Integrating electrophysiological signal in larger systems is getting wider due to the fact that such modalities facilitate the daily tasks of users. However, the high cost of monitoring systems (e.g., oscilloscopes) limits the testing and the analysis of acquired signal from such noisy systems (i.e. electrophysiological devices). The proposed syste...

Bio-Robotics is an innovative field that helps in improving the quality of life of people with special needs. People who suffer from hands related inability or immobility encounter many problems in their life. Eating, a basic necessity is a troublesome task that negatively impacts these people. Their inability to easily feed themselves may lead to...

Although technology has been evolving rapidly in this information age, deaf/mute people still use sign language as their only way of communication. Using sign language as a communication tool can be beneficial among those who are familiar with this language, but the problem remains when communicating with the wider community. Sign Language Translat...

This paper includes a novel technique for "Ethnicity Detection System" via extracting geometric features from pictures, such as the nose width, lips width, forehead width and color. These aforementioned features can be easily extracted by means of the Viola Jones algorithm, followed by the execution of the artificial neural networking. This process...

The implementation of digital musical instruments has been growing in the last few years. The musical domain is relying on the use of electrical musical systems that are still manually controlled by humans. Although the full control of such systems remains more theoretical especially when the melody is not well known and/or saved within this electr...

Modulation is a process through which a message has to pass in order to be effectively transmitted. However, there are some limitations to Pulse Code Modulation and Delta Modulation that can cause data redundancy, quantization error, slope overload distortion and granular noise which result in a bad communication process. Throughout the past few ye...

This paper focuses on the first step of a larger research program. The objective of this step is to model and control the initial part of a wind musical instrument (flute) which is the artificial mouth, for the purpose of precisely controlling the input pressure and the output flow that will be feeding the resonator of the instrument in order to ge...

The objective of this first step is to develop a simulator programmed with MatLab/Simulink in order to help the design of an artificial mouth for wind instruments. Thus, this paper presents the system description and its modelling that leads to the simulator (nonlinear model), then...

This paper introduces a fractional order audio band pass boost filter. The boost filter is part of the equalizer along with the cut filter: the first (e.g. the boost) is a band pass filter whereas the second is a stop band filter. These types of audio filters are widely used for their effectiveness in removing noise and echo. This paper will treat...

In order for a message to be feasible for transmission, it has to pass through an essential process which is “modulation”. Through years, Pulse Code Modulation (PCM), Delta Modulation (DM) and Differential Pulse Code Modulation (DPCM), in digital communication systems, have proven their unlimited advantages over analog communication systems, in ter...
