Vestibular Findings in Military Band Musicians
Introduction Exposure to music is the subject of many studies because it is related to an individual's professional and social activities. Objectives Evaluate the vestibular behavior in military band musicians. Methods A retrospective cross-sectional study was performed. Nineteen musicians with ages ranging from 21 to 46 years were evaluated (average = 33.7 years and standard deviation = 7.2 ye...
متن کاملBand-Notched Ultra-Wideband Antenna with Asymmetric Coupled-Line for WLAN and X-Band Military Satellite
This paper presents a novel ultra-wideband (UWB) antenna that rejects narrow and broad bands and is suitable for wireless communications. The base of the proposed antenna has a circular patch that can cover the UWB frequency range (3.1~10.6 GHz). The interference issues caused by co-existence within the UWB operation frequency are overcome by a design that uses a parallel-coupled asymmetric dua...
متن کاملMIMO capacities for different antenna arrangements based on double directional wide-band channel measurements
The performance of future wireless communication systems can be highly increased by utilizing multiple antennas at both sides of a wireless communication link. A concept for MIMO double directional wide-band channel measurements is presented and high-resolution channel parameter estimation is applied. Furthermore, a procedure, where MIMO capacities are obtained by one single SISO channel transf...
متن کاملModified U-Slot Stacked Micro-Strip Patch Antenna for Ultra-Wideband Applications in S Band, C Band and X Band
The U-slot micro-strip patch antennas were originally developed for bandwidth broadening applications. This study presents a transmission line feed to modify the U-slot stacked rectangular micro-strip patch antenna for Ultra-Wide Band (UWB) communications. The modified antenna has a U-cut loaded with parallel slits and corner slots and is printed on a dielectric substrate of FR4 with relative p...
متن کاملNonresonance Conditions for Arrangements
We prove a vanishing theorem for the cohomology of the complement of a complex hyperplane arrangement with coefficients in a complex local system. This result is compared with other vanishing theorems, and used to study Milnor fibers of line arrangements, and hypersurface arrangements.
