Book Description
The expert guide to biodynamic farming and gardening. In this revised and updated edition of Grasp the Nettle Peter Proctor tells the reader how to apply biodynamic methods of farming and gardening to a wide range of conditions in New Zealand and in other countries. The book provides practical observations and techniques, and relates these to the spiritual scientific knowlege upon which that biodynamic practice is based. Peter gives tips on how to recognise healthy soil and pasture, and on how to make your own biodynamic preparations. He also gives examples of farms that are successfully using biodynamic methods. This book aims to assist biodynamic farmers and gardeners to observe the processes of life and growth, and to understand how these processes are governed by cosmic forces, so they can use this knowlege in applying their practical skills. Peter Proctor, past national field advisor for the NZ Bio Dynamic Farming and Gardening Association, now teaches and advises farmers on biodynamic methods around the world.

Book Description
The simple task of grasping objects has been studied for centuries by scientists, therapists and engineers who have tried to understand and duplicate the versatility of the human hand. Using an interdisciplinary approach and new framework for looking at prehension, the authors uncover the subleties of the amazing interaction between the hand and the brain. They draw from such diverse fields as experimental psychology, kinesiology, robotics, neural networks, artificial intelligence, neuropsychology and rehabilitation. A triangle strategy is presented, starting from conceptual models that suggest both experimental and computational models. Chapters describe the multiple postures established by the hand, phases in the dynamic process of reaching for, grasping and manipulating various objects, and the constraints acting on such activity. Appendices provide the complete anatomy of the upper limb, the basics of computational modelling, and the fundamentals of prosthetic and dextrous robot hands. The ultimate goal of this book is to develop a common vocabularly for multidisciplinary researchers who strive to understand a system as complex as the hand under the control of the human brain.

Book Description
Abstract: Various movement parameters of grasping movements, like velocity or type of the grasp, have been successfully decoded from neural activity. However, the question of movement event detection from brain activity, that is, decoding the time at which an event occurred (e.g. movement onset), has been addressed less often. Yet, this may be a topic of key importance, as a brain-machine interface (BMI) that controls a grasping prosthesis could be realized by detecting the time of grasp, together with an optional decoding of which type of grasp to apply. We, therefore, studied the detection of time of grasps from human ECoG recordings during a sequence of natural and continuous reach-to-grasp movements. Using signals recorded from the motor cortex, a detector based on regularized linear discriminant analysis was able to retrieve the time-point of grasp with high reliability and only few false detections. Best performance was achieved using a combination of signal components from time and frequency domains. Sensitivity, measured by the amount of correct detections, and specificity, represented by the amount of false detections, depended strongly on the imposed restrictions on temporal precision of detection and on the delay between event detection and the time the event occurred. Including neural data from after the event into the decoding analysis, slightly increased accuracy, however, reasonable performance could also be obtained when grasping events were detected 125 ms in advance. In summary, our results provide a good basis for using detection of grasping movements from ECoG to control a grasping prosthesis

Book Description
Anatomical guide leverages exceptional dissection images to elucidate the biomechanics of the hand and upper extremity The hand is a unique instrument that executes the commands of the brain and expresses the nuances of the mind. The Grasping Hand: Structural and Functional Anatomy of the Hand and Upper Extremity by Amit Gupta and Makoto Tamai is a state-of-the-art book that details the functions of the hand to feel, receive, gather, collect and hold, as well as the complex role that the whole upper extremity plays in enabling these actions. The anatomical structures intrinsic to these functions are detailed through illuminating cadaveric dissections and succinct text. Organized in 5 sections and 38 chapters, the book begins with a chapter detailing the intriguing history of hand anatomy, followed by a section encompassing the structural and functional fundamentals. The third section covers general anatomy and function, with discussions of the nerves and vascularity of the upper extremity, as well as the brachial plexus. The fourth section features 26 anatomically organized chapters from the shoulder to the fingertip with anatomical and functional insights on the joints, fascia and retinacula, interosseus membrane, tendons and more. The single chapter comprising the final section covers imaging and anatomy. Key Highlights Pioneers in modern hand surgery share vast collective knowledge and pearls on hand and upper extremity anatomy and biomechanics Over 1,100 exquisite, original dissections of lightly embalmed fresh cadaveric arms provide unique visual insights about underlying tissues and structures High quality, never before published original photographs enhance understanding of anatomy, physiology, and pathology This practical resource is ideal for reviewing anatomy and biomechanics prior to performing hand, wrist, arm, elbow, and shoulder surgery, making it essential reading for orthopaedic surgeons, fellows, and hand specialists. This book is also useful for students of human anatomy, physical and occupational therapists, medical students, and anyone interested in upper extremity anatomy and function.

Book Description
Research about tasks that robotic maids should be able to perform is an emerging research area such as cooking and cleaning. Among them, manipulation of clothes is one of the hardest tasks due to the fact that textile is highly deformable and it is hard to model a good grasping point on them. In literature there are certain algorithms depending on 3D information of the cloth but most of them are not robust. Among them, Fast Integral Normal 3D (FINDDD) descriptors is a promising way for finding grasping points around previously detected collar of a polo shirt but, it fails to select the position in the best way possible. In this work, an improvement to the FINDDD descriptor selected grasping points, using vector autoregression model is proposed. Previously calculated FINDDD scores will be used as features and the system will be able to find a grasping position which is better to grasp a polo shirt. With better grasping positions, the robot will be able to perform further tasks such as folding, hanging to a hook etc. To train the system, a training set is formed from the samples of the simplest placement of the polo shirt. Then, the trained system is tested on 7 different positions and placements of the polo shirt. To form the training set, we have developed a new interaction method based on the use of a sensor that captures natural hand movements. With use of this method, the robot is teleoperated using natural hand movements instead of direct manipulation or haptic devices as usage of natural hand movements enhances the user experience and eases the data collection process. The system is evaluated based on the distance between the user given grasp positions and the system output grasp positions. Further evaluation is done by checking whether the new grasping positions indeed better positions by analysing the real world images. Even though, the system works well for the spread open cases, the results obtained are prone to placement changes especially when wrinkles are introduced.
