This paper aimed at introducing a completely automated Arabic phone recognition system based on Enhanced Wavelet Packets Best Tree Encoding (EWPBTE) 15-point speech feature. The process of enhancing of WPBTE is provided by adding energy component to WPBTE, which is implemented in Matlab software and makes an enhancement of 65 % to recognizer accuracy which is the most contribution in this paper. EWPBTE is used to find phoneme boundaries along speech utterance. Hidden Markov Model (HMM) and Gaussian Mixtures are used for building the statistical models through this research. HMM Tool Kit (HTK) software is utilized for implementation of the model. The System can identify spoken phone at 57.01% recognition rate based on Mel Frequency Cepstral Coefficients (MFCC), 21.07% recognition rate based on WPBTE and 86.23% recognition rate based on EWPBTE. The proposed EWPBTE vector is 15 components compared to 39 components of MFCC. This makes it very promising features vector to be under research and in development phase. � 2016 IEEE.
Enhancement of a GSM based control system
(Research India Publications, 2015) Hassan A.M.A.; Department of Electronics and Communications; October University for Modern Sciences and Arts; 26 July Mehwar Road intersection with Wahat Road; 6 October City; Egypt
This paper presents the development and implementation of a Global System for Mobile Communication (GSM) based on control system for electrical applications that enables the complete control of the interface on which it is based. GSM module was used for receiving short message service (SMS) from user�s mobile phone that automatically enable the controller to take further action like switching ON and OFF electrical applications such as fan, air- conditioner, light etc. The system was integrated with microcontroller and GSM network interface using arduino.orduino software was utilized to accomplish the integration. The system is activated when user sends the SMS to the controller at home (regarded as Smart Home). Upon receiving the SMS command, the microcontroller unit then automatically controls the electrical applications by switching ON or OFF the device according to the user�s order. In other word, it reads message from the mobile phone and respond to control the devices according to the received message. � Research India Publications.
Enhancement of designing the smart glove
(Research India Publications, 2015) Hassan A.M.A.; Department of Electronics and Communications; October University for Modern Sciences and Arts; 26 July Mehwar Road intersection with Wahat Road; 6 October City; Egypt
Voice glove is a system that helps the deaf and dumb people to communicate with normal people without Interpreter. It wants to break that barrier between these people and normal people and helps them to live a normal life. A voice glove was designed to facilitate an easy communication through recorded speech for the benefit of speechless patients. This paper is aimed to improve the designing of the smart glove where the Gestures of fingers of a user for this glove will be converted into a memory address which is used to hit the memory location in which voice message is stored to convey an audible message to others. The glove is internally equipped with multiple flex sensors that are made up of "bend-sensitive resistance elements". For each specific gesture, internal flex sensors produce a proportional change in resistance of various elements. The processing of this information sends a unique set of signals to the PIC Peripheral Interface Controller (PIC) microcontroller which is preprogrammed to speak desired sentences stored in Secure Digital (SD) memory card. � Research India Publications.
Indoor location tracking system using neural network based on bluetooth
(Institute of Electrical and Electronics Engineers Inc., 2016) Hassan A.M.A.; Department of Electronics and Communications Engineering; October University for Modern Sciences and Arts; 6 October City; Egypt
This paper introduces the design and implementation of a Bluetooth based on indoor location tracking system. This system utilizes the integrated Bluetooth modules in any today's mobile phones to specify and display the location of the individuals in a certain building. The proposed system aim for location tracking/monitoring and marketing applications for whom want to locate individuals carrying mobile phones and advertise products and services. It is an integrated embedded and desktop system that helps the user to get the location of customers/inhabitants/employee within a certain region. The system is composed of a Server Module which is a java application that runs over desktop PC and is used to display the locations of the nearby mobile phones and send location based advertising message. This paper is aimed also to enhance the system positioning estimation accuracy by choosing the suitable number of neurons used in the neural network. � 2016 IEEE.
