This document specifies a collection of compiler directives, library routines, and
environment variables that can be used to specify shared-memory parallelism in C, C++
and Fortran programs. This functionality collectively defines the specification of the
OpenMP Application Program Interface (OpenMP API). This specification provides a
model for parallel programming that is portable across shared memory architectures
from different vendors. Compilers from numerous vendors support the OpenMP API.
More information about OpenMP can be found at the following web site:
Quake 3 s MD3 Viewer (july 13, 2007), loads and displays a player and a weapon.
Supports lighting, texture mapping and animation.
Includes a sample player model with weapon. See README for how to use it.
Note (1): it uses the POSIX opendir/readdir functions, which are not implemented in all compilers under Windows (MinGW supports them).
Note (2): This demo works on little endian architectures only.
Libraries: OpenGL, GLU, GLUT, boost, libjpeg.

Introduction
jSMPP is a java implementation (SMPP API) of the SMPP protocol (currently supports SMPP v3.4). It provides interfaces to communicate with a Message Center or an ESME (External Short Message Entity) and is able to handle traffic of 3000-5000 messages per second.
jSMPP is not a high-level library. People looking for a quick way to get started with SMPP may be better of using an abstraction layer such as the Apache Camel SMPP component: http://camel.apache.org/smpp.html

The contemporary view of the Smart City is very much static and infrastructure-
centric, focusing on installation and subsequent management of Edge devices and
analytics of data provided by these devices. While this still allows a more efficient
management of the city’s infrastructure, optimizations and savings in different do-
mains, the existing architectures are currently designed as single-purpose, vertically
siloed solutions. This hinders active involvement of a variety of stakeholders (e.g.,
citizens and businesses) who naturally form part of the city’s ecosystem and have an
inherent interest in jointly coordinating and influencing city-level activities.
Mobile communication devices like smart phones or tablet PCs enable us to
consume information at every location and at every time. The rapid development
of new applications and new services and the demand to access data in real time
create an increasing throughput demand. The data have to be transmitted reliably
to ensure the desired quality of service. Furthermore, an improved utilization of
the bandwidth is desired to reduce the cost of transmission.
In the nineteenth century, scientists, mathematician, engineers and innovators started
investigating electromagnetism. The theory that underpins wireless communications was
formed by Maxwell. Early demonstrations took place by Hertz, Tesla and others. Marconi
demonstrated the first wireless transmission. Since then, the range of applications has
expanded at an immense rate, together with the underpinning technology. The rate of
development has been incredible and today the level of technical and commercial maturity
is very high. This success would not have been possible without understanding radio-
wave propagation. This knowledge enables us to design successful systems and networks,
together with waveforms, antennal and transceiver architectures. The radio channel is the
cornerstone to the operation of any wireless system.
