Identifying inter-area oscillations can be a challenge for interconnected grids. Two identifier algorithms (FBMSWA and TBR-EMD) proposed to detect these oscillations are comparatively tested in this research. FBMSWA is implemented with T-STATCOM to damp out 0.15 Hz low-frequency inter-area oscillation after interconnection Turkey with ENTSO-E. Developed TBR-EMD algorithm has certain achievements, e.g. admissible for real time, handling intermittency problem of EMD, proved by real data.

Design and evaluation of V-shaped arrays for 2-D DOA estimation
Filik, Tansu; Tuncer, Temel Engin (2008-04-04)
A new method for optimum design of V-shaped arrays is presented for azimuth and elevation angle estimation simultaneously. The design criterion is based on the Cramer-Rao Bound (CRB) for joint estimation where the coupling effect between the azimuth and elevation direction of arrival (DOA) angles is taken into account. The design method finds an optimum angle between the linear sub-arrays of the V-array. The computation of the optimum angle is simple due to the monotonic characteristics of the best and wors...
Modeling of the nonlinear behavior of steel framed structures with semi rigid connections
Sarıtaş, Afşin; Özel, Halil Fırat (null; 2015-07-21)
A mixed formulation frame finite element with internal semi-rigid connections is presented for the nonlinear analysis of steel structures. Proposed element provides accurate responses for spread of inelasticity along element length by monitoring the nonlinear responses of several crosssections, where spread of inelasticity over each section is captured with fiber discretization. Each material point on the section considers inelastic coupling between normal stress and shear stress. The formulation of the ele...
Analysis and design of conformal frequency selective surfaces /
Dalkılıç, Akın; Alatan, Lale; Department of Electrical and Electronics Engineering (2014)
An efficient analysis and design approach for conformal frequency selective surface (FSS) structures is developed. The design methodology involves the analysis of both the planar and curved FSS structures. First, planar unit cell analysis of conformal FSS models are accomplished for normal and oblique incidence cases. To prove conformal applicability of planar designs, a semi-finite analysis method is utilized. This method is based on solution of a singly periodic curved FSS structure of semi-cylinder shape...
Development of free and open source software for flow mapping integrated to geographic information systems
Güllüoğlu, Naim Cem; Işık, Oğuz; Karahanoğlu, Nurkan; Department of Geodetic and Geographical Information Technologies (2014)
Mapping of spatial interaction data is an ongoing challenge for cartographers. In many Geographic Information Systems (GIS) software there is no off-the-shelf functionality for processing and visualizing spatial interactions or geographical flows. Considering the development efforts that have been made in the last few decades to discover the potential of GIS almost in every aspect, handling and visualization of spatial interaction data under GIS remain underutilized. The main objective of this study is to d...
Consideration of spatial variation of the length scale parameter in static and dynamic analyses of functionally graded annular and circular micro-plates
Eshraghi, Iman; Dağ, Serkan; Soltani, Nasser (2015-09-01)
This article introduces new methods for static and free vibration analyses of functionally graded annular and circular micro-plates, which can take into account spatial variation of the length scale parameter. The underlying higher order continuum theory behind the proposed approaches is the modified couple stress theory. A unified way of expressing the displacement field is adopted so as to produce numerical results for three different plate theories, which are Kirchhoff plate theory (KPT), Mindlin plate t...
