3D-Printed Inflatable Actuators
(2019)Designing soft inflatable actuators is not a trivial task due to the coupling between their function and their mechanical design. Hence, in order to realize a functional design, numerous design parameters and their interdependencies have to be studied. As a result, the design process is often both tedious and ambiguous as there is no well-defined approach to guide it. In this semester project, 3D-printed inflatable actuators were designed, ...Student Paper -
Optimizing Deep-stall Landing Maneuvers on Small Fixed-wing UAVs
(2019)The increasing importance of UAVs in today’s world is undisputed. However, fixedwing UAVs are often marginalized. This marginalization is often caused by the difficulties landing them. Landing in deep-stall is an approach to deal with this issue. It allows landing at steep flightpath angles and at low horizontal speed, thanks to massively increased drag and reduced lift. This is possible without needing any additional tools like ...Student Paper -
Multi-sensor wireless sensor network nodes for alpine environment monitoring
(2019)The Pizol Glacier is the first glacier in Switzerland to be declared dead in 2019 and it will not be the last if global warming continues to this extent. Because glaciers and permafrost are melting, our mountains are becoming more and more unstable. In the coming years it is expected that dangerous rockfalls will increase in size and quantity and that they will also occur in previously safe areas. At the same time, leisure activities ...Student Paper -
AI in Military Enabling Applications
(2019)CSS Analyses in Security PolicyThe public debate over military use of artificial intelligence (AI) mainly revolves around autonomous weapons systems. Looking beyond the specific ethical and political considerations associated with that issue, there are important questions relating to the organizational, technical, and functional integration of AI-enabled systems that determine the balance between potential benefits and risks.Other Publication -
Russia and China: The Potential of Their Partnership
(2019)CSS Analyses in Security PolicyRussia and China are celebrating their “strategic partnership”, and have been vastly expanding their cooperation since 2014. Their close alliance is based on economic and geopolitical considerations. While it is mutually beneficial, it also has its limitations. However, in the midterm, both China and Russia appear to be willing to overlook potential fields of tension, for instance in Central Asia.Other Publication -
Truth be told: Benchmarking BLE and IEEE 802.15.4
(2019)A large body of recent flooding-based communication protocol proposals for wire- less sensor networks exploit concurrent transmissions (CT). Many existing pro- tocols are designed to run on the IEEE 802.15.4 physical layer. Thus, there is extensive research on the conditions required for successfully receiving CT over IEEE 802.15.4. While IEEE 802.15.4 is popular in the research community, Blue- tooth Low Energy (BLE) has experienced ...Student Paper -
Equivalence of the catalytic entropy conjecture and the transitivity conjecture is plausible
(2019)In essence, the catalytic entropy conjecture states that for a given initial state and a target state with higher entropy there exists a unitary operator acting on the tensor product of the initial state and a state of an auxiliary system such that the marginal states after the action of the unitary are precisely the target state and the same auxiliary state respectively. Since the state of the auxiliary system remains unchanged, we refer ...Student Paper -
Is low-power wireless networking a reproducible science?
(2019)Recently, a noticeable number of attempts to reproduce experimental results across many different scientific fields were unsuccessful. In the field of low- power wireless networking, the dynamic behavior of the environment causes an inherited variability in the performance of wireless networking protocols, placing under consideration their reproducibility. In this semester project, a methodology for evaluating the performance of low- power ...Student Paper -
Low-power network design: work hard, play hard
(2019)Competing in a well-known competition in a field that you have no experience in can be hard for sure. In this semester thesis, we describe how we managed to design a low-power wireless protocol for a sensor network in less than 3 months of part-time work. Baloo is a novel protocol design framework, which offers an abstraction layer from the underlying hardware and enables fast protocol prototyping. Using Baloo, our goal was to create a ...Student Paper -
