Best power exists when the distance between the Fresnel lenses and the CPC equal to the focal length, unlike when the focal length is less than the distance (Partain & Fraas 318). The phenomenon occurs because of loss in the concentrated beam that falls on the CPC. Besides, focal point forms at CPC if focal length is longer than the distance. Therefore, change in the path of the incident beam results into loss of the beam (Fraden 164). First law of refraction highlights the if the distance between the Fresnel lenses and the CPC equal to the focal length, most of the beam will concentrated at exit aperture (Lindenfeld and Brahmia 241)
Moreover, the experiment established acceptance angle. Adjusting the Angle of incidence beam on the Fresnel lens (Tilt About x), when the distance between the Fresnel lenses and the CPC equal to the focal length as showing below.
Based on the experiment, we identified that power generated by the CPV system decrease with increase in the Incidence angle (Luque 89). Whereas, at a point where power equal to zero, the Incidence angle becomes the Acceptance angle, usually (4o). Hence, the system limits deviation of radiation falling more than three degrees (Fischer 140). As shown in Table
6.9). Correspondingly, the material (PMMA), radial height (0.846 mm), and thickens (4mm) are added to the Fresnel 1 row (Illuminating Engineering Society 104), (Fig…
Imaging with the help of Magnetic Resonance Imaging, Computerized Tomography, Positron Emission Tomography and similar ones-has become very much popular and is in wide spread use-even in developing countries. The evolution of these techniques has been the outcome of the various drawbacks associated with older techniques like Nasal Radium Irradiation and others-which have had their effects-often irreversible, on the people on which they were used.
In fact, R&D has made possible for it to get higher performance to follow with its low cost and ease of installation (The FOA, 2008; Paschotta, 2014). This report presents a detailed analysis of plastic optical fiber. This report will discuss basic
Data in the optical fibre is transmitted inside the core which allows light transmission. The core makes up about 96% of the diameter of the entire fibre. Compared to the glass fibre, the core of plastic optic fibre
The first could be from exposure to the sun responsible for cosmic radiation as a result of solar flares. I could also be exposed to radon gas from enclosed environments such as home known to emit the radioactive alpha
The moisture supply reduces stability of the atmosphere that establishes favorable environment for organizes conventions that act as a precondition to tropical cyclones.
August through November is the time that the hurricanes activity
This research has been conducted with the aim of unmasking the potential that the solar energy possess if it was fully exploited. In this case, various aspects relating to solar energy harnessing have been highlighted to enlighten readers on how to install their own solar panels to tap this environmental friendly energy source.
The author states that solar energy has many advantages in Hong Kong since there is abundant sunlight. High-rise and high-density urban environment often create difficulties for energy applications. There have been interesting results derived from using solar systems. Wind and solar energy have been proposed to be used in the "Hong Kong Disneyland”.
