The development of service computing technology has triggered the need for organizations to build a service computing system. This system is able to deliver IT services that can meet the challenges and needs of business services. An understanding of the service computing systems engineering life cycle is necessary to model and build the systems. This paper conducts the study of the service computing...
Metal additive manufacturing (AM) processes are very complex and the process parameters required to fabricate quality parts can be very complicated and challenging to determine. For this reason, there is a continuous demand for AM simulations which can assist users to determine optimal process parameters in a timely manner. However, current commercial simulation packages are expensive and not designed...
Integration of hospital information systems (HIS) is an important area and one the basic requirements of hospitals since it increases quality of care and at the same time reduces costs of creating, upgrading, updating and keeping up with technology and healthcare industry standards and information technology. Cloud computing with features like multitenancy, massive scalability, elasticity, pay as...
Software as a Service (SaaS) is an on-demand software delivery model, where the software and its related data are placed at remote location and are accessed as a web based service using a thin client such as web browser over the Internet. The salient features of SaaS includes low startup cost, easy provisioning at the time of need, shorter release cycle, easy maintenance, cost saving on maintenance...
Enterprise Service Oriented Architecture (ESOA) is taking centre stage in the transformation journey of large corporations due to its extravagant promise of dynamic composition of applications from services. As the penetration deepens, an interesting pattern emerges: SOA becomes the new silver bullet; initiatives are pushed to run under the SOA banner, and more and more fail to deliver the promise...
Cloud computing is one of the most popular technology recent years due to its ability to deliver every IT resource in the internet as a service. no matter industry, academia, or users, they all have greatly interest in cloud computing. Many IT giants such as Google, Amazon, Microsoft, and IBM have successfully applied their Clouds with different technologies and architectures. at present, the common...
Cloud computing is Internet-based computing, and it takes every IT resource in the internet as a service to users, such as hardware services, infrastructure services, platform services, software services, storage services and so on. While SOA as a service oriented architecture, it's a software designing model and method. SOA can integrate well-defined services to a new solution. So, cloud computing...
As popular web applications, web services can provide very flexible application integration taking advantage of existing Internet protocols and open standards. However, there are a few stubborn problems which exist in its architectures, for example, security. Especially in distributed services environment, trust which is a proved way to resolve security problem of web service is crucial to service...
Under the circumstance of earth observation data booming, it is important to develop an intelligent and automatic processing method for the geospatial data. Currently the OGC web services standard offer unique interfaces for the geospatial data planning, accessing, processing and publishing. This paper focuses on the Web processing model building and implementing — how to organize the distributed...
As Cloud Computing has become more and morepopular, various Cloud Computing architectures or infrastructurehave been defined, given their specific circumstances forthe applications. However, to effectively achieve the potentialof cloud computing, there is need for the definition of systemarchitecture of the software systems involved in the deliveryof cloud computing, so that it can be used as a reference...
In order to obtain an advantageous position in the protean global market, the modern manufacturing enterprises require a flexible and self-adaptive foundation which is capable of dynamically exploiting manufacturing resources and services distributed across the network. In this paper, the cloud manufacturing vision (GetCM) is introduced to provide the on-demand architecture with reliability, flexibility...
Service Oriented Architecture (SOA) refers to an architectural paradigm that describes how organizations, people and systems provide and use services to achieve their goals. Moreover, with the evolution of SOA, the focus in software development has shifted from applications to reusable services. Besides, reuse in SOA has more focused on service composition rather than reuse of existing implementations...
The paper introduces a novel architecture for industrial automation which addresses both the optimization of manufacturing processes and the ability to react to changes in the market demand. The architecture consists of three main components: a mixed-integer-programming level, a two-layered web service level, and an OPC UA server. The web service layer acts as backbone of the architecture and assures...
In recent years, there has been a growing interest in cloud technologies. Using current cloud solutions, it is however difficult to create customizable multi-tenant applications, especially if the application must support varying Quality of Service (QoS) guarantees. Software Product Line Engineering (SPLE) and feature modeling techniques are commonly used to address these issues in non-cloud applications,...
Modeling and verification of Web services composition have been presented in this paper. In modeling we have used Calculus of Communicating Systems(CCS) for implementation and modal μ-calculus for property specification. Models have been verified using Concurrency Workbench of the New-Century(CWB-NC). CCS includes primitives for describing parallel composition, choice between actions and scope restriction.
In 2007, the National Institutes of Health (NIH) funded the Physical Activity and Location Measurement System (PALMS) project at the University of California, San Diego. Its mission is to advance exposure biology research by developing new methods of physical activity data capture and analysis from a geospatial perspective. A key early insight was that while exposure biology investigators often employ...
Modern organizations increasingly depend heavily on information stored and processed in distributed, heterogeneous data sources and services to make critical, high-value decisions. Service-oriented systems are dynamic in nature and are becoming ever more complex systems of systems. In such systems, knowing how data was derived is of significant importance in determining its validity and reliability...
Cloud computing technology is put on more and more attentions for decreasing the IT budget of small and median enterprises. But the heterogeneous, distributed and dynamic properties of current SaaS software hamper the creations of one universal SaaS platform to securely integrate the often-used software for the enterprise. In this paper, we propose our public SaaS platform based on SOA architecture,...
Bayesian network is an effective tool to represent the probabilistic relationships among variables and do probabilistic inference. The algorithms of both network training and reasoning are complex and diverse. There exists no algorithm appropriate to all kinds of dataset, so it is improper to deploy all the algorithms of Bayesian network on one server especially when providing service in a distributed...
Simulation software is a special category of software that is used by researchers or field experts. As the Service-Oriented Architecture gains its popularity, it is desirable to make simulation software, which originally is accessible only on a single machine, as a service that can be accessed by researchers and field experts over the Internet. Towards this goal, this paper provides a specification...
