Rainfall Algorithms Using Oceanic Satellite Observations from MWHS-2

Advances in Atmospheric Sciences 2021年第8期38卷 1367-1378页

This paper describes three algorithms for retrieving precipitation over oceans from brightness temperatures (TBs) of the Micro-Wave Humidity Sounder-2 (MHWS-2) onboard Fengyun-3C (FY-3C). For algorithm development, scattering- induced TB depressions (ΔTBs) of MWHS-2 at channels between 89 and 190 GHz were collocated to rain rates derived from measurements of the Global Precipitation Measurement’s Dual-frequency Precipitation Radar (DPR) for the year 2017. ΔTBs were calculated by subtracting simulated cloud-free TBs from bias-corrected observed TBs for each channel. These ΔTBs were then related to rain rates from DPR using (1) multilinear regression (MLR);the other two algorithms, (2) range searches (RS) and (3) nearest neighbor searches (NNS), are based on k-dimensional trees. While all three algorithms produce instantaneous rain rates, the RS algorithm also provides the probability of precipitation and can be understood in a Bayesian framework. Different combinations of MWHS-2 channels were evaluated using MLR and results suggest that adding 118 GHz improves retrieval performance. The optimal combination of channels excludes high-peaking channels but includes 118 GHz channels peaking in the mid and high troposphere. MWHS-2 observations from another year were used for validation purposes. The annual mean 2.5° × 2.5° gridded rain rates from the three algorithms are consistent with those from the Global Precipitation Climatology Project (GPCP) and DPR. Their correlation coefficients with GPCP are 0.96 and their biases are less than 5%. The correlation coefficients with DPR are slightly lower and the maximum bias is ~8%, partly due to the lower sampling density of DPR compared to that of MWHS-2.

Constraint-Guided Methods with Evolutionary Algorithm for the Automatic Test Task Scheduling Problem

引用

Chinese Journal of Electronics 2014年第3期23卷 616-620页

作者： LU Hui NIU ruiyao School of Electronic Information and Engineering Beihang University

The automatic test task scheduling problem is a key challenge for automatic test system to improve throughput and reduce test time. The constrained Test task scheduling problem(TTSP) contains network precedence constraint relationships between tasks. Constrained optimization and topological sorting are applied to handle the constraints. A chaotic non-dominated sorting genetic algorithm is used to stress exploitation ability and obtain high quality solutions. For two commonly applied realworld instances, comparisons show that topological sorting performs much better than constrained optimization and some existing algorithms. Simulation results demonstrate the effectiveness of CNSGA combined with topological sorting for solving constrained TTSP with multiobjectives.

作者： Zhou Li Ying ruiyao College of Economics and Management Nanjing Agricultural University Nanjing Jiangsu 210095 China

In order to study the relationship between economic globalization and industrial pollution, this paper developed the theoretical framework and used simultaneous equations. The result shows that economic globalization has influences on the industrial pollution mainly by the direct effect of scale, structure and technology as well as the indirect effect of income and policy. Considering all the factors, economic globalization, especially foreign direct investment (FDI), will reduce industrial pollution, in which technology spillover effect plays an important role.

Development of Calculation Software for Automotive Side Swing Door Closing Energy

引用

Chinese Journal of Mechanical Engineering 2010年第6期23卷 690-698页

作者： GAO Yunkai XU ruiyao YANG Lei MA Jtmjie College of Automotive Engineering Tongji University Shanghai 201804 China Pan Asia Technical Automotive Center Co. Ltd. Shanghai 201201 China

The existing research of the automotive side swing door and the closing angle via tests and simulations. In these tests, the closing energy is mainly conducted by measuring the closing energy door closing velocity and initial door closing angle are usually not taken into consideration, so the accuracy of the test data cannot be ensured, and, meanwhile, simulations require a great deal of manpower and time. Moreover, frequent tests would give rise to the increasing research and development costs. In this paper, in response to the deficiencies of these current methods, the complicated door closing process is decomposed into the closing processes of different subsystems of door, which includes weather strip seal＇, air-binding effect, door weight, hinge, check-link and latch. Mathematical models of those subsystems are established according to their working principles during the door closing process. In addition to the theoretical research, an Excel-based software using Visual Basic Application programming language is developed to realize the mathematical models, which aims to calculate the energy consumption of the subsystems. The energy consumption of different subsystems of a production vehicle door is measured to verify the accuracy of the calculation sottware developed. The proposed research provides not only the theoretical basis for the future door closing energy research, but also an interactive method and system, effectively improving the quality and efficiency of vehicle door design.
