First Passage Processes in Queuing System MX/GR/1 With Service Delay Discipline
(1994-11-03)This article deals with a general single-server bulk queueing system with a server waiting until the queue will reach level r before it starts processing customers. If at least r customers are available the server takes a ... -
First results on terrestrial gamma ray flashes from the Fermi Gamma-ray Burst Monitor
(2010-07-30)The Gamma-ray Burst Monitor (GBM) on the Fermi Gamma-ray Space Telescope detected 12 intense terrestrial gamma ray flashes (TGFs) during its first year of observation. Typical maximum energies for most of the TGFs are ∼30 ... -
First Steps in Retrofitting a Versatile Software Testing Infrastructure to Android
(2018-12)Are existing software testing technologies satisfying the needs of mobile software testing practitioners? This dissertation provides evidence that the existing technologies fall short of practitioner’s actual needs and ... -
First THz and IR characterization of nanometer-scaled antenna-coupled InGaAs/InP Schottky-diode detectors for room temperature infrared imaging
(2007-05-14)Nanometer high performance InP Schottky detectors are scaled to IR wavelengths. The increased cutoff frequency of the Schottky detector was accomplished by both reducing its capacitance to attofarad range and also by ... -
A First-Principle Power and Energy Model for eVTOL Vehicles
(2019-05)A number of well-established aircraft manufacturers, such as Airbus, Boeing, or Bell, along with new startups have begun developing flying prototypes of electric Vertical Takeoff and Landing vehicles (eVTOL). To certify ... -
Fish Book
The purpose of Fish Book is to test the application of Shape Matching with Shape Contexts to the identification of different fish species. -
Five theories of reasoning: Interconnections and applications to mathematics
(2011)The last century has seen many disciplines place a greater prior-ity on understanding how people reason in a particular domain, and several illuminating theories of informal logic and argumentation have been devel-oped. ... -
Fixed point theorems for convex-power condensing operators relative to the weak topology and applications to volterra integral equations
(2012-06-22)In this paper we present new fixed point theorems for weakly sequentially continuous mappings which are convex-power condensing relative to a measure of weak noncompactness. Our fixed point results extend and improve several ... -
Fixed point theorems for ws-compact mappings in Banach spaces
(2010-11-24)We present new fixed point theorems for ws-compact operators. Our fixed point results are obtained under Sadovskii, Leray-Schauder, Rothe, Altman, Petryshyn, and Furi-Pera type conditions. An example is given to show the ... -
Fixed point theory for admissible type maps with applications
(2009-07-20)We present new Leray-Schauder alternatives, Krasnoselskii and Lefschetz fixed point theory for multivalued maps between Fréchet spaces. As an application we show that our results are directly applicable to establish the ... -
Fixed point theory for Mönch-type maps defined on closed subsets of Fréchet spaces: the projective limit approach
(2005)New Leray-Schauder alternatives are presented for Mönch-type maps defined between Fréchet spaces. The proof relies on viewing a Fréchet space as the projective limit of a sequence of Banach spaces. -
Flagellation Testing of Composite Finger Skirts for Surface Effect Ship (SES) Application
(2021-05)The objective of this research is to create flagellation data for SES finger skirts. The SES design allows it to have a high tonnage with low draft, little drag, low wavemaking resistance, remarkable carrying capacity, and ... -
Flame Synthesis of Iron Oxide Nanowires for Direct Coal Chemical Looping Combustion, and Tungsten Oxide Nanowires for Enhanced Photoelectrochemical Water Splitting.
(2011)The applications of metal oxide NWs are limited because conventional synthesis methods cannot achieve the scalable, rapid, controllable and economical synthesis of high-quality metal oxide NWs. In the present work, two ... -
A flare in the jet of pictor A
(2010-04-13)A Chandra X-ray imaging observation of the jet in Pictor A showed a feature that appears to be a flare that faded between 2000 and 2002. The feature was not detected in a follow-up observation in 2009. The jet itself is ... -
Flexible slosh diaphragm modeling and simulation in propellant tanks
(2014-05)Liquid sloshing and propellant distribution is an important field of research for aerospace applications such as launch vehicles and spacecraft. The propellant mass behavior can greatly influence vehicle dynamics, altering ... -
Flight Path Control During Hypersonic Atmospheric Entry Using Active Magnetic Arrays
(2020-05)The purpose of this thesis is to study the reaction to the Lorentz force induced during the hypersonic regime of flight by an active magnetic field. The effect that a magnetic array has on the flight characteristics of ... -
