Simultaneous Equations Models

Simultaneous Equations Models (SEM) is a statistical technique widely used in economic science to model the simultaneity relationship between variables. In the past years, this technique has also been used in other fields such as psychology or medicine. Thus, the development of new estimating methods is an important line of research. In fact, if we want to apply the SEM to medical problems with the main goal being to obtain the best approximation between the parameters of model and their estimations. This paper shows a computational study between different methods for estimating simultaneous equations models as well as a new method which allows the estimation of those parameters based on the optimization of the Bayesian Method of Moments and minimizing the Akaike Information Criteria. In addition, an entropy measure has been calculated as a parameter criteria to compare the estimation methods studied. The comparison between those methods is performed through an experimental study using randomly generated models. The experimental study compares the estimations obtained by the different methods as well as the efficiency when comparing solutions by Akaike Information Criteria and Entropy Measure. The study shows that the proposed estimation method offered better approximations and the entropy measured results more efficiently than the rest.

An experimental study was conducted by Hughes Aircraft Company to determine telescope field of view requirements for human recognition of navigation stars. The study was conducted at the Griffith Park Planetarium in Los Angeles. Four Air Force navigators viewed the night sky projected on the planetarium dome through a simulated telescope. The subjects had control of telescope azimuth and elevation. The telescope had unity power fields of view ranging between 10 and 45 degrees. The subjects were required to identify and acquire any one of the 35 major navigation stars. The results revealed a significant inverse relationship between field of view size and navigation star acquisition-identification time. Identification errors also varied inversely as a function of field of view size, and mean acquisition-identification times were significantly different between subjects. The minimum field of view required for rapid, accurate star identification-acquisition was established to be between 25 and 30 degrees.

Energy harvesting from wind in urban areas is an important solution to meet energy needs and environmental care. This study describes the effect of blade angle on the aerodynamic performance of small-scale Archimedes spiral-wind-turbine blades by computational simulation, which is experimentally validated. Archimedes wind turbine is classified as one of the HAWTs. The computational approach was used to predict the aerodynamic performance of the scaled-down rotor blades. Blade angle is defined by the angle between the rotational axis and the tip of the blade, which varied from 50° to 65° with an interval of 5°. The computational study was carried out using the ANSYS CFX 19 software for a steady incompressible flow. The performance parameters of the wind turbine, which are power and torque coefficients were explored for different blade angles. This was carried out for wind speed from 5 to 12 m/s with an interval of 1 m/s. In order to validate the results of the computational simulation, an experimental study was carried out using a scaled-down 3D-printed models. The experimental study concentrated on the effect of blade angle on the rotating speed for the different turbine models. Obviously, the results highlight that the maximum power coefficient has an inverse relation to the blade angle.
