H8 control state feedback and Rayleigh quotient
, 2001 Based on the analogy between structural mechanics and optimal control, the optimal parameter ??2cr of state feedback H8 control is shown to correspond to the fundamental Rayleigh quotient eigenvalue in structural stability or to structural vibration ...

Embedding negative structures to model holes and cut-outs
, 2009 It has now been established that geometric boundary conditions and continuity conditions can be modelled by using either positive or negative stiffness or inertia type penalty term [1-5].

Hybrid parallel computation of transcendental structural eigenvalues
, 1995 Existing coarse grain and fine grain methods are refined to enable the efficient calculation of natural frequencies and critical buckling loads of structures on parallel computers, using the Wittrick-Williams algorithm to solve the transcendental ...

Kron's method: an algorithm for the Eigenvalue analysis of large-scale structural systems [PDF]
, 1972 In this report, the Kron eigenvalue procedure is established by the application of Hamilton's principle to a constrained primitive Lagrangian, comprising the characteristics of the various sub-systems into which a composite system is 'torn' to facilitate

A memetic fingerprint matching algorithm [PDF]
, 2007 Minutiae point pattern matching is the most common approach for fingerprint verification. Although many minutiae point pattern matching algorithms have been proposed, reliable automatic fingerprint verification remains as a challenging problem, both with

Listing 6-Cycles in Sparse Graphs [PDF]
This work considers the problem of output-sensitive listing of occurrences of 2k-cycles for fixed constant k ≥ 2 in an undirected host graph with m edges and t 2k-cycles. Recent work of Jin and Xu (and independently Abboud, Khoury, Leibowitz, and Safier)
