Abstract:
Recently, transformers have demonstrated notable improvements in natural advanced visual tasks. In the field of computer vision, transformer networks are beginning to supplant conventional convolutional neural networks (CNNs) due to their global receptive field and adaptability. Although transformers excel in capturing global features, they lag behind CNNs in handling fine local features, especially when dealing with underwater images containing complex and delicate structures. In order to tackle this challenge, we propose a refined transformer model by improving the feature blocks (dilated tr

Abstract:
AbstractCoronal loops form the basic building blocks of the magnetically closed solar corona yet much is still to be determined concerning their possible fine-scale structuring and the rate of heat deposition within them. Using an improved multi-stranded loop model to better approximate the numerically challenging transition region, this article examines synthetic NASA Solar Dynamics Observatory’s (SDO) Atmospheric Imaging Assembly (AIA) emission simulated in response to a series of prescribed spatially and temporally random, impulsive and localised heating events across numerous sub-loop elem

Abstract:
In wideband wireless communication systems, the relative motion of the transmitter, receiver, or scatterers in the medium causes the Doppler effect, which stretches or compresses the transmitted waveforms, resulting in inter-symbol interference and a consequent severe performance degradation. To counter this, specialized transmitter and receiver architectures are needed for energy- and spectrally-efficient communications in channels characterized by path-dependent delays and time-scales. In this thesis, we develop and evaluate improved receiver side signal processing algorithms for two existin
