The number of GPS-enabled devices are growing rapidly. A large segment of the growth is coupled to the growth of smartphones. Some location-based applications are relatively simple, requiring only a rough position estimate. Other applications provide services where the usefulness of the application is directly connected to the accuracy of GPS positioning. Lifelogging, fitness, and navigation ar...

The training of precise speech recognition models depends on accurate segmentation of the phonemes in a training corpus. Segmentation is typically performed using HMMs, but recent speech recognition work suggests that the transient acoustic features characteristic of manner-class phoneme boundaries (landmarks) may be more precisely localized using acoustic classifiers specifically designed for ...

In [?] Lin, Wang and Zhou propose the iterative Toeplitz filters algorithm as an alternative iterative algorithm for EMD. In this alternative algorithm, the average of the upper and lower envelopes is replaced by certain “moving average” obtained through a low-pass filter. Performing the tradition sifting algorithm with such moving averages is equivlalent to iterating certain convolution filter...

For the stationary invertible moving average process of order one with unknown innovation distribution F , we construct root-n consistent plug-in estimators of conditional expectations E(h(Xn+1)|X1, . . . , Xn). More specifically, we give weak conditions under which such estimators admit Bahadur type representations, assuming some smoothness of h or of F . For fixed h it suffices that h is loca...

The Bidirectional Texture Function (BTF) is the recent most advanced representation of visual properties of surface materials. It specifies their appearance due to varying spatial, illumination, and viewing conditions. Corresponding enormous BTF measurements require a mathematical representation allowing extreme compression but simultaneously preserving its high visual fidelity. We present a no...

this analysis was conducted on 31 synoptic stations in iran. initially, the mann-kendall test was administered in order to analyse the trend of alterations of these two components over time and the results suggest that 16% of the stations show significant relationship with annual precipitation (positive and negative). more stations showed significant relationships between sunspots and minimum a...

This paper provides a voltage mode (VM) multi input single output (MISO) universal filter with the help of voltage differencing inverting buffer amplifier (VDIBA). All the filter functions i.e., Low pass, band pass, band reject, high pass, and all pass filter functions can be realized without modifying the circuit configuration. The pole frequency can be independently tunable by its transconduc...

Abstract: The present work deals with voltage differencing current conveyor and its application in analog circuit design. There have been several major developments in the area of analog circuits which have taken place during the past four decades. There is a bulk of material available about the various active blocks developed past Current Conveyors.Among various modern active building blocks, ...
