Models that describe the processes by which drivers follow each other in the traffic stream are generally referred to as car-following models. During the past 50 years, driver behavior within the traffic stream has been studied and models that attempt to describe this behavior have been proposed. Car-following models have frequently been developed for the purpose of incorporation with microscop...

Each day, CSX Railway allocates hundreds of empty railcars among hundreds of customer car orders. In 1997, it implemented the US rail industry’s first real-time, fully integrated equipment-distribution optimization system, the dynamic car-planning system (DCP). DCP seamlessly integrates operations research modeling into CSX’s process that assigns empty cars to customer car orders. CSX estimates...

The effectiveness of small microphone arrays for in car use is investigated. These arrays are designed for speech enhancing at noise background within the cabin of a moving car. Speech and noise simulation based on designed mathematical algorithm of sound field modeling within a car cavity is applied for predicting effectiveness of the spatial-time processing algorithms. The mathematical model ...

The nuclear receptor CAR (NR1I3) regulates transcription of genes encoding xenobiotic- and steroid-metabolizing enzymes. Regulatory processes that are mediated by CAR are modulated by a structurally diverse array of chemicals including common pharmaceutical and environmental agents. Here we describe four in-frame splice variants of the human CAR receptor gene. The variant mRNA splice transcript...

This paper uses simple game theory to analyze a situation where two agents compete in the transport market. The modeling frame is that of a mode choice model, where the two mode options are boat or car transportation. The basic findings are that non pareto optimal (car, car) equilibrium outcomes, may occur in a surprisingly large amount of cases. Additionally, the possible different Nash equili...

This study was inspired by the unique multi-scale and multi-level 'brick-and-mortar' (B&M) structure of nacre layers. We prepared the B&M, environmentally-friendly graphene oxide-carrageenan (GO-Car) nanocomposite films using the following steps. A natural polyhydroxy polymer, carrageenan, was absorbed on the surface of monolayer GO nanosheets through hydrogen-bond interactions. Followi...

This article proposes the 7 C’s for realizing quality-oriented software engineering practices. All the desired qualities of this approach are expressed in short by the term living software. The 7 C’s are: Concern-oriented processes, Canonical models, Composable models, Certifiable models, Constructible models, Closure property of models and Controllable models. Each C is explained by the help o...

This paper presents a computational modeling approach for negative effects simulation of visual distraction while driving a car. In order to investigate these effects, an experiment was firstly implemented on a driving simulator. Twenty participants were invited to perform a car following task in different driving conditions (12 driving scenarios), with or without a secondary task of visual dis...

Systems of systems such as Smart Ecosystems, Cyber-Physical Systems, and the Internet of Things support flexible collaborations among heterogeneous participants with open interfaces. To assure safety in all possible collaboration scenarios, we introduced in previous work the ConSerts approach. This approach assumes that system interactions are captured via required and provided services. Consid...
