Three-Receiver Broadcast Channel with Side Information
Saeed Hajizadeh, Ghosheh Abed Hodtani
Three-Receiver broadcast channels (BC) are of interest due to their information-theoretic differences with two-receiver one. In this paper, we derive achievable rate regions for tw…
Stability of vacua in New Massive Gravity in different gauges
Ahmad Ghodsi, Davood Mahdavian Yekta
We consider AdS3 and warped AdS3 vacua in new massive gravity and study the highest weight modes and general propagating modes as a set of solutions for the linearized equations of…
Double field domain walls with explicit symmetry breaking
Nematollah Riazi, Marzieh Peyravi, Shahram Abbassi
We study the dynamics of domain walls in a double-field model in which the U(1) symmetry is broken both spontaneously and explicitly. The global U(1) symmetry of the system is rest…
Rate-Distortion Analysis of Multiview Coding in a DIBR Framework
Boshra Rajaei, Thomas Maugey, Hamid-Reza Pourreza +1
Depth image based rendering techniques for multiview applications have been recently introduced for efficient view generation at arbitrary camera positions. Encoding rate control h…
Some Theoretical Results Concerning non-Parametric Estimation by Using a Judgment Post-stratification Sample
Ali Dastbaravarde, Nasser Reza Arghami, Majid Sarmad
In this paper, some of the properties of non-parametric estimation of the expectation of g(X) (any function of X), by using a Judgment Post-stratification Sample (JPS), are discuss…
Relationship between the Hyers-Ulam stability and the Moore-Penrose inverse
Qianglian Huang, Mohammad Sal Moslehian
In this paper, we establish a link between the Hyers-Ulam stability and the Moore--Penrose inverse, that is, a closed operator has the Hyers-Ulam stability if and only if it has a…
Ricci curvature corrections to type II supergravity
Mohammad R. Garousi
We examine the NS-NS corrections to the type II supergravity given by Gross and Sloan, under the linear T-duality transformations. We show that the gravity and the B-field coupling…
Does HM mechanism work in string theory?
Alireza Sepehri, Somayyeh Shoorvazi, Mohammad Ebrahim Zomorrodian
The correspondence principle offered a unique opportunity to test the Horowitz and Maldacena mechanism at correspondence point "the centre of mass energies around $(M_{s}/(g_{s})^{…
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…
T-duality of the Riemann curvature corrections to supergravity
Mohammad R. Garousi
We examine the known Riemann curvature corrections to the supergravity action at order under the T-duality transformations. Using the compatibility of the action with the li…
Bipolar jets launched from magnetically diffusive accretion disks. I. Ejection efficiency vs field strength and diffusivity
Somayeh Sheikhnezami, Christian Fendt, Oliver Porth +2
We investigate the launching of jets and outflows from magnetically diffusive accretion disks. Using the PLUTO code we solve the time-dependent resistive MHD equations taking into…
Analysis of Coverage Region for MIMO Relay Channel
Alireza Alizadeh, Ghosheh Abed Hodtani
In this paper we investigate the optimal relay location in the sense of maximizing suitably defined coverage region for MIMO relay channel. We consider the general Rayleigh fading…
Structure of ADAFs in a general large-Scale B-field: The role of wind and thermal conduction
A. Mosallanezhad, M. Khajavi, S. Abbassi
We have explored the structure of hot flow bathed in a general large-scale magnetic field. The importance of outflow and thermal conduction on the self-similar structure of a hot a…
Large-sample study of the kernel density estimators under multiplicative censoring
Masoud Asgharian, Marco Carone, Vahid Fakoor
The multiplicative censoring model introduced in Vardi [Biometrika 76 (1989) 751--761] is an incomplete data problem whereby two independent samples from the lifetime distribution…
Interpretation of the large-deformation high spin bands in selected A=158-168 nuclei
A. Kardan, I. Ragnarsson, H. Miri-Hakimabad +1
The high-spin rotational bands in 168Hf and the triaxial bands in Lu nuclei are analyzed using the configuration-constrained Cranked Nilsson-Strutinsky (CNS) model. Special attenti…
Achievable Rate Regions for the Dirty Multiple Access Channel with Partial Side Information at the Transmitters
Elham Bahmani, Ghosheh Abed Hodtani
In this paper, we establish achievable rate regions for the multiple access channel (MAC) with side information partially known (estimated or sensed version) at the transmitters. A…
Magnetized Kelvin-Helmholtz instability in the presence of a radiation field
Mohsen Shadmehri, Zahra Enayati, Mahdi Khajavi
The purpose of this study is to analyze the dynamical role of a radiation field on the growth rate of the unstable Kelvin - Helmholtz (KH) perturbations. As a first step toward thi…
S-matrix elements from T-duality
Komeil Babaei Velni, Mohammad R. Garousi
Recently it has been speculated that the S-matrix elements satisfy the Ward identity associated with the T-duality. This indicates that a group of S-matrix elements is invariant un…
