Geographic information systems (GIS) now provide accurate maps of terrain, roads, waterways, and building footprints and heights. Aircraft, particularly small unmanned aircraft systems, can exploit additional information such as building roof structure to improve navigation accuracy and safety particularly in urban regions. This paper proposes a method to automatically label building roof shape...

In the title compound, [Zn(2)(C(8)H(7)N(3)OS)(2)(C(5)H(5)N)(2)], the Zn(2)O(2) ring has a flattened roof shape, with the roof angle equal to 10.10 (6)°. The thio-semicarbazones act as tridentate ligands to one Zn(II) atom, with the O atoms additionally in bridging positions to the second Zn(II) atom. Both Zn(II) atoms are five-coordinated; the coordination polyhedra are close to square pyramids...

introduction controlling greenhouse microclimate not only influences the growth of plants, but also is critical in the spread of diseases inside the greenhouse. the microclimate parameters were inside air, greenhouse roof and soil temperature, relative humidity and solar radiation intensity. predicting the microclimate conditions inside a greenhouse and enabling the use of automatic control sys...

Abstract Funding Acknowledgements Type of funding sources: None. Background Atrial tachycardia (AT) is a commonly encountered rhythm disorder in patients with underlying atrial scar. The role late potential (LP) based mapping the detection AT critical isthmus has yet to be systematically evaluated. Purpose We aimed investigate relationship between LPs (ALP) localization sinus and re-entrant ATs...

Automatic building reconstruction from LIDAR data has become a hot topic for several years. Many methods and algorithms have been put forward to reconstruct the building models, such as of flat roof, gable roof, or other rectangular shapes. Among which, contour based method is an innovative one to simplify the focusing, detection and reconstruction of buildings. In this paper, the contour clust...

Selecting the incorrect control during the operation of underground bolting and drilling equipment causes serious injuries. Shape coding and the layout of dual control banks are two aspects of control design which require further examination. The aims of this research were: (i) to determine whether arbitrary shape coding was effective in reducing selection error rates in a virtual analogy of ro...

Solar energy is a new renewable energy. Using solar to generate electricity an effective means achieve sustainable development. The huge roof at the top of airport natural interface receive energy, which can be used supply needed by through building integrated photovoltaic design. However, due curved shape roof, there are limitations in acquisition and construction roof. In this paper, method “...

A roof provides protection to be safe from direct sunlight. From the shelter, shadow alone is not expected. Durability, sustainability, less life cycle cost, and low maintenance cost are expected from a selected roof. The world has a thirst to have a best roof. No roof will fulfil the requirement of humanity since the climatic conditions are different. Hence the roof should be selected accordin...
