Performance analysis of steady-state harmonic elastography
Physics in Medicine and Biology, 2007Shear modulus estimation can be confounded by the ill-posed nature of the inverse elasticity problem. In this paper, we report the results of experiments conducted on simulated and gelatin phantoms to investigate the effect of various parameters (i.e., regularization, spatial filtering and the subzone generation process) associated with shear modulus ...

Maximal lactate-steady-state independent of performance
Medicine & Science in Sports & Exercise, 2000The maximal lactate steady state (MLSS) corresponds to the highest workload that can be maintained over time without a continual blood lactate accumulation. MLSS and MLSS intensity have been speculated to depend on performance. Experimental proof of this hypothesis is missing.33 male subjects (age: 23.7 +/- 5.5 yr, height: 181.2 +/- 5.3 cm, body mass ...

Steady-State Performance of Spline Adaptive Filters
IEEE Transactions on Signal Processing, 2016Recently, a novel class of nonlinear adaptive filters, called spline adaptive filters (SAFs), has been introduced and demonstrated to be very effective in many practical applications. The learning rules of these architectures are based on the least mean square (LMS) algorithm.

Performance Testing: Far from Steady State
2010 IEEE 34th Annual Computer Software and Applications Conference Workshops, 2010The dot com era ushered in a number of industry standard load testing tools. While there is no doubt that these tools have helped improve the quality of IT systems, performance testing in the IT industry is far from steady state. There are still severe gaps between performance test results and production systems performance in IT projects.

Steady-state performance of PWM inverter drives
IEE Proceedings B Electric Power Applications, 1983It is predicted that, with the increasing availability of digital computing facilities, computer-aided design will play an increasingly important and cost-effective role in the design of variable-speed drives (VSD). This paper describes the detailed development of an extremely versatile PWM VSD package which has the potential for investigating a wide ...

Transient and Steady-State Performance of Potential Devices
Transactions of the American Institute of Electrical Engineers, 1940THE increasing use of high-speed relaying with the resulting emphasis on the transient performance of potential devices has led to an extensive analysis of their performance under transient conditions. Both analytical and network-calculator methods have been developed for predetermining transient performance.

Parameters affecting steady-state floc blanket performance
Journal of Water Supply: Research and Technology-Aqua, 2010A laboratory-scale reactor was used to simulate a water treatment process sequence of rapid mix, hydraulic flocculation, upflow clarification with a floc blanket, and lamellar sedimentation to accomplish removal of colloidal particles. This study focused on variables affecting performance of the floc blanket including: provision of hydraulic ...

Steady-state performance of hyperslab projection algorithm
2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008This paper presents an analysis of the steady-state mean-square error of an adaptive filtering algorithm using the metric projection onto a closed hyperslab, which we refer to as the hyperslab projection algorithm (HSPA). HSPA is not only a generalization of both the normalized least mean square (NLMS) algorithm and the set-membership NLMS (SM-NLMS ...

Steady-State Performance of Reluctance Machines
IEEE Transactions on Power Apparatus and Systems, 1971Polyphase reluctance machine performance is analyzed by direct-and quadrature-axis components, by circle diagrams, and by machine admittance. Specific equations are deduced for pull-out out torque, maximum power factor, no-load current, and pull-out current.

Induction-motor steady-state performance prediction
2000Abstract The cage induction motor is used in a wide variety of applications ranging from large industrial drives to small motors in the white-goods market. This is a consequence of its simple construction, making it robust and requiring little maintenance.
