1. Desenvolvimento de dispositivos bolométricos para detecção de radiação infravermelha distante = : Development of bolometric devices for far-infrared radiation detection / Development of bolometric devices for far-infrared radiation detection
This work has as a main goal the fabrication and characterization of thermal sensors, described as bolometrics, which are dedicated to detection of far infrared radiation. These sensors are fabricated using microfabrication techniques and the thin films are selectives to wet etching. These mechanical microstructures are formed on silicon wafers using a surfa

2. Estudo de viabilidade de integração de micro-lâmpadas incandescentes com filtros interferenciais. / Study of viability of integration of incandescent micro-lamps with interferometric filters.
In the present work was realized a study of the viability of integrating two optical devices: incandescent micro-lamps and interferometric filters with the intention of obtaining a single device with specific characteristics. The fabrication of these optical devices was made using dielectric materials, obtained by plasma-enhanced chemical vapor deposition (P

4. A service-oriented infrastructure for ecological niche modelling. / Uma infraestrutura orientada a serviços para a modelagem de nicho ecológico.
Ecological niche modelling combines environmental data and information about the occurrence of a species to obtain models to describe its probabilistic distribution in a region. Computational algorithms generate models based on the hypothesis that, if a species was found under the conditions which define its niche, then it may survive in any place which offe

5. Construction and evaluation of microsystems for flow analysis / Construção e avaliação de microssistemas para analise em fluxo
This work describes the construction, characterization and application of microsystems for flow analysis. Laser ablation was employed for the development of a system in poly(methylmethacrylate), whose channels, with rectangular cross sections measuring 200 mm width by 4,5 mm depth, were sealed with an adhesive plastic film. This device supported flow rates u

7. Analogic memories characterization implemented with floating gate MOS transistors / Caracterização de memorias analogicas implementadas com transistores MOS floating gate
Monolithic integration of memories and analog circuits ,in the same die offers interesting advantages like: smaller application boards, higher robustness and mainly lower costs. Today, a profitable integration of these kind of circuit can only be possible using conventional CMOS technology, which allows efficiently extraordinary levels of integration. Thus,

9. Single-chip mechatronic microsystem for surface imaging and force response studies
We report on a stand-alone single-chip (7 × 10 mm) atomic force microscopy unit including a fully integrated array of cantilevers, each of which has an individual actuation, detection, and control unit so that standard atomic force microscopy operations can be performed by means of the chip only without any external controller. The system offers drastically
