This paper presents a human dead-reckoning system for beaconless indoor positioning. The system is based on traditional dead-reckoning sensors like compass, gyro, and accelerometers. Due to the difficult kinematics of a human, there are no ready solutions for the odometry. This problem is solved by using a self-made stride length measurement unit and laser(More)
Space of two categories connects wievers emotionally with their own childhood. Each person entering the installation space creates a human-shaped view to the world of a little girl with their own shadows. The shadows act as gateways to another temporal state, which is illuminated inside shadows, normally dark and void. The installation deals with the(More)
Mars is currently the centre of interest for space exploration. Tremendous efforts are still in progress to find clues of existence of life on Mars. Rovers are major sources of information of Mars. This paper focuses on a robotic roving vehicle robot for scientific applications (ROSA) having its initiative of European Space Agency (ESA). ROSA being a(More)
This paper describes the assessment of the most relevant astronaut assistant activities on the surfaces of the Moon and Mars and, furthermore, the robotic technology development requirements to implement these activities with a centaur-like outdoor service robot, called the WorkPartner. The activity assessment is done by extracting five common mission(More)
This paper presents a human localization system for beaconless indoor positioning. The system is based on traditional dead-reckoning sensors including a compass, a gyro, and accelerometers. Due to the difficult kinematics of a human, there are no ready solutions for the dead reckoning. This problem is solved by using a self-made stride length measurement(More)
Cloud federation is receiving increasing attention due to the benefits of resilience and locality it brings to cloud providers and users. Our analysis of three diverse use cases shows that existing solutions are not addressing the federation needs of such use case applications. In this paper, we present an alternative approach to network federation,(More)
