With the development of society, digital signal processing technology has been widely used by more and more people to various industries. It is to promote our entire world of information technology development is very favorable, and it can also be the maximum to help people improve the efficiency of working life, so the need to further strengthen its research. In the present situation, digital signal processing technology is the use of electronic equipment to carry out the measurement of the important components of the work, so in the future development process, the need to continue to strengthen the application of digital signal technology for human production and life to provide more the convenience. Based on this paper, the application of digital signal processing technology in the field of electronic measuring instruments is analyzed.

The displacement damage dose methodology for analysing and modelling the performance of triple-junction InGaP 2 /GaAs/Ge solar cells in an electron radiation environment is presented. Degradations at different electron energies are correlated with displacement damage dose (D d ). One particular electron radiation environment, relative to a geosynchronous earth orbit (GEO), is chosen to calculate the total D d behind the different thicknesses coverglasses to predict the performance degradation at the end of the 15-year mission.

PREPARED, Enabling Change, is an EU-funded Collaborative Project under the Seventh Framework Programme (FP7). The project aims to gather urban utilities in Europe and worldwide to develop an advanced strategy in meeting the upcoming challenges for water supply and wastewater treatment brought by climate change. This work aims to increase technological capacity and improve performance of traditional water supply and wastewater treatment systems via better use of sensors. For newly developed multivariate sensors, calibration procedures are quite different from manufacturer to manufacturer. Manual operation during calibration and verification is commonly practised in this field due to complexity of the calibration procedure and occurrence of unpredictable events. In addition, many of the sensor manufacturers have not developed detailed instructions for sensor calibration. Therefore, a calibration and verification protocol is needed to guide and unify practice in this area where diversified practice is commonly observed. In this work, a unified protocol for sensor calibration and verification was developed and applied. Two sensor products, an optical sensor and an electronic nose sensor, are discussed as examples for calibration procedures, regression methods and verification methods of calibration in the application of wastewater treatment plant monitoring.

Objectives: Analyzing the influence of different filling methods on the microleakage of posterior teeth during the treatment of bulk resin filling. Methods:  From January 2019 to January 2020, 68 patients with posterior tooth filling (123 teeth) in our hospital were selected and randomly assigned into three groups (A, B, and C), with 41 teeth in each group. Group A received bulk posterior teeth filling resin treatment, group B received Charisma® resin filling treatment and group C received FX-? filling treatment. The curative effect and microleakage of posterior teeth between the groups were compared. Results: Comparison of treatment efficiency in group A (97.56%), group B (85.37%) and group C (73.17%) shows that P?0.05?comparison of microleakage value and operation time of group A, group B and group C shows that P?0.05. Conclusions: In resin filling treatment, bulk posterior tooth filling resin material should be selected for its high hardness, strong edge adhesion, and natural effects.
