Third International Workshop on Energy Efficient Data Centers, E2DC 2014, held in Cambridge, UK, in June 2014. The 10 revised full papers presented were carefully selected from numerous submissions. They are organized in three topical sections named: energy optimization algorithms and models, the future role of data centres in Europe and energy efficiency metrics for data centres.Computer Communication Networks and Telecommunications,2945-9184 ;8945Database managementElectronic digital computersEvaluationComputer networksComputers and civilizationElectronic data processingManagementComputer simulationDatabase ManagementSystem Performance and EvaluationComputer Communication NetworksComputers and SocietyIT OperationsComputer ModellingDatabase management.Electronic digital computersEvaluation.Computer networks.Computers and civilization.Electronic data processingManagement.Computer simulation.Database Management.System Performance and Evaluation.Computer Communication Networks.Computers and Society.IT Operations.Computer Modelling.004.0286Klingert Sonjaedthttp://id.loc.gov/vocabulary/relators/edtChinnici Martaedthttp://id.loc.gov/vocabulary/relators/edtRey Porto Milagrosedthttp://id.loc.gov/vocabulary/relators/edtMiAaPQMiAaPQMiAaPQBOOK9910483547303321Energy Efficient Data Centers2829852UNINA03906nam 22006495 450 991050638270332120251204111431.09783030771393303077139310.1007/978-3-030-77139-3(CKB)5340000000068547(MiAaPQ)EBC6792502(Au-PeEL)EBL6792502(OCoLC)1280604499(PPN)25829681X(BIP)81990544(BIP)80071486(DE-He213)978-3-030-77139-3(EXLCZ)99534000000006854720211025d2021 u| 0engurcnu||||||||txtrdacontentcrdamediacrrdacarrierSharpening Mathematical Analysis Skills /by Alina Sîntămărian, Ovidiu Furdui1st ed. 2021.Cham :Springer International Publishing :Imprint: Springer,2021.1 online resource (543 pages)Problem Books in Mathematics,2197-85069783030771386 3030771385 Preface -- Notations -- Sequences of Real Numbers -- Series of Real Numbers -- Power Series -- Derivatives and Applications -- Partial Derivatives and Applications -- Implicit Functions -- Challenges, Gems, and Mathematical Beauties -- An Artistry of Quadratic Series. Two New Proofs of Sandham-Yeung Series -- Solutions -- References -- Index.This book gathers together a novel collection of problems in mathematical analysis that are challenging and worth studying. They cover most of the classical topics of a course in mathematical analysis, and include challenges presented with an increasing level of difficulty. Problems are designed to encourage creativity, and some of them were especially crafted to lead to open problems which might be of interest for students seeking motivation to get a start in research. The sets of problems are comprised in Part I. The exercises are arranged on topics, many of them being preceded by supporting theory. Content starts with limits, series of real numbers and power series, extending to derivatives and their applications, partial derivatives and implicit functions. Difficult problems have been structured in parts, helping the reader to find a solution. Challenges and open problems are scattered throughout the text, being an invitation to discover new original methodsfor proving known results and establishing new ones. The final two chapters offer ambitious readers splendid problems and two new proofs of a famous quadratic series involving harmonic numbers. In Part II, the reader will find solutions to the proposed exercises. Undergraduate students in mathematics, physics and engineering, seeking to strengthen their skills in analysis, will most benefit from this work, along with instructors involved in math contests, individuals who want to enrich and test their knowledge in analysis, and anyone willing to explore the standard topics of mathematical analysis in ways that aren’t commonly seen in regular textbooks. .Problem Books in Mathematics,2197-8506Mathematical analysisFunctions of real variablesSequences (Mathematics)AnalysisReal FunctionsSequences, Series, SummabilityMathematical analysis.Functions of real variables.Sequences (Mathematics).Analysis.Real Functions.Sequences, Series, Summability.515Sintamarian Alina1072426Furdui OvidiuMiAaPQMiAaPQMiAaPQBOOK9910506382703321Sharpening mathematical analysis skills2900985UNINA
