User profiling is a typical big data service created and utilized by an increasing number of Internet venders, which maintains a customized model of interests or essential attributes of their existing users by looking for insights into their behaviors. The Internet industry's best practices indicate that user profiles can help venders much more sufficiently understand their customers. As a result,...
Performance prediction is critical in embedded system design for reducing the turnaround time of software. Using simulation to measure the performance of the whole source code is often too slow, particularly after the modification of the source code due to changes in problem specification. In this paper we present a comprehensive method that combines analytical modeling and statistical approach to...
The usefulness of broadband impedance matching to increase the bandwidth of a microstrip patch antenna is illustrated using three different antenna configurations. Measured data for a patch antenna was incorporated into commercial CAD software to design a matching network. Design limitations are also discussed. Practical design examples and experimental results are given which clearly demonstrate...
Online tutorial is a major topic in the e-learning field. With the huge and increasing number of web services and web applications, tutorials are facing challenge. The e-learning field needs an open Eco-system. Students need tutorials which guide learner in real-time context. Tutorial creators want that tutorial is convenience to transport, edit, and delivery. This paper proposes an idea of open Eco-system...
Base on the Extended Object-Oriented Petri Net, and the component evolution processes that has been proposed in our previous research, this paper applies the top-down and bottom-up strategy to stratify component models. The definition of Equivalent Model of EOOPN is given, four types of subnet Equivalent Model are analyzed and the system performance analysis methodologies corresponding to the four...
This paper studies the issue of component refinement on the bases of component evolution processes that has been proposed in authors previous research work focused on Extended Object-Oriented Petri Net. Components are refined through basic elements of software system's architectural components. The detailed idea of component refinement is discussed and a set of methods and rules relating to component...
Based on the Extended Object-Oriented Petri Net, and the component evolution processes that has been proposed in our previous research, the notion of Stochastic Petri Net (SPN) is integrated into EOOPN to facilitate the time aspect of system performance analysis. To simplify the complexity of time performance analysis, the system is further divided into layer subsystems so that the issue of state...
Base on the Extended Object-Oriented Petri Net, and the component evolution processes that has been proposed in our previous research, this paper studies the issue of component refinement. Three types of component refinement under the framework of EOOPN model, namely ABP refinement, ABT refinement and Token refinement, are proposed in this paper along with their definitions and component features...
This paper presents a modular designed dynamic positioning (DP) experiment system. Three modules are designed for the DP experiment system, which are onboard computer module, position sensing module and onshore control computer module. The hardware system and software are introduced. A PC/104 computer is used as the main controller of the onboard computer system, and an ARM microcontroller is used...
In response to the challenges for application development, deployment, running and maintenance in an open, dynamic, difficult to control for Internet platform, the concept of Internetware came into being. It is a new software architecture, which is flexible to evolution, continuously reactive and adaptive to multiple targets. Software entities form a software web, which is similar to current information...
With the development of electronic and information technology, the signal generator has been widely used in various fields of electronic technology. And the requirement of its performance is increasingly more and more superior, such as adjustable frequency and range, high frequency stability, fast conversion speed, etc. Meanwhile, Some uncommonly special waveforms are needed in some special environment,...
For CPU chips' cooling task, existing mono-variable control system has the defects of delay, fluctuation and high energy consumption. With the trend of multi-core and high frequency work pulse in CPU chips, traditional system does not fit for future cooling task. Several approaches such as chips' dissipated power nonlinear feed-forward, core temperature tracking and surface temperature feed-back are...
Centered around the model of ESDDM, a software evolution process model based on evolution behavior interface, and the knowledge of component classification and component retrieval evaluation, this paper furthered previous work by proposing a component reusability evaluation method based on fuzzy mathematics. The method provides an effective way of evaluating the reusable ability of a certain component...
According to “Software processes are software too” proposed by L.Osterweil, we define a software process model with independent functions as a component. This paper focused on the area of component retrieval during the course of a software evolution process which is defined by model of ESDDM. When component retrieving happens, generally a number of similar components are returned as a result set form...
A new CAD software for the sensitivity properties of fiber gratings is reported, which takes the three-layers uniform wave guide as grating guide model. This software uses the transfer matrix method and the coupling mode equation to calculate the spectrum of Bragg grating and long period grating. Based on the Visual C++, the sensitivity properties about temperature, tension, refractive and other sensing...
The reliability assessment of safety-related software systems and components is an issue of primary importance in the nuclear industry, the avionics sector, the military etc. In these areas, the required test effort calculated by the traditional software reliability demonstration testing (SRDT) schemes is too large or too costly to bear. We researched the effects of software test effectiveness on...
Predictable computing is common in embedded signal processing, which has communication characteristics of data independent memory access and long streaming data transfer. This paper presents a streaming network-on-chip (NoC) StreamNet for chip multiprocessor (CMP) platform targeting predictable signal processing. The network is based on circuit-switch and uses a two-level arbitration scheme. The first...
Immersive Web (IW for short) applications such as Second Life and SimCity are increasingly popular among individual users and companies. However, it is difficult to build a hybrid Immersive Web application, because of the different architectures used for building such IW applications. In this paper, we propose a service-oriented framework to support the mashup of heterogeneous IW applications for...
Cloud computing has been attracting much attention since its birth. How to cloudify software systems especially legacy applications in the cloud era is becoming increasingly important. Based on RGPS meta-model framework and International standards-ISO/IEC 19763, an architecture for cloudification of legacy applications is proposed, which consists of three parts: a Web portal, a SaaS service supermarket,...
With the increased number of richness service resources, and maturity of (Service Oriented Architecture) SOA-based solutions, it is critical to develop an innovative software engineering methodology for user-centric and on-demand service oriented computing. This paper proposes the RGPS (Role-Goal-Process-Service) requirements meta-modeling framework for service requirements elicitation, analysis,...
