1. Investigation of the effect of nozzle design on rheological bioprinting properties using computational fluid dynamics
ABSTRACT Bioprinting is the utilization of techniques derived from three-dimensional printing to generate complex biological structures which may replace natural tissues or organs. It employs high spatial resolution deposition of different cell types, growth factors and biomaterials. Those together form bioinks, which are the bioprinting inputs, analogously

2. Técnicas de otimização bi-objetivo para a determinação da estrutura de modelos NARX
The system identification aims to obtain a mathematical model that describes the behavior of a dynamic system from measurements. There are some typical steps in the process of building mathematical models from data: i) tests realization and data collection, ii) selection of the class of models, iii) structure detection, iv) parameters estimation and v) model

3. Improving the power consumption in pneumatic conveying systems by a daptive control of the flow regime
The pneumatic conveying of solids in a gas stream is a recurrent process in petrochemical industries. However, due to practical limitations the majority of existing systems have capacities ranging from 1 to 400 tones per hour over distances less than 1000 m, mainly because of a high power consumption per transported unit mass. More specifically, to avoid the

4. Estudo das estruturas de membrana: uma abordagem integrada do sistema construtivo, do processo de projetar e dos métodos de análise / Study of membrane structures: an integrated approach of the constructive system, design process and analysis methods
Membrane structures used in roofs are constructive systems formed mainly by structural membrane, which has also the function of sealing. Structural membranes are flexible sheets that resist to external loads due to their form, to their physical characteristics and to their pre-stressing. The pre-stressing of the membrane can be achieved either through its st
