Filtered Fiction, Tunnel Truth
The purpose of this writing is to ask questions about identity, to re-evaluate and to better articulate my world and self. The form of this manuscript is a blend of poetry and prose forms, mainly autobiographical in nature, somewhat fictionalized (or revised) and using subjects that are most …

Frequency-Filtered Photon Correlations
… approach for measuring and calculating frequency-filtered photon correlations is to filter the source field of interest with a Lorentzian-type filter, e.g., a tunable single-mode cavity or detector atom. However, given the inverse relation between a filter’s bandwidth and temporal response, there …

RIFL : a language with filtered iterators
… handle errors with a new control structure, filtered iterators. A filtered iterator treats inputs as collections of input units, iterates over the units, uses the program itself to filter out unanticipated units, and atomically updates program state for each unit. Filtered iterators can …

Dual Filtered Graphs for Kac-Moody algebras
We construct a strong filtered graph $\Gamma_s(\Lambda)$ dependent on the dominant weight $\Lambda$, and a weak filtered graph $\Gamma_w(\Kcen)$ dependent on the canonical central element $\Kcen$ for an arbitrary Kac-Moody algebra $g$. In our construction, both graphs $(\Gamma_s(\Lambda), …

Nonlinear UAV Flight Control Using Command Filtered Backstepping
… specifically flight path control via command filtered backstepping, for use in AME UAS's Fury® 1500 unmanned flying wing aircraft. Backstepping is a recursive, control-effort minimizing, constructive design procedure that interlaces the choice of a Lyapunov function with the design of feedback …

Ductility demands of filtered earthquakes on reinforced concrete frames
… the destructive nature of seismic waves filtered through soft soils. Key characteristics of filtered ground motions are generally amplified acceleration, increased predominant period, and lengthened duration of strong shaking. Filtering of seismic waves through the soft soils in the …

Unbiased Filtered Rayleigh Scattering Measurement Model for Aerodynamic Flows
The filtered Rayleigh scattering (FRS) optical diagnostic has become an attractive technique for advanced aerodynamic measurements. The appeal of FRS is that it can simultaneously quantify density, temperature, and vector velocity. Additionally, it is entirely non-intrusive to the flow since the …

Filtered Rayleigh Scattering with an Application to Force Component Decomposition
Filtered Rayleigh scattering (FRS) is a laser-based measurement technique that makes use of the scattering of light off particles that are much smaller than the wavelength of light that hits them (i.e., Rayleigh scattering of air molecules). The scattered laser light is altered after encountering …

Multi-Property Internal Flow Field Quantification using Molecular Filtered Rayleigh Scattering
… practical, non-intrusive measurements using filtered Rayleigh scattering (FRS) are presented and analyzed for the multi-property quantification of internal flow fields. Validation is challenging in applying computational fluid dynamics (CFD) solutions to real-world scenarios, necessitating …

A Filtered-Wall Formulation for Large -Eddy Simulation of Wall -Bounded Turbulence
… applied to the Navier-Stokes equations, and the filtered boundaries are accounted for, a boundary term appears in the equations. The boundary term depends on the unfiltered wall stress, which needs to be modeled. Thus two modeling problems need to be addressed for LES of wall-bounded flows in …

Implementing a filtered term structure model in the South African bond market
… government bonds. We review and implement the filtered term structure model proposed by Gombani, Jaschke and Runggaldier that defines an arbitrage free pricing system that is consistent with liquid bond prices. The model is derived in two stages called the underlying and perturbed models. The …

A Filtered Multitone (FMT) Implementation with Custom Instructions on an Altera FPGA
There is a belief that radio frequencies are running out. However, according to a report from the Federal Communications Commission (FCC) in 2002, a different story was told : At any given time and location, much of the prized spectrum lies idle. At the same time, FCC revealed the fact that, in …

Shear and consolidation behavior of slurry-deposited, desiccated tailings and compacted filtered tailings
… and desiccated tailings versus compacted filtered tailings. In general, the evaluation supports the hypothesis that desiccation and resaturation of a hard rock mine tailings yield higher peak undrained shear strengths relative to compacted filtered tailings when considering similar initial …

Application of the Filtered-X LMS Algorithm for Disturbance Rejection in Time-Periodic Systems
… systems in particular until recently. The filtered-X LMS algorithm is regarded as the best disturbance rejection technique for aperiodic systems by many, as has been proven in the acoustics industry for rejecting unwanted noise. Since this is essentially a feedforward approach, we might …
