On a problem of J. Zaks concerning 5-valent 3-connected planar graphs

Stanislav Jendroľ
1984 Discrete Mathematics  
Zaks formulated the following Eberhard-type problem: Let (Ps, P6 .... ) be a finite sequence of nonnegative integers; does there exist a 5-valent 3-connected planar graph G such that it has exactly Pk  ...  This paper brings a solution to the problem, and similar problems are considered as well.  ...  In the present paper a solution of Zaks' problem is given and also an interesting relationship among certain subsets of ~(5, 3, g) and subsets of ~(2, g), ~d (3, 2, g) and r~(4, 3, g).  ...

An analysis of a class of neural networks for solving linear programming problems

E.K.P. Chong, S. Hui, S.H. Zak
1999 IEEE Transactions on Automatic Control  
A class of neural networks that solve linear programming problems is analyzed.  ...  It is proved that for a given linear programming problem and sufficiently large penalty parameters, any trajectory of the neural network converges in finite time to its solution set.  ...  EXAMPLES We illustrate the use of the proposed neural networks on a linear programming problem adapted from [23, Chapter 1, pp. 39-40], modeling a battery charger circuit with current constraints.  ...

On a problem of Kaplansky II: Every finitely generated Abelian group is the restricted Grothendieck group of a local, Noetherian, Krull domain

Abraham Zaks
1982 Journal of Algebra  
under a joint grant of the Royal Norwegian Council for Scientific and Industrial Research (NTNF) and Israel Council for Research and Development.  ...  ACKNOWLEDGMENT This research was sponsored by the Fund for the Encouragement of Research at the Technion, and was terminated in the summer of 1980 at the University of Bergen where the author was visiting  ...  Following the results in [3] , we are tempted to add to Kaplansky's original problem the condition of the ring being a Krull domain.  ...

Applying CLP to machine translation: A Greek case study
Применение техник ограничительного программирования в машинном переводе на примере новогреческого

Olga N. Nikolaenkova
2019 Journal of Applied Linguistics and Lexicography  
For this purpose, we tested CP techniques on a linguistic problem of polysemy in machine translation. Ambiguity arises almost every time computers try to deal with human language.  ...  The translation is based on the results of two parsers -the English and the Greek one. Parsing uses a set of constraints (both semantic and grammatical).  ...  -getr(A,(o,zak,elenkse,tin,ptosi,tou,ousiastikou),()).A = (zak,checked,the,case,of,the,noun) ; A = (zak,checked,the,case,of,the,noun) ; A = (zak,checked,the,case,of,of,the,noun) ; A = (zak,checked,the,  ...

Zak transform and a new approach to waveform design

I. Gladkova
2001 IEEE Transactions on Aerospace and Electronic Systems  
In the Zak domain, computation of A f (¿ , º) on the integer lattice is exceptionally simple, particularly for pulse train signals.  ...  For a pulse train, the Zak transform is gotten by multiplying the Zak transform of a rectangular pulse of duration 1 by a multivariate trigonometric polynomial whose coefficients are the coefficients defining  ...  An intriguing possibility is to take '(x, y) to be a radial function, i.e., a function of r = p x 2 + y 2 , which leads to a computationally one-dimensional problem.  ...

Edge modes in active systems of subwavelength resonators [article]

Habib Ammari, Erik Orvehed Hiltunen
2020 arXiv   pre-print
We demonstrate that localized edge modes appear in a periodic structure of subwavelength resonators with a defect in the gain/loss distribution, and explicitly compute the corresponding frequency and decay  ...  Similarly to the Hermitian case, these edge modes can be attributed to the winding of the eigenmodes.  ...  In the Hermitian case, the topological properties of one-dimensional insulators can be described by the Zak phase.  ...

The role of a form of vector potential — normalization of the antisymmetric gauge

Wojciech Florek, Stanisław Wałcerz
1998 Journal of Mathematical Physics  
Results obtained for the antisymmetric gauge A=[Hy,-Hx]/2 by Brown and Zak are compared with those based on pure group-theoretical considerations and corresponding to the Landau gauge A=[0,Hx].  ...  A period N introduced in Brown's and Zak's papers should be considered as a magnetic one, whereas the crystal period is in fact 2N.  ...  their papers are still considered as fundamental ones. 5 Brown and Zak proved that the problem considered is in fact two-dimensional and their investigations confirmed the importance of projective representations  ...
