With the explosive growth of Web services on the Internet, Quality-of-Service-based (QoS) service selection is becoming an important issue of service-oriented computing. The QoS values of services to current users are all supposed to be known in the previous works, while lots of them are not known in reality. In order to predict the missing data, many approaches have been employed in recent years...
This paper describes an intelligent insulating shipping container (IISC) and the supporting backend for cold-chain logistics. Each IISC can monitor the interior temperature of the container during shipping of temperature-sensitive items and alerts the deliverer wirelessly via a Bluetooth-Smart (also called Bluetooth 4.0 Low Energy, BLE) connection on their smartmobile without infrastructure or dongle...
A key indicator for sustainable application development is reusability of components. Current research on application development aims to combine Services from the Web based on a description given by the developer. So, in many cases there should be no need to develop new applications from scratch. There is at least some sub-functionality provided somewhere which avoids the reinvention of the wheel...
With cloud computing becoming more than a buzz word and other modern IT service solutions catching on in enterprise environments, decision support models lag behind. Modern IT service landscapes with their loosely coupled services, short-term contracting and on-demand service provisioning have added an additional layer of complexity in service sourcing decision processes and thus require a new form...
Service-Oriented Architecture (SOA) is a software paradigm with a uniform means to offer, discover, compose services' capabilities to meet desired effects with measurable performance expectations. While most of today's SOA tools support service process compositions by considering only functional attributes, additional support for composing service processes by non-functional attribute is needed. In...
Quality-of-Service (QoS) is a fundamental element in Service-Oriented Computing (SOC) domain. Sufficient and accurate QoS information benefits to the parts not just in-depth analysis in theory but also in system deployments in practice. Studies of predicting missing QoS values is gaining important as an essential step to fast support operations in both academia and industry. Although there are a number...
Over the last decades, graphics processing units have developed from special-purpose graphics accelerators to general-purpose massively parallel co-processors. In recent years they gained increased traction in high performance computing, as they provide superior computational performance in terms of runtime and energy consumption for a wide range of problems. In this survey, we review their employment...
Data- and artifact-centric business processes are gaining momentum due to their ability of explicitly capturing the interplay between the process control-flow and the manipulated data. In this paper, we rely on the framework of Data-Centric Dynamic Systems (DCDSs), which has been recently introduced for the formal specification and verification of data-centric processes, and we discuss how it can...
Service Composition is an essential part of Service Oriented Architectures (SOA). The number of available alternatives for web services offering similar functional characteristics opens opportunities to maximise compositions based on criteria embedded into the Quality of Service (QoS). These non-functional criteria may be numerous and diverse, and arise from various constraints, making composition...
The advances of pervasive technology offer new standards for user comfort by adding intelligence to ubiquitous home and office appliances. With intelligence being the core of some newly constructed buildings, it is important to design a scalable, robust, context-aware architecture, which not only has enough longevity and evolving capabilities to sustain itself over the building's lifetime, but also...
The Internet of Things (IoT) aims to integrate the digital world of the Internet with our encompassing physical world. However, existing IoT lacks to provide considerate services, meaning that sensors dynamically "collaborate" to provide context-aware federated sensor data. This paper reports our on-going work developing a sensor service federation and provisioning infrastructure. A novel...
A pattern recognition (PR) system is addressed for nonintrusive appliance load monitoring. For the effective recognition of two home appliances (specifically, an electric iron and a cook top), we consider a novel feature extraction method employing higher order moments of power signals from the appliances. Through simulation results, we have confirmed that the PR system with the features from the...
Business processes can benefit from the external knowledge widely available in the web in terms of open services. Traditional centralized approaches to services orchestration are subject to serious limitations for orchestrating processes with the wider range of open services. Dealing with these limitations calls for decentralized approaches. However, decentralized approaches are themselves faced with...
