RISWater Drainage in Double-Porosity Soils: Experiments and Micro–Macro Modeling
Publisher: American Society of Civil Engineers
Abstract: This paper presents the experimental validation of a macroscopic model of unsaturated flow in double-porosity soils, which was developed using the asymptotic homogenization method. The model was implemented into a code ...
Prediction of Sewer Condition Grade Using Support Vector Machines
Publisher: American Society of Civil Engineers
Abstract: Assessing the condition of sewer networks is an important asset management approach. However, because of high inspection costs and limited budget, only a small proportion of sewer systems may be inspected. Tools are therefore ...
Effect of Fly Ash and Reactive MgO on the Engineering Properties and Durability of High-Performance Concrete Produced with Alkali-Activated Slag and Recycled Aggregate
Publisher: ASCE
Abstract: This study investigated the engineering properties and durability of high-performance recycled aggregate concrete (HPRAC) specimens. The specimens were prepared using alkali-activated slag with varying proportions of fly ...
Design of Primary Optical Element with Multiple Sublenses to Improve Irradiance Uniformity over the Receiver of Concentrator Photovoltaic System
Publisher: ASCE
Abstract: In this study, a primary optical element (POE) was designed to collect and distribute solar radiation uniformly on a multijunction solar cell in a concentrator photovoltaic (CPV) system. The POE combined multiple free-form ...
