The traditional method used to estimate the hydrodynamic performance of a ship uses either model test results or one many empirical methods and observe trend in fouling friction coefficient (ΔCF) over time. biggest weakness this is that as well here sometimes not well-fitted for full-scale due several reasons like scale effects and, therefore, may result an inaccurate prediction. Moreover, case...

A set of hydrodynamic equations modeling strong ionization in semiconductors is formally derived from a kinetic framework. To that purpose, a system of Boltzmann transport equations governing the distribution functions of conduction electrons and holes is considered. The charge carriers obey a degenerate gas statistics and their kinetic energy relations are arbitrary. The umklapp collisions are...

Control of Underwater vehicle manipulator systems (UVMS) are limited to human intervened tele operation in almost all practical applications. Extending these missions to autonomous or semi autonomous operation requires accurate dynamic modeling of the system. Such modeling assists system design and controller testing of autonomous UVMS. The study performs a dynamic analysis to capture relative ...

Rapid expansion of supercritical solution (RESS) is a promising technique for microparticle production. The literature points out that the RESS technique can be applied to process a wide range of materials including ceramics, polymers, biopolymers, pharmaceutics, and organic compounds. In order to achieve an adequate understanding of the RESS process, it is necessary to conduct more comprehensi...
