When the logarithmic function is approximated by sequences of algebraic functions, similar questions can be posed as in the case of other similar problems. So, for example, it is interesting to ...

How can we tell whether a (infinite) binary sequence is "random"? Given the difficulty of the question and the non-universal nature of the answers (random in what sense? for what use?), we can imagine ...

Abstract: Frequency-hopping (FH) spread spectrum and direct-sequence spread spectrum are two main spread-coding technologies. Frequency-hopping sequences are needed in FH code-division multiple-access ...

Proceedings of the American Mathematical Society, Vol. 102, No. 3 (Mar., 1988), pp. 473-479 (7 pages) We present criteria for irrationality of limits of convergent sequences of rational numbers, ...

Automatic sequences or their generalizations (multi-dimensional automatic sequences, morphic sequences, q-regular sequences, etc.) have many properties, which mean they can be found in many branches ...

Abstract: In this paper, we first present a modified code-spread code-division multiple-access (CS-CDMA) scheme, named phase-scrambling CDMA (PS-CDMA), for a Gaussian multiple access channel (MAC). In ...

Number sequences are sets of numbers that follow a pattern or a rule. Each number in a sequence is called a term. A sequence which increases or decreases by the same amount each time is called a ...

Department of Mathematics, Faculty of Education, Gifu University, Gifu, Japan. and that (see e.g. [4-8]). Below in this paper we write. We let G.C.D. denote “greatest common divisor” as usual. One has ...

Important note: the package is being updated: a new subpackge, DalgSeq, is under construction. It will contains all commands for difference-algebraic sequences, including thre recent ...

The algebraic expressions produced by the translation in Section 18.2 Translation to the SPARQL Algebra may contain, as a sub-expression, a multiset of solution mappings or a sequence of solution ...
