Researchers have recently achieved significant advances in deep learning techniques, which in turn has substantially advanced other research disciplines, such as natural language processing, image processing, speech recognition, and software engineering. Various deep learning techniques have been successfully employed to facilitate software engineering tasks, including code generation, software refactoring, and fault localization. Many studies have also been presented in top conferences and journals, demonstrating the applications of deep learning techniques in resolving various software engineering tasks. However,although several surveys have provided overall pictures of the application of deep learning techniques in software engineering,they focus more on learning techniques, that is, what kind of deep learning techniques are employed and how deep models are trained or fine-tuned for software engineering tasks. We still lack surveys explaining the advances of subareas in software engineering driven by deep learning techniques, as well as challenges and opportunities in each subarea. To this end, in this study, we present the first task-oriented survey on deep learning-based software engineering. It covers twelve major software engineering subareas significantly impacted by deep learning techniques. Such subareas spread out through the whole lifecycle of software development and maintenance, including requirements engineering, software development, testing, maintenance, and developer collaboration. As we believe that deep learning may provide an opportunity to revolutionize the whole discipline of software engineering, providing one survey covering as many subareas as possible in software engineering can help future research push forward the frontier of deep learning-based software engineering more systematically. For each of the selected subareas,we highlight the major advances achieved by applying deep learning techniques with pointers to the available datasets i

Chinese Chemical Letters 2003年第9期14卷 907-910页

作者： Shrong shi lin College of Chemical and Molecular Engineering Peking UniversityBeijing 100871

The reactions of triphenylpyrylium salt 1 with various anuno acids were explored and compared. The reactions with most α-amino acids yielded decarboxylation products 2 via decarboxylation. The reactions with glutamic acid, lysine and ACC (1-aminocyclopropyl-carboxylic acid) gave triphenylpyndine 8, dimer 9 and acid 5a-acc, respectively. The reactions with βand γ-amino acids yielded triphenylpyridine by intramolecular elinunation.

Research methods and performance analysis for the moderately high temperature refrigerant

引用

Science China(Technological Sciences) 2008年第8期51卷 1087-1095页

作者： shi lin ZAN Cheng Key Laboratory for Thermal Science and Power Engineering of Ministry of Education Department of Thermal EngineeringTsinghua UniversityBeijing 100084China

In China, directly dropping high temperature refrigerant into conventional compressor is considered as a dominant technical route for development of moderately high temperature heat pump. Based on this route, selection criteria for high temperature refrigerant were presented with consideration of several influencing factors. Moreover, a set of research methods were built including theoretical calculations and experimental tests. Four high temperature refrigerants from HTR01 to HTR04 were compared and analyzed. In results, firstly, HTR03 and HTR04 belonging to non-ozone depleting refrigerants could bring outstanding environmental benefits; secondly, the condenser outlet water efficiently generated by heat pump using high temperature refrigerants could cover 60°C–90°C;; finally, the feasibility of the technical route and the research methods were proved.

Designing cost-effective network-on-chip by dual-channel access mechanism

引用

Journal of Systems Engineering and Electronics 2011年第4期22卷 557-564页

作者： shijun lin Jianghong shi Huihuang Chen Department of Communication Engineering Xiamen University Xiamen 361005 E R. China

A dual-channel access mechanism to overcome the drawback of traditional single-channel access mechanism for network-on-chip （NoC） is proposed. In traditional single-channel access mechanism, every Internet protocol （IP） has only one chan- nel to access the on-chip network. When the network is relatively idle, the injection rate is too small to make good use of the network resource. When the network is relatively busy, the ejection rate is so small that the packets in the network cannot leave immediately, and thus the probability of congestion is increased. In the dual-channel access mechanism, the injection rate of IP and the ejection rate of the network are increased by using two optional channels in network interface （NI） and local port of routers. Therefore, the communication performance is improved. Experimental results show that compared with traditional single-channel access mechanism, the proposed scheme greatly increases the throughput and cuts down the average latency with reasonable area increase.

关键词： network-on-chip (NoC) system-on-chip (SoC) singlechannel access dual-channel access.
