We consider the existence of robust strange nonchaotic attractors in a simple class of quasiperiodically forced systems. Rigorous results are presented demonstrating that the resulting attractors are strange in the sense that their box-counting dimension D0 is larger than their information dimension D1 by 1 (i.e., D(0)=D(1)+1). We also show how this property is manifested in numerical experiments.

In 1966, Golomb showed that any polyomino which tiles a rectangle also tiles a larger copy of itself. Although there is no compelling reason to expect the converse to be true, no counterexamples are known. In 3 dimensions, the analogous result is that any polycube that tiles a box also tiles a larger copy of itself. In this note, we exhibit a polycube (a ‘notched cube’) that tiles a larger copy...

We study massless one-loop box integrals by treating the number of space-time dimensions D as a negative integer. We consider integrals with up to three kinematic scales (s, t and either zero or one off-shell legs) and with arbitrary powers of propagators. For box integrals with q kinematic scales (where q = 2 or 3) we immediately obtain a representation of the graph in terms of a finite sum of...

The elimination of Reactive Red 120 (RR120) from synthetic solution using biochar generated Ulva prolifera was investigated. process parameters sorbent dose (A), pH (B), initial dye concentration (C), and temperatures (D) were optimized response surface methodology (RSM). To estimate the removal effectiveness with best 27 trails, Box-Behnken method (blocked) utilised. Analysis variance (ANOVA),...
A cutting-plane procedure for integer programming (IP) problems usually involves invoking a blackbox procedure (such as the Gomory-Chvátal (GC) procedure) to compute a cutting-plane. In this paper, we describe an alternative paradigm of using the same cutting-plane black-box. This involves two steps. In the first step, we design an inequality cx ≤ d where c and d are integral, independent of th...
