Multiarea optimal power flow using multiobjective evolutionary algorithm
(2009-12-17)
In this work the multiarea optimal power flow (OPF) problem is decoupled into areas creating a set of regional OPF subproblems. The objective is to solve the optimal dispatch of active and reactive power for a determined ...
Hypothesis testing in econometric models
(2015-12-11)
This thesis contains three chapters. The first chapter considers tests of the parameter of an endogenous variable in an instrumental variables regression model. The focus is on one-sided conditional t-tests. Theoretical ...
Estimating Sample Size for Usability Testing
(Universidad UTE, 2017)
Psychometric computational thinking test
(Association for Computing Machinery, 2018)
The recent widespread popularity of computational thinking (CT) has raised the need for a reliable method for assessing it. Recent CT tests focus on programming skills rather than the analytical ability and problem-solving ...
Integrated lot-sizing and cutting stock problem applied to the mattress industry
(2020-01-01)
In many productive processes, two important problems arise in the production planning: the lot-sizing problem and the cutting stock problem. Generally, companies deal with these problems separately but, by considering them ...
The desgner’s perception and expert’s evaluation: testing techniques for problem exploration on a design methodology framework

Addressing high dimensionality and lack of feature models in testing of software product lines
(Universidade Federal de PernambucoUFPEBrasilPrograma de Pos Graduacao em Ciencia da Computacao, 2016)
An improvement proposal for mismatch condition problem in dragon test system
(STI, 2018-06-15)
RF final test measurements include the DC to RF performance of components and are
therefore included on the system offsets measurements to compensate for the
deviations. The equivalent RF circuit of a test fixture involves ...
Integrating packing and distribution problems and optimization through mathematical programming
(Growing Science, 2016-10)
This paper analyzes the integration of two combinatorial problems that frequently arise in production and distribution systems. One is the Bin Packing Problem (BPP) problem, which involves finding an ordering of some objects ...
