Study on Digital Style Design (2010)

In this paper, a novel approach for designing grain patterns based on digital technology is proposed. In the previous paper, the basic tree growth model was developed by investigating the basic growth-features of trees and the responding growth features on growing environment conditions : daylight hours, precipitation, temperature, and the ground inclination angle. The basic tree growth model was constructed by using the electric charge method which can easily represent the trunk and branches and could generate a variety of woodgrain patterns by changing the growing environment conditions. The tree model developed in the previous paper enables to reproduct the trunk and branches. However, it is required to make a more realistic digital tee model. In this paper, in order to generate more natural woodgrain patterns which can be used for industry design, the method to construct a more precise digital trees model is proposed. A design system of grain patterns is developed based on the proposed method. The digital woodgrain patterns generated by the system are evaluated.
Using Education Research to Develop Waves Courseware (1996)

The topic of waves forms the foundation of many branches of physics, such as acoustics, opties, and quantum mechanics.Thus it is essential that students of physics acquire a good understanding of waves if they wish to understand many other aspects of physics.Unfortunately, this topic presents a serious obstacle to many students, who often find it abstract and too mathematical.In order to help make the topic more accessible to students, Aronsl recommends that waves be introduced from a kinematical perspective by first considering graphical representations of single, transverse pulses.In this way, students are provided with a bridge from a more familiar and more concrete domain, kinematics, to a less familiar and more abstract domain, waves.Moreover, this approach to waves provides a context in which students can apply, reinforce, and extend graphing skills initially learned in kinematics.From a kinematical perspective, transverse displacement (y) of a point on a string is analogous to displacement in one dimension, and the (transverse) velocity of that point can be found by taking the slope of a graph of (transverse) displacement versus time.However, the string is not a single particle, nor is it a rigid body that moves as a whole.Rather, it consists of many pieces that do not move together.Thus, transverse displacement depends not only on the time of observation but also on which piece of the string is observed.Consequently, a new variable, position along the string (x), is needed.The motion of a pulse on a string thus provides a context in which to introduce the notion of a function of two independent variables.Another important aspect of waves is the need to distinguish between the motion of the pulse and the motion of particles of the medium as the pulse passes through them.This distinction can be highlighted by plotting an x versus t
Transverse effects in optical bistability and superfluorescence (1982)

Abstract : The interaction of a light beam with matter has varying degrees of dependence on the transverse profile of the beam. Two topics are considered here. The first topic, superfluorescence, involves the coherent emission generated by an initially inverted two-level medium. Calculations in the past have included either quantum fluctuations in the initial conditions or transverse effects, but never both. The calculations presented here include both transverse effects and quantum fluctuations. The results of the theoretical calculations are in good agreement with previous experimental results, both quantitatively in terms of time delay averages and distributions and also qualitatively in terms of pulse shapes. The second topic considered, optical bistability, involves devices which exhibit two stable output light intensities (a high and a low branch) over a limited range of input light intensities. Simulations performed here show the effect of diffraction, measured in terms of the Fresnel number, on how much of the device becomes bistable. It was found that for small Fresnel number cases, the entire device become bistable. For high Fresnel number cases, only part of the device becomes bistable while the rest of the device remains low transmitting. The results of an experiment performed are consistent with the simulations. (Author)
Are Stanislavski and Brecht Commensurable? (1964)

“How does Brecht’s system differ from Stanislavski’s?” I have often heard this question asked, sometimes in exactly these words, and probably we shall all live to see the question appear in much this form on college examination papers. I recall, too, that as a young admirer of Brecht’s, nearly twenty years ago, I myself described an actor in one of his plays as having gone “beyond Stanislavski.” Will the acting profession soon be divided between Method actors and Brechtians?

Micromachined three-axis thermal accelerometer with a single composite heater (2011)

A novel three-axis thermal accelerometer is designed, fabricated, and characterized in this paper. The device includes two half sensor plates attached to buckled cantilevers to form out-of-plane structures. Cantilevers are assembled by a single push of a microprobe and preserve their shapes when they latch into stoppers anchored to the substrate. The fabrication process is based on surface micromachining on silicon substrates using polyimide as the structural layer and amorphous silicon as the sacrificial layer. The fabricated devices are individually packaged and characterized. Using a total heater power of 2.5 mW, the X, Y, and Z axes, respectively, showed sensitivities of 66, 64, and 25 µV g−1. Compared to the earlier versions of the same class accelerometers, the fabricated single heater accelerometer demonstrates more than fourfold sensitivity improvement.
Effect of high frame rates on 3D video quality of experience (2014)

