Grid research, rooted in distributed and high performance computing, started in midto-
late 1990s when scientists around the world acknowledged the need to establish an
infrastructure to support their collaborative research on compute and data intensive
experiments. Soon afterwards, national and international research and development
authorities realized the importance of the Grid and gave it a primary position on their
research and development agenda.
Grid computing combines aspects from parallel computing, distributed computing and data management,
and has been playing an important role in pushing forward the state-of-the-art in computer
science and information technologies. There is considerable interest in Grid computing
at present, with a significant number of Grid projects being launched across the world.
From the standpoint of the average user, today’s computer networks are extremely primitive compared to other networks. While the national power, transportation, and telecommunications networks have evolved to their present state of sophistication and ease of use, computer networks are at an early stage in their evolutionary process. Eventually, users will be unaware that they are using any computer but the one on their desk, because it will have the capability to reach out across the national network and obtain whatever computational resources that are necessary...
In this chapter, we discuss the development, architecture, and functionality of the National Partnership for Advanced Computational Infrastructure NPACI Grid Portals project. The emphasis of this paper is on the NPACI Grid Portal Toolkit (GridPort); we also discuss several Grid portals built using GridPort including the NPACI HotPage.
Digital convergence between audiovisual media, high-speed networks and
smart devices is a reality. Multimedia informatics is a key enabling technology
in this process. It helps make media content more directly manageable
by computers, in an age where new information stored on paper, film, magnetic and
optical media is reckoned to double every three years.
What will be the benefits? Digital convergence presents new opportunities for businesses
to unlock new markets, and for public bodies to improve the way they work.
This study to develop AQ pollutant datasets for each of the constituent countries of the UK has been commissioned by Defra in order to better inform energy and environmental policy-makers within the Devolved Administrations in their pursuit of objectives set by the Air Quality Strategy for England, Scotland, Wales and Northern Ireland (AQS for ESWNI). These objectives also contribute to the UK’s targets as a whole in terms of meeting both national and international targets on both local and transboundary air pollution....
“The problems that face our world are so complex and difficult that we
will need all the talent available to solve them.” We wrote those words in
the preface of our first book, A Woman’s Place is in the Boardroom, in
2005, and reiterated them in the second, A Woman’s Place is in the Boardroom:
Exploring privacy risks in information networks is analysing the dangers and
hazards that are related to personal information about users of a network. It is
about investigating the dynamics and complexities of a setting where humans are
served by technology in order to exploit the network for their own good. In the
information network, malicious activities are motivated by commercial factors in
that the attacks to privacy are happening, not in the name of national security, but
in the name of the free market together with technological advancements.
By converting wind energy into electricity,windturbines reduce the environmental impact of powergeneration.Wind energy is currently the mostdeveloped of a number of renewable energytechnologies,with more than 1,000 wind turbinesalready operating across the UK,producing around one quarter of one percent of the country’s energy.Wind turbines can be deployed individually,to power a single site or installation,but are most commonlygrouped together as ‘wind farms’to provide power to the national grid.
We know how to fix the problem of childhood hunger,
and we have an opportunity now to build a prosperous
future for us all by doing that. Over the past century
Americans have built marvelous networks and systems
of infrastructure that are necessary to our economy
and quality of life. Through creativity, inventiveness,
ingenuity and hard work we have made our country a
model of success in many areas. For example, we have
built a national power grid, telecommunication systems,
water systems, transportation systems, and internet
systems that are peerless, to list just a few.
A special thank you to Hope Steele for her superb editing work and Neil Weinberg for his excellent graphic design and layout. The terms country and nation as used in this report do not in all cases refer to a territorial entity that is a state as understood by international law and practice. The terms cover well-defined, geographically self-contained economic areas that may not be states but for which statistical data are maintained on a separate and independent basis.
Bioinformatics is at a crossroads. We work in a field that is changing
every day, increasingly moving from specific solutions created by single
researchers working alone or in small groups to larger, often
geographically dispersed programs enabled by collaborative computing
and open software. This book represents an important development, giving
the reader an opportunity to discover how the use of open and reusable
Java code can solve large bioinformatics problems in a software
engineered and robust way.
The Swiss work was based on a provisional national PM10 emission inventory. It was first
disaggregated to a km2
grid. Dispersion functions for primary PM10 emission were defined in an
empirical dispersion model which was used to calculate the concentration of primary PM10. The
contribution of secondary particles was modelled by using simple relationships between precursor and
particle concentration. The long-range transported fraction was taken from European scale models.
The PM10 fractions were then summed to create the PM10 map.
