Infrastructure Used / Managed by the group:
AIT Smart Room:
A smart room infrastructure comprising cameras,
microphone, microphone-arrays, controlling workstations,
along with a companion middleware infrastructure enabling
continuous monitoring of the room as well as processing of
the sensor data. The room is under construction. The floor
plan and some pictures from this smart room follow.
The goal of this laboratory is to promote understanding,
education and research in the areas of Autonomic and
Intelligent Systems which combine: self-management
regardless of device (PC, PDA, distributed system),
multimedia and multimodal human-machine interaction, context
aware middleware, novel applications, and intelligent, self-
managed networks. The laboratory aims to extend research
performed in other Autonomic Systems (like the Grid) and
take steps towards what the European Commission calls
"Ambient intelligence" as an extension and improvement of
"Ubiquitous Computing". This technological direction puts
humans at the centre of a self-managed, multimedia and
multimodal computing infrastructure that aims at satisfying
human needs for work, pleasure and improved quality of
living, without requiring special training or knowledge.
The main sensor equipment of this room are:
• NIST Mark III: 64 channel microphone array
It’s a linear microphone array consisting of
64 microphones, with 2cm spacing between them. It is used
for AUDIO SOURCE LOCALISATION(ASR) and BLIND SOURCE
SEPARATION(BSS)
- One PTZ (pan, tilt, zoom) camera
- Guided by the microphone array to focus on the speaker
- Targeted Audio Device
- Used for transmitting personal messages, directly to
someone in the room.
- Only the recipient is able to hear the message
transmitted from the Targeted Audio Device
- It is created with the collaboration of
Daimler-Crysler
Grid Programing testbed:
This is a small laboratory comprising SUN Solaris and Linux machines and
allowing students and researchers to experiment with state of the art Grid
middleware (i.e. Globus Toolkit 4.0.1). Linux and Solaris computers are
virtually interconnected with the Globus v4.0 grid middleware as a first step in
the implementation of a small scale grid infrastructure. Students and
researchers at AIT have also the opportunity to incorporate new technologies for
scheduling, resource discovery and allocation etc. CPU load traces and memory
traces from different computers Operating Systems (Windows, Solaris and Linux)
are combined with network activity traces in order to research the optimal
prediction of work loads and allocation of resources in high performance
applications on Grids. Generally students come in touch with a different
environment and they are able to deploy applications that can be distributed and
executed in parallel without having to take care of the infrastructure
underneath.
AIT Software Laboratory (Extensively used by the Autonomic Group) :
SSoftware Lab (common) This is a state-of-the-art, powerful computational,
network and laboratory infrastructure that has been set up to serve requirements
of all AIT professors, researchers and students. Indicatively, the computational
power of the SUN cluster consists of 4 SUN Twin-Processor servers (upgradeable
up to 8CPU's per server), 9 SUN Blades and 25 SUN Ray terminals. The network
supporting the SUN cluster is 100Mb full duplex forming a powerful distributed
computational system. The software laboratory caters both for the research and
the educational requirements. Half of the work- stations are organized in the
form of a classroom allowing the professor to project and demonstrate material
from his work-station in real-time, running programs and simulations that the
students can simultaneously access, execute and compare on the individual
work-stations. A variety of applications and educational programs, as well as
software development tools, simulation tools and telecommunication system design
tools are available. Indicatively, we list some of the available software
packages:
- Matlab / Simulink: Software package for the
development, design, and simulation of Digital Signal
Processing and Communication Systems (12 licenses)
- OPNETQ Software package for the simulation of data
networks(16 licenses)
- NS: Open Software for data network simulation - a
standard academic tool
- Rational software: Analysis and design of software
systems incorporating the latest technologies and
methodologies (e.g. object oriented programming).
- Oracle RDBMS: The full edition of the popular RDBMS
software (version 9) (10 licenses)
- Complete software development environment for Java,
J2EE (e.g. SUN NetBeans, Eclipse), C, C++, versioning /
team development
- Open source web servers and application servers
(e.g., JBoss, Apache, Tomcat).
