    Symbolic energy estimation model with optimum start algorithm implementation

    No full text
    The drive to reduce carbon emissions and energy utilisation, directly associated with dwellings and to achieve a zero carbon home, suggests that the assessment of energy ratings will have an increasingly prioritised role in the built environment. Created by the Building Research Establishment (BRE), the Standard Assessment Procedure (SAP) is the UK Government’s recommended method of assessing the energy ratings of dwellings. This paper describes a new, simplified dynamic method (hence known as IDEAS – Inverse Dynamics based Energy Analysis and Simulation) of assessing the controllability of a building and its servicing systems. The IDEAS method produces results that are comparable to SAP. An Optimum Start algorithm is explored in this paper to allow heating systems of different responsiveness and size to be integrated into the IDEAS framework. Results suggest that this design approach could enhance the SAP Methodology by the addition of advanced systems controllability and dynamic values

    Benchmarking the effect of weather data upon energy estimation of UK homes

    This paper extends a fundamental dynamic method of assessing the controllability of a building and its servicing systems: IDEAS – Inverse Dynamics based Energy Assessment and Simulation. IDEAS produces results which are calibrated with the UK Government’s Standard Assessment Procedure (SAP). The extension presented is a measure of the effect upon energy estimation by varying climactic data, using CIBSE TRY/DSY weather data for 14 locations across the UK. A calibrated standard test case dwelling is initially modelled in IDEAS and SAP. Using each of the CIBSE weather locations, the variation in energy estimation of the standard test case dwelling is analysed. Results suggest that use of localised weather data can have a noteworthy effect on energy estimation and can play an important role on delivering buildings which are truly fit for purpose

    Language Engineering in Grammatical Framework (GF)

    No full text
    This 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)

    The 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 text
    Summary 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

    [[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