In this paper, we study the effect of 3D videos with increased frame rates on the viewers' quality of experience. We performed a series of subjective tests to seek the subjects' preferences among videos of the same scene at four different frame rates: 24, 30, 48, and 60 frames per second (fps). Results revealed that subjects clearly prefer higher frame rates. In particular, Mean Opinion Score (MOS) values associated with the 60 fps 3D videos were 55% greater than MOS values of the 24 fps 3D videos.
Kinetics of the Transformation of Trichloroethylene and Tetrachloroethylene by Iron Sulfide (1999)

The transformation of trichloroethylene (TCE), tetrachloroethylene (PCE), and 1,1-dichloroethylene (1,1-DCE) by 10 g/L (0.5 m2/L) FeS in aqueous solution at pH 8.3 was studied in batch experiments. TCE and PCE were transformed by FeS with pseudo-first-order rate constants, corrected for partitioning to the sample headspace, of (1.49 ± 0.14) × 10-3 h-1 (TCE) and (5.7 ± 1.0) × 10-4 h-1 (PCE). A 17% decrease in the concentration of 1,1-DCE was observed over 120 days; however, no reaction products were detected. TCE and PCE transformation data were fit to a rate law assuming transformation of TCE via parallel reaction pathways to acetylene and cis-1,2-dichloroethylene (cis-DCE) and transformation of PCE via parallel reaction pathways to acetylene and TCE. Acetylene was the major reaction product for both TCE and PCE. Determination of rate constants for each reaction pathway indicated that TCE was transformed to acetylene 11.8 ± 1.1 times faster than to cis-DCE and that PCE was transformed to acetylene 8.2 ± 1.8 times faster than to TCE. Additional minor reaction products were vinyl chloride (VC) for TCE and cis-DCE for PCE. Detection of acetylene as the major product of both TCE and PCE transformation by FeS contrasts with the sequential hydrogenolysis products typically observed in the microbial transformation of these compounds, making acetylene a potential indicator of abiotic transformation of TCE and PCE by FeS in natural systems.
Advanced Cooling of 3D ICs With Nanoparticle Packings (2017)

Thermal-aware techniques for 3D ICs have shown that high temperatures dramatically reduce the lifetime and the reliability of the 3D ICs with utilizing the third dimension. Hence, thermal management has been very crucial for the further improvement of the 3D IC architecture. There has been some thermal management strategies suggested at the micro/nano scale to alleviate the nonlocal heat dissipation; however, many solution methods such as liquid cooling have challenges and create many problems. In this paper, we propose nanoparticle based interfacial cooling to improve the thermal transport due to surface phonon polariton coupling and to reduce the thermal resistance between the interfaces. We demonstrate the efficiency of the heat dissipation from the proposed structure for 3D ICs.
Elaboration of transparent conductive oxide films for flexible organic electroluminescent devices (2006)

In this study, we presented high-performance flexible organic light-emitting diodes (FOLEDs); to do so, we prepared indium-tin oxide (ITO) thin layers by ion beam sputtering (IBS) on polyethylene terephtalate (PET) substrates in soft low temperature conditions. The IBS technology seems well adapted to us to adjust the conduction level of the interface films to the one of the various organic materials making up the fabrication processes of the organic optoelectronic components; moreover this technique does not require a high substrate temperature or an annealing after ITO deposition to crystallize the obtained layers. Because of the great number of deposition parameters (oxygen flow, substrate temperature, deposition rate...) playing interdependent roles and strongly influencing the electrical, optical and structural properties of the layers, we optimized the effects of these different parameters separately by using electrical and optical characterizations as well as X-ray diffraction analyses. The performances of FOLEDs on PET substrate with different ITO thicknesses were investigated and compared to the ones of a conventional organic light-emitting diode realized on glass substrate and according to the same device configuration.
Experimental Study of Symmetric Microstrip Bends and Their Compensation (1978)

An experimental study of microstrip bends is described. For right-angle corners, equivalent circuit parameters covering a wide range of frequencies, linewidths, and permittivities are presented and compared with the limited theoretical values available. The influence of mitering or rounding of the corner was investigated, and useful empirical expressions are given for the optimum miter.
New reversible full‐embeddable information hiding method for vector quantisation indices based on locally adaptive complete coding list (2014)

