In recent years, demands for distributing or searching multimedia contents are rapidly increasing and more effective method for multimedia information retrieval is desirable. In the studies on spoken document retrieval systems, much research has been presented focusing on the task of spoken term detection (STD), which locates a given search term in a large set of spoken documents. One of the mo...

In this chapter experience with solving quadratic assignment problems is reported. The results reported in this chapter are the best results for heuristic solutions of the quadratic assignment problem available to date and can serve as bench mark results for future researchers who propose new approaches for solving quadratic assignment problems. The most effective method to date for solving qua...

Finger-vein is a promising biometric technique for the identity authentication. However, the finger displacement or the illumination variation in image capturing may cause bad recognition performance. To overcome these limitations, multi-biometric system, an effective method to improve the performance, is proposed. In this paper, a new multimodal biometric system based on pixel level feature an...

— Steganography is about how to send secret message covertly. And the purpose of steganalysis is to not only detect the existence of the hidden message but also extract it. So far there have been many reliable detecting methods on various steganographic algorithms, while there are few approaches that can extract the hidden information. In this paper, the difficulty of extracting hidden informat...

Nearest Neighbour (NN) classification is a widely-used, effective method for both binary and multi-class problems. It relies on the assumption that class conditional probabilities are locally constant. However, this assumption becomes invalid in high dimensions, and severe bias can be introduced, which degrades the performance of the method. The employment of a locally adaptive distance metric ...

Wind erosion is considered as one of the main processes of land degradation in different parts of the world. Among the most effective ways to control wind erosion is to cover land surface with natural vegetation area. In this study, 3 replica soil samples were collected, at a depth of 0-3 cm, from various land uses in Dehloran, Ilam Province, Iran. Physical and chemical characteristics of soil ...

  Background : Studies have shown a gradual decline in empathy of medical trainees with increasing years of education. Methods to augment empathy show some promise, but the most effective methods are both expensive and time consuming.To assess effectiveness of communication skills training program as a distant learning method in improving empathy.   Method s: Fourteen first year residents of ps...

in this paper, the security of a distance bounding protocol is analyzed which has been recently proposed by jannati and falahati (so-called jf). we prove that an adversary can recover key bits of jf protocol with probability of “1” while the complexity of attack is “2n” runs of protocol. in addition, we propose an improved protocol and prove that the improved protocol is resistant to mafia frau...
