Optical diffusion tomography (ODT) has recently found renewed interest by the scientific and medical community due to advances in imaging electronics, computer processing power, development of tumor marking dyes, and image reconstruction algorithms. The development of this technology may allow the use of near infra red and infra red light to image internal structures of tissue without the use o...

Tractor hydraulic power is used on a wide range of agricultural implements; however, the availability of operational hydraulic data at points other than full engine throttle position is limited. Operators could utilize this hydraulic data to maximize field efficiency and minimize machinery costs when determining suitable machinery for field operations. A field usable hydraulic test apparatus ca...

Analog-to-digital converters (ADCs) and digital-toanalog converters (DACs) play an important role in the design of data acquisition systems. ADCs are used to convert analog signals like the output from a temperature transducer, a radio receiver or a video camera into digital signals for processing. Conversely, DACs are used to convert digital signals back to analog signals. For example, the DAC...

The DISTO collaboration has built a large-acceptance magnetic spectrometer designed to provide broad kinematic coverage of multi-particle final states produced in pp scattering. The spectrometer has been installed in the polarized proton beam of the Saturne accelerator in Saclay to study polarization observables in the ~ pp → pK~ Y (Y = Λ,Σ or Y ) reaction and vector meson production (φ, ω and ...

This paper presents an innovative implementation of a data acquisition, which is able to communicate with a chest belt in order to obtain the heart rate value and accelerometer data from a EZ Chronos watch. The main goal of the work presented is to implement an embedded system, which can be used in various life assisted or medical applications. Keywords—Arduino; Internet of things; body sensor;...

In the paper concept of the measurement (based on the sampling of potential differences during one period of the measuring signal) for impedance tomography data acquisition is described. Proposal of elimination of influence of dc electrochemical potential on data acquisition system is given in the paper as well. Thus suggested method enables increasing the rate of measurement. Results of experi...

Autonomic Computing is an emerging computing paradigm used to create computer systems capable of self-management in order to overcome the rapidly growing complexity of computing systems management. To possess self-* properties, there must be mechanisms to support self-awareness, that is an autonomic system should be able to perceive the abnormality of its components. After abnormality is checke...

The paper presents an enhanced learning and training system in data acquisition. This new method is the result of an interactive process for enhancing the learning activities for the students. The system was built to meet a new concept: “integrated learning”, an approach that allows students to exercise their abilities in real applications. These applications are entirely specified, having well...

A scalable multichannel digital MRI receiver system was designed to achieve high bandwidth echo-planar imaging (EPI) acquisitions for applications such as BOLD-fMRI. The modular system design allows for easy extension to an arbitrary number of channels. A 16-channel receiver was developed and integrated with a General Electric (GE) Signa 3T VH/3 clinical scanner. Receiver performance was evalua...

The TRIUMF Weak Interaction Symmetry Test (TWIST) is an experiment to measure precisely the Michel parameters describing the energy and angular dependence of positrons emitted from the decay of polarized positive muons. The detector consists of a 2 Tesla superconducting solenoid containing 56 planar chambers for high precision tracking of the positrons through readout of some 4200 multihit TDC ...
