Computer-based Creativity Enh.nced Conceptual Design Model for Non-routine Design of Mech.nical Systems

Ch.nese Journal of Mech.nical Engineering 2014年第6期27卷 1083-1098页

作者： LI Yutong WANG Yuxin DUFFY Alex h.B Department of Mech.nical & Electrical Engineering China University of Petroleum Design Manufacture and Engineering ManagementUniversity of Strathclyde

Computer-based conceptual design for routine design h.s made great strides, yet non-routine design h.s not been given due attention, and it is still poorly automated. Considering th.t th. function-beh.vior-structure（FBS） model is widely used for modeling th. conceptual design process, a computer-based creativity enh.nced conceptual design model（CECD） for non-routine design of mech.nical systems is presented. In th. model, th. leaf functions in th. FBS model are decomposed into and represented with.fine-grain basic operation actions（BOA）, and th. corresponding BOA set in th. function domain is th.n constructed. Ch.osing building blocks from th. database, and expressing th.ir multiple functions with.BOAs, th. BOA set in th. structure domain is formed. Th.ough.rule-based dynamic partition of th. BOA set in th. function domain, many variants of regenerated functional sch.mes are generated. For enh.ncing th. capability to introduce new design variables into th. conceptual design process, and dig out more innovative ph.sical structure sch.mes, th. indirect function-structure match.ng strategy based on reconstructing th. combined structure sch.mes is adopted. By adjusting th. tigh.ness of th. partition rules and th. granularity of th. divided BOA subsets, and making full use of th. main function and secondary functions of each.basic structure in th. process of reconstructing of th. ph.sical structures, new design variables and variants are introduced into th. ph.sical structure sch.me reconstructing process, and a great number of simpler ph.sical structure sch.mes to accomplish.th. overall function organically are figured out. Th. creativity enh.nced conceptual design model presented h.s a dominant capability in introducing new deign variables in function domain and digging out simpler ph.sical structures to accomplish.th. overall function, th.refore it can be utilized to solve non-routine conceptual design problem.

Natural Science 2012年第12期4卷 1042-1055页

作者： Edwin h. Kaufman Jr Corey R. Page Casey R. Watson Department of Math.matics Central Michigan University Mount Pleasant USA Department of Mech.nics Materials and Aerospace Engineering Illinois Institute of Technology Chicago USA Department of Ph.sics and Astronomy Millikin University Decatur USA

In th.s paper we introduce meth.ds for approximating local standard time in th. North.rn h.misph.re using Polaris and th. Big Dipper as well as alternative reference stars, and describe in detail h.w to construct a device we call a dipperclock to facilitate th.s process. An alternative meth.d wh.ch.does not require a dipperclock is also discussed. Ways of constructing dipperclocks wh.ch.glow in th. dark are presented. Th. accuracy of dipperclocks is examined, both.th.oretically and th.ough.field testing. A java program is provided for creating dipperclocks customized to a particular year-long time period and place to get improved accuracy. Basic astronomical definitions and justifications of th. results are provided. We also discuss th. use of dipperclocks to find longitude and latitude.

Computer Tech.ology and Application 2012年第4期3卷 305-314页

作者： Timoth. W. O"Neil Dale h. Mugler Kath. J. Liszka Department of Computer Science The University of Akron Departments of Biomedical Engineering and Math.matics The University of Akron

Th. Fourier transform is very important to numerous applications in science and engineering. h.wever, its usefulness is h.mpered by its computational expense. In th.s paper, in an attempt to develop a faster meth.d for computing Fourier transforms, th. auth.rs present parallel implementations of two new algorith.s developed for th. type IV Discrete Cosine Transform （DCT-IV） wh.ch.support th. new interleaved fast Fourier transform meth.d. Th. auth.rs discuss th. realizations of th.ir implementations using two paradigms. Th. first involved commodity equipment and th. Message-Passing Interface （MPI） library. Th. second utilized th. RapidMind development platform and th. Cell Broadband Engine （BE） processor. Th.se experiments indicate th.t th. auth.rs＇ rotation-based algorith. is preferable to th.ir lifting-based algorith. on th. platforms tested, with.increased efficiency demonstrated by th.ir MPI implementation for large data sets. Finally, th. auth.rs outline future work by discussing an arch.tecture-oriented meth.d for computing DCT-IVs wh.ch.promises furth.r optimization. Th. results indicate a promising fresh.direction in th. search.for efficient ways to compute Fourier transforms.

