The mechanical nonlinearity of a masonry structure depends on debonding and slip joints the fracture blocks like bricks concrete. present study proposes behavioral simulation to idealize by allocating three orthogonal planes, which are governed existing multi-directional crack model, represent damage using another planes. shear stiffness joint changes due disintegration infilling mortar caused ...

In this paper, we define the β-partial derivative as well β-directional of a multi-variable function based on β-difference operator, Dβ, which is defined by Dβf(t)=f(β(t))−f(t)/β(t)−t, where β strictly increasing continuous function. Some properties are proved. Furthermore, β-gradient vector and directional introduced. Finally, deduce Hahn-partial Hahn-directional derivatives associated with Ha...

The limit equilibrium method (LEM) has been a main-stay of analysis for geotechnical engineers for decades. Applied typically in a 2-D plane strain condition the method has been extended in formulation to the method of columns in 3-D and is now gaining increased use in industry. The formulation of the 3-D method of columns has typically been presented in Cartesian coordinates and with the assum...

Abstract In this paper, we propose a multi direction color interpolation method for multiple channel images. The proposed gradient judgment method silences the mediocre color interpolation artifacts. We adopted various weights from different directional gradients for conducting adaptive directional interpolation. The proposed weights are computed using correlation and intensity differences. The...

This work presents an audio beam loudspeaker that possesses the capability of emitting multiple audio beams into different directions at the same time. Ultrasonic loudspeakers applying parametric array technology are used to generate highly directional audible sound beams. The loudspeaker itself appears as a single device and can be mounted under the ceiling of a room in order to supply selecte...

This paper presents a discrete generalized multi-directional Radon transform (GMDRT) and its exact inversion algorithm. GMDRT is an extension of the classical Radon transform. It aims to project parameterized curves and geometric objects following several directions. For this purpose, we propose an algebraic formalism of the Radon Transform presenting the forward transform as a matrix-vector_ m...

New application areas for database technology such as computer-aided design and analysis systems require a semantically rich data model, high performance, extensibility, and application oriented queries. We have built a system for finite element analysis using a functional database management system to represent multiple matrix representations. The functional data model is well suited for manag...
