فرض کنیم g یک گروه آبلی دلخواه و t زیرگروه تابدار ازg باشد. اگر a نسبت به خاصیت مجزا بودن از t ماکسیمال باشد آنگاه a یک زیرگروه t-بلند از g خوانده می شود. در این پایان نامه ابتدا نشان می دهیم که زیرگروه t-بلند l از گروه آبلی g از رتبه بی تاب یک وجود دارد بطوریکه برای هر زیرگروه t-بلند a از g داشته باشیم (type (l) ≤ type (a. در مرحله ی بعد گروههای آبلی از رتبه بی تاب یک که همه ی زیرگروههای t-بل...

Sequences of Nilsson type appear in abundance in Algebraic Geometry, Enumerative Combinatorics, Mathematical Physics and Quantum Topology. We give an elementary introduction on this subject, including the definition of sequences of Nilsson type and the uniqueness, existence, and effective computation of their asymptotic expansion.

We propose in this paper a novel approach to the classification of discrete sequences. This approach builds a model fitting some dynamical features deduced from the learning sample. These features are discrete phase-type (PH) distributions. They model the first passage times (FPT) between occurrences of pairs of substrings. The PHit algorithm, an adapted version of the Expectation-Maximization ...

UNLABELLED The 32-bit Windows application START is implemented using Visual Basic and C(++) and performs analyses to aid in the investigation of bacterial population structure using multilocus sequence data. These analyses include data summary, lineage assignment, and tests for recombination and selection. AVAILABILITY START is available at http://outbreak.ceid.ox.ac.uk/software.htm. CONTAC...

Location fingerprinting is a widely used technique for indoor localization. Traditional fingerprinting methods are generally in point-type, where the received signal strength indicators (RSSI) at discrete points are trained in the offline phase and used as reference in the online phase. This type of radio map requires many human efforts to calibrate and does not take into account the spatial re...
