Low complexity two-dimensional digital filters using unconstrained SPT term allocation [PDF]
, 1996 Previous work by the authors has demonstrated how circularly symmetric and diamond-shaped low-pass linear phase 2-D FIR filters can be designed using coefficients comprising the sum or difference of two signed power-of-two (SPT) terms.

Simple Synchronous and Asynchronous Algorithms for Distributed Minimax Optimization
SICE Journal of Control, Measurement, and System Integration, 2017 Synchronous and asynchronous algorithms are presented for distributed minimax optimization. The objective here is to realize the minimization of the maximum of component functions over the standard multi-agent network, where each node of the network ...

Evaluating cutpoints for the MHI-5 and MCS using the GHQ-12: a comparison of five different methods
BMC Psychiatry, 2008 Background The Mental Health Inventory (MHI-5) and the Mental Health Component Summary score (MCS) derived from the Short Form 36 (SF-36) instrument are well validated and reliable scales. A drawback of their construction is that neither has a clinically

Statistics in Medicine, Volume 45, Issue 13-14, June 2026.ABSTRACT Depicting patient transitions among multiple clinical states is a common objective in health services and epidemiological research. Multistate models (MSM) are the primary analytical approach used in such studies. Although the structure of an MSM is typically determined by the research questions of a specific application, models are typically ...

Multiplicity of Solutions for Neumann Problems for Semilinear Elliptic Equations
Abstract and Applied Analysis, 2014 Using the minimax methods in critical point theory, we study the multiplicity of solutions for a class of Neumann problems in the case near resonance. The results improve and generalize some of the corresponding existing results.

Minimaxity of the Method of Regularization of Stochastic Processes
The Annals of Statistics, 1982 The idea of smoothing-spline interpolation is generalized to propose an estimator for the mean function of a stochastic process. A minimax property of the proposed estimator is then demonstrated under the usual squared loss function.

Worst-case estimation for econometric models with unobservable components. [PDF]
A worst-case estimator for econometric models containing unobservable components, based on minimax principles for optimal selection of parameters, is proposed. Worst-case estimators are robust against the averse effects of unobservables.

On Noncooperative Games, Minimax Theorems and Equilibrium Problems
In this chapter we give an overview on the theory of noncooperative games. In the first part we consider in detail for zero-sum (and constant-sum) noncooperative games under which necessary and sufficient conditions on the payoff function and different ...
