the VMs, then some processors could be over or underutilized and the VMs could receive more resources than specifi...

Data driven architecture has been widely proposed in literature as an alternative to the von-Neumann design to handle real time and fifth generation applications. ,2 However, the network delays at the fine-grain dataflow level and handling of large arrays are some of the problems which should be addressed in these architectures. In this paper, we introduce a new model for dataflow computation w...