Magnetic Field Intensity/Melatonin-Molarity Interactions: Experimental Support with.Planarian (Dugesia sp.) Activity for a Resonance-Like Process

引用

Open Journal of Bioph.sics 2012年第4期2卷 137-143页

作者： Bryce P. Mulligan Noa Gang Glenn h. Parker Mich.el A. Persinger Department of Biology Behavioural Neuroscience Program Department of Biology Behavioural Neuroscience Program Biomolecular Sciences Program Laurentian UniversitySudbury Canada Department of Biology Behavioural Neuroscience ProgramBiomolecular Sciences Program Laurentian UniversitySudbury Canada

Synergistic interactions between specific magnetic field intensities and ch.mical concentrations are ch.llenging bioph.sical ph.nomena. Planarian were exposed to one of five different concentrations of melatonin and to a “geomagnetic”—patterned 7 h. amplitude modulated magnetic field for 6 min once per h.ur for 8 h. during six successive nigh.s. Th. peak average strength. were with.n th. range (50 nT) or outside th. range (200 nT) derived by th. equation. As predicted by a resonance equation planarian displayed h.gh.y statistically significant decreased relative activity with.n th. 50 nT, 10–7 to 10–6 M melatonin conditions compared to lower or h.gh.r concentrations. Th. effect explained about 30% of th. variance in th.se ch.nges of activity. Activity of planarian exposed to th. same melatonin concentrations but to th. 200 nT field did not differ significantly from each.oth.r or from th.se exposed to th. 50 nT field in concentrations of melatonin –7 M or >10–6 M. Th.se results suggest th. existence of non-linear, “narrow-band” mech.nisms involving th. numbers of molecules with.n a distance determined by th. boundary of th. organism and th. intensity of naturally-patterned magnetic fields derived from energy rath.r th.n force-based resonances.

Effect of Ambient UV-B on Stomatal Density, Conductance and Isotope Discrimination in Four Field Grown Soybean [<i>Glycine max</i>(L.) Merr.] Isolines

引用

American Journal of Plant Sciences 2013年第12期4卷 100-108页

作者： Dennis C. Gitz III Steven J. Britz Joseph.h. Sullivan Department of PLSA College of Agriculture and Natural Resources University of Maryland College Park USA USDA-ARS# Cropping Systems Research Laboratory Lubbock USA USDA-ARS Food Components and Health Laboratory Beltsville USA

An experiment was designed to test wh.th.r ambient levels of UV-B radiation affect stomatal development, decrease stomatal density, and lead to increased water-use efficiency (WUE). Soybean [Glycine max (L.) Merr.] isolines with.different stomatal distribution and flavonol expression patterns were field grown under sh.lters th.t eith.r transmitted or blocked solar UV-B. All isolines exposed to solar UV-B accumulated h.gh.r concentrations of UV-screening ph.nolic pigments but oth.r responses were isoline dependent. Solar UV-B decreased stomatal density and conductance in isolines expressing a unique branch.d kaempferol triglycoside. Decreased stomatal density was associated with.increased season-long WUE and decreased internal CO2 concentration of leaf (estimated by δ13C discrimination). We concluded th.t ph.tomorph.genic responses to UV-B affected stomatal density and WUE in field grown soybean;but th.t th. magnitude and direction of th.se response were associated with.isogenic pleiotropic differences in stomatal distribution and pigment expression. UV-B radiation h.d no effect on biomass accumulation or yield in a cultivar expressing only trace levels of kaempferol suggesting th.t flavonol expression is not prerequisite to UV-B tolerance.
