Profiling driven scenario detection and prediction for multimedia applications

by Stefan Valentin Gheorghita, Twan Basten, Henk Corporaal - In Proc. of the International Conference on Embedded Computer Systems: Architectures, Modeling, and Simulation (IC-SAMOS , 2006
"... Abstract — Modern multimedia applications usually have realtime constraints and they are implemented using heterogeneous multiprocessor systems-on-chip. Dimensioning a system requires accurate estimations of resources needed by the applications. Overestimation leads to over-dimensioning. For a good ..."

-of-the atmosphere (TOA) radiative forcing. This occurs via several pathways: (1) by absorbing the solar radiation reflected by the surface-atmosphere-cloud system, BC reduces the albedo of the planet; (2) soot deposited over snow and sea ice can decrease the surface albedo 29, 30, 31, 32 ; (3) soot inside cloud

Surface air temperature and its changes over the past 150 years

by P. D. Jones, M. New, D. E. Parker, S. Martin, I. G. Rigor - Rev. Geophys , 1999
"... Abstract. We review the surface air temperature record of the past 150 years, considering the homogene-ity of the basic data and the standard errors of estima-tion of the average hemispheric and global estimates. We present global fields of surface temperature change over the two 20-year periods of ..."

Atmospheric budget of acetone

by Daniel J. Jacob, Brendan D. Field, Emily M. Jin, Isabelle Bey, Qinbin Li, Jennifer A. Logan, Robert M. Yantosca, Hanwant B. Singh - J. Geophys. Res , 2002
"... [1] The atmospheric budget and distribution of acetone are investigated by using a priori estimates of sources and sinks to constrain a global three-dimensional atmospheric model simulation and then using atmospheric observations from 14 surface sites and 5 aircraft missions to improve these estimat ..."

A Neoclassical Perspective on Budget Deficits

by B. Douglas Bernheim, Distinguished Professor, Risk Management - Journal of Economic Perspectives , 1989
"... I n the 1988 presidential campaign, virtually every serious candidate spoke of theurgent need to trim government budget deficits. Public opinion polls haveidentified federal deficits as a key economic issue, second only to unemployment.' While many economists are relieved by what they perceive ..."

farsighted individuals planning consump-tion over their own life cycles. Budget deficits raise total lifetime consumption by shifting taxes to subsequent generations. If economic resources are fully employed, increased consumption necessarily implies decreased saving. Interest rates must then rise to bring

Estimates of the global water budget and its annual cycle using observational and model data

by Kevin E. Trenberth, Lesley Smith, Taotao Qian, Aiguo Dai, John Fasullo - J. Hydrometeorol. 2007
"... A brief review is given of research in the Climate Analysis Section at NCAR on the water cycle. Results are used to provide a new estimate of the global hydrological cycle for long-term annual means that includes estimates of the main reservoirs of water as well as the flows of water among them. For ..."
Abstract - Cited by 43 (7 self) - Add to MetaCart
. For precipitation P over land a comparison among three datasets enables uncertainties to be estimated. In addition, results are presented for the mean annual cycle of the atmospheric hydrological cycle based on 1979–2000 data. These include monthly estimates of P, evapotranspiration E, atmospheric moisture

The carbon balance of tropical, temperate and boreal forests.

by Y Malhi , D D Baldocchi , P G Jarvis , Rd6 - Plant Cell and Environment, , 1999
"... ABSTRACT Forest biomes are major reserves for terrestrial carbon, and major components of global primary productivity. The carbon balance of forests is determined by a number of component processes of carbon acquisition and carbon loss, and a small shift in the magnitude of these processes would ha ..."

Simplified annual carbon balance diagrams (see The main difference between the three C budgets is that G p , and hence N p and the general magnitude of the carbon cycle, show a decreasing trend from the tropical site

Meridional structure and transports of energy in the atmosphere, ocean, and land are evaluated holistically for the mean and annual cycle zonal averages over the ocean, land, and global domains, with discussion and assessment of uncertainty. At the top of the atmosphere (TOA), adjusted radiances fro ..."

The annual cycle of the energy budget: Global mean and land-ocean exchanges

by John T Fasullo , Kevin E Trenberth
"... Abstract The mean and annual cycle of energy flowing into the climate system and its storage, release, and transport in the atmosphere, ocean, and land surface are estimated with recent observations. An emphasis is placed on establishing internally consistent quantitative estimates with discussion ..."
