Olefin cross metathesis and ring-closing metathesis in polymer chemistry

The use of olefin cross metathesis in preparing functional polymers, through either pre-functionalisation of monomers or post-polymerisation functionalisation is growing in both scope and breadth. The broad functional group tolerance of olefin metathesis offers a wealth of opportunities for introducing a broad range of functional groups into the polymer backbone, tuning polymer properties and expanding potential applications. Similarly, ring-closing metathesis offers the ability to tune the polymer macrostructure and microstructure to similar effect. In this review, we explore the importance of understanding selectivity in olefin cross metathesis in designing functional polymers, the manipulation of this reactivity to prepare (multi)functional polymers, and show how polymer systems can be constructed to favour ring closing and change backbone structure and properties

An information theoretic approach to natural language processing.

A new method of natural language processing, based on the theory of information is described. Parsing of a sentence is accomplished not in a sequential manner, but in a fashion that begins by searching for the main verb of the sentence, then for the object, subject and perhaps for a prepositional phrase. As each new part of speech is located, the uncertainty of the sentence's meaning is reduced. When the uncertainty reaches zero, the parsing is complete, and the machine performs the task assigned by the input sentence. The process is modeled by a Markov Chain, which can often be used for the internal representation of the sentence. All of this work is done for communication with an intelligent task oriented machine, but the theoretical basis for extending this to other, more complicated domains is also described. A description of a methodology for extending the theory, so that it can be used for the implementation of a machine that learns is also described in this paper. By using belief networks, the machine constructs additions to its basic Markov Chain in order to handle new verbs and objects, which were not included in the original programming. Once implemented, the system will then treat the new word as if it had originally been programmed into the machine. Finally, several prototypes are described which have been written to validate the theory presented. The information theoretic system contained herein is compared to other techniques of natural language processing, and shown to have significant advantages

A PROGRAM TO DISPLAY BIG DATA

This paper describes a new way to look at telemetry data. We examine a way to use virtual reality to evaluate and view data from a large collection of stored signals. Each individual signal will have limits associated with it that allow us to determine whether any part of the signal exceeds those limits and if so what part(s) of the waveform contain these abnormalities. A program using virtual reality to illustrate the technique has been written and will be demonstrated as part of the conference presentation.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.

A Program to Display Big Data

ITC/USA 2014 Conference Proceedings / The Fiftieth Annual International Telemetering Conference and Technical Exhibition / October 20-23, 2014 / Town and Country Resort & Convention Center, San Diego, CAThis paper describes a new way to look at telemetry data. We examine a way to use virtual or also augmented reality to evaluate and view data from a large collection of stored signals. Each individual signal will have limits associated with it that allow us to determine whether any part of the signal exceeds those limits and if so what part(s) of the waveform contain these abnormalities.
