Currently, Network worm has become one of the major threats to internet, Contrary to the deficiencies in propagation model and defense technologies of Network worm. In order to improve the lack of propagation laws and propagation model of the existing network benign worm, proposed network benign worms model based on a hybrid mechanism, Established the mathematical model of communication, through analysis,...
In the last years one of the main concerns of the software industry has been to reengineer their legacy Web Applications (WAs) to take advantage of the benefits introduced by Rich Internet Applications (RIAs). In this context, Model Driven (MD) Web Engineering approaches have been extended with new modeling primitives to obtain the benefits provided by RIA features. However, during the last decade,...
Social Networking Service is an online service, platform, or site that focuses on building and reflecting of social networks or social relations among people. It's developing by leaps and bounds, and has some notable features in the information economics, such as abundant resources, high user viscosity, interactivity, network externalities, and herding effect and so on. Three possible suitable profit...
Much of our prior knowledge of information systems (IS) usage is based on its acceptance or continuance without understanding whether users are likely to use the IS or not. Prior models of IS usage provide a limited understanding of one's intention to use the IS, given that IS usage or continuance does not necessarily suggest the subsequent use of the IS. Even if people use particular IS, there is...
Motivated by the recent strategy switch of a large software producer, this paper revisits the tradeoffs associated with tolerating illegal distribution of software products. Conventional wisdom is that a higher level of positive network effects justifies a tolerant approach on the part of software producers - because illegal distribution leads to more users, amplifies positive network effects, and...
In this paper, we present an online application service system which includes a SaaS platform server. We applied code generation and metadata model technology in order to serve multiple tenants with a single instance of web based online application.
Aiming at research in mobile phone software supermarket, this paper introduced the definition and industrial chain of mobile phone software supermarket, as well as the comparison between mobile phone software supermarket, physical commodity supermarket and internet supermarket. More importantly, based on the analysis of consumer market and supply market, modeling in game theory was used to demonstrate...
The study of macromolecular protein structures at an atomic resolution is the source of many data and compute intensive challenges, from simulation, to image processing, to model building. We have developed a general platform for the secure deployment of structural biology computational tasks and workflows into a federated grid which maximizes robustness, ease of use, and performance, while minimizing...
WattDepot is an open source, Internet-based, service-oriented framework for collection, storage, analysis, and visualization of energy data. WattDepot differs from other energy management solutions in one or more of the following ways: it is not tied to any specific metering technology; it provides high-level support for meter aggregation and data interpolation; it supports carbon intensity analysis;...
This paper analyzes the concept of components in Software Engineering (SE) through a sociotechnical approach. Based on a ranking of critical elements related to Component-Based SE, a study with experts concludes that components are potential assets in local and collaborative scenarios. This fact motivated an analysis of a value-based component market approach called Brechó-VCM considering its adherence...
Small and Medium Enterprises (SME) represent 90 % of all U.S. Enterprises and 99 % of all European Enterprises and are of high social and economic importance within the U.S. and Europe. Due to their limited resources, SME struggle with structural problems. A possible solution for SME is building networks to act on an extended resource base. Information and Communication Technology (ICT) can act as...
This paper introduces a requirements framework intended to guide novice web developers. The work is based on two earlier studies which found that the requirements phase is not well served in web development methods and that there is no agreed set of requirements from practitioners as to what they would like to see in a web development method. The requirements framework outlined here is developed by...
Service-oriented systems are fast becoming complex nodes in a vast digital, dynamic ecosystem, these systems of systems require the identification and establishment of flexible and spontaneous/opportunistic collaborative activities among various parties. Such sophisticated systems need new engineering approaches able to integrate new functionalities and behaviours into running systems composed by...
The mobile Internet has come to permeate into everyday life. It is expected to accommodate a larger part of the digital economy in the near future. Mobile digital ecosystems have more complicated dynamisms due to the mobile-specific dependencies among their stake-holders. The author presents a framework for mobile digital ecosystems with an entity model, a dynamics model, and an acceptance model....
Phone simulator is a simulation tool running on PC which can test debug phone software. It also provides front graphical user interface (GUI) like the true phone's LCD. Developers can complete the initial development process and test work by phone simulator. This simulator is worked for mobile web application. It is different form traditional phone simulator. Traditional phone simulator only provided...
This paper presents a new electricity market simulator named Internet-Based Power Market Simulator (NetPMS) that has been planned, designed and implemented by the authors in order to study different power market rules before market execution, simulate the behaviors of power market players, train the students and market participants, test the designed agents by researchers and etc. In NetPMS Version...
With the growing number of botnet attacks, the botnet detection is becoming increasingly important for the network security. To enhance the existing botnet detection systems which are short of efficient information collection functions, this paper presents a collaborative information collection model with a new 5-tuple structural mode. In the model, we introduce the static and dynamic roles to meet...
This paper explores the concept of software as a service, which envisages a demand-led software market in which businesses assemble and provide services when needed to address a particular requirement. Comparison between SaaS and its counterparts are described. The design considerations and customer life cycle in SaaS is analyzed. Lastly, the implements for industry commercial prototype are given.
There is often a transient need within enterprises for data cleansing which can be satisfied by offering data cleansing as a transient service. Every time a data cleansing need arises it should be possible to provision hardware, software and staff for accomplishing the task and then dismantling the set up. In this paper we present such a system that uses virtualized hardware and software for data...
