This investigation was conducted to assess the extent to which hearing aid-processed signals present an acoustic signal to the subject which has a frequency response equivalent to that which the hearing aid itself would have provided. The frequency response of a hearing aid receiver which was coupled directly to the ear canal ("aided" condition) was compared with the frequency response of the s...

This paper proposes a method for detecting feature interactions related to the functionality of a composite web service. There are several important ways in which functional features of Web Services can affect each other through interaction. A feature interaction is an undesirable side effect of the composition of services (also known as features in this context). There are various causes for i...

A multidomain spectral method for solving wave equations is presented. This method relies on the expansion of functions on basis of spherical harmonics (Y m l (θ, φ)) for the angular dependence and of Chebyshev polynomials Tn(x) for the radial part. The spherical domains consist of shells surrounding a nucleus and cover the space up to a finite radius R at which boundary conditions are imposed....

nano-sized titanium dioxide tio2 powder was prepared by new wet chemical route from its precursor titanium (iv) chloride (ticl4) as precursor with isopropoxy alcohol in presence of nitric acid under ambient condition. their morphologies, phase compositions and components of the tio2 nanoparticles were characterized by transmission electron microscopy (tem), field emission scanning electron micr...

A new 3D biped prototype with small DOF, SKIPPER, was developed. As an important component of a running controller for this robot, an aerial posture controller is presented. This is the extended version of planar running controller, which was previously developed for a passive one-legged hopping robot, and plays important roll for orbital stabilization at the lowest control layer. The controlle...

Many researchers studying legged locomotion have applied tools from reinforcement learning/optimal control to minimize characteristics of a walking gait, most notably the energy consumption. In this paper, we use similar tools to maximize the region of stability of the controller defined as the set of initial conditions from which the robot maintains its balance for at least 5 seconds. Experime...
