Fires aboard U.S. naval ships pose a threat not only to human life, but to ship survivability and combat readiness. The U.S. Navy recognized the need to upgrade and utilize state of the art fire fighting equipment, reduce the flammability of materials used on ships and to employ methods to control fire propagation. This paper focuses on the historical development of a method to control fire propagation from compartment to compartment via the ships electrical cable system. The jacket insulation material on the cables is plasticized polyvinyl chloride (PVC). These cables will ignite when exposed to a fire source and transport the fire along the cable runs. The Navy, being cognizant of the potential disasterous effects of electrical cable fires, implemented programs to assess the problem. Actual shipboard fire characteristics of cables were studied in conjunction with evaluating methods and materials to control ignition and flame spread. The development and testing of a fire protective intumescent coating to meet the Navy's requirements to control fire propagation along cableways on existing ships is delineated.

As a piezoelectric substrate for surface acoustic wave devices, the LST cut quartz has good temperature characteristics and low propagation loss. However, as the thickness of the metal electrodes on the substrate surface is increased, propagation loss also increases. Further, the electromechanical coupling coefficient is small. In this paper, a cut angle of the quartz substrate is sought that has excellent temperature stability, low propagation loss, and a large electromechanical coupling coefficient in the present of metal electrode films. For the rotated Y-cut substrate in the neighborhood of the LST cut, the propagating surface acoustic wave (SAW) merle changes from the leaky surface wave to the Love wave-type surface acoustic wave for which. no propagation loss occurs in theory while the electromechanical coupling coefficient increased to 0.5 percent at the maximum if gold is used for the electrodes and the propagation direction of the SAW is shifted from the X axis. This is shown by simulation. By experiment, it is shown that the second-order temperature coefficient is on the same order as that of the ST-cut quartz substrate.

Product Costing and Inventory Accounting: A New Approach to an Old Problem

Journal of Applied Corporate Finance 2005年第2‐3期16卷

作者： Richard D. Rosson President and Founder of Vantage Point Management Systems LLC. He has more than ten years of experience in manufacturing and materials management having served in a variety ofpositions including production supervisor process improvement coordinator inventory analyst materials manager and production control manager. Mr. Rosson holds a Master of Science degree in Management from the MIT Sloan School of Management and is Certified in Integrated Resource Manage‐ment (CIRM) by the American Production and Inventory Control Society (APICS). From 1989 through 1991 he served as a Financial Policy Analyst at Stern Stewart & Company New York.

Traditional methods of accounting—including full‐absorption accounting, labor and cost standards, overhead allocations, and variance analysis–can stand in the way of attempts by managers and others to improve their company's overall performance and the ability to compete globally. Many companies have recognized the need to shift the role of accounting toward higher‐value, more strategic tasks, such as financial and operational analysis, tactical decision support, and even process improvement and reengineering. But the accounting tools at their disposal often prove inadequate. In fact, there is a core conflict between the need to provide accurate and consistent financial reports for external consumption–reports that comply in all respects with GAAP, Sarbanes‐Oxley, SEC requirements, and the like–and the need for value‐relevant and informative reports for internal management purposes. The author proposes using multiple sets of financial reports, all deriving from a single, common database, to meet external reporting requirements while addressing the distortions and limitations of GAAP for internal purposes. In particular, he has developed a new approach called Value Added Accounting that eliminates the distortions of full‐absorption accounting but that uses GAAP financial statements as its starting point. The article describes the key adjustments, presents a case study, and discusses how VAA aligns with Lean Manufacturing, Quick Response Manufacturing, Just‐In‐Time, and other common process improvement initiatives.

Meshless approach based on MLS with additional constraints for large deformation analysis

In the present work, we are interested to develop a meshless approach, based on the strong form MLS approximation with additional constraints, to solve the nonlinear elastic and elsto-plastic problems for regular and irregular distribution of points. We adopt a plastic behavior law based on the total deformation theory, which is very convenient when the physical nonlinearity is more important than the effect of irreversible process and the loading history. In plasticity, one encounters discontinuities of rigidity where the application of asymptotic developments seems difficult or impossible. To apply the Taylor series expansion, regularization methods have been adapted. The strong form MLS approximation allows us to avoid the inconvenient of the numerical integration, while the asymptotic developments help us to reduce the computation cost observed in the incremental law of plasticity and the iterative methods. For irregular points distribution, we can get an ill-posed least squares problems due to a singular moment matrix of MLS approximation. To avoid this difficulty, we propose a modified MLS approximation by introducing additional constraints which allows to increase the error functional used in the derivation of the shape functions.

A coupled Meshless-FEM method based on strong form of Radial Point Interpolation Method (RPIM)

引用

Journal of Physics: Conference Series 2021年第1期1743卷

In this present work, we are implementing a novel hybrid method based on the coupling of RPIM in strong form and Finite Element Method (FEM). The basic idea is to ensure the coupling between the two methods through the collocation technique based on RPIM interpolation. This technique is used to evaluate the local equations of the problem at the interface between FEM and RPIM regions. We can avoid numerical integrations of a big part of nodes using the strong form of RPIM. Numerical studies show that this method gives reasonably accurate results consistent with the theory.
