  • Surgical Foundations: Essentials of Thoracic Surgery
    Circulation, 2004
    Co-Authors: Harold L. Lazar
    Abstract:

    Larry R. Kaiser, Sunil Singhal 366 pp. Philadelphia, Pa: Elsevier Mosby; 2004. $79.00. ISBN 0-8151-2613-1 Kaiser and Singhal have chosen not to write an authoritative reference on the practice of thoracic surgery, but instead have produced an easily readable text that would be useful to readers such as medical students and surgical residents who wish to acquire the basic fundamentals of the practice of thoracic surgery. The beginning of each chapter contains a list of key topics that focus on the most important areas to be covered in that chapter. Key references are provided at the end of each chapter to supplement the information provided in the text. The first 2 chapters provide an excellent review of thoracic anatomy …

  • The Growth of Entire Functions Defined by Laplace–Stieltjes Transforms Related to Proximate Order and Approximation
    Journal of Function Spaces, 2020
    Co-Authors: Wen Ju Tang, Jian Chen
    Abstract:

    In this article, we discuss the growth of entire functions represented by Laplace–Stieltjes transform converges on the whole complex plane and obtain some equivalence conditions about proximate growth of Laplace–Stieltjes transforms with finite order and infinite order. In addition, we also investigate the approximation of Laplace–Stieltjes transform with the proximate order and obtain some results containing the proximate growth order, the error, , and , which are the extension and improvement of the previous theorems given by Luo and Kong and Singhal and Srivastava.

  • Improvement of cavitation mass transfer modeling by including Rayleigh–Plesset equation second order term
    European Journal of Mechanics - B Fluids, 2020
    Co-Authors: Linlin Geng, Jian Chen, Xavier Escaler
    Abstract:

    Abstract The current study evaluates the effect of taking into account the second order term of the Rayleigh–Plesset equation for the numerical simulation of cavitation with homogeneous mixture models. For that, the corrected expression for the condensation mass transfer rate has been mathematically derived and implemented in the original Zwart and Singhal cavitation models. Two tests cases of steady sheet cavitation around a NACA 0009 hydrofoil and a hemi-spherical body at different cavitation coefficients have been simulated with both the original and the corrected models. The results demonstrate that the pressure distribution at the closure region of the attached cavity is better predicted and a stronger pressure gradient is obtained. Consequently, the cavity length is slightly shortened and it gets closer to the experimental observations. Another test case of cloud cavitation around a NACA 0009 hydrofoil has confirmed that the prediction of the shedding frequency is also improved with the corrected Zwart model because the maximum cavity length is significantly reduced. In conclusion, the proposed modification of the Zwart and Singhal cavitation models helps to ameliorate the numerical simulation of both steady and unsteady cavitation flows.

  • a new summation identity for the srivastava Singhal polynomials
    Journal of Mathematical Analysis and Applications, 2004
    Co-Authors: Kung-yu Chen
    Abstract:

    Abstract In his recent investigations involving differential operators for some generalizations of the classical Laguerre polynomials, H. Bavinck [J. Phys. A Math. Gen. 29 (1996) L277–L279] encountered and proved a certain summation identity for the classical Laguerre polynomials. The main object of this sequel to Bavinck's work is to prove a generalization of this summation identity for the Srivastava–Singhal polynomials. The demonstration, which is presented here in the general case, differs markedly from the earlier proof given for the known special case. It is also indicated how the general summation identity can be applied to derive the corresponding result for one class of the Konhauser biorthogonal polynomials.

  • Production, Manufacturing and Logistics Production quality and yield assurance for processes with multiple independent characteristics
    2006
    Co-Authors: W. L. Pearn
    Abstract:

    Process capability indices have been widely used in the manufacturing industry providing numerical measures on process potential and process performance. Capability measure for processes with single characteristic has been investigated extensively, but is comparatively neglected for processes with multiple characteristics. In real applications, a process often has multiple characteristics with each having different specifications. Singhal [Singhal, S.C., 1990. A new chart for analyzing multiprocess performance. Quality Engineering 2 (4), 397–390] proposed a multi-process performance analysis chart (MPPAC) for analyzing the performance of multi-process product. Using the same technique, several MPPACs have been developed for monitoring processes with multiple independent characteristics. Unfortunately, those MPPACs ignore sampling errors, and consequently the resulting capability measures and groupings are unreliable. In this paper, we propose a reliable approach to convert the estimated index values to the lower confidence bounds, then plot the corresponding lower confidence bounds on the MPPAC. The lower confidence bound not only gives us a clue minimum actual performance which is tightly related to the fraction of non-conforming units, but is also useful in making decisions for capability testing. A case study of a dual-fiber tip process is presented to demonstrate how the proposed approach can be applied to in-plant applications. � 2005 Elsevier B.V. All rights reserved.
