Free Download Spatial Cognition: An Interdisciplinary Approach to Representing and Processing Spatial Knowledge by Christian Freksa, Christopher Habel, Karl F. Wender English | PDF | 1998 | 486 Pages | ISBN : 3540646035 | 14 MB Research on spatial cognition is a rapidly evolving interdisciplinary enterprise for the study of spatial representations and cognitive spatial processes, be they real or abstract, human or machine. Spatial cognition brings together a variety of - search methodologies: empirical investigations on human and animal orientation and navigation; studies of communicating spatial knowledge using language and graphical or other pictorial means; the development of formal models for r- resenting and processing spatial knowledge; and computer implementations to solve spatial problems, to simulate human or animal orientation and navigation behavior, or to reproduce spatial communication patterns. These approaches can interact in interesting and useful ways: Results from empirical studies call for formal explanations both of the underlying memory structures and of the processes operating upon them; we can develop and - plement operational computer models obeying the relationships between objects and events described by the formal models; we can empirically test the computer models under a variety of conditions, and we can compare the results to the - sults from the human or animal experiments. A disagreement between these results can provide useful indications towards the re nement of the models.  Free Download Southern African Moths & their Caterpillars by Hermann Staude, Mike Picker, Charles Griffiths English | September 19th, 2023 | ISBN: 1784273473 | 368 pages | True EPUB | 524.19 MB Southern Africa boasts wonderful invertebrate diversity and abundance. In this book, approximately 1,500 species of the region's moths - and most of their caterpillars - are illustrated with images of live specimens. A diagnosis based on visible characters is provided, also enabling the user to readily identify many closely related species not illustrated. Known host associations, habitat preferences, phenology and accurate distribution maps are provided for each species.  Free Download Soft and Stiffness-controllable Robotics Solutions for Minimally Invasive Surgery: The STIFF-FLOP Approach by Jelizaveta Konstantinova English | PDF | 2018 | 420 Pages | ISBN : 8793519729 | 335.6 MB In Minimally Invasive Surgery (MIS), tools go through narrow openings and manipulate soft organs that can move, deform, or change stiffness. There are limitations on modern laparoscopic and robot-assisted surgical systems due to restricted access through Trocar ports, lack of haptic feedback, and difficulties with rigid robot tools operating inside a confined space filled with organs. Also, many control algorithms suffer from stability problems in the presence of unexpected conditions. Yet biological "manipulators", like the octopus arm can manipulate objects while controlling the stiffness of selected body parts and being inherently compliant when interacting with objects. STIFF-FLOP robot is an innovative soft robotic arm that can squeeze through a standard MIS, reconfigure itself and stiffen by hydrostatic actuation to perform compliant force control tasks while facing unexpected situations.  Free Download Soft Rock Mechanics and Engineering by Milton Kanji English | EPUB | 2020 | 750 Pages | ISBN : 3030294765 | 174 MB This book offers a practical reference guide to soft rock mechanics for engineers and scientists. Written by recognized experts, it will benefit professionals, contractors, academics, researchers and students working on rock engineering projects in the fields of civil engineering, mining and construction engineering.  Free Download Shred Happens: So Easy, So Good: 100+ Protein-Packed Mediterranean Favorites with a Low-Carb Twist; A Cookbook by Arash Hashemi English | March 18, 2025 | ISBN: 0593796535 | 256 pages | MOBI | 76 Mb NEW YORK TIMES BESTSELLER  Free Download Sequential Monte Carlo Methods in Practice by Arnaud Doucet, Nando Freitas, Neil Gordon English | PDF (True) | 2001 | 590 Pages | ISBN : 0387951466 | 51.1 MB Monte Carlo methods are revolutionising the on-line analysis of data in fields as diverse as financial modelling, target tracking and computer vision. These methods, appearing under the names of bootstrap filters, condensation, optimal Monte Carlo filters, particle filters and survial of the fittest, have made it possible to solve numerically many complex, non-standarard problems that were previously intractable. This book presents the first comprehensive treatment of these techniques, including convergence results and applications to tracking, guidance, automated target recognition, aircraft navigation, robot navigation, econometrics, financial modelling, neural networks,optimal control, optimal filtering, communications, reinforcement learning, signal enhancement, model averaging and selection, computer vision, semiconductor design, population biology, dynamic Bayesian networks, and time series analysis. This will be of great value to students, researchers and practicioners, who have some basic knowledge of probability. Arnaud Doucet received the Ph. D. degree from the University of Paris- XI Orsay in 1997. From 1998 to 2000, he conducted research at the Signal Processing Group of Cambridge University, UK. He is currently an assistant professor at the Department of Electrical Engineering of Melbourne University, Australia. His research interests include Bayesian statistics, dynamic models and Monte Carlo methods. Nando de Freitas obtained a Ph.D. degree in information engineering from Cambridge University in 1999. He is presently a research associate with the artificial intelligence group of the University of California at Berkeley. His main research interests are in Bayesian statistics and the application of on-line and batch Monte Carlo methods to machine learning.
