Discovering Administrative Encouragement Within Turnaround Principals’ Leadership
… performance; however, turnaround principals (TAPs) have been considered hallmarks of school turnaround. While the key practices for TAPs to navigate school improvement are known, little is known about how TAPs shepherd the humanistic aspects of change for school improvement. This qualitative …

Design of a model pipeline for testing of piezoelectric micro power generator for the Trans-Alaska Pipeline System
… system for the Trans-Alaska Pipeline System (TAPS), a distributed wireless self-powered sensor array is needed to monitor the entire length of the pipeline at all times. Such a sensor faces two primary challenges: a method to provide power for the sensor, and a method to detect corrosion. This …

Synthesis of polyionic tetraazaporphyrins and their Langmuir-Blodgett properties.
Octaalkylthio tetraazaporphyrins (TAPS) having carboxylic acid moieties attached via alkyl spacers have been prepared as new polyionic discotics. Octaester TAP precursors were synthesized following the established Mg propanolate route and subsequently cleaved to the octaacid TAPs. Octaacid TAPs …

Investigation of phosphines as potential host materials in blue dye-doped organic light emitting devices
… suggested that tertiary aromatic diphosphines (TAPs) may be suitable candidates. Therefore, the P-containing materials, 4,4'-bis(naphthylphenylphosphino)biphenyl (alpha-P-NPD) and 4,4'-bis(diphenylphosphino)biphenyl (P-DDB) were synthesized and the photophysical properties were evaluated and …

Modeling and mapping of MaeLa refugee camp water supply
… second scenario was to increase the flow rate at taps of low supply; the third scenario aimed at adding taps to parts of the camp without easy access to running water. The first scenario consisted in opening valves to connect subsystems: it increased the flow rate at taps of large supply more so …

Fatigue design of oil tankers: a design approach
… operate on the Trans-Alaska Pipeline Service (TAPS) route have exhibited a large number of structural fatigue cracks. These cracks can be attributed to the increase in use of high strength steel in tanker construction and to the harsh operating environment in the Gulf of Alaska. In response to …

SURPRISE-INDUCED DEAFNESS -- TEMPORAL CHARACTERISTICS OF A STIMULUS-DRIVEN LIMITATION IN AUDITORY SELECTIVE ATTENTION
… was directly compared to the paradigm which taps onto goal-directed limitation – i.e., auditory attentional blink or AAB. The result suggested that SiD indeed taps onto the stimulus-driven limitation in auditory selective attention.

Density relaxation of granular matter through Monte Carlo and granular dynamics simulations
… as a result of the application of discrete taps or continuous vibrations. In this dissertation, the density relaxation phenomenon is promoted by the application of discrete taps to a periodic system of monodisperse spheres. Both stochastic ( Monte Carlo) and deterministic (granular dynamics) …

ATM over an asymmetric digital subscriber line
… effects of different impairments such as bridge taps, line length, and wire gauge are also considered. The impairments in the copper loop are investigated to highlight the effect they have on the frequency response of the line. The line length and gauge increase the attenuation while bride taps …

Throughput and coverage improvement in wireless mesh networks
… network, nodes known as transit access points (TAPs) cooperatively forward traffic from users that may be multiple wireless hops apart. A limited number of TAPs also have a connection directly to the Internet, serving as gateway nodes that provide Internet connectivity to the entire mesh …

Magnetic force microscopy studies of mesoscopic superconducting structures
… thermally activated phase slips (TAPS). The SR model allows us to experimentally determine the rate of TAPS and compare it to the Langer-Ambegaokar-McCumber-Halperin (LAMH) theory for TAPS in 1D superconducting structures. Further, we use the SR model to qualitatively study the …

An experimental determination of the trailing-edge base pressure on blades in transonic turbine cascades
… this large-scale blade, five static pressure taps were placed around the trailing edge. In addition to these taps, the rearward portion of the suction surface was also instrumented with five static pressure taps. The aerodynamic losses were quantified by a loss coefficient: the mass-averaged …

Design and fabrication of a tapped densification apparatus for bulk solids
… is subjected to a long sequence of discrete taps, after which the bulk density - the total mass divided by the volume occupied -- is determined. Current technology exists to achieve the maximum tap density by subjecting a container to a user defined number of taps at a specific, predetermined …

Voltage Security Optimization for Power Transmission Systems
… set-points for switching shunts, transformer taps, and voltage magnitudes at the regulated buses. The primary goal is to maximize the dynamic reactive power reserve of the system, by minimizing the reactive power supplied by synchronous generators. The secondary goal is to minimize changes in …

Wide band TX Leakage Cancellation for FDD Transceivers
… of several cancellation paths (also known as taps). In each of the taps, there is an attenuator, phase shifter and delay line. These components are utilized to recondition the reference signal which is the replica of the output signal of the high power amplifier (PA) in the TX path. The output …

Stereophonic Acoustic Echo Cancellation: Theory and Implementation
… structures may need to model a few non-causal taps even if the fullband impulse response is causal. This phenomenon is analyzed in Paper III. Formulas to calculate the number of non-causal taps needed are also presented in the paper. The fundamental problem in stereophonic acoustic echo …
