Because of indeterminateness of the environment and delay of the communication, deep space spacecraft is required to be autonomous. Planning technology is studied in order to realize the spacecraft autonomy. First, a multi‐agent planning system (MAPS) based on temporal constraint satisfaction is proposed for concurrency and distribution of spacecraft system. Second, timeline concept is used to describe simultaneous activity, continue time, resource and temporal constraints. Third, for every planning agent in the MAPS, its layered architecture is designed and planning algorithm based on the temporal constraint satisfaction is given in detail. Finally, taking some key subsystems of deep space explorer as an example, the prototype system of MAPS is implemented. The results show that with the communication and cooperation of the planning agents, the MAPS is able to produce complete plan for explorer mission quickly under the complex constraints of time and resource.

The purpose of this study is to explore possible factors leading to a successful mediation in Chinese mediation shows. In China, media always play an indispensable role in information dissemination, morality advocacy and policy explanation.

This paper employed content analysis of 166 episodes of one representative mediation show, Gold Medal Mediation, and regression technique in data analysis.

Results of ordinal regression suggested that “secret talking”, rather than transparency, between disputants had significant influence on successful mediation. Function of mediators is limited in reaching full mediation. The effective factors leading to full mediation include compromise of rights, secret talking, attitude of the observer cohort. It suggests that the role of mediator is limited, rather than being over-exaggerated, in successful mediation. The successful mediation is largely dependent on disputants’ motivations. Additionally, “compromise of rights” by disputants is a key factor in solving disputes.

Findings of this study revealed the role of Chinese mediation shows in propagating mediation in contemporary Chinese society and supporting upheld morality values. Due to the nature of the chosen mediation show, some disputes take more than one episode to solve. However, this study looks at each episode without considering the integrity of the dispute. That is, if the disputes take two episodes, the coder codes the two episodes as two separate disputes instead of looking at it as one dispute.

By exploring various aspects of mediations shows, including the role of mediators, disputants and a cohort of observers, this study can both explicitly show predicted factors to successful mediations on the shows, and can implicitly examine the power and perceived justification of mediation in contemporary China via media.

The purpose of this investigation is to identify, evaluate, integrate and summarize relevant and qualified papers through conducting a systematic literature review (SLR) on the application of recommender systems (RSs) to suggest a scholarly publication venue for researcher's paper.

To identify the relevant papers published up to August 11, 2018, an SLR study on four databases (Scopus, Web of Science, IEEE Xplore and ScienceDirect) was conducted. We pursued the guidelines presented by Kitchenham and Charters (2007) for performing SLRs in software engineering. The papers were analyzed based on data sources, RSs classes, techniques/methods/algorithms, datasets, evaluation methodologies and metrics, as well as future directions.

A total of 32 papers were identified. The most data sources exploited in these papers were textual (title/abstract/keywords) and co-authorship data. The RS classes in the selected papers were almost equally used. DBLP was the main dataset utilized. Cosine similarity, social network analysis (SNA) and term frequency–inverse document frequency (TF–IDF) algorithm were frequently used. In terms of evaluation methodologies, 24 papers applied only offline evaluations. Furthermore, precision, accuracy and recall metrics were the popular performance metrics. In the reviewed papers, “use more datasets” and “new algorithms” were frequently mentioned in the future work part as well as conclusions.

Given that a review study has not been conducted in this area, this paper can provide an insight into the current status in this area and may also contribute to future research in this field.

This paper aims to explore the effective ways to utilize current awareness services (CAS) for library and information science (LIS) professionals. It seeks to identify core journals for systems librarianship based on Bradford analysis.

The study explored the methods for CAS based on literature review, followed by Bradford analysis of systems librarianship literature, which was conducted by the quantitative analysis approach.

A core journal list for systems librarianship was built based on Bradford analysis. Three effective ways to utilize CAS by table of contents (TOCs) alerts were identified.

