finite affine groups are given by groups of translations and di-lations on finite cyclic groups. for cyclic groups of prime orderwe develop a time-scale (wavelet) analysis and show that for alarge class of non-zero window signals/vectors, the generatedfull cyclic wavelet system constitutes a frame whose canonicaldual is a cyclic wavelet frame.

Interval narrowing techniques are a key issue for handling constraints over real numbers in the logic programming framework. However, the standard xed-point algorithm used for interval narrowing may give rise to cyclic phenomena and hence to problems of slow convergence. Analysis of these cyclic phenomena shows: 1) that a large number of operations carried out during a cycle are unnecessary; 2)...

Connectivity offers the foundation for achieving required quality of service in all WSN applications. By the concept of cyclic-like topologies proposed and their property proved, we find a new searching method based on cyclic paths on nodes and their combination, which cuts down the cost of ensuring bi-connectivity in this problem. On the basis of graph and probability theory, our centralized c...

We present an OFDM frequency synchronization scheme. This paper presents an extended solution for the carrier frequency synchronization problem of OFDM. The scheme uses number of bits, modulation level, cyclic prefix, FFT size similarly to the algorithm proposed by Tilde Fusco [21].The proposed scheme attains considerably higher accuracy than the scheme by [21] requiring convolutional encoding ...

The unequal error correction capabilities of binary cyclic codes of composite length aye investigated. Under certain conditions, direct sums of concatenated codes have unequal error correction capabilities. By a modified Hartmann and Tzeng algorithm, it is shown that a binary cyclic code of composite length is equivalent to the direct sum of concatenated codes. With this, some binary cyclic une...

Direction of arrival estimation has many applications in communications. Though MUSIC and ESPRIT are by far the mostly studied algorithms, there have been growing interests in cyclostationarity based algorithms for their higher selectivity. In addition to carrier frequency and baud rate, OFDM signals show cyclostationarity caused by the cyclic prefix. In this paper we have studied the direction...

The ScaLAPACK library contains a pair of routines for solving banded linear systems which are strictly diagonally dominant by rows. Mathematically, the algorithm is complete block cyclic reduction corresponding to a particular block partitioning of the system. In this paper we extend Heller’s analysis of incomplete cyclic reduction for block tridiagonal systems to the ScaLAPACK case. We obtain ...

This paper addresses a multi-objective mixed-model two-sided assembly line balancing and worker assignment with bottleneck analysis when the task times are dependent on the worker’s skill. This problem is known as NP-hard class, thus, a hybrid cyclic-hierarchical algorithm is presented for solving it. The algorithm is based on Particle Swarm Optimization (PSO) and Theory of Constraints (TOC) an...

Based on time series gene expressions, cyclic genes can be recognized via spectral analysis and statistical periodicity detection tests. These cyclic genes are usually associated with cyclic biological processes, for example, cell cycle and circadian rhythm. The power of a scheme is practically measured by comparing the detected periodically expressed genes with experimentally verified genes pa...

We describe an algorithm that improves on the standard algorithm for computing the minimal distance of cyclic codes.
