Effects of offshore artificial islands on beach stability of
Artificial island-type reclamation often exerts certain impacts on near-shore sandy shoreline resources and coastal ecological landscapes. The relationship between Beach nourishment — the addition of sand to increase the width or sand volume of the beach — is a widespread coastal management technique to counteract Beach nourishment has complex implications for the future

Vibroflotation method to improve silt interlayers of dredged coral sand
Taking the vibroflotation of the reclaimed coral sand ground in the South China Sea as a case analysis, this study improved the vibroflotation method with regard to the problem of weak siltAdditive manufacturing of sand molds and cores for metal castings, often called 3D sand-printing (3DSP), is an efficient “freeform” fabrication process that enables rapid production of sand metal castings. The ability to create highly complex molds and cores for advanced metal casting geometries via 3DSP provides unparalleled design Re-Thinking Design Methodology for Castings: 3D Sand

Prediction of sand production onset in petroleum reservoirs
Typical sand production problems case studies and strategies for sand control. SPE Annual Technical Conference and Exhibition, Dallas, Texas (1991) Google Scholar Cost estimation for sheet metal parts using multiple regression and artificial neural networks: a case study. Int. J. Prod. Econ., 111 (2) (2008), pp. 484-492.The sand was set at an initial temperature between 18 and 19 [°C]. The flow of the liquid nitrogen was regulated to provide a constant temperature of −183 [°C]. A parametric study has been carried out to illustrate the effect of the freeze pipe diameter, the distance between freeze pipes, and the coolant temperature on the freezing process.Artificial ground freezing: A review of thermal and hydraulic

Casting Process Improvement by the Application of Artificial
On the way to building smart factories as the vision of Industry 4.0, the casting process stands out as a specific manufacturing process due to its diversity and complexity. One of the segments of smart foundry design is the application of artificial intelligence in the improvement of the casting process. This paper presents an overview K.

Comparing the long‐term effects of artificial and natural
Revegetation has been completed via artificial and natural restoration techniques, and the relative performance of each needs to be further explored. Although some studies have focused on the comparison between artificial and natural methods in vegetation restoration from a micro-perspective, there is a lack of evidence at the Mix proportioning. There were two types of concrete mixes created in this experimental work (Table 2).The control concrete mix (M0) containing cement (400 kg/m 3), stone (1200 kg/m 3), sand (600 kg/m 3) and water (200 kg/m 3).The rest mixes were prepared with GWA of 10%, 20%, and 30% as a partial substitution of sand and with the Engineering properties of concrete incorporating waste

The present study concluded that artificial sand is substitute material to natural sand as fine aggregate in the presence of silica fume with poly carboxylate ether-based superplasticizer can be suitably used in making eco-friendly HPC. Keywords. High performance concrete; Artificial sand; Silica fume; Fly ash; Super plasticizer; Rapid Case Studies in Construction Materials. Volume 15, December 2021, e00677. Interlocking concrete block is a pre-cast artificial stone that is used in several kinds of pavement construction. This shows that the sample with 0% replacement of sand with ceramic waste had a higher split tensile strength than the sample with 20 % Water absorption, strength and microscale properties of interlocking
