Model-Driven Development (MDD) uses models to guide the development of software systems. However, models are usually conceived to be used by software professionals, so it is quite difficult for end-users to understand them because they are not familiar with domain-specific languages or modeling tools as software professionals are. This makes the end-users' involvement within MDD approaches a difficult...
Now, Beijing Radio and Television University (abbreviated as BRTVU) undertakes the task of building and running Beijing Open University. To achieve the goals well, BRTVU has design and developed Beijing Open Learning System. The system provides one-stop services around students and their leaning process. The system pays attention to learning activities, and assures educational quality through the...
Digital forensic analysis techniques have been significantly improved and evolved in past decade but we still face a lack of effective forensic analysis tools to tackle diverse incidents caused by emerging technologies and the advances in cyber crime. In this paper, we propose a comprehensive framework to address the efficacious deficiencies of current practices in digital forensics. Our framework,...
Agile processes emphasize collaboration. We were interested in studying collaboration in agile teams including interaction designers, since the integration of user interaction design processes and software development processes is still an open issue. This study focused on designer and developer collaborations in the early stages of project work at four workplaces. We found designer-developer collaborations...
With the continuous development of information technology, warehouse management information system is advancing more and more professionally when an increasing number of enterprises increase their investments on the construction of warehouse management information system. In this background, this paper proposes overall design ideas about the system architecture and function frameworks of warehouse...
A home is smart when, being aware of its own state and that of its users, is capable of controlling itself in order to support the user wishes and thus improving their quality of life. This holds both for users with special needs and for those with ordinary domestic needs. In this paper, we overview the Smart Homes for All project which represents the current state of the art with respect to software...
It has been long recognized that software development in industry is often iterative while new requirements and challenges arise along with software evolution. One of general rules for software design is to degrade coupling between modules so that software architecture is flexible and scalable. Along with software evolution it is better to keep user interface stay similar which helps users to upgrade,...
Automated tracing tools employ information retrieval (IR) methods to recover traceability links between software artifacts. A large body of research is available on the back-end design of such tools, including artifacts indexing and the underlying IR mechanism. In contrast, less attention has been paid to the front-end presentation of the retrieved results. This paper describes TraCter, a result categorization...
The ever-growing market pressure and complex products demand high quality work and effectiveness from software practitioners. This relates also for the methods and tools they use for the development of software-intensive systems. Validation and verification (V&V) are the cornerstones of the overall quality of a system. By performing efficient V&V activities to detect defects during the early...
End-user programming is a term that refers to computer programming carried out by end users who do not necessarily have a background in writing programs in conventional programming languages. There is much interest amongst end-users to be able to write their own programs. In order to support end-user programming, the concept of Block Based Software Development has been introduced. In this environment,...
The main objective of this study is to explore how to design the user interfaces of handheld device based on Android. The methodology of UI design based on Android is summarized through discussing the different tasks of three representative roles --requirements analyst; UI designer; software engineer in the life cycle of software development. Most of the current research is to discuss the realization...
A multi-tenant software application is a special type of highly scalable, hosted software, in which the application and its infrastructure are shared among multiple tenants to save development and maintenance costs. The limited understanding of the underlying architectural concepts still prevents many software architects from designing such a system. Existing documentation on multi-tenant software...
Nowadays people pay attention to automated test as well as to test system. It has become the important question that how to use the test system convenient. Therefore, the software automated testing system based on step is proposed, which include test case, test execution, log analyzer. It is capable of producing the useful "step" abstracted in the test requirement and enhancing testing efficiency...
Applications based on SaaS platform have been appeared as services for common users and enterprise users and an integration management of literature contents of libraries in the country is needed in the future. SaaS based literature contents integration has not been done here yet. Therefore, this paper presents SaaS based technology which integrates literature contents of public organizations or libraries...
Modern power-electronic systems need real-time simulations with short frame times to minimize switch-timing errors. At ESTS'09 we reported using FPGAs to achieve frame times as low as 400nS. We also described a non-real-time implementation of a multi-rate benchmark of an unmanned underwater vehicle. Recent research has resulted in a real-time implementation of the UUV benchmark with hardware in the...
This paper describes the architecture of the functional electrical stimulation systems developed in the context of the TIME European project. Contributions are the definition of a generic FES architecture and the specialization of this architecture, depending on the applicative context, by the deployment, the programming and the control of hardware units, notably stimulation ones. This specialization...
The RST multi-touch technique allows one to simultaneously control Rotations, Scaling, and Translations from multi-touch gestures. We conducted a user study to better understand the impact of directness on user performance for a RST docking task, for both 2D and 3D visualization conditions. This study showed that direct-touch shortens completion times, but indirect interaction improves efficiency...
At the International Space Station (ISS) Mission Control Center, flight controllers and mission support staff utilize a large number of web-based applications to perform mission operations and crew support tasks. Although access to these applications is through a common web portal, they are separate systems, developed independently and in isolation from one another. To integrate information across...
Call Center System is a system of realizing communication, services and production control, which reasonably deals with information and material process and manages them by advanced communication and computer technology. The paper introduces the mainly implementation of mini call center system and the application in Anti-counterfeit Identification System in detail. The system is designed in term of...
Smart Grid is gradually prevalent to human's daily life. More customers hope their home grids smarter to realize energy saving, intelligent controlling and real-time monitoring. The advent of Home Area Network (HAN) supported by multiple IEEE network technologies makes the thinking true together with difficulties and challenges on the field designs and assignments. Simulation is important for analysis...
