For a comprehensive study of Sheet Moulding Compound (SMC) surfaces, topographical data obtained by a contact-free optical method (chromatic aberration confocal imaging) were systematically acquired to characterise these surfaces with regard to their statistical, functional and volumetrical properties. Optimal sampling conditions (cut-off length and resolution) were obtained by a topographical-...

Modelling and simulation of injection moulding process is an important technique that could shorten production cycle time with improved productivity for defect-free parts. This technique is more suitable for micro-injection moulding (μIM) process as likely defects during production can be predicted. Therefore, this study aims to investigate the effect of runner dimensions on quality of moulded ...

With an ultrasonic frequency of 15 kHz and 850 W power capacity, the effects nanosilica particle inclusion on tensile, flexural, impact properties woven fiber-reinforced kenaf/carbon fiber/epoxy hybrid composites were explored experimentally. The nanoparticles dispersed uniformly in epoxy using probe. Test samples made according to ASTM requirements for three distinct weight compositions partic...

I propose to create a framework for separating foreground information from background in computer displays by constructing “relevancy masks.” By using various sources of structural information, I will be able to determine how likely it is that any given pixel on a screen is part of the foreground (the essential information) of the display. These masks can be used for a variety of applications, ...

The fractal image compression problem put forward three major requirements: speeding up the compression algorithm, improving image quality or increasing compression ratio. Major variants of the standard algorithm were proposed to speed up computation time. But most of them lead to a bad image quality, or a lower compression ratio. In this paper we present an implementation based on genetic algo...

between 1371 to 1379, of 10 patients with radial tunnel syndrome, 9 patients were treated by decompression of the posterior interosseous nerve. 8 patients were followed up more than 10 months. one patient improved without surgery. half of the patients suffered from pain and all of them had variable degrees of paralysis in muscles innervated by deep branch of the radial nerve. the syndrome was d...

The field of image set compression, which refers to the compression of image sets like photo albums and medical images, is becoming increasingly relevant in today’s digital world. In recent years, several schemes for image set compression have been proposed. In this paper, we propose a new SURF based image set compression scheme which uses SURF and HEVC. We also provide comparison results of ou...

percutaneous vertebroplasty is a promising therapeutic technique for pain control in patients with pathologic fractures of vertebral bodies. percutaneous vertebroplasty is an appropriate treatment for vertebral pathologic fractures, which is resistant to other usual treatment. it is a useful and only choice in special cases, because of less tissue damage and there is no risk of open surgery and...

Zirconia-toughened alumina (ZTA) using yttria-stabilised zirconia is a good option for ceramic-ceramic bearing couples for hip joint replacement. Gelcasting is a colloidal processing technique capable of producing complex products with a range of dimensions and materials by a relatively low-cost production process. Using gelcasting, ZTA samples were prepared, optimising the stages of fabricatio...
