As part of a programme investigating the structural integrity of welds, the Digital Image Correlation (DIC) technique was used to obtain the full-field strain distribution during tensile testing of cross-weld specimens cut from a multi-pass girth welded pipe. The displacement maps were analyzed using Matlab scripts to compute local stress-strain variations from which the local proof stress valu...

In this study the predictability of 15 discrete emotions (e.g. fear, uncertainty, rage, anger, sadness, love, tenderness, satisfaction, joy, sexual pleasure, surprise) and 6 bipolar emotional dimensions (feeling good/bad, strong/ weak, certain/uncertain, tense/relaxed, excited/calm, sympathetic/not sympathetic) by 39 acoustic parameters was tested by multiple regression analysis. The stimulus m...

In this study, a novel approach is proposed for modeling speech parameter variations between neutral and stressed conditions and employed in a technique for stressed speech synthesis and recognition. The proposed method consists of modeling the variations in pitch contour, voiced speech duration, and average spectral structure using hidden Markov models (HMM’s). While HMM’s have traditionally b...

in order to study of the radiation interception and red to far red light ratio variations in sunflower hybrids under drought stress, nine sunflower hybrids in three separate experiments were compared as randomized complete block designs with three replications at the research station of seed and plant improvement institute in karaj in 2006. first experiment (control) was irrigated based on 60 m...

BACKGROUND Stress has been implicated as contributing to the initiation and exacerbation of bowel and discomfort symptoms in patients with irritable bowel syndrome (IBS). OBJECTIVE To examine the relationships of daily self-reported stress to gastrointestinal (GI) and psychological distress symptoms both across women and within woman in a comparison group of women without IBS and among subgro...

An algorithm for identiication of unknown parameters of nonlin-ear heat conductivity equations is proposed. Solutions of equations observed with an error are input data of the algorithm. Finite dimensional approximations of input signals and their derivatives are used. The algorithm utilizes the idea of the direct minimization of the residual of equations written in an appropriate variational f...

Pressure shear plate impact tests have revealed that when normal stress changes rapidly enough, the frictional resistance is no longer proportional to but rather evolves with slip gradually. Motivated by these findings, we focus on characterizing dynamic strength of interfaces subject rapid variations in stress. To study this problem, use laboratory experiments featuring cracks interacting a fr...

Bending analyses of isotropic, functionally graded, laminated composite, and sandwich beams are carried out using a quasi-3D polynomial shear and normal deformation theory. The most important feature of the proposed theory is that it considers the effects of transverse shear and transverse normal deformations. It accounts for parabolic variations in the strain/stress produced by transverse shea...
