Qualified residue difference sets with zero
1998
Discrete Mathematics
In this paper we point out that if zero is counted as a residue then we can obtain further qualified residue difference sets for both the biquadratic and the sextic residues. ...
We previously established that biquadratic qualified residue difference sets exist for primes p if and only if p = 16x 2 + 1 and sextic qualified residue difference sets exist if and only if p = 108x 2 ...
Theorem 3 . 3 If prime p=kn + 1 (k even) then a necessary and sufficient condition for the set R*= {O, rl,r2 ..... rk} (nth power residues and zero) to form a qualified residue difference set, with qualifier ...

An extension for residue difference sets
1997
Discrete Mathematics
In this paper we extend the idea of residue difference sets, with existence theorems being established for certain classes of primes. ...
We call R a qualified residue difference set if there exists some non-zero integer m ¢ R which is such that if we form all the non-zero differences ri-mrj(modp): l<~i,j~k, we obtain every positive integer ...
We will refer to this new type of residue difference set as a qualified residue difference set. ...

QUALIFIED DIFFERENCE SETS FROM UNIONS OF CYCLOTOMIC CLASSES
2009
Bulletin of the Australian Mathematical Society
Qualified difference sets (QDS) composed of unions of cyclotomic classes are discussed. ...
An exhaustive computer search for such QDS and modified QDS that also possess the zero residue has been conducted for all powers n = 4, 6, 8 and 10. ...
Acknowledgements The authors would like to thank Dr Shaun Cooper and Professor Ron Evans for their help with this article. ...

We call m a qualifier of multiplicity λ for the set R. If zero is counted as a residue we can obtain further qualified residue difference sets. ...
We call R a qualified residue difference set (QRDS) if there exists some non-zero integer m / ∈ R which is such that if we form all the non-zero differences r i − mr j (mod p), 1 ≤ i, j ≤ k, we obtain ...

Lam's power residue addition sets
2011
Advances in Applied Mathematics
Classical n-th power residue difference sets modulo p are known to exist for n = 2, 4, 8. ...
In 1976, Lam showed that qualified n-th power residue difference sets modulo p exist for n = 2, 4, 6, and he proved their nonexistence for all odd n and for n = 8, 10, 12. ...
If m / ∈ H n , we call such an addition set a qualified power residue difference set modulo p with qualifier m; cf. [14, 15] . ...

Polynomial construction of complex Hadamard matrices with cyclic core
1999
Applied Mathematics Letters
In conjunction with a certain uniformity property of polynomial coeffÉcients, these conditions yield a simple method by which complex Hadamard matrices with cyclic core can be constructed. ...
In such cases, a real p-ary linear cyclic error correcting code may be associated with the complex Hadamard matrix. ...
Ifj is a residue in Gf(p), let Aj be the multiplicity of j, as a member of the set of elements of V. If j is not such an element, define the multiplicity to be zero. ...

Residue Classes of the PPT Sequence
[article]
2013
arXiv
pre-print
Primitive Pythagorean triples (PPT) may be put into different equivalence classes using residues with respect to primes. ...
We show that the probability that the smaller odd number associated with the PPT triple is divisible by prime p is 2/(p+1). ...
Residue Classes We first prove a result on the number a (of the triple a, b, c) of PPTs for it to have zero residue with respect to mod p. ...

Dipole Anisotropy as an Essential Qualifier for the Monopole Component of the Cosmic-Dawn Spectral Signature, and the Potential of Diurnal Pattern for Foreground Estimation
[article]
2018
arXiv
pre-print
Such dipole qualifier for the monopole spectrum, when combined with reliable foreground estimation, is expected to pave way for in situ validation of spectral signatures from early epochs, important to ...
We describe details of such a test, and illustrate its application with the help of simulations. ...

Fault Detection and Isolation of a Three-tank System Using Analytical Temporal Redundancy – Parity Space/Relation Based Residual Generation
2020
International Journal of Advances in Scientific Research and Engineering
It is based on residual generation using a parity equations/space approach. The paper further briefly outlines other approaches of model-based residual generation. ...
These residuals were then used to detect whether or not the system is faulty and indicate the location of the fault when it is faulty. ...
Such residual-sets are said to be structured, which thus implies that each residual is completely unaffected by a different subset of faults. ...
