Abstract

In software engineering (SE) tasks, the naming approach is so important that it attracts many scholars from all over the world to study how to improve the quality of method names. To accurately recommend method names, we employ a novel framework to handle this problem. In our expeirments, nearly 8 million Java methods are collected from open source organizations as our evaluation dataset. In the first-phase recommendation, we introduce a fast and simple classifier based on the fast text neural network for reccomending potential method category. In the second-phase recomendation, we employ both two Long Short Term Memory Networks to reccomend consitent method names from each classification. Evaluation results prove that the proposed approach significantly outperforms state-of-the-art approach.

Abstract

A large-scale evaluation for current naming approaches substantiates that such approaches are accurate. However, it is less known about which categories of method names work well via such naming approaches and how's the performance of naming approaches. To point out the superiority of the current naming approach, in this paper, we conduct an empirical study on such approaches in a new dataset. Moreover, we analyze the successful naming approaches above and find that: (1) around 60% of the accepted recommendation names are made on prefixes within get, set, is, and test. (2) A large portion (19.3%) of method names successfully recommended could be derived from the given method bodies. The comparisons also demonstrate the superior performance of the empirical study.

Abstract

The performance wagon is the key stage mechanical equipment to realize rich performances and diversified changes on the stage, which can carry actors or scenery. In order to solve the problem of low intelligence and poor flexibility of the traditional performance wagon, which can not walk or rotate arbitrarily according to the designated path in accordance with the program arrangement, a new type of performance omnidirectional vehicle form based on nested structure is proposed. The structure is composed of an inner and outer nested double ring frame, and the relative motion and combined motion of the nested inner and outer double rings are realized by meshing the large gear ring of the outer ring with the tension adjustment of the inner ring and driving the pinion components. The omnidirectional vehicle for the proposed structure is designed. Based on the kinematics principle, the kinematics analysis system is carried out for the omnidirectional vehicle, and the kinematics model is established. On this basis, the track estimation is carried out and the three-dimensional model is established to analyze the dynamics of the omnidirectional vehicle. An omnidirectional vehicle platform based on the nested structure is built for system experiment and tests. The results show that the omnidirectional vehicle based on the nested structure has good mechanical performance, and can realize trajectory motion with good robustness and high precision.
