Usually, we need a large number of testing samples to evaluate the performance of automatic speaker verification (ASV) systems. The equal error rate (EER) is a common measure for this purpose. It is derived according to the threshold determined by finding the verification score when the false rejection rate (FRR) equals to the false acceptance rate (FAR). In this paper, a method of model-based ...

Automated fingerprint identification system has an increasingly important role in modern times. This study presents the steps of the automated fingerprint identification system and presents an application for fingerprint identification and system's equal error rate evaluation. The algorithm for fingerprint image enhancement is a key element of the system. A fingerprint image can be damaged, dam...

Speaker verification technologies have many commercial applications, such as direct banking, cellular transactions, credit card operations and E-Commerce. Voice based verification can answer the need for a secure, friendly and cost effective authentication tool required by the finance, commerce and Telecommunication markets. Introducing an operational large-scale system to the market requires m...

Loss functions are widely used to compare several competing forecasts. However, forecast comparisons often based on mismeasured proxy variables for the true target. We introduce concept of exact robustness measurement error loss and fully characterize this class as Bregman class. Hence, only conditional mean forecasts can be evaluated exactly robustly. For such robust functions, differences ave...

As a way of implementing multicast delivery, applicationlevel multicast (ALM) is known for its various advantages including high flexibility and easy deployment. However, one of its key limitations in achieving reliability and quality-of-service (QoS) for streaming services is the hierarchical error propagation caused by its tree structure. As a solution to this error propagation problem, we pr...

Gas-condensate reservoirs contain hydrocarbon fluids with characteristics between oil and gas reservoirs and a high gas-liquid ratio. Due to the large gas-liquid ratio, wellhead choke calculations using the empirical equations such as Gilbert may contain considerable error. In this study, using drill stem test (DST) data of a gas-condensate reservoir, coefficients of Gilbert equation was modifi...
