Abstract:
The objective of this paper is to calculate filters with a minimum uncertainty, the product of filter length and bandwidth. The method is applicable to producing minimum uncertainty filters with time or frequency domain constraints on the filter. The calculus of variations is used to derive the conditions that minimize a filter’s uncertainty. The general solution is a linear combination of Hermite functions, where the Hermite functions are summed from low to high order until the filter’s constraints are met. Filters constrained to have zero amplitude at zero hertz have an uncertainty at least

Inferior vena cava filters are commonly encountered devices on diagnostic imaging that were highlighted in a 2010 Food and Drug Administration safety advisory regarding their complications from long-term implantation. The Predicting the Safety and Effectiveness of Inferior Vena Cava Filters (PRESERVE) trial is an ongoing after-market study investigating the safety and utility of commonly utilized filters in practice today. While most of these filters are safe, prompt recognition and management of any filter-associated complication is imperative to prevent or reduce the morbidity and mortality

AbstractA dualband rejection filter and a triband rejection filter are proposed in this letter, both of which are implemented by cascading spoof surface plasmon polaritons (SSPPs) of the same structure but with diverse rejection bands. Compared with traditional ones, the proposed filters provide more compact structures, wider rejection bands, and better independent tunability. In the proposed filters, the rejection bandwidth, the center frequency of the rejection band and the filter's cutoff frequency can be adjusted independently. And the different rejection bands in the same filter also can

This paper introduces an optical wave filter, which uses gratings at 45? or 135? inclined grating lines that avoid any resonance's. Therefore, many more options to form the filter shape exist. In general, the filter design can be traced to that of transversal filters (finite impulse response filter, FIR filter). Such an integrated optical wave filter is characterized by steep filter slopes and a narrow pass band (less then 01nm) combined with a high stop band attenuation (more than 40dB) and a linear phase response in the pass band.

Abstract:
Filters trade off accuracy for space and occasionally return false positive matches with a bounded error. Numerous systems use filters in fast memory to avoid performing expensive I/Os to slow storage. A fundamental limitation in traditional filters is that they do not change their representation upon seeing a false positive match. Therefore, the maximum false positive rate is only guaranteed for a single query, not for an arbitrary set of queries. We can improve the filter's performance on a stream of queries, especially on a skewed distribution, if we can adapt after encountering false posit

The ash deposits are generally found accumulated in a porous layer along the channel walls, or packed as end-plugs towards the back of the filter channels.

Composite filters, which are linear combinations of matched filters, allow arbitrary correlation peaks to be obtained for any objects but are usually associated with large sidelobes.

Abstract:
We present new extensions of steerable filters for image analysis. The architecture permits oriented filters to be applied efficiently over a continuous range of angles. The outputs of several basis filters give an analytic expression for the filter response as a function of angle. We extend our previous analysis to include three-dimensional image filters. The resulting local analysis of the orientation and the phase of volumetric data may be usefully applied to medical imagery and motion sequences. The approach permits considerable computational savings, because a small number of x–y–z separa

Abstract:
We built a collector to filter interplanetary dust particles (IDPs) larger than 5 µm from the clean air at the Amundsen Scott South Pole station. Our sampling strategy used long duration, continuous dry filtering of near-surface air in place of short duration, high-speed impact collection on flags flown in the stratosphere. We filtered ~107 m³ of clean Antarctic air through 20 cm diameter, 3 µm filters coupled to a suction blower of modest power consumption (5–6 kW). Our collector ran continuously for 2 years and yielded 41 filters for analyses. Based on stratospheric concentrations, we predic

Abstract:
This project investigated the velocity profile downstream from three commercially available dry gas filters and the effect of this profile on an ultrasonic meter installed in an AGA 9 default configuration. The inlet profile and condition of the filter element were varied to determine the sensitivity on the profile exiting the filter.

Abstract:
This workshop provides an overview of methodological and other search filters, in particular in the context of evidence synthesis. Participants will learn how to find, appraise and use these filters and gain an understanding of how and why filters are used by others. An official Instats certificate of completion is provided at the conclusion of the seminar.
