Download The ETTO Principle: Efficiency-Thoroughness Trade-Off by Erik Hollnagel PDF

By Erik Hollnagel

Coincidence research and hazard review have for many years eager about the human issue, fairly 'human error'. numerous books and papers were written approximately the best way to determine, classify, cast off, hinder and atone for it. This bias in the direction of the learn of functionality disasters, ends up in a overlook of standard or 'error-free' functionality and the idea that as mess ups and successes have diverse origins there's little to be won from learning them jointly. Erik Hollnagel believes this assumption is fake and that security can't be attained merely by means of disposing of hazards and screw ups. The ETTO precept appears on the universal trait of individuals at paintings to regulate what they do to check the stipulations - to what has occurred, to what occurs, and to what may well ensue. It proposes that this efficiency-thoroughness trade-off (ETTO) - often sacrificing thoroughness for potency - is common. whereas on occasion the changes could lead to hostile results, those are as a result of the exact same techniques that produce successes, instead of to mistakes and malfunctions. The ETTO precept eliminates the necessity for specialized theories and versions of failure and 'human blunders' and provides a potential foundation for powerful and simply ways to either reactive and proactive security administration.

Download Evaluation of U.S. Air Force Preacquisition Technology by National Research Council, Division on Engineering and PDF

By National Research Council, Division on Engineering and Physical Sciences, Air Force Studies Board, Committee on Evaluation of U.S. Air Force Preacquisition Technology Development

From the times of biplanes and open cockpits, the air forces of the USA have trusted the mastery of know-how. From layout to operation, a undertaking can stretch to twenty years and extra, with non-stop raises in fee. a lot of the hold up and price development afflicting smooth usa Air strength (USAF) courses is rooted within the incorporation of complicated expertise into significant structures acquisition. Leaders within the Air strength accountable for technological know-how and know-how and acquisition try to figure out the optimum approach to make the most of current regulations, strategies, and assets to correctly record and execute pre-program of list expertise improvement efforts, together with possibilities to facilitate the quick acquisition of innovative services and the extra planned acquisition of evolutionary functions. evaluate of U.S. Air strength Preacquisition expertise improvement responds to this desire with an exam of the present country of Air strength expertise improvement and the surroundings during which know-how is received. The booklet considers most sensible practices from either govt and to distill applicable ideas that may be applied in the USAF.

Download Konstruieren von Pkw-Karosserien : Grundlagen, Elemente und by Jörg Grabner, Richard Nothhaft PDF

By Jörg Grabner, Richard Nothhaft

Die Faszination, die vom vehicle ausgeht, ist und bleibt ungebrochen. Entsprechend interessant ist es, sich vor dem Hintergrund konventioneller Konstruktionstechniken über die virtuelle Produktentwicklung von Pkw-Karosserien an modernen CAD-Arbeitsplätzen informieren zu können. Die Autoren führen in die Grundlagen ein und zeigen anhand von Beispielen und zahlreichen Abbildungen, wie mit dem procedure CATIA der Rohbau sowie die Ausstattung innen und außen konstruiert werden. Darüber hinaus wird das so genannte "Package" an Beispielen beschrieben, additionally das administration und die Harmonisierung der Anforderungen an die Bauräume (z.B. Motor-, Innen- und Kofferraum, Unterflur) sowie die Verwaltung aller Geometriedaten des Gesamtfahrzeugs und die Sicherstellung ihrer Aktualität. In der three. Auflage wird insbesondere der aktuellen CAD-Anwendung CATIA V5 an ausgewählten Beispielen Rechnung getragen.

Download Piezoelectric Shells: Distributed Sensing and Control of by H.S. Tzou PDF

By H.S. Tzou

Exploiting new complicated buildings and electromechanical platforms, e. g. , adaptive buildings, high-precision platforms, micro electromechanical platforms, allotted sensors/actuators, precision manipulation and controls, and so forth. , has been turning into one of many mainstream examine and improvement actions (structure & movement) lately. those new structures and units may well convey a brand new technological revolution in glossy industries and additional, at once or in a roundabout way, effect human existence. within the look for and study in leading edge applied sciences, it really is proved that piezoelectric fabrics are very flexible in either sensor and actuator functions. for that reason, piezoelectric expertise has been greatly utilized to a great number of business functions and units, various from thin-film micro sensors/actuators to giant house constructions as well as these particularly traditional purposes, e. g. , sensors, actuators, hydrophones, precision manipulators, cellular robots, micro automobiles, and so on. there were a couple of books on piezoelectricity released some time past; even though, a unified presentation of piezoelectric shells and disbursed senSing/control functions remains to be missing. This publication is meant to fill the space and to pro~de practicing engineers and researchers with an advent to complicated piezoelectric shell theories and dispensed sensor/actuator applied sciences in structural identity and keep an eye on. This ebook represents a set of the author's contemporary learn and improvement on piezoelectric shells and similar functions to disbursed size and keep an eye on of continuaj it displays six best-paper awards, together with [ xviii] • Contents.
