Download Agility kompakt: Tipps für erfolgreiche Systementwicklung by Peter Hruschka PDF

By Peter Hruschka

"Agility kompakt" zeigt eine replacement Sicht auf die Schwerpunkte in der software program- und Systementwicklung. Agilität richtet die Wertvorstellungen stärker auf die Zusammenarbeit von Menschen, auf mehr direkte Kommunikation, Ergebnisorientierung und rasches suggestions. Prozesse und Werkzeuge dürfen nicht fehlen, rücken aber in den Hintergrund.

Das Buch regt Sie an, aus dem Alltag der Software-Entwicklung aufzusehen und Ihre eigenen Praktiken im Licht agiler Grundsätze zu überprüfen. Lesen Sie, wie sich diese geänderten Wertvorstellungen auf alle Projektbeteiligten auswirken – von Auftraggebern und Kunden über die Projektleitung bis hin zu Analytikern, Designern und Programmierern.

Neu in der 2. Auflage: aktueller Stand der agilen Methoden und Hilfestellung für eine angemessene Mischung aus Agilität und Disziplin für Ihre Projekte.

Download Aktive Schalldämpfung in einem Kanal by Zhang M. PDF

By Zhang M.

The target of this paintings was once to boost adaptive and powerful non-adaptive controlalgorithms for energetic noise cancellation in a duct and to experimentally try out their performante within the cancellation of noise.To version the propagation of Sound within the duct, method identity methodsin the frequency area have been used. The excessive Order of the version and the will for energetic noise cancellation in a large frequency band provide upward thrust to numerical difficulties. a complicated identity strategy is built the following to unravel this challenge. The version bought is of Order forty four and indicates an excellent healthy with the measured info within the frequency variety from 20 Hz as much as a thousand Hz. The H, Synthesis procedure is used to layout the powerful non-adaptive controllers.Both suggestions controls, and feedforward controls, and the mix offeedforward and suggestions controls (2-DOF) were synthesized and verified. as a result of the time hold up of the secondary course, the functionality of the suggestions regulate is restricted. within the mixture of feedforward and suggestions keep an eye on, the feedforward Controller performs a dominant function. The functionality of the feedforward Controller is particularly depending on version error. however, the mix of feedforward and suggestions keep watch over indicates a greater functionality. For adaptive regulate, numerous identified tools, resembling FXLMS and FULMS, are brought. the main major merits of adaptive keep watch over are its feedforward constitution and its skill to conform to the alterations of the plant. the foremost challenge of the adaptive keep watch over is the trade-off among balance and convergence time. because the latest algorithms don't bear in mind the version errors of the secondary direction, the adaptive procedure is risky if the achieve within the model loop is huge. a brand new, powerful, and good FULMS set of rules has been derived and carried out. The experimental effects exhibit that the hot set of rules is either solid and swiftly tonverging.
