16. Ommatidial adaptations for vision in nocturnal insects
Abstract : Nocturnal vision is a demanding task for insects with small eyes. As it gets dimmer the noise imposed by the stochastic nature of photon arrival makes vision unreliable. Despite this, there are quite a number of animal species that are active at night and apparently see well. READ MORE

17. Evolution of Vertebrate Eyes: a study on lens suspension and optical proterties
Abstract : Many fishes have well-developed visual systems with color vision capabilities. The crystalline lens is the major refractive element in a fish eye since the cornea is optically inactive underwater. A typical fish eye has a large pupil and a lens of short focal length, features that increase light gathering ability. READ MORE

18. An Embodied Account of Action Prediction
Abstract : Being able to generate predictions about what is going to happen next while observing other people’s actions plays a crucial role in our daily lives. Different theoretical explanations for the underlying processes of humans’ action prediction abilities have been suggested. READ MORE

19. Resonator sensor technique for medical use : an intraocular pressure measurement system
Abstract : In the work of this doctoral dissertation a new resonator sensor technique, first presented in 1989, has been further developed and evaluated with focus on technical characteristics and applications within the medical field. In a first part a catheter-type tactile sensor using the resonator sensor technique was evaluated in a silicone model and applied to human prostate in vitro. READ MORE

20. Intraocular Microdialysis
Abstract : The method of microdialysis has been adapted for ocular use. It is a technique for monitoring concentrations of different molecules in a tissue in vivo. It is based on the principle of diffusion through a semipermeable membrane. The membrane is mounted on a soft plastic shaft, connected to an inlet and an outlet tube. READ MORE
