Frequency-response masking (FRM) technique produces a filter network which comprises several sub-filters with very sparse coefficient values. If the sub-filters are optimized seperately, the overall filter network will be suboptimal. In this paper, an unconstrained weighted least squares algorithm for simultaneously optimizing the sub-filters generated by the frequency-response masking techniqu...

Frequency response masking (FRM) technique along with the Canonic Signed Digit (CSD) representation is a good alternative for the design of a computationally efficient, sharp transition width, high speed finite impulse response (FIR) filter. This paper proposes two novel approaches for the joint optimization of an FRM FIR digital filter in the CSD space. The first approach uses the recently eme...

During an USEPA study in the Phoenix area from 1995-1998, measurements from a federal reference method (FRM) monitor, calibrated in accordance with National Ambient Air Quality Standards, were available less frequently with levels of accuracy and bias that differed from a colocated non-FRM or equivalent monitor. Using the soil constituent of PM2.5 (particles of aerodynamic particle diameter les...

Renal tissues from 208 human necropsies were observed histologically for disseminated intravascular coagulation (DIC). The tissues were stained with hematoxylin-eosin, Mallory's phosphotungstic acid hematoxylin (PTAH) and cationic ferric hydroxide colloid stabilized with cacodylate (Fe-Cac), and tested by immunoenzyme histochemical (IEH) reaction for fibrin-related materials (FRMs). The use of ...

Two major advances in real-time monitoring of fine particles were supported under this research. These include reducing the moisture content of the sampled ambient air so that the temperature of the device could be reduced from 50°C to 30°C, and developing an innova­ tive approach to account for the loss of semivolatile materials on the filter surface. The devices have the potential to provide ...

The aim of this study is to measure resources for R&D (research and development) at the regional level in Romania and also obtain primary data that will be important in making the right decisions to increase competitiveness and development based on an economic knowledge. As our motivation, we would like to emphasize that by the use of Super Fuzzy FRM model we want to determine the state of R&D ...

The US Environmental Protection Agency (EPA) has designated a handful of instruments as Federal Reference or Federal Equivalency Methods (FRM and FEM, respectively) for the monitoring of fine particulate matter (PM2.5). More commonly used for indoor exposure assessment studies are optical scanning devices such as the DustTrak (TSI) due to the their portability and affordability. It is recommend...

ed fingerprint for bandwidth saving. An ISP can deploy a source-controlled caching service in different PacketCloud sites located at stub networks. We adopt share cache architecture proposed in [24] for redundancy elimination, which has been used as a building block in redundancy-aware routing [2] as well. Every packet travels through two PacketCloud sites, one ingress site nearby the sender an...

ABSTRACT Although more than 5000 TESS Objects of Interest have been catalogued, no comprehensive survey the flare rates their host stars exists. We perform first all 2250 non-retired TOIs with 2-min cadence light curves to measure or place upper limits on rates. find 93 candidates orbit and frequency distributions. Across sample, ≤1.5R⊕ frequently do 1.5 < R< 2.75R⊕, 2.75 4R⊕, R≥ ...

Abstract Conflicting interests in flood risk management (FRM) frequently arise, resulting disputes which are often resolved through mutual agreement. Nevertheless, a small number of cases require legal intervention when negotiation or mediation fails. This can publicly reveal the conflict hidden these agreements. The two areas that intersect to create this spatial planning and reduction strateg...
