Multi-Criteria-Optimisation and Desirability Indices [PDF]

open access: yes, 1999
The basic ideas of Desirability functions and indices are introduced and compared to other methods of multivariate optimisation. It is shown, that gradient based techniques are not in general appropriate to perform the numerical optimisation for ...

Harmonizing the Pyrene and Ether Groups in Covalent Triazine Polymers for Highly Effective H2O2 Photosynthesis via One‐Step Two‐Electron Oxygen Reduction

open access: yesAdvanced Functional Materials, EarlyView.
The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

Ultrahigh‐Yield, Multifunctional, and High‐Performance Organic Memory for Seamless In‐Sensor Computing Operation

open access: yesAdvanced Functional Materials, EarlyView.
Molecular engineering of a nonconjugated radical polymer enables a significant enhancement of the glass transition temperature. The amorphous nature and tunability of the polymer, arising from its nonconjugated backbone, facilitates the fabrication of organic memristive devices with an exceptionally high yield (>95%), as well as substantial ...

Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres

open access: yesAdvanced Functional Materials, EarlyView.
MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

The Desirability of Workfare as a Welfare Ordeal – Revisited [PDF]

open access: yes
In this paper we challenge the conventional wisdom that using workfare as a supplementary screening device to means-testing is socially undesirable when the government objective is welfarist, namely, to ensure that all members of society will attain some

High‐Rate FA‐Based Co‐Evaporated Perovskites: Understanding Rate Limitations and Practical Considerations to Overcome Their Impact

open access: yesAdvanced Functional Materials, EarlyView.
Vacuum‐based deposition is promising for perovskite solar cells to be successfully commercialized. However, co‐evaporation, the most common vapor phase deposition technique, suffers from very low deposition rates. In this work, we reveal that high deposition rates can lead to carbon flakes depositing into the perovskite absorber layers due to material ...

Starch/polyester films: simultaneous optimisation of the properties for the production of biodegradable plastic bags

open access: yesPolímeros, 2013
Blends of starch/polyester have been of great interest in the development of biodegradable packaging. A method based on multiple responses optimisation (Desirability) was used to evaluate the properties of tensile strength, perforation force, elongation ...

Do Supervisors Affect the Valuation of Public Goods? [PDF]

open access: yes
Systematic supervision procedures have been proposed to improve contingent valuation surveying, particularly in developing countries. Surprisingly, the CV literature does not say much about the potential effects of supervision even though there is ...

Proposal to draft a bill for the MEC Welfare: subsidizing and monitoring welfare NGOs [PDF]

open access: yes, 1998
This draft research report, and supporting documentation, explain the desirability for drafting a seventh bill to add to the present bundle of six bills for the MEC Welfare.
