Language Engineering in Grammatical Framework (GF)
No full textThis thesis describes a number of practical experiments rather than theoreticalinvestigations in the area of natural language processing. The basis forthe work presented is Grammatical Framework (GF). It is a very complexsystem, which comprises among other things a grammar formalism based ontype theory and its implementation written in Haskell. GF is intended forhigh-quality machine translation (of INTERLINGUA type) in the restrictedlanguage domains.The primary concern of this thesis is however limited to the usage of GFas a piece of software. The main results are: Implementing a syntax editor, which provides a graphical user interface(GUI) for the command-line GF core. Writing a part of code for automatic generation of gramletspure Javaprograms with limited (compared to GF) functionality that can be runon PDA (Portable Device Assistants) and as applets in a browser. Writing the Russian resource grammar that takes care of the most basicmorphological and syntactic rules and serves as a standard libraryfor building application grammars (describing restricted language domains)in Russian.These results contribute to language engineering in GF on two differentlevels: Author level (end-user) constructing sentences in natural languages. Grammarian level building a grammar description, which is laterused on the author level.The last part of the thesis deals with a non-linguistic domain. In thatexperiment we try to apply functional parsing technique to the well-knownproblem of protein secondary structure prediction (bioinformatics)

Language Engineering in Grammatial Framework (GF)
No full textThe basis for the work presented is Grammatical Framework (GF)a grammar
formalism based on type theory. It is also a powerful language processor
that provides a convenient framework for various multilingual applications.
The primary concern of this thesis is the usage of GF as a piece of software.
The main results are:
Implementing a syntax editor, which provides a graphical user interface
(GUI) for the command-line GF core.
Writing the Russian resource grammar that takes care of the most
basic morphological and syntactic rules and serves as a standard library
for building application grammars (describing sublanguage domains) in
Russian.
These results contribute to language engineering in GF on two different
levels:
Author level (end-user)constructing documents in natural languages.
Grammarian level building a grammar description, which is later
used on the author level. One can also distinguish between application
and resource grammars. An application grammar focuses of a particular
sub-language domain, while resource grammar is a general-purpose
grammar that forms a basis for application grammars

Linear complexity profile of sequences over the field GF(Q)
No full textSummary form only given. The author extends Reuppel's concept of the linear complexity profile of binary sequences to sequences over an arbitrary finite field and provides formulas for the expected linear complexity and its variance of sequences Sn of length n over GF(q). He shows that the variance approaches 1/q when q approaches ∞. He presents criteria that could be useful when using the linear complexity profile for investigating the randomness of sequences over GF(q). Finally, the author investigates how useful these criteria are by comparing the results with other randomness tests

Investigation of the 68Zn(p,2p)67Cu nuclear reaction: new measurements up to 40 MeV and compilation up to 100 MeV
No full textSzelecsényi, F; Steyn, G.F; Dolley, S.G; Kovács, Z; Vermeulen, C; van der Walt, T.N; (2009). Investigation of the 68Zn(p,2p)67Cu nuclear reaction: New measurements up to 40 MeV and compilation up to 100 MeV. Nuclear Instruments and Methods in Physics Research B 267 (2009) 1877–1881, DOI:10.1016/j.nimb.2009.03.097The excitation function was measured for the 68Zn(p,2p)67Cu nuclear reaction from its threshold energy up to 40 MeV. Nine pieces of highly enriched 68Zn (>98%) metal foils were irradiated to obtain reliable crosssections using the usual stacked-foil technique. All foils were subjected to high efficiency radiochemical separation before the activity measurements. A critical compilation of the available experimental crosssection
results was also performed. Thick target yields of 67Cu and the longer-lived copper radio-contaminants (61Cu and 64Cu) were calculated using the reliable literature results up to 100 MeV. Additionally, EOB (End Of Bombardment) contamination levels as a function of bombarding energy and irradiation time were deduced

A systolic exponentiator for finite fields GF(2m)
No full text[[abstract]]© 1992 Institute of Electrical and Electronics Engineers - The author presents a novel parallel-in-parallel-out bit-level systolic array with unidirectional data flow for computing exponentiation in GF(2m). The array is highly regular and modular, and thus well it is suited to VLSI implementation. In addition, it can provide the maximum throughput in the sense of producing new results at a rate of one per clock cycle. Compared to a previously known systolic (GF2m) exponentiator with the same throughput performance, the proposed system requires much less chip area, has smaller latency, and makes it easier to incorporate fault-tolerant design[[department]]電機工程學
