Directed energy deposition (DED) is a family of additive manufacturing technologies. With these processes, metal parts are built layer by layer, introducing dynamics that propagate in time and layer-domains, which implies additional complexity consequently, the resulting part quality hard to predict. Control deposit thickness height critical issue since it impacts on geometrical accuracy, proce...

Abstract Introduction: In this work, we use simulated data to quantify the different failure mechanisms of a previously presented low-cost jump height measurement system, based on widely available consumer smartphone technology. Methods: order assess importance preconditions algorithm, generate synthetic dataset 2000 random parabolas for randomly generated persons without real-world artifacts. ...

purpose accurate measurement or prediction of fat mass is useful in physiology, nutrition and clinical medicine. most predictive equations currently used to assess percentage of body fat or fat mass, using simple anthropometric measurements were derived from people in western societies and they may not be appropriate for individuals with other genotypic and phenotypic characteristics. we develo...

Background & Aims: Two famous methods are commonly used for the measurement of carpal height ratio. Both methods are performed on anteroposterior radiogram and have some shortcomings. We are going to introduce a new method for measuring this index in lateral view of the wrist radiogram' Methods: This cross-sectional and case-control study was conducted on 100 anteroposterior and lateral radiogr...

The comparison of SAR-derived wind speeds from scatterometer-based transfer functions and in situ or model wind speeds requires that both data sets represent the presence of equivalent atmospheric stratification and measurement height. We discuss the atmospheric surface layer dynamics underlying corrections to equivalent atmospheric stratification and measurement height. In addition, we review ...

An interference fringe modulation skewing effect in white-light vertical scanning interferometry that can produce a batwings artifact in a step height measurement is described. The skewing occurs at a position on or close to the edge of a step in the sample under measurement when the step height is less than the coherence length of the light source used. A diffraction model is used to explain t...
