This study investigates how useful the PIXE technique is in the analysis of complex matrix composition in earth materials. Hence it gives an information on PIXE in relation to other nuclear techniques. Results obtained by PIXE must be compared with other complementary techniques to obtain an overall elemental analysis of the matrix composition of high-grade earth materials. Finally, the results are reviewed.

The Capon method serves as a powerful and robust data analysis tool when working on various kinds of ill-posed inverse problems. Besides the analysis of waves, the method can be used in a generalized way to compare actual measurements with theoretical models, such as Mercury's magnetic field analysis. In view to the BepiColombo mission this work establishes a mathematical basis for the application of Capon's method to analyze Mercury's internal magnetic field in a robust and manageable way.

The aerosol optical depth is a parameter widely used in remote sensing for the characterization of the atmospheric aerosol particles. The AERONET network was created by NASA for aerosol monitoring, satellite and model validation. The University of Valladolid manages since 2006 a calibration center of AERONET. The CÆLIS software tool, developed by UVa, was created to manage the data generated by the AERONET photometers. The AOD algorithm in CÆLIS is developed and validated in this work.

The baseline wander has special characteristics, such as low frequency, large amplitude, non-periodic and non-stationary. This phenomenon is causes by the receiving coil motion and always exists in the process of data acquisition. The proposed method can be used to solve similar problem. This paper has the following highlights: 1. The method can be used to process non-periodic and non-stationary signal. 2. The method own adaptive to satisfy stopping criterion based on measured signal.

At present, indoor positioning technology is used in all aspects of life. I study the positioning method of UWB radar network. Because of the interference in the indoor environment, the UWB radar measurement data produce abnormal values. In order to eliminate the outliers, the method of fitting the known true value with the actual measured value is used to obtain the linear relationship between the true value and the measured value, so as to get the unknown true value through the measured value.

Bidirectinal muographic measurements were conducted at the ancient burial mound built in the beginning of the 6th century and later collapsed after a landslide caused by the 1596 Fushimi Earthquake, one of the largest earthquakes over last few centuries in Japan. The result indicated large-scale vertical cracks at the top of the mound, which caused its collapse and thus, an intrinsic problem was suggested with the stability of the basic foundation of the mound before this earthquake.

In this paper, a low-cost, computer-aided and geophone-based system designed to record, monitor and analyze the three-component microtremor data, is presented. This system has several features such as 200 Hz sampling frequency, text data format and data analysis tools. The developed software undertakes many tasks such as communication between the external hardware and computer, transferring, monitoring and recording the seismic data to computer, and interpretation of the recorded data.

One of the four Galilean moons of Jupiter, Europa, is one of the most promising places in the solar system to find life outside Earth. For this reason, the space science community is currently focused on exploring it. One of the main difficulties of such task is the harsh radiation environment, caused by the radiation belts of Jupiter. In this paper we present results for a magnetic fields sensor being exposed to radiation levels similar to those expected at the surface of Europa.

We propose a gradiometer based technique to clean multi-sensor magnetic field data acquired onboard spacecraft. The technique takes advantage on the fact that the maximum variance direction of many AC disturbances onboard spacecraft does not change in time. We apply the proposed technique to the SOSMAG instrument onboard GeoKompsat-2A. We analyse the performance and limitations of the technique and discuss in detail how various disturbances are removed.
