Radio waves-based landslide mitigation system

Effects of radio waves on male fertility

In recent years, male fertility has changed due to the effects of environmental, health and lifestyle factors and the infertility rate has increased, to the extent that male fertility may be affected by extreme heat, exposure to pesticides, radiation, substances Changes in radioactivity, lifestyle, stress and occupation. In the environment, there are ionizing and non-ionizing rays whose effect...

Radio Frequency Interference Mitigation in Radio Astronomy

Radio Waves for Space-Based Construction

This paper follows up on the idea of using potential fields for automatic construction of massive objects of desired shape in Space. In STAIF03, we showed the commonality between the theories for acoustic and optical positioning/shaping methods. Using this theoretical framework, we developed a simple engineering estimation scheme to predict the acceleration per unit intensity. The radiation pre...

Uncertainty area-based interference mitigation for cognitive radio

A new interference mitigation approach is presented for a Mobile Ad Hoc NETwork (MANET), acting as a secondary wireless network, which takes advantage of smart antennas and cognitive radio capabilities when arbitrarily deployed in the same area as a primary wireless network while both sharing the same spectrum. The MANET has to cope with the very coarse probabilistic estimate of the primary net...

X-band Radar Sensor for the Landslide Risk Mitigation

A low cost Stepped Frequency Continuous Wave sensor is proposed in this work as radar module for the long range monitoring of environmental scenarios subject to landslide risk. A radar configuration based on the adoption of a variable scanning antenna array is proposed for the accurate detection of land movements. Furthermore, a X-band radar module prototype is realized and tested to demonstrat...
