In the frame of the European COST 296 project (Mitigation of Ionospheric Effects oil Radio Systems, MIERS) in the Working Package 1.3, new ionospheric models, prediction and forecasting methods and programs as well as ionospheric imaging techniques have been developed. They include (i) topside ionosphere and meso-scale irregularity models, (ii) improved forecasting methods for real time forecasting and for prediction of foF2, M(3000)F2, MUF and TECs, including the use of new techniques such as Neurofuzzy, Nearest Neighbour, Cascade Modelling and Genetic Programming and (iii) improved dynamic high latitude ionosphere models through tomographic imaging and model validation. The success of the prediction algorithms and their improvement over existing methods has been demonstrated by comparing predictions with later real data. The collaboration between different European partners (including interchange of data) has played a significant part in the development and validation of these new prediction and forecasting methods, programs and algorithms which call be applied to a variety of practical applications leading to improved mitigation of ionosphereic and space weather effects.

Potential Utilization of Building Information Models for Planning Maintenance Activities Akçamete Güngör, Aslı; Garrett, James H (2010-06-30) The opportunities for leveraging Building Information Models (BIMs) for facility operations are compelling and yet utilization of BIMs during building operation and maintenance is falling behind the BIM implementations for design and construction. Current studies of BIMs used for the operations phase and commercially available technologies focus on transferring information from the design and construction phases to the operations phase by enabling creation and capturing of digital facility information throu...
Non-parametric and semi-parametric regional modeling of the ionospheric vertical total electron content using ground-based GPS observations Durmaz, Murat; Karslıoğlu, Mahmut Onur; Department of Geodetic and Geographical Information Technologies (2013) Different global and regional models have been proposed for modeling of Vertical Total Electron Content(VTEC). Basis functions such as Spherical Harmonics and tensor products of univariate B-Splines are used for global and regional modeling respectively. The coefficients of the basis functions and Differential Code Biases (DCB) of satellites and receivers are treated as parameters and estimated from geometry-free linear combinations. In this work, a new approach based on non-parametric and semi-parametric m...
Local modeling of the ionospheric vertical total electron content (VTEC) using particle filter Aghakarimi, Armin; Karslıoğlu, Mahmut Onur; Department of Geodetic and Geographical Information Technologies (2012) Ionosphere modeling is an important field of current studies because of its influences on the propagation of the electromagnetic signals. Among the various methods of obtaining ionospheric information, Global Positioning System (GPS) is the most prominent one because of extensive stations distributed all over the world. There are several studies in the literature related to the modeling of the ionosphere in terms of Total Electron Content (TEC). However, most of these studies investigate the ionosphere in t...
Design and implementation of a sic based three phase grid-connected current source inverter for solar applications Bay, Olcay; Ermiş, Muammer; Bilgin, Hazım Faruk; Department of Electrical and Electronics Engineering (2017) In this thesis, analysis, design and implementation of a three-phase 400V, 20 kVA Current Source Inverter (CSI) have been carried out for grid-connected photovoltaic applications based on the multi-string inverter concept. This inverter can be used in large scale photovoltaic (PV) applications by connecting many in parallel at 400V and coupling to medium voltage through a common transformer. The power stage of the inverter is based on the basic full-bridge CSC topology and each power semiconductor which mus...
A MULTISCALE MODELING APPROACH TO UNDERSTAND MECHANISM OF DEPOSIT CONTROL BY LUBRICANT DETERGENTS AND DISPERSANTS Kan, Esra; Yıldırım, Erol; Department of Polymer Science and Technology (2022-7-29) With the recent developments in high performance computing power, molecular modeling calculations to design and improve new generation additives for engine oils have reached a level that can support and guide experimental results. Control of insoluble nanoparticle aggregations in oil and on the engine pistons is the most important key performance parameter for lubricant oil additives. General consensus about the mechanism of deposit build-up is the self-aggregation of nanosized insoluble structures. Deterge...
