High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...

Experimental design is a powerful approach to study the impact of potential variables affecting systems and provides spontaneous insight for continuous improvement possibilities. Most research in system design has focused on problems with a single characteristic or response. This paper is concerned with the application of a design method to problems with multiple characteristics. The study sequ...

As tape recording density increases, high-frequency track following capability of the tape head actuator becomes more important. This paper details the mechanical design and experimental analysis of a dual state actuator tape head. The dual stage actuator design combines a traditional voice coil motor for low frequency track following with a piezoelectric actuator for high-frequency track follo...

Self-compacting concrete is a fluid mixture suitable for placing in structures with congested reinforcement without vibration. Self-compacting concrete development must ensure a good balance between deformability and stability. Also, compactibility is affected by the characteristics of materials and the mix proportions; it becomes necessary to evolve a procedure for mix design of SCC. The paper...

A method for sequence optimization in protein models is presented. The approach, which has inherited its basic philosophy from recent work by Deutsch and Kurosky @Phys. Rev. Lett. 76, 323 ~1996!# by maximizing conditional probabilities rather than minimizing energy functions, is based upon a different and very efficient multisequence Monte Carlo scheme. By construction, the method ensures that ...

One of the major problems within the VHDL based behavioral synthesis is to start the design on higher abstraction level than the register transfer level (RTL). VHDL semantics was designed strictly for simulation, therefore it was not considered as high-level synthesis language. A novel synthesis procedure was developed, which uses the methodology of high level synthesis. It starts from an abstr...
