Model-Driven Data Acquisition in Sensor Networks
- IN VLDB
, 2004
"... Declarative queries are proving to be an attractive paradigm for interacting with networks of wireless sensors. The metaphor that "the sensornet is a database" is problematic, however, because sensors do not exhaustively represent the data in the real world. In order to map the raw sensor ..."

approximations with probabilistic confidences, significantly more efficient to compute in both time and energy. Utilizing the combination of a model and live data acquisition raises the challenging optimization problem of selecting the best sensor readings to acquire, balancing the increase in the confidence

"... The Spallation Neutron Source (SNS) beam loss monitor system uses VME based electronics to measure the radiation produced by lost beam. Beam loss signals from cylindrical argon-filled ion chambers and neutron detectors will be conditioned in analog front-end (AFE) circuitry. These signals will be di ..."

Therefore a bandwidth of 100kHz and dynamic range larger than 21 bits data acquisition system will be required for this purpose. Based on the evaluation of several commercial ADC modules in preliminary design phase, a 24 bits Sigma

Abstract Plant electrostimulation is a very efficient method for evaluation of biologically closed electrical circuits in plants. The information gained from plant electrostimulation can be used to elucidate and observe the intracellular and intercellular communication in the form of electrical signals within plants. Monitoring the electrical signaling in higher plants represents a promising method to investigate fast electrical communication during environmental changes. Here we discuss DC methods of plant electrostimulation and describe a new Charge Stimulation Method in plant electrophysiology. It is often convenient to represent the real electrical and electrochemical properties of biointerfaces with idealized equivalent electrical circuit models consisting of discrete electrical components. Biologically closed electrical circuits in plants can be investigated using the

The design of an acquisitional query processor for sensor networks
- In SIGMOD
, 2003
"... We discuss the design of an acquisitional query processor for data collection in sensor networks. Acquisitional issues are those that pertain to where, when, and how often data is physically acquired (sampled) and delivered to query processing operators. By focusing on the locations and costs of acq ..."
