Investigation and Optimization of Fast Cold Start of 18650 Lithium-Ion Cell by Heating Film-Based Heating Method

open access: yesEnergies, 2023
In this paper, based on the multi-scale multi-domain (MSMD) battery modeling approach, the NTGK model was used to model the 18650 cylindrical lithium-ion single battery on the electrochemical sub-scale. The model was successful, as it was able to fit the

Task-adaptive Neural Process for User Cold-Start Recommendation [PDF]

open access: yesThe Web Conference, 2021
User cold-start recommendation is a long-standing challenge for recommender systems due to the fact that only a few interactions of cold-start users can be exploited.

Effect of the Air Flow on the Combustion Process and Preheating Effect of the Intake Manifold Burner

open access: yesEnergies, 2022
Diesel engines show poor performance and high emissions under cold-start conditions. The intake manifold burner is an effective method to increase the intake air temperature and improve engine performance.

An embedded bandit algorithm based on agent evolution for cold-start problem

open access: yesInternational Journal of Crowd Science, 2021
PurposeMany recommender systems are generally unable to provide accurate recommendations to users with limited interaction history, which is known as the cold-start problem. This issue can be resolved by trivial approaches that select random items or the

Cold start performance analysis of PEMFC with different assisted heating strategies

open access: yesCase Studies in Thermal Engineering
Large-scale use of proton exchange membrane fuel cell (PEMFC) is restricted by the challenge of cold start. A three-dimensional, transient, multiphase flow cold-start model is established to investigate the effects of different assisted heating ...

Real-time prediction models for remaining cold start time in proton exchange membrane fuel cell based on stack temperature

open access: yesCase Studies in Thermal Engineering, 2023
In order to mitigate the irreversible damage caused by cold start and preserve cell performance, this paper proposes a real-time prediction method based on the remaining cold start time of the proton exchange membrane fuel cell (PEMFC).

Deuterium burning in objects forming via the core accretion scenario - Brown dwarfs or planets?

open access: yes, 2012
Aims. Our aim is to study deuterium burning in objects forming according to the core accretion scenario in the hot and cold start assumption and what minimum deuterium burning mass limit is found for these objects.

STAR-GCN: Stacked and Reconstructed Graph Convolutional Networks for Recommender Systems

open access: yes, 2019
We propose a new STAcked and Reconstructed Graph Convolutional Networks (STAR-GCN) architecture to learn node representations for boosting the performance in recommender systems, especially in the cold start scenario.

Budget-Constrained Item Cold-Start Handling in Collaborative Filtering Recommenders via Optimal Design [PDF]

open access: yes, 2016
It is well known that collaborative filtering (CF) based recommender systems provide better modeling of users and items associated with considerable rating history. The lack of historical ratings results in the user and the item cold-start problems.
