DCT-OFDM tabanlı görünür ışık haberleşmesi
(2016)Visible light communication (VLC) is a short-range wireless transmission technique in which light emitting diodes (LEDs) are used as data transmitters. Because of non-coherent characteristics of LEDs, only intensity can ... -
Decision model and application of electric vehicle charger installation to distribution transformers
(IEEE, 2022)It is very evident that the number of electric vehicles worldwide will increase and that the dominant mobility concept in the future will be at the center of EVs. As a requirement of e-mobility, EVs should be rechargeable ... -
Deep learning based event recognition in aerial imagery
(IEEE, 2023)In this paper, we investigate event recognition for aerial surveillance. This is a significant task especially when we consider the growing popularity of UAVs. The main purpose of the paper is to detect events both at the ... -
Deep learning-based blind image super-resolution with iterative kernel reconstruction and noise estimation
(Elsevier, 2023-08)Blind single image super-resolution (SISR) is a challenging task in image processing due to the ill-posed nature of the inverse problem. Complex degradations present in real life images make it difficult to solve this ... -
Deep learning-based speaker-adaptive postfiltering with limited adaptation data for embedded text-to-speech synthesis systems
(Elsevier, 2023-06)End-to-end (e2e) speech synthesis systems have become popular with the recent introduction of text-to-spectrogram conversion systems, such as Tacotron, that use encoder–decoder-based neural architectures. Even though those ... -
Deep Q-learning based optimization of VLC systems with dynamic time-division multiplexing
(IEEE, 2020)The traditional method to solve nondeterministic-polynomial-time (NP)-hard optimization problems is to apply meta-heuristic algorithms. In contrast, Deep Q Learning (DQL) uses memory of experience and deep neural network ... -
Deep reinforcement based power allocation for the max-min optimization in non-orthogonal multiple access
(IEEE, 2020)NOMA is a radio access technique that multiplexes several users over the frequency resource and provides high throughput and fairness among different users. The maximization of the minimum the data-rate, also known as ... -
Delivery phase in cache-based wireless networks with modified LT codes
(Springer Nature, 2020-10)Caching has emerged as an efficient technique to reduce delivery latency and network congestion. The focus of this paper is on content delivery in the caching-based wireless systems. In view of the fact that in such systems, ... -
Demand-driven electricity supply options of electric vehicles: modelling, simulation, and management strategy of public charging stations
(Springer, 2021-10-13)In this chapter, we discuss the challenges and research opportunities in the demand-driven electricity supply options of electric vehicles (EVs) at public charging stations (CSs). EVs have gained increased attention in ... -
Depression screening from voice samples of patients affected by parkinson’s disease
(S. Karger AG, 2019-05-01)Depression is a common mental health problem leading to significant disability worldwide. It is not only common but also commonly co-occurs with other mental and neurological illnesses. Parkinson's disease (PD) gives rise ... -
Depression-level assessment from multi-lingual conversational speech data using acoustic and text features
(Springer Nature, 2020-11-17)Depression is a widespread mental health problem around the world with a significant burden on economies. Its early diagnosis and treatment are critical to reduce the costs and even save lives. One key aspect to achieve ... -
Design and analysis of a truncated elliptical-shaped chipless RFID tag
