K. Moro, M. Fakir, B. Bouikhalene, R. El Yachi, Bader D. El Kessab: New Approach of Feature Extraction Method Based on the Raw Form and his Skeleton for Gujarati Handwritten Digits using Neural Networks Classifier
Abstract: This paper presents an optical character recognition (OCR) system for Gujarati handwritten digits. One may find so much of work for latin writing, arabic, chines, etc. but Gujarati is a language for which hardly any work is traceable especially for handwritten characters. Here in this work we have proposed a method of feature extraction based on the raw form of the character and his skeleton and we have shown the advantage of using this method over other approaches mentioned in this article.
Keywords: Optical character recognition, neural network, feature extraction, Gujarati handwritten digits, skeletonization, classification.
N. Badea, G. V. Badea: Cogeneration System with Fuel Cell for the Energy Supply of Building
Abstract: This paper proposes a new
solution for the energy supply of buildings using electrochemical power
sources. The paper shows experimental results in using PEM fuel cell for
electricity supply of a gas condensing device. The paper also presents all
the components and monitoring measurements of the electrical and thermal
values for fuel cell. The experimental testing of the influence of power
quality produced by the fuel cell and inverter in boiler operation, leads to
use of inverters with sine wave profile on the electricity supply of
building. Cheap inverters with rectangular wave or rectangular wave modified
by the harmonics content produced, leads to blocking the microprocessor,
removing the boiler operation. The experimental system has 0.72 kilowatt
electrical power of the fuel cell, while the total thermal output power of
the condensing heating device 25 kilowatts . The experimental power quality
results obtained with this supply system are presented in the end of the
paper.
Keywords: cogeneration, energy supply, fuel cell.
N. Marasescu: Determining the Optimal Period for Renewal within Evolutionary Strategies
Abstract: This paper deals with the determination of the optimal period for renewal of the equipment described by a reliability model with constant parameters. For this purpose use is made of an evolutionary strategy based on a Markov reliability model. Markov model parameters are adjusted using an ADALINE-type neural network, a trained network using a sliding window.
Keywords: Reliability, Markov models, diagnosis, neural networks.
M. K. Rafsanjani , M. Riyahi: Study on Instrusion Detection Systems using Genetic Algorithm
Abstract: With the extension in computer networks and appearing new attacks, seems that security is more necessary than before. Intrusion Detection System (IDS) is one of the most important methods to develop security in computer networks. There are different methods for IDS improvement. Machine learning is one of these methods and an approach for improving IDS with machine learning using Genetic Algorithm (GA).
Keywords: Computer networks, Intrusion Detection System, Machine learning, Genetic Algorithm
C. M. Marinescu: Electrical Engineering Guide
Abstract: This paper describes the steps required to form a future electrical engineer. This guide informs what skills a future electrical engineer and what studies need to follow to meet the needs of an employer. This paper explains what educational programs must be completed in order to have a successful career in this field and a salary to match. Engineering is the art of applying scientific and mathematical principles ,experience, judgment, and common sense to make things that benefit people. An electrical engineer is responsible for designing, developing, testing, and supervising the production of electrical equipment and systems, in fields ranging from transportation to lighting and wiring systems to power generation and transmission.
Keywords: electrical engineering, degree, industries, system , solutions, schools.
