The cardiac left insufficiency with mitral dysfunction is a relevant pathology importante repercussion in the lung, leads to pulmonary edema. Pulmonary edema corresponds accumulation of fluid lung parenchyma and alveoli, can be classified as cardiogenic or non-cardiogenic. Clinical signs symptoms include presence dyspnea, cough, tachypnea, alteration normal sounds during auscultation. In this c...

Optimization problems in design engineering are complex by nature, often because of the involvement of critical objective functions accompanied by a number of rigid constraints associated with the products involved. One such problem is Economic Load Dispatch (ED) problem which focuses on the optimization of the fuel cost while satisfying some system constraints. Classical optimization algorithm...

This paper studies optimization of tool path planning in 5-axis flank milling of ruled surfaces using advanced Particle Swarm Optimization (PSO) methods with machining error as an objective. We enlarge the solution space in the optimization by relaxing the constraint imposed by previous studies that the cutter must make contact with the boundary curves. Advanced Particle Swarm Optimization (APS...

Image enhancement plays a crucial role in almost every image processing system. The main aim of the image enhancement is to improve image quality by maximizing the information content in the given input image. Histogram Equalization (HE) and Adaptive Histogram Equalization (AHE) are most popular non-heuristic or classical techniques for image enhancement by preserving main features of the input...

Hierarchical based clustering protocol for wireless sensor network is suitable to use in energy efficient environmental monitoring. In clustering protocol, sensor nodes that are cluster heads (CHs) have to collect information from cluster member and transmit to the base station. Strategic CHs location can significantly affect the network overall energy consumption. Therefore, selecting suitable...

The research aims to improve prediction accuracy for heights of fractured water-conducting zones (FWCZs) and effectively prevent control roof water disasters, ensure safe coal mining. For this purpose, the method that integrates improved cuckoo search (ICS) algorithm extreme learning machine (ELM) is used predict FWCZs. Based on an analysis factors influencing FWCZs, ICS employed optimize two k...

An efficient method based on the hybrid model with breeding and subpopulations, between genetic algorithm and a modified particle swarm optimizer for the linear antenna arrays pattern synthesis with prescribed nulls in the interference direction and multi-lobe beam forming by the complex weights of each array element is presented. In general, the pattern synthesis technique that generates a des...

Accurately predicting the surface finish of fused deposition modeling (FDM) parts is an important task for engineering application FDM technology. So far, many prediction models have been proposed by establishing a mapping relationship between printing parameters and roughness. Each model can work well in its specific context; however, existing cannot meet requirements multi-factor multi-catego...
