Since reinforced concrete (RC) buildings have long service life, cutout openings are generally needed in their load-bearing walls as a sustainable solution order to meet new requirements of users. However, the decrease capacity walls, which may result failure buildings. In this paper, we investigate possibility making door opening RC wall an existing building Gävle Sweden. The studied current p...

Identification of the last effective boll population allows informed decisions for termination of insecticide and application of harvest aids. However, the current COTMAN cutout reference, i.e., NAWF=5 (Oosterhuis et al., 1999), may need to be changed for ultra-narrow-row (UNR) cotton. This study is part of a multi-state project which has an overall objective of determining the main-stem node n...

We propose a novel personal identification method, named Thermal-ID, which utilizes human body temperature as a source of identifying information. Thermal-ID is expressed by the temperature difference generated by partially covering the surface of the body with thermal barrier material (e.g., cutout urethane foam-coated aluminum foil). The aim is to positively identify a subject with minimal di...

We present the computation of envelopes of a set of quadratic surfaces defined in IR. Our solution is based on the new Cgal Envelope 3 package that provides a generic and robust implementation of a divideand-conquer algorithm. This work concentrates on the theory of algebraic and combinatorial tasks that occur for quadratic surfaces and their implementation. The implementation is exact and effi...
