The experimental analysis of the electrical behavior of Phase Change Memory arrays evidenced a seasoning effect both on SET and RESET state. The previous modeling efforts on this issue were addressed only towards RESET operation. This work presents a SET seasoning model implemented within a numerical simulator starting from the extraction of the characteristic erase operation kinetic parameters...

To quantify the effects of recent and potential future decreases in surface wind speeds on lake thermal stratification, we apply the one-dimensional process-based model MyLake to a large, shallow, polymictic lake, Võrtsjärv. The model is validated for a 3-year period and run separately for 28 years using long-term daily atmospheric forcing data from a nearby meteorological station. Model simula...

Long-term trends in the mesosphere, thermosphere, and ionosphere are areas of research of increasing importance both because they are sensitive indicators of climatic change and because they affect satellite-based technologies which are increasingly important to modern life. Their study was an important part of CAWSES-II project, as they were a topic of Task Group 2 (TG-2) ‘How Will Geospace Re...

31 Climate models are essential tools for assessing future climate change. In making predictions, it 32 is beneficial to examine simulations from various models that are developed at centers around the 33 world. The simple average over an ensemble of such models is often taken as the optimal 34 prediction, which in studies of current climate is demonstrated as being more accurate than 35 relyin...

Simulations of world history, like the real thing, are complex systems whose outcomes most often (if not always) constitute highly contingent events. Rarely (if ever) will researchers be able to find unqualified main effects that explain important outcome measures that affect the security and prosperity of the world community. The problem of contingency for testing hypotheses about the causes o...

This paper introduces a solution for the fair division of emission reduction costs in the climate change regime. Our primary focus is the fair division of efficiency gains that arise from exchanging the initial allocation of emission entitlements, rather than the initial allocation itself. We propose to complement the competitive Walrasian solution with welfare bounds, the ethical justification...

this paper investigates the mechanism of water transportation through aquaporin-4(aqp4) of ratbrain cells by means of molecular dynamics simulation with charmm software. the aqp4 wasembedded into a bilayer made of dimystroilphosphatylcholine (dmpc). the results illustrate thatwater molecules move through aqp4's channel with change of orientation of oxygen of eachwater molecule.

In this project, we explore a data-­‐driven approach for monitoring rail infrastructure from the dynamic response of a train in revenue-­‐service. Presently, rail inspection is performed either visually or with dedicated track geometry cars. We examine a more economical approach where ...

We propose a hybrid architecture MTreeTV to support fast channel switching. MTreeTV combines the use of P2P networks with dedicated streaming servers, and was proposed to build on the advantages of both P2P and CDN paradigms. We study the placement of the servers with constraints on the client to server paths and evaluate the effect of the server parameters. Through analysis and simulation, we ...
