MathOptimizer: a nonlinear optimization package for mathematica users
(2009)
Mathematica is an advanced software system that enables symbolic computing, numerics, program code development, model visualization and professional documentation in a unified framework. Our MathOptimizer software package ...
Improving automatic emotion recognition from speech signals
(International Speech Communications Association, 2009)
We present a speech signal driven emotion recognition system. Our system is trained and tested with the INTERSPEECH 2009 Emotion Challenge corpus, which includes spontaneous and emotionally rich recordings. The challenge ...
Approximation algorithms for single machine scheduling with one unavailability period
(Springer Nature, 2009-03)
In this paper, we investigate the single machine scheduling problem with release dates and tails and a planned unavailability time period. We show that the problem admits a fully polynomial-time approximation scheme when ...
Pseudoscalar-meson-octet-baryon coupling constants in two-flavor lattice QCD
(American Physical Society, 2009-04-01)
We evaluate the πΝΝ, π∑∑, πΛ∑, KΛN and K∑N coupling constants and the corresponding monopole masses in lattice QCD with two flavors of dynamical quarks. The parameters representing the SU(3)-flavor symmetry are computed ...
Optimal solution of the discrete cost multicommodity network design problem
(Elsevier, 2008-10-15)
We investigate a multicommodity network design problem where a discrete set of Technologies with step-increasing cost and capacity functions should be installed on the edges. This problem is a fundamental network design ...
On the broadcast capacity of wireless multihop interference networks
(IEEE, 2009)
This paper is concerned with wireless broadcasting in multihop networks where a selected number of relay nodes may aid the source node in the broadcast under a given total energy and hop constraint. We study an ad-hoc ...
Heuristics for the variable sized bin-packing problem
(Elsevier, 2009-10)
We investigate the one-dimensional variable-sized bin-packing problem. This problem requires packing a set of items into a minimum-cost set of bins of unequal sizes and costs. Six optimization-based heuristics for this ...
Capacity of wireless ad-hoc broadcast networks under realistic channel models
(IEEE, 2009)
In a wireless broadcasting scenario, some of the nodes can help the source node by forwarding the received information. Due to the interference from multiple transmissions, selection of these nodes directly affects the ...
Solution of near-field thermal radiation in one-dimensional layered media using dyadic Green's functions and the scattering matrix method
(Elsevier, 2009-12)
A general algorithm is introduced for the analysis of near-field radiative heat transfer in one-dimensional multi-layered structures. The method is based on the solution of dyadic Green's functions, where the amplitude of ...
Metal CMP optimization based on chemically formed thin film analysis
(The Electrochemical Society, 2009)
The conventional demands for development in semiconductor industry are changing as the Moore's Law is approaching to its limits. This paper demonstrates a theoretical optimization approach for the planarization of metal ...
