Abstract null null (FSO) Frees Space Optical communication is considered one of the communication systems types which uses light to carry the data between transmitter and receiver. It is previously known that the system which uses single input single output (SISO) technique is suffered from high rate of attenuation due to obstacles and various conditions of weather. The impacts of weather conditions which influence on the performance of the overall FSO communication system. Wavelength division m...

Abstract null null At the present, many medical and military institutions need to transmit data reliably and accurately; thus, any impact on the signal leads to a change of information and affects the patient’s life at the health level or confidential information in the case of military institutions. In this paper, we tested low-frequency signals represented by electroencephalography (EEG) and speech signals; these signals transmitted through the OFDM system. The transmitted signal affected by n...

Abstract null null A technique for the recognition of motor license plates via vehicle image analysis was presented in this article. The process involves accurate recognition of the license plate location, followed by extraction of the characters of the plate number. Plate edge recognition was performed using morphology algorithms that transformed and adjusted different viewing angles of the license plate, while a histogram-based approach was used to extract the characters. The extracted charact...

Abstract null null This paper introduces the design as well as modelling of a multiband planar antenna based on fractal shapes. Sierpinski carpet as well as Minkowski fractal geometries are applied to a square shaped patch antenna. The result from this combination is multiband, small size, high gain as well as low return loss antenna. The proposed antenna cover multi-frequency bands such as, 3.4, 4.03, 5.8, 6.48, 6.78, 7.32, 8.26, 9.21, 10.09 GHz. Antenna parameters as well as performance have b...

Wireless telecommunications systems have expanded rapidly over the past few years. Wireless Body Sensor Network (WBSN) is a relatively novel area of research and development in healthcare systems. However, it has multiple constraints and challenges regarding human health, social interactions, coverage radius, energy consumption, and communication reliability. In addition, communications between nodes can contain highly sensitive personal information, while hostile environments will impose a wide...

The security strengths of block ciphers greatly rely on the confusion components which have the tendency to transform the data nonlinearly into the perplexed form. This paper proposes to put forward a novel scheme of generating cryptographically strong nonlinear confusion components of block ciphers, usually termed as substitution-boxes (S-boxes). The anticipated S-box design scheme is based on a novel five-dimensional (5-D) chaotic system analyzed in this paper. The proposed 5-D dynamical syste...

Diabetes Mellitus is a chronic disease that spreads quickly worldwide. It results from increasing the blood glucose level and causes complications in the heart, kidney, and eyes. Diabetic Retinopathy (DR) is an eye disease that refers to the bursting of blood vessels in the retina as Diabetes exacerbates. It is considered the main reason for blindness because it appears without showing any symptoms in the primitive stages. Earlier detection and classification of DR cases is a crucial step toward...
