Today’s digital era relies heavily on data centers to house and handle massive volumes of data. Energy usage and heat control are two major issues that have become more difficult for data centers to deal with as data processing demands rise. To keep temperatures at safe levels and avoid machinery breakdown, reliable cooling systems are essential. The use of thermal chambers has become more i...
Introduction: Virtual reality (VR) development has been very beneficial to many other industries, including but not limited to the gaming business, the entertainment industry, the building industry, and the design industry. As virtual reality experiences become more immersive, the role of lighting design in the process of developing realistic and engaging virtual worlds is growing in importance. G...
Introduction: Measurement and characterisation of visible light sources is a typical use for goniophotometers. However, their functionality goes beyond what the human eye can see, allowing for the evaluation of UV and IR light sources. In this piece, we’ll look at how goniophotometers may be used for spectral measurements beyond the visible spectrum. Researchers, engineers, and manufacturers...
Introduction As the globe moves toward cleaner and more sustainable methods of electricity production, the renewable energy industry is seeing enormous development and innovation. The development and testing of renewable energy technologies, such as solar panels, wind turbines, energy storage systems, and fuel cells, need extensive examination under a wide range of environmental circumstances. The...
