    Review On Hand Gesture Recognition for Bengali Sign Language
    (IEEE, 2022-04-14) Perera, D; Kanchana, B; Peiris, R; Madushan, K; Kasthurirathna, D
    Communication becomes difficult when interaction between the disabled and the general public are required. People with disabilities of various races communicate using various sign languages. For persons who are deaf or hard of hearing sign language is their primary mode of communication. However, the majority of our community does not understand sign language, taking them out in public is incredibly challenging. In order to make sign language understandable to the general public, computer vision-based methods are now widely used. Recognition of hand gesture is one of the computer vision based technologies for recognizing sign language, and it is attracting a lot of attention from analysis. For a long time, it has been a popular research area. In the area of hand gesture recognition in computer vision, some recent research has achieved outstanding improvements by employing deep learning techniques. In this paper we have discussed the previous research methods, technologies, datasets and models used in Bengal sign language gestures that are interconnected in terms of achieving a successful result. Therefore, this review article tried to reveal the independent techniques which are used to overcome the challenges in research.

    A Review of Geothermal Energy for Future Power Generation
    (IEEE, 2019-09-26) Kulasekara, H; Seynulabdeen, V
    Renewable power generation is rapidly increasing due to the depletion and unfavorable environmental impact of fossil fuels. Geothermal energy is a form of renewable energy that can be effectively used for electric power generation. Besides, geothermal power provides considerable advantages compared to other renewable resources such as solar and wind power. Geothermal energy provides reliable, stable and efficient power compared to the lack of inertia, lack of efficiency and the intermittent nature of solar and wind resources. Moreover, geothermal power plants must be integrated with energy storage devices to improve the stability and flexibility of the power system. Gravity-fed energy storage and flywheel energy storage systems are two reliable technologies that can be integrated with geothermal power for improved stability and flexibility. Furthermore, the disadvantages of geothermal energy such as higher initial cost and geographic dependency can be compensated using recent research and developments in the geothermal technology. These recent developments include enhanced geothermal systems, small-scale geothermal power generation and geothermal power generation using abandoned oil and gas wells. Therefore, geothermal energy has the potential to become a major power generating source in the future.
