Abstract Anchored wire meshes are applied worldwide as protective structures against rockfall. The mechanical performance of a mesh is evaluated through laboratory tests, but these generally not representative the field conditions. This paper presents simple tool to predict force-displacement response an anchored panel out-of-plane load, extending experimental standard punch test characteristic...

This study describes an experimental investigation of the thermal efficiency stainless steel mesh and wool as a porous medium in lower channel double pass solar air heater. An setup was planned developed. Various types media with high conductivity different porosities have been tested. The effects porosity wire mesh, media, mass flow rate, intensity radiation studied. Experimental results show ...

This paper uses second-order software for evaluating five Stirling engine parameter?s effect on its performance to select an appropriate configuration with optimal dimensions use in a concentrated solar power plant. Appropriate configuration, heater shape, bundle tube heat exchanger size, and regenerator type geometry are studied. Results show that Alpha is the most suitable high-temperature di...

Lenses are used for multiple applications, including communications, surveillance and security, medical instruments. In homogeneous lenses, the contour is to control electromagnetic propagation. Differently, graded-index lenses make use of inhomogeneous materials, which an extra degree freedom. This freedom enables design devices with a high performance. For instance, rotationally symmetric wit...

Lightweight clay aggregate (LECA) is manufactured by heating with no lime content in the kiln; as a result, water evaporates and angular balls pore structures are obtained. LECA possess internal curing properties any other lightweight due to their structure higher absorption capacity. In this work, experimental analytical behaviour using 100% replacement for coarse make concrete (LWC) beams was...

Despite the numerous advantages of using concrete with high strength capacity, the brittle behavior of high strength concrete (HSC) and higher production cost has limited its use in the construction industry. This research aims to develop a cost-effective approach for production of high strength self-compacting concrete with desirable performance in either compressive or tensile loading conditi...

Microbial electrolysis cells (MECs) provide a high-yield method for producing hydrogen from renewable biomass. One challenge for commercialization of the technology is a lowcost and highly efficient cathode. Stainless steel (SS) is very inexpensive, and cathodes made of this material with high specific surface areas can achieve performance similar to carbon cathodes containing a platinum cataly...
