As the core information system, the Unified Process Management (UPM) system covers the critical business processes in large enterprises. To achieve stable operation of the system and high quality of the processes is the key requirements from these enterprises. The original UPM system has ambiguous IT roles and responsibilities and lacks of important management schemes in the course of software development,...
Signal-oriented software architecture is a trend for universal automatic test system development, and the establishment of a platform providing unifying external signal interface and testing services function is a key techniques for signal-oriented programming. Automatic-test universal supported platform isolates the use of resources and control details, hides the concrete realization of the relevant...
In this paper, we present a tool supported approach to perform efficient regression testing of web services. Functional and non-functional web service testing is done with the help of WSDL parsing and regression testing is performed by identifying the changes made thereafter. We identify, categorize, and capture the web service regression testing needs into three different categories, namely, changes...
Web applications evolve at a very fast rate, to accommodate new functionalities, presentation styles and interaction modes. The test artefacts developed during web testing must be evolved accordingly. Among the other causes, one critical reason why test cases need maintenance during web evolution is that the locators used to uniquely identify the page elements under test may fail or may behave incorrectly...
Large legacy applications are rapidly becoming less practical for both the organizations they service, and for the organizations responsible for servicing them. This paper establishes a process model for refining the initial concept associated with overhauling legacy enterprise software applications, and examines a case study of that process as applied to a real-world legacy software system to demonstrate...
When properly employed, oil mist lubrication offers many benefits to the operation of electric motors with rolling element bearings. Cooler operating temperatures, increased reliability, and decreased maintenance issues are some of the achievable advantages associated with this system. However, there are also a host of concerns associated with its use. The costs of installing and operating a mist...
Legacy to Service-Oriented Architecture migration approaches have been extensively researched over the last decade, primarily to reuse the valuable business logic that resides within legacy applications. Interestingly, most of the proposed approaches fail to cover the complete process from the technological, organizational and business perspectives. This paper presents a structured six-phase process...
As systems/circuits degrade or high failure performance trends occur over time, there is an increased probability of predicting with reasonable confidence, when a given assembly or component is likely to experience an insipient fault or a cause a mission failure. Also, performance trends can be applied to algorithms to enhance the testing process. However, profound predictions can be made accurately...
Heating Ventilation and Air Conditioning (HVAC) system energy consumption, on average, accounts for 40% of an industrial site's total energy consumption. Studies have demonstrated that continuous commissioning of building systems for optimum efficiency can yield savings of an average of over 20% of total energy cost. Automated Fault Detection and Diagnosis (AFDD) can be used to assist the commissioning...
With technologies shrinking and design complexity increasing, it becomes crucial that embedded in chip test and repair solutions keep up with the advances in order to consistently provide superior chip quality and yield optimization. The embedded test approaches developed for designs done a few years ago are not sufficient for today's designs, which are bigger, faster, hierarchical and much more sensitive...
Refactoring legacy code can be a major impediment for teams transforming to agile due to the high cost of manual regression testing of frequent (typically 2-week) releases. Also, attempts to implement automated tests may involve technical and cost issues. In this report we present a new and more systematic approach to refactoring we have found to be successful for refactoring legacy code that has...
A virtual-metrology-based (VM-based) baseline-predictive-maintenance (BPM) scheme was proposed by the authors recently. By applying the BPM scheme, fault diagnosis and prognosis can be accomplished and the requirement of massive historical failure data can also be released. The accuracy of the BPM scheme highly depends on the correctness of the baseline models in the BPM scheme. The samples of creating...
This paper presents the future reasonable and feasible technology of prognostics and health management (PHM) for the Unmanned Aerial Vehicle (UAV). Based on the introduction of the System Health Management (SHM) for complex systems, we propose an SHM system framework and architecture for UAV to improve the reliability and maintenance for the complex UAV systems. In this framework, the related state-of-arts,...
The quality of battle damage location process (BDLP) is very important for the efficiency of damage location. The person's location ability can also be reacted by it. However, measuring complexity of BDLP is a rather new area of research with only a small number of contributions. So the complexity of BDLP is put forward to assess the BDLP's quality. The diagram entropy model which applied on the program...
Along with the development of tracing technique, the acquired data turns to be increasingly three-dimensional and complicated in quality traceability of transmission assembling, which requests of offering more scientific tracing statistical method of conversion from date information to decision information. In the paper, a statistical method is put forward based on Kruskal-Wallis test in light of...
In recent years, the newly-developed army products have set forth design requirements on quality characteristics such as reliability, maintainability, indemnificatory, testability and security in the proposal stage, which becomes an assessment index for the common shooting range appraisal and type test. However, the test and assessment of indexes including indemnificatory, testability and security...
Multiple medium voltage 3MW self-excited generators failed at startup following field testing. Initially it was reported that only insulation resistance and polarization index testing was performed. However, forensic evidence showed tunneling in the insulation system that could only come from high energy testing. In this paper we will discuss the steps in performing forensic investigations of electric...
It is good engineering practice to routinely test the electrical components and critical cables located within your system. Once testing is complete, it is prudent to develop a plan to address concerns identified from the electrical assessment. This presentation will briefly address electrical system testing followed by options available to the cable reliability engineer for correcting issues identified...
Test automation, which involves the conversion of manual test cases to executable test scripts, is necessary to carry out efficient regression testing of GUI-based applications. However, test automation takes significant investment of time and skilled effort. Moreover, it is not a one-time investment: as the application or its environment evolves, test scripts demand continuous patching. Thus, it...
Release engineering deals with all activities in between regular development and actual usage of a software product by the end user, i.e., integration, build, test execution, packaging and delivery of software. Although research on this topic goes back for decades, the increasing heterogeneity and variability of software products along with the recent trend to reduce the release cycle to days or even...
