Abstract:

The disruption to natural light regimes caused by outdoor artificial nighttime lighting has significant impacts on human health and the natural world. Artificial light at night takes two forms, light emissions and skyglow (caused by the scattering of light by water, dust and gas molecules in the atmosphere). Key to determining where the biological impacts from each form are likely to be experienced is understanding their spatial occurrence, and how this varies with other landscape factors. To examine this, we used data from the Visible Infrared Imaging Radiometer Suite (VIIRS) day/night band and the World Atlas of Artificial Night Sky Brightness, to determine covariation in (a) light emissions, and (b) skyglow, with human population density, landcover, protected areas and roads in Britain. We demonstrate that, although artificial light at night increases with human density, the amount of light per person decreases with increasing urbanization (with per capita median direct emissions three times greater in rural than urban populations, and per capita median skyglow eleven times greater). There was significant variation in artificial light at night within different landcover types, emphasizing that light pollution is not a solely urban issue. Further, half of English National Parks have higher levels of skyglow than light emissions, indicating their failure to buffer biodiversity from pressures that artificial lighting poses. The higher per capita emissions in rural than urban areas provide different challenges and opportunities for mitigating the negative human health and environmental impacts of light pollution.

Abstract:

Red-light Running increases the risk of collisions and traffic accidents. When a car runs a red light, it can cause a collision with other vehicles moving along the main road, causing serious accidents and even leading to casualties. In Vietnam, many traffic accidents are caused by red-light running. This research paper presents a novel approach for detecting red-light running violations for Vietnamese intersections by leveraging object detection techniques and the YOLO (You Only Look Once) algorithm, a deep neural learning model that uses convolutional neural network architecture (CNNs) for object detection in real-time. The proposed system utilizes CCTV video footage to capture video frames, which are then processed through a trained YOLOv8 model to identify red-light violators. The system's performance is evaluated based on detection accuracy and processing speed and validated against a custom build dataset extracted from CCTV footages of Vietnamese streets. The experimental results demonstrate high accuracy and processing efficiency up to 93.4% mAP50, 89.2% precision and 92.6% recall, indicating that the proposed approach is suitable for deployment in the context of Vietnamese traffic conditions. The proposed system has significant potential to enhance road safety and mitigate the incidence of red-light running violations in Vietnam.

Abstract:

OBJECTIVETo assess beliefs about the tar and nicotine delivery characteristics and health benefits of Light and Ultra Light cigarettes among cigarette smokers.DESIGNRandom digit dialed telephone survey conducted in September 1999.SUBJECTSDaily smokers (n = 2120) of Regular (46%), Light (39%), and Ultra Light (15%) cigarettes in the USA. The sample was weighted to match the US smoker population on age, sex, and ethnicity.MAIN OUTCOME MEASURESBeliefs about Light and Ultra Light cigarettes were summarised on three dimensions: Safety (reduced health risk), Delivery (lowered tar and nicotine delivery), and Sensation (less harsh).RESULTSMost smokers believed Lights and Ultra Lights were less harsh and delivered less tar and nicotine. On average, smokers believed that Lights afforded a 25% reduction in risk, and Ultra Lights a 33% reduction in risk. Light and Ultra Light cigarette smokers evaluated the risks of their own cigarette types more favourably. Light smokers had greater interest in quitting than Ultra Light smokers. Quitting intention was modestly related to beliefs about these cigarettes. Believing that Lights and Ultra Lights delivered less tar and nicotine and that they were less harsh each independently contributed to the belief that these cigarettes were safer.CONCLUSIONSMany Light and Ultra Light smokers believe that smoking these cigarettes impart a substantial health benefit, due in part to their experience that these cigarettes are less harsh and the belief that these cigarettes deliver less tar.

Abstract:

The goal of Red Light Violation Detection System RLVDS is to track down vehicles that violated traffic regulations using surveillance cameras and image processing techniques. A complete automated red light runner detection algorithm that satisfies real time requirement and gives higher accuracy have been developed. The system detects simultaneously a traffic light sequence, stop line and detection region to detect moving vehicles and capture the vehicles beyond the stop line while the light is red and finally generates the red light running vehicle images with date and time information. In this paper, we propose a traffic light detection algorithm which is one of the processes of automated red light runner detection system. The proposed traffic light detection system includes four steps color space conversion based on RGB color space, some regions are extracted as candidates of a traffic light and morphological operation is applied to eliminate disturbance in the environment that can interfere with the traffic light states. Then, the types of traffic signals are judged by calculating image moments and the results of experiment show that the system is stable and reliable.

