Asymptotic Optimality of Sequential Designs for Estimation
This paper is concerned with the problem of allocating a fixed number of trials between K independent populations from the exponential family, in order to estimate a linear combination of the means with squared error loss. ...
Optimality Conditions for Systems Driven by Nonlinear Evolution Equations
Using the Dubovitskii-Milyutin theory we derive necessary and sufficient conditions for optimality for a class of Lagrange optimal control problems monitored by a nonlinear evolution equation and involving initial and/or ...
Bulk input queues with quorum and multiple vacations
The authors study a single-server queueing system with bulk arrivals and batch service in accordance to the general quorum discipline: a batch taken for service is not less than r and not greater than R(≥r). The server ...
A sturm separation theorem for a linear 2nth order self-adjoint differential equatio
For the 2nth order equation, (−1)nv(2n)+qv=0, with q continuous, we obtain a Sturm Separation theorem, involving n+1 solutions of the equation, which is somewhat analogous to the classical result that the zeros of two ...
Hubble space telescope observations of cool white dwarf stars: Detection of new species of heavy elements
Observations of cool white dwarf stars with the Hubble Space Telescope has uncovered a number of spectral features from previously unobserved species. In this paper we present the data on four cool white dwarfs. We present ...
