Solar radiation in external urban spaces
… to determine the distribution and intensity of solar radiation in urban spaces. New, tall buildings often reduce the quality of their immediate environment by intercepting sunlight before it reaches street level. While planners and the local authority recognise the necessity to rehumanise the …

Solar radiation control by pyrolytic oxide thin films
… films. A few of these new applications include solar collectors, solar reflectors, and thermal transparent insulation. The engineer must fully understand how oxide thin films optically behave and what mechanisms govern this behavior before utilizing them for these new applications. Only when …

Highly Physical Solar Radiation Pressure Modeling During Penumbra Transitions
Solar radiation pressure (SRP) is one of the major non-gravitational forces acting on spacecraft. Acceleration by radiation pressure depends on the radiation flux; on spacecraft shape, attitude, and mass; and on the optical properties of the spacecraft surfaces. Precise modeling of SRP is needed …

Machine Learning Approach to Forecast Global Solar Radiation Time Series
… supply into the grid by forecasting the Global Solar Radiation (GSR) on a localization where a Photovoltaic (PV) system is connected. This thesis tries to address the issue using Machine Learning (ML) techniques. This eases the generation scheduling task. The work developed on this thesis is …

Interactive microcomputer model for solar radiation evaluation and photovoltaic output comparison
The basic resource of all solar systems is the sun, and a knowledge of the quantity of the energy available is of prime importance. Although the solar radiation outside the atmosphere is known and almost constant, various climatic factors cause wide variations in its value on the earth's surface. …

Simulating high flux solar radiation and assessing its influence on a sooty flame
Integrating concentrated solar thermal energy into fossil-fuels for the production of power/clean fuels is receiving growing attention as the combination of the two energy sources can provide lower emissions of carbon and other pollutants, lower cost, and continuous supply. Various types of hybrid …

Stochastic Simulation of Hourly Rainfall, Total Cloud Cover, and Solar Radiation in Canadian Stations
… simulating the hourly variations of cloud cover, solar radiation, and rainfall at various Canadian stations. The calibration of these models was carried out individually for 279 rainfall stations, 132 total cloud cover stations, and 564 solar radiation stations, which are geographically dispersed …

Solar radiation pressure, drag and gravitational effects on a dust particle in Earth orbit
… perturbations on particle orbits is the solar radiation pressure (SRP), which is defined as the pressure exerted by the photons constituting the light from the Sun. Colombo et. al studied the orbital dynamics of ``smart-dust'' under the effects of SRP and atmospheric drag. The numerical …

Computationally Efficient Optimization of Formation Flying Trajectories, with Solar Radiation Pressure, near Lagrange Points
… starshade may be modeled under the influence of solar radiation pressure (SRP), which expands the domain of fuel-free trajectories it can exploit by treating SRP as a means of actuation rather than a perturbation to be corrected. Since the restricted three-body problem has no closed-form …

Stability of Beams, Plates and Membranes due to Subsonic Aerodynamic Flows and Solar Radiation Pressure
… membranes due to subsonic aerodynamic flows or solar radiation forces. Beams, plates and membranes are simple structures that may act as building blocks for more complex systems. In this dissertation we explore the stability of these simple structures so that one can predict instabilities in …

A Radiative Model for the Study of the Feedback Mechanism between Photolytic Aerosols and Solar Radiation
… study is to ascertain the sensitivity of the solar radiative field in the atmosphere to absorption and scattering by aerosols. This effort is preliminary to the study of feedback mechanisms between photolytic processes that create and destroy aerosols and the radiation field itself. In this …
