Allan Variance: Also known as short‐term stability, this is the measure of oscillator stability in the time domain. Commonly referred to as the Allan variance, it measures the RMS change in successive frequency measurements for short gate times (milliseconds to seconds) and is important in timing applications. It typically improves as the gate time increases until it becomes a measure of the me...

High-performance oscillators, atomic clocks for instance, are important in modern industries, finance and scientific research. In this paper, the authors study the estimation and prediction of long-term stability based on convex optimization techniques and compressive sensing. To take frequency drift into account, its influence on Allan and modified Allan variances is formulated. Meanwhile, exp...

The main result of [Barr (1967)] is that the cohomology of an algebra with respect to the free associate algebra cotriple can be described by the resolution given by U. Shukla in [Shukla (1961)]. That looks like a composite resolution; first an algebra is resolved by means of free modules (over the ground ring) and then this resolution is given the structure of a DG-algebra and resolved by the ...

This study tested the hypotheses that all major joints along the longitudinal axis of the body are equally active during quiet standing and that their motions are coordinated to stabilize the spatial positions of the center of mass (CM) and head. Analyses of the effect of joint configuration variance on the stability of the CM and head positions were performed using the uncontrolled manifold (U...

in order to study the seed yield stability of oilseed rape lines, a series of experiments were carried out at karaj, kermanshah, tabriz, hamedan and arak agricultural experiment stations using 10 lines, two control varieties of winter rapeseed and 3 promising lines (a total of 15 genotypes) in randomized complete block designs with three replications for two cropping seasons (2009-11). analysis...

⎯We consider the problem of scheduling a set of simultaneously available jobs on a single machine. The objective is to determine a schedule that minimizes the class-based completion time variance (CB-CTV) of the jobs while reducing the overall CTV is taken as the secondary objective. This non-regular performance measure is closely related to service stability and of practical significance in ma...

Feature selection plays an important role in knowledge discovery from many application domains with high-dimensional data. Many feature selection algorithms have been developed and shown successful at improving predictive accuracy of learning models while reducing feature space dimensionality and model complexity. Besides high accuracy, the stability of feature selection the insensitivity of th...
