Highly Accurate Timestamping for Ethernet‐Based Clock Synchronization
Journal of Computer Networks and Communications, Volume 2012, Issue 1, 2012., 2012 It is not only for test and measurement of great importance to synchronize clocks of networked devices to timely coordinate data acquisition. In this context the seek for high accuracy in Ethernet‐based clock synchronization has been significantly supported by enhancements to the Network Time Protocol (NTP) and the introduction of the Precision Time ...

Current Gerontology and Geriatrics Research, Volume 2012, Issue 1, 2012., 2012 Background. Recurrent falls are common among the aged. Vision is needed in maintaining balance, and impaired vision may be an intrinsic risk factor of recurrent falls. The aim was to perform a systematic review about the relationships between eye diseases or impaired vision and the risk of recurrent falls in the aged. Material and Methods.

Advances in Operations Research, Volume 2011, Issue 1, 2011., 2011 This paper focuses on real‐time nonpreemptive multiprocessor scheduling with precedence and strict periodicity constraints. Since this problem is NP‐hard, there exist several approaches to resolve it. In addition, because of periodicity constraints our problem stands for a decision problem which consists in determining if, a solution exists or not ...

Mode‐Locking, Quasi‐Period and Chaos of Rotors Mounted on Nonlinear Bearings
International Journal of Rotating Machinery, Volume 6, Issue 3, Page 191-200, 2000., 2000 This study is to investigate the dynamics of a rotor, with a single degree of freedom (SDOF), mounted on nonlinear bearings. This system has piecewise‐linear stiffness and is subjected to a forcing excitation due to residual mass imbalance as well as a parametric one due to an axial periodic thrust.

S‐J‐Ideals: A Study in Commutative and Noncommutative Rings
Journal of Mathematics, Volume 2024, Issue 1, 2024.In this paper, we introduce the concept of S‐J‐ideals in both commutative and noncommutative rings. For a commutative ring R and a multiplicatively closed subset S, we show that many properties of J‐ideals apply to S‐J‐ideals and examine their characteristics in various ring constructions, such as homomorphic image rings, quotient rings, cartesian ...
