Over the years, the development of artificial intelligence has influenced the fact that the algorithms applied in video devices are renewed every day in their object detection area, such as pattern recognition for detecting an object, image, person. This ... see more

Among the technological evolution is the application of algorithms in cameras for the detection and recognition of people, being a contribution to the security and surveillance in commercial, home areas, and smart cities. The objective of this research is... see more

This paper describes a topical problem of tactical radio system necessary radiocamouflage level support. An intelligence accessibility was proposed like index of radio station and tactical radiosystem radiocamouflage level. The index consist of ... see more

Cognitive Radio Networks (CRNs) have been conceived to improve the efficiency of accessing the spectrum. However, these networks are prone to various kinds of attacks and failures that can compromise the security and performance of their users. One of the... see more

This research has the objective to validate the effectiveness in the execution of the algorithm based on the detection of the image of a person, applied as a control in a lighting device, for better surveillance and energy efficiency in domestic and busin... see more

In this paper, we focus on cooperative spectrum sensing (CSS) for double threshold improved energy detector. In this method, the improved energy detector compares positive power operation p of the amplitude of received signals at each secondary user (SU) ... see more

The general objective of the present work is to contribute to a set up of an operational prototype of monitoring surface energy fluxes inside the Niger’s W Park, using Landsat data and few fields’ data. The model SEBAL/METRIC is used to estimate the main ... see more

Cognitive radio (CR) is a wireless technology developed to improve the usage in the spectrum frequency. Energy consumption is considered as a big problem in this technology, especially during a spectrum sensing. In this paper, we propose an algorithm to i... see more

Concern about everything related to energy is increasingly latent in the world and therefore the use of energy saving concepts has been increasing over the past several years. The interest in the subject has allowed a conceptual evolution in the scientifi... see more
