Optimization of graph affinity matrix with heuristic methods in dimensionality reduction of hypespectral images
(Institute of Electrical and Electronics Engineers Inc., 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. ...
Amplitude and frequency modulation behaviours of cellular neural networks
(2012)
As is well known, Amplitude Modulation (AM) and Frequency Modulation (FM) are the most popular modulation techniques in communications [1]. Classically, they are designed as individual systems at transmitters; however in ...
MP-SAGE based channel estimation for underwater cooperative OFDM systems
(2013)
In this paper, an efficient ehannel estimation algorithm is proposed fOl' amplify-And-forward (AF) eooperative relay based orthogonal fl'equency division multiplexing (OFDM) system in the presenee of sparse underwater ...
Transmit precoding for physical layer security of MIMO-NOMA-based visible light communications
(VDE Verlag GmbH, 2021)
We consider the physical layer security (PLS) of non-orthogonal multiple access (NOMA) enabled multiple-input multiple-output (MIMO) visible light communication systems in the presence of a passive eavesdropper (Eve). In ...
A new technique for OFDM: OFDM-index modulation
(2013)
In this study, a novel scheme called orthogonal frequency division multiplexing with index modulation (OFDMIM) is proposed for frequency selective channels. In this scheme, the information is conveyed not only by only M-Ary ...
The Effect of Codebook Design on the Conventional SCMA System Performance
(Institute of Electrical and Electronics Engineers Inc., 2020)
In 4G systems, Orthogonal Frequency-Division Multiple Access (OFDMA) has been used conventionally for multiple access purposes. This technique has low spectral efficiency since it allocates the resources orthogonally to ...
Lead-like compounds for inhibiting Methionine amino peptidase 2 (MetAP2)
(IOP Publishing Ltd, 2021)
This research aims to find a new approach to deal with cancer, by targeting a protein that controls the growth and increases the size of the tumour. The approach uses computer-aid drug designed to find the best drug for ...
Investigation of Cyber Situation Awareness via SIEM tools: a constructive review
(Institute of Electrical and Electronics Engineers Inc., 2021)
Awareness, in the sense of security, builds the backbone of operations understanding the current and future cyber activities. Situation awareness has become the focal point of securing systems due to dynamic nature of cyber ...
Energy Loss Minimization with Parallel Implementation of Marine Predators Algorithm
(Institute of Electrical and Electronics Engineers Inc., 2021)
Distribution network (DN) service continuity is one of the significant issues in today's power systems. This paper aims to put a strategy for supplying loads with less discontinuity and affordable energy-consuming. The ...
GENeSYS-MOD Turkey: Quantitative Scenarios for Low Carbon Futures of the Turkish Energy System
(IEEE Computer Society, 2022)
This paper examines the quantitative scenarios for low-carbon futures of the Turkish energy system at aggregated (country level) and regionally disaggregated (NUTS-1 level) levels. We have employed four different storylines ...
