According to the gradual expansion of power grid scale and rapid development of computer technology, the dispatching automation and control system has played an increasingly prominent role in technique support and guarantee for power grid. In this paper we designed a kind of operating monitoring and evaluation software for the smart grid dispatching and control system, and described several key technologies...
Most biomaterials are undergoing a process degradation faster than other materials. The biomaterials are often combined with other materials by various methods of treatment in order to ensure certain performance and functionality. Maintenance biomaterials must take into account both their particular as well as the evolution of experience accumulated. Treatment of the biomaterial, in many cases does...
Modern integrated development environments (IDEs) support one live codebase at a given moment, which imposes limitations to software development. For example, with only one codebase, the developer must pause development while running tests, or a static analysis, as any edit could invalidate the ongoing computation. Were the IDEs supported a copy of developer's codebase, the analyses could have run...
Data maps serve the purpose of visually representing information. They are especially useful for allowing people to grasp complex data structures. An interactive data map adds the functionality of people and systems being able to interact with the data through the use of the data map. This interaction may include navigation through parts of data structures or physically manipulating the underlying...
The article focusing on the situation of transmission network operation and maintenance introduces a monitoring and controlling management system for transmission network operation and maintenance. This paper says its principle, structure, software function and application. The whole system containing circuit monitoring device, maintenance monitoring device and the background management system uses...
The maintenance teaching, training and testing of a certain type of control and command system fails to achieve satisfied results for the limitation in quantity and complexity. This paper discusses the development of a virtual maintenance training and testing system. Based on fault cases and B/S mode, the system realizes online virtual maintenance training and testing, greatly improving the training...
Often stakeholders, such as developers, managers, or buyers, want to find out what software development processes are being followed within a software project. Their reasons include: CMM and ISO 9000 compliance, process validation, management, acquisitions, and business intelligence. Recovering the software development processes from an existing project is expensive if one must rely upon manual inspection...
Increasingly powerful processors for substation automation systems make it possible to integrate and process many functions, for both protection and control, in the same computer. This article describes possibilities, experiences and challenges for a standard platform for integrated soft protection and control of AC substations. The benefits of such a solution have been described in several papers...
The development process for a given software system is a combination of an idealized, prescribed model and a messy set of ad hoc practices. To some degree, process compliance can be enforced by supporting tools that require various steps be followed in order; however, this approach is often perceived as heavyweight and inflexible by developers, who generally prefer that tools support their desired...
We examine an attempt to implement a joint IT infrastructure between a large multi-national high-technology manufacturing firm and a large mining firm. We identify several occasions where innovation failed and the manufacturing firm could not establish a new network of partnerships with their customers enabled by the introduced IT capabilities. Our study highlights a change in the forms of materiality...
The distributed control system (DCS) is the most prevalent means of implementing batch and continuous control in the process industry. The DCS platform may also be effectively used for the evaluation and demonstration of innovative algorithms developed at a university. The integrated online advanced controls, diagnostics, data analytics, and process modeling capability of a DCS facilitate university...
Through introducing the whole operation of the electric locomotives by system monitoring software, a graphical intuitive understanding developed by configuration software. Communications between software and hardware becomes the core problem of the control system. In the system, choose the configuration software to develop the monitoring software system, which has features of well graphical intuitive...
Large software systems undergo significant evolution during their lifespan, yet often individual changes are not well documented. In this work, we seek to automatically classify large changes into various categories of maintenance tasks - corrective, adaptive, perfective, feature addition, and non-functional improvement - using machine learning techniques. In a previous paper, we found that many commits...
Monitoring system always plays the great important role in many kinds of the controlling system. Communications between software and hardware becomes the core problem of the control system. In the system, choose the configuration software to develop the monitoring software system, which has features of well graphical intuitive. The entire electric locomotive monitoring system include some function...
This paper describes a facility wide distributed control system (DCS) upgrade project at a large copper and molybdenum mineral processing operation. The innovative hardware and software technologies employed in the new control system are discussed. The planning process, migration path and simulation techniques used to ensure the success of such a large and complex DCS upgrade are described. A novel...
When changing a source code entity (e.g., a function), developers must ensure that the change is propagated to related entities to avoid the introduction of bugs. Accurate change propagation is essential for the successful evolution of complex software systems. Techniques and tools are needed to support developers in propagating changes. Several heuristics have been proposed in the past for change...
An approach to recommend a ranked list of developers to assist in performing software changes to a particular file is presented. The ranking is based on change expertise, experience, and contributions of developers, as derived from the analysis of the previous commits involving the specific file in question. The commits are obtained from a software systempsilas version control repositories (e.g.,...
The source code of a software system is in constant change. The impact of these changes spreads out across the software system and may lead to the sudden manifestation of failures in unchanged parts. To help developers fix such failures, we propose a method that, in a pre-processing stage, analyzes prior code changes to determine what functions have been modified. Next, given a particular period...
Through introducing the whole operation of the electric locomotives by system monitoring software, a graphical intuitive understanding developed by configuration software. Preparation of the entire electric locomotive operating system monitoring software locomotive operations recorded by the whole locomotive of the acquisition, the top operations Video Capture, IC card information management, historical...
Multi-core SoC created great opportunities to increase overall system performance while keeping the power in check but also created many design challenges that designers must now overcome. The challenge of doubling performance every two years used to drive superscalar design with more functional units running concurrently or deeper pipeline racing for highest frequency at the cost of higher power...
