Performance of a Neural Network Classifier Based Demodulator in Communication System by Anand Kumar

“…Low SNR are common in spectrum sensing, cognitive radio networks, underwater acoustics, target detection, remote sensing, seismic monitoring, and helicopter blade detection. This classifier-demodulator performance was compared with that of the matched filter detector (MFD) for varying channel noise, constellation type (PSK or QAM), constellation size (M=2, 4, 8, 16), sample size (N), and training to test the data ratio. …”

Geometry by Design: Contribution of Lidar to the Understanding of Settlement Patterns of the Mound Villages in SW Amazonia by Jose Iriarte, Mark Robinson, Jonas de Souza, Antonia Damasceno, Franciele da Silva, Francisco Nakahara, Alceu Ranzi, Luiz Aragao

“…To address these shortcomings, we carried out the first Lidar survey with a RIEGL VUX-1 UAV Lidar sensor integrated into an MD 500 helicopter. Our novel results documented distinctive architectural features of Circular Mound Villages such as the presence of ranked, paired, cardinally oriented, sunken roads interconnecting villages, the occurrence of a diversity of mound shapes within sites, as well as the exposure the superimposition of villages. …”

Gypsy Moth Management with LdMNPV Baculovirus in Cork Oak Forest by Luca Ruiu, Roberto Mannu, Maurizio Olivieri, Andrea Lentini

“…Due to an observed retrogradation phase of the target pest in 2019, no significant differences in larval density between areas treated from a helicopter and control were detected, but in the few weeks following application, a meaningful vitality decrease in larval samples from treated plots was observed. (5) Conclusions: Based on the results of this study, the use of LdMNPV in forest protection programs against gypsy moth can be worth consideration in multi-year integrated program strategies to modulate population dynamics.…”

An investigation on tapered wings with leading edge tubercles by Zhang, Yongjie

“…The designs of the blades mimicked the actual rotor blades that were used in a UH-1H Bell helicopter. In total, 4 configurations of rotor blades were designed using Solid Works, one with straight leading edge, and the 3 others with varying amplitudes(A) and wavelength(λ) for the leading edge protuberances, (A=0.05c λ = 0.25c, A=0.15c λ = 0.25c, A=0.05c λ = 0.125c). …”
