a study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
mortality forecasting based on lee-carter model
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
15 صفحه اولMethod of LP-based blind restoration for improving intelligibility of bone-conducted speech
Bone-conducted (BC) speech in an extremely noisy environment is stable against surrounding noise so that it may be able to be used instead of air-conducted (AC) speech for communication. However, it has very poor sound quality and its intelligibility is degraded when transmitted through bone conduction. Therefore, voice-quality and the intelligibility of BC speech need to be blindly improved in...
متن کاملModel-based speech enhancement using a bone-conducted signal.
Codebook-based single-microphone noise suppressors, which exploit prior knowledge about speech and noise statistics, provide better performance in nonstationary noise. However, as the enhancement involves a joint optimization over speech and noise codebooks, this results in high computational complexity. A codebook-based method is proposed that uses a reference signal observed by a bone-conduct...
متن کاملGaussian Mixture Model Based Coding of Speech and Audio
The transmission of speech and audio over communication channels has always required speech and audio coders with reasonable search and computational complexity and good performance relative to the corresponding distortion measure. This work introduces a coding scheme which works in a perceptual auditory domain. The input high dimensional frames of audio and speech are transformed to power spec...
