SPECTRO-TIMING STUDY OF GX 339-4 IN A HARD INTERMEDIATE STATE (2016)

We present an analysis of Nuclear Spectroscopic Telescope Array observations of a hard intermediate state of the transient black hole GX 339−4 taken in 2015 January. With the source softening significantly over the course of the 1.3 day long observation we split the data into 21 sub-sets and find that the spectrum of all of them can be well described by a power-law continuum with an additional relativistically blurred reflection component. The photon index increases from ∼1.69 to ∼1.77 over the course of the observation. The accretion disk is truncated at around nine gravitational radii in all spectra. We also perform timing analysis on the same 21 individual data sets, and find a strong type-C quasi-periodic oscillation (QPO), which increases in frequency from ∼0.68 to ∼1.05 Hz with time. The frequency change is well correlated with the softening of the spectrum. We discuss possible scenarios for the production of the QPO and calculate predicted inner radii in the relativistic precession model as well as the global disk mode oscillations model. We find discrepancies with respect to the observed values in both models unless we allow for a black hole mass of ∼100 M⊙, which is highly unlikely. We discuss possible systematic uncertainties, in particular with the measurement of the inner accretion disk radius in the relativistic reflection model. We conclude that the combination of observed QPO frequencies and inner accretion disk radii, as obtained from spectral fitting, is difficult to reconcile with current models.
Toward a Critical Biography: The Singing Life of C. J. Johnson (1913-). Preliminary Considerations (1987)

C. J. Johnson is renowned as a great hymn singer and song leadercomposer in the Missionary Baptist churches. He may be an obscure, unknown figure beyond the sphere of inner-city record shops and radio stations, where his recordings are available and broadcast, but the impact of his work, through more than twenty commercial recordings and countless revival appearances, has been strong in churches that remain rooted in black oral-tradition worship practices. Perhaps, in the telling of his life, an estimate of the traditions themselves can become more precise and meaningful. This present study is preliminary, providing information taken from taped interviews with the subject and a historiographical survey of the singing tradition in which he has been a leader for more than sixty years.
On the scale and performance of cooperative Web proxy caching (1999)

While algorithms for cooperative proxy caching have been widely studied, little is understood about cooperative-caching performance in the large-scale World Wide Web environment. This paper uses both trace-based analysis and analytic modelling to show the potential advantages and drawbacks of inter-proxy cooperation. With our traces, we evaluate quantitatively the performance-improvement potential of cooperation between 200 small-organization proxies within a university environment, and between two large-organization proxies handling 23,000 and 60,000 clients, respectively. With our model, we extend beyond these populations to project cooperative caching behavior in regions with millions of clients. Overall, we demonstrate that cooperative caching has performance benefits only within limited population bounds. We also use our model to examine the implications of future trends in Web-access behavior and traffic.
Apodized photonic crystal waveguide gratings (2006)

Apodized photonic crystal (PC) waveguide gratings are proposed to suppress sidelobes which appear in reflection spectra of usual PC waveguide gratings. By using specific functions (Gauss and Gauss-cosine functions) for the longitudinal refractive index distribution, it is possible to suppress sidelobes in the reflection spectra of PC waveguide gratings efficiently. The apodization is realized by simply changing diameters of dielectric pillars adjacent to the PC waveguide core. It is shown that by using Gauss-cosine functions for the apodization, Bragg frequency of the waveguide grating becomes insensitive to the magnitude of perturbation leading to the possibility of designing waveguide gratings with arbitrarily Bragg frequency and bandwidth by modulating geometrical parameters only.

