The 20 revised full papers of the APPROX 2008 workshop were carefully reviewed and selected from 42 submissions and focus on algorithmic and complexity issues surrounding the development of efficient approximate solutions to computationally difficult problems. RANDOM 2008 is concerned with applications of randomness to computational and combinatorial problems and accounts for 27 revised full papers, also diligently reviewed and selected out of 52 workshop submissions.Theoretical Computer Science and General Issues,2512-2029 ;5171Computer programmingComputer scienceAlgorithmsComputer science—MathematicsDiscrete mathematicsNumerical analysisProgramming TechniquesTheory of ComputationAlgorithmsDiscrete Mathematics in Computer ScienceNumerical AnalysisComputer programming.Computer science.Algorithms.Computer science—Mathematics.Discrete mathematics.Numerical analysis.Programming Techniques.Theory of Computation.Algorithms.Discrete Mathematics in Computer Science.Numerical Analysis.004Goel AshishInternational Workshop on Randomization and Computation(12th :2008 :Boston, Mass.)MiAaPQMiAaPQMiAaPQBOOK996466075503316Approximation, Randomization, and Combinatorial Optimization.

Leclerc, Thomas Foken1st ed. 2014.Berlin, Heidelberg :Springer Berlin Heidelberg :Imprint: Springer,2014.1 online resource (254 p.)Description based upon print version of record.1-322-13903-2 3-642-54544-0 Includes bibliographical references and index at the end of each chapters.History and definition -- Surface layer properties and parameterizations -- Classification of footprint models -- Footprint studies -- Model validation -- Land surface – coupled footprints -- Application of footprint models to different measurement techniques -- Practical applications of footprint techniques -- Looking forward to the next generation of footprint models.How to interpret meteorological measurements made at a given level over a surface with regard to characteristic properties such as roughness, albedo, heat, moisture, carbon dioxide, and other gases is an old question which goes back to the very beginnings of modern micrometeorology. It is made even more challenging when it is unclear whether these measurements are only valid for this point/region and precisely describe the conditions there, or if they are also influenced by surrounding areas. After 50 years of field experiments, it has become both apparent and problematic that meteorological measurements are influenced from surfaces on the windward side. As such, extending these measurements for inhomogeneous experimental sites requires a quantitative understanding of these influences. When combined with atmospheric transport models similar to air pollution models, the ‘footprint’ concept – a fundamental approach introduced roughly 20 years ago – provides us with information on whether or not the condition of upwind site homogeneity is fulfilled. Since these first models, the development of more scientifically based versions, validation experiments and applications has advanced rapidly. The aim of this book is to provide an overview of these developments, to analyze present deficits, to describe applications and to advance this topic at the forefront of micrometeorological research.  .Atmospheric scienceClimatologyGeographyEcologyEnvironmental monitoringPhysical geographyAtmospheric ScienceClimate SciencesGeographyEcologyEnvironmental MonitoringEarth System SciencesAtmospheric science.Climatology.Geography.Ecology.Environmental monitoring.Physical geography.Atmospheric Science.Climate Sciences.Geography.Ecology.Environmental Monitoring.Earth System Sciences.333.7363.706355551.5Leclerc Monique Yauthttp://id.loc.gov/vocabulary/relators/aut1058768Foken Thomasauthttp://id.loc.gov/vocabulary/relators/autBOOK9910298379403321Footprints in Micrometeorology and Ecology2502399UNINA
