The two pavement structures were identical except for the gradation of the subbase material, where one had a 0/90 mm curve with a controlled fines content, and the other had an open-graded 22/90 mm curve. The APT was conducted using constant dual-wheel loading, and three different ground...
This paper presents the results of the first phase of a research project dealing with the constitutive description of the behaviour of well-graded granular materials when used for base or subbase layers in flexible pavement structures (so-called "unbound granular materials", UGMs). Monotonic and ...
When such material was used in the frost blanket at a rate of 100%, temperature effects were not observed and bearing capacity did not decrease, thus confirming its suitability for use in the frost blanket关键词: cold snowy regions recycled asphalt concrete aggregate subbase course material frost...
Better optimization, especially of distribution networks, and improved demand management and pricing policies are crucial as power systems increase is size and complexity. Particular attention must be paid to identifying and developing hydroelectric resources, based on post-oil crisis relative fuel price ...
对于拥有大量光照的场景,经典的前向渲染(Forward Shading)由于其逐片元的计算通常会产生大量的开销,因此出现了许多用于解决这一问题的算法,常见的有延迟渲染(Deferred Shading)和Forward+渲染,在这一节中我们主要来研究使用Vulkan的Subpass技术来简化延迟渲染的实现(这也是Subpass的主要用途之一)。
Full size image It is known that as the diameter of SiNWs approaches the carrier de Broglie wavelength, the bandgap of SiNW is renormalized due to quantum confinement effects11,57. It is also expected that sub-critical diameter SiNWs exhibit a direct bandgap58, which increases as the nanowir...
Full size image In this work, we reveal an essential difference between chiral symmetry Π and sublattice symmetryS. In the BdG Hamiltonian, Π as the combination ofTandCis an internal symmetry, sinceTandCare both internal symmetries. However, genericallyAandBsublattices are spatially separate on ...

With the universal close-space annealing strategy, the grain size and crystallinity of the WB and NB-MHPs were enhanced, prolonging the carrier lifetimes. The semi-transparent WB subcell has a PCE of 17.02%. The NB subcell has a PCE of 8.13% with the top subcell as the optical filter....
