UNDERSTANDING AND MODELING THE SORPTION ON ANION EXCHANGE RESINS USING POLY-PARAMETER LINEAR FREE-ENERGY RELATIONSHIPS AND PHASE CONVERSION
… relationships (pp-LFERs) and the feasibility of phase conversion (e.g., an ideal gas phase as the reference state) for ionic species was examined. To develop the model, a training set of isotherms was obtained using aliphatic and aromatic carboxylates, phenols, anilines, nitrobenzene, and …

Outphase power amplifiers in OFDM systems
… exists in conventional power amplifiers. The outphase amplifying concept overcomes this trade-off by enabling the use of high efficiency, non-linear power amplifiers for linear amplification. An amplitude modulated signal is first decomposed into two constant amplitude, phase modulated signals …

A thermodynamic simulation model for storage of corn
… modified Maxwell, and geometric mean). Five phase conversion factors(0.0, 0.25, 0.50, 0.75, and 1.0) were utilized to evaluate the five mixing models. Three laboratory storage bins, and eight grain sample columns were designed and constructed. Three experiments were conducted to enable the …

Integrated Signal Demodulation, Data Conversion, and Packaging Strategies for a Wireless, Fully Implantable, Bidirectional Neural Interface
… acquisition by developing an analog-to-digital conversion scheme that initially follows the Wilkinson architecture, in which the input sample is first converted into a time interval by measuring the discharge time of a capacitor, and this interval is subsequently digitized by a time- to-digital …

Lithium-ion Battery Devices as a Method of Doping Metal Halide Perovskites
… systems for the next generation of energy conversion devices studied today. Reports of record-breaking energy conversion efficiencies are disclosed on an almost yearly basis. However, unlike traditional inorganic semiconductors such as silicon and GaAs, the impact of inserting extrinsic …

Multi-scale chemistry modeling of the thermochemical conversion of biomass in a fluidized bed gasifier
The thermochemical conversion of biomass to fuels via syn-gas offers a promising approach to producing fungible substitutes for petroleum derived fuels and chemicals. In order for these fuels to be adopted, they must be produced in a cost-competitive way. Unfortunately, there exist a number of …

Cu2O thin films for p-type metal oxide thin film transistors
… to improve the carrier mobility in Cu2O without phase conversion, such as oxidation (CuO) or oxide reduction (Cu). In order to allow an in-depth discussion on the main origins of the very low carrier mobility in as-deposited films and the mobility enhancement by annealing, a quantitative analysis …

Reduced Receivers for Faster-than-Nyquist Signaling and General Linear Channels
… each data symbol. An improvement of the minimum phase conversion that sharpens the focus of the ISI model energy is proposed. When combined with a delayed and slightly mismatched receiver, the decoding allows a smaller M without significant loss in BER. The second part analyzes the effect of the …

Three-Phase Generation Using Reactive Networks
<p>Household appliances utilize single-phase motors to perform everyday jobs whether it is to run a fan in an air conditioner or the compressor in a refrigerator. With the movement of the world going “green” and trying to make everything more efficient, it is a logical step to start with the items …
