A Virtual Private Network (VPN) is defined loosely as a network in which customer
connectivity among multiple sites is deployed on a shared infrastructure with the same
access or security policies as a private network. With the recent advent of marketing
activities surrounding the term VPNs, from new technologies supporting VPNs to a flurry
of VPN-enabled products and services, you might think that the VPN concept is a major
technology throughput. However, as is often the case, VPN is a concept that is more than
10-years old and is well known in the service provider market space....
The increased online presence of customers is making it imperative for traditional brick-and-mortar banks to establish themselves in the virtual space. Banks are moving toward virtualization by offering services on the internet and by mobile phone. The challenge today is to offer integrated financial services to customers across all delivery channels, introduce differentiated products to respond to and exceed customer expectations, and improve return on investment in a highly mature and competitive landscape.
The chapters in this book reflect leading edge ideas, reflections and observations. Even
though the modern era of sleep research evolved from Aserinksky’s observations of
rapid eye movements in the sleep of babies, most work is nonetheless done in adults.
There is much less formal work done in youngsters and virtually none in utero and
pregnancy itself is virtually unexplored. So, Dr Miller et al’s chapter reviewing sleep in
pregnancy is particularly welcome as it incorporates current thinking in how disordered
sleep impacts other adult pathological processes.
In this book I explore public and professional writing produced through
diverse modes and genres, for example, corporate and political documents,
websites and emails. I also investigate the processes of developing and
the impacts of reading such writing in various contexts, for example,
within and between workplaces, in the corporate, public and political
spheres, and in physical and virtual spaces.
Education has become the number one demanded commodity for social and economic transformation for both developing and developed economies. Thus the number of persons going and returning to school has become too big to be handled by existing brick and mortar learning institutions. Besides, the majority of lifelong learners do not have the time to become full-time students. Distance education is becoming the solution to the aforementioned challenges. It has been defined as the mode of study where the learner is separated in time and space from the institution and tutors providing the tuition....
This report provides information and recommendations on the results of the Coordinated
Street Furniture Program Request for Proposals No. 9103-06-7316. Staff are seeking
City Council’s authority to enter into negotiations with the Vendor best satisfying the
requirements of the RFP, Astral Media Outdoor LP, to finalize contract provisions,
incorporate technical and design refinements to the recommended family of street
furniture; and enter an Agreement with the recommended Vendor.
Advances in the capabilities of technologies applicable to
distributed networking, telecommunications, multi-user
computer applications, and interactive virtual reality are
creating opportunities for users in the same or separate locations
to engage in interdependent, cooperative activities
using a common computer-based environment.
The Internet is a remarkable phenomenon. Essentially, it is just a large number of computers connected together in
such a way that communication between them is both reliable and fast. Phrased in this way, it is wholly unremarkable.
But the Internet is also the people who use it, to communicate and to share information, even to build relationships
and communities. It's a culture that has grown within a virtual space, and that has permeated many aspects of our
The state-of-the-art Belk Library features the latest in information technology and is
located at the center of campus, convenient to all graduate classrooms. It is uniquely
designed to integrate print, electronic and audiovisual resources, with an extensive
program of research, tutoring and technical support available during all hours of
operation to assist students and faculty. More than 200 Macintosh and Windows desktop
computers and wireless laptop computers offer access to the online catalog and the
Some sites are presented as virtual cities where digital individuals live their lives parallel to the
‘real ones’, some promote the images of real cities being an increasingly important place
marketing tool. Especially the most iconic global tourist cities provide images that aim to give to
these material places new meaning in the virtual space. Apart from being part of the virtual realm,
webcams can, indeed, create ‘real interest on a real place’ adding to them “a whole new stratum
of cultural space” (Campanella, 2004: 59).

Vertical relationships between government and society still do exist, but almost
everywhere they are becoming the exception, rather than the rule. During the last
two decades developments in public administration have tended to replace
hierarchies. Both in and between organisations, by all kinds of - more or less
horizontal - networks, through which the governmental authorities have realised
their dependency on the other actors in society.
This chapter describes the development of a humanoid robotic language and the creation of
a virtual reality system for the simulation of humanoid robots. In this chapter we propose a
description language for specifying motions for humanoid robots and for allowing
humanoid robots to acquire motor skills. Locomotion greatly increases our ability to interact
with our environments, which in turn increases our mental abilities. This principle also
applies to humanoid robots.

Given a holomorphic vector bundle E over a compact K¨hler manifold X, a one deﬁnes twisted Gromov-Witten invariants of X to be intersection numbers in moduli spaces of stable maps f : Σ → X with the cap product of the virtual fundamental class and a chosen multiplicative invertible characteristic class of the virtual vector bundle H 0 (Σ, f ∗ E) H 1 (Σ, f ∗ E). Using the formalism of quantized quadratic Hamiltonians , we express the descendant potential for the twisted theory in terms of that for X. ...
Given the spatial relationships extracted as described above, our
goal is to integrate this information into an optimization framework
with a properly deﬁned cost function quantifying the quality of the
furniture arrangement. Given an arbitrary room layout populated by
furniture objects, the synthesized arrangement should be useful for
virtual environment modeling in games and movies, interior design
software, and other applications.
The search space of our problem is highly complex as objects are
interdependent in the optimization process.
Technology can be most broadly defined as the entities, both material and immaterial, created by the application of mental and physical effort in order to achieve some value. In this usage, technology refers to tools and machines that may be used to solve real-world problems. It is a far-reaching term that may include simple tools, such as a crowbar or wooden spoon, or more complex machines, such as a space station or particle accelerator. Tools and machines need not be material; virtual technology, such as computer software and business methods, fall under this definition of technology.
We prove a closed formula for integrals of the cotangent line classes against the top Chern class of the Hodge bundle on the moduli space of stable pointed curves. These integrals are computed via relations obtained from virtual localization in Gromov-Witten theory. An analysis of several natural matrices indexed by partitions is required.

SOME JOKER in the dear, dead days now virtually beyond recall won two-bit immortality by declaring that, "What this country needs is a good five-cent cigar." Which is, of course, Victorian malarkey. What this country really needs is a good five-cent nickel. Or perhaps a good cigar-shaped spaceship. There's a fortune waiting somewhere out in space for the man who can go out there and claim it. A fortune! And if you think I'm just talking through my hat, lend an ear … Joyce started the whole thing. Or maybe I did when for the umpteenth time I suggested she...
Virtual Learning Environments (VLEs), understood here as online systems supporting
interactions between and amongst learners and teachers as well as access to resources
and activities, have long been held to provide a range of benefits in further and higher
education. For 2008, UK Government policy is far all pupils to have access to an online
learning space, for many provided through a learning platform such as a VLE.