Abstract:

ABSTRACT Traffic lights are signaling devices positioned at road intersections, pedestrian crossings, and other locations to control flows of traffic. An actual traffic light alternates the right way of road users by displaying lights of a standard color (red, yellow/amber, and green), using a universal color code (and a precise sequence to enable comprehension by those who are color blind). In the typical sequence of colored light, (1) illumination of the green light allows traffic to proceed in the direction denoted; (2) illumination of the yellow/amber light denoting ready to proceed in the direction denoted; and (3) illumination of the red signal prohibits any traffic from proceeding. Usually, the red light contains some orange in its hue, and the green light contains some blue, for the benefit of people with red-green color blindness, and green lights in many areas are in fact blue lenses on a yellow light (which together appear green). Program was written for the MDE trainer kit to control the outputs of the microcontroller in a given sequence. Green and red light-emitting diodes (LEDs) are connected to the microcontroller outputs. First, the assembly language programs were written to turn on only one LED and then turn off the same LED. Next, the program is improved by making the LED blink, and then, the input switches are read. The walk push button and the other indicating a car at the crossing light are turned on. As switches are mechanical objects, some debounce time (timer programmed dead time of 50 ms) is also placed in the program. The light is controlled as long as each LED with one switch is pressed, and the LED is ON and when the switch is not depressed, the LED is OFF. Then, the LED will be made to blink once per second as long as the associated switch is ON. Finally, the program is improved when a subroutine is added where the traffic light controller is on green or red stays ON while the corresponding switch is ON. If more than one switch is activated, then the ON is for the red light. The LEDs simulate the traffic lights and switches simulate the walk push button and the car presence sensor at a crossroad.

Abstract:

Abstract Despite Jürgen Habermas’ famous suggestion that the violence of history might be mitigated by “the liquidation of unconditional claims,” the issue of whether monotheistic religions and the metaphysical rationality they engender are indeed the hidden source of such violence remains an open one. This essay explores how Derrida with his project “deconstruction” sought to deal in a manner unique to philosophy with the question of the relationship between violence, the unconditional, and the ontological. It proposes that Derrida’s “Jew-Greek” dilemma, which encapsulates the problem of the “violence” of metaphysics, is resolved through Levinas’ project of disrupting Husserlian phenomenology with an alterity that is not simply a heteron that disintermediates the logic of predication, but one that challenges what is normally meant by philosophy itself.

Abstract:

Emerging lighting technologies provide opportunities for reducing carbon footprints, and for biodiversity conservation. In addition to installing light-emitting diode street lights, many local authorities are also dimming street lights. This might benefit light-averse bat species by creating dark refuges for these bats to forage and commute in human-dominated habitats. We conducted a field experiment to determine how light intensity affects the activity of the light-opportunistic Pipistrellus pipistrellus and light-averse bats in the genus Myotis. We used four lighting levels controlled under a central management system at existing street lights in a suburban environment (0, 25, 50 and 100% of the original output). Higher light intensities (50 and 100% of original output) increased the activity of light-opportunistic species but reduced the activity of light-averse bats. Compared to the unlit treatment, the 25% lighting level did not significantly affect either P. pipistrellus or Myotis spp. Our results suggest that it is possible to achieve a light intensity that provides both economic and ecological benefits by providing sufficient light for human requirements while not deterring light-averse bats.

Abstract:

Contemporary models of light conditions on the forest floor can be divided into two categories: undercanopy models that allow the light conditions in a stand under the canopy to be simulated, and models that take into account shielding from the side. Under-canopy models precisely estimate the availability of wavelengths of light spatially distributed under the canopy of stands: however, these models require a large amount of data on the spatial structure of forest stands. The other class of models describe the light conditions on a particular open surface. These incorporate shielding from the side and are easier to use as they require less data than under-canopy models. In practice, in forest conditions, such models require data on the size, shape and geographical location of surveyed surfaces (e.g. gaps and cut areas) and on the height of the surrounding stand. Often, these data are available in databases, such as the State Forest Information System (SKP), orcan otherwise be obtained relatively easily (and inexpensively). Compared to under-canopy models, these models provide a cheap way to obtain useful information on variation in the light environment that affects the microclimate for regenerating plants on clearcuts and canopy gaps.

