This article examines encounters with darkness through compositions of houselights and their elimination, arguing that not all brushes are alike. While eradicating directs seeing focuses attention, which already implies a dramaturgical-compositional significance, the design light in auditorium is predominantly relegated to preshow preamble will quickly be switched off. In response, I propose pl...

Four tool plunging paths including a one-time path and three step-by-step were designed to study the effects of on welded joint properties pinless friction stir spot welding (PFSSW). The appearance, cross-sectional microstructure, temperature, microhardness, tensile shear failure load PFSSW thin copper sheets under different explored. Furthermore, fracture modes joints analyzed. Studies showed ...

12.7-mm thick plates of 6061-T6511 aluminum alloy and high hardness steel (528 HV) were successfully joined by a friction stir bonding process using a tungsten Process parameter variation experiments, which geometry, plunge and traverse rates, tool offset, spindle tilt, and rotation speed, were conducted to develop a parameter set which yielded a defect free joint. Laboratory tensile tests exhi...

A model of an economy with random matching and monetary exchanges is shown to have two equilibrium regimes. In the first, agents find an opportunity for a sale in each period and there is full-employment. In the second, agents attempt to increase their balances because of a lack of opportunities for sales which is in turn induced by the saving for higher money balances, and there is unemploymen...
