Efficient coordination of top-down and bottom-up models for energy system design: An algorithmic approach [PDF]

open access: hybridEnergy, 2023
To account for endogeneity effects in, e.g., energy demand, modern bottom-up energy system models are often linked to a top-down model describing the macroeconomic system. Solving such linked models involves iteratively passing solutions from one model to the other and vice versa until convergence is reached, which can be computationally demanding ...

How to Design Trade Agreements in Services: Top Down or Bottom Up? [PDF]

open access: greenSSRN Electronic Journal, 2013
This article deals with claims, recently raised in various circles, that structural faults in the General Agreement on Trade in Services (GATS) have prevented WTO Members from advancing services liberalization under the Agreement. The GATS is generally associated in this context with a bottom-up (positive-list) scheduling approach where the sectors on ...

“Top-down” and “bottom-up” strategies for wafer-scaled miniaturized gas sensors design and fabrication [PDF]

open access: goldMicrosystems & Nanoengineering, 2020
AbstractManufacture of large-scale patterned nanomaterials via top-down techniques, such as printing and slurry coating, have been used for fabrication of miniaturized gas sensors. However, the reproducibility and uniformity of the sensors in wafer-scale fabrication are still a challenge. In this work, a “top-down” and “bottom-up” combined strategy was

Bottom-Up and Top-Down Approaches for the Design of Neuromorphic Processing Systems: Tradeoffs and Synergies Between Natural and Artificial Intelligence [PDF]

open access: greenProceedings of the IEEE, 2023
While Moore's law has driven exponential computing power expectations, its nearing end calls for new avenues for improving the overall system performance. One of these avenues is the exploration of alternative brain-inspired computing architectures that aim at achieving the flexibility and computational efficiency of biological neural processing ...

Top-down design of magnonic crystals from bottom-up magnetic nanoparticles through protein arrays [PDF]

open access: greenNanotechnology, 2017
We show that chemical fixation enables top-down micro-machining of large periodic 3D arrays of protein-encapsulated magnetic nanoparticles (NPs) without loss of order. We machined 3D micro-cubes containing a superlattice of NPs by means of focused ion beam etching, integrated an individual micro-cube to a thin-film coplanar waveguide and measured the ...

Integrating top–down and bottom–up approaches to design global change adaptation at the river basin scale [PDF]

open access: greenGlobal Environmental Change, 2015
The high uncertainty associated with the effect of global change on water resource systems calls for a better combination of conventional top-down and bottom-up approaches, in order to design robust adaptation plans at the local scale. The methodological framework presented in this article introduces bottom-up meets top-down integrated approach to ...

Data-driven discovery of organic electronic materials enabled by hybrid top-down/bottom-up design

open access: greenAdvanced Materials, 2022
The high-throughput molecular exploration and screening of organic electronic materials often starts with either a 'top-down' mining of existing repositories, or the 'bottom-up' assembly of fragments based on predetermined rules and known synthetic templates.

Decolonizing Philosophy of Technology: Learning from Bottom-Up and Top-Down Approaches to Decolonial Technical Design [PDF]

open access: hybridPhilosophy & Technology, 2021
AbstractThe decolonial theory understands that Western Modernity keeps imposing itself through a triple mutually reinforcing and shaping imprisonment: coloniality of power, coloniality of knowledge, and coloniality of being. Technical design has an essential role in either maintaining or overcoming coloniality.

Study of Top-down and Bottom-up Approaches by Using Design of Experiment (DoE) to Produce Meloxicam Nanocrystal Capsules [PDF]

open access: bronzeAAPS PharmSciTech, 2020
In order to investigate the correlation among energy input-related, drug-related, and stabilizer-related aspects for both top-down and bottom-up nanocrystal production, meloxicam nanosuspensions (NS) were produced by using three different methods (low-energy wet milling, high-pressure homogenization, and precipitation) and each method was optimized by ...

Developing a comprehensive and comparative questionnaire for measuring personality in chimpanzees using a simultaneous top‐down/bottom‐up design [PDF]

open access: greenAmerican Journal of Primatology, 2013
AbstractOne effective method for measuring personality in primates is to use personality trait ratings to distill the experience of people familiar with the individual animals. Previous rating instruments were created using either top‐down or bottom‐up approaches. Top‐down approaches, which essentially adapt instruments originally designed for use with
