Hydrogen is believed as a promising energy carrier that contributes to deep decarbonization, especially for the sectors hard be directly electrified. A grid-connected wind/hydrogen system typical configuration hydrogen production. For such system, critical barrier lies in poor cost-competitiveness of produced hydrogen. Researchers have found flexible operation possible thanks excellent dynamic ...

Numerical simulation is extensively used in heat exchanger design and performance evaluation. While evaluating potential working fluids, pure fluids and fluid mixtures with different component combinations and fractions are compared based on simulation results. Two of the challenges while conducting such studies are the uncertainties of refrigerant properties and the applicability of empirical ...

Model-based data-interpretation techniques are widely used to identify the behavior of structures. These techniques exploit information provided by in-situ measurements to make diagnosis related to structural performance. In the context of model-based infrastructure diagnoses, measuring and modeling uncertainties are generally estimated using engineering heuristics. The accuracy of diagnosis is...

PURPOSE: There are a number of potential strategies and approaches for managing aquatic nuisance species (ANS). This technical note will consider how decision-makers and stakeholders can resolve conflicting goals and scientific uncertainties that otherwise impair evaluation and selection of a method to address a specific problem. Value trade-offs exist among multiple objectives and scientific u...

We propose a general approach to describe large amplitude motions (LAM) with multiple degrees of freedom (DOF) in molecules or reaction intermediates, which is useful for the computation of thermochemical or kinetic data. The kinetic part of the LAM Lagrangian is derived using a Z-matrix internal coordinate representation within a new numerical procedure. This derivation is exact for a classica...

In medical image analysis (MIA) and computer-assisted surgery (CAS), aligning two multiple point sets (PSs) together is an essential but also a challenging problem. For example, rigidly into one common coordinate frame prerequisite for statistical shape modelling (SSM). Accurately the pre-operative space with intra-operative in CAS very crucial to successful interventions. this article, we form...
