A Modified Barrier and Barrier Method and the Optimal Power Flow Problem
(2017-01-01)
This work proposes an approach that uses a union of methods based on logarithmic barrier function and modified logarithmic barrier function for the resolution of the reactive optimal power flow problem. In this proposed ...
Barriers and opportunities for adapting to climate change on the North Coast of São Paulo, Brazil
(2017-08-01)
This paper examines barriers and opportunities for climate change adaptation in an urban coastal setting where adaptation is in its infancy. It draws on a diagnostic framework as a foundation for identifying and organising ...
Unfolding barriers for urban mobility plan in small and medium municipalities – A case study in Brazil
(2020-02-01)
This paper investigated barriers for the design and implementation of Urban Mobility Plans in small and medium-sized cities in the State of São Paulo, Brazil. To achieve this objective an exploratory survey was carried out ...
Interactive whiteboards in Brazilian's primary school: New barriers
(2015-01-01)
This article focuses on presenting the results from the research Barreiras para implementação da Lousa Digital Interativa: um estudo de caso, thus contributing to the systematization of knowledge about the implementation ...
Barriers faced by MSEs: evidence from Mozambique
(EMERALD GROUP PUBLISHING LIMITED, 2011)
Purpose - The purpose of this research is to shed light on the main barriers faced by Mozambican micro and small enterprises (MSEs) and their implications in respect to the support policies available for these enterprises. ...
Non-parabolic intergranular barriers in tin oxide and gas sensing
(American Institute of Physics, 2012-07-30)
Chemoresistive properties of crystalline solids strongly depend on the concentration of stoichiometric defects. In the case of tin oxide, oxygen vacancies are a case in point of such kind of defects. We address the problem ...
Tunnelling through two barriers
(Elsevier Science BvAmsterdamHolanda, 2005)
Barriers to the adoption of energy-efficient technologies in the building sector: A survey of Brazil
(2021-12-01)
The building sector is responsible for 51% of the electricity consumed in Brazil, and about 10% of the total greenhouse gas emissions. These numbers continue to grow, despite significant efforts made by the government to ...
Schottky-type grain boundaries in CCTO ceramics
(Pergamon-Elsevier B.V. Ltd, 2011-10-01)
In this work we studied electrical barriers existing at CaCu(3)Ti(4)O(12) (CCTO) ceramics using dc electrical measurements. CCTO pellets were produced by solid state reaction method and X-ray diffractograms showed which ...
Electroconvective flow induced by dielectric barrier injection in silicone oil
(Elsevier, 2013-01)
It has been demonstrated that dielectric barrier actuators can be used to induce electrohydrodynamics flows in air as well as in gas. These actuators are often called surface non-thermal plasma actuators in gas applications. ...
