INDIVIDUAL TREE PARAMETERS ESTIMATION FOR CHINESE FIR (CUNNINGHAMIA LANCEOLATE (LAMB.) HOOK) PLANTATIONS OF SOUTH CHINA USING UAV OBLIQUE PHOTOGRAPHY: POSSIBILITIES AND CHALLENGES

Chinese fir (Cunninghamia lanceolate (Lamb.) Hook) individual tree parameters extraction is important for scientific forest management.However, high-precision parameters extraction by field investigation or spaceborne optical remote sensing is difficult when the forest is dense and the terrain is complex.This article proposes a framework for extrac

The ability of Synthetic Aperture Radar (SAR) Sentinel-1 data to detect the main wheat phenological phases was investigated in the Bekaa plain of Lebanon.Accordingly, the temporal variation of Riding Trouser Jean Sentinel-1 (S1) signal was analyzed as a function of the phenological phases’ dates observed in situ (germination; heading and soft

Abstract Background The prognostic benefits and safety of extended lymphadenectomy for hilar cholangiocarcinoma remain uncertain.The available evidence is still insufficient concerning its retrospective aspect.The aim of this study is to explore the clinical effect and safety of extended lymphadenectomy compared to regional lymphadenectomy in patie

A method for detecting excitations leading to the damage of the gears and bearings working surfaces has been developed by means of experimental study of the dynamic characteristics of the metro tunnel escalator drive gearbox in normal and bad performance.The technique Adjustable Shock is based on the acquisition and analysis of low and high resolut

Penyerbukan merupakan bagian penting dalam peningkatan produksi tanaman.Salah satu serangga yang bertindak sebagai pollinator pada tanaman adalah lebah galo-galo.Budidaya lebah tanpa sengat dapat membantu proses penyerbukan serta berperan sebagai penghasil madu murni yang juga berpotensi meningkatkan pendapatan petani.Tujuan dari kegiatan ini adala
