The Formalization and Representation of Expert Knowledge with Visual Analytics to Improve Product Quality in Serial Manufacturing Processes

December 09^th, 2021 | 11:00 pm | online

Advances in new technologies, such as the Internet of Things (IoT) and big data analytics are enabling a new generation of smart manufacturing processes. These technologies allow the efficient tracking of the quality of produced parts along every step in the manufacturing process.
Here, sophisticated measurement equipment forms interconnected IoT networks, where the “smartness” level depends to great extent on how organizations can leverage data-driven approaches to create value of resulting big datasets and to support human experts with their high-cognition analysis tasks. In this regard, Visual Analytics (VA) can help to integrate human experts into the visual exploration of IoT data by augmenting analytical reasoning capabilities together with model-supported and custom-designed visualization interfaces. Thus, in this thesis, we analyze the role of VA in serial manufacturing processes. Specifically, we aim to examine how such visualization approaches can be used to formalize and represent expert knowledge to make it readily accessible for the development of data-driven approaches, which show great potential in improving serial manufacturing processes. In doing so, we present results from four design study projects in collaboration with a German manufacturer of electric vehicles. Our results indicate that VA shows great potential in augmenting human analytical reasoning processes of knowledge-intensive tasks. Furthermore, we outline how features, models, and especially labels can be leveraged by organizations as explicit knowledge products to be shared among organizational members and leveraged to engage in sophisticated data-driven approaches.

Daniele Venturi introduce a new form of encryption that we name matchmaking encryption (ME). Using ME, sender S and receiver R (each with its own attributes) can both specify policies the other party must satisfy in order for the message to be revealed. The main security guarantee is that of privacy-preserving policy matching: During decryption nothing is leaked beyond the fact that a match occurred/did not occur. ME opens up new ways of secretly communicating, and enables several new applications where both participants can specify fine-grained access policies to encrypted data. For instance, in social matchmaking, S can encrypt a file containing his/her personal details and specify a policy so that the file can be decrypted only by his/her ideal partner. On the other end, a receiver R will be able to decrypt the file only if S corresponds to his/her ideal partner defined through a policy. On the theoretical side, we define security for ME, as well as provide generic frameworks for constructing ME from functional encryption. These constructions need to face the technical challenge of simultaneously checking the policies chosen by S and R, to avoid any leakage. On the practical side, we construct an efficient identity-based scheme for equality policies, with provable security in the random oracle model under the standard BDH assumption. We implement and evaluate our scheme and provide experimental evidence that our construction is practical. We also apply identity-based ME to a concrete use case, in particular for creating an anonymous bulletin board over a Tor network.

SAFEST project - a Hardware Security network

November 22^th, 2021 | 2:00 - 3:00 pm | IFEG042

In this talk, Prof. Pagliarini will introduce the SAFEST project and the opportunities for collaboration and staff exchanges between TU Graz and TalTech. SAFEST is a H2020 Twinning action, a type of project where partners are committed to cross-training each other on the complementary topics of (hardware) security and circuit design. In particular, Prof. Pagliarini's team provides expertise on the design of application specific integrated circuits (ASICs). The talk will also cover one successful collaboration between TalTech and TU Graz where a post-quantum crypto core named SABER was recently taped out in 65nm CMOS.

Computer science education in Bavaria: reacting to the challenges of digitization

When: October 19^th, 2021 from 17:00 - 18:00
Where: HS BE01, Steyrergasse 30, Ground Floor // Webex
Registration required!

The unstoppable digitization of all areas of life is changing our society sustainably and dramatically. School education must respond to this appropriately, i.e., on a broad front. This requires a carefully planned, long-term, evidence-based overall strategy designed for sustainability, which must touch (almost) all areas of school activity. In line with this universality of demands, an enormous diversity of terms used for informatics education is evident worldwide. We have identified over 40 relevant terms for this purpose. Equally diverse are the teaching contents offered in this area. The identification of competencies to be learned by students poses particular difficulties. There is very little preliminary research on this to date.
To master digital systems, our students need solid knowledge of their technical functioning and logical structure as well as competencies suitable for everyday use to apply digital tools effectively and efficiently. This foundation can only be learned in a dedicated subject of computer science. But all other school subjects must also respond to the challenges of digitization by adapting their learning objectives, learning methods and the media used accordingly. However, it is not easy to make such changes to an existing school system while it is still in operation. The greatest challenge here is the restructuring of pre- and in-service teacher education, both in computer science and in the didactics of all other subjects.
The German State of Bavaria already reacted to this challenge in 2000 with the introduction of a compulsory subject in computer science at its Gymnasien and Realschulen, which was significantly developed designed and supported by the author, i.a. in teacher education, curriculum work, and by writing textbooks. This was followed in 2019 by another major offensive by the state government, in which the existing compulsory subject of computer science was further expanded as well as newly introduced at main schools.
In this presentation, the basic concept of this subject will be presented, as well as some supporting activities such as teacher training. However, in the course of these activities, some persistent obstacles have also emerged that are very difficult to remove, Above all, the low enrollments in teacher training programs for computer science, as can be observed in almost all concerned countries. One possible reason for this could be found in the contradictory personal requirements of a teaching degree on the one hand and a computer science degree on the other.
