In this paper, we present an algorithm which combines the pin assignment step and the global routing step in the physical design of VLSI circuits. Our algorithm is based on two key theorems: the channel pin assignment theorem and the block boundary decomposition theorem. These two theorems enable us to deal successfully with the high complexity resulting from combining the pin assignment and gl...

Abstract—The wear measuring and wear modelling are fundamental issues in the industrial field, mainly correlated to the economy and safety. Therefore, there is a need to study the wear measurements and wear estimation. Pin-on-disc test is the most common test which is used to study the wear behaviour. In this paper, the pin-on-disc (AEROTECH UNIDEX 11) is used for the investigation of the effec...

Puroindoline (Pina and Pinb) genes control grain texture or hardness in wheat. Wild-type/soft alleles lead to softer grain while a mutation in one or both of these genes results in a hard grain. Variation in hardness in genotypes with identical Pin alleles (wild-type or mutant) is known but the molecular basis of this is not known. We now report the identification of wheat genotypes with hard g...

Pin-1 has been shown to regulate several phases of the cell cycle and is strikingly overexpressed in many human cancers. Vascular endothelial growth factor (VEGF)-C is a potent lymphangiogenic factor produced by tumor and stromal cells. However, little is known about the roles of Pin-1 and VEGF-C in breast carcinoma. p53 protein and cyclin D1 overexpressions have been shown to play a role as pr...

Since the 80’s, industrial core calculations employ two-step scheme based on prior cross sections preparation with few energy groups and in homogenized reference geometries. Spatial homogenization fuel assembly quarters is most frequent calculation option nowadays, relying efficient nodal solvers using a coarse mesh. Pin-wise reaction rates are then reconstructed by dehomogenization techniques....

in this study, behavior of pin-loaded glass fiber reinforced with polyethylene laminated composites with different stacking sequence and different dimensions has been observed experimentally and stress analysis was performed using ansys software. the aim is to investigate stresses, failure strength and failure mode of composite laminates containing a pin loaded hole when the material exhibits l...
