Humans have an extraordinary flexibility in generating movements. With little attention most of us can perform complex tasks such as walking or riding a bicycle. The central nervous system integrates available sensory information and select the proper motor command for the muscles. The skeletal system enables the transfer of forces required for body movement while the muscles produce the forces to accelerate it. Stability is maintained through both passive (intrinsic muscle properties) and active (reflexes) contributions to the visco-elasticity of the joints. In this course we investigate how humans generate movements, stabilize posture, and integrate sensory feedback into control actions, while acknowledging the kinematics and the mechanical properties of the human motor system. This course addresses fundamental aspects and clinical applications. During the course the role of subsystems (e.g. muscles, sensory systems) and their interactions as well as uncertainty in sensory signals are discussed with a focus on reaching movements and posture maintenance. During the course it will be shown how this knowledge can help in understanding impaired motor function after neurological disorders, like Stroke and Parkinson s disease.

This first part of the course Introduction to Aerospace Engineering presents an overall picture of the aeronautics domain. This overview involves a number of different perspectives on the aerospace domain, and shows some basic principles of the most important concepts for flight. Then the basic aerodynamics are covered, followed by flight mechanics.

In the design of aircraft, failure of any of the primal load carrying structure has major and unacceptable consequences. A type of structural application is a box structure. There are box structures that are used in all kinds of structural applications (e.g.Wings in aircraft, structure of a satellite, blades of a wind turbine). In the project, groups of appoximately 8-10 students will act as a structural design team. In a first design loop, your assignment is to design, build and test a box structure, with given outer dimensions and a limited number of variables. The design should be such that it can sustain specified loads with minimal structural weight and structural components. In a second design loop, you will be given the opportunity to explore the properties and behavior of different material types and alternative structural elements. Using this knowledge, a theoretical redesign of the box structure can be made.
