A Review on the Applications of Machine Learning for Tinnitus Diagnosis Using EEG Signals
Tinnitus is a prevalent hearing disorder that can be caused by various
factors such as age, hearing loss, exposure to loud noises, ear infections or
tumors, certain medications, head or neck injuries, and psychological
conditions like anxiety and depression. While not every patient requires
medical attention, about 20% of sufferers seek clinical intervention. Early
diagnosis is crucial for effective treatment. New developments have been made
in tinnitus detection to aid in early detection of this illness. Over the past
few years, there has been a notable growth in the usage of
electroencephalography (EEG) to study variations in oscillatory brain activity
related to tinnitus. However, the results obtained from numerous studies vary
greatly, leading to conflicting conclusions. Currently, clinicians rely solely
on their expertise to identify individuals with tinnitus. Researchers in this
field have incorporated various data modalities and machine-learning techniques
to aid clinicians in identifying tinnitus characteristics and classifying
people with tinnitus. The purpose of writing this article is to review articles
that focus on using machine learning (ML) to identify or predict tinnitus
patients using EEG signals as input data. We have evaluated 11 articles
published between 2016 and 2023 using a systematic literature review (SLR)
method. This article arranges perfect summaries of all the research reviewed
and compares the significant aspects of each. Additionally, we performed
statistical analyses to gain a deeper comprehension of the most recent research
in this area. Almost all of the reviewed articles followed a five-step
procedure to achieve the goal of tinnitus. Disclosure. Finally, we discuss the
open affairs and challenges in this method of tinnitus recognition or
prediction and suggest future directions for research

WILDFIRE DETECTION SYSTEM BASED ON PRINCIPAL COMPONENT ANALYSIS AND IMAGE PROCESSING OF REMOTE-SENSED VIDEO
Early detection and mitigation of wildfires can reduce devastating property damage, firefighting costs, pollution, and loss of life. This thesis proposes the method of Principal Component Analysis (PCA) of images in the temporal domain to identify a smoke plume in wildfires. Temporal PCA is an effective motion detector, and spatial filtering of the output Principal Component images can segment the smoke plume region. The effective use of other image processing techniques to identify smoke plumes and heat plumes are compared. The best attributes of smoke plume detectors and heat plume detectors are evaluated for combination in an improved wildfire detection system. PCA of visible blue images at an image sampling rate of 2 seconds per image effectively exploits a smoke plume signal. PCA of infrared images is the fundamental technique for exploiting a heat plume signal. A system architecture is proposed for the implementation of image processing techniques. The real-world deployment and usability are described for this system
Image Processing Using FPGAs
This book presents a selection of papers representing current research on using field programmable gate arrays (FPGAs) for realising image processing algorithms. These papers are reprints of papers selected for a Special Issue of the Journal of Imaging on image processing using FPGAs. A diverse range of topics is covered, including parallel soft processors, memory management, image filters, segmentation, clustering, image analysis, and image compression. Applications include traffic sign recognition for autonomous driving, cell detection for histopathology, and video compression. Collectively, they represent the current state-of-the-art on image processing using FPGAs
Waveform Design for 5G and beyond Systems
5G traffic has very diverse requirements with respect to data rate, delay, and reliability. The concept of using multiple OFDM numerologies adopted in the 5G NR standard will likely meet these multiple requirements to some extent. However, the traffic is radically accruing different characteristics and requirements when compared with the initial stage of 5G, which focused mainly on high-speed multimedia data applications. For instance, applications such as vehicular communications and robotics control require a highly reliable and ultra-low delay. In addition, various emerging M2M applications have sparse traffic with a small amount of data to be delivered. The state-of-the-art OFDM technique has some limitations when addressing the aforementioned requirements at the same time. Meanwhile, numerous waveform alternatives, such as FBMC, GFDM, and UFMC, have been explored. They also have their own pros and cons due to their intrinsic waveform properties. Hence, it is the opportune moment to come up with modification/variations/combinations to the aforementioned techniques or a new waveform design for 5G systems and beyond. The aim of this Special Issue is to provide the latest research and advances in the field of waveform design for 5G systems and beyond
