The wind-driven dynamic manipulator is a device which uses the wind tunnel freestream energy to drive multiaxis maneuvers of test models. This paper summarizes work performed using the device in several applications and discusses current work on characterizing the aerodynamics of an X-38 vehicle model in pitch-yaw maneuvers. Previous applications in flow visualization, adaptive control and line...

Flexible electronics are emerging as an alternative to conventional Si electronics for large-area lowcost applications such as e-paper, smart sensors, and disposable RFID tags. By utilizing inexpensive manufacturing methods such as ink-jet printing and roll-to-roll imprinting, flexible electronics can be made on low-cost plastics just like printing newspapers. However, the key elements of flexi...

This paper presents a new LPV/H∞ semi-active suspension control strategy for a commercial vehicle equipped with 4 Magneto-Rheological dampers. The proposed approach concerns road adaptation using on-line road profile identification based on a non linear algebraic observer with unknown input. Then, the suspensions forces distribution in each corner of vehicle is performed considering roll dynami...

key account business analyst, Quaker Chemical Corp., Conshohocken, Pa., USA [email protected] Nucor Steel Tuscaloosa Inc. is the first U.S. mill to employ Steckel mill technology for producing high-quality wide coiled plates and discrete plates. Since 1985, the Steckel mill has consistently demonstrated product versatility, quality and cost advantage over traditional plate mills. The single...

The roll angle is a crucial parameter for motorcycle dynamics. The ability of measuring it reliably in real time is an enabling technology for active control systems design for two-wheeled vehicles and for tire performance assessment. Nonetheless, it is quite difficult to devise the best trade-off between cost and precision and to choose the most appropriate sensor technology and lay-out. This ...

wk. Feed consumption, body weight and feed conversion were measured at 2, 4 and 6 wk. Carcass yield and weights of abdominal fat, gizzard and ceca were also determined at 6 wk. All birds were intramuscularly immunized with killed vaccine of Newcastle and Avian Influenza (H9 N2) at 8 d and antibody titer responses to Newcastle and Influenza were determined by hemagglutination inhibition (HI) tes...

Multi-antenna GPS receiver configurations and methods are assessed to determine roll, pitch and azimuth of a survey launch operating at cruising speeds of 10 to 15 knots. Two receiver configurations are inter-compared, namely a 4antenna Ashtech 3DF system and a 3-GPSCardTM configuration. The survey launch antenna configurations and marine trials conducted to test these systems are described. Th...

UNLABELLED Since its introduction in 1995, nanoimprint lithography has been demonstrated in many researches as a simple, low-cost, and high-throughput process for replicating micro- and nanoscale patterns. Due to its advantages, the nanoimprint lithography method has been rapidly developed over the years as a promising alternative to conventional nanolithography processes to fulfill the demands...

The stability of multi-input and multi-output web-tension systems is an important factor that is required for the roll-to-roll printing machines. This paper analyzes stability for design parameters of a web-tension system of a high-speed gravure printing machine. Analyzed parameters include moment of inertia of the passive dancer, viscous friction coefficient of the dancer system, distances fro...

A novel roll-to-roll flexographic printing process for rechargeable zinc-based battery manufacturing was presented in this paper. Based on the fundamental operating mechanism of flexography, key criteria for developing functional flexographic printing inks were established, including composite ink rheology (steady-state viscosity and yield stress), ink wettability as well as ink dispersing qual...
