A Review of Termination Rules of an Inexact Primal-Dual Interior Point Method for Linear Programming Problems
(Investigación Operacional, 2018)
In this paper we apply the Inexact Newton theory on the perturbed KKT-conditions that are derived from the Karush-Kuhn-Tucker optimality conditions for the standard linear optimization problem. We discuss different ...
A Comprehensive Review on 2D and 3D Models of Vertical Ground Heat Exchangers
(Renewable and sustainable energy reviews, 2018)
The ground source heat pumps (GSHPs) have been extensively applied to commercial and residential buildings owing to their high-energy efficiencies and low running costs. The key component of the GSHP is a ground heat ...
Improving reliability and functional sustainability of groundwater handpumps by coating the rubber piston seals with diamond-like carbon
In many rural communities, handpumps are essential in order to provide access to safe drinking water from groundwater sources. The functional sustainability of handpumps is poor, however, and most maintenance issues in ...
