The focal objective of this work is to calculate the energy consumption for constructing the EGS (Enhanced Geothermal Systems) wells, to examine the energy (heat and power) performance of such well systems, and to propose and evaluate several ways for improving that performance.
The focal objective of data hiding is to write the secret data into the host media (called cover media), i.e., image, video, audio, and text.
Two cameras form a stereo pair and are equipped with long-focal objectives to sample a limited portion of the scene at high spatial resolution, while the third one is equipped with a wide-angle objective and it is intended for surveying the whole scene at low-resolution.
Briefly, fluorescence imaging was carried out using a cooled fast 14-bit EMCCD camera (iXonEM+ DU-860, Andor Technology) equipped with 50 mm focal length objective.
For example, with a nominally 18-mm focal length objective lens, we measure an axial scan range of 1450 µm with a resolution of 75 µm.
With a nominally 3-mm focal length objective lens, we measure an axial scan range of 60 µm with a resolution of 3.8 µm.
Reflectance images were acquired with a Cascade CCD camera (type 512B; Photometrics, Tucson, AZ, USA) equipped with a lens pair of a 135-mm and a 50-mm focal length objective (NA 0.46, 2.7× magnification) using custom software written in Labview (National Instruments, Austin, TX, USA).
The focal conservation objectives are the preservation of biodiversity (species and habitats), outdoor recreation and restoration of environments.
The cameras are equipped with different focal lens objectives, allowing the system to acquire both geometric and colorimetric information of an architectural surface (monuments, frescoes…) at different scales over areas of tens of square meters.
Bubbles were observed through the chamber window at ×40 magnification by means of a Wild™ M10 stereomicroscope with a long focal-length objective.
The spectrometer consists of a 75 mm focal length collimating objective, a 1200 l/mm diffraction grating, and a 150 mm objective which focuses the light onto the CMOS detector (spL4096-140km, Basler).
