PURPOSE This study was to find the computed tomographic features of fibrous dysplasia of the maxillofacial region. MATERIALS AND METHODS All eight cases included in the study reported either to Government Dental College and Hospital or Nair Hospital Dental College, Mumbai between 2003 and 2009. The patients were prescribed computed tomogram in addition to conventional radiographs of maxillofa...

Abstract. Consider a nonlinearly elastic body which occupies the region Ω ⊂ Rm (m = 2, 3) in its reference state and which is held in tension under prescribed boundary displacements on ∂Ω. Let x0 ∈ Ω be any fixed point in the body. It is known from variational arguments that, for sufficiently large boundary displacements, there may exist discontinuous weak solutions of the equilibrium equations...

This research focused on developing reliability-based seismic retrofit assessment procedures for highway bridge columns. Fragility curves were developed to assess the relative performance of various retrofit methods considering several limit states. Analytical fragility curves are developed from scaled earthquake records and structural response models. A simplified, single-degree-of-freedom (SD...

The paper describes a new approach in non-circular gears design, based on the mathematical description of the meshing progress. The teeth profiles are generated by numerical integration of a differential equation, which describes the contact point displacement, along the line of action, as a function of the pitch lines shape and of the pressure angle. In the typical arrangement, a pair of non-c...

A simple model of cleavage in brittle crystals consists of a layer of material containing N atomic planes separating in accordance with an interplanar potential under the action of an opening displacement δ prescribed on the boundary of the layer. The problem addressed in this work concerns the characterization of the constrained minima of the energy EN of the layer as a function of δ as N beco...

We find the minimal weighted energy ∫ Ω a(x)∣Du∣ of maps u ∶ Ω ⊂ Rm+n → S with prescribed singularities, where a(⋅) is a continuous positive weight. Our result extends previous ones of H. Brezis, J-M. Coron and E.H. Lieb (1986), G. Alberti, S. Baldo and G. Orlandi (2003), and V. Millot (2005).
