Due to time periodic characteristic of unsteady response induced by blade vibration,using frequency domain harmonic balance computation technique,with structural dynamics analysis,the unsteady flow field around oscillating blades was numerically simulated in one-way fluid-structure coupled manner.The flutter characteristics of blades were predicted

A problem from a class of unsteady plane potential flows with a free boundary is considered.The entire boundary occupied by the liquid is free, and a zero pressure is maintained.There are Cord Winder Assembly neither external nor capillary forces.The motion is driven by inertia.The parameters prescribed at the initial time are the CRYSTAL ANGEL vel

Large-scale multiple-antenna systems with large bandwidth are APP CONTROLLED fundamental for future wireless communications, where the base station employs a large antenna array.In this scenario, one problem faced is the large energy consumption as the number of receive antennas scales up.Recently, low-resolution analog-to-digital converters (ADCs)

Soapstone production in the Gusii region is one of the oldest traditional handcraft industries in Kenya.The history of the industry dates back hundreds and perhaps even thousands of years.Initially made as traditional handcraft for local use over the years, the products have been transformed into tourist items that are sold to both domestic axle pu

A cardinal feature of malignant melanoma is its metastatic propensity.An incomplete view of the genetic events driving metastatic progression has been a major barrier to rational development of effective therapeutics and prognostic diagnostics for melanoma patients.In this study, we conducted global genomic characterization of primary and metastati
