Kan det holde? Hvis din nye og dyre kontorstol går i stykker efter, at du har siddet i den få gange, ville du så købe den samme stol igen, og endda anbefale den til andre? Ved at anvende statik, styrke- og materialelære, når man konstruerer eller ombygger en konstruktion, kan man dimensionere den, så den kan holde til de forventede belastninger, der opstår når produktet anvendes.Dette er den anden bog i trilogien Grundlæggende konstruktion. Trilogien blev udviklet til forfatterens undervisning på Produktionteknolog uddannelse på Københavns Erhvervsakademi. Trilogien er udviklet, så den henvender sig til både ingeniører, arkitekter, maskinmestre, produktudviklere, konstruktører, designere, håndværkere, HTX-studerende og andre, der ønsker at lære eller få genopfrisket, hvordan man beregner styrken i ens konstruktioner.Bogen gennemgår teorien for den grundlæggende styrkelære og er opdelt over fire kapitler: Dimensionering, Profiler, Indre kræfter og Samlinger. Bogen gennemgår gode råd om konstruktion, bevidst svageste led, tyngdepunkt, inertimoment, modstandsmoment, fra kraft til spænding, de forskellige spændingstyper, samt nedbøjning, forskydnings- og momentkurver for simple bjælkekonstruktioner. Bogen afsluttes med bolte- og svejsesamlinger samt ti cases, hvor teorierne i bogen kan anvendes.

Vergleicht man das Leben, das Denken und die Schriften der alten Römer oder Griechen mit dem heutigen Leben, wird man keine wesentlichen Unterschiede in der Klarheit der Gedanken oder der Eloquenz der Erzählweise feststellen können. Vergleicht man jedoch die Technologien der alten Römer mit den heute bekannten Technologien, erkennt man, dass auf dem technischen Gebiet gewaltige Fortschritte geschaffen wurden. Entscheidende technische Fortschritte sind immer mit berühmten Erfindern und Wissenschaftlern verbunden. Diese prägen ihre Zeit und das Leben der nachfolgenden Generationen. Auf wichtigen technischen Durchbrüchen werden oft industrielle Imperien errichtet.Dieses Buch zeigt die technischen Aufgaben, denen sich die Erfinder gegenüber sahen, ihre Erfindungen und was aus diesen Erfindungen entstand. Das Buch soll Faszination für Technik vermitteln und zur wirtschaftlichen Realisierung eigener Erfindungen ermuntern, die zumeist durch das Anmelden der Erfindung zum Patent beginnt.

The monograph is devoted to the construction of the high-order finite difference and finite element methods for numerical solving multidimensional boundary-value problems (BVPs) for different partial differential equations, in particular, linear Helmholtz and wave equations, nonlinear Burgers¿ equations, and elliptic (Schrödinger) equation. Despite of a long history especially in development of the theoretical background of these methods there are open questions in their constructive implementation in numerical solving the multidimensional BVPs having additional requirement on physical parameters or desirable properties of its approximate solutions. Over the last two decades many papers on this topics have been published, in which new constructive approaches to numerically solving the multidimensional BVPs were proposed, and its highly desirable to systematically collect these results. This motivate us to write thus monograph based on our research results obtainedin collaboration with the co-authors. Since the topic is importance we believe that this book will be useful to readers, graduate students and researchers interested in the field of computational physics, applied mathematics, numerical analysis and applied sciences

This book provides a summary of the essential knowledge and working processes involved with control of rotating equipment including:machine characteristics;overall control strategies;detailed design; andbest practices.Emphasis is placed on the role of pumps and compressors as part of the overall process flow rather than treating them in isolation as this tends to optimize energy efficiency.Readers are made aware of the critical roles of rotating equipment and are given a good understanding of their dynamic behaviors, including surge/choke. The author imparts the practical know-how and skills involved in the design and implementation of capacity and anti-surge control and safe-guarding logic. Furthermore, the book discusses real-time monitoring of solutions based on operational requirements, dynamic models for control of supply and demand, cause-and-effect relationships, the useof online and offline data, and collaboration with other engineering disciplines. The text facilitates support for the day-to-day operation of in-house open-platform compressor control applications, encouraging the growth of analytic skills in troubleshooting and fixing common problems; it also inculcates a basic understanding of the principles of third-party proprietary technologies and supports decision-making between in-house and third-party solutions.Process engineers working in the oil-and-gas, refining, petrochemical, and chemical industries who bear responsibility for designing control solutions involving pumps and compressors will find this book an invaluable source of practical advice. This book also helps engineers working on design and maintenance of rotating equipment to understand the perspectives and requirements of process control.
