1. Abstract Solving large-scale inverse problems in structural design, damage identification, and sensor layout using multi-objective genetic algorithm optimization methods requires the use of advanced representations. The implicit redundant representation (IRR) provides a flexible encoding that has shown significant benefits in solving inverse problems in which the solution involves determinin...

in recent years, design of small aircrafts are studied and extensively developed. one of the most important of these aircrafts is micro aerial vehicles (mavs). as part of aerodynamic design of mavs, the wing design is important. in fact, the main part of this design is to find an appropriate shape for the wing. in this work, influence of the wing shape at low reynolds number flow is investigate...

the solubility enhancement of poorly soluble compounds is an important task in pharmaceutical technology as it leads to better bioavailability and a more efficient application. fused dispersions (fds) of simvastatin (sim) using peo-ppo block copolymer were prepared which paved the way for the formation of an amorphous product with enhanced dissolution and bioavailability. the accumulative solub...

Torsion mechanical waves have the capability to characterize shear stiffness moduli of soft tissue. Under this hypothesis, a computational methodology is proposed to design and optimize a piezoelectrics-based transmitter and receiver to generate and measure the response of torsional ultrasonic waves. The procedure employed is divided into two steps: (i) a finite element method (FEM) is develope...

A methodology for performing optimization on 3D unstructured grids based on the Euler equations is presented. The same, low-memory-cost explicit relaxation algorithm is used to resolve the discrete equations which govern the ow, linearized direct and adjoint problems. The analysis scheme is a high resolution Local-Extremum-Diminishing (LED) type scheme which uses Roe decomposition for the dissi...

objectives : to carry out in vivo and in vitro comparative pilot study to evaluate the preciseness of a newly proposed digital dental radiography setup. this setup was based on markers placed on an external frame to eliminate the measurement errors due to incorrect geometry in relative positioning of cone, teeth and the sensor. methods : five patients with previous panoramic images were selecte...
