  • Sauer-Budge, A.M.; Huerta, A.; Bonet, J.; Peraire, Jaime (2003-01)
    We present a method for Poisson’s equation that computes guaranteed upper and lower bounds for the values of linear functional outputs of the exact weak solution of the infinite dimensional continuum problem using traditional ...
  • Xuan, Z.C.; Lee, Kwok Hong; Patera, Anthony T.; Peraire, Jaime (2004-01)
    We present an a-posteriori method for computing rigorous upper and lower bounds of the J-integral in two dimensional linear elasticity. The J-integral, which is typically expressed as a contour integral, is recast as a ...
  • Nguyen, Vinh Tan; Khoo, Boo Cheong; Peraire, Jaime (2005-01)
    The discontinuities in the solutions of systems of conservation laws are widely considered as one of the difficulties in numerical simulation. A numerical method is proposed for solving these partial differential equations ...
  • Wang, Shengyin; Tai, Kang (2004-01)
    In this study, an improved bit-array representation method for structural topology optimization using the Genetic Algorithm (GA) is proposed. The issue of representation degeneracy is fully addressed and the importance of ...
  • Strang, Gilbert (2003-01)
    My research is concentrated on applications of linear algebra in engineering, including wavelet analysis and structured matrices. This paper will appear in the book Mathematical Systems Theory (J. Rosenthal and D. Gilliam, ...
  • Jiang, Yi; Li, Le-Wei; Li, Er-Ping (2002-01)
    With the increasing demand of higher operating frequencies for electronic circuits, the printed circuit board designers face more electromagnetic radiation problems than ever. Some “rules-of-thumb” are employed to help the ...
  • Willcox, Karen E. (2002-01)
    Truely optimal solutions to system design can only be obtained if the entire system is considered. In this research we consider design of commercial aircraft, but we expand the system to include a family of planes. A ...
  • Sen, Hock Chan (2002-01)
    Automated Guided Vehicles (AGVs) are now becoming popular in container-handling applications at seaport. Efficacy of the dispatching strategy adopted to deploy AGVs is a prime factor affecting the performance of the entire ...
  • Perakis, Georgia; Sood, Anshul (2002-01)
    We present a dynamic optimization approach for perishable products in a competitive and dynamically changing market. We build a general optimization framework that ties together the competetive and the dynamic nature of ...
  • Tan, S.N.; Khoo, Boo Cheong (2003-01)
    The separating characteristics of high performance liquid chromatography (HPLC) columns, measured in terms of the height equivalent of a theoretical plate (HETP) and skewness of the eluted peak, are investigated using ...
  • Bonet, J.; Huerta, A.; Peraire, Jaime (2002-01)
    We present an implicit a-posteriori finite element procedure to compute bounds for functional outputs of finite element solutions in large strain elasticity. The method proposed relies on the existence of a potential energy ...

    In this paper, the precorrected-FFT method is used to solve the electromagnetic scattering from two-dimensional cavities of arbitrary shape. The integral equation is discretized by the method of moments and the resultant ...

    We report a Hessian-implicit optimization method to quickly solve the charge optimization problem over protein molecules: given a ligand and its complex with a receptor, determine the ligand charge distribution that minimizes ...
  • Kuo, Shihhsien; Altman, Michael D.; Bardhan, Jaydeep P.; Tidor, Bruce; White, Jacob K. (2003-01)
    Biomolecular structure and interactions in aqueous environment are determined by a complicated interplay between physical and chemical forces including solvation, electrostatics, van der Waals forces, the hydrophobic effect ...
  • Peraire, Jaime; Budge, Alexander M. (2002-01)
    We introduce a new method for computing a posteriori bounds on engineering outputs from finite element discretizations of the incompressible Stokes equations. The method results from recasting the output problem as a ...
