Using automatic speech recognition (ASR) word error rates (WERs) as a metric, the systems in (1) and (3) appear to have yield similar performance, in spite of significant additional architectural differences. Systems of type (2) have not been fielded for segmentation for ASR, and therefore cannot be directly compared. Although approaches of type (3) offer a significant advantage, namely the opp...

We present an approach for pricing of illiquid bonds (and bond derivatives) in an arbitrage-free way and consistently with observed prices of liquid bonds. The basic model is a multifactor term structure model with abstract latent factors. The approach is based on stochastic filtering techniques, leading to a continuous update of the distribution of the latent factors on the basis of the inform...

Abstract: In this paper we consider point control of a structural acoustic model with thermoelastic effects. The key feature of this paper is that the two-dimensional plate modeling the active wall of the acoustic chamber has clamped boundary conditions. For this case a new optimal regularity result has recently become available (Triggiani, 2008). Using this new result for the plate alone, we d...

In this paper, the acoustic environment in a vehicle cabin under the influence of highfrequencies aerodynamic sources has been studied. Some panels on the windshield, the roof, the doors, the front pillars, and the floor of a vehicle simulated as input source of noise when the car is moving at high speed, i.e. 112 km/h. The status of vehicle cabin in each of these modes has been studied and com...

In this paper we present a numerical and experimental investigation of the properties of the ARMARKOV adaptive control (AAC) algorithm with simultaneous identification. This algorithm requires a model of only the secondary path (control input to performance variable) transfer function which is identified online using the time-domain ARMARKOV/Toeplitz identification technique. For a 5-mode acous...