To keep up to date with the latest literature in the field of interest, LIS professionals should take advantage of CAS. The study found three effective ways to utilize CAS by TOCs alerts and identified core journals for systems librarianship. The research can help LIS professionals efficiently navigate the information tsunami to obtain the reliable and relevant information that deserves their time and attention, and stay aware of new developments in their area of interest.

The purpose of this paper is to develop a standard procedure for Bradford analysis: export citations from research databases to a bibliographic management tool, separate the desired citation fields with bibliographic output styles, and then manipulate the empirical data, formulate graph and analyze linearity with Microsoft Excel.

The methodology mainly employed by the paper is to test the theory of Bradford's law of scattering. Based on research work and experiments, a standard procedure for Bradford analysis is to be developed.

A standard procedure for Bradford analysis is developed. The study also shows that the literature in systems librarianship follows Bradford distribution.

Many fields or disciplines of literature have been found to follow Bradford's law, which seems to offer a great potential promise for solving library problems. However, empirical Bradford analysis demands tedious computation, and sophisticated graphical formulation. This paper develops an easy operational procedure for Bradford analysis, which will shed light on problem solving in a similar bibliometric analysis.

The purpose of this paper is to implement and enhance the citation linker that enables users to search articles, journals, and books with minimal but sufficient citation metadata.

The research work was mainly based on experimental results with a large amount of specific articles, journals, books, and eBooks. Further Ex Libris was consulted during the implementation process.

The paper found ways to implement and enhance the citation linker that facilitates citation search with minimal but sufficient citation metadata. Different methods to search papers and books were identified and possible future endeavors to enhance the citation linker by Ex Libris were also suggested.

The paper elaborates how to implement and enhance the citation linker that facilitates citation search with minimal but sufficient citation metadata. The author did not find any research work specifically focused on configurations of the citation linker and their effects on search results for users, so the implementation experience presented in this paper should be singularly instructive for libraries implementing their citation linkers.

The purpose of this paper is to recount the implementation process of the special effects (SFX) linking to Journal Citation Reports (JCR) at the Briggs Library, South Dakota State University.

Following the standard procedure developed by this paper, the research work consulted Ex Libris Customer Center, Listservs and library science literature for existing solutions to implement the SFX linking to JCR. The integration of JCR with SFX at University of Iowa Libraries was identified. Based on their implementation experience, the Briggs Library developed a more efficient method, which followed SFX standards.

A standard procedure has been developed that should be adopted for implementing new SFX services. A new target parser for JCR was created, which can become a global SFX target parser once its responsibility for updates is transferred to Ex Libris. The new method for implementing the SFX linking to JCR was invented.

The paper provides a standard procedure for implementing new SFX services. The method for implementing the SFX linking to JCR should be instructive when implementing similar projects.

The purpose of this study is to improve the position and posture accuracy of posture alignment mechanism. The automatic drilling and riveting machine is an important equipment for aircraft assembly. The alignment accuracy of position and posture of the bracket type posture alignment mechanism has a great influence on the operation effect of the machine. Therefore, it is necessary to carry out the kinematic calibration.

Based on analysis of elastic deformation of the bracket and geometric errors of the posture alignment mechanism, an improved method of kinematic calibration was proposed. The position and posture errors of bracket caused by geometric errors were separated from those caused by gravity. The method of reduction of dimensions was applied to deal with the error coefficient matrix in error identification, and it did not change the coefficient of the error terms. The target position and its posture were corrected to improve the error compensation accuracy. Furthermore, numerical simulation and experimental verification were carried out.

The simulation and experimental results show that considering the influence of the elastic deformation of the bracket on the calibration effect, the error identification accuracy and compensation accuracy can be improved. The maximum value of position error is reduced from 5.33 mm to 1.60 × 10⁻¹ mm and the maximum value of posture error is reduced from 1.07 × 10⁻³ rad to 6.02 × 10⁻⁴ rad, which is superior to the accuracy without considering the gravity factor.

This paper presents a calibration method considering the effects of geometric errors and gravity. By separating position and posture errors caused by different factors and correcting the target position and its posture, the results of the calibration method are greatly improved. The proposed method might be applied to any parallel mechanism based on the positioner.
