Paper presents a solution providing OPC UA connectivity from a common web user using web technologies. Integration of OPC UA with the web may represent an important contribution to enhance its interoperability, allowing integration with web applications, IoT and WoT. The main difference with the solutions available in literature is that user may have no knowledge of OPC UA standard. A web-based platform...
The paper presents a web-based platform able to offer access to one or more OPC UA Servers. The proposed platform may be used by web-users to exchange data with OPC UA Server without any knowledge of the standard. The software solution described in the paper is available on GitHub.
Hypertension is a chronic disease characterized by high blood pressure levels. Lack of adherence to the treatment of hypertension is a growing concern among health professionals. For this, m-Health solutions are increasingly evident, since they can automate processes and facilitate the inclusion of the patient's health conditions in a practical way and in any place, allowing the health professional...
Accurate capacity measurement of Internet services is critical to ensure high-performing production computing environments. In this work, we present our solution of performing accurate capacity measurement. Referred to as “LiveRedliner”, it uses live traffic in production environments to drive the measurement, hence avoiding many pitfalls that prevent capacity measurement from obtaining accurate values...
In the existing service selection models, there is not a good one for SaaS system. In view of the characteristics of multi-tenant in SaaS system and the perspective of ensuring the tenants' enthusiasm, this paper puts forward a QoS-constrained service discovery model based on intelligent agent, as well as a service selection algorithm based on tenant level. Extensive experiments have been conducted...
HTTP(S) has become the main means to access the Internet. The web is a tangle, with (i) multiple services and applications co-located on the same infrastructure and (ii) several websites, services and applications embedding objects from CDN, ads and tracking platforms. Traditional solutions for traffic classification and metering fall short in providing visibility in users' activities. Service providers...
The identification of the services that generate traffic is crucial for ISPs and companies to plan and monitor the network. The widespread deployment of encryption and the convergence of the web services towards HTTP/HTTPS challenge traditional classification techniques. Algorithms to classify traffic are left with little information, such as server IP addresses, flow characteristics and queries performed...
The people who use inner city public transportation vehicles want to get information about the current status of the public transportation vehicles and they want to know the travel time of the vehicles both while travelling and waiting at the bus stops. In this study, a smart bus stop-passenger information system was developed in order to enable administers effectively monitor the public transportation...
The Repository of services (web-applications with a unified interface) is proposed for patient care (care services), for planning and carrying out of treatment (treatment services) and to ensure the functioning the entire system (management services). Treatment of diabetes becomes personalized and customized because it is possible to build and adjust their treatment plan and workflow by selecting...
Internet application workloads typically vary over time, periods of low demand alternate with spikes which, if not properly handled, can saturate the allocated infrastructure and violate Service Level Agreements. In this work, we leverage the usage patterns associated with the different customers of an Internet application to make tailored workload predictions. These workload predictions are then...
Performing functionality testing in serviceoriented architectures is not a trivial task. The difficulty is especially the large number of components that may be present in a SOA such as brokers, providers, service registries, clients, monitoring tools, data storage tools, etc. Thus, in order to facilitate the process of conducting functional testing and capacity planning in service-oriented systems,...
Network-based cloud computing is considered to be an emerging model of business computing, which maintains configurable resources such as processors, networks, storage, operating systems, database, and servers. One of the most successful paradigms that can be configured over the cloud is the Service oriented Architecture (SoA) environment, which provides a layered architecture for organising software...
This paper focuses on analysis of a nuclear power group to headquartered brand as the core, to surrounding radiation entire range of video monitoring system of distribution and the management current situation, according to the system's architecture features and user requirements, and based on the use of WPF and Web Service technology, it had proposed and constructed a new integration method and integration...
Remote vehicle monitoring system keeps track of vehicle and also monitor the fleet level of the vehicle status. Here two problems are dealt with. First one is the anywhere any time monitoring of the vehicle status cannot be done through manual monitoring and the second one is the system behavior change according to user changes. The novelty of the proposed approach is twofold. First our proposal allows...
This paper presents a characterization of Amazon's Web Services (AWS), the most prominent cloud provider that offers computing, storage, and content delivery platforms. Leveraging passive measurements, we explore the EC2, S3 and CloudFront AWS services to unveil their infrastructure, the pervasiveness of content they host, and their traffic allocation policies. Measurements reveal that most of the...
Developers often rely on penetration testing tools to detect vulnerabilities in web services, although frequently without really knowing their effectiveness. In fact, the lack of information on the internal state of the tested services and the complexity and variability of the responses analyzed, limits the effectiveness of such technique, highlighting the importance of evaluating and improving existing...
This paper presents two implementations of condition monitoring of significant information in a typical machine utilized in the pulp and paper industry, a circuit oil lubrication system. The two discussed alternatives confront a traditional centralized monitoring approach against a Web Service based approach. Advantages and disadvantages of one choice over the other are considered. Both solutions...
Wireless sensor networks (WSNs) belong to emerging technologies where network devices can interact with the surrounding environment by sensing physical parameters. Recently, with the dissemination of mobile devices to Internet connectivity, users can interact with sensor networks and collect environmental data, anytime, anywhere using user-friendly mobile applications. Following the Internet of Things...
Western Australia's economy is largely driven by the extraction and processing industry. Caused by inhospitable climate and living conditions in the remote regions, where the vast majority of the natural resources are found, housing needs for personnel are both difficult and costly to meet. The provision of energy accounts for a big part of this since it often requires the transportation of large...
Shopping cart manipulations are a prime example of web services exhibiting stateful behaviour. The Beep Store is a web service synthesizing past work on the study and formalization of stateful interface constraints, and presenting many of the characteristics found in real-world web services, such as Amazon's and PayPal shopping carts.
