2015/11/16
With the availability of very high resolution multispectral imagery from sensors such as IKONOS and Quickbird, it is possible to
identify small-scale features in urban environment. Because of the mu...
AN INTERACTIVE TOOL FOR 3D OBJECT EXTRACTION USING AIRBORNE LASERSCANNING DATA AND ORTHOIMAGES
Airborne Laserscanning Orthoimages 3D Object Extraction
2015/9/28
Light Detection And Ranging (LiDAR) provides reliable and detailed 3D data of the earth surface. This data combined with digital
Orthoimages can be used to create detailed 3D object models that are ...

This paper deals about astronomical orientation of Incas objects in Ollantaytambo, which is located about 35 km southeast from Machu Picchu, about 40 km northwest from Cusco, and lies in the Urubamba ...
Not every object in the derived category of a ring is Bousfield equivalent to a module
Not every object derived category ring Bousfield equivalent module
2012/3/1
We consider the derived category of a specific non-Noetherian ring \Lambda, and show that there are objects in D(\Lambda) that are not Bousfield equivalent to any module. This answers a question posed...
