Locally periodic unfolding method and two-scale convergence on surfaces of locally periodic microstructures [PDF]
, 2015 In this paper we generalize the periodic unfolding method and the notion of two-scale convergence on surfaces of periodic microstructures to locally-periodic situations.

New construction method of periodic quasi-complementary sequence set
Tongxin xuebao, 2023 To solve the problem that the number of sequences in the complete complementary sequence set is limited, periodic quasi-complementary sequence set was constructed.Firstly, based on the circular Florentine array, the near optimal periodic quasi ...

Efficient mining of intra-periodic frequent sequences
Array, 2022 Frequent Sequence Mining (FSM) is a fundamental task in data mining. Although FSM algorithms extract frequent patterns, they cannot discover patterns that periodically appear in the data.

Optimal Constructions of Low-Hit-Zone Frequency-Hopping Sequence Sets via Cyclotomy
IEEE Access, 2023 In complex environments of wireless communication, to improve the communication anti-interference performance, quasi-synchronous frequency-hopping (FH) communication system requires low-hit-zone (LHZ) FH sequence sets with optimal Hamming correlation (HC)

On Partitions and Periodic Sequences [PDF]
Tatra Mountains Mathematical Publications, 2019 Abstract In the first part we associate a periodic sequence with a partition and study the connection the distribution of elements of uniform limit of the sequences. Then some facts of statistical independence of these limits are proved.

A Periodic Systems Toolbox for MATLAB [PDF]
, 2005 The recently developed Periodic Systems Toolbox for MATLAB is described. The basic approach to develop this toolbox was to exploit the powerful object manipulation features of MATLAB via flexible andfunctionally rich high level m-functions, while ...

Bifurcations of periodic orbits and uniform approximations. [PDF]
, 1997 We derive uniform approximations for contributions to Gutzwiller's periodic-orbit sum for the spectral density which are valid close to bifurcations of periodic orbits in systems with mixed phase space.
