In previous works the authors have shown the effectiveness implementing animal based strategies in a mobile robot in order to find an odour source in turbulent plumes. Since February 2002, he is in the position of researcher working on within silicon technology and integration of sol—gel process into silicon devices. The search strategy fuses with the information from gas sensors, wind direction sensor, ultrasound sensors, etc. This behaviour improves the global searching performance. Three navigation algorithms are compared with a simple gas sensor and with an electronic nose.
The electronic nose utilized is composed by an array of different and weakly selective metal oxide gas sensors. Their performance in finding an ethanol source in a room with obstacles is evaluated. The proceedings have been selected for coverage in:? It is well known that insects and other animals use olfactory senses in a wide variety of behavioural processes, namely to recognize and locate food sources, detect predators, and find mates. Then the sensed data is assimilated into an advection-diffusion model by means of a reduced order Kalman filter. Such sensors are composed of two main elements: the sensing layer and the transducer. It is well known that insects and other animals use their olfactory sense in a wide variety of behavioural processes, namely to recognize and locate food sources, detect predators, and find mates. In 2000, she was with the Department of Physics, University of Lecce, where she was involved in deposition of thin films making use of the pulsed laser deposition technique.
Some solutions that have been proposed and implemented in order to handle the identified issues will be presented. Describes the manufacturing process and properties of stannic oxide and concludes that with modern development in tin dioxide-based sensors their application is set to expand from their present role in domestic, commercial and industrial alarms to monitoring instruments as well. The results of this work can be used for example to coordinate a set of mobile environment monitoring agents in order to find sources of pollution or by a set of demining robots in order to find mined areas. He has been organiser and Chairman of International Conferences and Director of International Schools on Sensors and Microsystems. Long term stability measurements were also performed. The present work investigates the impact and the effectiveness of an information and communications technology platform able to allow the cognitive stimulation practice within a domestic environment. Preliminary results, achieved after the tests performed on patients with mild to moderate Alzheimer, demonstrates that the aforementioned platform is a very useful tool able to increase the neuropsychiatric and cognitive state of the patient.
Sol-gel-derived tin oxide thin films were used to fabricate gas sensor devices. The last strategy is based on odour map estimation and maximum concentration following. We give some procedures to implement the model, also illustrated through a practical example. Essentially, the robots act as a mobile, wireless node in a sensor network. The present work investigates the impact and the effectiveness of an information and communications technology platform able to allow the cognitive stimulation practice within a domestic environment.

He took his PhD in physics in 1989 at the University of Bari. The E-mail message field is required. A cheap nanofabrication process for titania TiO 2 polycrystalline nanowire array for gas sensing applications with lateral size ranging from 90 to 180 nm, and gas sensing characterizations are presented.
After leaving the source, a chemical plume becomes shred in small filaments by the effect of turbulence. She is also involved in the modelling of the electrical and sensing properties of nanosized metal oxides and biomimetic materials by electrical impedance spectroscopy, as well as in Pattern Recognition techniques for data analysis. This paper discusses the gathering of olfactive information and its utilization by a mobile robot to find a specific odour source in a room with turbulent phenomena and multiple sources of odour. Measurement and statistical models are then obtained from the associated concentration distribution. Increasingly sophisticated equipment is required for this monitoring, and development of that equipment and strategies for its use is a multi-disciplinary field involving chemists, analytical scientists and engineers. She researches the interactions between gases and mixed oxides and the electrical and optical characterization of thin films for organic and inorganic gas sensors. The inherent potential of such devices has led to growing interest worldwide in commercial fiber optic chemical and biosensors.
The former is the part that interacts directly with the analyte i. To this community of distributed agents it is called herein: SpreadNose. Optical Sensors for Biomedical Diagnostics and Environmental Monitoring is an essential resource for students, established researchers, and industry developers in need of a reference work on both the fundamentals and latest advances in optical fiber sensor technology in biomedical diagnostics and environmental monitoring. The odours are identified and quantified by a pattern recognition algorithm based on an artificial neural network. Luca Francioso received the M. Pietro Siciliano, physicist, senior researcher, received his degree in physics in 1985 from the University of Lecce.
He co-authored of more than 78 peer reviewed papers on national and international journals 1109 total citations by 80 documents; h-Index: 18 , 2 book chapters and several Communicationsto national and International Congresses as regular and invited talks. It covers a broad range of aspects, including: bio-, physical and chemical sensors; actuators; micro- and nano-structured materials; mechanisms of interaction and signal transduction; polymers and biomaterials; sensor electronics and instrumentation; analytical microsystems, recognition systems and signal analysis; and sensor networks, as well as manufacturing technologies, environmental, food and biomedical applications. Held in Lecce, Italy in February 2017, the event brought together researchers, end users, technology teams and policy makers. The book represents an invaluable and up-to-the-minute tool, providing an essential overview of recent findings, strategies and new directions in the area of sensor research. Since 2001, he works in the Institute for Microelectronic and Microsystems of the Italian National of Research Council C. The first navigation strategy is based on bacterial chemotaxis.
Her principal interests regard the electrical characterization of novel nanostructured materials for applications in chemical gas sensors and the development of innovative miniaturized devices based on multisensory systems for applications in the control of air quality and industrial combustion processes, food quality and safety, environmental monitoring, and breath analysis, a non-invasive approach for applications in frontier diagnostics. The mobile sensing agents employed in the experiments have self localization capabilities and carry an electronic nose and a thermal anemometer. The present work investigates the impact and the effectiveness of an information and communications technology platform able to allow the cognitive stimulation practice within a domestic environment. Some special cases of the time series model are considered. At present he works in the field of combustion control sensors with implementation of thin film based gas sensors and development of micromachining process of metal oxide layers.
Further, it addresses various aspects based on the development of new chemical, physical or biological sensors, assembling and characterization, signal treatment and data handling. The first problem to be solved is related to sense a chemical plume far away from the source. The problem is that once you have gotten your nifty new product, the sensors for environmental control siciliano pietro gets a brief glance, maybe a once over, but it often tends to get discarded or lost with the original packaging. The objective is to estimate the diffusion field of each different odour present in the environment. Gas-sensing tests carried out on the films deposited onto alumina substrates in the temperature range between 100 and 400°C showed that faster responses are obtained at temperatures higher than 250°C. . Two types of robots were designed, the DustClean robot to autonomously clean pedestrian areas, and the DustCart robot for door-to-door garbage collection.
