Writing Acceptable Patches: An Empirical Study of Open Source Project Patches
No full textSoftware developers submit patches to handle tens or even hundreds of bugs reported daily. However, not all submitted patches can be directly integrated into the code base, since they might not pass patch review that is adopted in most software projects. As the result of patch review, incoming patches can be rejected or asked for resubmission after improvement. Both scenarios interrupt the workflow of patch writers and reviewers, increase their workload, and potentially delay the general development process. In this paper, we aim to help developers write acceptable patches to avoid patch rejection and resubmission. To this end, we derive a comprehensive list of patch rejection reasons from a manual inspection of 300 rejected Eclipse and Mozilla patches, a large-scale online survey of Eclipse and Mozilla developers, and the literature. We also investigate which patch-rejection reasons are more decisive and which are difficult to judge from the perspective of patch reviewers. Our findings include 1) suboptimal solution and incomplete fix are the most frequent patch-rejection reasons 2) whether a patch introduces new bugs is very important yet very difficult to judge 3) reviewers reject a large patch not solely because of its size, but mainly because of the underlying reasons that induce its large size, such as the involvement of unnecessary changes 4) reviewers consider certain problems to be much more destructive than patch writers expect, such as the inconsistency of documentation in a patch and 5) bad timing of patch submission and a lack of communication with team members can also result in a negative patch review.</p

A Study on the mathematics textbooks in the era of the Great Han Empire
No full text이 글은 갑오경장(1894)과 경술 국치(1910) 사이에 간행된 산학(수학) 교재류의 목록을 확인하고, 각 텍스트의 출판과 관련된 사항, 소장처, 이본 등의 서지적 정보와 함께 이 시기 산학 교재류의 국어사 자료로서의 의의를 언어 사용 상의 측면에 초점을 두어 정리하는 것을 목적으로 한다. 이는 현대 한국어 태동기의 분과 학문의 도입 양상에 대한 연구의 일환인 한편, 학술 용어의 번역과 정착을 중심으로 이 시기의 한국어의 어휘 확장 양상을 확인하는 데에 필요한 기초 자료를 정리하는 작업의 한 부분이다. 본 연구에 앞선 산학(수학) 교재류에 대한 연구로는 산학 교재류의 서지 사항에 대해 기술한 강윤호(1973:187-199), 김봉희(1992:247-253), 한길준(2009), 오채환 외(2010) 등이 있고, 한국 수학사를 기술하면서 교재류를 함께 다룬 것으로 김용운·김용국(1982)와 이상구(2013)이 있다.This paper aims to make a whole list of the mathematics textbooks in the era of the Great Han Empire and summerize bibliographical data and linguistic characteristics in view of Korean history. In chapter 1, the author reviewed former studies which deals with the mathematics textbooks in the era of the Great Han Empire. In chapter 2, the author summerized bibliographical data of 45 volumes of 32 kinds textbooks. In chapter 3, the author described linguistic characteristics of the textbooks, especially focusing on writing systems, the use of Arabic numerals, horizontal writing, and presence of index or glossary
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters

Metal–Air Batteries: From Static to Flow System
No full textAs an emerging battery technology, metal–air flow batteries inherit the advantageous features of the unique structural design of conventional redox flow batteries and the high energy density of metal–air batteries, thus showing great potential as efficient electrochemical systems for large‐scale electrical energy storage. This review summarizes the operating principles and recent progress of metal–air flow batteries from a materials and chemistry perspective, with particular emphasis on the latest advanced materials design and cell configuration engineering, which the authors divide into three categories based on the anode species: vanadium–air, zinc–air, and lithium–air flow batteries. Since some of the capabilities developed for metal–air static batteries can be leveraged for next‐generation flow systems, classical works on conventional metal–air batteries are selected and compared with the metal–air flow systems, highlighting the prominent advantages of the latter in achieving high energy capacity and long cycle performance. At the end, a general perspective on current challenges/opportunities and future research directions to promote the commercial application of the metal–air flow battery technology is provided. The aim is to provide a comprehensive overview and to set up a road map for guiding development from conventional static to advanced flow technologies of metal–air batteries.Xiaopeng Han, Xiaopeng Li, Jai White, Cheng Zhong, Yida Deng, Wenbin Hu and Tianyi M
Hopfield Neural Networks: A updated Approach for Using Associative Memory to Improve Matrices
No full textModern Hopfield Neural Networks (MHNNs) are a class of neural networks renowned for their associative memory capabilities, which have broad applications in pattern recognition, optimization, and error correction. This dissertation explores the mathematical foundations, architectural nuances, and practical applications of MHNNs, focusing on the development of a novel energy function using the Concave-Convex Procedure (CCCP). The updated energy function enhances the network's convergence properties and robustness, addressing limitations of classical models such as low storage capacity and susceptibility to local minima.We demonstrate the efficacy of the update energy function through rigorous theoretical analysis and extensive simulation studies. Synthetic datasets with various distributional properties are generated to evaluate the network's performance in classification tasks. Our results indicate that the proposed MHNN model outperforms Original Hopfield networks and competes effectively with contemporary machine learning algorithms, including Support Vector Machines, Decision Tree, Random Forests, and Convolutional Neural Networks.In classifc Hopfield nerual network practical applications, we focus on image restoration tasks, successfully reconstructing highly corrupted images, and achieving high accuracy and low restoration error. This showcases the network's potential for real-world applications in fields such as bioinformatics, natural language processing, and healthcare diagnostics.This work not only underscores the capabilities of MHNNs in associative memory and optimization tasks but also paves the way for future innovations. By integrating advanced mathematical techniques and exploring hybrid approaches, this dissertation contributes significantly to the field of neural networks and machine learning, providing a robust framework for future research and application development
Corvèe under Han
No full textThe author distinguishes between the corvee systems of Ch'in and Han. In spite of the fact that the corvee system underwent a marked change in 167 B. C. in the reign of Emperor Wen of Former Han, the fact has been hitherto almost entirely overlooked. The author tries to reconstruct the Ch'in corvee system from various sources. In the sense that these two ancient empires were despotic in their constitution there was no essential difference between their system of government, but Han succeeded in melting feudalistic residues of the Chan-kuo period into her own system, while Ch'in failed in doing so due to the short period of her rule. Moreover, Ch'in failed in taking local differences into consideration in establishing her institutions. In the author's view the reign of Emperor Wen is significant in the sense that it represents renovation of the feudalistic taxation system and of the uniform and artificial system of local administration
