In the age of globalization, economic growth and the welfare of nations decisively depend on basic innovations. Therefore, education and knowledge is an important advantage of competition in highly developed countries with high standards of salaries, but raw material shortage. In the twenty-first century, innovations will arise from problem-oriented research, crossing over traditional faculties...

In this paper, we propose a novel improvement for the generalized Lloyd Algorithm (GLA). Our algorithm makes use of an M-tree index built on the codebook which makes it possible to reduce the number of distance computations when the nearest code words are searched. Our method does not impose the use of any specific distance function, but works with any metric distance, making it more general th...

Consider a one dimensional quantum mechanical particle described by the Schrödinger equation on a closed curve of length 2π. Assume that the potential is given by the square of the curve’s curvature. We show that in this case the energy of the particle can not be lower than 0.6085. We also prove that it is not lower than 1 (the conjectured optimal lower bound) for a certain class of closed curv...

TED is a program that “invents” conceptual schematics of optimized thermal systems. TED is based on the view that innovative design can be modeled as a search process and uses elements of the search algorithms that originated in the field of Artificial Intelligence. The search is guided by a special form of exergetic analysis. The theory behind the TED is discussed in details elsewhere. This pa...

Recent developments concerning the possibility of open inflation in quantum cosmology [1,2] have revived an old debate about foundational issues of that subject [2–4]. It is therefore timely to raise an issue which has been largely overlooked previously, but which in our opinion has a direct bearing on these foundational issues. Much of the current debate originates from differing probability a...

Previous work has found that people feel significantly more satisfied with explanations of psychological phenomena when those explanations contain neuroscience information — even when this information is entirely irrelevant to the logic of the explanations. This seductive allure effect was first demonstrated by Weisberg, Keil, Goodstein, Rawson, & Gray (2008), and has since been replicated seve...

The asymptotic optimal performance of variable-rate vector quantizers of fixed dimension and large rate was first developed in a rigorous fashion by Paul Zador. Subsequent design algorithms for such compression codes used a Lagrangian formulation in order to generalize Lloyd’s classic quantizer optimization algorithm to variable rate codes. This formulation has been subsequently adopted in a va...

It has recently been suggested, by Firouzjahi, Sarangi, and Tye, that string-motivated modifications of the Hartle-Hawking wave function predict that our Universe came into existence from “nothing” with a de Sitter-like spacetime geometry and a spacetime curvature similar to that of “low-scale” models of Inflation. This means, however, that the Universe was quite large at birth. It would be pre...
