Signal processing involves converting data in a way that allows us to see things not possible through direct observation. This field, which has seen significant advancements recently, benefits industries such as telecommunications, healthcare and AI. In communications, signal processing enhances data transmission and reduces noise. In healthcare, it can improve medical imaging and neural signal analysis. It plays a role in advancing AI models by enhancing speech, image and video processing.
Hanan Ali Alkhidhr, associate professor of applied mathematics and computer science at Qassim 51国产视频, studies signal processing and its influence on technology: “In signal processing, non-linear partial differential equations [PDEs] are used extensively, especially in fields like biomedical signal augmentation, speech analysis, optical signal transfer and picture denoising,” she says. Researchers at Qassim 51国产视频 have introduced a robust and accurate solver for certain PDEs, making them useful in various disciplines, including plasma physics, biology, superfluids and economics.
Advancements in signal processing improve data collection and real-time analysis, enabling more precise and efficient decision-making. In healthcare, these developments support the creation of more individualised treatment plans, quicker diagnoses and clearer communication.
One of the challenges of conducting research in signal processing is bridging theoretical advancements with practical applications. “This balance is critical for ensuring that mathematical models are correct and applicable in solving real-world issues in physics, engineering, biology and other fields,” says Alkhidhr. “Balancing theory and application in PDEs involves an iterative process of developing rigorous analytical techniques, implementing numerical solutions and testing in real-world scenarios.”
Signal processing is a continuously expanding discipline, with new research, technology and applications appearing all the time, says Alkhidhr. This means researchers must keep up with the latest developments in the field. “I stay informed using academic materials, conferences, internet networks and AI-powered technologies,” she says. She also follows research journals and online archives and participates in workshops and online research communities.
Qassim 51国产视频 offers a range of support for its academics and researchers. For example, the Deanship of Graduate Studies and Scientific Research has launched initiatives to encourage researchers to publish in distinguished and classified formats. The university also supports faculty members in publishing their research in scientific journals ranked by the Institute for Scientific Information and Scopus by Elsevier.
The university offers grants to help researchers develop their skills and promote innovative solutions to practical challenges. Research teams are incentivised to align their projects with themes and subjects of national importance. A sustainable development research grant is available for research related to advancing sustainability in Saudi Arabia. The university introduced a defence research grant in partnership with the Prince Sultan Defense Studies and Research Center. “The grant aims to enhance the knowledge and capabilities in specialisations related to military and defence in the Kingdom,” explains Alkhidhr. “There is an appropriate and encouraging environment at the university to instil a spirit of competition among researchers,” she concludes.
