Bit allocation is essential for a video encoder to accurately control the generated bits, and thus greatly influences the visual quality.In this paper, an improved bit ROMPERS allocation algorithm is proposed at the frame level for the emerging Scalable High-efficiency Video Coding (SHVC) standard.At the spatial base and enhancement layers, the bit
Bayesian latent class models for identifying canine visceral leishmaniosis using diagnostic tests in the absence of a gold standard.
BackgroundLike many infectious diseases, there is no practical gold standard for diagnosing clinical visceral leishmaniasis (VL).Latent class modeling has been proposed to estimate a latent gold standard for identifying disease.These proposed models for VL have leveraged information from diagnostic tests with dichotomous serological and PCR assays,
Type 1 diabetes mellitus: retrospect and prospect
Abstract Background Type 1 diabetes (T1D) is an autoimmune disease leading to destruction of insulin-producing pancreatic beta cells.Both genetic and environmental factors contribute to pathogenesis.The incidence of T1D is increasing worldwide, with significant geographic and ethnic variations.Patients present with symptoms of hyperglycemia and dia
Fire risk Assessment in Multi-story Commercial Buildings Using Computerized Fire Safety Evaluation System: A Case Study in Shiraz
Background: The occurrence of fire in buildings inflicts considerable damage on communities and individuals.This issue is very important in multi-story commercial buildings due to the high fire load, large and untrained population, high value of building and its equipment, complexity of emergency evacuation, and firefighting operations.This study w
