Solar Performance Metrics in Urban Planning: A Review and Taxonomy

open access: yesBuildings, 2022
Metrics are instrumental in design assessments. Solar performance metrics help designers to evaluate solar access in cities. Metrics should be used early in the urban planning stages in order to enable sustainable urban development with greater access to

Rethinking Poverty Metrics: Constructing the GEAR Model Indicators through a Reflective-Critical Lens [PDF]

open access: yesApplied Research in Administrative Sciences
The apparent success of many poverty reduction policies stands in sharp contrast to persistent experiences of dependency, clientelism, and structural vulnerability.

Objective functions used as performance metrics for hydrological models: state-of-the-art and critical analysis

open access: yesRBRH, 2020
Hydrological models (HMs) can be applied for different purposes, and a key step is model calibration using objective functions (OF) to quantify the agreement between observed and calculated discharges.

ABOVEGROUND BIOMASS ESTIMATION USING RECONSTRUCTED FEATURE OF AIRBORNE DISCRETE-RETURN LIDAR BY AUTO-ENCODER NEURAL NETWORK [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Aboveground biomass (AGB) estimation is critical for quantifying carbon stocks and essential for evaluating carbon cycle. In recent years, airborne LiDAR shows its great ability for highly-precision AGB estimation.

Evaluation of Power Systems Resilience to Extreme Weather Events: A Review of Methods and Assumptions

open access: yesIEEE Access, 2023
The requirement for a sustained supply of electricity intensifies during and in the aftermath of extreme events. In the past, events were considered extreme based on their extensive and devasting impacts and also because they were rare.

Some rigidity results on critical metrics for quadratic functionals [PDF]

open access: yes, 2014
In this paper we prove rigidity results on critical metrics for quadratic curvature functionals, involving the Ricci and the scalar curvature, on the space of Riemannian metrics with unit volume. It is well-known that Einstein metrics are always critical

Critical metrics of the volume functional on manifolds with boundary [PDF]

open access: yesProceedings of the American Mathematical Society, 2017
The goal of this article is to study the space of smooth Riemannian structures on compact manifolds with boundary that satisfies a critical point equation associated with a boundary value problem. We provide an integral formula which enables us to show that if a critical metric of the volume functional on a connected n n -dimensional ...

Apparent horizons in simplicial Brill wave initial data [PDF]

open access: yes, 1998
We construct initial data for a particular class of Brill wave metrics using Regge calculus, and compare the results to a corresponding continuum solution, finding excellent agreement. We then search for trapped surfaces in both sets of initial data, and

On the volume functional of compact manifolds with boundary with constant scalar curvature

open access: yes, 2008
We study the volume functional on the space of constant scalar curvature metrics with a prescribed boundary metric. We derive a sufficient and necessary condition for a metric to be a critical point, and show that the only domains in space forms, on ...
