This work presents results of the use of a wavelet filter for noise reduction and data compression of signals generated by artificial nose sensors. To verify the performance of the wavelet analysis in the treatment of odor patterns, we compare two widely used artificial nose classifiers, multi-layer perceptron neural network and time delay neural network in the analysis of signals generated by ...

A new block-based noise reduction system is proposed which focuses on the preservation of transient sounds like stops or speech onsets. The power level of consonants has been shown to be important for speech intelligibility. In single-channel noise reduction systems, however, these sounds are frequently severely attenuated. The main reasons for this are an insufficient temporal resolution of tr...

Previous research in the tradeoff between throughput and delay in wireless networks has focused on networks with fixed nodes or nodes with random mobility. In this paper, motivated to study fundamental limits of delay in a wireless network with maximal throughput, we examine delay scaling in networks in which the mobile nodes may control their own motion and schedule the pickup and delivery of ...

BACKGROUND Delay discounting is a reduction in the subjective value of a delayed outcome. Elevated delay discounting is a type of impulsivity that is associated with harmful behaviors, including substance abuse and financial mismanagement. METHODS Elevated delay discounting as related to addiction and financial mismanagement was reviewed from psychological, neurobiological, and behavioral eco...

this article proposes a direct method for solving three types of integral equations with time delay. by using operational matrix of integration, integral equations can be reduced to a linear lower triangular system which can be directly solved by forward substitution. numerical examples shows that the proposed scheme have a suitable degree of accuracy.

Abstract In this paper, we consider a diffusive predator–prey model with time delay and prey toxicity. The effect of on the stability positive equilibrium is studied by analyzing eigenvalue spectrum. Delay-induced Hopf bifurcation also investigated. By utilizing normal form method center manifold reduction for partial functional differential equations, formulas determining property are given.

Video data forms the major traffic in today’s internet. Quality Of internet video has a great impact on user engagement. Video encoding and streaming over wireless networks become a big concern. Real time video service requires low end-to-end delay, which mainly consists of video encoding delay, queuing delay, and transmission delay. The major concern is to reduce the queuing delay which has hi...
