Demonstration of Artificial Neural Network
Artificial neural networks (ANN) is referred as the neural networks are the signal processing and in information model which is based on the biological neuron. An artificial neural network (ANN) consists of a bundle of simple processing units which communicate by sending signals to each other over a large number of weighted connections. A set of processing unit is called as neuron. A neural network is made up of an interconnection of nonlinear neuron. The purpose of this work is to examine Neural Networks (NN) and their emerging applications in the field of engineering.The paper presented the basic study of the artificial neural network and its characteristics and its applications
Microwave-Assisted Synthesis of Titania Nanocubes, Nanospheres and Nanorods for Photocatalytic Dye Degradation
TiO2nanostructures with fascinating morphologies like cubes, spheres, and rods were synthesized by a simple microwave irradiation technique. Tuning of different morphologies was achieved by changing the pH and the nature of the medium or the precipitating agent. As-synthesized titania nanostructures were characterized by X-ray diffraction (XRD), UV–visible spectroscopy, infrared spectroscopy (IR), BET surface area, photoluminescence (PL), scanning electron microscopy (SEM) and transmission electron microscopy (TEM), and atomic force microscopy (AFM) techniques. Photocatalytic dye degradation studies were conducted using methylene blue under ultraviolet light irradiation. Dye degradation ability for nanocubes was found to be superior to the spheres and the rods and can be attributed to the observed high surface area of nanocubes. As-synthesized titania nanostructures have shown higher photocatalytic activity than the commercial photocatalyst Degussa P25 TiO2
Purified cellulose, soybean hulls and citrus pulp as a source of fiber for weaned piglets
Dietary fiber is an important component, which has a direct effect on intake, digestion, and absorption of nutrients; and also alters intestinal microbiota and morphology according to solubility. One digestibility trial and one performance experiment were performed to evaluate the effects of sources of fiber in diets for 21 day weaned piglets. The experimental diets used in both trials consisted of a control diet and diets with purified cellulose, soybean hulls or citrus pulp as a main source of dietary fiber. To evaluate the digestibility of nutrients (Assay 1), the total feces and urine collection method was used. The fiber sources did not affect nutrient digestibility, except for soluble fiber, which increased with the inclusion of citrus (Citrus sinensisL.) pulp. To evaluate performance, morphophysiology and microbiology of the digestive tract of weaned piglets, a total of 32 castrated male piglets was used. Slaughter of animals was implemented at 35 and 50 days of age. The use of soybean (Glycine max L.) hulls and citrus pulp in diets increased the number of goblet cells and the density of villi in the jejunum. The viscosities of stomach and cecum contents increased due to the addition of citrus pulp. Soybean hulls and the citrus pulp included in diets reduced the occurrence of E. coli in the small intestines of piglets slaughtered at 35 days of age. Among the fiber sources, purified cellulose in piglet diets promotes better performance of animals, due to the modulation of the small intestine microbiota, with lower E. coli occurrence resulting in higher villus density
Performance Analysis of Lte Network Using Runtime Pre-coding Algorithm
LTE (Long Term Evolution) meets the requirement of high data rates, improved end user performance, better spectrum utilization, no interference and many more. All this is possible because of its features, one of which is multipoint transmission with single user as well as multi user. But whenever user receives signal from number of transmitting a points, it becomes difficult to calculate the precoders and corresponding filters. The paper describes one of such scenario where user receives signal from multiple eNodeBs. We have implemented a runtime algorithm to estimate the pre-coders and its corresponding filters for system level simulation of LTE network using Matlab
Designing Of Temperature & Humidity Monitoring Embedded Systems
The places such as weather forecasting system, nuclear radiation measurement, greenhouses, agro-automation systems require real-time monitoring of environmental parameters like temperature and humidity. So a low-cost, low-power temperature and humidity sensor interfacing with embedded systems using PIC microcontroller and PLC is designed. The paper is analyzing the operating mechanism of DHT11 temperature and humidity combined sensor; where it features temperature and humidity sensor complex with calibrated digital signal output. The DHT11 sensor interfacing with controller is programmed, then the temperature and humidity acquisition program porting to embedded platform. Meanwhile, the data through human machine interface is intuitive feedback to the user
