Upscaling measurements from ground-based sites or underway monitoring to a regional or global scale provides important information to policy makers for environmental management and to researchers looking for a better understanding of relevant issues. We used the reconstruction of global surface ocean CO2 as an example to evaluate the performance of four machine learning models: Random Forest (RF), Support Vector Machine (SVM), Feedforward Neural Network (FNN), and Self-Organization Map (SOM). The results show the performance from high to low as RF, SVM, FNN, and SOM. However, the overall differences of modelled CO2 among the four models are insignificant. Considering the discrete characteristics of RF, it is recommended to use SVM or FNN when the number of data point is not large and continuous estimations are expected. RF has an advantage particularly when the number of data points is very large and the data include categorial variables.

A novel design for degrading or decreasing the system performance due to the spatially channel correlated phenomenon by using of the artificial intelligence (AI) will be proposed in this project. Based on the AI the deep learning algorithms will be applied to solve the problems mentioned above. Frequently, the issues of correlated channel are solved by applying the data scrambling over forward link and avoiding the intersymbol interference (ISI) repeatedly, respectively. It is predicated that there will meet many challenges in the way to establish the 3-D correlated channel model. The beamforming technology used in the antenna pattern can be adopted to collect the data for feeding to the input of deep learning. The simulation and analyzed results will compare to the one that obtains from the traditional MIMO radio systems with correlated channels. The system performance is going to be optimized by the work out for the 3-D massive-MIMO communication in order to decrease the degradation of spatially correlated channel.

Smart manufacturing systems (SMSs), are proposed in the era of Industry 4.0 and Industry Internet of Things, supported by the Cyber Physical Systems (CPS), Artificial Intelligent (AI), and smart sensing and cognitive technologies, as an autonomous system to better solve the problems such as personalized customization, quick response, and sustainable value added. However, existing analysis and design approaches use a narrower concept, which focuses on either knowledge, business or service aspects, neglecting to consider the stakeholders' value. In this paper, the framework of smart manufacturing systems based on the sustainable added value of stakeholders is presented. It has been suggested that reflecting upon stakeholders’ value may bring a better understanding of analyzing the SMSs paradigms.

This paper presents a development of a mid-infrared laser expected to be used as sensor light source for precision engineering measurement. A ring oscillator based on nonlinear polarization rotation with erbium-doped-fluoride fiber was developed. Laser oscillation at the wavelength of $2.8, mu mathrm {m}$ was obtained with pumping the fluoride fiber by a diode laser at the wavelength of 976 nm. A spectrometer was also developed for real-time measurement of spectra of the laser oscillation. As a result of observing a spectrum, only continuous wave oscillation was gained.

In this paper, 300 V circular nLDMOS DUTs is used as the experimental benchmark group, and a smart architecture of HVPW is added into the HVNW drift-region to form a super-junction (SJ) structure (radial-type SJ). And then, for the HVPW/HVNW area modulation of radial-type SJ, three different kinds of area ratios is fabricated. However, the HBM capacity of this nLDMOS reference group has only 2500V. Furthermore, as for the radial-type SJ and HVPW/HVNW with different proportions of area modulation in the drift region, it has the highest HBM-immunity capacity of 7000V when the HVPW/HVNW area ratio of 2 to 1. That is to say, in the SJ architecture, the higher the proportion of HVPW/HVNW, the stronger its ESD immunity reliability.

Based on MVS-SfM algorithm, the commercial image processing software PhotoScan provides the function of automatic matching of ground marks, such as, circular, square and coded mark. However, the practical plane accuracy between the auto-matching and man-selected is not well-defined. This study is compared the plane accuracy for three types of ground marks under the same variable conditions using practical UAS photogrammetry. When the image processing with three auto-matching marks are examined as well as the wing mark is also used the man-selected to put together to compare the plane accuracy. Overall, the plane accuracy of man-selected wing mark is better than three auto-matching marks in the orthophoto. Meanwhile, the plane accuracy using square mark is better than the rest marks in three auto-matching process. The obtained accuracy result is much close to man-selected wing mark. It is recommended that choosing the auto-matching square mark can be derived the better performance in practical project implementation.

Geometric errors of machine tools are one of the main contributors for machining inaccuracies. A multi-step error measurement and compensation method is proposed in this paper to investigate the effects of different geometric errors on volumetric errors. The kinematic error chain is built using multi-body system theory (MBS) and homogenous transformation matrices first. Then, the original geometric errors without any compensations are measured and the deviations of tool tip caused by different geometric errors are calculated. Furthermore, various compensation strategies considering diverse geometric errors effects are carried out in the machine tool to validate the predicted volumetric errors. The multi axis calibrator, which can detect six errors of a translational axis in one measurement, is used to measure the variations of 18 errors of translational axes and volumetric diagonal errors of a three axes machine tool. Besides, the squareness errors were measured by a ball-bar. The pragmatic effects of positioning, straightness, angular and squareness errors on volumetric errors are derived from comparisons between various compensation results. Results reveal that linear errors effect the whole volumetric positioning errors while the angular errors mainly effect the volumetric positioning errors of the region far from reference coordinate point.
