S U M M A R Y Geometrical properties of an earthquake population can be described by summation of seismic potency tensors that provide a strain-based description of earthquake focal mechanisms. We apply this method to∼170 000 potency tensors for 0<ML ≤ 5 southern California earthquakes recorded between January 1984 and June 2003. We compare summed tensors for populations defined by faulting reg...

A coordinate independent derivation of the Eulerian and Lagrangian strain tensors of finite deformation theory is given based on the parallel propagator, the world function, and the displacement vector field as a three-point tensor. The derivation explicitly shows that the Eulerian and Lagrangian strain tensors are two-point tensors, each a function of both the spatial and material coordinates....

rndetermination of rock mass deformation modulus is very important in different projects, especially in civil and mining engineering works. in-situ measurements such as dilatometer, plate load and flat jack methods may be applied to determine the deformation modulus. however, these methods are very expensive and time- consuming. analytical methods are very useful approaches which can also be us...

This study was a qualitative research which was done by a case study approach. The samples were chosen from rural development experts of Hamedan Province during a snowball sampling process. The data were collected by the semistructured interviews. The data collection was done by faceto- face interviews, after the interview questions guide was determined. The theoretical saturation was attained ...

Objective: This article presents an application of cluster analysis for social sciences researches especially those studies that have an interview as part of their data collection. This application is more suitable for sequential mixed method researchers who use quantitative data to frame subsequent qualitative subsamples for conducting interviews.  Methods: In more detail, the algorithm (i....

Background: There has been considerable development in the clinometric of stroke. But, researcher is concerned that some scales are too generic, inherently and the insight may not be provided. The current study was conducted to determine which scale or scales should be used in stroke survivors. Methods: We selected 67 studies which published between January 2010 and December 2018 from Up to d...
