TL;DR: This paper proposes convex estimators specifically for the RSS-based localization problems and applies the semidefinite relaxation technique to the derived nonconvex estimator, which improves the estimation performance.

TL;DR: In this article, a model-based technique for the detection and diagnosis of gear faults was proposed based on the signal averaging technique, the proposed technique first establishes an autoregressive (AR) model on the vibration signal of the gear of interest in its healthy state.

TL;DR: In this paper, it is shown that the stress dependence of the thermoelastic constant can be explained by the temperature dependence of elastic properties of the material, and excellent agreement between the theoretical predictions and experimental data is achieved.

TL;DR: In this article, a revised theory of the thermoelastic effect was presented which offers an explanation of the mean stress dependence of the thermodynamic constant, and further experimental results were presented to validate this theory, and to demonstrate that the predicted higher harmonic thermal response of a body under a single frequency excitation is indeed observable.

Abstract: This invention relates to a method and apparatus for transmitting constant and variable bit rate traffic in a broadband ISDN switch. Data from constant bit rate sources such as television cameras is entered into a group of queues. Each member of the group for queuing data of a different band of bit rates. Data is transmitted from these queues with highest priority from the queue storing data of the highest band of bit rates. If the longest enqueued entity of data in one of the other queues has been enqueued for more than a prespecified period, its priority is increased. Analytic studies have shown that use of three queues for constant bit rate traffic and a fourth queue for variable bit rate traffic allows a high occupancy in the output channels to be maintained with a negligible number of data entities excessively delayed.
