Maximizing the lowest eigenvalue of a constrained affine sum with application to the optimal design of structures and vibrating systems
Autor: S G Krishna, Y M Ram
Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science. 223:583-593
This article deals with the problem of maximizing the lowest eigenvalue of an affine sum of symmetric matrices subject to a constraint. It is shown that by the repeated use of eliminants, the problem may be reduced in a systematic manner to that of f

A method for finding repeated roots in transcendental eigenvalue problems
Autor: Y M Ram
Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science. 222:1665-1671
The eigenvalues of a gyroscopic system depend on a parameter, and the system may become unstable when eigenvalues collide. For continuous systems, the eigenvalue problem is represented by a matrix with transcendental elements. A method is developed t

An Inverse Problem Associated With Modification of Incomplete Dynamic Systems
Autor: Y. M. Ram, Simon Braun
Publikováno v: Journal of Applied Mechanics. 58:233-237
Given an incomplete set of natural frequencies and modes of a linear structure from a vibration test, the problem of computing the necessary changes in the structure to reach a desired spectra is considered. A criterion of optimality which gives the

Dynamics of Contagious Disease
Autor: Y. M. Ram, J. Caldwell
Publikováno v: Mathematical Modelling ISBN: 9789048152636
This case study considers a deterministic model in the theory of contagious disease. The major assumption made is that all infected individuals remain in the population to spread the disease. For this particular case an exact solution can be obtained

The Design of Biotreatment Systems
Autor: Y. M. Ram, J. Caldwell
Publikováno v: Mathematical Modelling ISBN: 9789048152636
Polluted water is discharged from a steelworks and the management have been ordered by the authorities to install an effluent system to ‘clean up’ the pollution before the water enters the local river. In particular, this system must ensure that
