Electromagnetic shields are designed to optimize the performance for shielding effectiveness and reflectivity. Multilayered laminates of different materials are developed to achieve excellent results in terms of not only in shielding effectiveness but also for reflectivity. In this paper, a three layered laminate is considered for estimation of the required parameters in the X-band frequency ra...

This article describes treatment of a young adult patient with porcelain laminate veneers for restoring unaesthetic maxillary anterior teeth with two retained primary canines. The patient had experienced an approximately two-year orthodontic treatment and had received both fixed and removable retainers for the upper arch. The patient could not afford implant supported restorations for his missi...

This paper investigates the high strain rate response of polymer matrix sandwich composites utilizing foam-filled honeycomb cores by means of a small mass impact. The reinforcement fiber chosen for use in this paper is a simple weave carbon fiber. This paper also investigates the effects of utilizing different laminate configurations in conjunction with investigation of the effectiveness of suc...

The potential use of carbon fibre laminate composites is limited by the weak out-ofplane properties, especially delamination resistance. The effect of incorporating titanium carbide to the mesophase pitch matrix precursor of carbon fibre laminate composites on interlaminar shear strength is studied both on carbonised and graphitised composites. The presence of titanium carbide modifies the opti...

Abstract. We give results for the approximation of a laminate with varying volume fractions for multi-well energy minimization problems modeling martensitic crystals that can undergo either an orthorhombic to monoclinic or a cubic to tetragonal transformation. We construct energy minimizing sequences of deformations which satisfy the corresponding boundary condition, and we establish a series o...

Dimension reduction techniques are widely used for the analysis and visualization of complex sets of data. This paper compares two recently published methods for nonlinear projection: Isomap and Curvilinear Distance Analysis (CDA). Contrarily to the traditional linear PCA, these methods work like multidimensional scaling, by reproducing in the projection space the pairwise distances measured in...

the objective of this experimental work was to assess the drop impact damage onwoven glass fibre reinforced polymer composite laminate through online method and offlinemethod. online monitoring of drop impact damage was carried out by acoustic emission (ae)technique and ae signals during the drop impact test were captured. from the analysis of aesignals, it was observed that as the impact energ...

Comparative maturation rates of 36 below-knee postoperative, healed amputation residual limbs were observed. Measured were the limb volumes and circumferences. Three methods of residual limb stabilization were employed: 1) elastic wrap; 2) plaster cast and pylon; and, 3) plastic laminate socket and pylon. The limbs receiving the plastic laminate showed the most rapid stabilization, while the el...