Steganography based on vector quantisation (VQ)‐compressed indices is widely used in information hiding. In this study, the authors propose a new reversible information hiding method for VQ indices using an on‐line generated locally adaptive complete coding list. The complete coding list guarantees that all VQ indices can embed one or two secret bits which efficiently increase the embedding capacity. Additionally, they propose a mixed coding method with an index position threshold by exploring the biased‐distribution of locally complete coding indices in order to reduce the bit rate. Experimental results demonstrated that the authors proposed method has a better performance in embedding capacity, bit rate and the embedding‐efficiency compared with the four information hiding methods.
Development of an integrated in-situ remediation technology. Draft topical report for Task {number_sign}7.2 entitled ``Field scale test`` (January 10, 1996--December 31, 1997) (1997)

Contamination in low-permeability soils poses a significant technical challenge to in-situ remediation efforts. Poor accessibility to the contaminants and difficulty in delivery of treatment reagents have rendered existing in-situ treatments such as bioremediation, vapor extraction, and pump and treat rather ineffective when applied to low permeability soils present at many contaminated sites. The technology is an integrated in-situ treatment in which established geotechnical methods are used to install degradation zones directly in the contaminated soil and electro-osmosis is utilized to move the contaminants back and forth through those zones until the treatment is completed. The present Topical Report for Task {number_sign}7.2 summarizes the Field Scale Test conducted by Monsanto Company, DuPont, and General Electric.

Antenna array excited by the radial waveguide (2014)

In the paper a number of design solutions of helical radiator arrays exited by radial waveguide was presented. It was also presented the power divider 1:18 executed on the base of the radial waveguide. The single, 18 elements array of radiators was described. Calculating results of reflection coefficient and radiation characteristics were presented as well. The analysis of large arrays containing 2 or 4 single antennas was carried out. It was indicated possibility of obtaining the monopulse characteristics in such large arrays. Calculating were conducted with the use of the CST MicroWave Studio computer program.
Stability Analysis Considering Dual Physical Constraints of Parallel-connected Virtual Synchronous Generators forming Microgrids (2019)

Although virtual synchronous generator (VSG) is a promising solution to low inertia and damping of the power electronics-based power system, improper parameter design will lead to instability of such a system. In this paper, a VSG parameter design strategy is proposed by considering both AC and DC restraints for a paralleled inverters system, where the active power output of VSG is restricted by the maximum power limit of the converters in AC side, with the energy supply bounded by the energy margin of power source in DC side. Detailed stable operation boundaries are investigated using small-signal mode by considering the dual physical constraints and the stable constraints. Therefore, the proposed parameter tuning method can not only provide enough virtual inertia for stable operation of the system, but also satisfy the power and energy restraints in practice. Detailed simulation results verified the effectiveness of the proposed strategy.
Cost-Based Search Ordering for Rate-Constrained Motion Estimation Applied to HEVC (2018)

In the context of motion estimation for video coding, combining a successive elimination algorithm (SEA) with a motion estimation algorithm reduces the number of computed cost functions without impact on rate or distortion. The SEAs use the sum of absolute differences to eliminate motion vector candidates in the search area that cannot improve the current minimum. The novelty in this paper is that instead of relying on a static geometric pattern (i.e., like a spiral), we proposed a dynamic algorithm that creates a cost-based search orderings. A dynamic cost-based search ordering not only improves elimination but also allows for early termination which removes, on average, 61% of the block-matching loop iterations performed by the rate-constrained successive elimination algorithm (RCSEA). Our experiments show that the proposed solution is 5 times faster than the high efficiency video coding (HEVC) HM encoder software in full search mode with a 0.02% impact on BD-Rate. This is twice the speed of the HEVC HM software encoder using only the RCSEA.
Structure-Function Relationships in l-Amino Acid Deaminase, a Flavoprotein Belonging to a Novel Class of Biotechnologically Relevant Enzymes (2016)

l-Amino acid deaminase from Proteus myxofaciens (PmaLAAD) is a membrane flavoenzyme that catalyzes the deamination of neutral and aromatic l-amino acids into α-keto acids and ammonia. PmaLAAD does not use dioxygen to re-oxidize reduced FADH2 and thus does not produce hydrogen peroxide; instead, it uses a cytochrome b-like protein as an electron acceptor. Although the overall fold of this enzyme resembles that of known amine or amino acid oxidases, it shows the following specific structural features: an additional novel α+β subdomain placed close to the putative transmembrane α-helix and to the active-site entrance; an FAD isoalloxazine ring exposed to solvent; and a large and accessible active site suitable to bind large hydrophobic substrates. In addition, PmaLAAD requires substrate-induced conformational changes of part of the active site, particularly in Arg-316 and Phe-318, to achieve the correct geometry for catalysis. These studies are expected to pave the way for rationally improving the versatility of this flavoenzyme, which is critical for biocatalysis of enantiomerically pure amino acids.
The photochemical production of HONO during the heterogeneous hydrolysis of NO2 (2004)

