Internet of Things Cloud: Architecture and Implementation
The Internet of Things (IoT), which enables common objects to be intelligent
and interactive, is considered the next evolution of the Internet. Its
pervasiveness and abilities to collect and analyze data which can be converted
into information have motivated a plethora of IoT applications. For the
successful deployment and management of these applications, cloud computing
techniques are indispensable since they provide high computational capabilities
as well as large storage capacity. This paper aims at providing insights about
the architecture, implementation and performance of the IoT cloud. Several
potential application scenarios of IoT cloud are studied, and an architecture
is discussed regarding the functionality of each component. Moreover, the
implementation details of the IoT cloud are presented along with the services
that it offers. The main contributions of this paper lie in the combination of
the Hypertext Transfer Protocol (HTTP) and Message Queuing Telemetry Transport
(MQTT) servers to offer IoT services in the architecture of the IoT cloud with
various techniques to guarantee high performance. Finally, experimental results
are given in order to demonstrate the service capabilities of the IoT cloud
under certain conditions.Comment: 19pages, 4figures, IEEE Communications Magazin
The role of intellectual property rights in information and communication technologies
The paper starts by recapitulating the basic arguments provided by economic theory to explain the existence of the patent system. The paper then concentrates on the three important ICT industries viz., telecommunication equipment, computer hardware and semiconductor industries. The issues covered in the discussion on these industries are the technological characteristics; market structure and technology transfer experiences of selected developing countries. Even though there are some differences in these industries, what come out clearly are some similarities. These similarities pertain to concentration by firm as well as country; rapid technological changes; existence of scale economies; rising minimum efficient levels of production; entry barriers to the industries both financial and technological etc. Bresnahan, Stern and Trajtenbert [1997] show that in the computer PC market brand name and being on technological frontier help the firm in appropriating inventions. Taylor and Silberston [1973] observe that in electronics while patents by themselves are not important method of appropriation, it encourages firms to accumulate patents so that they can have an advantage in cross-licensing agreements. This finding was reiterated by Hall and Ham [1999] for semiconductor industry. They name this phenomenon "patent portfolio race". The paper briefly touches upon the issues pertaining to Internet and the problems it raises for copyright; protection of computer software and the discussion on a sui generis protection for databases. The paper concludes that the role of IPRs in ICT seems to be marginal and as prices are falling it does not seem to be attracting negative attention.Intellectual property rights, patents, information and communication technologies
MonetDB: Two Decades of Research in Column-oriented Database Architectures
MonetDB is a state-of-the-art open-source column-store database management system targeting applications in need for analytics over large collections of data. MonetDB is actively used nowadays in
health care, in telecommunications as well as in scientiïŹc databases and in data management research,
accumulating on average more than 10,000 downloads on a monthly basis. This paper gives a brief
overview of the MonetDB technology as it developed over the past two decades and the main research
highlights which drive the current MonetDB design and form the basis for its future evolution

Building knowledge-based economies: research projects in knowledge management and knowledge transfer
Small and medium-sized enterprises (SMEs) are viewed as the growth engines of the new knowledgebased
economy. This new economic growth model differs from the old in significant ways, many of which
are related to the knowledge base that will be required by the SMEs. Based upon prior research a set of
factors important to the success of SMEs in a knowledge-based economy is described. Focusing on those
factors related to the knowledge base, the paper concludes with a set of research questions and brief
descriptions of three research projects on knowledge management and knowledge transfer
Technological national learning in France : from minitel to internet
In France, the development of the Internet has been influenced by the evolution of the inherited information technology. France had many of the elements needed for the Internet to flourish: excellent engineering schools, participation of scientists and academic researchers in data networks, financial markets with venture capital companies, supportive government, and high incomes. Thus, France had many of the components that constitute the American, or even the Silicon Valley, model. And yet, the internet economy did not begin until some years after the United States, Sweden, and the United Kingdom. Many have argued that the monopoly of France Telecom slowed the Internet's development in France. In this chapter, we shall show that it was instead France's early lead in electronic commerce that hindered this development.internet;politique économique;développement;technologies de l'information de la communication;évolution de la structure de marché;frontiÚre public/privé
Factors shaping the evolution of electronic documentation systems
The main goal is to prepare the space station technical and managerial structure for likely changes in the creation, capture, transfer, and utilization of knowledge. By anticipating advances, the design of Space Station Project (SSP) information systems can be tailored to facilitate a progression of increasingly sophisticated strategies as the space station evolves. Future generations of advanced information systems will use increases in power to deliver environmentally meaningful, contextually targeted, interconnected data (knowledge). The concept of a Knowledge Base Management System is emerging when the problem is focused on how information systems can perform such a conversion of raw data. Such a system would include traditional management functions for large space databases. Added artificial intelligence features might encompass co-existing knowledge representation schemes; effective control structures for deductive, plausible, and inductive reasoning; means for knowledge acquisition, refinement, and validation; explanation facilities; and dynamic human intervention. The major areas covered include: alternative knowledge representation approaches; advanced user interface capabilities; computer-supported cooperative work; the evolution of information system hardware; standardization, compatibility, and connectivity; and organizational impacts of information intensive environments
