Optical Spatial Modulation OFDM System Design [Optik Uzaysal Modülasyonlu OFDM Sistem Tasarımı]
(Institute of Electrical and Electronics Engineers Inc., 2016)In this paper a new optical orthogonal frequency division multiplexing (OFDM) method is proposed for multiple-input multiple-output (MIMO) visible light communications (VLC) systems. In the new scheme non-DC biased optical ... -
Optimal Allocation Of Multi-Type Distributed Generators For Minimization Of Power Losses In Distribution Systems
(Institute of Electrical and Electronics Engineers Inc., 2019)Distributed generation (DG), including photovoltaics (PVs), wind turbines (WTs) are becoming vital for Active Distribution Networks (ADN). Therefore, optimal sizing and allocation of these units can improve voltage profiles ... -
Optimization Model for Distributed Routing for Disaster Area Logistics
(IEEE, 2009)The problem of transportation in a disaster area can be seen broadly as having two aspects: (a) moving people and materials out of an area and (b) moving people and materiel into the same area. The common thread here is ... -
Optimization of Graph Affinity Matrix with Heuristic Methods in Dimensionality Reduction of Hypespectral Images
(IEEE, 2019)Hyperspectral images include hundreds of spectral bands, adjacent ones of which are often highly correlated and noisy, leading to a decrease in classification performance as well as a high increase in computational time. ... -
Optimizing NEURON Brain Simulator With Remote Memory Access On Distributed Memory Systems

Outage Probability of a Cooperative Maximum Ratio Transmission
(IEEE, 2014)In this paper we present a cooperative communication system employing maximum ratio transmission technique and its outage probability performance over Rayleigh fading channels. Since maximum ratio transmission can achieve ... -
Oxygen Diffusion into Polymer-Clay Composite Films as a Function of Clay Content and Temperature
(Wiley-VCH Verlag GmbH, 2009)A simple fluorescence technique is proposed for the measurement of the diffusion coefficient of oxygen into polystyrene-clay composite films as a function of clay content and temperature. The composite films were prepared ... -
Panel Data Analysis of Foreign Direct Investment and Poverty from the Perspective of Developing Countries
(Elsevier Science, 2014)The purpose of this paper is to assess the relationship between foreign direct investment (FDI) and poverty at the macro-pathway in selected developing countries. The contribution to host countries from FDI can take several ... -
Parallel Contingency Analysis Using Differential Evolution Based Solution For Branch Outage Problem
(IEEE, 2010)Contingency analysis is one of the most fundamental work an electricity management center operator has to perform regularly. If both bus voltage magnitudes and reactive power flowing on the branches during any type of ... -
