These codes require an ASCII input file called input.dat of the following form:
Lower Limit on x Upper Limit on x Final Time
Pressure for x<0 when t=0 Density for x<0 when t=0 Speed for x<0 when t=0
Pressure for x>0 when t=0 Density for x>0 when t=0 Speed for x>0 when t=0
These codes produce 8 ASCII output files:
density.out. Density vs. x
entropy.out. Entropy vs. x
mach.out. Mach number vs. x
Massflux.out. Mass flux vs. x
pressure.out. Pressure vs. x
sound.out. Speed-of-sound vs. x
velocity.out. Velocity vs. x
waves.out. A description of the solution in terms of the three waves defined in the book (+,-,0).

Mobile wireless communications are in constant evolution due to the continu-
ously increasing requirements and expectations of both users and operators.
Mass multimedia* services have been for a long time expected to generate a large
amount of data traffic in future wireless networks [1]. Mass multimedia services
are, by definition, purposed for many people. In general, it can be distinguished
between the distribution of any popular content over a wide area and the distribu-
tion of location-dependent information in highly populated areas. Representative
examples include the delivery of live video streaming content (like sports compe-
titions, concerts, or news) and file download (multimedia clips, digital newspa-
pers, or software updates).

Thanks to the advances in micromachining fabrication technologies and significant
cost reduction due to Mass production, miniature sensors of angular rate, or
gyroscopes, found their way into the everyday life of every user of modern gadgets,
such as smart phones, tablets or even wristwatches. Often without realising, many
of us are carrying in our pockets fully equipped with all necessary sensors complete
inertial navigation systems that not so long ago were available only for advanced
vehicles in sea, land, air or space. Accelerometers and gyroscopes are found in
specifications of any gadget supposed to react to user movements. And one of the
most commonly used type of gyroscopes used to developed these systems is
Coriolis vibratory gyroscope (CVG).

Nowadays sensors are part of everyday life in a wide variety of fields: scientific
applications, medical instrumentation, industrial field, ...and, last but not least,
popular Mass production and low-cost goods, like smartphones and other mobile
devices. Markets and business behind the field of sensors are quite impressive.
A common trend for consumer applications is miniaturization which requires, on
one side, a lot of research, development efforts, and resources but, on the other
hand, allows costs and final application size reduction. In this scenario scientific
community and industries are very active to drive innovation.

In modern societies, the production and trade of goods all around the world is
constantly increasing. The latest technological achievements allow the
Mass-production of millions of items of every kind, which are being exchanged all
around the globe with unprecedented rapidity. At the same time, the problem of
identifying, classifying and tracking such a growing multitude of objects is con-
sequently arising.

Sensors are points ofcontact betweenthe material world ofatoms, Mass, andenergy
and the seemingly immaterial world of information, computation, and cognition.
Linking these two domains more tightly yields all sorts of practical benefits, such as
improvedinputdevicesforcomputers,moreeffectivemedicaldevices(implantedor
worn), more precise agricultural operations, better monitored buildings or bridges,
more secure payment systems, and more reliable sensor–actuator control systems.
There are many settings in which tighter coupling between digital and physical
planes can enhance safety, security, performance, and reliability.

Modern information technologies and the advent of machines powered by artificial
intelligence (AI) have already strongly influenced the world of work in the 21st century.
Computers, algorithms and software simplify everyday tasks, and it is impossible
to imagine how most of our life could be managed without them. However, is it
also impossible to imagine how most process steps could be managed without
human force? The information economy characterised by exponential growth
replaces the Mass production industry based on economy of scales

In this book for the optimisation of assembly conveyor lines we are dealing with series part production
featured by a medium complexity degree and a medium number of individual components and assembly
technique alternatives. Modern production techniques for medium to large series products or Mass
production usually involve assembly conveyor lines. They still use hand labour more or less automated.
The aim is to have monotonous and similar in type operations or such causing fatigue, stress and
production traumas, gradually replaced by automated assembly cycles, means and techniques. This
usually widely involves industrial robots and handlers. Higher productivity, lower cost and higher quality
of assembled products are usually required.

This paper presents a new type of electromagnetic damper with rotating inertial Mass that has been devel
oped to control the vibrations of structures subjected to earthquakes. The electromagnetic inertial Mass
damper (EIMD) consists of a ball screw that converts axial oscillation of the rod end into rotational motion
of the internal flflywheel and an electric generator that is turned by the rotation of the inner rod. The EIMD is
able to generate a large inertial force created by the rotating flflywheel and a variable damping force devel
oped by the electric generator. Device performance tests of reduced-scale and full-scale EIMDs were under
taken to verify the basic characteristics of the damper and the validity of the derived theoretical formulae.
Shaking table tests of a three-story structure with EIMDs and earthquake response analyses of a building
with EIMDs were conducted to demonstrate the seismic response control performance of the EIMD. The
EIMD is able to reduce story drifts as well as accelerations and surpasses conventional types of dampers
in reducing acceleration responses.
