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. ...
An Efficient Architecture of Adder Using Fault-Tolerant Majority Gate Based on Atomic Silicon Nanotechnology
(Institute of Electrical and Electronics Engineers Inc., 2023)
It is expected that Complementary Metal Oxide Semiconductor (CMOS) implementation with ever-smaller transistors will soon face significant issues such as device density, power consumption, and performance due to the ...
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 ...
Novel azole-urea hybrids as VEGFR-2 inhibitors: Synthesis, in vitro antiproliferative evaluation and in silico studies
(Elsevier B.V., 2023)
The vascular endothelial growth factor receptor-2 (VEGFR-2) is a receptor tyrosine kinase known to be abnormally expressed in various malignant tumors, including breast cancer, and is considered one of the most important ...
A Framework to Forecast Electricity Consumption of Meters using Automated Ranking and Data Preprocessing
(Econjournals, 2023)
Forecasting electricity consumption is crucial for the operation planning of distribution companies and suppliers and for the success of deregulated electricity markets as a whole. Distribution companies often need consumption ...
