A preliminary analysis for determining passenger car equivalent value for motorcycle during first lost time and saturation time at pretimed signalized intersections [PDF]

E3S Web of Conferences
In Banda Aceh City, signalized intersections are a strategic approach to mitigate conflicts such as accidents and traffic congestion. This was achieved by efficiently managing the flow of vehicles passing through intersections, enhancing their overall ...

Adsorption and desorption of polycarboxylate ether superplasticizer in fresh cementitious materials blended with mineral admixtures

Journal of Materials Research and Technology, 2022
The adsorption behavior of polycarboxylate ether (PCE) superplasticizer in fresh cement-based materials has been well investigated, but its desorption behavior was little reported. To facilitate deeper understanding the dispersion effect of PCE on binder

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

The Usefulness of Core PCE Inflation Measures [PDF]

Finance and Economics Discussion Series, 2011
This paper examines a number of alternative PCE price inflation measures including overall PCE inflation, PCE inflation excluding food and energy, trimmed mean PCE inflation, component-smoothed inflation, variance-weighted inflation, inflation with weights based on disaggregated regressions, and survey measures of inflation expectations. When averaging
