in this paper, the crack detection and depth ratio estimation method are presented in beamlikestructures using elman networks. for this purpose, by using the frequencies of modes asinput, crack depth ratio of each element was detected as output. performance of the proposedmethod was evaluated by using three numerical scenarios of crack for fixed-simply supportedbeam consisting of a single crack...
Research and development of Spectrum Administration for metallic access networks analyzed possibilities of matrix representation for transmission circumstances. Some interesting remarks were gained as a side output of this work.
BACKGROUND The National Cancer Institute of Canada Clinical Trials Group CO.17 study showed that patients with advanced colorectal cancer had improved overall survival when cetuximab, an epidermal growth factor receptor-targeting antibody, was given in addition to best supportive care. We conducted a cost-effectiveness analysis using prospectively collected resource utilization and health utili...
An integrated membrane distillation (MD) flowsheet, consisting of direct contact (DCMD) and vacuum (VMD) units, was proposed analysed in terms thermal performance water recovery factor, for the first time. The same lab-scale module (40 cm2) used carrying out experiments DCMD VMD at fixed feed operating conditions (deionised 230 L/h ~40 °C) while working permeate side with deionised 18 °C a 20 m...
OBJECTIVE To analyze the cost-utility of using extracorporeal oxygenation for patients with severe acute respiratory distress syndrome in Brazil. METHODS A decision tree was constructed using databases from previously published studies. Costs were taken from the average price paid by the Brazilian Unified Health System (Sistema Único de Saúde; SUS) over three months in 2011. Using the data of...
Humidification dehumidification desalination (HDH) is a promising technology for small-scale water production applications. There are several embodiments of this technology which have been investigated by researchers around the world. However, from a previous literature review [1], we have found no study which carried out a detailed thermodynamic analysis in order to improve and/or optimize the...

This article applies nonlinear programming techniques to optimize humidification-dehumidification (HD) desalination cycles for operating conditions that result in maximum gained output ratio (GOR). Closed air open water as well as open air open water cycles, each with either an air or a water heater, were considered in this analysis. Numerical optimization resulted in a substantial increase in ...
Abstract The main purpose of this paper is to build a family tutorial Goodwinian (essentially Marxist) models capital accumulation through industrial cycles that are less complicated than the author’s extended capitalist reproduction in USA already published. subordinate advance refinement these from standard “neoclassical” assumptions distort generic structures determining perpetual disequilib...
