The purpose of this study is to investigate a small centrifugal cooling fan applied on notebook computers, which is consisted of a forward-curved impeller and a centrifugal housing. First of all, a basic rotor impeller is designed with the cascade theory. To manufacture the mock-up for experimental verification, the design fan will be expressed in the CAD/CAM format for the CNC machine. All exp...

Accurate methods of reconstructing historical tree diameters from increment cores are important because diameter is used in allometric equations to predict stand characteristics and to study stand dynamics. The conventional reconstruction method assumes that the pith is in the centre of the stem. This is often incorrect, as evidenced by a pith increment index quantifying the deviation between t...

A field experiment was executed under sub-tropical conditions during the period from April 2020 to March 2021 observe effects of bulb sizes on flower and yield tuberose cv. single. The consisted three namely, a small-sized (1.0-1.5 cm in diameter); medium-sized (1.6-2.5 diameter) large sized (2.6-3.0 diameter). Results disclosed that plant height, number leaves plant-1, leaf length breadth, lat...

We give an optimal wait free implementation of an increment register An increment register is a concurrent object consisting of an integer valued register with an increment operation that atomically increments the register and returns the previous value We implement this register in a synchronous message passing model with crash failures In our implementation an increment operation halts in O l...
