The AASHTO code of practice for design of bridges shows that the ductility level for foundation is given equal to one. Bridges are classified in three classes. For class of essential and normal bridges a question for not to use ductility level due to the importance of bridges’ costs is become an important item in different countries particularly in Middle east. This paper aimed to study on pe...

Context: Recognition of the importance of informatics to the practice of pathology has surged. Training residents in pathology informatics has been a daunting task for most residency programs in the United States because faculty often lacks experience and training resources. Nevertheless, developing resident competence in informatics is essential for the future of pathology as a specialty. Obje...

In this study two breakwater models with different conditions of bed, waves and water level are employed to analyze the toe stability and scour depth. The tests are conducted with regular waves. It is found that the scour depth in front of the rubble-mound breakwater depends on wave height, structure slope, water level and wave period, but the results reveal the effect of wave period toe is mor...

A set of input specifications is designed to enable engineers and scientists, who may not be computer experts, to describe the finite element analysis (FEA) procedures for a new application. The input directs PIER, a code derivation/generation system being developed in Common Lisp, to produce either sequential or parallel FEA codes. The PIER input employs common terminology and notations as use...

Acoustic Daylight is a new technique for creating pictorial images of undersea objects from the acoustic illumination provided by the ambient noise field. As in conventional photography, the directionality of the illumination affects the contrast in the image through the shadows that are cast. Three aspects of the directionality, or anisotropy, of ambient noise in the ocean are discussed in thi...

Investigation of the flow pattern around bridge piers is of utmost importance because of its great effect on destruction of the piers. Despite the hydrodynamical and structural values of designing sections causing minimum turbulence against the flow passing the bridge pier, a review of the literature shows that investigation of the flow pattern around bridge piers with varying section has not b...

insurers have in the past few decades faced longevity risks - the risk that annuitants survive more than expected - and therefore need a new approach to manage this new risk. in this dissertation we survey methods that hedge longevity risks. these methods use securitization to manage risk, so using modern financial and insurance pricing models, especially wang transform and actuarial concepts, ...
