A HIGH RESOLUTION DATA-ADAPTIVE TIME-FREQUENCY REPRESENTATION
(1987)The short-time Fourier transform and the Wigner distribution are the time-frequency representations that have received the most attention. The Wigner distribution has a number of desirable properties, but it introduces ... -
A hybrid relaying protocol for the parallel-relay network
(2010)Cooperation among radios in wireless networks has been shown to improve communication in several aspects. We analyze a wireless network which employs multiple parallel relay transceivers to assist in communication between ... -
A Linear Transform Scheme for Combining Weights into Scores
(1998-10-09)Ranking has been widely used in many applications. A ranking scheme usually employs a "scoring rule" that assigns a final numerical value to each and every object to be ranked. A scoring rule normally involves the use of ... -
A longitudinal cohort study of malaria exposure and changing serostatus in a malaria endemic area of rural Tanzania
(2017-08-02)Abstract Background Measurements of anti-malarial antibodies are increasingly used as a proxy of transmission intensity. Most serological surveys are based on the use of ... -
A MAC protocol for Multi Frequency Physical Layer
(2003-01-23)Existing MAC protocols for wireless LAN systems assume that a particular node can operate on only one frequency and that most/all of the nodes operate on the same frequency. We propose a MAC protocol for use in an ad hoc ... -
A Matter of Perspective: Reliable Communication and Coping with Interference with Only Local Views
(2012-09-05)This dissertation studies interference in wireless networks. Interference results from multiple simultaneous attempts to communicate, often between unassociated sources and receivers, preventing extensive coordination. ... -
A maximum pseudo-likelihood approach for phylogenetic networks
(2015)Abstract Background Several phylogenomic analyses have recently demonstrated the need to account simultaneously for incomplete lineage sorting (ILS) and hybridization when ... -
A Miniaturized QEPAS Trace Gas Sensor with a 3D-Printed Acoustic Detection Module
(2017)A 3D printing technique was introduced to a quartz-enhanced photoacoustic spectroscopy (QEPAS) sensor and is reported for the first time. The acoustic detection module (ADM) was designed and fabricated using the 3D printing ... -
A minimum-cost-neighbor multicast routing protocol for mobile wireless ad hoc networks
(2010)MiCoN (Minimum-Cost Neighbor) is a new on-demand multicast routing protocol for mobile wireless ad hoc networks. Multicast routing in MiCoN is based on a new multi-route unicast routing protocol for maintaining routes ... -
A model of sarcolemmal calcium(2+) currents and cytosolic calcium(2+) transients in a rat ventricular cell
(2000)We have developed a mathematical model of the L-type Ca2+ current and cytosolic Ca2+ transient, which is based on data from whole-cell voltage clamp experiments on rat ventricular myocytes. Modified Goldman-Hodgkin-Katz ... -
A New Approach to Routing With Dynamic Metrics
(1998-11-18)We present a new routing algorithm to compute paths within a network using dynamic link metrics. Dynamic link metrics are cost metrics that depend on a link's dynamic characteristics, e.g., the congestion on the link. Our ... -
A NOVEL FRAMEWORK FOR SURFACE RECONSTRUCTION FROM 3-DIMENSIONAL CONTOURS
(1986)In many applications, such as computer vision, medical imaging, scene forming, and motion animation, surface data is available in the form of two-dimensional (2D) or three-dimensional (3D) contours. Reconstruction of the ... -
A performance study of deployment factors in wireless mesh networks
(2007)This thesis presents a measurement-parameterized performance study of deployment factors in wireless mesh networks using four performance metrics: client coverage area, backhaul tier connectivity, protocol-dependent ... -
A perspective on climate model hierarchies
(2017)To understand Earth's climate, climate modelers employ a hierarchy of climate models spanning a wide spectrum of complexity and comprehensiveness. This essay, inspired by the World Climate Research Programme's recent “Model ...
