Some experiments on the successive double-point threshold.

Double Successive Rough Set Approximations

We examine double successive approximations on a set, which we denote by L2L1, U2U1, U2L1, L2U1 where L1, U1 and L2, U2 are based on generally non-equivalent equivalence relations E1 and E2 respectively, on a finite non-empty set V. We consider the case of these operators being given fully defined on its powerset P(V ). Then, we investigate if we can reconstruct the equivalence relations which ...

Relativistic Nonlocality in experiments with successive impacts

Relativistic Nonlocality is applied to experiments in which one of the photons impacts successively at two beam-splitters. Thereby a time series with 2 non-before impacts can be produced with beam-splitters at rest. It is discussed whether such an experiment may allow us to decide between Quantum Mechanics (QM) and Relativistic Nonlocality (RNL).

Some Randomness Experiments on TRIVIUM

This paper develops two methods for exploring the structure of the stream cipher TRIVIUM. We consider whether it is possible to compute the algebraic normal form (ANF) of such functions. Since the key and the IV together make up 160 variables, doing this directly is not possible. Instead, one can choose a subset of the key and IV variables of size n and fix the other variables to constants. As ...

Some Remarks on the Quantum Double

We recall the abstract theory of Hopf algebra bicrossproducts and double cross products due to the author. We use it to develop some less-well known results about the quantum double as a twisting, as an extension and as q-Lorentz group.
