Comparative Study of Active Power Curtailment Methods of PVs for Preventing Overvoltage on Distribution Feeders
(IEEE, 2018)Overvoltage is one of the major issues on distribution grids with high penetration of photovoltaic (PV) generation. Overvoltage could be prevented through the control of active/reactive power of PVs. However given the high ... -
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 ... -
A Comparative Study of Metaheuristic Algorithms for Wave Energy Converter Power Take-Off Optimisation: A Case Study for Eastern Australia
(MDPI, 2021)One of the most encouraging sorts of renewable energy is ocean wave energy. In spite of a large number of investigations in this field during the last decade, wave energy technologies are recognised as neither mature nor ... -
A comparative study of surrogate based learning methods in solving power flow problem
(IEEE, 2020)Due to increasing volume of measurements in smart grids, surrogate based learning approaches for modeling the power grids are becoming popular. This paper uses regression based models to find the unknown state variables ... -
A comparative study of Turkhish and American activist theatre in the 20th century
(Kadir Has Üniversitesi, 2008)The essential goal of this project is two-fold: to gain a greater understanding of the role of activist theater in Turkey and in the U.S and discuss the need for activist theater. The research component of this project ... -
A Comparative Study on Denoising from Facial Images Using Convolutional Autoencoder
(Gazi Universitesi, 2023)Denoising is one of the most important preprocesses in image processing. Noises in images can prevent extracting some important information stored in images. Therefore, before some implementations such as image classification, ... -
Comparing efficiency in all-inclusive and bed and breakfast hotel businesses: a multi-period data envelopment analysis in Turkey
(Emerald Publishing, 2022)Purpose: This paper aims to understand the most efficient hotel system and why efficiency varies across years and between the two differing types of hotel businesses in Turkey. Design/methodology/approach: A data envelopment ... -
Comparing task-based instruction and traditional instruction on task engagement and vocabulary development in secondary language education
(Routledge Journals Taylor & Francis Ltd, 2018)The purpose of this study was to investigate and compare the impact of task-based instruction (TBI) and traditional instruction (TI) on the motivation and vocabulary development in secondary language education. The focus ... -
Comparison and analysis of various indoor positioning systems techniques
(Kadir Has Üniversitesi, 2016)indoor Positioning has been a research subject in order to facilitate people life easier. Different type of methods has been implemented and tested by the years. The Global Positioning System (GPS) is a satellite based ... -
Comparison of cation effects on phase transitions of kappa and iota carrageenan
(European Polymer Federation, 2010)Phase transitions of kappa and iota carrageenan in KCl NaCl and CaCl2 solutions were separately studied during heating and cooling processes by using fluorescence technique. Scattered light I-SC and fluorescence intensity ... -
Comparison of Compressed Sensing Based Algorithms for Sparse Signal Reconstruction
(IEEE, 2016)Compressed sensing theory shows that any signal which is defined as sparse in a given domain can be reconstructed using fewer linear projections instead of using all Nyquist-rate samples. In this paper we investigate basis ... -
Comparison of Cost-Free Computational Tools for Teaching Physics
(IEEE, 2010)It is widely accepted that it is quite difficult to engage today's students, from high schools to university, both in educational activities in class and "teaching" them physics due to their prejudices about the complexity ... -
Comparison of Earliest and Later Autobiographical Memories in Young and Middle-Aged Adults
(Istanbul Univ, 2019)The current study examined earliest memories of young and middle-aged adults in comparison to a recent autobiographical memory and a free-report one from any life phase. These three types of memories were compared in terms ... -
A comparison of erythrocyte superoxide dismutase and catalase activity in patients with hepatitis C infection
(2002)Hepatitis C virus (HCV) infection remains important due to difficulties in treatment up to a chronic state. It is considered that free radicals, lipid peroxidation and antioxidant defense play a role in various tissue ... -
