In recent years, service-oriented architectures (SOA) have emerged as the main solution for the integration of legacy systems with new technologies in the enterprise world. A service is usually governed by a client service contract (CSC) that specifies, among other requirements, the rate at which a service should be accessed, and limits it to no more than a number of service requests during an observation...
Software engineering and its constant evolution bring new concepts, new technologies and new devices. It requires big efforts, skills and resources to acquire in depth knowledge of all the parts that are necessary for building applications professional and efficiently today. Many small technological companies and freelance developers have serious doubts about how to manage a project, where to start...
in this paper, we propose a biofeedback system that employs a Cloud-Oriented Architecture (COA) for the dissemination of biofeedback information and services. The architecture provides the software infrastructure to build biofeedback applications that maintain the user's well-being by monitoring a number of physiological parameters and generate the appropriate feedback. Consequently, the architecture...
Federal Emergency Management Agency (FEMA) and the Department of Homeland Security, Science and Technology Directorate (DHS S&T) and are working together, in collaboration with MIT Lincoln Laboratory (MIT LL) to modernize and transform the existing Homeland Security Exercise and Evaluation Program (HSEEP) Toolkit into an agile enterprise platform for integrating existing and future capabilities...
An inter-system adapter design is described which links the web service based DR NEP and WebSimP simulation platforms. The adapter enables the PSS Sincal electrical simulator to share results with the DR NEP which coordinates the data exchange among interdependent simulators. In this paper, we describe an adapter which supports decision makers involved in natural crisis management by calculating constraints...
We present a platform for Intra and Inter Domain Social Information Service (IIDSIS), able to identify, analyse and exploit (complex) relationships emerging from the use of multiple pervasive Internet services, offered in different domains. The computed social information is offered as a service to the domain applications, both to improve their effectiveness and to increase end-users' awareness of...
The goal of the system framework (e-Hospice+) is to create an Electronic Health Record (EHR) System which can be used by medical clinic to provide special healthcare services to hospice care patients. The framework allows both web-based and mobile-based healthcare application frameworks to be created to satisfy a variety of needs of clinical personnel. The web-based applications are performed at the...
The increasing use of Web services as well as the growing interest lent to Cloud computing technology and its capacity of calculation, storage and Cloud services, impose today that the traditional mechanisms of discovery must be re-examined. This specificity of discovery over the cloud led us to propose a new approach based on mobile agents dedicated to Web services discovery. More accurately, we...
With the development of the Internet, Web Services technology has gradually become the development direction of the e-business, e-government and other fields, and the corresponding security mechanism has received unprecedented attention, while how to design an integrated architecture to enhance web services security remains a problem very difficult to tackle with, and there are no good solutions to...
Web services are widely known as the building blocks of typical service oriented applications. The performance of such an application system is mainly dependent on that of component web services. Thus the effective load testing of web services is of great importance to understand and improve the performance of a service oriented system. However, existing Web Service load testing tools ignore the real...
The software systems running in an enterprise consist of countless components, having complex dependencies, are hosted on physical or virtualized environments, and are scattered across the technical infrastructure of an enterprise, ranging from on-premise data centers up to public cloud deployments. The resulting topology of the current IT landscape of an enterprise is often extremely complex. We...
In this article we present a 3-layer architecture (MAPIS3) that facilitates the integration of adaptive characteristics in an IMS-LD based computer-supported collaborative learning scenario (CSCL script), by making use of external and independent software components. The proposed architecture introduces a mediator component (MC) as a key element which mediates the communication of IMS-LD based representations...
An ATE software or test executive must perform a variety of tasks in addition to simply sequencing and running functional tests on the device under test (DUT). These tasks include prompting the test operator for a serial number and displaying test results, logging the results of the tests to a report, test system calibration and self-tests, and more.
The definition of network management interface is generally divided into three phases, requirements, analysis and design. In analysis phase, UML is used as the modeling language to present technology independent models, and these models can be mapped into multiple technology specific models. With the development of Web Services applied in network management domain, it is required to define Web Services-based...
This paper investigates into the transaction management of mobile web services, which is crucial to maintaining execution correctness of services and consistency of their underlying data. We propose a relaxed set of transaction correctness criteria, called Sacred (Semantic Atomicity, Consistency, Resiliency, Durability) and design protocols for enforcing these criteria in the execution of transactions...
Bioinformatics is an emerging field with seemingly limitless possibilities for advances in numerous scientific research and applications domains. In this paper, we summaries the explosive cutting-edge acceleration engines for the emerging short read mapping problems. What's more, we propose a novel Cloud based web service solution to the short read mapping problem in DNA sequencing, which greatly...
Service-oriented architecture (SOA) is a system architecture model consisting of standardized components such as web services. Its purpose is to provide corporations a flexible integrated interface that can be used repeatedly. Past application systems, including expert systems, were unable to meet the requirement of reusability. Web services wipe out the barriers in system development and help system...
Cloud computing is the current trend for business web applications which provide computing related services to the users. Cloud computing locates resources, distribute tasks and collects data from appropriate servers from a cluster of networked computers. Major advantages of the cloud computing include reduced cost of operation and maintenance compared to the usage of resources. It also makes it easy...
In order to fully exploit the potential of optimization algorithms for energy savings in factory automation settings, it is needed to bring together engineers that have knowledge of signal processing algorithms with shop floor engineers that are experienced with real manufacturing processes and factory automation settings. This paper presents an open database storing energy-relevant data from a multi-robot...
We propose in this paper a new approach for conformance testing of WS-BPEL compositions under various load conditions. It is based on Timed Automata as model for testing WS-BPEL implementations, a distributed testing framework that automatically generates and executes parallel tests online, and an algorithm for online test generation and execution. We also implemented a part of our solution in the...
