Autonomous landing is an essential function for micro air vehicles (MAVs) for many scenarios. We pursue an active perception strategy that enables MAVs with limited onboard sensing and processing capabilities to concurrently assess feasible rooftop landing sites with a vision-based perception system while generating trajectories that balance continued landing site assessment and the requirement...

In the present work, a 5-kW hybrid PV solar system was installed on roof of house in Diyala, Iraq (33.77° N, 45.14° E elevation 44 m). The consists two strings, where each string nine polycrystalline modules with 355 Wp series, and strings are parallel. energy storage (ESS) parallel four 12 V 150 Ah tubular deep cycle batteries series. A inverter 5 kW rated power operated different modes. resul...

Solar photovoltaic (PV) systems are used worldwide for clean production of electricity. Photovoltaic simulation tool serve to predict the amount energy generated by PV solar array structure. This paper presents system installed on rooftop G.D. Naidu Block at Vellore Institute Technology (Vellore, India). A novel plant design is developed here in order improve energetic efficiency an existing sy...

In fixed-to-fixed channel, it is widely assumed that the channel is stationary in time for above rooftop LOS propagation. This assumption is based on the fact that surrounding buildings are the main cause of multipath fading. However, the channel become quasi-stationary in time especially at lower receiving height (below rooftop) and for cases where moving objects are in the vicinity of receivi...

A ray-tracing algorithm is used to simulate broadband radio propagation at 3.5GHz for a FWA network in a high-rise city environment. Both coverage and uplink interference are investigated, with linear antenna polarisation. It is shown that some rooftop locations are unsuitable positions for SU’s, due to the existence of single or multiple-bounce reflected rays causing uplink interference. It is...

Due to the effects of climate change and the increasing demand on water, sustainable development in term of water resources management has become a major challenge. In this context, the application of simulation models is useful to duel with the uncertainty and complexity of water system by providing stakeholders with the best solution. This paper outlines an integrated management planning netw...
