Local Linear Predictive Coding for High Resolution Time-frequency Analysis

F. Ishiyama

Proc. of 2017 IEEE International Symposium on Signal Processing and Information Technology (ISSPIT 2017), pp. 1–6, Bilbao, Spain, December 2017.

We are developing a method of time-frequency analysis on the basis of linear predictive coding (LPC). In contrast to standard LPC, which assumes an infinite number of samples, our method obtains instantaneous frequencies, instantaneous amplitude vary rates, and instantaneous amplitudes from a small number of samples. The time width for single local analysis can be much narrower than the period of oscillation of a given time series, enabling high resolution time-frequency analysis. We outline our method and use it to analyze electro-magnetic noise in comparison with short time Fourier transform to show its resolution.

Electrical and Kinesthetic Stimulation for Virtual Walking Sensation

IEEE Haptics Symposium 2018, San Francisco, USA, March 2018.

The effect of electrical stimulation applied to the lower limb tendons on the sensation of virtual walking was investigated. The virtual walking, here, is a passive experience in which the user sees and acts virtually as some other person did to learn through his/her experience. A display device was developed to provide electrical stimulation to sensory nerves in the Achilles tendon and the tibialis anterior tendon. A kinesthetic stimulus and visual stimulus were simultaneously provided to a seated participant. We measured the sensations of walking and translational motion regarding three factors of electrical, kinesthetic and visual stimuli. The result obtained from eleven participants revealed that the three factors were significant in enhancing the sensation of virtual walking. The electrical stimulation for proprioception seemed effective to compensate the characteristics of passive kinesthetic playback of experiences.

Interactive Proofs with Polynomial-time Quantum Prover for Computing the Order of Solvable Groups

F. Le Gall, T. Morimae, H. Nishimura, and Y. Takeuchi

arXiv: 1805.03385 [quant-ph], May 2018.

In this paper we consider what can be computed by a user interacting with a potentially malicious server, when the server performs polynomial-time quantum computation but the user can only perform polynomial-time classical (i.e., non-quantum) computation. Understanding the computational power of this model, which corresponds to polynomial-time quantum computation that can be efficiently verified classically, is a well-known open problem in quantum computing. Our result shows that computing the order of a solvable group, which is one of the most general problems for which quantum computing exhibits an exponential speed-up with respect to classical computing, can be realized in this model.
