Reconstruction of severe composite defects of the face is challenging for reconstructive surgeons. Despite several reconstructive techniques, the functional and aesthetic results of these patients are not acceptable. As a major organ, face, has an utmost importance in daily life. The specific characteristics of face require not a reconstruction, but a replace with same tissue. With the evolutio...
A sequence stratigraphic study of terrigenous and carbonate rocks of the Infra Krol Formation and Krol Group in the Lesser Himalaya fold and thrust belt of northern India was undertaken as part of a broader investigation of the significance of carbon isotope data in Neoproterozoic successions. Eight regional stratigraphic discontinuities were traced over a distance of nearly 300 km, and interpr...
In this research, the mechanism of joining three sheets of metals, i.e. brass-steel-brass, by cold roll welding process has been studied. For this purpose, the two surfaces of steel sheets were roughened with stainless steel wire brush by different amounts, then the brass sheets were put on both sides of the steel sheets, before they were subjected to cold roll process. During rolling, peaks of...
Face detection and recognition have wide applications in robot vision and intelligent surveillance. However, face identification at a distance is very challenging because long‐distance images are often degraded by low resolution, blurring and noise. This paper introduces a person‐specific face detection method that uses a nonlinear optimum composite filter an...
Lignin is a valuable biomaterial. It is both naturally abundant and readily available as a byproduct of the pulping processes, and the proper reprocessing of lignin is an effective way to achieve waste recovery. Lignin fiber mats with web structures can be produced using electrospinning techniques. Such fiber mats are a promising material for use in the production of filter products. This study...
The present study aimed to investigate whether human body forms--like human faces--undergo holistic processing. Evidence for holistic face processing comes from the face composite effect: two identical top halves of a face are perceived as being different if they are presented with different bottom parts. This effect disappears if both bottom halves are shifted laterally (misaligned) or if the ...
This paper presents comprehensive experimental and numerical studies on the face-on and edge-on impact behavior of composite laminates. Experimental work is focused on finding the impact energy limits for barely visible impact damage (BVID) when a laminated composite plate is impacted either on its face or an edge. High-fidelity finite element analysis (FEA) model utilizing Enhanced Schapery th...
This study investigates the flatwise compressive performance of developed sandwiches with core stitching modification. Polyvinyl chloride (PVC) foam cores a density 0.048 g/cm3 were stitched 600-tex glass fiber yarns. Then materials sandwiched carbon/epoxy and glass/epoxy face sheets, respectively. The composite sandwich structures produced by applying vacuum bag method, layers co-cured. non-st...
Abstract Polymer sandwich structures have high bending stiffness and strength also low weight. Therefore, they are widely used in the transportation industry. In conceptual design phase, it is essential to a method model mechanical behavior of its adhesive joints accurately full-vehicle scale investigate different structure partitioning strategies. this paper, novel approach using finite elemen...
Meditative mindfulness practices, promoting sustained attention and reducing mind-wandering, have been associated with improvements in cognitive abilities memory. The present study explored whether a non-meditative practice could be successfully applied forensic application; specifically, instructions can embedded the face-composite construction process to facilitate identification. Twenty part...
