Consumers have recently become more concerned about food additives and food safety. Since its first meeting on September 17, 2003, the Risk Communication Expert Committee has studied and discussed the ideal methods to communicate risk related to food safety issues in response to a Food Safety Commission request. However, there are only a few case studies that actually apply to risk communicatio...

Due to their high reliability, fingerprints have been extensively used as a biometric identifier. The performance of an automatic fingerprint authentication system relies heavily on the fingerprint image quality as seen in several studies. In this work, we present a new method to quantify fingerprint image quality which is relevant to matcher performance. The ultimate goal of this research is t...

We present a fingerprint matching scheme that utilizes a ridge feature map to match fingerprint images. The technique described here obviates the need for extracting minutiae points to match fingerprint images. The proposed scheme uses a set of 16 Gabor filters, whose spatial frequencies correspond to the average inter-ridge spacing in fingerprints, is used to capture the ridge strength at equa...

Hybrid fingerprint matchers are well known as a powerful tool for high security applications where the reliability of a single fingerprint characteristic is not high enough for the intended application. In this paper, we propose a novel method, which due to its compressibility can be applied in memory constrained environments. This is important for application in smart cards and independent ide...

Pattern matching is the method of searching a pattern in a text. There are several existing algorithms which successfully locate the presence of a pattern in a text. In particular, Bioinfomaticians often search for a Deoxy-Ribo Nucleic Acid (DNA) pattern in a very long DNA sequence. These algorithms search the entire text in order to locate the pattern. Genetic algorithms, on the other hand, de...

Duplicate identification is a critical step in deep web data integration, and generally, this task has to be performed over multiple web databases. However, a customized matcher for two web databases often does not work well for other two ones due to various presentations and different schemas. It is not practical to build and maintain matchers for n web databases. In this paper, we target at b...

While there have been some evaluations and surveys of these evaluations, the overall effectiveness of currently available automatic schema matching systems is largely unclear. This is mainly because either the evaluations were conducted in diverse ways making it difficult to assess the effectiveness of each single system, or they were based on previously published information rather than on act...

Matching ontologies which utilize significantly heterogeneous terminologies is a challenging task for existing matching techniques. These techniques typically exploit lexical resources in order to enrich the ontologies with additional terminology such that more terminological matches can be found. However, they are limited by the availability of an appropriate lexical resource for each matching...

This paper proposes an effective algorithm based on the level set method (LSM) to solve shape and topology optimization problems. Since the conventional LSM has several limitations, a binary level set method (BLSM) is used instead. In the BLSM, the level set function can only take 1 and -1 values at convergence. Thus, it is related to phase-field methods. We don’t need to solve the Hamilton-Jac...

This work presents a method for optimum design of structures, where the design variables can he considered as Continuous or discrete. The variables are chosen as sizing variables as well as coordinates of joints. The main idea is to reduce the number of structural analyses and the overal cost of optimization. In each design cycle, first the structural response quantities such as forces, displac...
