In this paper we introduce a novel method of fingerprint alignment that uses the intrinsic geometric properties of minutiae-based triangles combined with the geometric invariant. The minutiae points are extracted from the fingerprint image and a Delaunay (DL) triangulation is constructed from these minutiae points resulting in a series of triangles. Corresponding minutiae points are established using local affine invariants constructed from the local minutia-based triangles. Triangles that are distorted by noise or have no counter part on the query are discarded. We rely only on "strong" matches that are reliable and present, for example, where the error metric between the local absolute invariants is below a set threshold. The correspondences of such matches are then used to estimate transformation parameters. The performance of our method is represented by computing the distance map error between a template and a query fingerprint after undoing the transformation, computed from the ridge structures of the two fingerprints. In conclusion, the proposed method can be used to find the corresponding minutiae and align any fingerprints considered into affine transformation, in the presence of noise including the partial occlusion.

In this paper, we develop a multi-objective network design model for the traffic grooming, routing and wavelength assignment (GRWA) in WDM networks. We consider and evaluate four traffic grooming strategies which are Point to Point (P2P), Point to Multi-Point (P2MP), Multi-Point to Point (MP2P) and Multi-Point to Multi-Point (MP2MP). The design objectives are to maximize the number of accepted communication requests (source-destination pairs) as well as to minimize the number of wavelength channel requirement. Both the design objectives are conflicted to each other;maximizing the number of accepted commodities will require a large number of wavelength channels while minimizing the number of wavelength channels will limit the amount of accepted commodities. To solve the multi-objective network design problem, we apply a fast and efficient optimization technique called "Fast Non-dominated Sorting Genetic Algorithm (NSGA-II)". The simulation results show that traffic grooming with multiple sources/destinations are the most flexible and efficient grooming techniques that give wide-spread solutions on the objective space, than those solutions obtained from the P2P grooming technique in both objective values (i.e., number of accepted commodities and wavelength channels required).

This paper considers a multi-objective network design problem for the traffic grooming, routing and wavelength assignment (GRWA) in WDM networks. The design objectives are to maximize the number of accepted communication requests (source-destination pairs) as well as to minimize the number of wavelength channel requirement. Both the design objectives are conflicted to each other;maximizing the number of accepted commodities will require a large number of wavelength channels while minimizing the number of wavelength channels will limit the amount of accepted commodities. To solve the multi-objective network design problem, we apply a fast and efficient optimization technique called "Fast Non-dominated Sorting Genetic Algorithm (NSGA-II)". In this paper, traffic grooming (GA-LMF) and non-traffic grooming (GA-MDF and FAR-FF) algorithms are compared and benchmarked for solving the multi-objective design problem. The results show that the GA-LMF is the most flexible and efficient grooming technique. The obtained solutions from the GA-LMF are spread on the objective space and are better than those from other non-grooming techniques in both objective values (i.e., number of accepted commodities and wavelength channels required).

In this paper, the cause of significant variation in sensing responses of identical QCM sensors array in a circular QCM chamber is analyzed by fluid dynamic simulation. Moreover, the simulation is used to determine an appropriate shape of flow chamber for QCM sensor array. Simulation results show that the flow in a circular-shaped QCM chamber design is primarily turbulent. In addition, the degree of turbulence is increased with flow rate. Thus, sensors at various locations see different sample dispersions causing their sensing behaviors to be significantly different. The QCM chamber has been redesigned to be rectangular line and simulation results indicate that it can be the solution to the problem because flow in the new design is primarily laminar with uniform sample velocity.
