In prior imaging systems [1-3], image artifacts may be caused by flickering lighting and objects with changing illumination in an image frame. Such artifacts may include, for example, missing parts of an object, edge color artifacts, and object distortion. Examples of objects with changing illumination include light-emitting diode (LED) traffic signs (which can flicker several hundred times per...
WAVO consists of a PoSC micro-computer, an accelerometer and a 16x16 matrix LED and express moving waves with LED. These waves are calculated by Wave Equation in real-time. Therefore, people can feel beautiful moving of lights which this equation makes. Yet, people can enjoy wave interaction as WAVO has an accelerometer. Interacting with people, this art work notices them fascinating aspects of...
Full spectra allow the generation of physically correct rendering of a scene under different lighting conditions. Here, a tool is developed to design a palette of lights and materials having certain properties, such as selective metamerism or colour constancy. The mathematical underpinnings of the tool consist of two parts. Firstly, we make use of a method for optimally characterizing full spec...
OBJECTIVES The main aim was to survey interactions between the public highway users and emergency ambulances using lights and sirens. The objectives were to identify negative and positive experiences, and to assess the frequency and consequences of these events. METHODS Because of a poor response from a random postal pilot, a quota sample of 200 was adopted with a response of 65%. This provid...
Objective Using Fourier transform infrared analysis (FTIR) in vitro, the effects of varying radiant exposure (RE) values generated by second and third generation LED LCUs on the degree of conversion (DC) and maximum rate of polymerization (Rpmax) of an experimental Lucirin TPO-based RC were evaluated. Material and Methods 1 mm or 2 mm thick silicon molds were positioned on a horizontal attenu...
This paper proposes a vehicle light detection method using a hyperspectral camera instead of a Charge-Coupled Device (CCD) or Complementary metal-Oxide-Semiconductor (CMOS) camera for adaptive car headlamp control. To apply Intelligent Headlight Control (IHC), the vehicle headlights need to be detected. Headlights are comprised from a variety of lighting sources, such as Light Emitting Diodes (...
Artificial lights at night cause high mortality of seabirds, one of the most endangered groups of birds globally. Fledglings of burrow-nesting seabirds, and to a lesser extent adults, are attracted to and then grounded (i.e., forced to land) by lights when they fly at night. We reviewed the current state of knowledge of seabird attraction to light to identify information gaps and propose measur...
This research aims to design an IoT-based home light monitoring system using Wemos D1 Mini. tool is designed control the current and voltage contained in house lights automatically. The sensor used measure ACS712 sensor, ZMPT101B sensor. simulation of on this uses three LED lights, where each lamp located terrace house, living room, kitchen with different power variations. In addition, Blynk ap...
In this project, a new threshold signing scheme for RSA has been proposed. The scheme does not require a trusted third party and no secure information is leaked throughout the protocol. The time and storage complexity of the protocol is linear in the number of parties and no restriction is placed on the RSA moduli. Combined with the n-out-of-n key generation protocol of Boneh and Franklin, one ...
