In the field of free-form machining, CAM software offers various modes of tool-path generation, depending on the geometry of the surface to be machined. Manufactured surface quality results from the choice of machining strategy and machining parameters. The objective of this paper is to provide a 3D surface roughness parameter that formalizes the relative influence of both machining parameters ...

Image matching is a stage one performs as soon as one has two images of the same scene, taken from two different points of view. Matching these images aims at finding the mathematical transformation that enables passing from any point of the first one to the corresponding point in the other. As this study is related to satellite images, we show that the geometrical transformation can be approxi...

OBJECTIVE To investigate whether strength of social feedback, i.e. other people who concur (or do not concur) with one's own answer to a question, influences the way one answers health questions. METHODS Online prospective study. Two hundred and twenty-seven undergraduate students were recruited to use an online search engine to answer six health questions. Subjects recorded their pre- and po...

Whether or not steady-state topography and denudation are probable states depends on the timescale of system response to tectonic and climatic perturbations relative to the frequency of those perturbations. This paper presents analytical derivations of algebraic relations for the response time of detachment-limited fluvial bedrock channel systems both to tectonic and climatic perturbations. Det...

Cancer is a disease regulated by the underlying gene networks. The emergence of normal and cancer states as well as the transformation between them can be thought of as a result of the gene network interactions and associated changes. We developed a global potential landscape and path framework to quantify cancer and associated processes. We constructed a cancer gene regulatory network based on...

Macrophages are the initial biologic responders to biomaterials. These highly plastic immune sentinels control and modulate responses to materials, foreign or natural. The responses may vary from immune stimulatory to immune suppressive. Several parameters have been identified that influence macrophage response to biomaterials, specifically size, geometry, surface topography, hydrophobicity, su...

It is well known that in a neutrally-stratified turbulent flow in a deep constantstress layer above a flat surface, the variation of the mean velocity with respect to the distance from the surface obeys the logarithmic law (the so-called “law-ofthe-wall”). More recently, the same logarithmic law has been found also in the presence of non flat surfaces. It governs the dynamics of the mean veloci...

With the help of analytical expression vertical gravity gradient (VGG) generated by a rectangular prism, an algorithm for predicting seafloor topography using VGG data has been studied. Nevertheless, ship sounding are essential constraint in solving topography. This paper combines with anomaly to predict The main research contents include following: Using soundings and study area, observation e...

Purpose. To compare optic disc topography performed by confocal laser ophthalmoscopy in eyes with nonarteritic anterior ischemic optic neuropathy (NAION), arteritic anterior ischemic optic neuropathy (AAION), and open-angle glaucoma (OAG), adjusting for the amount of retinal ganglion cell (RGC) loss, as measured by nerve fiber layer (NFL) thickness and average visual field loss. Methods. At fou...

Methods This is a prospective, randomized, and double blind study. 17 in-patient adolescents with idiopathic scoliosis treated with DoboMed (DM) were studied for trunk morphology (surface topography – ATR, Hump Sum, absolute rotation, total rotation, POTSI and clinical examination – ATR by scoliometer, kyphosis and lordosis by plurimeter). Measurements were taken in the morning, before (first s...
