1. Evaluation of grinding circuits for iron ore
Abstract Grinding has become one of the most important unitary operations for producing pellet feed for direct reduction from low-grade ores and small liberation size, such as compact itabirites. The aim of this study was to evaluate and compare two grinding circuits in an industrial iron ore plant, by evaluating the current operation through sampling, indus

2. Implementação e analise de uma abordagem de busca orientada por restrições atraves de heuristicas baseadas na folga para plantas multiproposito operando em batelada / Implementation and analysis of a constrained based search approach by means of the slack time heuristic for multipurpose batch plants
The problem considered is short term scheduling of batch chemical plants. Constraints over plant capacity are taken as intermediate storage constraints since they are frequent in the process industries area. The proposed approach using time windows utilizes a constraint based search technique based on the competiton of operations and bottleneck identificatio

3. Experimental tests unisng static mixers / Ensaios experimentais com misturadores estaticos
Mixing is a unit operation with applicability in many industrial fields, such as food, chemical, petrochemical, beverages and pharmaceutical, just to say some fields. The static mixers appear with an alternative to the traditional agitated vessels. They could be used such in batch mixing operation as in continuous processes, but mainly in continuous processe

4. Study of quantum decoherence and dissipation, during a two qubits temporal evolution controlled by unitary operations / Estudo da decoerência e da dissipação quântica durante a evolução temporal de dois qubits ditadas por operações unitárias controladas
Nessa dissertação, abordamos o problema de dois qubits interagindo com campos externos e entre si controladamente, de acordo com um Hamiltoniano considerado realista para implementação da porta lógica quântica XOR. Introduzimos acoplamentos entre as observáveis do sistema de dois qubits e um banho de osciladores harmônicos a fim de tratarmos o proble

5. Logic functions of the genomic cis-regulatory code
cis-regulatory modules that control developmental gene expression process the regulatory inputs provided by the transcription factors for which they contain specific target sites. A prominent class of cis-regulatory processing functions can be modeled as logic operations. Many of these are combinatorial because they are mediated by multiple sites, although o
