Abstract: When heavy equipment is moved by cranes or derricks—for example, in the course of manufacturing, assembly, or installation—the rigging or hitch used should be stable, i.e., it should not dump ...

Abstract: When heavy equipment is moved by cranes or derricks the rigging used must be stable. Based on the results in Part I, various sufficient stability criteria are derived which can be used to ...

Abstract: The synthesis of the parameters governing the dynamic response of high-speed cam-follower systems ideally involves an integrated approach capable of carrying out the tradeoffs necessary to achieve ...

Abstract: This part is concerned with the determination of optimum values of the design parameters of cam-follower systems according to the criterion developed in Part 1. The nonlinearities associated ...

Abstract: The control of artificial in-stream aeration of polluted rivers with multiple waste effluent sources is treated. The optimal feedback control law for this distributed parameter system is determined ...

Abstract: Pollution abatement by means of artificial aeration is considered for rivers which are contaminated by distributed effluent sources. The system model includes plant and observation noises to ...

Abstract: Regional planning for the abatement of pollution in a river drainage basin can profitably include artificial in-stream aeration as a key component in a coordinated abatement effort. This technique ...

Abstract: A general procedure has been developed for the kinematic analysis of complex bevel-gear trains in which the motion of the arm can be of mobility two or greater (i.e. the arm can rotate about ...

Abstract: This paper uses linear quadratic optimal control theory to design high-speed Dwell-Rise-Dwell (D-R-D) cams. Three approaches to D-R-D cam design are compared. In the first approach the cam is ...

Abstract: In civil engineering, the design of active vibration control systems for structures subjected to earthquake excitation is usually done using linear-quadratic optimal control theory. However, when this theory is applied to ...
