Abel, Felix (author), Ferent, Cristian (author), Sundaramoorthy, P.P. (author), Rajan, R.T. (author)This decade has seen growing interest in Mars exploration. Advances in distributed systems, miniaturization and commoditization of space electronics and innovations in communications permit us to rethink the current paradigm of relying on a few heavy, slow and expensive high-tech rovers for Mars surface exploration. In this work, we address the...conference paper 2022

Anjali Reji Isac, Anjali (author)Overhead power lines play a key role in the transmission and distribution of electrical power. Traditionally, the operating limits of these overhead lines are fixed and determined through static line rating. These limits are designed under conservative conditions such as high loads and extreme weather scenarios. However, the global energy demand...master thesis 2021

van 't Hof, Jos (author)Low downlink data rates limit the scientific and commercial return from small satellites. Now with constellations of small satellites becoming popular, the amount of data generated in low Earth orbit will be greater than ever. A novel data downlink architecture for small satellites is investigated that uses non-geostationary orbit (mega-...master thesis 2021

Rademakers, Roeland (author)The relay in short track skating is a team effort with the possibility to regain strength during the race by performing an exchange with a team member. Couples can gain time and conserve kinetic energy with a well performed exchange. However, the exchange is a difficult operation. With few studies done to find out what makes a good relay...master thesis 2020

Azizi, Sadegh (author), Sun, Mingyu (author), Liu, Gaoyuan (author), Popov, M. (author), Terzija, Vladimir (author)Short-circuit faults close to either end of a transmission line, are normally cleared instantaneously by the distance relay at that end and after hundreds of milliseconds, i.e., in Zone 2 operating time, by the relay at the opposite end of the line. This sequential tripping can be accelerated on condition that a reliable communication link is...journal article 2019

Azizi, Sadegh (author), Sun, Mingyu (author), Terzija, Vladimir (author), Popov, M. (author)Short-circuit faults occurring close to either end of a transmission line are normally cleared with some time delay by the distance relay at the opposite end of that line. The pilot relaying schemes require communication media in order to reduce this time delay. This paper presents a noncommunication method that provides high-speed distance...conference paper 2019

Brilstra, Stefan (author)In the high-tech semiconductor industry floating air conveyors are used to transport and position silicon substrates. An interesting point for improvement is to limit the loss of pressurized air as conveyors are only effective at the position of the substrate.<br/>The goal of this research is to develop a local pneumatic valve, that is...master thesis 2017

Arroyo Valles, M.D.R. (author), Simonetto, A. (author), Leus, G.J.T. (author)In wireless sensor networks, where energy is scarce, it is inefficient to have all nodes active because they consume a non-negligible amount of battery. In this paper we consider the problem of jointly selecting sensors, relays and links in a wireless sensor network where the active sensors need to communicate their measurements to one or...journal article 2017
