Download or read book The Differential Effects of Position Velocity and Acceleration Feedback on Motivation Over Time written by Daniel Jacob Watola and published by . This book was released on 2005 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper is concerned with the definition and application of position, velocity, and acceleration performance information as feedback. Specifically, it examines individuals' affective, behavioral, and cognitive reactions to feedback frames over time and across two contrasting performance profiles. Repeated measures MANCOVA supported a performance profile x time interaction for state positive affect, task self-efficacy, satisfaction with performance, and goal commitment. Simple effects analyses indicated that participants' indicators of task motivation increased over time in the accelerating performance profile, but decreased over time in the decelerating performance profile. A three-way interaction between feedback frame, performance profile, and time was not supported as hypothesized.

Download or read book Escape Velocity Better Metrics for Agile Teams written by Doc Norton and published by OnBelay Consulting, LLC. This book was released on 2020-02-02 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: Velocity is the most commonly used metric in agile software delivery. It is also perhaps the least effective metrics in agile software delivery. In "Escape Velocity", Doc Norton walks the reader through common issues with metrics and how to avoid them, altermative metrics that not only help agile teams perform better, but enable them to continuously improve, and techniques for forecasting that vastly outperform the use of velocity. In a quirky, casual, and information dense style, Doc Norton makes the topic of tracking data entertaining and shows us how to be more effective in the pursuit of excellent software.

Available in PDF, EPUB and Kindle. Book excerpt: "Smart" materials respond to environmental stimuli with particular changes in some variables. For that reason they are often also called responsive materials. Depending on changes in some external conditions, "smart" materials change either their properties (mechanical, electrical, appearance), their structure or composition, or their functions. Mostly, "smart" materials are embedded in systems whose inherent properties can be favourably changed to meet performance needs. Smart materials and structures have widespread applications in: 1. Materials science: composites, ceramics, processing science, interface science, sensor/actuator materials, chiral materials, conducting and chiral polymers, electrochromic materials, liquid crystals, molecular-level smart materials, biomaterials. 2. Sensing and actuation: electromagnetic, acoustic, chemical and mechanical sensing and actuation, single-measurand sensors, multiplexed multimeasurand distributed sensors and actuators, sensor/actuator signal processing, compatibility of sensors and actuators with conventional and advanced materials, smart sensors for materials and composites processing. 3. Optics and electromagnetics: optical fibre technology, active and adaptive optical systems and components, tunable high-dielectric phase shifters, tunable surface control. 4.

Book excerpt: Classical Feedback Control with Nonlinear Multi-Loop Systems describes the design of high-performance feedback control systems, emphasizing the frequency-domain approach widely used in practical engineering. It presents design methods for high-order nonlinear single- and multi-loop controllers with efficient analog and digital implementations. Bode integrals are employed to estimate the available system performance and to determine the ideal frequency responses that maximize the disturbance rejection and feedback bandwidth. Nonlinear dynamic compensators provide global stability and improve transient responses. This book serves as a unique text for an advanced course in control system engineering, and as a valuable reference for practicing engineers competing in today’s industrial environment.

Download or read book IUTAM Symposium on Chaotic Dynamics and Control of Systems and Processes in Mechanics written by Giuseppe Rega and published by Springer Science & Business Media. This book was released on 2005-03-10 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: The interest of the applied mechanics community in chaotic dynamics of engineering systems has exploded in the last fifteen years, although research activity on nonlinear dynamical problems in mechanics started well before the end of the Eighties. It developed first within the general context of the classical theory of nonlinear oscillations, or nonlinear vibrations, and of the relevant engineering applications. This was an extremely fertile field in terms of formulation of mechanical and mathematical models, of development of powerful analytical techniques, and of understanding of a number of basic nonlinear phenomena. At about the same time, meaningful theoretical results highlighting new solution methods and new or complex phenomena in the dynamics of deterministic systems were obtained within dynamical systems theory by means of sophisticated geometrical and computational techniques. In recent years, careful experimental studies have been made to establish the actual occurrence and observability of the predicted dynamic phenomena, as it is vitally needed in all engineering fields. Complex dynamics have been shown to characterize the behaviour of a great number of nonlinear mechanical systems, ranging from aerospace engineering applications to naval applications, mechanical engineering, structural engineering, robotics and biomechanics, and other areas. The International Union of Theoretical and Applied Mechanics grasped the importance of such complex phenomena in the Eighties, when the first IUTAM Symposium devoted to the general topic of nonlinear and chaotic dynamics in applied mechanics and engineering was held in Stuttgart (1989).
