Identification of Information in Decision Systems
(2007)Extending unique identification to non-physical objects (data, information, decisions, knowledge) is a challenging problem in systems engineering. The tools and technologies available for naming physical objects may soon ... -
The impact of surface albedo on climate and building energy consumption: review and comparative analysis
(Transportation Review Board, 2015-08)This paper presents a state-of-the-art review of the existing research on the climate impacts of albedo. Different analytical approaches and modeling works are synthesized and discussed. -
The Implementation and Validation of Improved Landsurface Hydrology in an Atmospheric General Circulation Model
(Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrology and Water Resource Systems, Dept. of Civil Engineering, Massachusetts Institute of Technology, 1991-10)New landsurface hydrological parameterizations are implemented into the NASA Goddard Institute for Space Studies (GISS) General Circulation Model (GCM). These parameterizations are: 1) runoff and evapotranspiration functions ... -
Incorporation of Channel Losses in the Geomorphologic IUH
(Cambridge, Mass. : Ralph M. Parsons Laboratory, Hydrology and Water Resource Systems, Massachusetts Institute of Technology, Dept. of Civil Engineering, 1983-07)The infiltration losses along the streams of a basin are included into the Instantaneous Unit Hydrograph (IUH). The IUH is derived as a function of the basin geomorphologic and physiographic characteristics, and the response ... -
Infiltration and Evaporation at Inhomogeneous Land Surfaces
(Cambridge, Mass. : Report / Ralph M. Parson Laboratory, Hydrology and Water Resource Systems, Dept. of Civil Engineering, School of Engineering, Massachusetts Institute of Technology, 1982-06)The local response of the land surface to atmospheric forcing is determined by the surface parameters, the surface state, and the forcing. Because these factors are highly variable at length scales smaller than those of ... -
