New algorithms for image analysis, compression, and 2-D spectrum estimation in the radon space
… The theory suggests a new approach to 2-D spectrum estimation using the Radon transform, which is considered in the sequel. Some of the issues associated with the Radon transform of a stationary random field are brought out. A new representation for the Radon transform of a stationary …

Deployment Policies to Reliably Maintain and Maximize Expected Coverage in a Wireless Sensor Network
… periodic time intervals. The network destruction spectrum (D-spectrum) has been introduced to estimate reliability and is more commonly applied to a static network, rather than a dynamic network where new sensors are deployed over time. We discuss how the D-spectrum can be incorporated to estimate …

Mathematical frameworks for quantitative network analysis
… measures on graph vertices. The concept of a D-spectrum is introduced, based on vertex ranks within certain chains of nested sub-graphs. We show that the D- spectrum integrates the degree distribution and coreness information of the graph as two particular such chains. We prove that these …

Finite fraction method for tracking desinfection by-product precursors in water treatment
… fluoresces uniquely in certain region of the 3-D spectrum, (2) the fraction identification was a function of the fluorescent intensity, the slope of fluorescence peak and the area under the peak spectrum. In fact, it was found that the product of the spectral slope and the spectral area …

Identifying Children with Constitutional Mismatch Repair Deficiency (CMMR-D) Syndrome in the Expanding Lynch Syndrome population in Cape Town
… repair (MMR) genes that result in a tumour spectrum including colorectal cancers, high-grade gliomas, non-Hodgkin T-cell lymphomas and leukaemias. It is characterized by biallelic germline mutation of one of four possible MMR genes resulting in loss of protein expression that can be …

Defect characterization in concrete elements using vibration analysis and imaging
… effects of the IE test setup on the frequency spectrum are discussed, and limitations in the application of the IE test are pointed out. Finally, some strategies for practical application of air-coupled IE tests are recommended for future complimentary work efforts.
