State and Parameter Estimation of the Lorenz System in Existence of Colored Noise
Mozhgan Mombeini, Hamid Khaloozadeh
Many researchers are interested to use Extended Kalman Filter (EKF) for state estimation of complex nonlinear dynamics with uncertainties which modeled with white noises. On the ot…
Robustness of a topological phase: Topological color code in parallel magnetic field
Saeed S. Jahromi, Mehdi Kargarian, S Farhad Masoudi +1
The robustness of the topological color code, which is a class of error correcting quantum codes, is investigated under the influence of an uniform magnetic field on the honeycomb…
A basic class of symmetric orthogonal polynomials of a discrete variable
Mohammad Masjed-Jamei, Iván Area
By using a generalization of Sturm-Liouville problems in discrete spaces, a basic class of symmetric orthogonal polynomials of a discrete variable with four free parameters, which…
Improving the K-means algorithm using improved downhill simplex search
Ehsan Saboori, Shafigh Parsazad, Anoosheh Sadeghi
The k-means algorithm is one of the well-known and most popular clustering algorithms. K-means seeks an optimal partition of the data by minimizing the sum of squared error with an…
Automatic firewall rules generator for anomaly detection systems with Apriori algorithm
Ehsan Saboori, Shafigh Parsazad, Yasaman Sanatkhani
Network intrusion detection systems have become a crucial issue for computer systems security infrastructures. Different methods and algorithms are developed and proposed in recent…
A new scheduling algorithm for server farms load balancing
Ehsan Saboori, Shahriar Mohammadi, Shafigh Parsazad
This paper describes a new scheduling algorithm to distribute jobs in server farm systems. The proposed algorithm overcomes the starvation caused by SRPT (Shortest Remaining Proces…
Cosmological solutions of Tensor-Vector theories of gravity with varying the space-time-matter coupling constant
Azam Izadi, Ali Shojai, Mojtaba Nouradini
We consider tensor-vector theories with varying the space-time-matter coupling constant (varying Einstein velocity) in a spatially flat FRW universe. We examine the dynamics of thi…
Integral trees with given nullity
E. Ghorbani, A. Mohammadian, B. Tayfeh-Rezaie
A graph is called integral if all eigenvalues of its adjacency matrix consist entirely of integers. We prove that for a given nullity more than 1, there are only finitely many inte…
OGY Control of Haken Like Systems on Different Poincare Sections
Mozhgan Mombeini
The Chua system, the Lorenz system, the Chen system and The Lü system are chaotic systems that their state space equations is very similar to Haken system which is a nonlinear mode…
Dependence of interface conductivity on relevant physical parameters in polarized Fermi mixtures
N. Ebrahimian, M. Mehrafarin, R. Afzali
We consider a mass-asymmetric polarized Fermi system in the presence of Hartree-Fock (HF) potentials. We concentrate on the BCS regime with various interaction strengths and numeri…
Parity Check Matrix Recognition from Noisy Codewords
Yasser Karimian, Saeideh Ziapour, Mahmoud Ahmadian Attari
We study recovering parity check relations for an unknown code from intercepted bitstream received from Binary Symmetric Channel in this paper. An iterative column elimination algo…
Thin film growth by using random shape cluster deposition
ZH. Ebrahiminejad, Seyed Farhad Masoudi, R. S. Dariani +1
The growth of a rough and porous thin surface by deposition of randomly shaped clusters with different sizes over an initially flat linear substrate is simulated, using Monte Carlo…
One directional Polarized Neutron Reflectometry with optimized reference layer method
Seyed Farhad Masoudi, Saeed S. Jahromi
In the past decade, several neutron reflectometry methods for determining the modulus and phase of the complex reflection coefficient of an unknown multilayer thin film have been w…
Investigating the effects of smoothness of interfaces on stability of probing nano-scale thin films by neutron reflectometry
S. S. Jahromi, S. F. Masoudi
Most of the reflectometry methods which are used for determining the phase of complex reflection coefficient such as reference method and Variation of Surroundings medium are based…
Optimal Rate and Maximum Erasure Probability LDPC Codes in Binary Erasure Channel
H. Tavakoli, M. Ahmadian Attari, M. R. Peyghami
In this paper, we present a novel way for solving the main problem of designing the capacity approaching irregular low-density parity-check (LDPC) code ensemble over binary erasure…
Decoherence Effects on Superpositions of Chiral States in a Chiral Molecule
Mohammad Bahrami, Afshin Shafiee, Angelo Bassi
The superposition of chiral states of chiral molecules, as delocalized quantum states of a many-particle system, can be used for the experimental investigations of decoherence theo…
Spanning trees and even integer eigenvalues of graphs
Ebrahim Ghorbani
For a graph , let and be the Laplacian and signless Laplacian matrices of , respectively, and be the number of spanning trees of . We prove that if $G…
On Order and Rank of Graphs
E. Ghorbani, A. Mohammadian, B. Tayfeh-Rezaie
The rank of a graph is defined to be the rank of its adjacency matrix. A graph is called reduced if it has no isolated vertices and no two vertices with the same set of neighbors.…
