B and H sensors for 3-D magnetic property testing

Robust 3 D Surface Property

Estimation of local surface geometry (i.e. principle frame and principle quadric) is discussed. It is shown that surface tting methods are more robust that-nite diierence based approaches for a number of reasons. The local surface geometry is used to segment the surfaces into regions corresponding to smooth patches, separated by visibility boundaries, occluding contours, and ridges. Points with...

Generalized Frames for B(H, K)

Frames play significant role in various areas of science and engineering. Motivated by the work of Chander Shekhar, S. K. Kaushik and Abas Askarizadeh, Mohammad Ali Dehghan, we introduce the concepts of $K$-frames for $B(mathcal{H, K})$ and  we establish some result. Also, we consider the relationships between $K$-Frames and $K$-Operator Frames for $B(mathcal{H})$.

A new method for 3-D magnetic data inversion with physical bound

Inversion of magnetic data is an important step towards interpretation of the practical data. Smooth inversion is a common technique for the inversion of data. Physical bound constraint can improve the solution to the magnetic inverse problem. However, how to introduce the bound constraint into the inversion procedure is important. Imposing bound constraint makes the magnetic data inversion a n...

Finding the Optimal Place of Sensors for a 3-D Damped Wave Equation by using Measure Approach

In this paper‎, ‎we model and solve the problem of optimal shaping and placing to put sensors for a 3-D wave equation with constant damping in a bounded open connected subset‎ ‎of 3-dimensional space‎. ‎The place of sensor is modeled by a subdomain‎ ‎of this region of a given measure‎. ‎By using an approach based on the embedding process‎, ‎first‎, ‎the system is formulated in variational form;...
