Many approaches have been proposed to enhance software productivity and reliability. These approaches typically fall into three categories: the engineering approach, the formal approach, and the knowledge-based approach. The optimal gain in software productivity cannot be obtained if one relies on only one of these approaches. Thus, the integration of different approaches has also become a major area of research.
This book is a How To guide for modeling population dynamics using Integral Projection Models (IPM) starting from observational data. It is written by a leading research team in this area and includes code in the R language (in the text and online) to carry out all computations. The intended audience are ecologists, evolutionary biologists, and mathematical biologists interested in developing data-driven models for animal and plant populations. IPMs may seem hard as they involve integrals. The aim of this book is to demystify IPMs, so they become the model of choice for populations structured by size or other continuously varying traits. The book uses real examples of increasing complexity to show how the life-cycle of the study organism naturally leads to the appropriate statistical analysis, which leads directly to the IPM itself. A wide range of model types and analyses are presented, including model construction, computational methods, and the underlying theory, with the more technical material in Boxes and Appendices. Self-contained R code which replicates all of the figures and calculations within the text is available to readers on GitHub.

This book describes 15 important qualities which one needs to have in order to be considered a model Christian. It also guides the reader through a series of user-friendly, practical exercises that will help them to become a model Christian. When these qualities are developed, they turn the believer into a beautiful rose that beautifies and perfumes his/her environment. The believer in Christ has to decide not so much what are the virtues and values that set them apart from other people of faith and religion. He or she has to decide whether they will practice the principles. This book summarizes the core Christian virtues and encourages the believer to see that even the least confident Christian can develop into a model worthy of Christ and of the admiration of others believers. The virtues which are described in this book are inner qualities that are born out of principles which the Bible teaches. However, they emphasize the teachings of Jesus and the applications of the apostle Paul. In this book, Christians are not let off the hook; and yet they are made to feel confident and supported by the way the author paves the way of hope. The virtues discussed in this book deal with personal and internal qualities. While doing this, it delves into issues of interpersonal relationships, business efforts, and family dynamics. A lot of suggestions are given for personal development.
Intended to help anyone who teaches, this book has something of a cult following. Drawing on extensive teaching experience, the author presents a personal account of good practice, written in an engaging and accessible style and based on extensive scholarly sources.
A smart rotor is a wind turbine rotor that, through a combination of sensors, control units and actuators actively reduces the variation of the aerodynamic loads it has to withstand. Smart rotors feature promising load alleviation potential and might provide the technological breakthrough required by the next generation of large wind turbine rotors.
The book presents the aero-servo-elastic model of a smart rotor with Adaptive Trailing Edge Flaps for active load alleviation and provides an insight on the rotor aerodynamic, structural and control modeling. A novel model for the unsteady aerodynamics of an air foil section with flap is presented and coupled with a multi-body structural representation. A smart rotor configuration is proposed, where the Adaptive Trailing Edge Flaps extend along the outer 20 % of the blade span. Linear Quadratic and Model Predictive algorithms are formulated to control the flap deflection. The potential of the smart rotor is finally confirmed by simulations in a turbulent wind field. A significant reduction of the fatigue loads on the blades is reported: the flaps, which cover no more than 1.5 % of the blade surface, reduce the fatigue load by 15 %; a combination of flap and individual pitch control allows for fatigue reductions up to 30 %.
