TL;DR: In this paper, the present state of research into Faraday effect current sensors is outlined, eight possible approaches for overcoming the problem associated with the linear birefringence inside the fibres of optical current sensors are simply introduced, recent advances in this area are reviewed, and possible prospects are considered.
Abstract: The Faraday effect is becoming widely used as an optical method of measuring electric current or magnetic field. It is particularly advantageous where the measurements must be made at high voltage or in the presence of electromagnetic interference, and where speed or stability are considerations. In this paper, the present state of research into Faraday-effect current sensors is outlined, eight possible approaches for overcoming the problem associated with the linear birefringence inside the fibres of optical current sensors are simply introduced, recent advances in this area are reviewed, and possible prospects are considered.

TL;DR: In this article, the authors used the complex function method for solving the problem of interaction of plane SH-waves and circular cavity surfaced with lining in anisotropic media, which can be used to simulate the conditions of the geology.
Abstract: In this paper, we use the complex function method for solving the problem of interaction of plane SH-waves and circular cavity surfaced with lining in anisotropic media. Anisotropic media can be used to simulate the conditions of the geology. This problem can be handled by using the method similar to that incorporated in Ref. [5] to define the scattering waves in media, added with the given boundary condition of the circular cavity.

TL;DR: In this paper, the Kane's equations for the Routh's form of variable mass nonholonomic systems are established, and a new Kane's equation for percussion motion is derived from them.
Abstract: In this paper, the Kane's equations for the Routh's form of variable mass nonholonomic systems are established, and the Kane's equations for percussion motion of variable mass holonomic and nonholonomic systems are deduced from them. Secondly, the equivalence to Lagrange's equations for percussion motion and Kane's equations is obtained, and the application of the new equation is illustrated by an example.

TL;DR: The inverse problem in calculus of variations has been attended to by many mathematicians and mechanicians, and this problem is called the inverse problem as discussed by the authors, and the importance of variational method has been tested by a lot of facts in many fields.
Abstract: Calculus of variations is a very important tool to study mechanics, physics and other else technical science. The importance of variational method has been tested by a lot of facts in many fields. But how to find a general method to convert the boundary value problem into stationary value problem, has been attended to by many mathematicians and mechanicians, and this problem is called the inverse problem in calculus of variations.
TL;DR: An improvement has been made on the algorithm of solving the kernels of new functions which are generated after a common divisor appearing in the original functions is replaced by a new intermediate variable and an efficient method based on kernel heritage is presented.
Abstract: In this paper, an improvement has been made on the algorithm of solving the kernels of new functions which are generated after a common divisor appearing in the original functions is replaced by a new intermediate variable. And an efficient method based on kernel heritage is presented. This method has been successfully used in synthesis of LCA (Logic Cell Array).
TL;DR: In this paper, an attempt to use Haralick method to evaluate manufactured wood surface roughness through the utilization of imaging processing and pattern recognition techniques through the use of the methodology presented in this paper, We can give features of wood surface by spatial dependence matrices The preliminary results indicated that the method has the advantages of noncontact, three-dimensional, high-speed This method can be used in classification and in-time measurement of manufactured wood products.
