Despeckle filtering for multiscale amplitude-modulation frequency-modulation (AM-FM) texture analysis of ultrasound images of the intima-media complex
(Hindawi Publishing Corporation, 2014-03-09)
The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of cardiovascular disease (CVD). Typically, the IMT grows with age and this is used as a sign of increased risk of ...

Free vibration of single and sandwich laminated composite plates by using a simplified FSDT
(Elsevier, 2015-11)
This paper presents a simplified first order shear deformation theory (FSDT) for laminated composite and sandwich plates. Unlike the existing FSDT, the present one has a novel displacement field which include undetermined ...

Universal relation with regime transition for sediment transport in fine-grained rivers
(National Academy of Sciences, 2019-12-18)
Fine-grained sediment (grain size under 2,000 μm) builds floodplains and deltas, and shapes the coastlines where much of humanity lives. However, a universal, physically based predictor of sediment flux for fine-grained ...

Assessment of Ichu fibers as non-expensive thermal insulation system for the Andean regions
(Elsevier, 2015-12-01)
In the Andean regions, low temperatures (5 to −25 °C) combined with the wind effect give the sensation of extreme cold. Besides, in the rural areas, dwelling structures are very rudimentary, being based on adobe walls and ...

Micompr: An r package for multivariate independent comparison of observations
(The R Foundation for Statistical Computing, 2016-11-21)
The R package micompr implements a procedure for assessing if two or more multivariate samples are drawn from the same distribution. The procedure uses principal component analysis to convert multivariate observations into ...

2D amplitude-modulation frequency-modulation - based method for motion estimation
(Institute of Electrical and Electronics Engineers, 2015-02)
We present a new approach to compute the motion estimation in digital videos using 2D amplitude-modulation frequency-modulation (AM-FM) methods. The optical flow vectors are computed using an iteratively reweighted norm ...

Hardware implementation of a FPGA-based universal link for LVDS communications
(Institute of Electrical and Electronics Engineers, 2015-02-27)
We present the first hardware implementation for a FPGA-based universal link for the transmission of different low-voltage differential signaling (LVDS) connections through a single LVDS connection between different devices. ...
