The plug-in hybrid electric vehicle (PHEV), utilizing more battery power, has become the next-generation HEV with great promise of higher fuel economy. Global optimization charge-depletion power management would be desirable. However, this has so far been hampered due the a priori nature of the trip information and the almost prohibitive computational cost of global optimization techniques such...

This study investigates replication strategies for reducing latency to desired content in a vehicular peer-to-peer network. We provide a general constrained optimization formulation for efficient replication and study it via analysis and simulations employing a discrete random walk mobility model for the vehicles. Our solution space comprises of a family of popularity based replication schemes ...

The hours of service regulations of the department of transportation severely restrict the set of feasible driver schedules. So much so that establishing whether a sequence of full truckload transportation requests, each with a dispatch window at the origin, can feasibly be executed by a driver is no longer a matter of simple forward simulation. We consider this problem and prove that the feasi...

The Design Automation and Test in Europe (DATE) conference is the main European event in the field of Computer Aided Design (CAD) and testing. This outstanding event brings together researchers, users and vendors, as well as specialists in the design, test and manufacturing of electronic circuits and systems. DATE is a unification of the main conferences in the field and was built on the succes...

The advancements of GPS and GIS technologies provide new opportunities for investigating vehicle trip generation and destination choice at the microscopic level. This research models how land use and road network structure influence non-work, non-home vehicle trip generation and non-work destination choice in the context of trip chains, using the in-vehicle GPS travel data in the Minneapolis-St...

BACKGROUND Translating research evidence into clinical practice (TRIP) is an important initiative for health services so that care delivered is cost-effective, is efficient, and improves patient outcomes. Most TRIP studies have reported on disseminating and implementing clinical practice guidelines, protocols, or care pathways and have been undertaken in acute rather than community settings. ...

We present a constraint programming formulation for the elevator trip origin-destination matrix estimation problem, and study different deterministic and randomized algorithms to solve the problem. An elevator trip consists of successive stops in one direction of travel with passengers inside the elevator. It can be defined as a directed network, where the nodes correspond to the stops on the t...
