Detecting Design Patterns in Object-Oriented Program Source Code by Using Metrics and Machine Learning

Detecting well-known design patterns in object-oriented program source code can help maintainers understand the design of a program. Through the detection, the understandability, maintainability, and reusability of object-oriented programs can be improved. There are automated detection techniques;however, many existing techniques are based on static analysis and use strict conditions composed on class structure data. Hence, it is difficult for them to detect and distinguish design patterns in which the class structures are similar. Moreover, it is difficult for them to deal with diversity in design pattern applications. To solve these problems in existing techniques, we propose a design pattern detection technique using source code metrics and machine learning. Our technique judges candidates for the roles that compose design patterns by using machine learning and measurements of several metrics, and it detects design patterns by analyzing the relations between candidates. It suppresses false negatives and distinguishes patterns in which the class structures are similar. As a result of experimental evaluations with a set of programs, we confirmed that our technique is more accurate than two conventional techniques.

THE DESIGN AND IMPLEMENTATION OF THE IEEE 802.11 MAC BASED ON SOFT-CORE PROCESSOR AND RTOS

Evidence-based optimization of integrated traditional Chinese and Western medicine therapies for prevention and treatment of coronary heart disease： design and implementation

As a chronic disease that seriously endangers public health, the number of coronary heart disease （CHD） patients in China has increased in recent years. There is great potentiality to integrate traditional Chinese and Western medicine therapies to prevent and treat CHD in clinical practice. However, most of the current integrated therapies still lack sufficient high-quality evidence, and the key links in how to apply are unclear. It is urgent to optimize them through evidence-based research to further improve the effectiveness. Therefore, we propose strategies to conduct evidence-based optimization of integrated traditional Chinese and Western medicine therapies in prevention and treatment of progressive cardiovascular diseases. These are integrated clinical trial design, attention to the key links of taking effect, combination of clinical and basic research. Based on the strategies, we started the national key research and development project ＂Evidence-based optimization research of TCM therapies in prevention and treatment of CHD （angina pectoris - myocardial infarction - heart failure）＂, which is expected to be a new paradigm in the field.

Research on object-oriented SOC design methodology

The growing complexity of System on Chip （SOC） requres a system level specicanon and design approach. High-level languages such as C＋＋/SystemC can play multiple roles in system design as target languages. There are many practical problems in the application of object-oriented methods for this goal. Based on the analysis of traditional and system-level design methodology, a new object-oriented SOC design methodology with object-oriented design patterns is proposed, which emphasizes high-level design and verification. Aiming at the final goal of developing design patterns specific to SOC design, the reuse of design patterns in SOC systems and the capability of new SOC design patterns are discussed. With the illustration of some concrete examples of SOC design patterns, the application of object-oriented design methodology in the SOC design process is presented.

LOW-ENERGY DESIGN METHODS AND ITS IMPLEMENTATION IN ARCHITECTURAL PRACTICE: STRATEGIES FOR ENERGY-EFFICIENT HOUSING OF VARIOUS DENSITIES IN TEMPERATE CLIMATES

With mounting concerns over climate change and urban population growth,the demand for sustainable housing based on low-energy designs is steadily increasing.A variety of low-energy design methods have been developed to reduce energy and resource consumption;however,research shows that the implementation of such methods has been surprisingly limited.In addition,while the degree of housing density is understood to have an impact on low-energy designs,what that impact is and how it can be strategically applied have not been adequately researched.This research examines how low-energy designs are applied in housing types with various densities in temperate climates,identifies the issues and problems pertaining to the implementation of passive and active design strategies.This research uses a survey,which asks design practitioners to rate the merits of various low-energy design strategies and assesses how often these approaches are implemented in practice.The study uncovers discrepancies between perceived importance of low-energy design aspects and their practical implementation,finding that certain low-energy strategies can be more effective when they are incorporated in an early stage of the design process.

Exploration on 5E Teaching Principle-based Education for the Object-oriented Software Construction Course

Most current object-oriented programming courses offered by domestic colleges and universities generally focus on the object-oriented programming language itself,i.e.,the programming grammar of the language,but ignore the design pattern.However,design patterns are essential to software engineering because they can solve common problems in software design and improve code reuse,readability,extensibility,and reliability.Our Object-oriented Software Construction Course is creative since it aims at cultivating students’object-oriented thinking as well as basic abilities required to construct high-quality,object-oriented software.Specifically,we exploit the 5E teaching principle during the education of this course,and present the whole pipeline in the paper.We also provide one case of the factory pattern to further demonstrate the implementation of the 5E teaching principle in the course.The effect of the 5E teaching principle has also been demonstrated.