Decision-Making with the AHP: Why is the Principal Eigenvector Necessary? (2001)

We will show here that the principal eigenvector of a matrix is a necessary representation of the priorities derived from a positive reciprocal pairwise comparison consistent or near consistent matrix. A positive reciprocal n by n consistent matrix W = (w ij ) satisfies the relation w ik = w ij w jk . If the principal eigenvector of W is w=(w 1 , ,w n ) the entries of W may be written as w ij = w i /w j . Matrices A = (a ij ) that are obtained from W by small positive reciprocal perturbations of w ij , known as near consistent matrices, are pivotal in representing pairwise comparison numerical judgments in decision making. Since W is always of the form w ij = (w i /w j ) a perturbation of W is given by a ij = (w i /w j ) ij and their corresponding reciprocals a ji = (w j /w i ) (1/ ij ). A priority vector for use in decision making that captures a linear order for the n elements compared in the judgment matrix can be derived for both consistent and near consistent matrices, but it is meaningless for strongly inconsistent matrice except if they are the result of random situations that have associated numbers such as game matches where the outcomes do not depend on judgment. It is shown that the ratios w i /w j of the principal eigenvector of the perturbed matrix are close to a ij , if and only if the principal eigenvalue of A is close to n. We then show that if in practice we can change some of the judgments in a judgment matrix, it is possible to transform that matrix to a near consistent one from which one can then derive a priority vector. The main reason why near consistent matrices are essential is that human judgment is of necessity inconsistent, which if controllable, is a good thing. In addition, judgment is much more sensitive and responsive to large than to small perturbations, and hence once near consistency is reached, it becomes uncertain which coefficients should be perturbed with small perturbations to transform a near consistent matrix to a consistent one. If such perturbations were forced, they would seem arbitrary and can distort the validity of the derived priority vector in representing the underlying real world problem.
Droplet Mobility on Slippery Lubricant Impregnated and Superhydrophobic Surfaces under the Effect of Air Shear Flow (2021)

The focus of this study is to investigate and compare the behavior of a droplet on superhydrophobic (SHS) and slippery lubricant impregnated (SLIPS) surfaces under the effect of air shear flow. In this regard, both experimental and numerical analyses have been conducted to compare their performance on droplet mobility under different air speeds. Two different lubricants have been utilized to scrutinize their effect on droplet movement. The numerical simulations have been performed based on the volume of fluid method coupled with the large eddy simulation turbulent model in conjunction with the dynamic contact angle method in addition to a model that can represent the effect of lubricants on slippery surfaces. The numerical simulations are compared with the experimental study in order to shed light on the underlying mechanisms. The results showed that under the same conditions, the critical velocity for droplet movement on the superhydrophobic surfaces is lower than that on the slippery lubricant impregnated surfaces due to the smaller droplet base diameter and the larger contact angle. The hydrodynamics of droplet mobility on superhydrophobic surfaces exhibits a rolling behavior while for the slippery lubricant impregnated surfaces a combination of rolling and sliding is observed. Beyond the critical airflow speed, a complete droplet shedding on all surfaces occurs. The wetting length and position of the droplet on superhydrophobic and slippery surfaces have been measured. On slippery surfaces, the speed of droplets is greatly affected by the lubricant properties while similar behavior in the wetting lengths is observed.
Standard cell design with regularly placed contacts and gates (2004)

The layout strategies of standard cells with regularly-placed contacts and gates are studied. The regular placement enables more effective use of resolution enhancement technologies, which in turn allows a reduction of critical dimensions. Although regular placement of contacts and gates adds restrictions during cell layout, the overall circuit area can be made smaller and the number of extra masks and exposures can be kept to the lowest by careful selection of the grid pitch, using template-trim lithography method, allowing random contact placement in the vertical direction, and using rectangular rather than square contacts. Three different fabrication-friendly layouts are compared in this study. The average area change of 64 standard cells in a 130nm library range from -4.2% to -1.2% with the 3 fabrication-friendly layout approaches. The area change of 5 test circuits using the 3 approaches range from -5.4% to +2.6%. Power consumption and intrinsic delay also improve with the decrease in circuits area, which is verified with the examination results.
Bessel–Thompson Filter Using Double-Series-Coupled Microring Resonator (2008)

We analyzed the dispersion characteristics of double-series-coupled microring resonator filter and found that the coupling efficiency between resonators for the zero third-order dispersion (Bessel-Thompson) filter is one-third of that of a flat passband (Butterworth) filter. By controlling the coupling efficiencies between waveguides, the flat-top group delay response (Bessel-Thompson filter response) was realized. However, under the symmetric arrangement of coupling efficiency, the Bessel-Thompson filter lost transmittance by 1.25 dB. Thus we found the optimum condition of coupling efficiencies for achieving zero third-order dispersion (flat-group delay) with unity transmittance is an asymmetric arrangement of coupling efficiencies.
Average Modelling of State-of-the-Art Ultra-low Power Energy Harvesting Converter IC (2018)

