This paper aims to present a survey of object recognition/classification methods based on image moments. We review various types of moments (geometric moments, complex moments) and moment-based invariants with respect to various image degradations and distortions (rotation, scaling, affine transform, image blurring, etc.) which can be used as shape descriptors for classification. We explain a g...

We characterized the extent to which body mass influences the relationship between hip joint moments during locomotion and bone mineral density (BMD) of the proximal femur in healthy young women (n = 24). There is some evidence of a direct relationship between hip joint moments during locomotion and BMD of the proximal femur in patients with osteoarthritis. Nevertheless, based on expected simul...

This paper presents the horizontal bearing characteristics of piles in coral sand and silica from comparative experimental studies. Six model with different diameters were tested. The capacity, deformation characteristic, bending moment, p–y curve, change soil pressure, as well particle breakage behaviour investigated. results show that, foundation, capacities increments pressures are obviously...

The use of empirically calibrated moment-rotation models that account for strength and stiffness deterioration of steel frame members is paramount in evaluating the performance of steel structures prone to collapse under seismic loading. These deterioration models are typically used as zero-length springs in a concentrated plasticity formulation; however, a calibration procedure is required whe...

Purpose: Due to the paucity of the information regarding the lower limb biomechanics in slow speeds running as well as  concentration of the majority of previous studies in a single movement plane, aim of the present study was investigation on a kinetic based analysis of lower limb’ joints with increasing running speed. Methods: 28 runners asked to stay on the belt speed of treadmill that was ...

For polycrystalline NiFe/FeMn bilayers, we have observed and quantified the rotation of the pinning direction in the exchange bias training and recovery effects. During consecutive hysteresis loops, the rotation of the pinning direction strongly depends on the magnetization reversal mechanism of the ferromagnet layer. The interfacial uncompensated magnetic moment of antiferromagnetic grains may...

The study of the kinematics of globular clusters in the outer regions of the Large Magellanic Cloud by Schommer et al. [1] suggested a flat rotation curve, perhaps out to 15 kpc: the LMC might have a dark matter halo. Here, from a composite H i and star cluster rotation curve (fig. 1), I want to estimate the parameters of an isothermal halo added to a ‘maximum disk.’ Luks and Rohlfs [2], in the...

The dC$ign of reciprocating compressor cylinder heads consi.Us of thr= main tasks: 1) calculation methods to determine !he aclual SUCS$C$, 2) dctctmination of the factors of safety given thC$C stresscs, 3) validation of these SlrCSSC$ with strain gage dala. This paper will address the first of thC$C tasks, namely, the calculalion of cylinder head Stn=ssCS. A gcncnlized procedure calculating str...

Partially Encased Composite (PEC) column is one of the recent achievements in the field of composite columns. This paper presents a combined experimental and theoretical study on the mechanical performances of six octagonal PEC columns subjected to axial compressive and bending moment loading. The major different between them was the concrete reinforcement details. The parameters studied in the...
