“…ALCA studies can be scoped at many different levels to provide focussed guidance for different purposes and decision-takers without excessive distraction by remote consequences beyond the influence of the immediate product or its producers. Yang [33,34] argues that all LCA is essentially consequential. (somewhat ignoring the use of LCA to simply gauge environmental performance for market competitive reasons (Ecolabels) or to provide data for Environmental Product Declarations (EPD's).…”

Marginally Adjusted Average LCA - Bridging the Gulf Between Attributional and Consequential LCA

Life Cycle Assessment (LCA) can often reveal unexpected or perverse outcomes from environmental initiatives.There are two main approaches to LCA: Attributional (ALCA) typically measures the impacts arising from producing a functional unit of product from average market suppliers and technologies. Consequential (CLCA) measures the marginal impacts to produce an additional functional unit of product, assuming that the resources consumed will come from new marginal supplies/technologies. As a result, ALCA and CLCA studies can give very different outcomes. The choice of method used for different LCA applications has divided practitioners and gives conflicting advice to decision-takers. The premise of this paper is that new production only causes marginal technologies to enter a market if the new producer specifically contracts the new marginal technology resources (e.g. Google sponsoring Solar Power for its operations). If the producer still purchases resources from average markets, then it is the aggregate demand in each market that motivates the entry of new marginal technologies and the effects of any addition should be shared with all co-consumers. The additional resources consumed are really the marginally adjusted average (MAA), not just the marginal. CLCA MAA results will usually closely resemble ALCA results, because entire markets are usually only perturbed to a small degree to meet new demand. In rare cases, where the existing market is substantially perturbed by an added demand, the CLCA results will differ significantly from the ALCA results. Many advantages are given for use of MAA to assess CLCA impacts, not least being to diminish the controversy between ALCA and CLCA outcomes.

“…In other equalizers, the technology of transmission line and parallel resonant structure are employed to obtain expected amplitude compensation. [4][5][6] It should be noted that the periodic response introduced by the inherent resonant structure usually deteriorates the suppression in the stopband.…”

“…A great many of synthesis methods for passive equalizers have been reported in recent years. [1][2][3][4][5][6] In Ran et al, 1 multistage RLC resonator is used to construct lumped equalizer in transmitter system, and multiple peaks in transmission response are inhibited. In Peng et al, 2 by depositing tantalum nitride (TaN) layer instead of metal layer on the substrate integrated waveguide (SIW), a kind of millimeter wave equalizer is proposed, whose equalizing value is dominated by the surface resistance.…”

A new method for designing multifunctional low‐pass filter with controllable equalizing capability is presented in this letter. By constructing the novel unit cell, namely, loading surface mount resistor on the grounded spoof surface plasmon polaritons (SSPPs), the filter not only achieves filtering and equalizing functions at the same time, but also improves the equalizing response in the low‐band effectively. To illustrate the principle, the extraction method of equivalent circuit of the lossy unit cell is introduced, and the equalization and filtering properties characterized by attenuation constant and asymptotic frequency are explored. To verify the concept, a prototype operating from 0.5 to 3.4 GHz with 10 dB equalizing value is implemented, fabricated, and measured. Good agreement is achieved between simulation and measurement. The result shows that the filter is provided with a smooth equalizing curve at the low frequency of the passband compared with the ungrounded SSPPs.

“…At that earlier time, SIMS oxygen depth profiles indicated a very low oxygen level in our films (< 1 x 10 18 cm -3 ), However, SIMS profiles taken on other films, deposited at other times using identical deposition conditions, can show significantly higher contamination levels. From an earlier study -3 relating to a-Si:H, oxygen levels exceeding 1-2 x 10 19 cm would be expected to significantly affect device performance (21). We are currently installing purifiers on the H 2 gas lines to the deposition system.…”

We report the deposition of improMd hydrogenated amorphous silicon germanium (a-SiGe:H) films by the Hot Wire CVD (HWCVD) technique using a tantalum filament operating at a low temperature. We gauge the material quality of the.* SiGe:H films by comparing infrared, small angle x-ray scattering (SAXS), photocapacitance and conductivity measurements to earlier results, and fabricate single junction ni-p solar cell devices using these i-layers.
