Maximum length sequence and Bessel diffusers using active technologies
Active technologies can enable room acoustic diffusers to operate over a wider bandwidth than passive devices, by extending the bass response. Active impedance control can be used to generate surface impedance distributions which cause wavefront dispersion, as opposed to the more normal absorptive or pressure-cancelling target functions. This paper details the development of two new types of ac...
متن کاملAdaptive Equalization System for Wireless Communication Using White LED
White LEDs were invented the 1990’s. The white LED has lower power consumption, lower voltage requirements, longer lifetime, smaller size, faster response, and cooler operation. We have proposed an indoor visible light wireless communication system that utilizes multiple white LED lighting equipment. In this system, the equipment is used not only for illuminating rooms but also for an optical w...
متن کاملUse of maximum length sequence analysis in newborn hearing testing.
The use of maximum length sequence analysis (MLSA) with rapid click rates may be of clinical value in newborn hearing screening because a greater number of individual responses can be signal averaged without adding to test time. To examine the potential clinical value of MLSA in newborn screening, auditory brainstem responses (ABRs) from 50 premature newborns were studied. ABRs were acquired wi...
متن کاملMaximum Margin Active Learning for Sequence Labeling with Different Length
Sequence labeling problem is commonly encountered in many natural language and query processing tasks. SVM is a supervised learning algorithm that provides a flexible and effective way to solve this problem. However, a large amount of training examples is often required to train SVM, which can be costly for many applications that generate long and complex sequence data. This paper proposes an a...
متن کاملReciprocal maximum-length sequence pairs for acoustical dual source measurements.
In this paper we propose and demonstrate a method to obtain simultaneous dual source-receiver impulse responses in acoustical systems using binary maximum-length sequences (MLS). A binary MLS and its reversed-order sequence form a reciprocal MLS pair. Their correlation property includes a two-valued "pulse-like" autocorrelation function and a relatively smaller-valued cross-correlation function...
