چکیده

Base-catalyzed condensation of dicyclopentadienylmethane with a dipyrrylmethane dialdehyde gave a dicarbachlorin with an internal CH2 group. This unusual porphyrinoid retained highly diatropic characteristics and exhibited a porphyrin-like UV-vis spectrum.

Dynamics of Space Free-Flying Robots with Flexible Appendages

A Space Free-Flying Robot (SFFR) includes an actuated base equipped with one or more manipulators to perform on-orbit missions. Distinct from fixed-based manipulators, the spacecraft (base) of a SFFR responds to dynamic reaction forces due to manipulator motions. In order to control such a system, it is essential to consider the dynamic coupling between the manipulators and the base. Explicit d...

Heat Transfer Enhancement of Al2O3–H2O Nanofluid Free Convection in Two-Phase Flow with Internal Heat Generation Using Two Dimensional Lattice Boltzmann Method

A two-phase lattice Boltzmann model considering the interaction forces of nanofluid has been developed in this paper. It is applied to investigate the flow and natural convection heat transfer of Al2O3–H2O nanofluid in an enclosure containing internal heat generation. To understand the heat transfer enhancement mechanism of the nanofluid flow from the particle level, the lattice Boltzmann metho...

Queueing Inventory System in a Two-level Supply Chain with One-for-One Ordering Policy

Consider a two-level inventory system consisting of one supplier and one retailer. The retailer faces a Poisson demand with a known rate and applies base stock (one-for-one ordering) policy. That is, his inventory position is set to a pre-determined level, so the demand pattern is transferred exactly to the supplier. The supplier has an inventory system and a service unit with exponentially dis...
