The main goal of this study was to exemaine the effect of inquiry-based learning method on achivement emotions of elementary students. The study had a quasi experimental design with pre-test, post-test and control group. The research population was included all of the fifth grade male students of the elementary schools in sanandaj during the acacdemic year of 2016-17, witch among them a fifth ...
This article briefly reviews the history of coronavirus detection and states structural characteristics pathogenesis SARS-CoV-2 strain. Following conclusion that cellular senescence is thought to contribute susceptibility, this continues review structure function telomeres. Finally, it link between COVID-19 telomeres caused by
Multiple-shot person re-identification deals with the problem to build the correspondence between the images of the same person appearing at different sites captured by onsite deployed cameras. The difficulty stems from large within-class but small betweenclass variations caused by the change of person appearance and environment. Traditional methods on feature/signature design and/or distance/d...
The behavior of the “constants”, G, c, h̄, a, e, mi and Λ, considering them as variable, in the framework of a flat cosmological model with FRW symmetries described by a bulk viscous fluid and considering mechanisms of adiabatic matter creation are investigated. Two cases are studied; one with radiation predominance and another of matter predominance. It is found that with the solution obtained ...
To classify time series by nearest neighbors, we need to specify or learn one or several distance measures. We consider variations of the Mahalanobis distance measures which rely on the inverse covariance matrix of the data. Unfortunately — for time series data — the covariance matrix has often low rank. To alleviate this problem we can either use a pseudoinverse, covariance shrinking or limit ...