Micro-energy harvesting from environmental sources is a promising technology for mobile or unobtrusive battery powered Internet of Things devices with constrains in terms of size and weight. Special integrated circuits aim to manage the voltage matching and power control in between the energy harvesting transducer and the storage. Hence, models to simulate the energy behaviour of these systems are important tools for system engineers. In this paper, a neuronal network model is presented to predict the performance of two state-of-the-art integrated circuits. Required model inputs are voltage and current from the energy harvesting transducer and the voltage level of the storage element. Model provides conversion efficiency as its output. Three different datasets have been collected with in-field experiments to build and evaluate the proposed model. Evaluation of the developed model on all datasets shows efficiency prediction root mean square error of less than 2 %.

Diagnosis-Free Self-Healing Scheme for Open-Circuit Faults in Dual Three-Phase PMSM Drives (2020)

Aiming at tolerating common electric faults of multiphase motor drives comprehensively and minimizing the adverse impacts from the remedial scheme itself, a diagnosis-free self-healing scheme is put forward for the open-circuit faults of dual three-phase permanent-magnet synchronous motor (PMSM) drives. First, the self-healing mechanisms of dual three-phase PMSM drives are analyzed in detail. On the basis of theoretical analysis, the repressed self-healing capability of the dual three-phase PMSM drives is fully released by optimizing the current references on harmonic subspace. Since the diagnosis process is not required in the proposed self-healing scheme, the misdiagnosis problem and the prolonged damage caused by the additional time cost of diagnosis can be fundamentally avoided. The proposed self-healing scheme can be generally applied to open-switch faults, single open-phase faults, and multiple open-phase faults in the multiphase motor drives. No change is required for the machine model, modulation strategy, or control framework under different open-circuit faults. Thus, the complex transition strategies among different fault-tolerant control methods for different faults can be avoided, and the adverse impacts from the remedial scheme itself can be minimized. Experimental verification is presented to prove the validity of the proposed self-healing scheme.
Fragilisation par le zinc liquide des aciers haute résistance pour l'automobile (2013)

\nCette étude présente les investigations menées sur la fragilisation par le zinc liquide d'un acier électro-zingué. La caractérisation mécanique par essais de traction à haute température montre un important puits de ductilité entre environ 700 ∘C et environ 950 ∘C. L'observation au MEB des éprouvettes de traction indique que, dans la gamme de température observée pour laquelle il y a fragilisation, on a mouillage intergranulaire des joints de grains de l'acier à l'interface acier/revêtement par des films de Zn. La corrélation entre mouillage intergranulaire thermiquement activé d'une part, et propagation de fissure lors du chargement d'autre part, est discutée.\n
Pumping-Induced Ebullition:  A Unified and Simplified Method for Measuring Multiple Dissolved Gases (2004)

The incorporation of multiple dissolved gas measurements in biogeochemical studies remains a difficult and expensive challenge. Incompatibilities in collection, handling, and storage procedures generally force the application of multiple sampling procedures for multiple gases. This paper introduces the concept and application of pumping-induced ebullition (PIE), a unified approach for routine measurement of multiple dissolved gases in natural waters and establishes a new platform for development of in situ real-time dissolved gas monitoring tools. Ebullition (spontaneous formation of bubbles) is induced by pumping a water sample through a narrow-diametertube (a "restrictor") to decrease hydrostatic pressure (PH) below total dissolved gas pressure (PT). Buoyancy is used to trap bubbles within a collection tower where gas accumulates rapidly (1 mL/min) to support multiple chemical analyses. Providing for field collection of an essentially unlimited and unified volume of gas sample, PIE afforded accurate and precise measurements of major (N2, 02, Ar), trace (CO2, N20, CH4) and ultratrace (CFC11, CFC12, CFC113, SF6) dissolved gases in Wisconsin groundwater, revealing interrelationships between denitrification, apparent recharge age-dates, and historical land use. Compared to conventional approaches, PIE eliminates multiple gas-specific sampling methods, reduces data computations, simplifies laboratory instrumentation, and avoids aqueous production and consumption of biogenic gases during sample storage. A lake depth profile for CO2 demonstrates PIE's flexibility as an in situ real-time platform for dissolved gas measurements. The apparent departures of some gases (SF6, H2, N2O, CO2) from solubility equilibrium behavior warrant further confirmation and theoretical investigation.
Linear-time dynamics for multibody systems with general joint models (2010)

