Book Description
Superposition of a small set of behaviors, learned via teleoperation, can lead to robust completion of a simple articulated reach-and-grasp task. Results support the hypothesis that a set of learned behaviors can be combined to generate new behaviors of a similar type. This supports the hypothesis that a robot can learn to interact purposefully with its environment through a developmental acquisition of sensory-motor coordination. Teleoperation bootstraps the process by enabling the robot to observe its own sensory responses to actions that lead to specific outcomes. A reach-and-grasp task, learned by an articulated robot through a small number of teleoperated trials, can be performed autonomously with success in the face of significant variations in the environment and perturbations of the goal. Superpositioning was performed using the Verbs and Adverbs algorithm that was developed originally for the graphical animation of articulated characters. Work was performed on Robonaut at NASA-JSC.

Book Description
Parallel Kinematic Machines (PKMs) are one of the most radical innovations in production equipment. They attempt to combine the dexterity of robots with the accuracy of machine tools to respond to several industrial needs. This book contains the proceedings of the first European-American Forum on Parallel Kinematic Machines, held in Milan, Italy from 31 August - 1 September 1998. The Forum was established to provide institutions, technology suppliers and industrial end users with an improved understanding of the real advantages to be gained from using PKMs. This book contributes to a mid-term strategy oriented to reduce time to market and costs, improve production flexibility and minimize environmental impacts to increase worldwide competitiveness. In particular the authors focus on enabling technologies and emerging concepts for future manufacturing applications of PKMs. Topics include: Current status of PKM R&D in Europe, the USA and Asia. Industrial requirements, roadblocks and application opportunities. Research issues and possibilities. Industrial applications and requirements.

Book Description
This book is dedicated to the latest findings on the design and optimization of production lines. The “Fourth Industrial Revolution” (alternatively known as “Industry 4.0”) supports innovative models for energy consumption and fault tolerance in automated lines, and this drives changes in the design and optimization models of production lines. The goal is to collect a series of works that can summarize the latest trends in the field of production line optimization models in order to improve the responsiveness of automated lines to failures, reduce energy consumption and peak electricity demand, and develop other methods to support robust and sustainable production lines.

"A major constraint to adoption of improved resource-conserving cropping systems in developing countries is the lack of simple planting equipment. This manual provides a valuable reference for research and extension personnel engaged in the selection, adaptation and/or construction of complete planters appropriate to specific soil, crop, climate and residue conditions"--ACIAR website.

Book Description
This book responds to the widespread recognition among experts that our educational system needs to change in order to provide the skills and knowledge necessary to ensure the future vitality of U.S. agriculture. Understanding Agriculture focuses on agricultural literacy (education about agriculture) and vocational agricultural education (education in agriculture). The section on agricultural literacy addresses the teaching of science through agriculture, teacher education and training, model educational programs, community support, and agricultural career exploration programs. Vocational agricultural education is examined in terms of program enrollment, availability and content, supervised occupational experiences, the Future Farmers of America program, and teacher education and supply.

Book Description
The Protective Arm of the Renin Angiotensin System: Functional Aspects and Therapeutic Implications is the first comprehensive publication to signal the protective role of a distinct part of the renin–angiotensin system (RAS), providing readers with early insight into a complex system which will become of major medical importance in the near future. Focusing on recent research, The Protective Arm of the Renin Angiotensin System presents a host of new experimental studies on specific components of the RAS, namely angiotensin AT2 receptors (AT2R), the angiotensin (1–7) peptide with its receptor Mas, and the enzyme ACE 2, which exert significant beneficial, health-promoting actions by counterbalancing the well-known harmful arm of the RAS with its classical angiotensin AT1 receptor. This innovative concept of the protective arm of the RAS, examined in this reference, represents an indispensable background and will be a strong support for biomedical students, researchers, cardiologists, surgeons, nephrologists, diabetologists, and endocrinologists, as well as any other physician or researcher concerned with RAS physiology, pathophysiology and clinical implications. - Provides a complete understanding of the protective side of the Renin Angiotensin System (RAS) involving angiotensin AT2 receptor, ACE2, and Ang(1-7)/Mas receptor - Combines the knowledge of editors who pioneered research on the protective renin angiotensin system including; Dr. Thomas Unger, one of the founders of AT2 receptor research; Dr. Ulrike M. Steckelings, who contributed significantly to first preclinical studies with a novel specific AT2-agonist, and Dr. Robson Santos who pioneered research on angiotensin-(1-7) and its receptor Mas. - Shows that the protective RAS axes are able to ameliorate the course of several cardiovascular, renal, metabolic and neurological diseases - Provides the basis for the understanding of a novel therapeutic approach to stimulate components of the protective arm of the RAS.

Book Description
'Landscapes in Between' is a unique collaborative of paintings and memories. From the Mornington Peninsula in Australia to Lake Como in Italy, artist Sophie Perez has travelled through the eyes of others capturing a unique and personal moment in their lives through paint. Each painting was created from a photo sent to Sophie and accompanied by stories of love, loss and hope. The project was a direct response to the challenges facing our world today, intended to bring people comfort and beauty at a time of incredible uncertainty, but through it, connections were made from the sharing of memories and stories of which Sophie now feels part of.Landscapes in Between is rich with nostalgia, full of hope and brimming with love.

Book Description
This book is dedicated to “High-Performance Eco-Efficient Concrete” and concrete fatigue behavior, more sustainable construction materials, capable of complying with quality standards and current innovation policies, aimed at saving natural resources and reducing global pollution. The development of self-compacting concretes with electric arc furnace slags is a further achievement. In addition, the technical and economic viability of using coarse recycled aggregates from crushed concrete in shotcrete, enhanced quality and reduced on-site construction time are the basic features of prefabricated bridge elements and systems, biomass bottom ash as aluminosilicate precursor and phosphogypsum were discussed. On the other hand, basalt fiber improving the mechanical properties and durability of reactive powder concrete, alkali-activated slag and high-volume fly ash and the potential of phosphogypsum as secondary raw material in construction industry, the effects of fly ash on the diffusion, bonding, and microproperties of chloride penetration in concrete were studied. Increasing amounts of sustainable concretes are being used as society becomes more aware of the environment. Finally, the circular economy as an economic model of production and consumption that involves reusing, repairing, refurbishing, and recycling materials after their service life are presented in this book.
