Material Requirements

To a pump manufacturer, marine cargo service represents one of the most demanding applications for which he can design and furnish equipment. In addition to being subjected to the stresses encountered in a shipboard environment, cargo pumps must often perform over a wide range of operating conditions and handle multiple fluids with different viscosities, vapor pressures, specific gravities, temperatures, and material requirements. In this paper the author reviews characteristics of the different types of pumps used for marine cargo service, with an emphasis on the special features that should be incorporated into their design for this rigorous duty. Different types of automatic self-priming/stripping systems available for use with these cargo pumps are also examined. Pump operation is discussed, including the significant impact that system design has on proper pump performance.

Low Stiffness

This paper describes the practical design method of an advanced servo system for industrial robot manipulators, where it includes a disturbance and velocity observer. It is first assumed that the feature on frequency response of the robot is approximated to the feature of two-mass mechanism. Actually this is confirmed by some experiments. On the other hand, it is insisted that the actual servo system should be simple for industrial use. The observer is designed for the load which has the feature of single moment of inertia. Based on the assumption that there is a difference between these features, it is introduced that the servo system can be effectively used if only the qualified gains are selected considering lowstiffness. The special relation between the frequency analysis and the pole allocations are then shown, and Finally the experimental results are introduced.

A cryptology protocol for key distribution using phase and intensity fluctuation is proposed. It provides ways to detect the extent of eavesdropping. Detecting test factors and system design rules are suggested and the performances are analyzed for various signal keyings and cryptofunctions. It has a wide range of implementations, including the use of additive white Gaussian noise, background noise, and polarization modification in wire/wireless and optical communications.
