Advanced Engineering Materials, EarlyView.Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Multiscale Transform Methods in Data Analysis
, 2007 : We describe the use of the wavelet transform for multivariate data analysis problems. In prediction, a multiscale transform of time-varying data can allow forecasts of each scale, followed by combining of the individual forecasts.

THE PROBLEM OF CONTOURS IN TRANSFORM IMAGE CODING [PDF]
, 2008 Object contours contribute to a large extent to the perceived quality of an image but are typically quite hard to compress. As a matter of facts, many coding algorithms fail to describe efficiently this information.

A new optimal window with a nonnegative Fourier transform [PDF]
, 1992 This paper introduces an optimal window with a nonnegative frequency response. 111e design, proposed by Dr. John W. Adams of California State University Northridge, provides the optimal compromise between peak sidelobe amplitude and total sidelobe area ...

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy
Advanced Engineering Materials, EarlyView.Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Advanced Engineering Materials, EarlyView.Binder‐free laser powder bed fusion of 8YSZ with a femtosecond laser is used to map process windows linking scan strategy, heat accumulation, and grain growth. Time‐resolved thermography and simulations reveal thermal regimes that enable continuous, vitrified, and fine‐grained 8YSZ surface layers without absorptive additives and demonstrate ...

APPLICATION OF WAVELET-TRANSFORM AND PRONY METHOD FOR THE BIOGENIC SIGNALS IDENTIFICATION
Advanced Engineering Research, 2010 Non-stationary signals of biogenic character (cardiogram, eleсtroencephalogram, etc.) are considered. Analysis of signals with the use of wavelet-transform and Prony method - which unlike classical Fourier method make an improved spectral evaluation - is

Fabrication Routes for Ionic Conducting Fiber Strain Sensors
Advanced Engineering Materials, EarlyView.Ionic conducting fiber strain sensors (ICFSs) offer compliant, textile‐integrable sensing. Thus far, the commercialization of ICFSs has been constrained by fiber fabrication routes. This review provides a fabrication‐centric analysis of ICFSs correlating processing strategies with material properties and scalability.

Studying The Effect of Window type On Power Spectrum Based On MATLAB
Tikrit Journal of Engineering Sciences, 2012 The representation that describes signal’s frequency behavior can be divided into two categories: linear representation such as the Fourier-transform and quadratic representation such as power spectrum.
