14. On the evolution of remote laboratories for prototyping digital electronic systems
The design of digital electronic systems for industrial applications can benefit in many ways from the prototyping capabilities of field-programmable gate array (FPGA) platforms. This paper presents three evolutionary releases of an FPGA-based remote laboratory and discusses the didactical and technical motivations behind each release, aiming to reduce the o

15. Um sistema microcontrolado para o monitoramento on-line, in situ e remoto de pH, condutividade e temperatura de águas
A portable microcontrolled system is proposed to monitor conductivity, temperature and pH in on-line, in situ and remote way from a water reservoir faraway 200 m. The system comprises two modules: one for data reception (located in laboratory) and another for data acquisition/transmission (located near water reservoir). It uses a microcontroller and a transc

18. Characterization and discrimination of soils by their reflected electromagnetic energy.
The objective of this work was to verify if reflected energy of soils can characterize and discriminate them. A spectroradiometer (Spectral reflectance between: 400-2,500 nm) was utilized in laboratory. The soils evaluated are located in Bauru region, SP, Brazil, and are classified as Typic Argiudoll (TR), Typic Eutrorthox (LR), Typic Argiudoll (PE), Typic H

19. Arquitetura como interface para a informação: sobre a espacialização das tecnologias da informação rumo a práticas colaborativas
This study examines an intersection between the spatialization of information and CSCW - Computer Supported Collaborative Work. More specifically it is argued the possibility of influence of the spatial distribution of ICT (information and communication technologies) on the interactions between members of two remotely connected laboratories. Spatialization (

21. STUDY OF INVERSE METHODS IN REMOTE SENSING WITH LASER / Estudo de métodos de inversão em sensoriamento remoto com lasers
The Laboratory of Environmental Applications of Lasers at Ipen realizes a study about atmospherics properties, such as extinction and backscattering coecient. These coecients are estimated by an inverse method, whose estimate quality is dicult to measure. This work presents a method with good statistic approach to retrieval the same coecients. The new method
