Abstract

In recent years, domestic and international policies to support energy-efficient buildings have been intensively introduced, and a consensus has been reached in the direction of green buildings. Building photovoltaic integration is a key technology to solve the demand for electricity in energy-efficient buildings. Meanwhile, prefabricated assembly house construction, as a common construction technology in the current building field, has the advantages of a short construction period, low project cost, a wide range of applications, and high structural stability. Green building and building industrialization are the direction of future construction industry development, combining building photovoltaic (PV) integration with assembly building, breaking down the whole structure into simple components in the factory standardization, batch production, and then on-site assembly, can reduce the mold cost, speed up the construction speed, and improve economic efficiency. The PV solar integrated assembled facade is in line with the concept of energy saving, low carbon, and environmental protection, with significant social benefits, which helps to promote rapidly in the market. In this article, by analyzing the performance and characteristics of PV modules, we propose the design method of PV-integrated prefabricated components for assembled buildings based on sensing technology, extract relevant design parameters from the database of building PV-integrated components, and test the feasibility of the modeling scheme in four stages of engineering design. The use of the results shows that the method of this article can target to improve the accuracy of PV-integrated prefabricated components, ensure the efficiency of component production and processing, and play an important role in supporting the widespread application of modern construction technology for building PV-integrated prefabricated assemblies.

Abstract

Intracranial atherosclerotic disease (ICAD) is a common cause of ischaemic stroke and transient ischaemic attack (TIA) with a high recurrence rate. It is often referred to as intracranial atherosclerotic stenosis (ICAS), when the plaque has caused significant narrowing of the vessel lumen. The lesion is usually considered symptomatic ICAD/ICAS (sICAD/sICAS) when it has caused an ischaemic stroke or TIA. The severity of luminal stenosis has long been established as a prognostic factor for stroke relapse in sICAS. Yet, accumulating studies have also reported the important roles of plaque vulnerability, cerebral haemodynamics, collateral circulation, cerebral autoregulation and other factors in altering the stroke risks across patients with sICAS. In this review article, we focus on cerebral haemodynamics in sICAS. We reviewed imaging modalities/methods in assessing cerebral haemodynamics, the haemodynamic metrics provided by these methods and application of these methods in research and clinical practice. More importantly, we reviewed the significance of these haemodynamic features in governing the risk of stroke recurrence in sICAS. We also discussed other clinical implications of these haemodynamic features in sICAS, such as the associations with collateral recruitment and evolution of the lesion under medical treatment, and indications for more individualised blood pressure management for secondary stroke prevention. We then put forward some knowledge gaps and future directions on these topics.

17. Physics-Informed Koopman Network

Abstract

Koopman operator theory is receiving increased attention due to its promise to linearize nonlinear dynamics. Neural networks that are developed to represent Koopman operators have shown great success thanks to their ability to approximate arbitrarily complex functions. However, despite their great potential, they typically require large training data-sets either from measurements of a real system or from high-fidelity simulations. In this work, we propose a novel architecture inspired by physics-informed neural networks, which leverage automatic differentiation to impose the underlying physical laws via soft penalty constraints during model training. We demonstrate that it not only reduces the need of large training data-sets, but also maintains high effectiveness in approximating Koopman eigenfunctions., Comment: 26 pages, 5 figures
