One important step in binary modeling of environmental problems is the generation absence-datasets that are traditionally generated by random sampling and can undermine quality outputs. To solve this problem, study develops Absence Point Generation (APG) toolbox which a Python-based ArcGIS for automated construction geospatial studies. The APG employs frequency ratio analysis four commonly used...

Machine learning driven image-based controllers allow robotic systems to take intelligent actions based on the visual feedback from their environment. Understanding when these might lead system safety violations is important for integration in safety-critical applications and engineering corrective measures system. Existing methods leverage simulation-based testing (or falsification) find failu...

This study aims to model the motorized two-wheeler (MTW) riders’ evasive-action behavior towards jaywalking pedestrians using a mockup study. The brake reaction times (BRTs), approach speeds, decelerations, headings, and yaw rates were analyzed for two surprise scenarios (scenarios 1 3), one stationary scenario (scenario-2), expected (scenario-4). In total, 50 riders participated in results rev...

important and necessary phase in identifying the public transport system has survey and analysis of system ability in reply to existence demand and determine the its functional characters .the optimal control of a public transport system required to analytic studies for identifying the characteristics of system in before, during and after implementation phases . in this article, the efficiency ...

This paper presents the conception, design, implementation and testing of innovative software architectures and software development processes for rapid prototyping of automated transit buses. Our work is motivated by demonstrations of automated transit bus technology in the context of Bus Rapid Transit (BRT) systems. Mission handling and safety issues are handled via a three-layer hierarchical...

Workloads for high-performance streaming databases often contain many writes of small data blocks (for example, of metadata) followed by large subrange queries. Most of today’s file systems and databases either cannot provide adequate performance for the write phase, the read phase, or both. The supercomputing technologies group at MIT CSAIL has been investigating cache-aware and cache-obliviou...
