This study evaluated the potential of artificial neural networks (ANNs) to predict system-level performance a thermoelectric generator (TEG), whose depends on various variables including engine load, rotation speed, and external load resistance. Therefore, Python code was developed determine an optimal ANN structure by tracking training/prediction errors as function number hidden layers nodes l...

In this paper, we first establish the Bott-type iteration formulas and some abstract precise iteration formulas of the Maslov-type index theory associated with a Lagrangian subspace for symplectic paths. As an application, we prove that there exist at least [ n 2 ] + 1 geometrically distinct brake orbits on every C compact convex symmetric hypersurface Σ in R satisfying the reversible condition...

We developed a passive haptic technique, using the brake of a DC motor, to create a greater perception of impulse force. We found that when using the brake of a DC motor, delivering two short pulses immediately prior to the main brake significantly increases the operator’s perception of impulse force. This finding was verified during our empirical assessment. In the experiment, all five partici...

Integrated vehicle dynamics control with the coordination of several vehicle subsystems is considered. The proposed algorithms of subsystem coordination based on restriction weights into the optimal control allocation allow to achieve lower energy consumption without significant impairment of stability of motion and vehicle handling compared with standard control allocation. The proposed contro...

Nitrogen oxides (NOx) contribute to a wide range of environmental effects including the formation of acid rain and destroy ozone layer. In-cylinder high temperature flame and high oxygen concentration are the parameters which affect the NOx emissions. The EGR system is a very effective way for reducing NOx emission from a diesel engine (via reduction of these parameters), particularly at the...

In this study, preheated crude sunflower oil at 75C was used in a fourcylinder, naturally aspirated, indirect injection diesel engine. The experiments were conducted at the constant engine speeds under the full load condition of the engine to determine the performance, combustion, and injection characteristics of test fuels. The engine test results have been compared with the reference values t...

A Functional Virtual Prototyping full vehicle model for a tri-axial heavy-duty truck is built, and the nonlinearity of suspension dampers and tires is also considered. With the trajectory of full vehicle gravity center, longitudinal tire force of front wheel, longitudinal acceleration, lateral acceleration, yaw rate and pitch angle as the evaluation indexes of brake property, the influences of ...

During acute angiotensin II (Ang II) infusion (200 ng/kg/min i.v.) into anesthetized rats, mean arterial pressure rose from 124±1 to 154±2 mm Hg. The peptidic Ang n antagonist saralasin lowered arterial pressure in a dose-dependent manner. The maximal decrease in pressure was similar to that observed after the Ang II infusion was discontinued. The nonpeptide Ang II antagonist, 4'-{[2-butyl-4-ch...
