Measurement of Environmental Physical Parameters
2003Any artefact is influenced by the surrounding environment, in terms of stress produced by physical factors such as temperature, light irradiation and humidity, and, in a more general sense, by the microclimate resulting from the synergy of all these factors (Stainer et al, 1984; Fea, 1988; Monteith, 1990; Camuffo et al., 2001).

Environmental parameters in museums
Building and Environment, 2003During the last decade, the environmental conditions of the museum exhibition facilities and storage areas have been shown to be the most crucial factor, concerning the preservation of collections and artifacts. The pollution (chemicals and noise), the humidity, the temperature and the lighting can possibly deteriorate or even destroy the material ...

Remote sensing of environmental parameters
The Journal of the Acoustical Society of America, 1982This paper describes a prototype environmental parameter sampling system and the problems it is intended to address. Increasingly sophisticated sonar performance models are being developed in support of advanced sonar system. A graphic portrayal of the simulated performance of a notional sonar system is presented as an example of the sensitivity of a ...

Environmental parameters in building design
Building and Environment, 1988Abstract A comfortable thermo-visual environment indoors is a prerequisite for a good office design. Various design approaches in isolation either do not lay due emphasis on the overall quality of indoor environment or are not economically energy efficient.

Environmental Parameter Monitoring Using Wireless Sensor Network
Приборы и техника эксперимента, 2013The paper presents the design and deployment of Wireless Sensor Network (WSN) for monitoring environmental parameters. The system measures air temperature, relative humidity, solar radiation and barometric pressure. The system consists of a base station and a wireless sensor node. WSN ethernet gateway attached to a host PC serves as the base station in

Relationships between skin properties and environmental parameters
Skin Research and Technology, 2007Background/purpose: Many authors have written about skin physiological parameters and their changes according to different environmental conditions. Nevertheless, the literature puts in evidence disagreement among different studies due to the great variability in these parameters and due to the difficulty in comparing the results obtained under ...

Environmentally specific mechanical properties: Beyond atomic parameters
Physical Review B, 1988Representative wave functions of Cu, ${\mathrm{Ir}}_{3}$Cr, and ${\mathrm{Zr}}_{3}$Al as determined from multiple-scattering $X\ensuremath{\alpha}$ cluster calculations are compared. While atomic parameters, specifically $s$-orbital electronegativities, predict an isotropic charge density for ${\mathrm{Ir}}_{3}$Cr and an anisotropic charge density for $

Estimating return values of environmental parameters
Quarterly Journal of the Royal Meteorological Society, 1981AbstractReturn values of an environmental parameter, such as wind speed or wave height, are frequently estimated from an extreme value analysis of observed annual maxima assuming that the parameter is identically distributed throughout the year. Environmental data generally have considerable within‐year variation.

Environmental and Hazard Parameters
2011This section describes the foundational information collected for identifying typical/standard fire and smoke scenarios, likely false/nuisance scenarios, and a range of ambient conditions to which VID systems may be subjected in the three target applications.

Environmental Parameter Control of the Greenhouse
2013 Fifth International Conference on Measuring Technology and Mechatronics Automation, 2013Aiming at the high-precision mechanism model of the greenhouse and the problem of the nonlinear strong coupling between temperature and humidity, this paper employs the method of accurate linearization in the nonlinear system. The exact linearization of the system is realized through state feedback", "and then realizes the gradual tracking of the ideal
