Physically-based radiative transfer models (RTMs) help understand the interactions of radiation with vegetation and atmosphere. However, advanced RTMs can be computationally burdensome, which makes them impractical in many real applications, especially when many state conditions and model couplings need to be studied. To overcome this problem, it is proposed to substitute RTMs through surrogate...

We propose an attention mechanism in deep learning networks for gender recognition using the gaze distribution of human observers when they judge people pedestrian images. Prevalent mechanisms spatially compute correlation among values all cells input feature map to calculate weights. If a large bias background images (e.g., test samples and training containing different backgrounds) is present...

Ti6Al4V alloy is widely used in aerospace and medical applications. It classified as a difficult to machine material due its low thermal conductivity high chemical reactivity. In this study, hybrid intelligent models have been developed predict surface roughness when end milling with Physical Vapor Deposition PVD coated tool under dry cutting conditions. Back propagation neural network (BPNN) h...

This paper presents a novel heuristic optimization method to solve complex economic load dispatch problem using a hybrid method based on particle swarm optimization (PSO) and gravitational search algorithm (GSA). This algorithm named as hybrid PSOGSA combines the social thinking feature in PSO with the local search capability of GSA. To analyze the performance of the PSOGSA algorithm it has bee...

This paper describes a compiler framework that enhances the detection of parallelism in loops with complex irregular computations. The framework is based on the static analysis of the Gated Single Assignment (GSA) program representation. A taxonomy of the strongly connected components (SCCs) that appear in GSA dependence graphs is presented as the basis of our framework. Furthermore, an algorit...

Constraint automata are a semantic model for XML modeling language. Testing correctness of mapping black-box components in XML to constraint automata is an important problem in analyzing the semantic model of XML and requires a collection of test data that cover different scenarios. In this paper, Genetic Algorithm (GA) is employed to generate such set of test cases. This test data generation i...

This document defines the common architecture for Multicast Security (MSEC) key management protocols that support a variety of application, transport, and network layer security protocols. It also defines the group SA (GSA), and describes the key management protocols that help establish a GSA. The framework and guidelines described in this document allow for a modular and flexible design of gro...
