BACKGROUND Road Traffic Crashes (RTCs) are major causes of morbidity and mortality in Nigeria. Few studies in Ibadan have focused on the distribution and determinants of RTC among long distance drivers. OBJECTIVE To describe the distribution of crashes by place, times of occurrence, characteristics of persons involved and identify associated factors. METHODS A cross-sectional study was carr...

We introduce the powerful, flexible and efficient nonparametric Classification and Regression Trees (CART) algorithm to the analysis of mortgage default data while conducting the first academic study of mortgage default in Israel. CART’s strengths in dealing with large data sets, high dimensionality, mixed data types, missing data, different relationships between variables in different parts of...

The integrity of data stored on a hard disk is typically verified by computing the chained hash value of disk sector data in a specific order. However, this technique fails when one or more sectors turn bad during storage, making it impossible to compute their hash values. This paper presents a k-dimension hashing scheme, which computes and stores multiple hash values for each hard disk sector....

The area-wide installation of smart meters in low voltage (LV) grids prospectively provides information about the relevant operational system parameters, e.g. complex node voltages and line loads. Under the condition of neglected house to grid connection lines, a positive local measurement redundancy at every network node is obtainable. In general, this enables the implementation of special thr...

Most approaches to iterated belief revision are accompanied by some motivation for the use of the proposed revision operator (or family of operators), and typically encode enough information for uniquely determining one-step revision. But in those approaches describing a family of operators, there is usually little indication of how to proceed uniquely after the first revision step. In this pap...
