Basicaly,a chatterbot is a computer program that when you provide it with some inputs in Natural Language (English, French ...) responds with something meaningful in that same language. Which means that the strength of a chatterbot could be directly measured by the quality of the output selected by the Bot in response to the user. By the previous description,we could deduce that a very basic chatterbot can be written in a few lines of code in a given specific programming language. Lets make our first chatterbot (notice that all the codes that will be used in this tutorial will be written in C++. Also, it is assumed that the reader is familiar wih the STL library)
With the Wireless module, OPNET can model both
terrestrial and satellite radio systems. In this tutorial,
you will use Modeler and Wireless modeling to create a
radio network you will also observe variations in the
quality of received signal that results from radio noise
at the receiving node in a dynamic network topology.
We show in the context of a new economic geography model that when
labor is heterogenous trade liberalization may lead to industrial agglomeration
and inter-regional trade. Labor heterogeneity gives local monopoly
power to firms but also introduces variations in the quality of the job match.
Matches are likely to be better when there are more firms and workers in
the local market, giving rise to an agglomeration force which can offset the
forces against, trade costs and the erosion of monopoly power. We derive
analytically a robust agglomeration equilibrium and illustrate its properties
with numerical simulations
The concept of smart cities emerged few years ago as a new vision for urban
development that aims to integrate multiple information and communication
technology (ICT) solutions in a secure fashion to manage a city’s assets. Modern ICT
infrastructure and e-services should fuel sustainable growth and quality of life,
enabled by a wise and participative management of natural resources to be ensured
by citizens and government. The need to build smart cities became a requirement that
relies on urban development that should take charge of the new infrastructures for
smart cities (broadband infrastructures, wireless sensor networks, Internet-based
networked applications, open data and open platforms) and provide various smart
services and enablers in various domains including healthcare, energy, education,
environmental management, transportation, mobility and public safety.
The surge of mobile data traffic forces network
operators to cope with capacity shortage. The deployment of
small cells in 5G networks is meant to reduce latency, backhaul
traffic and increase radio access capacity. In this context, mobile
edge computing technology will be used to manage dedicated
cache space in the radio access network. Thus, mobile network
operators will be able to provision OTT content providers with
new caching services to enhance the quality of experience of their
customers on the move.
Thisbookfocusesontheemergingresearchtopic‘green(energy-efficient)wirelessnetworks’
that has drawn huge attention recently from both academia and industry. This topic is highly
motivated due to important environmental, financial and quality-of-experience (QoE) consid-
erations.Duetosuchconcerns,varioussolutionshavebeenproposedtoenableefficientenergy
usage in wireless networks, and these approaches are referred to as green wireless communi-
cations and networking. The term ‘green’ emphasizes the environmental dimension of the
proposed solutions. Hence, it is not sufficient to present a cost-effective solution unless it is
eco-friendly.
Rapid growth of wireless communication services in recent decades has created
a huge demand of radio spectrum. Spectrum scarcity and utilization inefficiency
limit the development of wireless networks. Cognitive radio is a promising tech-
nology that allows secondary users to reuse the underutilized licensed spectrum of
primary users. The major challenge for spectrum sharing is to achieve high spectrum
efficiency while making non-intrusive access to the licensed bands. This requires in-
formation of availability and quality of channel resources at secondary transmitters,
however, is difficult to be obtained perfectly in practice.
