Let A be a finite set and B an arbitrary set with at least two elements. The arity gap of a function f : An → B is the minimum decrease in the number of essential variables when essential variables of f are identified. A non-trivial fact is that the arity gap of such B-valued functions on A is at most |A|. Even less trivial to verify is the fact that the arity gap of B-valued functions on A wit...
We report on first results of an ongoing effort to simulate lattice QCD with two degenerate flavours of quarks by means of the twisted mass formulation tuned to maximal twist. By utilising recent improvements of the HMC algorithm, pseudo-scalar masses well below 300MeV are simulated on volumes L3 · T with T = 2L and L > 2fm and at values of the lattice spacing a . 0.1fm. We present first eviden...
An incompressibility approximation is formulated for isentropic motions in a compressible stratified fluid by defining a pseudo-density ρ∗ and enforcing mass conservation with respect to ρ∗ instead of the true density. Using this approach, sound waves will be eliminated from the governing equations provided ρ∗ is an explicit function of the space and time coordinates and of entropy. By construc...
We demonstrate, both theoretically and experimentally, a pseudo-random, two-dimensional optical phased array (OPA) concept based on tandem injection locking of 64-element vertical cavity surface emitting laser (VCSEL) arrays. A low cavity-Q VCSEL design resulted in an injection locking optical power of less than 1 μW per VCSEL, providing large OPA scaling potential. Tandem injection locking of ...
The kinetic of photo oxidative decolorization of C.I. Acid yellow 23 (AY23) was investigated in UV/ process. The semi-logarithmic of the concentrations of AY23 versus irradiation time were linear, suggesting pseudo-first order reaction. A simple kinetic model is proposed which confirms pseudo- first order reaction. The results indicate that the apparent reaction rate constant is a function of l...
Modern fractal compression methods are based on iterative function systems (IFS), which was developed by Barnsley [1] and Jacquin [2]. During compression, the algorithm partitions the image into a set of square blocks (domain blocks). After this a new partition is made into smaller range blocks [2]. The domain blocks are generally double the size of range blocks. For every range block the neare...
