knowledge of resistance to airflow through agricultural products is an important consideration in the design of drying, cooling, or aeration systems and proper fan selection for these systems. resistance to airflow of bulk chickpea seeds was studied at moisture contents in the range of 9.21 to 21.36 % (wet basis) for airflow rate range from 0.02 to 0.50 m3 s-1 m-2, using an experimental test co...
• First report on the reactive sputter deposition and post-deposition heat treatment of Mn 3 Ag (1- x ) Cu ( N thin films for ultra-low TCR application. Increasing doping concentration in controls stabilization manganese oxide upper surface layer. The extent oxidation crystallization underlying film are competing events to fine tune electrical properties. Optimising temperature results values b...
Random coe cient regression models have been applied in di erent elds and they constitute a unifying setup for many statistical problems. The nonparametric study of this model started with Beran and Hall (1992) and it has become a fruitful framework. In this paper we propose and study statistics for testing a basic hypothesis concerning this model: the constancy of coe cients. The asymptotic be...
Research on the Flow Resistance Coefficient of a Multihole, Secondary Pressure-Reducing Sleeve Valve
Obtaining device parameters of thermal microsensors is essential for evaluating their performances and simulation modeling. We report an ac electrical method for extracting these parameters experimentally with relatively simple instrumentation. The basic parameters of resistive microsensors, the resistance, temperature coefficient of resistance, thermal capacitance, and conductance, are derivab...
