Conformai wearable monopole antenna backed by a compact EBG structure for body area networks
(Institute of Electrical and Electronics Engineers Inc., 2017)A compact planar monopole antenna backed by an electromagnetic bandgap (EBG) structure is presented. The antenna is conformal to the human body and is intended for wearable applications in wireless body area networks. It ...

A congestion control algorithm for max-min resource allocation and bounded queue sizes
(2004)This paper deals with the congestion control problem in computer networks which is viewed as a resource allocation problem constrained by the additional requirement that the queue sizes need to be bounded. We propose a ...

Congestion control for differentiated-services using non-linear control theory
(2001)The growing demand of computer usage requires efficient ways of managing network traffic in order to avoid or at least limit the level of congestion in cases where increases in bandwidth are not desirable or possible. Using ...

A CPS leaky-wave antenna with reduced beam squinting using NRI-TL metamaterials
(2008)A reduced beam-squinting printed leaky-wave antenna (LWA) is proposed, comprising cascaded negative-refractive-index transmission-line (NRI-TL) metamaterial unit cells. Each NRI-TL unit cell is implemented in co-planar ...

Detuning detection in induction motors
(2004)In this article we present a model-based scheme to detect detuned indirect field oriented controllers in current fed induction motors. The detection scheme is based on differential geometric techniques. Numerical simulations ...

Direct quadrature phase shift keying modulation using compact wideband six-port networks
(2012)In this study, the operation of a compact six-port network operating as a quadrature phase shift keying (QPSK) modulator with a wide operational bandwidth is presented. The modulation has been accomplished using two types ...

Distributed finite-time calculation of node eccentricities, graph radius and graph diameter
(2016)The distributed calculation of node eccentricities, graph radius and graph diameter are fundamental steps to tune network protocols (e.g., setting an adequate time-to-live of packets), to select cluster heads, or to execute ...

Distribution theory for the studentized mean for long, short, and negative memory time series
(2013)We consider the problem of estimating the variance of the partial sums of a stationary time series that has either long memory, short memory, negative/intermediate memory, or is the first-difference of such a process. The ...

Dynamic bandwidth allocation in broadband-ISDN using a multileveloptimal control approach
(1995)This paper presents a novel scheme for the dynamic allocation of bandwidth at the virtual path level in B-ISDNs. A fluid flow model is developed to describe the time varying mean behaviour of a virtual path and serves as ...

Effects of Ge concentration, boron co-doping, and hydrogenation on fiber bragg grating characteristics
(2005)In this paper, we compare photosensitivity, refractive-index modulation depth, spectral bandwidth, and excess loss through the inscription of fiber Bragg gratings in unloaded and hydrogen-loaded fibers with low- or ...

Gain Enhancement of Wideband Metamaterial-Loaded Loop Antenna with Tightly Coupled Arc-Shaped Directors
(2017)A wideband and unidirectional loop antenna with enhanced and stable gain is presented. To reduce the size of the antenna, the loop is loaded with three mu-negative (MNG) metamaterial unit-cells. The proposed unit-cells ...

Higher-order accurate polyspectral estimation with flat-top lag-windows
(2009)Improved performance in higher-order spectral density estimation is achieved using a general class of infinite-order kernels. These estimates are asymptotically less biased but with the same order of variance as compared ...

Identification and high bandwidth control of hard disk drive servo systems based on sampled data measurements
(2007)One of the key factors that determines the track density of a hard disk drive (HDD) is the performance characteristics of the HDD servo system, the control system that positions the READ/WRITE magnetic head close to the ...

Information hovering: A new approach for performance acceleration of wireless push systems
(2011)Wireless data broadcasting systems are typically assigned limited operational bandwidth due to their usually wide spatial coverage. This limitation raises issues of increased client waiting times, especially as the total ...

Integrated control of connection admission, flow rate, and bandwidth for ATM based networks
(1996)We consider the combined control problem of connection admission, flow rate, and bandwidth allocation (capacity, service-rate) under nonstationary conditions. A fluid flow model in state variable form describes the time ...
