Thermal Analysis of Cells Behavior in Modular Lithium Iron Phosphate Battery System in Urban Electric Bus Fleet

open access: yesEnergy Science &Engineering, EarlyView.
Real‐world analysis of lithium iron phosphate battery systems in electric buses shows minimal short‐term temperature impact on energy but significant long‐term degradation at higher temperatures. Efficient cooling and thermal uniformity are critical to prevent accelerated aging, maintain performance, and ensure safety under dynamic operating conditions.

Emergent Constraints on Regional Cloud Feedbacks [PDF]

open access: yesGeophysical Research Letters, 2021
Low-cloud based emergent constraints have the potential to substantially reduce uncertainty in Earth’s Equilibrium Climate Sensitivity, but recent work has shown that previously-developed constraints fail in the latest generation of climate models, suggesting that new approaches are needed. Here, we investigate the potential for emergent constraints to

Provenance of Feedback in Cloud Services

2014 IEEE 8th International Symposium on Service Oriented System Engineering, 2014
With the fast adoption of Services Computing, even more driven by the emergence of the Cloud, the need to ensure accountability for quality of service (QoS) for servicebased systems/services has reached a critical level. This need has triggered numerous researches in the fields of trust, reputation and provenance.

Feedback-based optimization of a private cloud

Future Generation Computer Systems, 2012
The optimization problem addressed by this paper involves the allocation of resources in a private cloud such that cost to the provider is minimized (through the maximization of resource sharing) while attempting to meet all client application requirements (as specified in the SLAs). At the heart of any optimization based resource allocation algorithm,

DROPLET FEEDBACK ON VAPOR IN A WARM CLOUD

International Journal of Modern Physics B, 2009
A new model to study the effect of turbulence on the cloud droplets in the condensation phase is proposed and its behavior investigated by direct numerical simulations. The model is a generalization of the one by Celani, Mazzino, Tizzi, New J. Phys.10, 075021 (2008), where the droplet feedback on vapor is now explicitly taken into account. Physically,

Low-Cloud Feedbacks from Cloud-Controlling Factors: A Review [PDF]

open access: yesSurveys in Geophysics, 2017
AbstractThe response to warming of tropical low-level clouds including both marine stratocumulus and trade cumulus is a major source of uncertainty in projections of future climate. Climate model simulations of the response vary widely, reflecting the difficulty the models have in simulating these clouds.

On the Use of Cloud Forcing to Estimate Cloud Feedback

Journal of Climate, 2004
Abstract Uncertainty in cloud feedback is the leading cause of discrepancy in model predictions of climate change. The use of observed or model-simulated radiative fluxes to diagnose the effect of clouds on climate sensitivity requires an accurate understanding of the distinction between a change in cloud radiative forcing and a cloud feedback.

Cloud radios with limited feedback

2014 International Conference on Signal Processing and Communications (SPCOM), 2014
Cooperation in a cellular network is seen as a key technique in managing other cell interference to observe a gain in achievable rate. In this paper, we present the achievable rates for a cloud radio network using a zero forcing (ZF) equalizer with dirty paper precoding (DPC).

Clouds, Cloud Observations and Cloud Feedbacks

1994
The H2O molecule is one of the fundamental building blocks of the Earth’s climate system. A remarkable feature of our planet is the existence of significant amounts of water in solid, liquid and gaseous form. Water is continually recycled between these three phases of the hydrological cycle, all of which play important roles in the climate system.
