| 1 | WFRFT modulation recognition based on HOC and optimal order searching algorithm显示文摘A hybrid carrier(HC) scheme based on weighted-type fractional Fourier transform(WFRFT) has been proposed recently.While most of the works focus on HC scheme's inherent characteristics, little attention is paid to the WFRFT modulation recognition.In this paper, a new theory is provided to recognize the WFRFT modulation based on higher order cumulants(HOC). First, it is deduced that the optimal WFRFT received order can be obtained through the minimization of 4 th-order cumulants, C_(42). Then, a combinatorial searching algorithm is designed to minimize C_(42).Finally, simulation results show that the designed scheme has a high recognition rate and the combinatorial searching algorithm is effective and reliable. | LIANG Yuan DA Xinyu WU Jialiang XU Ruiyang ZHANG Zhe LIU Hujun | 2018 | Journal of Systems Engineering and Electronics2018，29，3： | 6 |
| 2 | Adaptive backtracking search optimization algorithm with pattern search for numerical optimization显示文摘The backtracking search optimization algorithm(BSA) is one of the most recently proposed population-based evolutionary algorithms for global optimization. Due to its memory ability and simple structure, BSA has powerful capability to find global optimal solutions. However, the algorithm is still insufficient in balancing the exploration and the exploitation. Therefore, an improved adaptive backtracking search optimization algorithm combined with modified Hooke-Jeeves pattern search is proposed for numerical global optimization. It has two main parts: the BSA is used for the exploration phase and the modified pattern search method completes the exploitation phase. In particular, a simple but effective strategy of adapting one of BSA's important control parameters is introduced. The proposed algorithm is compared with standard BSA, three state-of-the-art evolutionary algorithms and three superior algorithms in IEEE Congress on Evolutionary Computation 2014(IEEE CEC2014) over six widely-used benchmarks and 22 real-parameter single objective numerical optimization benchmarks in IEEE CEC2014. The results of experiment and statistical analysis demonstrate the effectiveness and efficiency of the proposed algorithm. | Shu Wang Xinyu Da Mudong Li Tong Han | 2016 | Journal of Systems Engineering and Electronics2016，27，2： | 5 |

| 6 | A review of validation methods for building energy modeling programs显示文摘Building energy simulation analysis plays an important supporting role in the conservation of building energy.Since the early 1980s,researchers have focused on the development and validation of building energy modeling programs(BEMPs)and have basically formed a set of systematic validation methods for BEMPs,mainly including analytical,comparative,and empirical methods.Based on related papers in this field,this study systematically analyzed the application status of validation methods for BEMPs from three aspects,namely,sources of validation cases,comparison parameters,and evaluation indicators.The applicability and characteristics of the three methods in different validation fields and different development stages of BEMPs were summarized.Guidance were proposed for researchers to choose more suitable validation methods and evaluation indicators.In addition,the current development trend of BEMPs and the challenges faced by validation methods were investigated,as well as the existing progress of current validation methods under this trend was analyzed.Subsequently,the development direction of the validation method was clarified. | Xin Zhou Ruoxi Liu Shuai Tian Xiaohan Shen Xinyu Yang Jingjing An Da Yan | 2023 | Building Simulation2023，16，11： | 0 |
| 7 | Near-real-time global gridded daily CO_(2) emissions显示文摘Precise and high-resolution carbon dioxide(CO_(2))emission data is of great importance in achieving carbon neutrality around the world.Here we present for the first time the near-real-time Global Gridded Daily CO_(2)Emissions Dataset(GRACED)from fossil fuel and cement production with a global spatial resolution of 0.1°by 0.1°and a temporal resolution of 1 day.Gridded fossil emissions are computed for different sectors based on the daily national CO_(2)emissions from near-real-time dataset(Carbon Monitor),the spatial patterns of point source emission dataset Global Energy Infrastructure Emissions Database(GID),Emission Database for Global Atmospheric Research(EDGAR),and spatiotemporal patters of satellite nitrogen dioxide(NO2)retrievals.Our study on the global CO_(2)emissions responds to the growing and urgent need for high-quality,fine-grained,near-real-time CO_(2)emissions estimates to support global emissions monitoring across various spatial scales.Weshow the spatial patterns of emission changes for power,industry,residential consumption,ground transportation,domestic and international aviation,and international shipping sectors from January 1,2019,to December 31,2020.This gives thorough insights into the relative contributions from each sector.Furthermore,it provides the most up-to-date and fine-grained overview of where and when fossil CO_(2)emissions have decreased and rebounded in response to emergencies(e.g.,coronavirus disease 2019[COVID-19])and other disturbances of human activities of any previously published dataset.As the world recovers from the pandemic and decarbonizes its energy systems,regular updates of this dataset will enable policymakers to more closely monitor the effectiveness of climate and energy policies and quickly adapt. | Xinyu Dou Yilong Wang Philippe Ciais Frédéric Chevallier Steven J.Davis Monica Crippa Greet Janssens-Maenhout Diego Guizzardi Efisio Solazzo Feifan Yan Da Huo Bo Zheng Biqing Zhu Duo Cui Piyu Ke Taochun Sun Hengqi Wang Qiang Zhang Pierre Gentine Zhu Deng Zhu Liu | 2022 | The Innovation2022，3，1： | 0 |
| 8 | A novel AC turning on behavior model based on survival analysis显示文摘Occupant control behavior is a key factor affecting the energy consumption of building air-conditioners(ACs).The operating behavior of ACs and their models in office buildings have been investigated extensively.However,although the thermal sensation of occupants is affected by their previous thermal experience,few researchers have attempted to incorporate this effect quantitatively in models of AC turning on behavior.Not considering the cumulative effect may result in inaccurate predictions.Therefore,in this study,a survival model is proposed to describe AC turning on behavior in office buildings under the cumulative dimension of time.Based on a dataset containing environmental parameters and occupant behavior information,as well as considering occupants entering a room as the starting event and turning on an air-conditioner as the end event,the endurance time before an AC is turned on is investigated,and a survival model is used to predict the probability of the AC turning on due to environmental factors.Based on a switch curve,confusion matrix,and tolerance–time curve,the prediction results of the survival model are analyzed and validated.The results show that a tolerance temperature of 29℃and a tolerance duration setting of 1 h can effectively model the turning on behavior of the AC.In addition,based on comparison results of different models,the survival model presents a more stable switching curve,a higher F1 score,and a tolerance curve that is more similar to reality.Different tolerance durations,as well as static and dynamic tolerance temperature settings,are considered to optimize the model.Furthermore,the AC energy consumption is calculated under the survival model and the traditional Weibull model.Simulation results were compared with measurement,and the survival model verified the improvement effect of prediction accuracy by 8%than the Weibull model.By considering the time-transformed accumulation of physical environmental factors,the accuracy of AC turning on models can be improved,thus providing an effective reference for future building energy consumption simulations. | Yuxin Lu Xinyu Yang Xin Zhou Jingjing An Xiaomin Wang Kun Zhang Da Yan | 2023 | Building Simulation2023，16，7： | 0 |
