In this paper, we develop tractable mathematical models and approximate solution algorithms for a class of integer optimization problems with probabilistic and deterministic constraints, with applications to the design of distributed sensor networks that h ...
The possibility of model reduction using global modes is readdressed, aiming at the controlling of a globally unstable separation bubble induced by a bump geometry. A combined oblique and orthogonal projection approach is proposed to design an estimator an ...
This paper studies non-cryptographic authenticated broad- cast in radio networks subject to malicious failures. We in- troduce two protocols that address this problem. The first, NeighborWatchRB, makes use of a novel strategy in which honest devices monito ...

This dissertation considers mechatronic systems driven by piezoelectric ultrasonic motors (PUM). The focus is set on optimal system design and sensorless position control. Mechatronic industry faces the challenge to deliver ever more efficient and reliable ...
An ephemeral network is usually defined by the very short-lived and heterogeneous nature of interactions among self-organizing wireless devices. The wide penetration in everyday gadgets of radio technologies operating in unlicensed frequency spectrum, such ...
Autonomous flight in confined or cluttered environments such as houses or urban canyons requires high manoeuvrability, fast mapping from sensors to actuators and very limited overall system weight. Although flying animals are well capable of coping with su ...
In this paper, we present a telerehabilitation system aiming to help the physiotherapists for the shoulder and elbow treatment. It is based on a two-arm haptic force feedback to avoid excessive efforts and discomfort with the spinal column. This system, re ...
Due to their very nature, wireless sensor networks are probably the category of wireless networks most vulnerable to “radio channel jamming”-based Denial-of-Service (DoS) attacks. An adversary can easily mask the events that the sensor network should detec ...
The development, deployment, and control of groups of robots is a tedious process even for experienced roboticists. Particularly in heterogeneous systems a high granularity of control and visibility is difficult to achieve. The lack of standardized interfa ...
Use of daylight offers great potential benefits in terms of energy savings, visual comfort and health, as long as it is properly controlled. This project is motivated by the necessity to describe façade systems and interior surfaces in order to quantify an ...