Abstract:

AbstractWe have mapped quantitative trait loci (QTL) responsible for natural variation in light and hormone response between the Cape Verde Islands (Cvi) and Landsberg erecta (Ler) accessions of Arabidopsis thaliana using recombinant inbred lines (RILs). Hypocotyl length was measured in four light environments: white, blue, red, and far-red light and in the dark. In addition, white light plus gibberellin (GA) and dark plus the brassinosteroid biosynthesis inhibitor brassinazole (BRZ) were used to detect hormone effects. Twelve QTL were identified that map to loci not previously known to affect light response, as well as loci where candidate genes have been identified from known mutations. Some QTL act in all environments while others show genotype-by-environment interaction. A global threshold was established to identify a significant epistatic interaction between two loci that have few main effects of their own. LIGHT1, a major QTL, has been confirmed in a near isogenic line (NIL) and maps to a new locus with effects in all light environments. The erecta mutation can explain the effect of the HYP2 QTL in the blue, BRZ, and dark environments, but not in far-red. LIGHT2, also confirmed in an NIL, has effects in white and red light and shows interaction with GA. The phenotype and map position of LIGHT2 suggest the photoreceptor PHYB as a candidate gene. Natural variation in light and hormone response thus defines both new genes and known genes that control light response in wild accessions.

Abstract:

Currently, there is a demand for more energy-efficient lighting sources, however, light emitted by different lighting systems differs in primary properties such as intensity, propagation direction, and wavelength spectrum, among others, and these properties may affect insect light attraction. Despite the energetic benefits of light-emitting diodes (LED) as street light systems, their ecological impacts on insects have not yet been tested on a wide range of taxa. Using an experimental approach, we showed that LED street lights lead to a reduction in the total number of insects captured with light traps in a wide range of families. Coleoptera and Lepidoptera orders were the most sensitive groups to ecological light pollution in the study area. We suggest that LED was the least attractive light system for most of the affected groups both because of its very little emitted short-wavelength light and because of its lower light intensity. We expect that the more and more widespread use of LED lights as a measure to reduce economic costs of outdoor lighting should lead to a lower attraction to street lights in most of the affected insect taxa and to diminish the negative impacts of artificial light attraction on the ecosystems.

Abstract:

Automatic lights with light sensors are lights that can turn on and off automatically without using a switch. The light sensor in automatic lights works by converting light quantities into electrical quantities. The working principle is that when the sensor detects the presence of light, the light will turn off, and vice versa. Here are some of the benefits of using automatic lights with light sensors: Save energy and reduce electricity bills, Increase comfort, Reduce the need to adjust lighting manually, Save labor and time. Light sensors work by utilizing the principles of electric current and resistance. When light hits the sensor, the resistance will increase or decrease according to its position, thereby regulating the current

Abstract:

Abstract: Automatic Street light systems require less maintenance than traditional street lights because they do not have any moving parts. Because the autonomous street light system is self-contained, it does not require any external wiring or grid connection. When the sunlight falls below the visible region of our eyes, the lights in this Street Light Control System will automatically turn on, and when the sunshine returns, the lights will immediately turn off.There is no requirement for manual operation in this project, such as setting the ON and OFF times. This system uses a motion detection sensor which helps to automatically increase the intensity of the street light when a car or pedestrian is noticed in the area. If there is no activity in the area, the light is automatically changed to a minimum light level that is optimum.

Abstract:

Monochromatic light and wide-band white light both affect plant growth and development. However, the different effects between monochromatic light and addition white light to monochromatic light on the formation, growth, and dormancy of microtubers have not been fully explored. Therefore, we evaluated these effects using in vitro potatoes grown under pure blue and red lights and a combination of blue light and red light supplemented with white light, respectively. Current results suggested that light spectra influenced microtuber formation, growth, and dormancy by regulating potato plantlet morphogenesis, affecting the synthesis and transportation of photosynthetic metabolites, and altering the accumulation and distribution of biomass in various plant tissues. Monochromatic lights and the combined spectra had differing effects. For instance, monochromatic red light induced the growth of more microtubers, whereas addition white light to red light decreased number but increased weight of microtubers. Meanwhile, monochromatic blue light facilitated tuber growth, whereas addition white light to blue light decreased microtubers weight but increased microtuber number. In addition, composite lights of addition white light to monochromatic red and blue lights both extended the dormancy period, and monochromatic blue light shortened the dormancy period of microtubers >300 mg. Therefore, in microtuber agricultural production, specific light conditions may be applied at different growth stages of in vitro potatoes to increase the number of effective microtubers (>50 mg) and to satisfy storing requirement of seed microtubers.

