Resilience and robustness are system concepts applicable to structural engineering as well as other areas such as social sciences and economics. This paper explores these two concepts with particular reference to structural systems. Robustness is a structural performance requirement in most structural design codes but there is no method of verification. Resilience is a ̳work in progress‘ concep...
A structural gene which codes for an extracellular protease in Aeromonas hydrophilia SO2/2 and D13 was cloned in Escherichia coli C600-1 by using pBR322 as a vector. The gene codes for a temperature-stable protease with a molecular mass of approximately 38,000 daltons. The protein was secreted to the periplasm of E. coli C600-1 and purified by osmotic shock. Cloned protease (P3) was identical i...
Though still in use today, the method of the effective shearing force to evaluate the maximum shear stress in variable depth beams does not stand close scrutiny. It can lead to overestimating the shearing strength of these beams, although it is suggested as a viable procedure by many otherwise excellent codes of practice worldwide. This paper should help to put the record straight. It should wa...
We study the new problem of Huffman-like codes subject to individual restrictions on the code-word lengths of a subset of the source words. These are prefix codes with minimal expected code-word length for a random source where additionally the code-word lengths of a subset of the source words is prescribed, possibly differently for every such source word. Based on a structural analysis of prop...
In this paper, skew cyclic and skew constacyclic codes over finite non-chain ring R = F_q+uF_q+vF_q, where q= p^m, p is an odd prime and u^{2}=u, v^{2}=v, uv=vu=0 are studied. We show that Gray image of a skew cyclic code of length n over R is a skew quasi-cyclic code of length 3n over F_q of index 3. Structural properties of skew cyclic and skew constacyclic over R are obtained. Further, gener...
Starting from the morphological-functional assumption of the fractal brain, a mathematical model is given by activating brain’s non-differentiable dynamics through the determinism-nondeterminism inference of the responsible mechanisms. The postulation of a scale covariance principle in Schrödinger’s type representation of the brain geodesics implies the spectral functionality of the brain dynam...
The binary and ternary codes spanned by the rows of the point by block incidence matrices of some 2-designs and their complementary and orthogonal designs are studied. A new method is also introduced to study optimal codes.
Dynamic probabilistic risk assessment (DPRA) methodologies couple system simulator codes (e.g., RELAP, MELCOR) with simulation controller codes (e.g., RAVEN, ADAPT). Whereas system simulator codes accurately model system dynamics deterministically, simulation controller codes introduce both deterministic (e.g., system control logic, operating procedures) and stochastic (e.g., component failures...
