Habitat Simulation Technique as a Powerful Tool for Instream Flow Needs Assessment and River Ecosystem Management

Instream flow needs (IFN) assessment studies are performed to provide guidelines for stream water management and to assess the impacts of different water projects such as weirs, dams and stream diversions on the available fish habitat. The physical habitat simulation is one of the IFN assessment methods and also a powerful tool in management of river ecosystem that has not become a common metho...

A Robust Control Design Technique for Discrete-Time Systems

A robust state feedback design subject to placement of the closed loop eigenvalues in a prescribed region of unit circle is presented. Quantitative measures of robustness and disturbance rejection are investigated. A stochastic optimization algorithm is used to effect trade-off between the free design parameters and to accomplish all the design criteria. A numerical example is given to illustra...

Effect of Benson’s relaxation technique on the anxiety of patients undergoing coronary angiography: A randomized control trial

Background and Purpose: Anxiety is a common problem associated with invasive medical procedures, especially in patients undergoing coronary angiography. As an intensifier at cardiovascular reactions, anxiety poses significant risk to the health of patients undergoing angiography. Researchers believe that use of Benson’s relaxation technique could reduce anxiety in different patients. Th...
