the geometric distribution of states duration is one of the main performance limiting assumptions of hidden markov modeling of speech signals. stochastic segment models, generally, and segmental hmm, specifically, overcome this deficiency partly at the cost of more complexity in both training and recognition phases. in this paper, a new duration modeling approach is presented. the main idea of ...

Surgical simulation has many applications in education and training, surgical planning, and intra-operative assistance. However, extending current surface-based computer graphics methods to model phenomena such as the deformation, cutting, tearing, or repairing of soft tissues pose significant challenges for real-time interactions. In this paper, the use of volumetric methods for modeling compl...

introduction: there is many ways to assessing the electrical conductivity anisotropy of a tumor. applying the values of tissue electrical conductivity anisotropy is crucial in numerical modeling of the electric and thermal field distribution in electroporation treatments. this study aims to calculate the tissues electrical conductivity anisotropy in patients with sarcoma tumors using diffusion ...
