Intelligent Techniques for Photocatalytic Removal of Pollution in Wastewater

Journal of Electrical Engineering 2017年第6期5卷 321-328页

作者： sina Razvarz Raheleh Jafari Departamento de Control Automatico CINvESTA v-IPN (National Polytechnic Institute) Mexico City 07360 Mexico

This paper discusses the elimination of C.I. AY23 （Acid Yellow 23） using Uv/Ag-TiO2 process. To anticipate the photocatalytic elimination of AY23 with the existence of Ag-TiO2 nanoparticles processed under desired circumstances, two computational techniques namely NN （neural network） and PSO （particle swarm optimization） modeling are developed. A summed up of 100 data are used to establish the models, wherein introductory concentration of dye, Uv light intensity, initial dosage of nano Ag-TiO2 and irradiation time are the four parameters applied as the input variables and elimination of AY23 as the output variable. The comparison among the predicted results by designed models and the experimental data proves that the performance of the NN model is comparatively sophisticated than the PSO model.

In the present state of the art,ion beam sputtering is used to produce low-loss dielectric *** the manufacturing of a dielectric layer stack,the deposition material must be changed,which requires rapid mechanical movement of vacuum *** mechanical components can be regarded as a risk factor for contamination during the coating process,which limits the quality of high-end laser *** minimize the particle contamination,we present a novel deposition concept that does not require movable components to change the coating material during the coating process.A magnetic field guiding technique has been developed,which enables the tuning of the refractive index in the layer structure by sputtering mixtures with varying compositions of two materials using a single-ion *** versatility of this new concept is demonstrated for a highreflection mirror.

We present a laser resection technique to be used when biotissue is heated by laser radiation to the temperature of material softening and then moved apart by the lateral edge of the optical fiber with a strongly absorbing tip. The absorbing tip allows the decrease in the power of effective cutting of the laser scalpel at the wavelength of 0.97 μm. And it changes the resection speed as well as the characteristics of the damage of the tissues adjacent to the incision in experiments on model media and experimental animals.

Objective:To present clinical and pathologic features of pulmonary hyalnizing granuloma through analyzing three cases found in our institution and reviewing cases reported in the English language *** and Results:Three cases of pulmonary hyalnizing granuloma identified at our institution during the past ten years were reviewed. In the first case,the patient presented with concurrent pulmonary hyalinizing granuloma and histoplasmosis. In the second case,the patient presented with a 5.5 cm lung mass and a separate smaller lesion radiologically resembling bronchogenic carcinoma. There was very prominent polyclonal lymphocytic proliferation at the periphery especially of the smaller lesion likely representing an early stage of the disease process. In the third case,the patient presented with multiple subpleural plaque-like lesions in addition to nodular lesions of the lung. All cases also demonstrated various degrees of lymphocytic infiltration within the lesions. The English literature has been reviewed through searching the ***:Since patients with pulmonary hyalinizing granuloma demonstrated a spectrum of clinical presentations,radiologic changes and histologic features with a variety of associated clinical disorders,pulmonary hyalnizing granuloma is more in keeping with a clinicopathologic entity rather than a specific pathologic disease.
