Using otsu's threshold selection method for eliminating terms in vector space model computation
(2013-12-01)
Visualization techniques have proved to be valuable tools to support textual data exploration. Dimensionality reduction techniques have been widely used to produce visual representation of document collections. Focusing ...
Computer tools to aid the learning and design steps for photovoltaic systems
(2011-12-28)
This paper presents novel simulation tools to assist the lecturers about learning processes on renewable energy sources, considering photovoltaic (PV) systems. The PV behavior, functionality and its interaction with power ...
Supporting multiple persistence models for PaaS applications using MDE: issues on cloud portability
(Institute for Systems and Technologies of Information, Control and Communication - INSTICCLisbon, 2015-05)
In cloud computing, lock-in refers to the difficulty of porting an application from one platform to another. An example of such difficulty can be witnessed when porting an application from Platform-as-a-Service Google App ...
Computational tool to support design of DAC Converter model AD7528 with the object code in XML
(2012-12-01)
Based on literature review, electronic systems design employ largely top-down methodology. The top-down methodology is vital for success in the synthesis and implementation of electronic systems. In this context, this paper ...
Modeling of a MIT for the application of a frequency inverter of the electric vehicle
(2011-12-01)
Nowadays, drives that use a combination of induction motors and frequency inverters are very common, a fact due to the financial practicality and viability in purchasing and operating that system. This system modeling and ...
Interaction between wave and coastal structure: Validation of two lagrangian numerical models with experimental results marine 2011
(2011-12-01)
Numerical modeling of the interaction among waves and coastal structures is a challenge due to the many nonlinear phenomena involved, such as, wave propagation, wave transformation with water depth, interaction among ...
Three-dimensional modeling and highly refined mesh generation of the aorta artery and its tunics
(2013-04-08)
This paper describes strategies and techniques to perform modeling and automatic mesh generation of the aorta artery and its tunics (adventitia, media and intima walls), using open source codes. The models were constructed ...
Improvement and evaluation of the MS2SV for mixed systems design described in abstraction high level
(2012-12-01)
This paper presents an important improvement of the MS2SV tool. The MS2SV performs the translation of mixed systems developed in MATLAB / Simulink for a structural or behavioral description in VHDL-AMS. Previously, the ...
