On Earth many nuclei are unstable, and they can reach a more stable configuration through radioactive decays. These nuclei are indicated as radioactive due to their emission of nuclear radiations. Depending on the emitted particles they are classified as alpha, beta, and gamma decays.

Summary: The high cost of maintenance encourages managers to `optimize' their maintenance schemes. A facet of the `optimizing' performance is being able to predict more precisely the time to failure of components and equipment. In many cases, failure results from degradation. Modelling the degradation process is likely to give rise to better prediction

Bio-inspired consolidants derived from crystalline nanocellulose for decayed wood.
Carbohydrate Polymers, 2018Novel bio-inspired materials derived from crystalline nanocellulose (CNC) have been tested as wood consolidants. A suspension of CNC, produced by acid hydrolysis of cellulose and used as such or mixed with lignin and/or siloxane derivatives (PDMS), was ...

Decays of correlations, and in particular the question of an exponential rate for the decay, are studied both in statistical mechanics by studying the Ruelle-Perron Frobenius operator or in symbolic dynamics, by coding hyperbolic dynamical systems via Markov partitions. This paper shows that the correlations decay exponentially fast for a general class

Exotic decay model and alpha decay studies
Physical Review C, 1990In exotic decay studies, the lifetime of alpha emission occurs crucially in the branching ratio calculation. In this work, we extend our previous exotic decay model to calculate the same. But, in this case unlike in the exotic decay, the redistribution of charge for given masses of the fragments has to be taken into account since the charge-to-mass ...

Decay spectrum and decay subspace of normal operators
Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2001Let A be a self-adjoint operator on a Hilbert space. It is well known that A admits a unique decomposition into a direct sum of three self-adjoint operators Ap, Aac and Asc such that there exists an orthonormal basis of eigenvectors for the operator Ap, the operator Aac has purely absolutely continuous spectrum and the operator Asc has purely singular ...