Most current linear-time forward dynamics algorithms support only simple types of joints due to difficulties in computing derivatives of joint transformations up to order two. We apply the D* symbolic differentiation algorithm to a recursive formulation of forward dynamics to get a highly efficient linear-time forward dynamics algorithm supporting multibody systems with general scleronomic joints. With this new algorithm we can easily build a tree-topology multibody system with complex joint models and perform forward dynamics efficiently. The source code for the algorithm is freely available for non-commercial use.
Parametric study of chemical looping combustion for tri-generation of hydrogen, heat, and electrical power with CO2 capture (2005)

In this article, a novel cycle configuration has been studied, termed the extended chemical looping combustion integrated in a steam-injected gas turbine cycle. The products of this system are hydrogen, heat, and electrical power. Furthermore, the system inherently separates the CO2 and hydrogen that is produced during the combustion. The core process is an extended chemical looping combustion (exCLC) process which is based on classical chemical looping combustion (CLC). In classical CLC, a solid oxygen carrier circulates between two fluidized bed reactors and transports oxygen from the combustion air to the fuel; thus, the fuel is not mixed with air and an inherent CO2 separation occurs. In exCLC the oxygen carrier circulates along with a carbon carrier between three fluidized bed reactors, one to oxidize the oxygen carrier, one to produces and separate the hydrogen, and one to regenerate the carbon carrier. The impacts of process parameters, such as flowrates and temperatures have been studied on the efficiencies of producing electrical power, hydrogen, and district heating and on the degree of capturing CO2. The result shows that this process has the potential to achieve a thermal efficiency of 54% while 96% of the CO2 is captured and compressed to 110 bar. Copyright © 2005 John Wiley & Sons, Ltd.
Lesser Tuberosity Osteotomy for the Management of the Subscapularis During Total Shoulder Arthroplasty (2023)

Subscapularis integrity is critical after anatomic total shoulder arthroplasty, with failure leading to potential instability, loss of function, and revision surgery. The three well-described subscapularis mobilization techniques during total shoulder arthroplasty include tenotomy, peel, and lesser tuberosity osteotomy (LTO). While several comparative studies exist, the optimal approach remains controversial. LTO has been associated with the highest healing rates, but techniques and repair constructs are highly variable. The purpose of this article was to provide an overview of LTO with attention on radiographic assessment, repair options, and clinical outcomes.

Feature article atomic transport: A review with perspectives (1992)

Abstract This article aims to cover the highlights of more than thirty years of research carried out by Hehenkamp and his group into atomic transport and related fields. In Hume-Rothery alloys, which served as model systems, the effective charge numbers of electromigration and the heats of transport in a thermal gradient were systematically investigated, particularly by means of the stationary state technique, which proved to be very reproducible. The effective charges were found to originate from momentum transfer of the charge carriers, which also gives rise to a pronounced electronic contribution to the impurity heat of transport and determines the concentration dependence of this quantity. The investigation of transport experiments in alloys requires knowledge of the thermodynamic factor Φ of diffusion. Even in dilute noble and transition metal alloys the latter turned out to be by no means negligible. The variation of Φ upon alloying cannot be described well in the framework of regular solution models based on pairwise interaction. The strong nonlinear enhancement of solvent and solute diffusion in these alloys is interpreted in terms of the complex model of Hehenkamp et al., as being due to the formation of higher-order vacancy-impurity complexes. Non-equilibrium vacancies, recently evidenced in thermomigration and chemical diffusion might seriously affect particularly non-stationary transport experiments. Consequences for the theoretical description of atomic transport will be outlined.
