Fibres for enhancing of the bond capacity between GFRP rebar and concrete [PDF]
, 2014 The effect of steel fibres (SF) and macro-polypropylene fibres (PPA) on the bond capacity between GFRP rebar and concrete has been studied in this work. A novel method using the equivalent bond strength to evaluate the bond toughness is proposed.

Input Synthesis for Sampled Data Systems by Program Logic
, 2015 Inspired by a concrete industry problem we consider the input synthesis problem for hybrid systems: given a hybrid system that is subject to input from outside (also called disturbance or noise), find an input sequence that steers the system to the ...
