Design of deformation (thermo-mechanical) processes to achieve desired structural response will be addressed. Plastic deformation is assumed to be accommodated through crystallographic slip and reorientation of crystals. Conventional methodologies towards polycrystal plasticity use an aggregate of single crystals and this choice of the aggregate affects the response of the polycrystal. In order...

The well-known thermo-elastic effect of laser irradiation can be exploited to produce strong localized stresses when an expanded, long pulse, low-intensity laser beam is used to irradiate the specimen. These stresses will produce a parametric modulation of the received ultrasonic signals, that is somewhat similar to the acousto-elastic effect often used in nonlinear ultrasonic studies. It is sh...

In this paper the optimal control of boundary heat flux in a 2-D solid body with an arbitrary shape is performed in order to achieve the desired temperature distribution at a given time interval. The boundary of the body is subdivided into a number of components. On each component a time-dependent heat flux is applied which is independent of the others. Since the thermophysical properties are t...

We study the sensitivity of algebraic eigenvalue problems associated with matrices arising from linearization and discretization of the steady-state Navier-Stokes equations. In particular, for several choices of preconditioners applied to the system of discrete equations, we derive upper bounds on perturbations of eigenvalues as functions of the viscosity and discretization mesh size. The bound...

this paper examines the relationship between accounting conservatism and informational content of earnings using data of 167 firms listed on the tehran stock exchange during 2004-2013. accounting conservatism is measured based on khan and watts' (2009) model and feltham and ohlsson (1995) price model and easton and hariss (1991) return models were used to evaluate the informational content...

Accurate in-vitro component-based diagnosis will allow clinicians to focus their efforts toward complex issues such as disease severity and reactive dose evaluation as well as establishing effective eviction measures. However to achieve this, clinical utility of component-resolved peanut allergy testing must be rigorously evaluated. In this pilot study, we compared performances of 2 component-r...

Label-free photonic biosensors fabricated on silicon-on-insulator (SOI) can provide compact size, high evanescent field strength at the silicon waveguide surface, and volume fabrication potential. However, due to the large thermo optic coefficient of water-based biosamples, the sensors are temperature-sensitive. Consequently, active temperature control is usually used. However, for low cost app...
