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 -
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 -
Low-Power Network Design: Work Hard, Play Hard
(2019)With the rapid expansion of the Internet of Things, an increasing number of applications relies on reliable, energy-efficient, and low-latency communication between small networked wireless devices. A large number of wireless communication protocols dealing with these challenges have been proposed in recent years. Their performance typically varies greatly with the application and environment they are used in. The EWSN Dependability ...Student Paper -
Preparation and characterization of mechanically alloyed, yttria containing steel powder for additive manufacturing of dispersion strengthened steels
(2019)Oxide-dispersion-strengthened (ODS) steel is a material that is being studied for its potential in high-temperature and high-irradiation applications, such as nuclear fusion reactors or IV generation fission reactors. Its properties derive from the presence of nano-dispersed oxide particles that act as a barrier against the movement of dislocations, hence reducing susceptibility to creep, and as sinks for irradiation-induced defects, thus ...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 -
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 -
Chance-Constrained Programming for Autonomous Vehicles in Uncertain Environments
(2018)Trajectory planning in uncertain environments arises in several autonomous system applications including robotics, air traffic and autonomous driving. An approach to handle uncertainties with sufficiently high safety guarantees is through chance-constrained optimization. In this work, we consider the problem of trajectory planning for an autonomous vehicle in an uncertain environment comprised of a number of obstacles. First, we explore ...Student Paper -
Unleashing the potential of Real-time Internet of Things
(2017)With the recent surge in the interest for the Internet of Things (IoT) and an increased deployment of cyber-physical systems (CPS) in commercial and indus- trial applications, distributed systems have gained a significance influence on modern civilization and are performing increasingly complex tasks. Building such platforms in a reliable manner is challenging, as they include concurrent tasks on the application and the communication ...Student Paper -
CLAIRE
(2017)CLAIRE is nothing yet. Notwithstanding it is so important that it received a name. The project is complex, the innovative concept carries different aspects so that it has been decided to use ’CLAIRE’ when one means to speak about the whole idea. In general CLAIRE is a knowledge management tool, naively CLAIRE is a program, a platform, a scientific map, etc. Until there, the reader may be careful to the abusive use of ”is”: it does not ...Student Paper -
The Comfort of Urban Cores: Understanding the Development, Qualities and Livability of Altstetten
(2017)Altstetten is one of the most rapily changing districts in the city of Zürich. Being crucial to Zürich’s future development, Altstetten’s spatial development as well as perception are of great interest. It offers a wide variety of characteristics, from a work-driven office district to a calm living area and busy industrial areas turning into lively mixed-used residential zones. During a short-term study during the summer of 2017 we ...Student Paper
