background and objectives: job stress is not always caused directly by the stressful sources, but it results more from the way in which those sources are perceived. therefore, a lot of factors are effective in job stress. as such, the present study was done to predict the job stress based on spiritual intelligence and self-diffrentiation of teachers of exceptional children in the town of shahri...

This paper investigates the forming of sheet metal forming under cycling loading by considering the Bauschinger effect. Different proposed plasticity models which can handle this kind of deformation process have been reviewed in details. For instance, isotropic, kinematic and combined forms in the linear and non-linear cases including the well-known Yoshida and Chaboche's models have been studi...

Optimizing a stress model is a natural technique for drawing graphs: one seeks an embedding into Rd which best preserves the induced graph metric. Current approaches to solving the stress model for a graph with |V| nodes and |E| edges require the full all-pairs shortest paths (APSP) matrix, which takes O(|V|2 log |E|+ |V||E|) time and O(|V|2) space. We propose a novel algorithm based on a low-r...

We introduce a parametrized family of energy/stress functions useful for proximity analysis, nonlinear dimension reduction, and graph drawing. The functions are inspired by the physics intuitions of attractive and repulsive forces common in graph drawing. Their minimization generates low-dimensional configurations (embeddings, graph drawings) whose interpoint distances match input distances as ...
