Controlling Electromagnetic Surface Waves with Scalar and Tensor Impedance Surfaces.
(2013)
The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional ...
Energy-efficient Reactive Radio Design in Body Area Networks.
(2013)
A wireless body area network (WBAN) consists of several mobile devices worn on the human body. WBANs have enormous potential in health monitoring systems as it eliminates the inconvenience of having wires around the patient’s ...
Joint collision resolution and transmit‐power adjustment for Aloha‐type random access
(Wiley Subscription Services, Inc., A Wiley Company, 2013-02-10)
We consider uplink random access for which slotted Aloha has usually been employed with unknown channel conditions. Upon failure of a transmission attempt, a user cannot tell whether the failure was caused by collision ...
Substrate response of a floating gate n-channel MOS memory cell subject to a positive linear ramp voltage
(Elsevier, 1981-03)
A computer simulated substrate response of an n-channel MOS floating gate transistor to a positive linear ramping gate voltage was investigated. Device parameters, such as the channel length, effective electron mobility, ...
Amorphous In-Ga-Zn-O Thin-Film Transistors for Next Generation Ultra-High Definition Active-Matrix Liquid Crystal Displays.
(2015)
Next generation ultra-high definition (UHD) active-matrix flat-panel displays have resolutions of 3840x2160 (4K) or 7680x4320 (8K) pixels shown at 120 Hz. The UHD display is expected to bring about immersive viewing ...
Control of Electron and Ion Energy Distributions in Inductively Coupled Plasmas Using Pulsed Power and dc Biases For Fabrication of Microelectronics.
(2014)
In order to meet present and upcoming challenges to reduce feature sizes below 22 nm, advanced plasma etching techniques are required, necessitating tighter control over plasma properties and etch characteristics. Better ...
An extended vascular model for less biased estimation of permeability parameters in DCEâ T1 images
(ErlbaumWiley Periodicals, Inc., 2017-06)
Simultaneous Multislice Functional Magnetic Resonance Imaging.
(2016)
Functional magnetic resonance imaging (fMRI) is a valuable tool for mapping brain activity in many fields. Since functional activity is determined by temporal signal changes, undesired fluctuations from physiological motion ...
An Auxiliary RF Channel with Convenient Phase Control for NMR Spectrometers
(Elsevier, 1993-09)
