This book contains nine peer-reviewed articles on green coal mining that address most of the important issues associated with improving coal mining. These issues include the protection of water above coal mines, both surface and ground water, and the subsidence that occurs during and after mining with methods to limit it and methods of rehabilitation. Additional issues include mine entry and production area support and methods to control gas emissions.History of engineering & technologybicsscdecision makingmanagementminesmulti-criteria analysisprojectriskrestorationcoal ganguegeopolymermechanical activationthermal activationmechanical propertymicrostructurewater protectionwater-conservation coal mining (WCCM)influencing factors“five mapsthree zonesand two zoning plans”water conductive fractured zone (WCFZ)acoustic emission (AE)coaldeep miningmining layoutslignitereclamationrehabilitationland usedecision-makingoptimisationsustainabilitylongwall coal miningground controlsubsidenceupliftsurface movementradar-interferometrylong-term behaviorsustainable miningBelgiumfoamed concreteorthogonal experimentoptimum mixcoal mine goafgas isolationlongwall miningweak geological conditiongate-entry stabilityremaining coal thicknesswooden cribsgangueload-displacement characteristicspressure-compressibility characteristicsHistory of engineering & technologySpearing A.J.Sedt1291778Spearing A.J.SothBOOK9910557284003321Green Coal Mining Techniques 20203021911UNINA04460nam 22005415 450 991015044970332120200714014208.03-662-48918-X10.1007/978-3-662-48918-5(CKB)3710000000943198(DE-He213)978-3-662-48918-5(MiAaPQ)EBC4734215(PPN)197133215(EXLCZ)99371000000094319820161107d2016 u| 0gerurnn|008mamaatxtrdacontentcrdamediacrrdacarrier3000 Jahre Analysis Geschichte - Kulturen - Menschen /von Thomas Sonar2nd ed. 2016.Berlin, Heidelberg :Springer Berlin Heidelberg :Imprint: Springer Spektrum,2016.1 online resource (XXIV, 712 S. 383 Abb., 259 Abb. in Farbe.)

Jahrhundert -- Newton und Leibniz - Giganten und Widersacher -- Absolutismus, Aufklärung, Aufbruch zu neuen Ufern -- Auf dem Weg zu begrifflicher Strenge im 19. Jahrhundert -- An der Wende zum 20. Jahrhundert: Mengenlehre und die Suche nach dem wahren Kontinuum -- Ein Kreis schließt sich: Infinitesimale in der Nichtstandardanalysis -- Analysis auf Schritt und Tritt -- Literatur -- Abbildungsverzeichnis -- Personenregister -- Sachwortregister.Was ist eigentlich Analysis? Was sind unendlich kleine und unendlich große Größen, Indivisible und Infinitesimale? Was bedeuten Begriffe wie reelle Zahl, Stetigkeit, Kontinuum, Differential und Integral? Die Antwort gibt dieses Buch: Ausführlich werden darin Entstehung und Entwicklung dieser grundlegenden Begriffe des von Euler "Analysis des Unendlichen" genannten Teilgebietes der Mathematik von der Antike bis heute beschrieben, durch viele Figuren und farbige Abbildungen illustriert und in Tabellen zusammengefasst. All dies wird eingebettet in die historischen und kulturellen Ereignisse der einzelnen Epochen, die Lebensläufe der um Erkenntnis ringenden Gelehrten und kurze Einblicke in die von ihnen entwickelten modernen Teilgebiete der Analysis sowie deren Anwendungen in fast allen Bereichen unseres Lebens. Dieser Band ist eine wertvolle Fortsetzung der Reihe "Vom Zählstein zum Computer", von dem der Wissenschaftshistoriker E. Knobloch sagt, es sei eine Lust, dieses Buch zu lesen. Stimmen zur 1. Auflage "Drei Wünsche auf einmal erfüllt. Das Buch "3000 Jahre Analysis" ist alles andere als ein[e] trockene Aneinanderreihung von mathematischen Fakten und Formeln: Es ist vielmehr eine gelungene Mischung aus Lehr-, Sach- und Geschichtsbuch in einem, das sehr anschaulich und lebendig geschrieben ist. Der Autor Thomas Sonar hat es verstanden, die Geschichte der Analysis anschaulich, spannend und voller interessanter Details aufzuschreiben." Florian Modler, Spektrum der Wissenschaft "Das Buch […] ist einfach wunderbar. Jeder […] nimmt natürlich mit einer gewissen Erwartung dieses Buch in die Hand, und man wird nicht enttäuscht! ... Es macht wirklich Spaß, in dem Buch zu schmökern." Peter Littelmann, Mitteilungen der DMV Herausgeber Projektgruppe Geschichte der Mathematik der Universität Hildesheim H.-W. Alten Kl.-J.

In the near future, electrical energy will be provided and handled by power electronics and consumed through power electronics; this not only will intensify the role of power electronics technology in power conversion processes, but also implies that power systems are undergoing a paradigm shift, from centralized distribution to distributed generation. Today, more than 1000 GW of renewable energy generation sources (photovoltaic (PV) and wind) have been installed, all of which are handled by power electronics technology. The main aim of this book is to highlight and address recent breakthroughs in the range of emerging applications in power electronics and in harmonic and electromagnetic interference (EMI) issues at device and system levels as discussed in ‎robust and reliable power electronics technologies, including fault prognosis and diagnosis technique stability of grid-connected converters and ‎smart control of power electronics in devices, microgrids, and at system levels.Q-factorlithium-ion power battery packelectromagnetic field (EMF)expert systemstotal harmonic distortion (THD)current-fed
