Exact eigenvalue assignment of linear scalar systems with single delay using Lambert W function
, 2018 Eigenvalue assignment problem of a linear scalar system with a single discrete delay is analytically and exactly solved. The existence condition of the desired eigenvalue is established when the current and delay states are present in the feedback loop ...

Spectral redemption: clustering sparse networks [PDF]
, 2013 Spectral algorithms are classic approaches to clustering and community detection in networks. However, for sparse networks the standard versions of these algorithms are suboptimal, in some cases completely failing to detect communities even when other ...

Partial Eigenvalue Assignment for Undamped Gyroscopic Systems in Control
East Asian Journal on Applied Mathematics, 2019 The solvability of a partial eigenvalue assignment problem for undamped gyroscopic control systems is proved and its explicit solutions are found. In addition, the problem of replacing certain eigenvalues by required ones while keeping the remaining ...

On Pole Placement and Invariant Subspaces
, 2013 The classical eigenvalue assignment problem is revisited in this note. We derive an analytic expression for pole placement which represents a slight generalization of the celebrated Bass-Gura and Ackermann formulae, and also is closely related to the ...

Decentralized PI Controller Design by Eigenvalues Assignment
IFAC Proceedings Volumes, 2000 A procedure for designing proportional, integral,and derivative (PID) decentralized controllers based on eigenvalues assignment techniques is presented. The advantage of such a procedure is the extra flexibility offered where it allows one to govern the rate of decay and achieve certain performance characteristics besides the well-known properties of ...

Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Holant Problems for Regular Graphs with Complex Edge Functions [PDF]
, 2010 We prove a complexity dichotomy theorem for Holant Problems on 3-regular graphs with an arbitrary complex-valued edge function. Three new techniques are introduced: (1) higher dimensional iterations in interpolation; (2) Eigenvalue Shifted Pairs, which ...
