It is common to identify the class of computable functions with the class of functions computable by the Turing machine. The identification is done on the ground of the famous Church-Turing thesis. In fact, the thesis justifies only one implication: computable function are Turing computable. The other implication is quite obviously false if computability means practical computability. I am not ...
Huygens' principle (HP) is understood as a universal principle governing not only the propagation of light, but also of acoustic waves, heat and matter di!usion, SchroK dinger's matter waves, random walks, and many more. According to Hadamard's rigorous de"nition, HP comprehends the principle of action-by-proximity (cf. Faraday's "eld theory, etc.) and the superposition of secondary wavelets (H...
This paper introduces a Minimum Description Length (MDL) principle to de ne tness functions in Genetic Programming (GP). In traditional (Koza-style) GP, the size of trees was usually controlled by user-de ned parameters, such as the maximum number of nodes and maximum tree depth. Large tree sizes meant that the time necessary to measure their tnesses often dominated total processing time. To ov...
The aim of this chapter is to investigate the line from the 19th century, through Frege’s works, to the appearance of the principle of compositionality in modern sciences. It is shown that contextuality and compositionality were discussed at the beginnings of the 19th century, but that contextuality was favoured. Also for Frege contextuality was the basic principle and he always obeyed it. Alth...
Abtrac t This paper presents an FIR fllter system capable of implementing virtually any practical lowpass and highpass filter with as little as 60-60 multiplications per sample. The method b based on multirate techniques and complementary Alters. We first give a brief presentation of the principle and the necessary building blocks. Then, practical design methods for optimitation are presented t...
Objective: Today the Countries identify values, principles, rules, norms of human rights and the solution of guarantee a, execution and supervision on these by collection of documents. Doctrines, Practices and Institutions that have had it under the title of the international human rights. According to this system. in light of the total international regulations related to human rights, has...
An adequate theory of partial computable functions should provide a basis for deening computational complexity measures and should justify the principle of computational induction for reasoning about programs on the basis of their recursive calls. There is no practical account of these notions in type theory, and consequently such concepts are not available in applications of type theory where ...
In this paper, we investigate the fuzzy logic based system characteristics of MX/G/1 retrial queuing system with Bernoulli vacation schedule. The service time and vacation time are assumed to be generally distributed. It is found in many practical situations that the queuing models with fuzzy parameters are much more realistic than the classical crisp parameters based queuing models. We have...
This paper proposes a new single phase transformerless Photovoltaic (PV) inverter for grid connected systems. It consists of six power switches, two diodes, one capacitor and filter at the output stage. The neutral of the grid is directly connected to the negative terminal of the source. This results in constant common mode voltage and zero leakage current. Model Predictive Controller (MPC) tec...
