An active antenna for transmitter application in S frequency band is designed and analyzed using harmonic balance technique which is based on the nonlinear model of active devices. In this active antenna, the amplifier is integrated with the radiator which is a rectangular patch antenna. This patch antenna is analyzed employing full-wave momentum method. By applying nonlinear model of transisto...

The presented work discusses the vibration behavior of an axial turbine, analyzed using finite element method (FEM) commercial software ANSYS®. turbine was modeled as a 2-D plate type structure discretized with 4-noded shell 63 elements to save computational time. Constraints were applied keeping in view actual operating conditions. more than one FE meshes. Mesh sensitivity analysis carried out...

background haemorrhoids are cushions of submucosal vascular tissue located in the anal canal starting just distal to the dentate line. haemorrhoidal disease is a common anorectal disorder which has symptoms of bleeding, prolapse, pain, thrombosis, mucus discharge, and pruritus. haemorrhoidectomy is one of most frequently performed anorectal operation worldwide. objectives the aim of this study ...

This paper explores whether a speaker's voice quality, de®ned as the perceived timbre of someone's speech, changes as a function of variation in speech melody. Analyses are based on several productions of the vowel `a', provided with di€erent intonation patterns. It appears that in general fundamental frequency covaries with the `strength relationship' between the ®rst two harmonics (H1±H2). Th...
