Thin Film Resonators and Filters 1
This and the following paper deal with resonators and filters for use in wireless systems. The trend in wireless systems is to push for higher frequencies and wider bandwidths. System architectures are increasingly using digital signal processing which moves DSP towards the higher frequencies

Analysis of Heavy Metals in Aerosols on Air Filters (.pdf)
Measurement of heavy metals in aerosols on air filters is demonstrated. Simple linear empirical calibration is discussed, and performance is shown, for measurement precision and typical detection limits. Wear Metals in Lubricating Oil. EDXRF APPLICATION NOTE. ANALYSIS OF HEAVY METALS. IN AEROSOLS

Using Digital Potentiometers to Design Low-Pass Adjustable Filters
own set of filter requirements (i.e., settling time, fast transition region, etc.). Consequently, a variety of filters may be required in the circuit prior to the multiplexer. Usually these filters are implemented with operational amplifiers (op amps) in combination with fixed resistors

Improved Bulk Wave Resonator Coupling Coefficient For Wide Bandwidth Filters
Resonator coupling coefficient plays a key role in determining the bandwidth of acoustically or electrically coupled resonator filters. This paper presents a method using high mechanical impedance electrodes to increase the effective coupling coefficient for bulk acoustic wave (BAW) resonators

Fuel Analysis: Water Detection in Jet Fuel, Diesel Fuel, and Gasoline
Fuel analysis is very important part of the refining process. By continuously monitoring the free water and suspended solids in fuels, operations can immediately detect inefficiencies or failures in filters, coalescers and separators and possible contamination from other sources. Jet Fuel

Part II: Organoclays Improve Performance of Pump and Treat Remediation Systems
that activated carbon is used only in a backup mode, ensuring that any contaminants left in the effluent are in trace quantities that are non-detectable. Organoclays also have been used successfully as pre-polishers for ion exchange resins, membrane filters and air strippers, all of which are susceptible
