An active sunlight redirection system for daylight enhancement beyond the perimeter zone
(2017)Over the past years, extensive research has been carried out in the creation of working environments that utilize natural light as their primary source of illumination. Transferring glare-free daylight into the core of the ... -
An Autonomous Illumination System for Vehicle Documentation Based on Deep Reinforcement Learning
(2021)A common problem for machine vision applications is uncontrolled illumination conditions that cause undesired artifacts on sensorial data. For instance, quality inspection using color cameras, while having wide industrial ... -
The effect of the daylight zone on lighting energy savings
(2020)Daylighting is the cornerstone of low energy building design. Therefore, the adoption of a daylight - harvesting lighting control system can substantially increase lighting energy savings. These are strongly depended on ... -
Estimating the benefits of increasing the recycling rate of lamps from the domestic sector: Methodology, opportunities and case study
(2020)The scope of this paper is to identify the benefits of lamp recycling from the domestic sector. Data related to the recycled lamps was obtained from two recycling companies and were compared to those related to the waste ... -
Harvesting daylight with LED or T5 fluorescent lamps? The role of dimming
(2017)While the efficiency of the Lighting Emitting Diodes (LED) is increasing and new installations are being implemented, their control due to the adoption of daylight harvesting systems, hasn't been sufficiently examined yet, ... -
The impact of energy efficiency indicators on the office lighting planning and its implications for office lighting market
(2019)Office lighting planners are faced with two key objectives as their plans should meet customers' needs and also be compliant with a range of policy guidelines targeted on a wide variety of lighting attributes. In the EU, ... -
Investigation of speed and trajectory of motorcycle riders at curved road sections of two-lane rural roads under diverse lighting conditions
(2021)Introduction: Vehicular accidents at horizontal curves are over-represented compared to accidents that occur at tangent sections. Investigations have been conducted aimed at identifying the major causes that result in ... -
Minimizing lighting consumption in existing tunnels using a no-cost fine-tuning method for switching lighting stages according revised luminance levels
(2019)Visual adaptation demands increased illuminance in the tunnel entrance, which results in an increased number of installed luminaires and power consumption of each luminaire. There are norms that define the required luminance ... -
Revision of threshold luminance levels in tunnels aiming to minimize energy consumption at no cost: Methodology and case studies
(2020)Because of the absence of lighting calculation tools at the initial stage of tunnel design, the lighting systems are usually over-dimensioned, leading to over illumination and increased energy consumption. For this reason, ... -
Simulating the impact of daytime calibration in the behavior of a closed loop proportional lighting control system
(2021)A daylighting control system that uses the closed loop proportional algorithm needs to be calibrated both during nighttime and daytime. The selection of the daytime calibration time can affect the behavior of the system ... -
Solar lighting
(2020)In this chapter information about solar lighting, façade systems, light-shelves, blinds, holographic optical elements, and daylight transfer systems are given. © Springer Nature Switzerland AG 2020. -
Voice interactive personalized security (VoIPSEC) protocol: Fortify internet telephony by providing end-to-end security through inbound key exchange and biometric verification
(2006)Secure end-to-end information exchange is a constant challenge in electronic communications. Novel security architectures and approaches are proposed constantly, to be followed by announcements of sophisticated attack ...
