This paper presents additional results of the generalized bathtub model for urban networks, including a simpler derivation and exact solutions uniformly distributed trip lengths. It is shown that in steady state this trip-based equivalent to more parsimonious accumulation-based model, trip-length distribution has merely transient effect on traffic dynamics, which converge same point macroscopic...

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...

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...

The primary objective of the National Airspace System (NAS) is the transportation of passengers and cargo. Since passenger trip time performance is positively correlated with passenger satisfaction, airfare elasticity, and airline profits, it follows that the National Air Space (NAS) performance evaluation, modernization, and consumer protection should be based on passenger trip performance. Pu...

In contrast to white adipose tissue, brown adipose tissue (BAT) is known to play critical roles for both basal and inducible energy expenditure. Obesity is associated with reduction of BAT function; however, it is not well understood how obesity promotes BAT dysfunction, especially at the molecular level. Here we show that the transcription regulator TRIP-Br2 mediates ER stress-induced inhibiti...
