Unmanned aerial vehicles, especially agricultural unmanned helicopters (AUH), are nowadays extensively used in precision agriculture.AUHs have recently become responsible for spraying fertilizers and pesticides for crop yields.The strong downward rotating flow produced by the main rotor helps very uniform crop spraying which determines that how imp
More and more devices are equipped with global positioning system (GPS).However, those handheld devices with consumer-grade GPS receivers usually have low accuracy in positioning.A position correction algorithm is therefore useful in this case.In this paper, we proposed an evolutionary computation based technique to generate a correction function b
Developments in selection and emergence of new varieties and hybrids of oilseeds, which have a better ratio of the fatty acid composition of the oil, make is possible to promote such types of crops as camelina, colza, rapeseed and others.The paper presents an analysis of the quality of new and promising varieties and Outdoor Lounge Chair hybrids of
Abstract Background Cassava (Manihot esculenta, Crantz), is a staple food and the main source of calories for many populations in Africa, but the plant is beset by several damaging viruses.So far, eight families of virus infecting cassava have been identified; the Geminiviridae (ssDNA viruses responsible for cassava mosaic disease, CMD) and Potyvir
During retrovirus particle maturation, the assembled Gag polyprotein is cleaved by the viral protease into matrix (MA), capsid (CA), and nucleocapsid (NC) proteins.To form the mature viral capsid, CA rearranges, resulting in a lattice composed of hexameric and pentameric CA units.Recent structural studies of assembled HIV-1 CA revealed several inte
