Particle lift force and particle behavior in suspension flows
(1994)
In this study, particle lift force and its influence on particle behavior are considered in suspension flows. Saffman force, a particle lift force derived in parallel laminar shear flow, is extended to a general particle ...
Energy considerations in active vibratory systems
(1994)
Active vibration isolation systems can generally offer substantial improvements in dynamic performance. However, their use has been limited due to the burden of cost of their implementation and operation. The cost of ...
Condensation of a new alternative refrigerant flowing inside horizontal smooth tubes
(1994)
An experimental and analytical investigation of forced convective condensation in smooth circular tubes is performed for R-22 and R32+R125 mixture (50% by mass). The refrigerant is condensed by water inside a 0.315 inch ...
Understanding molecular and macroscopic relaxation processes in model epoxy resins : theoretical and practical aspects
(1994)
In the previous phase o f this research project completely phase separated and partially phase separated bimodal epoxy resins were prepared by incorporating a 22,500 weight average molecular weight advanced epoxy resin ...
An H formulation of the QFT approach to robust performance under significant uncertainties
(1994)
The main problem investigated in this research deals with the synthesis of controllers for achieving a desired robust performance in the presence of significant plant uncertainties. The robust performance problem is ...
A new objective function for robot calibration
(1994)
When using a robot, the operator usually desires to locate the tool accurately. To accomplish this, the operator should measure the tool position then use feedback to "drive" the manipulator in such a way that the tool ...
The experimental implementation and comparison of active, semiactive, and passive vehicle suspensions utilizing a linear electric motor
(Texas A&M University, 1994)
The primary objective of this research is the investigation of the experimental implementation of an active automobile suspension, three types of semiactive suspensions, and a passive suspension. These suspensions are ...
Thermodynamic, viscoelastic and rheological structure-property relationships of rigid poly(vinyl chloride)-styrenic copolymer blends
(1994)
In order to extend low temperature properties, rubber modification of PVC is commonly employed. The upper use temperature is however still restricted. To counter this problem modification using higher glass transition ...
System parameter analysis for robot manipulators with position-invariant natural frequencies
(1994)
The flexible PFBL (parallel-four-bar-linkage) link mechanism is designed to increase rigidity and to reduce the position variation of natural frequencies. The position variation of natural frequencies is the change of ...
