UAV trajectory optimisation in smart cities using modified A* algorithm combined with Haversine and Vincenty formulas

It is anticipated that the backbone of Smart Cities concerning automation and networking will be formed by Unmanned Aerial Vehicles in the imminent future. Therefore, our research focuses on developing advanced microcontrollers embedded with Artificial Intelligence techniques for self-governing Unmanned Aerial Vehicles. The main objective of this research was to enable full automation for the execution of flight paths with non-trivial sequences that will be performed with centimetre-level accuracy. Also, by utilising dynamic flight plans and trajectories, we aim to secure autonomous aviation based on norms, with control loops and fundamental constraints. More specifically, we evolved a novel algorithmic technique for trajectory optimisation, which deploys a modification to the A* search algorithm, implemented by the Haversine formula and enhances accuracy using Vincenty’s formula. Furthermore, realistic values for trajectory optimisation and obstacle avoidance were found through the implementation of a simulative investigation. The outcomes of our methodology indicate that the safety constraints associated with the integration of Unmanned Aerial Vehicles in the urban environment can be significantly mitigated. Consequently, their effectiveness will be increased in realising their diverse operations and capabilities

On some Megachilidae (Hym. Apoidea) from Spain and Morocco

The following records, descriptions and notes were based on a material of Megachilid bees collected bv Dr. José M. a Dusmet, Madrid, from the continental Spain, and by Mr. Anselmo Pardo Alcaide, Melilla, from Spanish Morocco. I am greatly indebted to the above-said colleagues for their kind assistance, as well as, to the authorities Instituto Español de Entomología, Madrid, for sending me the type of Anthidium astilleroi Dusmet and A nthidium eloederleini dusmeti subsp. nov., for studv.Peer reviewe

On the bees (Hymenoptera, apoidea) of Siria: part I

Número enero-diciembreSyria has been considered by many previous authors as the extensive territory covering the whole States of Lebanon, Syria, Israel and a large part of Jordan. In this paper I treat the bees of Syria as it is limited politically between Lebanon, Israel, Jordan, Asiatic Turkey and Iraq.Peer reviewe
