1. Heurística da Ancoragem na Decisão de Especialistas: Resultados Sob Teste de Manipulação
Resumo Embora as decisões auxiliadas pela tecnologia tenham avançado nos últimos anos, o processo de decidir ainda é uma atividade essencialmente humana. Variáveis pessoais do decisor ou de contexto interferem nesse processo, com destaque para a variável conhecimento, tendo, por isso, ocupado um lugar cada vez mais relevante na literatura, ao se buscar

2. Análise de confiabilidade de peças de madeira fletidas dimensionadas segundo a NBR 7190/97 / Reliability analysis of bending timber members designed according NBR 7190/97
A passagem do método das tensões admissíveis para o método dos estados limites na NBR 7190 - Projeto de Estruturas de Madeira, ocorrida em 1997, foi feita por meio de calibração determinística que teve como ponto central a resistência da madeira na compressão paralela às fibras. Um dos aspectos modificados foi o dimensionamento de peças fletidas n

3. Metodologia de controle de qualidade e implantação de campos padrões de radiação X, nível mamografia, seguindo a norma IEC 61267 / Quality control methodology and implementation of X-radiation standards beams, mammography level, following the standard IEC 61267
In this work it was developed and applied a quality control program of the Xradiation system (160 kV, constant potential, target of tungsten) of the Calibration Laboratory of IPEN(LCI) in the energy range relative to mammography beams (from 25 kV to 35 kV). The X radiation standards beams, level mammography, using molybdenum and aluminum as additional filtra

4. Reliability-based evaluation of design guidelines for cold-formed steel-concrete composite beams
This paper presents an analysis of design guidelines for steel-concrete composite beams, formed by concrete-filled cold-formed steel sections. The study is based on experimental results for connector resistance (push-out) and for four full-scale beam bending tests. The accuracy of analytical design equations is evaluated by comparing their predictions with e

5. Sequential and double sequential fission observed in heavy ion interaction Of (11.67 MeV/u)197Au projectile with 197Au target
The heavy ion interaction of 11.67 MeV/u 197Au + 197Au has been investigated using mica as a passive detector. By employing Solid State Nuclear Track Detection Technique the data of elastic scattering as well as inelastic reaction channel was collected. The off-line data analysis of multi-pronged events was performed by measuring the three-dimensional geomet

6. Reliability based calibration of partial safety factors of brazilian design codes / Aplicação de confiabilidade na calibração de coeficientes parciais de segurança de normas brasileiras de projeto estrutural
This study addresses the partial safety factors used in structural design codes. The study is based on the theory of structural reliability, which allows an explicit consideration of the uncertainties in material strengths and load actions, and results in a quantitative measure of structural safety: the reliability index. A calibration methodology is conside

7. Modelagem computacional de tomografia com feixe de prótons / Computational modeling of protons tomography
In the present work a preliminary research via computer simulations was made in order to elaborate a prior program for the first experimental pCT setup in Brazil. Proton therapy is a high precise form of a cancer treatment. Treatment planning nowadays is performed basing on X ray Computer Tomography data (CT), alternatively the same procedure could be perfor

8. Reliability analysis of I-section steel columns designed according to new Brazilian building codes
This paper presents an evaluation of the safety of I-section steel columns designed according to the new revision of the Brazilian code for design of steel buildings (NBR8800) and to the code for loads and safety of structures (NBR8681). The safety evaluation is based on structural reliability analysis of columns designed to comply with these codes, and on a

9. Caracterização do campo de nêutrons na instalação para estudo em BNCT no Reator IEA-R1 / NEUTRON FIELD CHARACTERIZATION IN THE INSTALLATION FOR BNCT STUDY IN THE IEA R1 REACTOR.
This work aims to characterize the mixed neutron and gamma field, in the sample irradiation position, in a research installation for Boron Neutron Capture Therapy (BNCT), in the IPEN IEA-R1 reactor. The BNCT technique has been studied as a safe and selective option in the treatment of resistant cancerigenous tumors or considered non-curable by the convention

10. Modelagem hidrológica dinâmica distribuída para estimativa do escoamento superficial em uma microbacia urbana
- Floods and inundations are serious problems in Brazilian cities as a result of inappropriate urbanization processes. Impervious surface reduces or makes water infiltration impossible, leading to significant increases in surface runoff. Considering this scenario, this work aims at applying a dynamic distributed hydrological model in order to estimate surfac

11. Fluxo hÃdrico subterrÃneo: modelagem computacional e calibraÃÃo iterativa dos parÃmetros hidrodinÃmicos. / Groundwater Flow: computation modeling and calibration of the parameters hydrodynamics
The current work presents a computer simulation of groundwater flow in the Cariri Valley, which is located in the State of CearÃ. The cities of Barbalha and MissÃo Velha are located inside this area. In order to perform the computer modeling the software Processing MODFLOW Pro was used. It was used both permanent and time dependent situations. Also both ra

12. Simulation groundwater flow in the region of the Cariri and calibration using hydraulic head gradient / SIMULAÃÃO COMPUTACIONAL DO FLUXO HÃDRICO SUBTERRÃNEO NA REGIÃO DO CARIRI E CALIBRAÃÃO UTILIZANDO GRADIENTE DAS CARGAS HIDRÃULICAS
The main objective of this research is to use a computer code to simulate groundwater flow in an area in the south of the state of Cearà situated between the cities of Crato, Juazeiro do Norte and Barbalha, in the âCaririâ Valley. The computer code used was MODFLOW, a 3-D finite difference groundwater flow model. Two different scenarios we simulated: the
