‎A universal schema for diagonalization was popularized by N.S‎. ‎Yanofsky (2003)‎, ‎based on a pioneering work of F.W‎. ‎Lawvere (1969)‎, ‎in which the existence of a (diagonolized-out and contradictory) object implies the existence of a fixed-point for a certain function‎. ‎It was shown that many self-referential paradoxes and diagonally proved theorems can fit in that schema‎. ‎Here‎, ‎we fi...

Damping performs essential function in format of earthquake resistant structures, which lower the change shape when they are subjected to lateral loads or earthquake. In existing study fluid viscous dampers (FVD) used consider response RCC buildings on sloping ground. The important challenge a structure is endure and switch them foundation control story displacement. order make resistant, have ...

Artikel ini memaparkan hasil studi numerik terhadap perilaku link geser (shear link) pada sistem struktur baja tahan gempa tipe Eccentrically Braced Frame (EBF). Rangka berpengaku eksentrik (EBF) mempunyai kekakuan elastik yang sangat baik dibawah pembebanan lateral sedang dan daktilitas tinggi saat dibebani beban besar. Dibawah kondisi ekstrim inelastik direncanakan untuk ditahan oleh Link. Ki...

OBJECTIVES This study examined the effects of palate depth, modifications of the arm shape, and anchor screw placement in the mid-palatal area on rapid maxillary expansion (RME) using finite element (FE) analysis. MATERIALS AND METHODS Three-dimensional FE models were constructed that included the maxilla (cortical and cancellous bone), maxillary sinus, maxillary first molar and first premola...

This paper presents an explicit mixed finite element formulation to address compressible and quasi-incompressible problems in elasticity and plasticity. This implies that the numerical solution only involves diagonal systems of equations. The formulation uses independent and equal interpolation of displacements and strains, stabilized by variational subscales (VMS). A displacement sub-scale is ...

Extraretinal information, such as corollary discharge (CD), is hypothesized to help compensate for saccade-induced visual input disruptions. However, support for this hypothesis is largely for one-dimensional transsaccadic visual changes, with little comprehensive information on the spatial characteristics. Here we systematically mapped the two-dimensional extent of this compensation by quantif...

The objectives of this study were to obtain linearized stiffness matrices, and assess the linearity and hysteresis of the motion segments of the human lumbar spine under physiological conditions of axial preload and fluid environment. Also, the stiffness matrices were expressed in the form of an 'equivalent' structure that would give insights into the structural behavior of the spine. Mechanica...

Systems of linear differential equations with constant coefficients, as well as Lotka–Volterra equations, with delays in the off–diagonal terms are considered. Such systems are shown to be asymptotically stable for any choice of delays if and only if the matrix has a negative weakly dominant diagonal.

Abstract A new form of time-harmonic Maxwell’s equations is developed on the base standard ones and proposed for numerical modeling. It written magnetic field strength H , electric displacement D, vector potential scalar Φ. There are several attractive features this form. The 1st one that differential operator acting these quantities positive. 2nd absence curl operators among leading order oper...

Abstract Buildings with different roofing systems possess seismic performance during earthquake. Most of the traditional buildings are susceptible to earthquake disaster due no loading is considered in design. In addition, irregular have been proven perform badly events. Due lack investigations on asymmetrical timber-concrete hybrid building under loading, a ¼ this type model was tested seismic...
