Based on thermodynamic modeling, the thermodynamic performance, including energy and exergy efficiencies, under variable work conditions, such as electric load factor, solar irradiance and installation ratio, of the solar PV panels and heat collector is investigated and analyzed.
One of the main problems affecting parallel robots in industry is the low workspace to installation-space ratio.
Using three strategies on the same system, including drive range extension, base translation and dynamic joint reconfiguration, it is possible to enhance significantly the workspace to installation-space ratio, allowing fine manipulation over a large workspace.
The pipe stiffness of RSHCCP could satisfy the requirements for the installation flexural stiffness ratio of semi-rigid pipe as the applied load was more than 70% of its ultimate load.
Current machine tools for micro manufacturing feature unfavorable ratios of installation space to work space as well as moving masses compared to the work piece mass.
The best choice in the given conditions is the high temperature refrigerant R123, which has high stability, is fireproof and non-explosive, and has the advantages of low pressure in installations and small compression ratios.
The differential survival of males was also evident in the operational sex ratio: it changed significantly toward a less male-biased ratio after pool installation.
Further along the line in 2010, the rate of installed capacity of wind power generators slowed down and thus the wind power installation and grid in-feed ratio appeared to increase but the capacity of wind power not able to in-feed to the grid was still enlarging.
The effect of parameters, such as the pile-to-pile spacing ratio and the installation order on pile group response has been investigated.
Moreover, the budget of the photovoltaic installation is included, as well as its corresponding financial ratios and payback periods.
