Data collection framework for vehicular On-Board-Diagnostic systems
Most modern vehicles contain an On-Board-Diagnostic (OBD) system that can collect a wide range of system data from the vehicle. In aggregation, such data could be applied towards solving the problems of accident prevention, vehicular safety, and driving efficiency. In this paper, we describe our …

Error patterns: what do they tell us?
An analysis of computer diagnostic systems shows that most systems use answer data (product) for their analyses. This process of determining an error pattern, in addition, does little in the way of telling a teacher what should be done to help the child. This two-fold problem, extant in all …

Feature-Based Neuro-Symbolic Networks for Global Diagnostics
<p>Engineered system diagnostics have been researched over the years with many successful results. From transportation systems to office technologies, many have been equipped with self-diagnostic capabilities and are called Smart Machines. In spite of these advances, current diagnostic systems are …

Charge transfer at thin-film modified solid-liquid interfaces in the absence of redox-active moieties
Advanced diagnostic systems that are capable of the early detection and the narrow therapeutic targeting of diseases represent the future for modern medicine. The development of highly sensitive, single molecule detection technologies with high throughput capabilities is a prerequisite to the large …
