Keyword Spotting (KWS) is an essential component in a smart device for alerting the system when user prompts it with command. As these devices are typically constrained by computational and energy resources, KWS model should be designed small footprint. In our previous work, we developed lightweight dynamic filters which extract robust feature map within noisy environment. The learning variable...

A twin-cell electrochemical filter is demonstrated to reduce the CO concentration in reformate hydrogen. In this design, the potential and gas flow are switched between the two filter cells so that alternative CO adsorption and oxidation occur in each cell while providing a continuous flow of H2 to a fuel cell. The effects of filter switching time and applied potential on the CO concentration o...

In this paper we have designed and simulated a Band Pass Filter (BPF) at X-band frequency. This filter is designed for X-band weather radar application with 9500 MHz center frequency and bandwidth -3 dB is 120 MHz. The filter design was performed using a hairpin microstrip combined with an open stub and defected ground structure (DGS). The substrate used is Rogers RT5880 with a dielectric const...

This paper presents a fault detection and isolation (FDI) filter design to linearized longitudinal dynamics of a Boeing 747 series 100/200. The FDI filter design based on fundamental problem of residual generation (FPRG). In our case the fault detection filter is sensitive to elevator and stabilizer fault. The three type of actuator failures considered in this paper are lock failure, loss in ef...

This paper concerns the problem of tracking acoustic sources in reverberant environments by using a particle filter. The localization problem is transformed into the retrieval of the unobservable state of a dynamical model through noisy measures. Though effective, two problems are related to particle filter: the degeneracy phenomenon (all particles but one are not significative) and the loss of...

in this article, the effect of cells' radius on the behavior of wavelength switching optical filter andthe effect of the radius of the optical filters' key characteristics such as wavelength resonance onan optical filter based on photonic crystals, have been investigated. currently, the most commonapplied mechanism for designing optical filter based on photonic crystals is using twome...

A tunable eye-opening lattice filter for dispersion compensation is demonstrated on an ultra low-loss waveguide platform based on a compact high-aspect ratio Si3N4 core. A programmable 10th order lattice filter is demonstrated by cascading a total of 21 Mach-Zehnder interferometers with programmable delay lines of lengths designed at the baseband data rate. The filter has ...

Filter cache has been proposed as an energy saving architectural feature [9]. A filter cache is placed between the CPU and the instruction cache (I-cache) to provide the instruction stream. Energy savings result from accesses to a small cache. There is however loss of performance when instructions are not found in the filter cache. The majority of the energy savings from the filter cache in hig...

The ability of using aluminum filings which is locally solid waste was tested as a mono media in gravity rapid filter. present study conducted to evaluate the effect variation influent water turbidity (10, 20and 30 NTU); flow rate(30, 40, and 60 l/hr) bed height (30and60)cm on performance filter for 5 hours run time compare it with conventional sand results indicated that showed better than rem...
