In this study, thermoplastic polyolefin elastomeric (TPO) nanocomposites were fabricated by friction stir processing. The effect of different pin geometries on clay dispersion and mechanical properties of the TPO nanocomposite reinforced with 3% wt nanoclay has been first investigated. The optimum pin geometry namely threaded cylindrical pin was then used to fabricate the nanocomposites contain...

The slow motion of a crack line is studied via an experiment in which sheets of paper are split into two halves in a "peel-in-nip" (PIN) geometry under a constant load, in creep. The velocity-force relation is exponential. The dynamics of the fracture line exhibits intermittency, or avalanches, which are studied using acoustic emission. The energy statistics is a power law, with the exponent be...

Researcher: Royce Fernandes Title: Investigation of Pin Fin Cooling Channels for Applications in Gas Turbines Institution: Embry-Riddle Aeronautical University Degree: Master of Science in Aerospace Engineering Year: 2016 Gas turbine blades are often cooled using internal cooling channels to prevent failure at temperatures beyond material limitations. Pin fin channels are commonly used on the t...

The Epipolar Geometry Toolbox (EGT) was realized to provide a MATLAB user with an extensible framework for the creation and visualization of multiple camera systems and easy manipulation of the geometry relating them. Functions provided, for both pin-hole and panoramic vision sensors, include camera placement and visualization, computation and estimation of epipolar geometry entities and many o...

This article presents the results of research into causes wear piston pin mounted in bosses by means a hinge joint and connecting rod small end thermocompression bond. Changes geometry pin-top surface structure, which are caused mutual influence mating surfaces variable lubrication conditions, presented. The progress scuffing as result insufficient elements or oil film breaking is demonstrated....

The line geometric model of 3-D projective geometry has the nice property that the Lie algebra sl(4) of 3-D projective transformations is isomorphic to the bivector algebra of Cl(3, 3), and line geometry is closely related to the classical screw theory for 3-D rigid-body motions. The canonical homomorphism from SL(4) to Spin(3, 3) is not satisfying because it is not surjective, and the projecti...
