A new method of segmentation of ultrasound Carotid Artery (CA) has been proposed. Atherosclerosis is the thickening and narrowing of the arteries due to formation of plaque on the walls of the artery. It is one of the major causes of stroke.Intima-media thickness (IMT) is now being considered as an indicator of atherosclerosis. CA segmentation is based on the improvised snake’s initialization m...

This study presents the variations of photoplethysmogram (PPG) morphology with age. PPG measurement is done noninvasively at the index finger on both right and left hands for a sample of erectile dysfunction (ED) subjects. Some parameters are derived from the analysis of PPG contour showed in association with age. The age is found to be an important factor that affects the contour of PPG signal...

CONCLUSION The study shows that there are differences in the measurement of the action potentials with and without the stylet in the Nucleus Freedom Contour Advance that are higher in the apex than in the base of the cochlea. OBJECTIVES To determine if there are differences in the intraoperative impedances and in the neural response telemetry threshold values in the Nucleus Freedom Contour Ad...

For several decades, it becomes possible to delineate waterbodies and their dynamics from optical or radar images, that are now available at high spatial temporal resolutions. We present here an interpolation approach takes benefits this delineation in endorheic areas. It consists computing isovalue contour lines improve topography estimates classically obtained measurement points only. The app...

BACKGROUND Electromagnetic stimulation of the nervous system has the advantage of reduced discomfort in activating nerves. For brain structures stimulation, it has become a clinically accepted modality. Coil designs usually consider factors such as optimization of induced power, focussing, field shape etc. In this study we are attempting to find the effect of the coil contour shape on the elect...

Measurement path planning plays an essential role in on-machine measurement, which is often required to be time-saving and collision-free. This paper proposes a novel methodology develops automatic collision avoidance strategy for measurement. points are generated by Contour section sampling (CSS), Grid mesh (GMS), Locally dense (LDS) on the free-form surface. Afterwards, shortest algorithm (SP...

Contour Crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The Contour Crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for Contour Crafting benefit the technology by increasin...

The introduction of disulfide bonds into proteins creates additional mechanical barriers and limits the unfolded contour length (i.e., the maximal extension) measured by single-molecule force spectroscopy. Here, we engineer single disulfide bonds into four different locations of the human cardiac titin module (I27) to control the contour length while keeping the distance to the transition state...