The heterogeneous hydrolysis of NO2 in thin water films, a major source of HONO and hence OH radicals in polluted urban atmospheres, has been previously reported to be photoenhanced (H. Akimoto, H. Takagi and F. Sakamaki, Int. J. Chem. Kinet., 1987, 19, 539, ) which has important implications for OH production both in environmental chambers and in the lower atmosphere. We report here studies of the impact of 320–400 nm radiation on HONO formation during the heterogeneous NO2 hydrolysis at 296 K. The experiments were carried out in a borosilicate glass cell using long path Fourier transform infrared (FTIR) spectroscopy with three initial NO2 concentrations (20, 46, and 54 ppm) at relative humidities of 33, 39, and 57%, respectively. Nitrous acid was first allowed to accumulate from NO2 hydrolysis in the dark, and then the mixture of reactants and products was irradiated. The measured concentration–time profiles of the gases were compared to the predictions of a kinetics model developed for this system. The initial loss of HONO upon irradiation was consistent with its photolysis and known secondary gas phase chemistry without any photoenhancement. While the fundamental NO2 heterogeneous hydrolysis is not itself photoenhanced, there is clear evidence in these experiments for the generation of gas phase HONO by photolysis of adsorbed HNO3 formed during the heterogeneous hydrolysis. The mechanisms and atmospheric implications of HONO as well as NO2 formation by the photolysis of surface-adsorbed HNO3 are discussed.

A tactical broadband omnidirectional antenna (2008)

In this paper, a vertically polarized broadband antenna with an adjustable shape for specific applications in the VHF and UHF bands is proposed. This antenna is a compact monopole with a pseudo-conical shape set on a rectangular ground plane, partially made of wire netting. A part of the radiating element is made of metallic pipes which are bent to minimize the height of the shape without deteriorating the impedance matching. The bent pipes and the wire netting of the ground plane can be removed in order to dramatically reduce the size of the antenna for applications in high-frequency range. As a result, two compact structures relatively to the wavelength are obtained with a vertical size of respectively lambda <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">LF</sub> /6.25 for the low-frequency mode (100-500 MHz) and lambda <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">LF</sub> /7.2 for the high-frequency mode (415-915 MHz) (lambda <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">LF</sub> is the wavelength associated to the lowest frequency of the covered bandwidth). The structures operate with good gain and radiation patterns in both E- planes and H-planes.
Application of the vector Bragg scattering wave-number condition to obtaining turbulent field variables (1992)

Using the concept of the vector Bragg wave-number scattering condition, described in the previous presentation, the results of laboratory experiments on high-frequency broad bandwidth bistatic acoustic scattering from a buoyant turbulent plume are described. Estimates of a variety of characteristics of the turbulent field are made. These include a real time estimate of the spatial structure and wave-number spectra of the turbulent temperature field, and a simultaneous and real time estimate of the velocity field and the velocity variance field. Examination into the occurrence of organized structure will be made. Discussion of the appropriateness of classical turbulence theory to the results will be made with emphasis given to the issue of inhomogeneity and anisotropy.
Quantitative evaluation of cardiac valvular insufficiency using computerized radioisotope angiocardiograms (1974)

A new method for determining cardiac ejection and regurgitant fractions has been developed which is based upon a pulsitile flow model for the heart. Radioisotope angiocardiograms obtained using an Angertype scintillation camera are recorded at 20 frames per second in a minicomputer interfaced to an interactive display after injection of a concentrated bolus of 99Tc-pertechnetate in the pulmonary arterial wedge position or into the vena cava. Counts recorded over the atrium and the ventricle are corrected for background frame-by-frame using suitable background test regions. The resulting activity against time curves are then used to compute forward ejection fractions for the two chambers and regurgitant fractions for the two valves on the side of the heart under investigation.
Progress toward developing a novel module architecture for increased reliability and reduced costs (2014)

Module reliability has a direct impact on the levalized cost of energy, and reliability issues for thin film PV have been consistently reported. Direct Solar LLC is developing a new module architecture for thin film PV that has robustness to moisture and excellent adhesion under UV light exposure. Process cycle times for each manufacturing step is under 1 minute using low capital cost, small footprint tooling. The patent pending architecture utilizes a specialized two part edge seal. The modules are fabricated without lamination, vacuum pressing or module heating. An initial version of this design has passed IEC 61646 and UL 1703 certification tests and 4500+hrs. of the rigorous 85 C/85% relative humidity “damp heat test”.
