This paper proposes a method to generate program graph and DD-paths automatically. Firstly, this method makes static analysis on the structured program to get the defining and using information of the variables and the structure of the program. Secondly, it draws the program graph. Thirdly, it generates the DD-paths set of each variable. Based on this method, software tester can generate DD-path automatically...
VLBI is a technique that synthesizes the signals of several telescopes to achieve a much higher resolution. Correlator is a key component in the whole VLBI system. This paper introduces the parallel implementation of the CVN(Chinese VLBI Network) software correlator. High performance computing algorithms are used to accelerate the correlation process.
How to accurately control the gate bias voltage of a Doherty RF power amplifier is an important problem that has to be resolved for developing high efficiency RF power amplifiers. This paper proposes a digital bias solution to obtain adjustable accurate bias voltage, and discusses the implementation procedure of high-accuracy bias voltage control software for Doherty RF power amplifiers in detail...
Based on the bias control technique for RF power amplifiers, this paper discusses the design of automatic temperature compensation software which can accurately control the gate voltage of RF power amplifiers with the variation of the temperature. At first the paper analyzes the temperature characteristics of RF power amplifiers, and then a solution to automatically implement temperature compensation...
Test case is one of the most important part of software testing. Reusing available test cases is an effective means to reduce the cost and improve the efficiency of software testing. In order to efficiently reuse test cases, a unified and standard format to describe test cases is needed. Therefore, this paper presents a reusing method based on ontology. The test case ontology is created by Protégé...
With the development of information technology, a large number of software products enter the maintenance phase. The maintainability of software products continues to attract people's attention. This paper proposes a new synthetic maintainability evaluation model basing on fuzzy entropy theory. In the model, the weight of different indexes is calculated by combining the entropy weight and expert weight...
A Petri Net is a graphical and mathematical modeling approach used to describe the transition of states for an information system. This paper presents a novel technique to generating test cases using a Colored Petri Net (CPN) model. The state space of a model based on CPN provides a solid basis for test cases generation in a form that can be easily manipulated. This technique is based on three testing...
Software testing process has being separated gradually from software development. As a relatively independent process, software testing process simulation and optimization has been also started to catch people's attention. It is particularly important to improve the reuse of software testing. This paper proposes a systematic way to model the software testing processes STP-NET based on HTCPN, in order...
How to measure reuse capability of a test case is critical in software test reuse research. A dynamic method based on Bayesian network is proposed for measure the reuse of test case. It collects the information of user's searching and reusing test cases, and then analysis the test case's reuse capability which give basis for consulting to users. The prominent characteristic of this method is that...
Test cases are one of the most important assets in the testing process. This paper presents the testing ontology based SWEBOK and software quality model. The management and retrieval of test cases will play a vital role in test cases reuse. The keyword-based, as well as facet-based retrieval cannot meet user's flexible query requirement because of lack of semantic information. SWEBOK provides a broad...
As terminal of through-the wall radar, the main function of display&control system is accomplishing information transfer between the user and the radar: Configure the radar system according to the user, and return detected result in a laconic and effective way finally. Based on all above, the article introduced a new way to construct display&control system, and then relevant software structure...
