Generally, the feature parameters used for speech detection are highly sensitive to the environment. The performance of speech detection is severely degraded under realistic noisy environments since the characteristics of a speech signal cannot be fully expressed by those feature parameters. As a result, this study seeks the acoustic fingerprints of speech spectrogram as a robust feature to dis...

Object detection is one of the vital components used for autonomous navigation in dynamic environments. Camera and lidar sensors have been widely efficient object by mobile robots. However, they suffer from adverse weather conditions operating environments such as sun, fog, snow, extreme illumination changes day to night. The sensor fusion camera data helps enhance overall performance an networ...

We propose a novel feature mapping approach that is robust to channel mismatch, additive noise and to some extent, nonlinear effects attributed to handset transducers. These adverse effects can distort the short-term distribution of the speech features. Some methods have addressed this issue by conditioning the variance of the distribution, but not to the extent of conforming the speech statist...

R.J. Pignolo et al. (eds.), Fractures in the Elderly, Aging Medicine, DOI 10.1007/978-1-60327-467-8_2, © Springer Science+Business Media, LLC 2011 Abstract Pathologic fractures can be caused by any type of bone tumor, but the overwhelming majority of pathologic fractures in the elderly are secondary to metastatic carcinomas. Multiple myeloma is also common in the elderly and has a high incidenc...

An important feature of financial markets is that securities are traded repeatedly by asymmetrically informed investors. We study how current and future adverse selection affect the required return. We find that the bid-ask spread generated by adverse selection is not a cost, on average, for agents who trade, and hence the bid-ask spread does not directly influence the required return. Adverse ...
