In this paper, an artificial stereo extension method of speech is proposed to control the width of auditory image. The proposed stereo extension method employs a decorrelator to make stereo-channel signals without any additional information from mono speech signal. In other words, uncorrelated signal is first generated from mono speech signal passing though the decorrelator, and it is added to ...

We describe a program called SketchIT that transforms a single sketch of a mechanical device into multiple families of new designs. It represents each of these families with a “BEP-Model,” a parametric model augmented with constraints that ensure the device produces the desired behavior. The program is based on qualitative configuration space (qc-space), a novel representation that captures mec...

A parametric model for the infrared signature caused by a buried land mine is presented. Further, a detector is calculated for the case where the background noise can be described by an autoregressive process. The detector separately estimates the parameters of the mine and the noise in an alternating fashion. The estimates are then used in the likelihood ratio test. Simulations show that signi...

This work is concerned with testing the population mean vector of nonnormal high-dimensional multivariate data. Several tests for high-dimensional mean vector, based on modifying the classical Hotelling T2 test, have been proposed in the literature. Despite their usefulness, they tend to have unsatisfactory power performance for heavy-tailed multivariate data, which frequently arise in genomics...

In 1982, Drezner proposed the (1|1)-centroid problem on the plane, in which two players, called the leader and the follower, open facilities to provide service to customers in a competitive manner. The leader opens the first facility, and the follower opens the second. Each customer will patronize the facility closest to him (ties broken in favor of the first one), thereby decides the market sh...

Many models of supersymmetry breaking, in the context of either supergravity or superstring theories, predict the presence of particles with Planck-suppressed couplings and masses around the weak scale. These particles are generically called moduli. The excessive production of moduli in the early Universe jeopardizes the successful predictions of nucleosynthesis. In this paper we show that the ...

Efficient heavy haul operations require accurate predictions of terminal arrival times and equipment cycle times. Most analytical and parametric approaches for railway capacity evaluation and operations planning focus on predicting average train delay and not the performance of individual trains and their delay distribution. In practice, train delay varies about this average according to some d...

In this paper we consider the problem of bounding the Betti numbers, bi(S), of a semi-algebraic set S ⊂ R k defined by polynomial inequalities P1 ≥ 0, . . . , Ps ≥ 0, where Pi ∈ R[X1, . . . , Xk] , s < k, and deg(Pi) ≤ 2, for 1 ≤ i ≤ s. We prove that for 0 ≤ i ≤ k − 1, bi(S) ≤ 1 2 + (k − s) + 1 2 · min{s+1,k−i}

The solar system r-abundance distribution is commonly derived from the observed solar values by subtracting the possible nucleosynthetic contribution of the s-process. The new parametric model of the s-process called the canonical multievent model is used to derive the s-component of the solar abundance distribution and to study the impact of nuclear and observational uncertainties on the solar...
