Article history: Received 4 October 2007 Received in revised form 11 August 2008 Accepted 11 November 2008 Available online 24 November 2008 This paper develops a count data model for credit scoring which allows the estimation of default probabilities using incomplete contracts data. The main advantage of the proposed approach is that it permits a more efficient use of the data, including that ...

The primary objective of a gravity survey over a sedimentary basin is to delineate the shape of the basin. To fulfill this objective, information is needed about the densities within the sedimentary section. Densities of sedimentary rocks increase with depth (mainly due to compaction), approaching that of the basement in deep basins. Sedimentary basins are generally associated with low gravity ...

We propose a secure data aggregation (SDA) framework for mobile sensor networks whose topology changes dynamically with time. The SDA framework (designed to be resilient to both insider and outsider attacks) comprises of a pair-wise key establishment mechanism run along the edges of a data gathering tree and a distributed trust evaluation model that is tightly integrated with the data aggregati...

Multicast content delivery can be expected to become a major source of revenue with the increase of private broadband fixed and mobile communications. Several multicast applications require the receivers to securely send some real-time information back to the source, which leads to a many-to-one communication scenario. Using unicast connections to send this reverse traffic results in a data imp...

Increased drone proliferation in civilian and professional settings has created new threat vectors for airports national infrastructures. The economic damage a single major airport from incursions is estimated to be millions per day. Due the lack of balanced representation data, training accurate deep learning detection algorithms under scarce data an open challenge. Existing methods largely re...

Statistical analysis is an integral part of medical research. It helps transform raw data into meaningful insights, supports hypothesis testing, optimises study design, assesses risk and prognosis, facilitates evidence-based decision-making. The statistical increases research findings' reliability, validity generalisability, ultimately advancing knowledge improving patient care. Without it, the...
