Noise and Vibration Mitigation for Rail Transportation Systems
This volume contains the contributions to the 9th International Workshop on Railway Noise, held Sept 04-08, 2007, in Munich, Germany. The workshop featured lectures by international leaders in the field of railway noise and vibration. All subjects relating to railway noise as noise sources (rolling noise, aerodynamic noise, bridge noise, sonic boom), prediction tools and theoretical models, new noise reduction, technology as well as ground-borne vibration are tackled.

Numerical Simulation of Turbulent Flows and Noise Generation
Large Eddy Simulation (LES) is a high-fidelity approach to the numerical simulation of turbulent flows. Recent developments have shown LES to be able to predict aerodynamic noise generation and propagation as well as the turbulent flow, by means of either a hybrid or a direct approach. This book is based on the results of two French/German research groups working on LES simulations in complex geometries and noise generation in turbulent flows. The results provide insights into modern prediction approaches for turbulent flows and noise generation mechanisms as well as their use for novel noise reduction concepts.
Yen Path
World renowned wellness coach and yoga instructor Jenny Gallagher has developed a revolutionary new approach to getting motivated and achieving dreams. In Yen Path: Taking Steps Towards What You Want in Life, Jenny approaches her life changing concepts as she would approach a yoga class. By combining the best past, present, and future motivational concepts, Jenny will help you learn to: Create a deeper understanding of what you want Manage stress Have a life/work balance Relax and find joyYen Path uses yoga in a holistic approach that encourages positive thought and action. Jenny explains yoga concepts as they relate to the benefits of stillness, balance, observation, nonjudgment, intention, perception, metaphysical laws, energetic patterns, biological characteristics, nutrition, exercise, wisdom, and gratitude. Her approach is logical, geared toward the professional, and leaves no stone unturned.
