Wireless Sensing in Complex Electromagnetic Media: Construction Materials and Structural Monitoring
Ozbey, Burak; DEMİR, Hilmi Volkan; Kurç, Özgür; ERTÜRK, VAKUR BEHÇET; ALTINTAŞ, AYHAN (2015-10-01)
In this paper, wireless sensing in the presence of complex electromagnetic media created by combinations of reinforcing bars and concrete is investigated. The wireless displacement sensing system, primarily designed for use in structural health monitoring (SHM), is composed of a comb-like nested split-ring resonator (NSRR) probe and a transceiver antenna. Although each complex medium scenario is predicted to have a detrimental effect on sensing in principle, it is demonstrated that the proposed sensor geome...
Cooperative Localization In One-Hop And Multi-Hop Wireless Sensor Networks Using Alternating Minimization Algorithm
Erdemir, Ece Naz; Tuncer, Temel Engin (2016-05-19)
In this work, a new approach is proposed to solve cooperative localization problems in wireless sensor networks for both one-hop and multi-hop cases. To find the unknown positions of randomly distributed sensors with limited power and communication ability, noisy inter-sensor distances and anchor node positions are used. In a plane, when the distances between a sensor and at least three neighbor anchors are known, it is possible to find the sensor position by solving a linear set of equations. However, for ...
Nonlinear optical properties of a Poschl-Teller quantum well under electric and magnetic fields
AYTEKİN, ÖZLEM; Turgut, Sadi; Tomak, Mehmet (2012-04-01)
The nonlinear optical properties of a Poschl-Teller Quantum well (PTQW) under electric and magnetic fields are studied. The salient feature of this potential is its flexibility. It can be made asymmetrical by a proper choice of its two parameters. Optical rectification, second and third-harmonic generation susceptibilities are calculated using the density matrix formalism. We study the effects of quantum confinement, electric and magnetic fields on all of these optical coefficients.
Cooperative relaying schemes for narrow-band frequency hopping wireless ad hoc networks
Yenihayat, Güven; Onat, Furuzan Atay; Kolaǧasioǧlu, Ertuǧrul; Yılmaz, Ali Özgür (2011-08-29)
Cooperative relaying is a promising technique for improving the performance of weak communication links in wireless networks by exploiting spatial diversity induced by relay transmissions. This paper considers cooperative relaying schemes for a narrow- band frequency hopping system. A novel hybrid relaying scheme called opportunistic hybrid relaying, which is specifically designed for this system, is presented. Unlike most relaying schemes in the literature, opportunistic hybrid relaying uses bandwidth effi...
Pseudo-Dynamic Testing and Analytical Modeling of AAC Infilled RC Frames
Sucuoğlu, Haluk (2014-01-01)
Two concrete frames were tested by the PsD procedure. One frame was bare and the other was infilled with AAC blocks in the middle bay. The objective was to determine the effect of AAC infills on the seismic performance of reinforced concrete frames and developing an AAC strut model. Based on the test results, it was found that AAC infill panels did not modify the deformation response of the RC test frame significantly; however, shear in diagonal strut must be considered in boundary column design. A shear de...
