The main objective of this study was to use infrared spectroscopy to identify vegetable oils used as raw material for biodiesel production and apply multivariate analysis to the data. Six different vegetable oil sources--canola, cotton, corn, palm, sunflower and soybeans--were used to produce biodiesel batches. The spectra were acquired by Fourier transform infrared spectroscopy using a univers...

This paper presents the development of a new prototype system for acquisition and analysis of the 3D mandibular movement. In Dental Medicine, the study of the mandibular movement is very important in oral rehabilitation treatments, since it allows the diagnosis of clinical pathologies in the temporomandibular joints and therefore, it helps medical doctors to select the most adequate treatment p...

An instrument for intraoperative sensing of surgeons’ hand tremor during vitreoretina l microsurgery has been developed. Real-time monitoring of tremor is useful to surgeons for purposes of training, adjustment of technique, monitoring of fatigue, and deciding when or whether to perform certain procedures. The instrument incorporates six inertial sensors (three accelerometers and three rate gyr...

In this paper, we present an inertial sensor-based touch and shake metaphor for expressive control of a 3D virtual avatar in a virtual environment. An intuitive six degrees-of-freedom wireless inertial motion sensor is used as a gesture and motion control input device with a sensor fusion algorithm. The algorithm enables user hand motions to be tracked in 3D space via magnetic, angular rate, an...

Wireless Visual Sensor Network (WVSN) is an emerging field which combines image sensor, on board computation unit, communication component and energy source. Compared to the traditional wireless sensor network, which operates on one dimensional data, such as temperature, pressure values etc., WVSN operates on two dimensional data (images) which requires higher processing power and communication...

An algorithm is described for recovering the six degrees of freedom of motion of a vehicle from a sequence of range images of a static environment taken by a range camera rigidly attached to the vehicle. The technique utilizes a least-squares minimization of the difference between the measured rate of change of elevation at a point and the rate predicted by the so-called elevation rate constmin...

Wireless sensor networks (WSNs) are networked embedded systems where each unit generally consists of the following six components: sensors, memory, power supply, processor, communication unit, and actuators. WSNs will provide the bridge between the Internet and the physical world due to their ability to observing and controlling the physical world in real-time. Since most of the current WSNs us...

A set of sensor nodes is the basic component of a sensor network. Many researchers are currently engaged in developing pervasive sensor nodes due to the great promise and potential with applications shown by various wireless remote sensor networks. This short paper describes the concept of sensor node architecture and current research activities on sensor node development at ICTCAS. 1 The Conce...
