Directional illumination is critical for next-generation solid-state lighting. In this study, we demonstrate that flexible nanoantenna stickers enhance photoluminescence (PL) directionality. By integrating YAG:Ce phospho...

ABSTRACT Analysing learners' facial expressions during learning and exploring their learning processes and emotional changes are of great significance for assisting teachers' teaching and promoting smart education. In co...

Face-recognition technology is one of the most important advancements in the field of computer vision. They play a crucial role in many applications, including biometric authentication, surveillance, online security, and...

PbS colloidal quantum dots (CQDs) can be considered a promising lighting material, but their emission performance is mired by defect sites, strong photo-induced activity, and interaction with the environment. Here, we ut...

Abstract Strong lighting from above is common in everyday environments and this statistical regularity has shaped the function of the human visual system. Here we investigate the influence of vertical asymmetries in illu...

In this research, we have developed an approach by incorporating quantum dots (QDs) with red emission into mesoporous silica microspheres through a non-chemical process and obtained luminescent microspheres (LMS). Owing ...

Office buildings have frequently changed from the past to the present due to historical factors (the collapse of empires, colonialism and expansionist policies, the industrial revolution, wars, the development of technol...

Abstract Sun glare during sunrise and sunset and headlight glare at night can temporarily reduce contrast sensitivity and hazard detection, creating high risk driving conditions that contribute to severe crashes on speci...

ABSTRACT Background Halfway through the final decade of actions towards the 2030 Sustainable Development Goals (SDGs), progress toward SDG7 is off track. It is estimated that by 2030, 660 million people, mainly rural pop...

Introduction: Visual shade matching has been practiced in dentistry for decades to find a shade of restoration that perfectly match with adjacent tooth for natural aesthetic look. Intraoral camera is an adjunct tool for ...

IntroductionToday, the rapid acceleration of urbanization has made it necessary to reconsider the balance among energy consumption, environmental sustainability, and quality of life. Buildings, which account for a signif...

LED type bulb light is generally widely used in building spaces in Indonesia today because it is more energy efficient than other types. The purpose of this study is to utilize the light bulb as a new photon energy sourc...

Abstract Background Most households in developing countries like India are not able to afford to get the services of efficient energy for cooking and lighting. Therefore, they rely mostly on solid fuels (firewood, dung c...

This paper focuses on control systems for hybrid heat pumps that utilize the heat from return heat-ing water and outdoor air, designed to operate in district heating systems based on central heating plants. The aim of th...

This study presents a comprehensive approach to nail condition classification using multi-illumination imaging and uncertainty-aware deep learning. We developed a diagnostic system capturing nail images under ten lightin...

On-chip nanophotonic devices are a class of devices capable of controlling light on a chip to realize performance advantages over ordinary building blocks of integrated photonics. These ultra-fast and low-power nanoscale...

In December 2020, the Federal Aviation Administration (FAA) announced the release of a new final rule, permitting operators of small unmanned aircraft systems (sUAS) to perform routine night operations. Public comments t...

Face-based attendance systems are increasingly popular for their ease of use, but they are susceptible to fraud, such as using photos or videos for unauthorized attendance. This study introduces a digital attendance syst...

Complex interactions between seawater and freshwater govern intrusion and stabilization in coastal aquifers. Previous studies have primarily relied on interface-based analyses, limiting full-field spatial quantification ...

The rapid proliferation of unmanned aerial vehicles (UAVs) has created an urgent need for robust detection & identification systems to ensure airspace security and safety. However, the scarcity of large-scale, div...
