We give a geometric interpretation of the entropy of the supertubes with fixed conserved charges and angular momenta in two different approaches using the DBI action and the supermembrane theory. By counting the geometrically allowed microstates, it is shown that both the methods give consistent result on the entropy. In doing so, we make the connection to the gravity microstates clear. 1 Intro...

The purpose of the present study was to determine the relationship between cross-sectional design and fracture load using a static load bearing test in yttria-stabilized tetragonal zirconia polycrystal ceramic frameworks on a molar fixed partial denture. The test framework was designed as a 3-unit bridge with two abutment teeth at the second premolar and second molar of the mandible. The cross-...

Purpose The purpose of the study is to optimise cross-sectional shape passively cooled horizontally mounted pin-fin heat sink for higher cooling performance and lower material usage. Design/methodology/approach Multi-objective optimisation technique used design fins. Non-dominated sorting genetic algorithm (NSGA-II) combined with a geometric module develop optimiser. High-fidelity computational...

In this study, a new meta-heuristic algorithm called teaching-learning-based optimization (TLBO) is used for the size and shape optimization of structures. The TLBO algorithm is based on the effect of the influence of a teacher on the output of learners in a class. The cross-sectional areas of the bar element and the nodal coordinates of the structural system are the design variables for size a...

Aim: The purpose of this study was to quantify the usage of rubber dam (RD) among general and specialty dental practitioners during composite restorative procedures in Saudi Arabia. Materials and methods: A cross-sectional questionnaire-based study was conducted from March to April 2012 in association with Saudi Dental Society on 306 general dental practitioners (GP), dentists specialized in op...

Industrial turbomachinery design requires fast and reliable algorithms for the numerical optimization of design parameters that innuence the ow in the turbomachine. The problem considered in this paper is to determine the cross-sectional shape of a blade in a turbomachine in order to reproduce as well as possible a given velocity proole of the ow around the blade. It is formulated as a least sq...

PRINCIPLE Most of the existing 3D shape measurement systems use laser scanning[2], and requires a time (several seconds, typically) for measurement. The principle of laser scanning measurement is triangulation between camera and laser projector. In the field of computer vision, 3D shape of the target object is reconstructed from multiple images using triangulation between multiple cameras (ster...
