FPGA-Based Acoustic Feedback Suppression A Review of Algorithms, Implementations, and Future Directions
Sonar Acoustic feedback remains a critical limitation in sound reinforcement and communication systems, particularly in environments where microphones and loudspeakers operate close proximity. Traditional suppression methods such as notch filtering, phase shifting, and frequency shifting provide partial relief but often introduce latency, tonal coloration, and reduced audio quality. Recent work has increasingly explored adaptive approaches …
A Comprehensive Review of Vision-Based and Data-Driven Solar Power Forecasting Techniques
The increasing penetration of large-scale photovoltaic power plants has intensified the challenge of managing power variability caused by rapid changes in solar irradiance. Short term and ultra short-term power fluctuations, mainly driven by cloud movement, can lead to severe ramp rate violations and grid instability, particularly in weak and island power systems. This review critically …

The Role of IMF in Restoring the Financial Stability of Developing Countries in the Post-Pandemic Era: Case Study of Sri Lanka
The International Monetary Fund (IMF) is helping developing countries that the Covid-19 pandemic has inconvenienced. As a result, The International Monetary Fund (IMF) has approved a 48-month Extended Fund Facility(EFF) of about 3 billion USD to support Sri Lanka’s Covid-19 post-pandemic era. This IMF’s support impacts SriLanka’s economy, both directly and indirectly. Therefore, this research …
Comparative Life-Cycle and Performance Assessment of Fly Ash-Based Geopolymer Binders versus Ordinary Portland Cement for Energy-Efficient Building Applications
The construction industry is a major contributor to global CO2 emissions, primarily due to the energy-intensiveproduction of Ordinary Portland Cement (OPC). This paper presents a comparative case study comparing the environmental,mechanical, and durability performance of OPC (Conventional) and Fly Ash-Based Geopolymer Binders (Sustainable). Using data extracted from past research, this study demonstrates the significant sustainable …
Advances in Nano Filter Production Using Nanofibers
Nanofibers have emerged as revolutionary material for advanced filtration technologies, particularly for the development of high-performance nano filters for air and water purification. Due to their exceptional characteristics, namely a high surface area-to-volume ratio, high porosity, and controllable nanometer-scale pore size, nanofiber-based membranes significant lysurpass conventional filter media in filtration efficiency and flow rate. This …
