An introduction to periodical discrete sets from a tomographical perspective
نویسندگان
چکیده
In this paper we introduce a new class of binary matrices whose entries show periodical configurations, and we furnish a first approach to their analysis from a tomographical point of view. In particular we propose a polynomial-time algorithm for reconstructing matrices with a special periodical behavior from their horizontal and vertical projections. We succeeded in our aim by using a reduction involving polyominoes which can be characterized by means of 2− SAT formulas.

متن کاملTomographical aspects of L-convex polyominoes
Our main purpose is to characterize the class of L-convex polyominoes introduced in [3] by means of their horizontal and vertical projections. The achieved results allow an answer to one of the most relevant questions in tomography i.e. the uniqueness of discrete sets, with respect to their horizontal and vertical projections. In this paper, by giving a characterization of L-convex polyominoes,...
متن کاملEvaluation the efficiency of health watch checkup in the diagnosis and treatment of diseases from the perspective of Hamedan police force
Introduction: The health watch checkup project (HWCP) has been conducted in the armed forces since many years ago in order to increase and improve the health condition between the employees. It may be of great importance because of assessing the mental and physical health of armed forces employees; however, conducting the said checkup requires considerable money and time. To analyze the efficie...
متن کاملGenerating Discrete Trace Transition System of a Polyhe-dral Invariant Hybrid Automaton
Supervisory control and fault diagnosis of hybrid systems need to have complete information about the discrete states transitions of the underling system. From this point of view, the hybrid system should be abstracted to a Discrete Trace Transition System (DTTS) and represented by a discrete mode transition graph. In this paper an effective method is proposed for generating discrete mode trans...
متن کاملA New Algorithm for the Discrete Shortest Path Problem in a Network Based on Ideal Fuzzy Sets
A shortest path problem is a practical issue in networks for real-world situations. This paper addresses the fuzzy shortest path (FSP) problem to obtain the best fuzzy path among fuzzy paths sets. For this purpose, a new efficient algorithm is introduced based on a new definition of ideal fuzzy sets (IFSs) in order to determine the fuzzy shortest path. Moreover, this algorithm is developed for ...
