Foundations of Artiicial Intelligence presents a number of chapters from major players in artiicial intelligence (AI) that discuss fundamental assumptions underlying the dominant approaches to AI today. Perhaps the best parts of the book are the critiques: each chapter is followed by an in-depth critique that evaluates the utility of those assumptions in pursuing the goal of AI. But what is the...

background and objectives: lipases are valuable biocatalysts which are widely used in the detergent, food, dairy and pharmaceutical industries. the aims of the present study included the isolation of a lipase-producer from industrial zones and the partial characterization of the enzyme. materials and methods: a number of bacteria were isolated from sites related to the oil industries. an isolat...

the interaction of bovine serum albumin ( bsa) and egg albumin with water solublephthalocyanine, cobalt (ιι) 4, 4′ , 4′′, 4′′′- tetrasulfophthalocyanine ( cotspc) , has been studiedby the uv- vis method at ph 7.0 and five different temperatures 20, 25, 30, 35 and 40°c. theformation constants have been elucidated by using spectrophotometric titration and computersquad program data refinement. th...

a spectrophotometric method is used to determine the acidity constants of some derivatives of 9,10-anthraquinone in binary methanol-water mixtures at 25 °c. there is a linear inverse relationship between pka of all acids and the mole fraction of methanol in the mixed solvent. the influence of substituents in the molecular structure on the ionization constants is discussed.

The last few decades have witnessed the development of a host of ideas aimed at understanding and predicting nature’s ever present complexity (see for instance, Mandlebrot, 1982; Bak, 1996; Wolfram, 2002). It is shown that such a work provides, through its detailed study of order and disorder, a suitable framework for visualizing the dynamics and consequences of mankind’s ever present divisive ...

In this paper, we introduce and develop the field of algebraic communication complexity, the theory dealing with the least number of messages to be exchanged between two players in order to compute the value of a polynomial or rational function depending on an input distributed between the two players. We define a general algebraic model over an arbitrary field k of characteristic 0, where the ...

Recently, in Phys. Rev. Lett. 95, 140601 (2005), P. Grassberger addresses the interesting issue of the applicability of q-statistics to the renowned Feigenbaum attractor. He concludes there is no genuine connection between the dynamics at the critical attractor and the generalized statistics and argues against its usefulness and correctness. Yet, several points are not in line with our current ...

In my presentation I will discuss how sociolinguistic corpora can be compiled so as to document and maximize access to the context of its collection. This is no doubt a murky issue for the coding and categorization enterprise, but it is as critical as demographic information if we are going to be able to compare data sets from different communities, eras or across research projects. However, ho...
