Informaticology: combining Computer Science, Data Science, and Fiction Science
Motivated by an intention to remedy current complications with Dutch
terminology concerning informatics, the term informaticology is positioned to
denote an academic counterpart of informatics where informatics is conceived of
as a container for a coherent family of practical disciplines ranging from
computer engineering and software engineering to network technology, data
center management, information technology, and information management in a
broad sense.
Informaticology escapes from the limitations of instrumental objectives and
the perspective of usage that both restrict the scope of informatics. That is
achieved by including fiction science in informaticology and by ranking fiction
science on equal terms with computer science and data science, and framing (the
study of) game design, evelopment, assessment and distribution, ranging from
serious gaming to entertainment gaming, as a chapter of fiction science. A
suggestion for the scope of fiction science is specified in some detail.
In order to illustrate the coherence of informaticology thus conceived, a
potential application of fiction to the ontology of instruction sequences and
to software quality assessment is sketched, thereby highlighting a possible
role of fiction (science) within informaticology but outside gaming
On properties of modeling control software for embedded control applications with CSP/CT framework
This PROGRESS project (TES.5224) traces a design framework for implementing embedded real-time software for control applications by exploiting its natural concurrency. The paper illustrates the stage of yielded automation in the process of structuring complex control software architectures, modeling controlled mechatronic systems and designing corresponding control laws, simulating them, generating control code out of simulated control strategy and implementing the software system on a (embedded) computer. The gap between the development of control strategies and the procedures of implementing them on chosen hardware targets is going to be overcome
Prototype of Fault Adaptive Embedded Software for Large-Scale Real-Time Systems
This paper describes a comprehensive prototype of large-scale fault adaptive
embedded software developed for the proposed Fermilab BTeV high energy physics
experiment. Lightweight self-optimizing agents embedded within Level 1 of the
prototype are responsible for proactive and reactive monitoring and mitigation
based on specified layers of competence. The agents are self-protecting,
detecting cascading failures using a distributed approach. Adaptive,
reconfigurable, and mobile objects for reliablility are designed to be
self-configuring to adapt automatically to dynamically changing environments.
These objects provide a self-healing layer with the ability to discover,
diagnose, and react to discontinuities in real-time processing. A generic
modeling environment was developed to facilitate design and implementation of
hardware resource specifications, application data flow, and failure mitigation
strategies. Level 1 of the planned BTeV trigger system alone will consist of
2500 DSPs, so the number of components and intractable fault scenarios involved
make it impossible to design an `expert system' that applies traditional
centralized mitigative strategies based on rules capturing every possible
system state. Instead, a distributed reactive approach is implemented using the
tools and methodologies developed by the Real-Time Embedded Systems group.Comment: 2nd Workshop on Engineering of Autonomic Systems (EASe), in the 12th

A Hardware Time Manager Implementation for the Xenomai Real-Time Kernel of Embedded Linux
Nowadays, the use of embedded operating systems in different embedded
projects is subject to a tremendous growth. Embedded Linux is becoming one of
those most popular EOSs due to its modularity, efficiency, reliability, and
cost. One way to make it hard real-time is to include a real-time kernel like
Xenomai. One of the key characteristics of a Real-Time Operating System (RTOS)
is its ability to meet execution time deadlines deterministically. So, the more
precise and flexible the time management can be, the better it can handle
efficiently the determinism for different embedded applications. RTOS time
precision is characterized by a specific periodic interrupt service controlled
by a software time manager. The smaller the period of the interrupt, the better
the precision of the RTOS, the more it overloads the CPU, and though reduces
the overall efficiency of the RTOS. In this paper, we propose to drastically
reduce these overheads by migrating the time management service of Xenomai into
a configurable hardware component to relieve the CPU. The hardware component is
implemented in a Field Programmable Gate Array coupled to the CPU. This work
was achieved in a Master degree project where students could apprehend many
fields of embedded systems: RTOS programming, hardware design, performance
evaluation, etc.Comment: Embed With Linux (EWiLi) workshop, Lorient : France (2012
Automated user documentation generation based on the Eclipse application model
An application's user documentation, also referred to as the user manual, is
one of the core elements required in application distribution. While there
exist many tools to aid an application's developer in creating and maintaining
documentation on and for the code itself, there are no tools that complement
code development with user documentation for modern graphical applications.
Approaches like literate programming are not applicable to this scenario, as
not a library, but a full application is to be documented to an end-user.
Documentation generation on applications up to now was only partially feasible
due to the gap between the code and its semantics. The new generation of
Eclipse rich client platform developed applications is based on an application
model, closing a broad semantic gap between code and visible interface. We use
this application model to provide a semantic description for the contained
elements. Combined with the internal relationships of the application model,
these semantic descriptions are aggregated to well-structured user
documentations that comply to the ISO/IEC 26514. This paper delivers a report
on the Ecrit research project, where the potentials and limitations of user
documentation generation based on the Eclipse application model were
investigated.Comment: 9 pages, 9 figure
What is the method in applying formal methods to PLC applications?
The question we investigate is how to obtain PLC applications with confidence in their proper functioning. Especially, we are interested in the contribution that formal methods can provide for their development. Our maxim is that the place of a particular formal method in the total picture of system development should be made very clear. Developers and customers ought to understand very well what they can rely on or not, and we see our task in trying to make this explicit. Therefore, for us the answer to the question above leads to the following questions: Which parts of the system can be treated formally? What formal methods and tools can be applied? What does their successful application tell (or does not) about the proper functioning of the whole system
A Software Radio Challenge Accelerating Education and Innovation in Wireless Communications
This Innovative Practice Full Paper presents our methodology and tools for
introducing competition in the electrical engineering curriculum to accelerate
education and innovation in wireless communications. Software radio or
software-defined radio (SDR) enables wireless technology, systems and standards
education where the student acts as the radio developer or engineer. This is
still a huge endeavor because of the complexity of current wireless systems and
the diverse student backgrounds. We suggest creating a competition among
student teams to potentiate creativity while leveraging the SDR development
methodology and open-source tools to facilitate cooperation. The proposed
student challenge follows the European UEFA Champions League format, which
includes a qualification phase followed by the elimination round or playoffs.
The students are tasked to build an SDR transmitter and receiver following the
guidelines of the long-term evolution standard. The metric is system
performance. After completing this course, the students will be able to (1)
analyze alternative radio design options and argue about their benefits and
drawbacks and (2) contribute to the evolution of wireless standards. We discuss
our experiences and lessons learned with particular focus on the suitability of
the proposed teaching and evaluation methodology and conclude that competition
in the electrical engineering classroom can spur innovation.Comment: Frontiers in Education 2018 (FIE 2018
