High-quality mammography is the most effective technology presently available for breast cancer screening. Efforts to improve mammography focus on refining the technology and improving how it is administered and X-ray films are interpreted. Computer-based intelligent system for identification of the breast cancer can be very useful in diagnosis and its(More)
Magnetic-field-induced phase transitions in the integer quantum Hall effect are studied under the formation of paired Landau bands arising from Zeeman spin splitting. By investigating features of modular symmetry, we showed that modifications to the particle-hole transformation should be considered under the coupling between the paired Landau bands. Our(More)
In this paper we study model parameter compensation methods for noise-robust speech recognition based on CDHMM. First, we propose a modified PMC method where adjustment term in the model parameter adaptation is varied depending on mixture components of HMM to obtain more reliable modeling. A state-dependent association factor that controls the average(More)
