We here show how evaporation/condensation processes lead to efficient heat spreading along a liquid/gas interface, thereby damping thermal fluctuations and hindering thermocapillary flows. This mechanism acts as an effective thermal conductivity of the gas phase, which is shown to diverge when the latter is made of pure vapor. Our simple (fitting-parameter–free) theory nicely agrees with measur...

Probabilistic logics are commonly designed by adding probabilistic operators and their semantics to a logical system. There are several axes in which one might classify probabilistic logics, depending on syntactic and semantic design decisions. By using classical propositional logic as a starting ground, the present work aims at shedding some light on which choices are relevant when classifying...

We report measurements of the specific heat of He-He mixtures near the superfluid transition when confined to channels of 1 μm square cross section. These data test the universality of finite-size scaling as function of He concentration for 1D crossover. The analysis of these data requires that data measured at fixed concentration be converted to a specific heat at constant chemical potential d...

As part of the Challenge X competition, the University of Tennessee has chosen a hybrid electric powertrain architecture for conversion of a 2005 Chevrolet Equinox SUV to a more fuel efficient and environmentally responsible vehicle. A brief overview of the powertrain configuration is presented, as well as the corresponding supervisory control system architecture. The methodology for developing...

This paper proposes TONAK, an AWGR-based optical switch with distributed control plane. Simulations results for a 128-port switch show high throughput and low average packet latency for offered loads of up to 75%, while achieving an energy efficiency of ≈ 50pJ/bit. Introduction The ever-growing demand for cloud-based services and high-performance computing is posing major challenges to the scal...

The Center for Transportation Research (CTR) Vehicle Systems team modified a Nissan CK-2 Continuously Variable Transmission (CVT) for a diesel hybrid powertrain application. Mechanical and electrical modifications were made to the CVT, both internal and external to the transmission. The goal of this experiment was to investigate and demonstrate the potential of CVT for diesel engines hybrid ele...

In two experiments a self-regulatory strategy combining mental contrasting with the formation of implementation intentions (MCII) was tested for its effectiveness in diminishing unhealthy snacking habits. Study 1 (N1⁄4 51) showed that participants in the MCII condition consumed fewer unhealthy snacks than participants in a control condition who thought about and listed healthy options for snack...