Abstract:

The purpose of this research is to analyze the relationship between the intensity of light hitting the LDR to the resistance and the flame of the light. The research created an automatic lighting system, in which the lighting system was designed to turn on or off lights by light intensity. This research created automatic light controls using LDR light sensor. The LDR light sensor set is used as a switch that turns on or off a light automatically based on the recieved of intensity of light. By using the LDR components, it can design a series of light sensors for such items as outdoor light sensors, sleeping lights, garden lights, road lights that turn on at night and go out during the day automatically. The equipment used of the research were 2 test lamps, and done with 2 lighting sources, a natural source of lighting and an artificial source of lighting. From the research, it showed that the large light intensity affects the light flame by using LDR light sensor. It could be concluded that the greater of the light hitting intensity from the LDR surface was smaller than the value of the resistance and the flickering of the light. In contrast, the less light that affects the LDR, was the greater value of LDR resistance and lighter the light.

Abstract:

Nowadays, the use of halogen or light emission diode (LED) devices in dental attention is constant for almost any oral treatment. The need of providing an adequate light intensity for a correct photopolymerization of the resinous materials is critical. Likewise, it is important to consider the biosecurity norms for avoiding cross-contamination by residues likely to be accumulated at the top of the light guide in contact with oral cavity fluids. Therefore, the use of translucid barriers at the top of the light guide is imperative to protect the health of the patient while providing a correct polymerization of the resinous materials. The present study analyzes the effect of using four translucid barriers in the light intensity of three dental lamps commercially available. The tested barriers are two of commercial availability, and two conventional plastic wraps. Results indicate a significant reduction of light intensity without affecting the requirements for a correct photopolymerization with any barrier. Differences among barriers points out a conventional plastic wrap as more suitable than commercially available barriers, considering only light intensity provided.

Abstract:

A stationary lift net requires an effective fishing light attractor. The intensity and distribution of light are important factors to increase the effectiveness of fishing light attractors. This study aimed to probe the distribution of light intensity and its effect on the effectiveness of fishing light attractors. This research employed a descriptive-comparative method by comparing the effectiveness of LED lights with kerosene lights. The results showed that the concentration of fish school in LED lights was at a depth of 4–10 m with a light intensity of 1x10-8– 10x10-8 W/cm2, while the kerosene lights was deeper than LED lights at a depth of 8–12 meters with a light intensity of 1x10-8– 10x10-8 W/cm2. The distribution of fish schools from LED lights tends to be concentrated and form larger schools than kerosene lights. The optimum light intensity of LED and kerosene lights was almost the same, in the range of 1x10-8– 10x10-8 W/cm2, with concentrations of fish schools reaching 65% and 64%, respectively. The total catch of LED lights fish during eight fishing trips was 168.5 kg or an average of 21.06±2.32 kg/trip, while the total catch of kerosene lights was 139.6 or an average of 17.5±1.98 kg/trip.

Abstract:

Background: Retinal damage caused by blue light can result in glare, decreased visual acuity, and accelerated macular degeneration. In clinical practice, blue light-blocking glasses, such as driving glasses, are used to block blue light effectively. This study was aimed at measuring light transmittance to analyze the blue light-blocking efficiencies of blue light-blocking and driving spectacle lenses manufactured with tinting, coating, and only materials and at distinguishing the difference between the two spectacle lenses.  Methods: Blue light-blocking and driving spectacle lenses used to measure light transmittance were manufactured with tinting (blue light blocking lenses by tinting or “BTL” and driving spectacle lenses by tinting or “DTL,” respectively), coating (blue light blocking lenses by coating or “BCL” and driving spectacle lenses by coating or “DCL,” respectively), and only materials (blue light blocking lenses by material or “BML” and driving spectacle lenses by material or “DML,” respectively).  Results: Compared to BTL, DTL had a significantly greater decrease in the light transmission efficiency for visible and blue lights (P < 0.05). The blue light hazard function was lower for BML and DML than for conventional coating lenses in both visible and blue lights, although without significant differences between visible and blue lights (P > 0.05).  Conclusions: The blue light-blocking spectacle lenses had the highest blue light-blocking efficiency when manufactured with tinting, coating, and only materials, in order. With DML, the blue light-blocking efficiency was lower compared to DTL but higher compared to DCL. Therefore, DML could provide a balanced glare control and clear retinal image overall.
