The purpose of this study is to evaluate the fitting accuracy and fracture resistance of crowns using a hybrid zirconia frame made of both porous and dense zirconia. Commercial semi-sintered zirconia, sintered dense zirconia and sintered hybrid zirconia were used. Sintered zirconia was milled using the CAD/CAM system, and semi-sintered zirconia was milled and sintered to fabricate molar crown f...

finite affine groups are given by groups of translations and di-lations on finite cyclic groups. for cyclic groups of prime orderwe develop a time-scale (wavelet) analysis and show that for alarge class of non-zero window signals/vectors, the generatedfull cyclic wavelet system constitutes a frame whose canonicaldual is a cyclic wavelet frame.

Following a recent upgrade, the Digital Video Broadcasting—Return Channel Satellite (DVB-RCS) standard sets up to support terminal mobility. In this scenario, integration with terrestrial systems becomes a primary concern to ensure network connectivity in urban areas. This article proposes an integrated satellite–terrestrial architecture for the provision of broadband services onboard high-spee...

The return link performance of conventional civil DVB-RCS transmission technology limits its direct application to air-borne satellite video transmission system. This paper studies the novel emergent DVB-RCS return link technique based on introducing adaptive parallel processing to the conventional civil DVB-RCS return link. Simulation results demonstrate that the proposed return link transmiss...

the generalization of p-frame in banach spaces is considered in this paper. the concepts of an $tilde{x}$-frame and a system conjugate to $tilde{x}$-frame were introduced. analogues of the results on the existence of conjugate system were obtained. the stability of $tilde{x}$-frame having a conjugate system is studied.

Vector potential formulation and parametric studies of electromagnetic scattering problems of a sphere characterized by the rotationally symmetric anisotropy are studied. Both epsilon and mu tensors are considered herein, and four elementary parameters are utilized to specify the material properties in the structure. The field representations can be obtained in terms of two potentials, and both...

The hierarchical real-time control systems (RCS) reference model architecture that is under development at the National Institute of Standards and Technology aims at designing and developing intelligent control for large and complex systems. A methodology being developed to create RCS-based systems exhibits many characteristics that are similar to object-oriented paradigms. The authors compare ...

* This paper is a condensation of 4-D/RCS: A Reference Model Architecture for Demo III, NISTIR 5994, March 1997 ABSTRACT 4-D/RCS is a reference model architecture that integrates the NIST (National Institute of Standards and Technology) RCS Real-time Control System [Albus & Meystel],with the German (Universitat der Bundeswehr Munchen) VaMoRs 4D approach to dynamic machine vision [Dickmanns]. 4-...

UNLABELLED Reactive chlorine species (RCS) defense mechanisms are important for bacterial fitness in diverse environments. In addition to the anthropogenic use of RCS in the form of bleach, these compounds are also produced naturally through photochemical reactions of natural organic matter and in vivo by the mammalian immune system in response to invading microorganisms. To gain insight into b...
