Performance Enhancement of Cognitive Radio Spectrum Sharing (CRSS) with MIMO System
Abstract: A key challenge in operating cognitive radios (CRs) in a self-organizing (ad hoc) network is to adaptively and efficiently allocate transmission powers and spectrum among CRs according to the surrounding environment. Cognitive radio networks will provide high bandwidth to mobile users via heterogeneous wireless architectures and dynamic spectrum access techniques. CR networks inflict challenges due to the fluctuating nature of the available spectrum, as well as the diverse QoS requirements …

Case Control Analysis on Neurodegeneration Disorders and Autism in Familial Context
Abstract: Neurodegenerative disorders such as Parkinson's and Alzheimer's co-occur with autism spectrum disorder (ASD), indicating shared genetic factors. Oxidative stress and inflammation play roles, with an elevated risk of Parkinson's and dementia in individuals with autism spectrum disorder. Antioxidant levels are linked to language and behaviour in autistic children. In the present study, a systematic review and meta-analysis was done following the PRISMA guidelines, reviewing English articles (2002- 2022) on familial …

Autonomous 6G Physical Layer Architectures for Space-Air-Ground Integrated Networks
Abstract: The emergence of sixth generation (6G) wireless systems calls for a significant shift away from conventional deterministic communication models. As communication infrastructures evolve into Space- Air-Ground Integrated Networks (SAGIN), traditional physical layer (PHY) techniques struggle to operate effectively under the severe Doppler effects and long propagation delays associated with space environments. This paper examines the role of artificial intelligence embedded directly within the 6G transceiver architecture to enable ultra-reliable and …

Birdwatcher’s Assistant: AI- Based Bird Species Classification
Abstract: Many bird species have gone extinct because of human activities and changes in the climate. The loss of habitats is a significant danger to global biodiversity. Therefore, it is important to monitor species distribution and identify the components of biodiversity in an area to develop conservation strategies. The ultimate objective is to build a machine learning model that can accurately differentiate between various bird species based solely on visual cues. …

Structures and sensors of Polymer Optical Fibers for Last Mile Networks
Abstract: Originating from distinct concepts for transferring information, sensing, or lighting efficiency, fiber characteristics vary greatly throughout their range. A substantial bandwidth-length product with acceptable attenuation characteristics is required for effective transfer of information. Since sensor fibers are typically used over short distances having considerably lower attenuation prerequisites. This paper presents polymer optical fiber (POFs) structures that are used as sensors over conventional fiber optics.An even broader spectrum of optical characteristics …
