phytoplanktons are the first bio- indicators of pollution in aquatic ecosystems. phytoplankton assemblage and aquatic ecosystems are always influenced by environmental factors therefore these environmental changes and threats must be understood in any ecosystem. phytoplankton are inexpensive and readily available bio- indicators. in the present study, phytoplankton were used to study the sefid ...

the purpose of this study is to determine the relationship between employees’ perception of authentic leadership and their promotive psychological ownership and preventive psychological ownership. for this purpose, the survey-analytical method of research was used. population of this research consists of line staff of iran insurance company in tehran. a sample of 129 employees was selected rand...

EIT waveforms have components synchronous with cardiac activity, which are often assumed to originate from the blood perfusion. There are numerous other contributions to this signal. The goal of this paper is to provide a list of the factors which could be at the origin of these cardiacrelated components, to help guide future research.

In this paper, a new frequency-based approach to motion segmentation is presented. The proposed technique represents the sequence as a spatio-temporal volume, where a moving object corresponds to a three-dimensional object. In order to detect the “3D volumes” corresponding to significant motions, a new scheme based on a band-pass filtering with a set of logGabor spatio-temporal filters is used....

The effect a perturbing field has on an electromagnetically induced transparency within a three-level system is presented. The perturbing field is applied resonant between one of the lower levels of the system and a fourth level. The electromagnetically induced transparency feature is split and this is measured experimentally for both single and bichromatic driving fields. In the single-driving...

In bilateral teleoperation, the operator holds a local robot which determines the motion of a remote robot and continuously receives delayed force feedback. Transparency is a measure of teleoperation system fidelity. The ideal teleoperator system is the identity channel, in which there is neither delay nor distortion. During the last decades transparency was widely analyzed using two-port hybri...

Abstract Automated algorithms are silently making crucial decisions about our lives, but most of the time we have little understanding how they work. To counter this hidden influence, there been increasing calls for algorithmic transparency. Much ink has spilled over informational account transparency—about much information should be revealed inner workings an algorithm. But few studies questio...

Neutrosophy is a new branch of philosophy that studies the origin, nature, and scope of neutralities, as well as their interactions with different ideational spectra. Aim of this article is to find the maximum and minimum solution of the fuzzy neutrosophic soft relational equations xA=b and Ax=b, where x and b are fuzzy neutrosophic soft vector and A is a fuzzy neutrosophic soft matrix. Wheneve...
