Use of a panel method in the prediction of external store separation

Author: Van Den Broek, GJ Date: May 1984 A computer program, developed to predict the separation characteristics of external stores after release from the carrier aircraft, is discussed The aircraft is represented by panel singularity distributions along the line of Woodward's USSAERO ... Read more
Use of a sedimentological technique for assessing the engineering performance of sands in roads

Author: Paige-Green, P ; Pinard, M Date: Jul 2011 Although sands cover vast areas of southern Africa, their use as road materials in an untreated state has been generally avoided. An investigation into the properties of various sands has indicated, however, that they can be used as subbase ... Read more
Use of agent based simulation for traffic safety assessment

Author: Conradie, Dirk CU ; Ras, H ; Mentz, F Date: Jul 2008 This paper describes the development of an agent based Computational Building Simulation (CBS) tool, termed KRONOS that is being used to work on advanced research questions such as traffic safety assessment and user behaviour in buildings. ...

The use of antenna radiation pattern in node localisation algorithms for wireless sensor networks

Author: Mwila, MK ; Djouani, K ; Kurien, A Date: Aug 2014 Localisation or position determination is one of the most important applications for wireless sensor networks since the locations of the sensor nodes are critical to both network operations and most application level tasks. Numerous techniques ... Read more
The use of area covered by blood vessels in fundus images to detect glaucoma

Author: Oluwatobi, JA ; Nelwamondo, Fulufhelo V ; Mabuza-Hocquet, Gugulethu P Date: Dec 2019 Several techniques have been employed to detect glaucoma from optic discs. Some techniques involve the use of the optic cup-to-disc ratio (CDR) while others use the neuro-retinal rim width of the optic disc. In this work, we use the area ... Read more
Use of augmented reality in command and control situation awareness

Author: Le Roux, WH Date: Jun 2010 Augmented reality is not completely new technology, but rather an interesting combination of existing technologies, facilitated by the rapid progress made on ultra-portable devices such as smart cellular telephones. It has the potential to ... Read more
Use of biological activities to monitor the removal of fuel contaminants - perspective for monitoring hydrocarbon contamination: A review

Author: Maila, MP ; Cloete, TE Date: Jan 2005 Soil biological activities are vital for the restoration of soil contaminated with hydrocarbons. Their role includes the biotransformation of petroleum compounds into harmless compounds. In this paper, the use of biological activities as ... Read more
