The Boeing X-32 is a demonstration jet designed for the Joint Strike Fighter contest. He lost the Lockheed Martin X-35 demonstrator, which was further developed in the Lockheed Martin F-35 Lightning II. Boeing's competitive advantage has been to provide considerably lower costs of production and lifecycle by minimizing variations between different versions of the JSF. Therefore, the X-32 was designed around a delta wing of the carbon fiber composite. The wing had an opening of 9.15 meters, with a current of 55 degrees on the front edge and could have up to 20,000 kilograms of fuel. The purpose of the large inclination angle was to allow the use of a thick wings section while obtaining limited transonic aerodynamic resistances and a good angle for the corresponding antenna equipment installed in the wing. Wings would be a challenge to be done. The cost competition strategy also led Boeing to choose a direct traction vectoring system for the short-term STOVL landing requirement, as this would require the addition of a traction vectoring module around the main engine. However, this choice requires the engine to be mounted directly behind the cockpit and changing the center of gravity before being ordinarily positioned in the jets of the plane (behind the plane) to allow neutral movement of the attitude. Boeing proposed in the 1960s a supersonic fighter as a gravity motor with vector pushing nozzles, but never surpassed the images published in the aviation week. By comparison, Lockheed's entry showed, if not, a smaller version of the F-22 Raptor stealth fighter. The nickname of X-32, Boeing, was "Monica. " However, another direct lifting selection effect was the chrome-air intake, similar to the Vought F-8 Crusader and LTV A-7 Corsair II. This was necessary to provide sufficient air for the main engine (to provide the force of support) during the zero speed horizon when it could not exploit the ram air pressure. A blow to the effect of this large input was the direct potential visibility of the compressor blades to the radar. Among the possibilities of attenuation were the variable moments designed to lock the received radio waves without adversely affecting the air flow.

“…It is a perfect laboratory to study the formation and evolution of rocky planets. Scientists know that Mars has low geological activity, but a Lander like InSight can reveal as long as Mars is active (Aversa et al, 2017a;and Hashim, 2009;Kwon et al, 2010;Aly and Abuelnasr, 2010;Farahani et al, 2010;Ahmed et al, 2010;Kunanoppadon, 2010;Helmy and El-Taweel, 2010;Qutbodin, 2010;Pattanasethanon, 2010;Fen et al, 2011;Thongwan et al, 2011;Theansuwan and Triratanasirichai, 2011;Tourab et al, 2011;Raptis et al, 2011;Momani et al, 2011;Ismail et al, 2011;Anizan et al, 2011;Tsolakis and Raptis, 2011;Abdullah et al, 2011;Kechiche et al, 2011;Ho et al, 2011;Rajbhandari et al, 2011;Aleksic and Lovric, 2011;Kaewnai and Wongwises, 2011;Idarwazeh, 2011;Ebrahim et al, 2012;Abdelkrim et al, 2012;Mohan et al, 2012;Abam et al, 2012;Hassan et al, 2012;Jalil and Sampe, 2013;Jaoude and El-Tawil, 2013;Ali and Shumaker, 2013;Zhao, 2013;El-Labban et al, 2013;Djalel et al, 2013;Nahas and Kozaitis, 2014).…”

InSight-Studying the 'Inner Space' of Mars. InSight, short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, is a Mars lander designed to give the Red Planet its first thorough checkup since it formed 4.5 billion years ago. It is the first outer space robotic explorer to study in-depth the "inner space" of Mars: Its crust, mantle and core. Studying Mars' interior structure answers key questions about the early formation of rocky planets in our inner solar system-Mercury, Venus, Earth and Mars-more than 4 billion years ago, as well as rocky exoplanets. InSight also measures tectonic activity and meteorite impacts on Mars today. The lander uses cutting edge instruments, to delve deep beneath the surface and seek the fingerprints of the processes that formed the terrestrial planets. It does so by measuring the planet's "vital signs": Its "pulse" (seismology), "temperature" (heat flow) and "reflexes" (precision tracking). This mission is part of NASA's Discovery Program for highly focused science missions that ask critical questions in solar system science.

“…oriented models: Object Oriented Programming (OOP) techniques are very suitable to implement the individual models of the devices, since they value the physical modeling through the definition of a small number of classes (Rumbaugh, 1991;Mota et al, 2007b;Geetha et al, 2008;Aly and Abuelnasr, 2010). The behavior of a TCD is illustrated in Fig.…”

Problem statement: During service restoration, the power level at buses can significantly differ from the one presented under steady-state conditions, demanding an amount of electric power significantly higher than the normal load. Hence, their post-outage behavior must be adequately forecasted in order to permit the development of reliable restoration plans, or to avoid inadequate actions that may lead to a subsequent shutdown of the electric power system. This problem is known in the literature as cold load pick-up and the thermostatically controlled loads can be pointed as the main responsible for this behavior. Approach: This study proposes a methodology to model the thermostatically controlled load behavior during the reenergization process, based on object oriented programming and the physical modeling of individual loads, avoiding the explicitly modeling of the electric distribution feeder. In this context, the load aggregation is also implemented using "feeder" classes in an hierarchical structure. Results: The methodology was tested considering distinct devices distributed along a hypothetical feeder and the results show the impacts of interruption duration and environmental temperature in the load behavior. Conclusion: The Cold-load phenomena can be successfully simulated based on physical parameters of thermostatically controlled loads using objectoriented programming, yielding satisfactory results. In special, the impacts of the environmental temperature in the load to be restored can be assessed in detail.
