Abstract: The hydraulic ram pump was invented over 200 years ago but became obsolete with the availability of mains water. Ram pumps make use of a renewable energy resource and are environmentally ...

Abstract: A model, incorporating Darcy's law, is developed for single‐species gas flow inside a nonisotropic porous medium, within which gas is continuously generated. A linear parabolic equation is derived to express the internal ...

Abstract: This paper presents a series of tests on cold-formed steel plain (unstiffened) angle columns compressed between fixed ends. The test specimens were brake-pressed from high strength structural steel sheets. Tests were ...

Abstract: Data, collected correctly and analyzed systematically, provide a solid basis for understanding the traffic system. This paper discusses recent developments in the collection and analysis of video data. It is particularly ...

Abstract: A method of designing least‐cost branched‐water‐supply networks for rural communities on uneven terrain is described. Previous studies have been concerned with networks on relatively flat terrain and have not taken account ...

Abstract: An experimental investigation of cold-formed steel lipped angle concentrically loaded compression members is presented in this paper. The angle specimens were tested between fixed-ended conditions at various column lengths. ...

Abstract: This study investigates annual performance of the hybrid energy system with geothermal and solar heat sources for hot water, heating and cooling of a residential house in South Korea. A smallscale hybridrenewable energy ...
