In this paper we explored many versions of CELP codecs and studied different codebooks they use to encode noisy part of residual. Taking advantage of noise patterns they generated, an algorithm was proposed to detect GSM-AMR,EFR,HR and SILK codecs. Then it's extended to identify subframe offset to do tampering detection of cellphone speech recordings.
Acute myocardial infarction (AMI) is the death of cardiomyocytes caused by a lack of energy due to ischemia. Nutrients supplied by the blood are the main source of cellular energy for cardiomyocytes. Sodium butyrate (NaB), a gastrointestinal nutrient, is a short-chain fatty acid (butyric acid) that may act as an energy source in AMI therapy.… (More)
Viruses rely on host chaperone network to support their infection. In particular, the endoplasmic reticulum (ER) resident chaperones play key roles in synthesizing and processing viral proteins. Influx of a large amount of foreign proteins exhausts the folding capacity in ER and triggers the unfolded protein response (UPR). A fully-executed UPR comprises… (More)
Hyperspectral imaging has become one of the most promising and emerging technologies in remote sensing. It has made great advances in recent years by the introduction of new techniques, to take advantage of the vast amount of information contained within hyperspectral images (HSIs). However, the increase in the information comes at the expense of higher… (More)
In this thesis, we implement and test two algorithms for binary optimization and mixed integer optimization, respectively. We fine tune the parameters of these two algorithms and achieve satisfactory performance. We also compare our algorithms with CPLEX on large amount of fairly large-size instances. Based on the experimental results, our binary… (More)
