It offers reusable abstract information that is helpful in solving recurring design problems. Detecting design patterns is beneficial to the comprehension and maintenance of object-oriented software systems. Several pattern detection techniques based on static analysis often encounter problems when detecting design patterns for identical structures of patterns. In this study, we attempt to detect software design patterns by using software metrics and classification-based techniques. Our study is conducted in two phases: creation of metrics-oriented dataset and detection of software design patterns. The datasets are prepared by using software metrics for the learning of classifiers. Then, pattern detection is performed by using classification-based techniques. To evaluate the proposed method, experiments are conducted using three open source software programs, JHotDraw, QuickUML, and JUnit, and the results are analyzed.展开更多

By considering how malware behaves, we can tackle the malware obfuscation problem, which cannot be processed by traditional static analysis approaches, and we can also derive the as-built behavior specifications and cover the entire behavior space of the malware samples. Although there have been several works focusing on malware behavior analysis, such research is far from mature, and no overviews have been put forward to date to investigate current developments and challenges. In this paper, we conduct a survey on malware behavior description and analysis considering three aspects: malware behavior description, behavior analysis methods, and visualization techniques. First, existing behavior data types and emerging techniques for malware behavior description are explored, especially the goals, prin- ciples, characteristics, and classifications of behavior analysis techniques proposed in the existing approaches. Second, the in- adequacies and challenges in malware behavior analysis are summarized from different perspectives. Finally, several possible directions are discussed for future research.展开更多

文摘Convective cooling by wind is crucial for large-scale photovoltaic(PV)systems,as power generation inversely correlates with panel temperature.Therefore,accurately determining the convective heat transfer coefficient for PV arrays with various geometric configurations is essential to optimize array design.Traditional methods to quantify the effects of configuration utilize either Computational Fluid Dynamics(CFD)simulations or empirical methods.These approaches often face challenges due to high computational demands or limited accuracy,particularly with complex array configurations.Machine learning approaches,especially hybrid learning models,have emerged as effective tools to address challenges in heat transfer design optimization.This study introduces a method that combines Physics-Informed Machine Learning with a Deep Convolutional Neural Network(PIML-DCNN)to predict convective heat transfer rates with high accuracy and computational efficiency.Additionally,an innovative loss function,termed the“Pocket Loss”,is developed to enhance the interpretability and robustness of the PIML-DCNN model.The proposed model achieves relative estimation errors of 2.5%and 2.7%on the validation and test datasets,respectively,when benchmarked against comprehensive CFD simulations.These results highlight the potential of the proposed model to efficiently guide the configuration design of PV arrays,thereby enhancing power generation in real-world operations.
文摘The integration of solar greenhouses into smart energy systems(SESs)remains largely unexplored,despite their potential to enhance energy sharing and hydrogen production.This review investigates the role of solar greenhouses as active energy contributors within SESs,emphasizing their biomass waste gasification for hydrogen production and their integration into district heating and cooling(DHC)networks.A structured classification of machine learning(ML)and deep learning(DL)techniques applied in forecasting and optimizing these processes is provided.Additionally,the evolution of DHC systems is analyzed,with a focus on fifth-generation DHC(5GDHC)networks,which facilitate bidirectional energy exchange at near-ambient temperatures.The review highlights that existing studies have predominantly addressed SES advancements and ML-driven energy management without considering the contributions of solar greenhouses.A novel framework is proposed,illustrating their role as prosumers capable of exchanging electricity,hydrogen,and thermal energy within SESs.Key findings reveal that integrating solar greenhouses with SESs can enhance energy efficiency,reduce carbon emissions,and improve system resilience.Furthermore,ML-driven predictive control strategies,particularly model predictive control(MPC),are identified as essential for optimizing real-time energy flows and biomass gasification processes.This study provides a foundation for future research on the technical,economic,and environmental feasibility of integrating greenhouses into SESs.The insights presented offer a pathway toward more sustainable,AI-driven energy-sharing networks,supporting policymakers and industry stakeholders in the transition toward low-carbon energy solutions.
文摘Design patterns are often used in the development of object-oriented software. It offers reusable abstract information that is helpful in solving recurring design problems. Detecting design patterns is beneficial to the comprehension and maintenance of object-oriented software systems. Several pattern detection techniques based on static analysis often encounter problems when detecting design patterns for identical structures of patterns. In this study, we attempt to detect software design patterns by using software metrics and classification-based techniques. Our study is conducted in two phases: creation of metrics-oriented dataset and detection of software design patterns. The datasets are prepared by using software metrics for the learning of classifiers. Then, pattern detection is performed by using classification-based techniques. To evaluate the proposed method, experiments are conducted using three open source software programs, JHotDraw, QuickUML, and JUnit, and the results are analyzed.

文摘Behavior-based malware analysis is an important technique for automatically analyzing and detecting malware, and it has received considerable attention from both academic and industrial communities. By considering how malware behaves, we can tackle the malware obfuscation problem, which cannot be processed by traditional static analysis approaches, and we can also derive the as-built behavior specifications and cover the entire behavior space of the malware samples. Although there have been several works focusing on malware behavior analysis, such research is far from mature, and no overviews have been put forward to date to investigate current developments and challenges. In this paper, we conduct a survey on malware behavior description and analysis considering three aspects: malware behavior description, behavior analysis methods, and visualization techniques. First, existing behavior data types and emerging techniques for malware behavior description are explored, especially the goals, prin- ciples, characteristics, and classifications of behavior analysis techniques proposed in the existing approaches. Second, the in- adequacies and challenges in malware behavior analysis are summarized from different perspectives. Finally, several possible directions are discussed for future research.

文摘The most widely used method of identification of microbial morphology and structure is microscopy,but it can be difficult to distinguish between pathogens with a similar appearance.Existing fluorescent staining methods require a combination of a variety of fluorescent materials to meet this demand.In this study,unique concentration-dependent fluorescent carbon dots(CDs)were synthesized for the identification and quantification of pathogens.The emission wavelength of the CDs could be tuned spanning the full visible region by virtue of aggregation-induced narrowing of bandgaps.This tunable emission wavelength of the specific concentration response to diverse microbes can be used to distinguish microorganisms with a similar appearance,even in a same genus.A hyperspectral microscopy system was demonstrated to distinguish Aspergillus flavus and A.fumigatus based on the results above.The identification accuracy of the two similar-looking pathogens can be close to 100%,and the relative proportions and spatial distributions can also be profiled from the mixture of the pathogens.This technique can provide a solution to the fast detection of microorganisms and is potentially applicable to a wide range of problems in areas such as healthcare,food preparation,biotechnology,and health emergency.
