On the analysis of expected distance between sensor nodes and the base station in randomly deployed WSNs
(Springer Verlag, 2014)In this study, we focus on the analytical derivation of the expected distance between all sensor nodes and the base station (i.e., E[dtoBS]) in a randomly deployed WSN. Although similar derivations appear in the related ... -
On the identification of microstretch elastic moduli of materials by using vibration data of plates
(Pergamon-Elsevier Science LTD, 2008-06)In the present work, the vibration problems of rectangular plates modeled by Eringen's microstretch theory are investigated for the identification of the upper bounds of the microstretch moduli of the plate material. The ... -
Optimal deployment in randomly deployed heterogeneous WSNs: A connected coverage approach
(Academic Press Ltd- Elsevier Science Ltd, 2014-11)Wireless sensor networks (WSNs) are resource-scarce networks and the optimization of the resources is challenging. As far as random deployment is concerned, the optimization of these resources becomes even more difficult ... -
Optimal deployment in randomly deployed heterogeneous WSNs: A connected coverage approach (vol 46, pg 182, 2014)

A parallel implementation: Real space Green's function technique
(Sage Publications, 2007-04)We develop an MPI-based parallel algorithm to implement the real space Green's function technique for calculating the vibrational density of states corresponding to a solid. The Hamiltonian describing the interactions ... -
Parameter estimation with Dzyaloshinskii–Moriya interaction under external magnetic fields
(Springer, 2020-02-01)We study the effects of external magnetic fields on the precision of parameter estimation with thermal entanglement of two spins in XX model, in the presence of Dzyaloshinskii–Moriya (DM) interaction. Although DM interaction ... -
Phase damping destroys quantum Fisher information of W states
(Elsevier Science BV, 2014-09-05)We study the quantum Fisher information (QFI) of W states in the basic decoherence channels. We show that, as decoherence starts and increases, under i) depolarizing, QFI smoothly decays; ii) amplitude damping, QFI first ... -
Photogrammetric monitoring of an artificially generated landslide
(Copernicus GmbH, 2011-05-08)According to pre-planned schedules, a series of two artificial rainfall events were applied to a forested slope in Ruedlingen, northern Switzerland. The experiments were conducted in autumn 2008 and spring 2009, the second ... -
Preparing multipartite entangled spin qubits via pauli spin blockade
(Nature Research, 2020-02-26)Preparing large-scale multi-partite entangled states of quantum bits in each physical form such as photons, atoms or electrons for each specific application area is a fundamental issue in quantum science and technologies. ... -
Primitives of service oriented information system development
(2011)One can find the long standing problems with conceptual modeling such as model transformation, reusability and agility in the classical information system development (ISD). New approaches may help in overcoming these ... -
Quantum fisher information of a 3 x 3 bound entangled state and its relation with geometric discord
(Springer/Plenum Publishers, 2015-09)Recent studies on quantum Fisher information (QFI) have been focused mostly on qubit systems within the context of how entanglement helps surpassing the classical limit of separable states and the limit that a given entangled ... -
Quantum fisher information of bipartitions of W states
(Polish Acad Sciences Inst Physics, 2015-04-24)We study the quantum Fisher information (QFI) of W states and W-like states under decoherence. In particular, we find that on the contrary to amplitude damping and depolarizing decoherence, a W-like state of 3 qubits ... -
Quantum fisher information of several qubitsin the superposition of A GHZ and two W stateswith arbitrary relative phase
(Springer/Plenum Publishers, 2014-09)We study the quantum Fisher information (QFI) of a system of several particles which is in a superposition of a GHZ and two W states with arbitrary relative phase. We show that as the number of particles increases from 3 ... -
Quantum metrology: Surpassing the shot-noise limit with Dzyaloshinskii-Moriya interaction
(Nature Publishing Group, 2015-11-09)Entanglement is at the heart of quantum technologies such as quantum information and quantum metrology. Providing larger quantum Fisher information (QFI), entangled systems can be better resources than separable systems ... -
Quarantine region scheme to mitigate spam attacks in wireless sensor networks
(IEEE, 2006-08)The Quarantine Region Scheme (QRS) is introduced to defend against spam attacks in wireless sensor networks where malicious antinodes frequently generate dummy spam messages to be relayed toward the sink. The aim of the ... -
Querying sensor networks by using dynamic task sets
(Elsevier B.V., 2006-05-15)A data querying scheme is introduced for sensor networks where queries formed for each sensing task are sent to task sets. The sensor field is partitioned into subregions by using quadtree based addressing, and then a given ... -
