Nowadays with increasing use of numerous nonlinear loads, voltage and current harmonics in power systems are one of the most important problems power engineers encounter. Many of these nonlinear loads, because of their dynamic natures, inject time-varying harmonics into power system. Common techniques applied for harmonics measurement and assessment such as FFT have significant errors in presen...

Quantification in clinical, diagnostic electromyography (EMG) currently includes motor unit action potential (MUAP) analysis and interference pattern analysis. Early efforts to examine the frequency/power spectra of the interference pattern showed modest value but the technique was not developed further. This paper re-examines spectral analysis, extending it into the time-varying domain, which ...

In this paper, we design dynamic probabilistic caching for the scenario when instantaneous content popularity may vary with time while it is possible to predict average over a window. Based on popularity, optimal probabilities can be found, e.g., from solving optimization problems, and existing results in literature implement via static placement. The objective of work that: i) converge (in dis...

the large number of applications manages time varying data. existing databasetechnology seldom supports temporal database, tdb, according to time aspects.these intrinsic temporal database applications rely on such database which storesand retrieves time referenced data. moreover, applications need to be managed oncommon data items access simultaneously and to be precluded from inconsistencyas s...

Inspiratory motor discharges, in addition to long-time-scale rhythmic oscillatory bursting, exhibit short-time-scale rhythmic oscillations that have been identified, and subsequently characterized, using power spectral analyses [predominantly fast-Fourier transforms (FFT)]. These analyses assume that the signal being analyzed is stationary; however, this is not the case for most biological sign...

Alkyd resins were prepared into four different sets by varying the percentage concentrationof the glycerol content. Various properties such as the viscosity, Surface drying time, solubilityand color of the alkyd resins were evaluated for the various sets. The alkyd resin with the highestglycerol content was the most viscous, brownish in color and having the highest molecularweight this is due t...
