Nettet19. mai 2024 · Scenario identification plays an important role in assisting unmanned aerial vehicle (UAV) cognitive communications. Based on the scenario-dependent channel characteristics, a support vector machine (SVM)-based air-to-ground (A2G) scenario identification model is proposed. In the proposed model, the height of the UAV is also … Nettet26. nov. 2013 · The line spread functions are generated by exposing a series of 1-mm slits located in a 3-mm-thick lead plate positioned directly on the detector (NEMA slit phantom). The slits are separated by 30 mm and should be long enough to cover the useful field of view of the gamma camera. ira distribution at death beneficiary tax
