We construct a verifiable delay function (VDF). A VDF is a function whose evaluation requires running a given number of sequential steps, yet the result can be efficiently verified. They have applications in decentralised systems, such as the generation of ...
Experimental results on the fire endurance of full-scale glass fiber-reinforced polymer (GFRP) composite columns are reported in this paper. The pultruded four-cell profiles were first loaded to axial compression (uniform serviceability stress of 5 MPa) an ...
The concept of confined concrete has been widely accepted throughout the structural engineering field, such as the spiral, steel tube, or carbon fiber composite shell confined concrete, etc. In the present study, this concept has not only been used in the ...
This paper summarizes the findings of a long term experimental program corroborated with detailed finite element simulations that investigated the hysteretic behavior of wide-flange columns in steel moment-resisting frames (MRFs) designed in highly seismic ...
A process window providing guidelines to minimize internal stress levels and to prevent void formation during cure of thermoset composite materials is presented. A model taking into account the applied pressure and the level of stress borne by the fiber as ...
Biocompatible composites, whose porosity and fibre fraction call be tailored over a large range and whose mechanical resistance is comparable to that Of natural bone, were processed with poly(lactic acid) (PLA) and continuous glass fibres. The processing s ...
