This book describes Probabilistic Logic Networks (PLN), a novel conceptual, mathematical and computational approach to uncertain inference. In order to carry out effective reasoning in real-world circumstances, AI software must robustly handle uncertainty. However, previous approaches to uncertain inference do not have the breadth of scope required to provide an integrated treatment of the disparate forms of cognitively critical uncertainty as they manifest themselves within the various forms of pragmatic inference. Going beyond prior probabilistic approaches to uncertain inference, PLN is able to encompass within uncertain logic such ideas as induction, abduction, analogy, fuzziness and speculation, and reasoning about time and causality. The book reviews the conceptual and mathematical foundations of PLN, giving the specific algebra involved in each type of inference encompassed within PLN. Inference control and the integration of inference with other cognitive faculties are also briefly discussed.

Presents an original body-mind model which explains in clear, non-academic prose the causes, treatment and prevention of activity-related (posture-movement-related) back pain. Details a continuum of therapy and education to deal with such problems. Provides self-care guidelines for controlling pain and improving posture. The self-care principles apply not only to back pain but to other musculoskeletal problems as well..

In "Dare to Inquire" Bruce Kodish surveys the spectrum from closed, dogmatic, fundamentalist systems to open, skeptical, humanistic ones. He provides means, using general semantics, for promoting openness in oneself and others. Applications are made to religion, ethics, science and other areas of life..

From the author: We discuss the viscoelastic flow of the matrix fluid in an Extensional Flow Mixer (EFM) obtained by a numerical simulation. The effect of the fluid viscoelasticity on the flow state in an EFM was considered by the comparison of the flow states of the purely viscous fluid and the viscoelastic fluid. The mixing performance of the EFM is also considered. The Phan-Thien Tanner model was used as the constitutive equation of the viscoelastic fluid and the Carreau model was used as that of the purely viscous fluid. Results obtained are as follows: 1) Stagnation flows occur in the converging-diverging plates (c-d plates) in the case of viscoelastic fluid. The size of stagnation flow region becomes large when the fluid has a strain-thickening elongational viscosity. 2) The absolute value of the extensional strain and the pressure drop in the c-d region increase with fluid elasticity. Meanwhile, the residence time in the c-d region decreases with that. 3) There is no stagnation region in the c-d plates for a purely vis cous fluid. The stagnation flow has an effect on the estimation value of EFM's performance. The prediction by the purely viscous fluid is not useful for the flow in an EFM because of extremely low accuracy.
