Intelligent Interactive Simulator for the Training of Station Operators

Funding:

Implementation Period: 2009 - 2011

Description: The objective of this project is to develop an interactive game system for training, capacity building and qualification of operators who will work in substations and power plants of the National Interconnected System. The system will be equipped with three-dimensional graphic realism, interaction through smart-board and multimedia system, and an intelligent system for automatic generation of study situations, and operator score. A new event will be generated automatically without the operator knowing beforehand which event it will be. Then the operator will interact with the simulator to solve the presented problem. Realism will be imposed by the simulator through a 3D visual interface (operation panels, field equipment, equipment cubicles, etc.) generated for each one-line diagram unit. The stress situation imposed by the problem should be simulated. The operator's physical displacement time should also be considered in the executed maneuvers. In the end, a report should be generated quantitatively and qualitatively illustrating the operator's performance. The simulator must have an intelligence module based on a knowledge base that should be easily updatable by experienced operators. Thus, there will be accumulated knowledge stored in the base so that generated situation will be compatible with real ones, as well as make it possible to draw a real time sequence of actions expected by the operator, according to the actions he has already taken. Therefore, it will be possible not only to assess the operator in pre-existent situations in the knowledge base, and identify through the report any new procedures that might eventually optimize the process.

Development of a Mini-UAV System for Gyro-Stabilized Imaging

Funding: Financer of Studies and Projects (Financiadora de Estudos e Projetos)

Implementation Period: 2010 - present

Description: In the last decade, there was a great effort for the development and use of Unmanned Aerial Vehicles for both military and civilian purposes. In Brazil, the number of projects is still relatively small compared to the diversity and demand for automated precision air surveillance systems that do not endanger the operator's life. The growth of our country, associated with security issues, border control, agricultural production and environmental controls, increasingly require the use of new technologies. On the other hand, there is little development of components and subsystems in Brazil for use in this type of vehicle. This makes us very dependent on foreign technology, which is subjected to control and export restrictions by these foreign governments. These are the main points that justify the proposal, led by UNB's and ITA's research groups - who have experience in such projects -, and the XMobots company is already testing products. It is believed that with the joining of these segments a final preliminary mass production unit prototype can be obtained. Its development should be compliant to the rules of experimentation with this type of aircraft in Brazil. More specifically, this project aims to develop a hand-launched Mini Unmanned Aerial Vehicle (MiniUAV) weighing less than 5 kg, with maximum linear dimension of 3.0 meters, minimum range of 20 km, flight endurance of at least 60 minutes and able to be transported, assembled and operated by a team of only 2 (two) people. The system should become a product of XMobots company, a partner in the consortium.

Advanced Technology Prostheses for Lower Limb Amputees

Funding: Financer of Studies and Projects (Financiadora de Estudos e Projetos)

Implementation Period: 2010 - present

Description: The project aims to provide solutions to improve the quality of life of lower limb amputees using robotic rehabilitation technology (R-LEG). In this instance, the project must generate two prototype prosthesis: one for above the knee amputees and one for below the knee amputees. From the perspective of human rehabilitation robotics, these devices should be active, ie, motorized, able to adapt to the user and be functional to the human gait with the aid of a sensory apparatus and processing based on models of gait, requiring minimal intervention by the user. The results should be achieved based on research carried out at the University of Brasilia in the last five years. In this context, the research will be directed to the development of functional prosthesis, that is, ones that can be used by patients who must undergo rehabilitation protocols.Therefore, this project provides means to simplification and independence in activities of everyday life by lower limb amputees. Increased mobility should encourage greater educational, social and productive inclusion, contributing to improved accessibility to transport services, buildings and circulation areas. It should contribute to the treatment and rehabilitation of lower limb amputees. The project will allow for adjustments in order to suit a wide range of users (universal design). Upon becoming a product, there will be a worldwide market.

Modeling, Construction and Characterization of an Organic Single Electron Transistor

Funding: CNPq

Implementation Period: 2008 - 2010

Description: The objective of this project is to be able to bring together areas such as physics, chemistry and electrical engineering around a common goal, the development of quantum devices. These devices operate based on principles such as the Coulomb blockade and are strong candidates for the manufacture of ultra-low power, high density devices integrated circuits. However, despite the advancement of research on this subject, silicon and / or other inorganic semiconductors (GaAs, InGaAs, AlGaAs, InP) are still used as material. The use of sophisticated and expensive equipment, such as epitaxial growth techniques and photolithography, is required when these inorganic semiconductors are used. Also, these materials are hard (not flexible) and brittle and cannot, for instance, be deposited on a plastic surface, which is light and flexible, and which is also a low cost material. For example, the construction of an antenna that can adapt to the physical form of a satellite or aircraft is desirable to minimize the effects of friction. Plastic fibers are already being used in some cases to replace the glass optical fibers. Therefore, the use of plastics (organic polymers) in place of inorganic materials for manufacturing of microelectronic devices is growing popular due to the discovery of electrical conductivity of polymers in the 70's.In this light, our challenge will be modeling, construction and characterization of a quantum structure using organic and polymeric materials in the process.

Embedded System Supported by Linux Kernel for IPTV QoS Measuring

Funding: Foundation for Research Support of the Federal District (Fundação de Apoio à Pesquisa do Distrito Federal)

Implementation Period: 2009 - 2010

Description: The objective of this project is to design and implement a prototype for digital microprocessor-based instrumentation for the evaluation of IP links where DTV signals travel. This instrument aims at measuring the parameters of QoS (Quality of Service) in the lines used by telecom operators for data traffic and high-speed video typically used to provide Internet service in connections known as broadband and, recently, Digital TV services (pilot projects). In addition to providing voice and data services, telecom operators want to offer video service and best cost / benefit technology today is IPTV. Hence, the need to measure a series of parameters for QoS (Quality of Service), test the current data links and check if they are suitable for packet traffic IPTV that require broader bandwidth frequencies. The existing metallic pairs in today's network operators are not always suitable for transporting high frequencies and therefore it is critical to test the lines and the IPTV service. The IPTV software module will be part of a microprocessed-based, Linux Kernel (free software) supported product. This will be the first completely national product capable of implementing the following tests on IPTV services: - measurement of the quality of the video signal (QoS), both in broadcasting and unicasting (also known as VoD-Video on Demand) - emulation of a set-top box (STB) - show the actual image that is being received using MPEG-2 and MPEG-4 decoding; Among the measures taken are: - error indicator; - packet loss; - IGMP latency, - packet jitter; - PCR Jitter; - loss of synchronism; - total IP packets transmitted and received; - total packet of video; - IP rate; - video stream rate; the product proposed in this project is impo.
