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. ...
Reformulations of a Bilevel Model for Detection of Tacit Collusion in Deregulated Electricity Markets
(IEEE Computer Society, 2019)
In this study, we consider a collusion model for competitive pool based electricity markets operated by an independent system operator (ISO), where it aims to prevent tacit collusion among generators. In order to determine ...
Grey Wolf optimizer for allocation and sizing of distributed renewable generation
(Institute of Electrical and Electronics Engineers Inc., 2019)
Increasing penetration of distributed energy resources (DERs) have brought operational and control philosophy changes in Smart Grids (SGs). Renewable energy based technologies are becoming more important due to their ...
Active and Reactive Power Load Profiling Using Dimensionality Reduction Techniques and Clustering
(Institute of Electrical and Electronics Engineers Inc., 2019)
This paper proposes a methodology to characterize active and reactive power load profiles. Specifically, the approach makes use of fast Fourier Transform for conversion into frequency domain, principle component analysis ...
A Comparative Study of Energy Models for Turkish Electricity Market Using LEAP
(IEEE Computer Society, 2019)
Fossil fuel thermal power plants constitute a large part of the Turkish electricity generation capacity. Turkish government has been developing several energy policy documents to evaluate how various renewable energy sources ...
Multi-Sensor Indoor Positioning
(Institute of Electrical and Electronics Engineers Inc., 2019)
In this paper, the performance of three different kinds of Kalman Filter (KF) structure: Single Kalman Filter (SKF)(which filters data of a single sensor), Centralized Kalman Filter (CKF) and Federated Kalman Filter (FKF) ...
Is It Merely a Labor Supply Shock? Impacts of Syrian Migrants on Local Economies in Turkey
(Sage Publications, 2021)
The authors use the occurrence of a large and geographically varying inflow of more than 2.5 million Syrian migrants to Turkey between 2012 and 2015 to study the effect of migration on local economies. They do not find ...
Activist communication design on social media: The case of online solidarity against forced Islamic lifestyle
(Sage Publications, 2021)
This article explores the relationship between connective and collective group identity through the example of “You Won’t Walk Alone,” a social media platform of solidarity for women suffering from the pressures of Islamic ...
Overcoming the Egyptian cotton crisis in the interwar period: the role of irrigation, drainage, new seeds, and access to credit
(Blackwell Publishing, 2021)
After experiencing a period of spectacular growth during the late nineteenth century, the Egyptian cotton sector underwent a phase of stagnation, which was followed by a gradual and steady increase in output during the ...
A Dynamic Game Theory Model For Tourism Supply Chains
(Sage Publications, 2021)
This article contributes to the game-theoretic analysis of tourism supply chains. We start with a baseline model including three types of agents: (a) one theme park, (b) multiple accommodation providers, and (c) multiple ...
