A study is made of the behavior of cracks approaching interfaces in all-ceramic crown-like bilayers. Flat specimens are fabricated by fusing porcelain veneers onto Y-TZP and alumina core ceramic plates, with veneer/core matching to minimize residual
The efficiency of optical tweezer manufacturing depends on the number of trapping beams available. Micro optics technology offers the opportunity to significantly increase the number of trapping beams without a significant increase of the cost or size of
Application of a shear field to a concentrated emulsion induces a complex spatial and temporal response. The behavior of a concentrated system is treated as an extrapolation of the well-understood behavior of isolated droplets (or of the behavior of two
The impact-echo method is a technique for flaw detection in concrete. It is based on monitoring the surface motion resulting from a short-duration mechanical impact. The method overcomes many of the barriers associated with flaw detection in concrete based

This paper presents the results of a study aimed at quantifying the performance of water heaters insulated with polyurethane foams using three different blowing agents - HCFC-141b, H2O/CO2, and HFC-245fa. The thermal conductivity of the foam was measured
Translational flux-energy distributions of positive and negative ions have been measured at high electric field-to-gas density ratios (E/N) up to 40 x 10 -18 V m 2 (40 kTd) in diffuse, parallel-plate Townsend discharges in oxygen using an ion energy
Planar laser-induced fluorescence (PLIF) measurements were made to determine two-dimensional spatial maps of CF 2 density as an indicator of chemical uniformity in 92% CF 4/O 2 and 50% C 2F 6/O 2 chamber-cleansing plasmas at pressures between 13.3 Pa (100
Two novel acoustic resonators have been developed, one for measuring the viscosity and a second for measuring the Prandtl number of gases. For viscosity measurements, we use a double Helmholtz resonator called the Greenspan viscometer. The Greenspan

The synthesis, structure, and temperature dependent thermal and electrical properties of off-stoichiometric polycrystalline modified zinc blende quaternary chalcogenides Cu1.33+xZn1.33-xIn1.33Se4, where x = 0, 0.1, 0.2 and 0.3, are investigated
Quantum mechanics allows measurements that surpass the fundamental sensitivity limits of classical methods. To benefit from the quantum advantage in a practical setting, the receiver should use communication channel resources optimally; this can be done
In this work we describe how to efficiently and reliably calculate $p$-$x$ and $T$-$x$ diagrams for binary mixtures of fluids. The method is based on the use of the Helmholtz energy density as the fundamental thermodynamic potential. Through the use of
Preceding chapters have described the near field scanning microwave microscope (NSMM), while discussing both the underlying theory of operation and practical considerations for instrumentation. A primary application area for NSMMs and related microscopes

We characterize the effects of asymmetries, dynamics, and failures when introduced into a cloud computing simulator, which had previously been characterized under static, homogeneous configurations with various patterns of demand and supply. We aim to

The Pan-STARRS1 survey is collecting multi-epoch, multi-color observations of the sky north of declination −30 to unprecedented depths. These data are being photometrically and astrometrically calibrated and will serve as a reference for many other

We present theoretical predictions and experimental measurements for the achievable phase noise, timing jitter, and frequency stability in the coherent transport of an optical frequency over a fiber-optic link. Both technical and fundamental limitations to

Trace detection is a primary strategy for thwarting terrorism activities in the US and abroad. The development of effective reference materials and methods for this purpose relies on fundamental knowledge regarding the size, mass, morphologies, and

The push to mass production of patterns with sub-100 nm dimensions will require nanometer level control of feature size, including line edge roughness (LER). Control of LER and sidewall roughness within the length scale of individual molecules requires a
Electron-molecule collisions are among the most fundamental processes in gas discharges. They are also the precursors of the ions and the radicals which drive the etch, cleaning, or deposition processes in plasma reactors. Hence, there is a need for a

Stable, accurately measured wavelength references can be used for wavelength calibration of instruments. We discuss both fundamental and artifact wavelength calibration references and give examples of how they can be used during optical component
Low-temperature plasma applications require detailed understanding of the physical and chemical processes occurring in the plasmas themselves. For instance, as the push for smaller feature sizes and higher quality devices in the semiconductor industry has
