The STRL organises a series of seminars which are held most weeks of
the University academic semesters. These are given by members of the
laboratory as well as some external speakers.
The list of the forthcoming seminars is given below.

Performance Simulation of a System's Parallelisation
Date: Tuesday 5th March
Location: Bede Island, BI 1.11
Time: 13:00--14:00
Abstract
The performance of computer system's was already considered since
the beginning of computing. New methodologies to support performance
engineering were developed to face the problem of ever rising
performance issues within the systems. A fundamental problem in
performance engineering studies is the lack of accurate cost-benefit
analysis to allow a gain-oriented optimisation of the
systems. Therefore, the framework of dynamic performance stubs has
been introduced. It allows the performance simulation of possible
optimisations prior to a costly implementation. Thus, accurate
cost-benefit analysis can be carried out and lead to a more
gain-oriented performance optimisation of computer systems.
But today, the performance of computer systems is not increased by
using faster processors but by using several processors in
parallel. Therefore, the parallelisation of software becomes an
important and promising approach for the performance
optimization. But, sufficient cost-benefit-analysis for the
parallelisation of a system are still not available. Therefore, this
talk presents an extended methodology that applies dynamic
performance stubs to investigate possible parallelisations of a
system under test. It provides some basic information on
parallelisation and dynamic performance stubs as related work. This
is followed by the presentation of a new methodology that allows the
analysis and simulation of several parallelisation aspects. With
this an estimation whether the parallelisation of the system is a
promising approach for it's optimisation can be given. Finally, the
talk concludes with the presentation of a proof of concept and the
discussion of a first case study's results and their impact on the
further research work.

Towards a testing approach for RFID applications
Date: Tuesday 5th March
Location: Bede Island, BI 1.11
Time: 14:00--15:00
Abstract
Radio Frequency Identification(RFID) technology uses radio waves
to identify objects. The use of radio waves brings several
advantages to the automatic identification process, e.g. line of
sight is not needed anymore. The technology is gaining momentum and
strives to substitute the legacy bar code in the mid and long
run. However, small and mediums sized companies (SME) are still
struggling to adopt this new technology into their business
environment. One of the main reasons for delayed introduction is the
implementation costs which are significantly determined by the
related software.
Testing of software is a significant factor for the overall cost. To
reduce the cost and allow methodical testing of RFID applications
research in this domain is necessary. Additionally, many recent RFID
projects are still tested manually, which is a result of missing
literature, tools and methodologies. Therefore, this talk presents
an approach to specify RFID applications which can be used to
generate test code of testing RFID applications. It will introduce
the basics of RFID systems, the typical infrastructure and protocols
used today, as well as the related work. This is followed by the
novel approach towards specifying functional behavior of RFID
applications and a virtual RFID framework, which can be used to
execute the test cases.
