基于ATMEGA128的汉字显示屏设计

在现代工业控制和一些智能化仪器仪表中,越来越多的场所需要用点阵图形显示器显示汉字,用以显示仪器当前的运行状况。汉字显示方式是先根据所需要的汉字提取汉字点阵（如16×16点阵）,将点阵文件存方ROM,形成新的汉字编码,而在使用时刚需要先根据新的汉字编码组成语句,再由MCU根据新编码提取相应的点阵进行汉字显示。本设计是以单片机的基本语言C语言来进行软件设计,以ICCAVR进行软件编译,硬件连接是用Atmega128单片机的I／O端口与AMPIRE128×64液晶屏相连,从而达到在液晶屏上显示汉字的目的。     

与拼音文字不同的汉字家族效应

利用快速命名实验范式,采用4类80个汉语形声字,探查了汉字形声字声旁家族大小对整字语音通达的影响。通过反应时分析发现,汉字阅读中也存在家族效应,但是与拼音文字正好相反,声旁家族越大,反应时越长,在不规则汉字阅读中表现更为明显,显示了汉字语音通达有别于拼音文字的特殊性。作者提出了一个汉字形声字阅读的模型,以期更深入地揭示汉字形声字阅读的认知机制。

Text mining and software engineering: an integrated source code and document analysis approach

Documents written in natural languages constitute a major part of the artefacts produced during the software engineering life cycle. Especially during software maintenance or reverse engineering, semantic information conveyed in these documents can provide important knowledge for the software engineer. A text mining system capable of populating a software ontology with information detected in documents is presented. A particular novelty is the integration of results from automated source code analysis into a natural language processing pipeline, allowing to crosslink software artefacts represented in code and natural language on a semantic level.

A Hardware Platform Framework for an Intelligent Vehicle Based on a Driving Brain

The type, model, quantity, and location of sensors installed on the intelligent vehicle test platform are different, resulting in different sensor information processing modules. The driving map used in intelligent vehicle test platform has no uniform standard, which leads to different granularity of driving map information. The sensor information processing module is directly associated with the driving map information and decision-making module, which leads to the interface of intelligent driving system software module has no uniform standard. Based on the software and hardware architecture of intelligent vehicle, the sensor information and driving map information are processed by using the formal language of driving cognition to form a driving situation graph cluster and output to a decision-making module, and the output result of the decision-making module is shown as a cognitive arrow cluster, so that the whole process of intelligent driving from perception to decision-making is completed. The formalization of driving cognition reduces the influence of sensor type, model, quantity, and location on the whole software architecture, which makes the software architecture portable on different intelligent driving hardware platforms.

Visual language and software development environment for image processing

The Khoros system integrates multiple user interface modes, code generators, instructional aids, data visualization, and information processing to produce a comprehensive image processing research tool. This system can easily be tailored to other application domains because the tools of the system can modify themselves as well as the system. This attribute is important in a system that is designed to be extensible and portable. The Khoros infrastructure consists of three major components: a high-level user interface specification, methods of software development embedded in a code generation tool set, and an interoperable data exchange format and algorithm library. These basic facilities have been used to build a set of applications for performing image processing research, algorithm development, and data visualization. One of the most powerful features of the system is its high-level abstract visual language. Khoros is a successful demonstration of how development programming, end-user applications programming, information processing, data display, instruction, documentation, and maintenance can be integrated to build a state-of-the-art image/data processing and visualization software environment.

Product development for Chinese calligraphy using reverse engineering and rapid prototyping

Chinese calligraphy is considered to be one of the most beautiful and meaningful patterns in the world. Calligraphy is an art dating back to the earliest day of Chinese history, and widely practised throughout ancient China even to recent days. Owing to the passage of time, many old carvings of stamp characters have gradually faded. How to preserve these old Chinese cultural artifacts will be some crucial issues for today. Reverse engineering (RE) and rapid prototyping (RP) technology are considered effective tools for product development. This research combines RE, grey prediction theory in pattern processing, geometric modeling for constructing the characters of Chinese calligraphy and RP for model making. First, the written Chinese calligraphy is scanned by a scanner. By using image processing, the contours of the Chinese characters can be detected. The contours for the characters then turn out to be point data which can be easily processed in any computer aided design (CAD) software by using B-Spline curves to fit the points. An example is demonstrated by writing a Chinese compound word 'the fortune and treasure are coming' to show the process. Finally, a RP model is fabricated to show various applications for the products in Chinese calligraphy pattern. By this research, the gap between the Chinese calligraphy in handicraft and digital virtual design can be realized. More usefully, with this research the aesthetic aspects in the characters can be preserved.
