Composite Material Recycling Technology—State-of-the-Art and Sustainable Development for the 2020s
Recently, significant events took place that added immensely to the sociotechnical pressure for developing sustainable composite recycling solutions, namely (1) a ban on composite landfilling in Germany in 2009, (2) the first major wave of composite wind

A Note on the Compositeness of Numbers [PDF]
The "compositeness" of the number n = pclpa2 a * * pam iS defined by Q(n) =a1+a2?+ +Ofa,. If the integers be partitioned into two classes Eo and E1 according to whether Q(n) =0, 1 (mod 2), and Eo(x), El(x) be the corresponding counting functions, it follows that Ei(x) = (x/2) +error.

Experimental and Numerical Study on the Strength of Repaired Steel Pipes with Composite Patches under Internal Pressure [PDF]
Considering the old methods of maintenance and repair of oil and gas pipelines such as welding or replacing a part of the damaged pipeline which include high costs and spending a lot of time, the important usage of novel methods with lower costs such as ...

Adaptive Speaker Recognition Based on Hidden Markov Model Parameter Optimization
The Hidden Markov Model (HMM) is a widely used method for speaker recognition. During its training, the composite order of the measurement probability matrix and the number of re-evaluations of the initial model affect the speed and accuracy of a ...

A Supersymmetric Composite Model of Quarks and Leptons [PDF]
We present a class of supersymmetric models with complete generations of composite quarks and leptons using recent non-perturbative results for the low energy dynamics of supersymmetric QCD. In these models, the quarks arise as composite "mesons" and the
