Twochannel decentralized integralaction controller design
(IEEE, 2002)We propose a systematic controller design method that provides integralaction in linear timeinvariant twochannel decentralized control systems. Each channel of the plant is singleinputsingleoutput, with any number ... 
Twodimensional Bose condensates in a harmonic trap
(2002)We study the condensate wave function of a twodimensional Bose condensate in an harmonic trap potential using the recently proposed meanfield equation that takes into account the correct dimensionality effect. We compare ... 
Twodimensional Bose polaron using diffusion Monte Carlo method
(World Scientific Publishing, 201909)We investigate the properties of a mobile impurity immersed in a twodimensional (2D) Bose gas at zero temperature using quantum Monte Carlo (QMC) methods. The repulsive boson–boson and impurityboson interactions are ... 
Twodimensional bosonfermion mixtures
(2009)Using meanfield theory, we study the equilibrium properties of bosonfermion mixtures confined in a harmonic pancakeshaped trap at zero temperature. When the modulus of the s wave scattering lengths are comparable to ... 
Twodimensional bosonfermion mixtures in harmonic traps
(Elsevier Science B.V., 2003)The density profiles of bosonic and fermionic components in a system of trapped twodimensional (2D) bosonfermion (BF) mixture are studied. We employ the variational approach to minimize the total energy functional of the ... 
Twodimensional C / BN core / shell structures
(American Physical Society, 2011)Singlelayer coreshell structures consisting of graphene as the core and hexagonal boron nitride as the shell are studied using the firstprinciples planewave method within density functional theory. Electronic energy ... 
Twodimensional complex paritytimesymmetric photonic structures
(American Physical Society, 201502)We propose a simple realistic twodimensional complex paritytimesymmetric photonic structure that is described by a nonHermitian potential but possesses realvalued eigenvalues. The concept is developed from basic ... 
Twodimensional computational modeling of thin film evaporation
(Elsevier Masson, 2017)A considerable amount of the evaporation originates from the close vicinity the threephase contact line in an evaporating extended meniscus due to the low thermal resistance across the ultra thin film. Evaporation taking ... 
Twodimensional ferroelectric photonic crystals: Optics and band structure
(Taylor & Francis Inc., 20130920)In this report we present an investigation of the optical properties and band structure calculations for the photonic structures based on the functional materials ferroelectrics. A theoretical approach to the optical ... 
Twodimensional FIR filters
(CRC Press, 2003)In this chapter, methods of designing twodimensional (2D) finiteextent impulse response (FIR) discretetime filters are described. Twodimensional FIR filters offer the advantages of phase linearity and guaranteed ... 
Twodimensional fluorinated boron sheets: mechanical, electronic, and thermal properties
(American Chemical Society, 2018)The synthesis of atomically thin boron sheets on a silver substrate opened a new area in the field of twodimensional systems. Similar to hydrogenated and halogenated graphene, the uniform coating of borophene with fluorine ... 
Twodimensional fractional Fourier transform and its optical implementation
