Cohen-Macaulay types of certain edge subrings of bipartite graphs and (generalized) Fuss-Catalan numbers
Alin Ştefan
We give an example of two non isomorphic coordinate rings of a special kind of convex polyominoes whose Cohen-Macaulay types are generalized Fuss-Catalan numbers. We further provid…
Physical properties of the trans-Neptunian object (38628) Huya from a multi-chord stellar occultation
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +85
Within our international program to obtain accurate physical properties of trans-Neptunian objects (TNOs) we predicted a stellar occultation by the TNO (38628) Huya of the star Gai…
Fuzzy approach on modelling cyber attacks patterns on data transfer in industrial control systems
Emil Pricop, Sanda Florentina Mihalache
Cybersecurity of industrial control system is a very complex and challenging research topic, due to the integration of these systems in national critical infrastructures. The contr…
On the design of an innovative solution for increasing hazardous materials transportation safety
Emil Pricop
Transportation of hazardous materials represent a high risk operation all over the world. Flammable substances such as oil, kerosene, hydrocarbons, ammonium nitrate or toxic produc…
IoT Forensic -- A digital investigation framework for IoT systems
Snehal Sathwara, Nitul Dutta, Emil Pricop
Security issues, threats, and attacks in relation with the IoT have been identified as promising and challenging area of research. Eventually, the need for a forensics methodology…
Real-time stock analysis for blending recipes in industrial plants
Florin Zamfir, Nicolae Paraschiv, Emil Pricop
Many companies use Excel spreadsheets to keep stock records and to calculate process-specific data. These spreadsheets are often hard to understand and track. And if the user does…
Towards a reliable approach on scaling in data acquisition
Nicolae Paraschiv, Emil Pricop, Jaouhar Fattahi +1
Data acquisition is an important process in the functioning of any control system. Usually, the acquired signal is analogic, representing a continuous physical measure, and it shou…
Properties of the Riemann-Lebesgue integrability in the non-additive case
Domenico Candeloro, Anca Croitoru, Alina Gavrilut +2
We study Riemann-Lebesgue integrability of a vector function relative to an arbitrary non-negative set function. We obtain some classical integral properties. Results regarding the…
Authentication by Witness Functions
Jaouhar Fattahi, Mohamed Mejri, Emil Pricop
Witness functions have recently been introduced in cryptographic protocols' literature as a new powerful way to prove protocol correctness with respect to secrecy. In this paper, w…
On the Security of Cryptographic Protocols Using the Little Theorem of Witness Functions
Jaouhar Fattahi, Mohamed Mejri, Emil Pricop
In this paper, we show how practical the little theorem of witness functions is in detecting security flaws in some category of cryptographic protocols. We convey a formal analysis…
Deviation of the waves in an inhomogeneous medium
Ion Simaciu, Zoltan Borsos, Gheorghe Dumitrescu
Using the formula found by Noorbala and Sepehrinia, the wave deviation in an inhomogeneous medium with continuous variation of propagation velocity is deduced. For electromagnetic…
Considerations regarding security issues impact on systems availability
Emil Pricop, Sanda Florentina Mihalache, Nicolae Paraschiv +2
Control systems behavior can be analyzed taking into account a large number of parameters: performances, reliability, availability, security. Each control system presents various s…
Radiation Pattern Synthesis Using Hybrid Fourier- Woodward-Lawson-Neural Networks for Reliable MIMO Antenna Systems
Elies Ghayoula, Ridha Ghayoula, Jaouhar Fattahi +3
In this paper, we implement hybrid Woodward-Lawson-Neural Networks and weighted Fourier method to synthesize antenna arrays. The neural networks (NN) is applied here to simplify th…
Witness-Functions versus Interpretation-Functions for Secrecy in Cryptographic Protocols: What to Choose?
Jaouhar Fattahi, Mohamed Mejri, Marwa Ziadia +2
Proving that a cryptographic protocol is correct for secrecy is a hard task. One of the strongest strategies to reach this goal is to show that it is increasing, which means that t…
Cryptographic Protocol for Multipart Missions Involving Two Independent and Distributed Decision Levels in a Military Context
Jaouhar Fattahi, Mohamed Mejri, Marwa Ziadia +3
In several critical military missions, more than one decision level are involved. These decision levels are often independent and distributed, and sensitive pieces of information m…
An algorithm to estimate the vertices of a tetrahedron from uniform random points inside
Alina-Daniela Vîlcu, Gabriel-Eduard Vîlcu
In this paper, we give an algorithm to infer the positions of the vertices of an unknown tetrahedron, given a sample of points which are uniformly distributed within the tetrahedro…
On some geometric properties of quasi-product production models
Haila Alodan, Bang-Yen Chen, Sharief Deshmukh +1
In this article we obtain classification results on the quasi-product production functions in terms of the geometry of their associated graph hypersurfaces, generalizing in a new s…
