(Professional Engineering Publishing / SAGE Publications Ltd, 2010)This paper presents the equations of motion for a general articulated road vehicle, with variable numbers of wheels for the tractor and trailer. The equations are applicable to vehicle-bridge dynamic interaction problems ...

(Inderscience Enterprises, 2010-04-24)A new evolutionary design tool is presented, which uses shape grammars and a grammar-based form of evolutionary computation, grammatical evolution (GE). Shape grammars allow the user to specify possible forms, and GE allows ...

Synergistic effects on band gap-narrowing in titania by codoping from first-principles calculations (ACS Publications, 2010-02-12)The large intrinsic band gap in TiO2 has hindered severely its potential application for visible-light irradiation. In this study, we have used a passivated approach to modify the band edges of anatase-TiO2 by codoping of ...

(Elsevier, 2010-02-15)The large intrinsic band gap of NiO has hindered severely its potential application under visible-light irradiation. In this study, we have performed first-principles calculations on the electronic properties of N- and ...

(Taylor and Francis, 2010-06)The structural and electronic properties of rutile and anatase, and the influence of both mono- and co-doping, have been studied using Density Functional Theory. Ge-doped anatase and rutile exhibit different band gap-narrowing ...

(SPIE, 2010-04-13)At present there is a global concern of environmental issues and future energy supplies, for instance global warming and the rapid depletion of fossil fuels. This trepidation has initiated a more critical investigation ...
-
(Wiley, 2010-12)Aims: The purpose of this study was to develop a system that would allow biofilms to be cultivated under strictly defined conditions in terms of dissolved oxygen, fluid shear and to assess whether the method was suitable ...

(American Chemical Society, 2010-08-19)The origin of the experimentally observed band gap narrowing and red-shift of the adsorption edge of cubic In2O3 induced by C doping has been investigated using density functional theory calculations. We have compared the ...
-
(Elsevier, 2010-10-08)The energetic and electronic properties of F and/or Zr-doped anatase TiO2 are investigated by first-principles calculations. For F-doping, reduced Ti3+ ions are formed and Ti orbitals lie slightly below the conduction band, ...
-
(Wiley, 2010-08-23)The energetic and electronic structures of V-doped anatase TiO2 have been investigated systematically by the GGA+U approach, including replacement of Ti by V in the absence and presence of oxygen vacancies and the presence ...
