Abstract |
It is the purpose of this bulletin to make available information concerning street illumination. The suggestion which led to this compilation came from the many inquiries received by the Electrical Engineering Department each year from those interested in framing ordinances permitting corporations or individuals to operate street lighting systems. An attempt has been made to present this information in such a form as to be readily understood by the general public, without requiring any special technical knowledge. The data have been compiled from reliable sources, and checked in many instances by tests conducted by the writers. |

Abstract |
Temperature, humidity and moisture content are the important abiotic component regulating seedling establishment in plants including rice. Light factor intensity and duration are also important environmental factors regulating rice growth and development. In the growth and development of rice crop germination followed by seedling establishment is the foremost and very important growth stages. Light component such as intensity, direction and duration are the regulating factor for several physiological, biochemical and molecular processes in plants. To consider these facts, in the present piece of work rice seed of HUR-105 grown under different light regimes, from T1 (2000 lux for 12 h during day time + 12 h dark period) (lower light intensity), T2 (4000 lux for 12 h during day time+ 12 h dark period), T3 (6000 lux for 12 h during day time + 12 h dark period) (moderate), T4 (9000 lux for 12 h during day time + 12 h dark period) (optimum) and to T5 (9000 lux for 12h during day time + 200 lux for 12 h during night time). Germination, seedling growth and biochemical parameters were observed at different time intervals. It was observed that germination %, germination index (GI), germination rate index (GRI), coefficient of velocity of germination (CVG), mean germination rate (MGR), seedling vigour (SV), α-amylase activity and soluble sugar content significantly reduced in both the treatments T1 and T5. Further, the mean time germination and insoluble sugar content were increased in T1 and T5 treatment. The present experiment concluded that both lower light intensity (T1) and addition of low light during dark period (considered as night light pollution) causes stress condition and reduce germination and seedling establishment potential of rice crop. |

Abstract |
Об’єктом дослідження є процес сталого розвитку територіальних одиниць на прикладі регіонів України. Концепція сталого розвитку стала провідною стратегією розвитку для більшості країн світу. Однією із найбільших проблем залишається отримання повних та верифікованих даних для моделей оцінювання розвитку. В роботі було використано методику розрахунку індексу сталого розвитку, яка розроблена в Світовому центрі даних з геоінформатики та сталого розвитку Національного технічного університету України «Київський політехнічний інститут ім. Ігоря Сікорського». Дана методика ґрунтується на розрахунку метрики індексу сталого розвитку на основі вимірів якості життя населення та безпекової компоненти проживання для окремих країн та регіонів. Для застосування методики на регіональному рівні було запропоновано використання інформації про нічне освітлення території, яка отримується засобами дистанційного зондування Землі із супутникових систем. Досліджено характер та тісноту зв’язку між яскравістю нічного освітлення та індикаторами сталого розвитку. З’ясовано, що найбільш значущий зв’язок наявний між показниками індексу економічного розвитку, індексом впливу на зміну клімату та нічним освітленням території регіонів України. На основі геоінформаційного аналізу програмного забезпечення ArcGIS компанії ESRI було застосовано інструментарій статистичного зонування, який надає можливості для статистичної обробки даних супутникових знімків у межах виокремлених за адміністративним принципом регіонів або інших полігональних областей. На основі математичного апарату інтелектуального аналізу даних було здійснено глобальний та локальний регресійний аналіз зв’язку між виявленими показниками. Розгляд тісноти цього зв’язку в територіальному розрізі дозволив виявити зони з найбільшою та низькою тіснотою впливу, що пояснюється особливостями соціально-економічного розвитку даних територій. Завдяки цьому забезпечується можливість отримання розрахунку аналогічних показників на більш детальних територіальних рівнях, які відповідають окремим районам або містам обласного значення |

Abstract |
CUMULOS is a three-camera system flying as a secondary payload on the Integrated Solar Array and Reflectarray Antenna (ISARA) mission with the goals of researching the use of uncooled commercial infrared cameras for Earth
remote sensing and demonstrating unique nighttime remote sensing capabilities. Three separate cameras comprise the CUMULOS payload: 1) a visible (VIS) Si CMOS camera, 2) a shortwave infrared (SWIR) InGaAs camera, and 3) a longwave infrared (LWIR) vanadium oxide microbolometer. This paper reviews on-orbit operations during the past year, in-space calibration observations and techniques, and Earth remote sensing highlights from the first year of space
operations. CUMULOS operations commenced on 8 June 2018 following the successful completion of the primary ISARA mission. Some of the unique contributions from the CUMULOS payloads include: 1) demonstrating the use of bright stars for on-orbit radiometric calibration of CubeSat payloads, 2) acquisition of science-quality nighttime lights data at 130-m resolution, and 3) operating the first simple Earth observing infrared payloads successfully flown on a CubeSat. Sample remote sensing results include images of: cities at night, ship lights (including fishing vessels), oil industry gas flares, serious wildfires, volcanic activity, and daytime and nighttime clouds. The CUMULOS VIS camera has measured calibrated nightlights imagery of major cities such as Los Angeles, Singapore, Shanghai, Tokyo, Kuwait City, Abu Dhabi, Jeddah, Istanbul, and London at more than 5x the resolution of VIIRS. The utility of these data for measuring light pollution, and mapping urban growth and infrastructure development at higher resolution than
VIIRS is being studied, with an emphasis placed on Los Angeles. The “Carr”, “Camp” and “Woolsey” fires from the 2018 California fire season were imaged with all three cameras and results highlight the excellent wildfire imaging
performance that can be achieved by small sensors. The SWIR camera has exhibited extreme sensitivity to flare and fire hotspots, and was even capable of detecting airglow-illuminated nighttime cloud structures by taking advantage of the strong OH emissions within its 0.9-1.7 micron bandpass. The LWIR microbolometer has proven successful at providing cloud context imagery for our nightlights mapping experiments, can detect very large fires and the brightest flare hotspots, and can also image terrain temperature variation and urban heat islands at 300-m resolution. CUMULOS capabilities show the potential of CubeSats and small sensors to perform several VIIRS-like nighttime mission areas in which wide area coverage can be traded for greater resolution over a smaller field of view. The sensor
has been used in collaboration with VIIRS researchers to explore these mission areas and side-by-side results will be presented illustrating the capabilities as well as the limitations of small aperture LEO CubeSat systems. |
