Set of Frequency-Hopping Sequence with Optimal Hamming Correlation

Applied Mechanics and Materials, 2014
In wireless communication systems, frequency hopping (FH) spread spectrum and direct sequence spread spectrum are two main spread coding technologies. In this paper,by the Cartesian product, we construct one class of one-coincidence frequency-hopping sequence set.

Correlation between clinical symptoms and peripheral immune response in HAM/TSP

Microbial Pathogenesis, 2016
HTLV-1 infects principally CD4+ T cells that are the main reservoirs of the virus in vivo, which play an important role in the immunological response. Most of the infected patients are asymptomatic. However, 2-3% of patients will develop HAM/TSP or Adult T lymphoma.

Phenotypic correlations among quality traits of fresh and dry-cured hams

Meat Science, 2007
In this study, fresh and processing quality traits were collected on a total of 312 Country Hams. Phenotypic correlations between traits were estimated and numerous values were significantly different ...

On the Aperiodic Hamming Correlation of Frequency-Hopping Sequences from Norm Functions

2012
Frequency-hopping sequences (FHSs) are needed in frequency hopping code-division multiple-access (FH-CDMA) systems. Aperiodic Hamming correlation of FHSs matters in real applications, while it received little attraction in the literature compared with periodic Hamming correlation. In this paper, we study the aperiodic Hamming correlation of a family of

Lower Bounds on the Hamming Auto- and Cross Correlations of Frequency-Hopping Sequences

IEEE Transactions on Information Theory, 2004
Frequency hopping (FH) sequences have found wide applications in various modern FH spread-spectrum communications and radar systems. In FH spread-spectrum communications, the interference occurs when two distinct transmitters use the same frequency simultaneously. In order to evaluate the goodness of FH sequence design, the Hamming correlation function

New hamming score based correlation method for fingerprint identification

2015 6th International Conference on Computers and Devices for Communication (CODEC), 2015
Now-a-day fingerprint matching is considered as a subset of biometrics. It plays an important role in offices and industries to register the attendance of the employees, and in forensic departments for criminal identification. Although minutia based detection has gained more popularity, but it shows poor performance in case of low quality images ...

Correlation and Self-Repulsion in Studies of Molecular Ions with the Ham Method

1983
In the study of positive and negative molecular ions the primary data can be said to be the energies which are required to produce them from the molecules. The ionization energies are usually calculated using Koopmans’ theorem, which means, that the accuracy depends upon the extent to which the correlation energy change and the reorganization energy ...

New Families of Frequency-Hopping Sequence Sets with Optimal Hamming Correlation

International Journal of Foundations of Computer Science
With the advantage of transmitting messages efficiently along with switching frequencies at set intervals by each user, frequency-hopping sequence (FHS) has been widely applied in the frequency-hopping multiple access spread spectrum systems. In such systems, the Hamming correlation property of FHS is an important standard to measure the system ...

Histophysiology of the pituitary gland in correlation with the ovarian cycle in Tor (Barbus) tor (Ham.)

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1966
The histophysiology of the pituitary gland has been studied in correlation with the phases of the ovarian cycle in Tor (Barbus) tor. The cyanophilic cells in the proximal pars distalis display changes related to stages in the maturation of the ovary.
