This paper presents the algorithm on the compensator design for eliminating the nonlinearity in the capacitive pick-off MEMS open-loop accelerometer and its implementation in the FPGA. A simple and elegant method is presented for the purpose. In the sensor model of compensator, upto 3rd order terms are taken. The first step approximation is derived using linear model. This approximation is improved over iterations to reduce the non-linearity. With this method, the inertial navigational grade

displays the data with XY graph by calling the LabVIEW program. The program can get center wavelength values at the same time then get temperature by fitting function and display temperature on the front panel of the program. The fitting line of linearity between center wavelength of optical fiber Bragg grating sensor and temperature is above 0.95. The function reveals a good linearity which fitting the wavelength changes of the optical fiber Bragg grating during this temperature range. The

There are many sample surveys of populations that contain outliers (extreme values). This is especially true in business, agricultural, household and medicine surveys. Outliers can have a large distorting influence on classical statistical methods that are optimal under the assumption of normality or linearity. As a result, the presence of extreme observations may adversely affect estimation, especially when it is carried out at a low level of aggregation. To deal with this problem, several

A parametric analysis is accomplished to determine the influence of the thickness of the base steel and the covering ebonite layer on the perimeter change of the outer surface, taking into account the physical non-linearity of the outer layer.

The accelerometers used for Inertial Navigation in satellite launch vehicles demand excellent performance in terms of sensitivity, noise immunity, linearity, bias and scale factor stability over time and environmental changes. Detailed and in-depth design of the microstructure by computer simulation is required to ensure structural integrity and reliability of the microstructure. The microstructure of the accelerometer consists of a proof mass suspended from the mounting frame by beam springs

Moreover, the use of nanostructured materials allows for the development of a new generation of modern printed circuit antennas and will enable wide range of applications merging both technologies for a wide range of wearable and implantable sensing devices.

The model based on partial least squares regression and neural network can identify stator resistance under different conditions of the motorized spindle. The results show that the method has high identification precision and is helpful to improve the performance of vector control system.

using the Layer-by-Layer (LbL) technique. The refractive index of this polymeric coating is sensitive to changes in the external relative humidity (RH), which permits the fabrication of humidity sensors based on LMRs.The wavelength based fabricated sensors showed a dynamical range of 65 nm when the RH varied in the range from 20 to 80% and it has a good linearity when the RH is higher than 40%, high stability and are highly reproducible.
