Graph databases are taking place in many different applications: smart city, smart cloud, smart education, etc. In most cases, the applications imply the creation of ontologies and the integration of a large set of knowledge to build a knowledge base as an RDF KB store, with ontologies, static data, historical data and real time data. Most of the RDF stores are endowed of inferential engines th...

With the development of Internet of things (IoT), there are many smart city projects for improving urban services recent years. Community is a basic subunit of a city, smart community involves those important affairs which most directly related to unban services in a smart city overall planning. Based on the dualism of information architecture and business model by Kuk and Janssen (2011), the s...

Smart environments integrate Information and Communication Technologies (ICT) into devices, vehicles, buildings and cities to offer an increased quality of life, energy efficiency and economical sustainability. In this perspective, the individual has a core role and so has networking, which enables such entities to cooperate. However, the huge amount of sensitive data, social aspects and the mi...

The main goals of smart metering are the reduction of costs, energy and CO2 by the provision of actual metering information to the providers and the customer. They allow for flexible possibilities to influence the customers’ energy consumption behavior and to adapt dynamically the power generation and distribution to the requested energy by smart grids. Metering devices are under control of gov...

Understanding the stakeholder’s needs, particularly the end-user’s need is important when designing and developing a critical infrastructure like power grid. Smart metering systems are considered as a vital element in grid modernisation projects. It provides the utility with a range of opportunities to improve their business. The benefits to other market parties are also clear. But the resident...

Smart environments integrate a multitude of different device ensembles and aim to facilitate proactive assistance in multi-display scenarios. However, the integration of existing software, especially visualization systems, to take advantage of these novel capabilities is still a challenging task. In this paper we present a smart view management concept for an integration that combines and displ...

The smart card has a microprocessor or a memory chip embedded in a plastic card. It has been in wide use in Europe and Japan for payment, entry into buildings and computer systems, and storage and access of special types of information. In the US, despite efforts by the credit card industry, the smart card has not been nearly as widely adopted as in Europe and Japan. In this article, we will re...
