in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...

This paper considers the development of reduced chemistry models for high enthalpy and plasma flows using Principal Component Analysis (PCA) based methods. Starting from detailed chemistry models, such as multi-temperature and collisional-radiative formulations, a reduction of the variable set (species mass fractions and temperatures) is proposed by projecting the full set on a reduced basis ma...
Fatemeh Karimi Tabar was born in Asadabad/Hamedan (Iran) in 1986. She completed her B.Sc. in chemistry in 2008 from Bu-Ali Sina University, Hamedan, Iran. She was graduated from M.Sc. degree in organic chemistry from Shiraz University 2010, Shiraz, Iran. She is currently Organic Chemistry Ph.D student under the supervision of prof.

Solar sailing is a proposed means of space propulsion in which a reflective surface collects momentum from solar photons to accelerate a vehicle. The current trend within the solar sailing community is to increase sail size as solar sailing technologies advance, allowing for larger payloads and higher accelerations. However, with the miniaturization of modern payloads, sail sizes can be dramati...
This paper investigates a class of Lagrangian control systems with n degrees-offreedom (DOF) and n − 1 actuators, assuming that n − 1 virtual holonomic constraints have been enforced via feedback, and a basic regularity condition holds. The reduced dynamics of such systems are described by a second-order unforced differential equation. We present necessary and sufficient conditions under which ...
There are methods to increase fertilizer nitrogen use efficiency through optical sensor-based nitrogen application; however, the sensors are expensive and cost prohibitive to farmers in the developing world. This study evaluated a novel, reduced cost, prototype, and optical sensor to determine if it could be used with the same level of accuracy as a commercial sensor. The stability of the proto...
