This paper presents monitoring as a service for networked medical cyber-physical systems in the operating room based on the recent IEEE 11073 standards for interoperable medical device communication. Runtime Verification techniques are used to allow for a formal specification and verification. Based on the specification so called monitors are automatically synthesized. At runtime, the monitors observe...
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...
Agricultural drought greatly impacts the crop yield. Monitoring agricultural drought can deliver critical information to farmers on when, where and how much to irrigate. However, precisely monitoring which requires many kinds of data sources and data fusion and mining is still a huge challenge for scientists. In recent years, many data sources like remote sensed hyperspectral images are released online...
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.
This paper proposes a system integrating device manager, IoT Solution, and Business Process Model and Notation (BPMN) tools. With these tools, domain expert can draw the process with specifying how to connect devices all together. Moreover, domain expert can specify what kind of device is needed instead of explicitly specifying which device is needed, which addresses the IoT feature, mobility. This...
Conventional electricity grids evolve into smart grids by incorporating Information and Communications Technology (ICT) services. These services are meant to provide finegrained monitoring of the grid and pervasive control over its components. The ultimate goal is to avoid major failures and blackouts and to improve the efficiency of energy generation, transmission, and consumption. Smart grids support...
The Pub/Sub, short for Publish-Subscribe, is a flexible mechanism perferred by many users who'd like to passively know the changes of situation. Once a new message is published by a provider, all the subscribers to the specific kind of messages will receive the message and make corresponding responses. In agricultural crop monitoring, such mechanism is very helpful in enhancing the efficiency of message...
In recent years, there has been an increase in the desire by citizens to participate in public decision-making. This has led to the emergence of numerous participatory processes across the world. A participatory process may be described as a set of participatory common tasks satisfying certain constraints. The design of such processes may become a complex task for inexperienced individuals. We develop...
High performance platforms composed of commodity computing resources, such as grids and peer-to-peer systems, have greatly evolved and assumed an important role in the last decade. Nevertheless, their wide commercial use still depends on the establishment of an effective quality of service (QoS) infrastructure in those environments. For this reason, a variety of proposals have recently emerged in...
DIES system for designing and improving enterprise business scenarios is proposed. Such scenarios are executed and monitored in an SOA environment. Many metrics are gathered, and strong/weak aspects are pointed out. DIES allows the improvement of a scenario's performance, quality, and usability. Due to technology-agnostic API the system supports any extensible business scenario technology, and it...
Electronic collaboration over the Internet between business partners appear to be converging toward well-established types of message exchange patterns that involve both user-defined standards and infrastructure standards. At the same time, the notion of event is increasingly promoted for asynchronous communication and coordination in SOA systems. In collaboration between partners or between components...

Web services define standard interfaces those provide good solution for enterprise integration. Recently, many researches focus on creating management standards to manage Web services. Web Services Distributed Management (WSDM) is one of the industry standards. However, to implement the WSDM interfaces needs to understand server Web service standards. It increases the complexity and difficulty to...
The paper presents Software as a Service approach to the real-time satellite imagery dissemination. Proposed system architecture comprises 4 logical units, namely the data acquisition, management, coverage server and client modules which are organized in an linear layout. Web Coverage Service (WCS) query protocol is extensively utilized as an interface for exchange of data between the modules. The...
Current Web services specification languages like WSDL and OWL-S are only focused on functional description. An important component that is missing from these specifications is the non-functional description such as its quality of service (QoS), cost, availability, etc. A comprehensive service description which provides information on non-functional aspects also is essential for tasks such as service...
Taiwan is located at the collision boundary of the Philippine sea plate and the Eurasian plate. The mountain terrain is precipitous and the region, on the whole, is characterized by fragile rocks and frequent seismic activity. In addition, the concentrated torrential rainfall brought by typhoons cause extensive disasters, debris flow, the most serious disaster caused by torrential rainfall, lead to...
Crop development progress information is critical to decision makings in National Agriculture Statistics Services (NASS) of United State Department of Agriculture (USDA), other federal agencies, and public users. NASS currently compiles and issues the weekly national crop progress report based on crop conditions reported by state and county agricultural officials. The report is point-wise sampled,...
The more learner information is shared across a wide range of heterogeneous applications and tools, the more learner profiles will be relevant, reusable and useful for many systems and environments. This proposal stands on a widely used management standard, and introduces an open and generic learner profile supported by a service-oriented architecture ensuring exchange and reuse of learner information...
Service oriented architecture (SOA) based on Web services is starting to be considered as the technology in the manufacturing environment that will enable an increase agile and collaborative manufacturing capabilities. This paper explores the application of SOA in shop floor automation using device profile for Web services (DPWS) which allows SOA on a device. In this research, orchestration framework...
Efficient Web services (WS) based network monitoring of managed devices is a difficult task due to the relatively big overhead WS impose. In the past we proposed mechanisms to perform distributed monitoring efficiently, minimizing the relevant overhead. Standardization of WS operations is also important in order to achieve interoperability. The WS Resource Framework (WSRF) tries to standardize the...
