Development of Geocentric Spatial Language and Cognition




Development of Geocentric Spatial Language and Cognition: An Eco-cultural Perspective by Pierre R. Dasen


English | 12 Aug. 2010 | ISBN: 052119105X | 408 Pages | PDF | 4 MB




Egocentric spatial language uses coordinates in relation to our body to talk about small-scale space ("put the knife on the right of the plate and the fork on the left"), while geocentric spatial language uses geographic coordinates ("put the knife to the east, and the fork to the west").

Beta cell replacement through transplantation remains the only treatment option for Type 1 diabetes enabling restoration of near-physiological glucose levels without significant hypoglycemia.

Drives and Control for Industrial Automation




Kok Kiong Tan, "Drives and Control for Industrial Automation"


English | ISBN: 1848824246, 1447126068 | 2011 | 200 pages | PDF | 5 MB




Drives and Control for Industrial Automation presents the material necessary for an understanding of servo control in automation. Beginning with a macroscopic view of its subject, treating drives and control as parts of a single system, the book then pursues a detailed discussion of the major components of servo control: sensors, controllers and actuators. Throughout, the mechatronic approach – a synergistic integration of the components – is maintained, in keeping with current practice.




The authors" holistic approach does not preclude the reader from learning in a step-by-step fashion – each chapter contains material that can be studied separately without compromising understanding. Drives are described in several chapters according to the way they are usually classified in industry, each comprised of its actuators and sensors. The controller is discussed alongside. Topics of recent and current interest – piezoelectricity, digital communications and future trends – are detailed in their own chapters.
