With the development of science and technology, the systems become more and more complex, and the difficulty of system development and maintenance also increases. To solve this problem, researchers propose MBSE(Model-Based Systems Engineering) and its standard system language SysML. At present, there are not many system modeling tools, and their scalability and quality need to be improved. This paper explores the design and testing of MOF(Meta Object Facility) based on the command pattern, trying to improve the expansibility and software quality of SysML modeling tools. Firstly, the MOF layer based on the command pattern is implemented to maintain the model data, then an existing modeling platform is refactored based on this base layer, and a large number of test codes are generated to ensure the reliability of the system. The experimental results show that the scalability and reliability of the system have been effectively improved.

As software design pattern, connnand pattern encapsulates operation requests as command objects, which is benefit for the realization of queuing requests, recording logs and undo operations. Aiming at the poor universality of classical command pattern and combining with the new characteristic of variadic template in C++ 11, the variadic parameter command pattern that is of great unfversallty is proposed MVC architecture separates the GUI and model logic of application, which can facilitate the development and maintenance. The design that inserting command layer into MVC is introduced and the MCVC architecture is proposed

Proposed a extend design pattern, which oriented distributed environment. Design framework in which import some components, such as command bus, command executor. Design the structure class diagram of the pattern. Expatiated components' specific function, and analyses the command execution process in the pattern. Based on the pattern, when developers design command classes, there is no need to consider how to sequence the command object and send it to server, and they don't worry about receiving data from server and anti-serialize from the received data. Conclude that developers can use command pattern in a network transparent manner in accordance with the original way.

The implementation of an extensible system for comparison and visualization of class ordering methodologies

In this paper we present the design and implementation of a system that exploits well-known design patterns to facilitate construction of an extensible system for comparison and visualization of ordering methodologies for class-based testing of C++ applications. Using our implementation, we present a comparative study and evaluation of two advanced ordering methodologies: the edge based approach by Briand et al., and the Class Ordering System (COS) introduced in this paper. We compare two variations of the approach by Briand and three variations of the COS system and draw conclusions about the number of edges removed, and therefore the number of stubs that must be constructed, using each approach. We also compare the run-time efficiency of each approach and raise some interesting questions about edge type considerations for removal in the presence of cycles in the ORD. Using the design patterns together with the dot tool from the Graphviz package, we incorporate visualization of the ORD and the edge removals into our system. We present details and graphical visualization of the edge removal process. (C) 2005 Elsevier Inc. All rights reserved.

The Discovery Channel Telescope (DCT) is a 4.3-meter astronomical research telescope being built in northern Arizona as a partnership between Discovery Communications and Lowell Observatory. The project software team has designed and partially implemented a component-based system. We describe here the key features of that design (state-based components that respond to signals) and detail specific implementation technologies we expect to be of most interest: examples of the command pattern, State pattern, and XML-based configuration file handling using LabVIEW classes and shared variables with logging and alarming features.

As one of the major Chinese dialects, Hakka typically has a tone system with six lexical tones. The traditional 5-level notation of tones in Hakka varies in previous references due to its subjective and relative nature. In order to overcome the limitations of the traditional approach, the command-response model for the process of F-0 contour generation is employed to analyze quantitatively the tones in continuous speech of two varieties of Hakka, spoken in Meixian and in Shataukok, respectively. By providing both phonological descriptions to each tone type and quantitative approximations to continuous F-0 contours, the model-based approach provides an efficient connection between phonetics and phonology of Hakka tones.

Thai speech synthesis by rule is developed using cepstral parameters. To synthesize the pitch contour of Thai tone, we applied an extension of Fujisaki's model for tonal languages. According to our study on pitch contour of five Thai tones using this model, the result shows that to synthesize the pitch contour of these five Thai tones, the command pattern for the local F-0 components needs both positive and negative commands.

Cílem této práce je vytvoření herního dema v herním enginu Unity. Demo se skládá ze dvou částí. První částí je hra samotná, kde hráč ovládá kuličku, se kterou překonává překážky. Druhou částí je editor, který umožňuje vytváření dalších úrovní hry. V práci lze najít stručné rozebrání existujících her s podobnou tématikou a porovnání herních enginů. Rovněž se zde nachází popis návrhu a implementace obou částí dema.
