The construction of the fluorescence detectors (FDs) of the Telescope Array (TA) experiment have been completed in June 2007, and the stereo observation have been started in June 2007. In this paper, we describe the development of the data acquisition (DAQ) system for the TA FD observations. The DAQ system of each TA FD station is comprised of 16 CPUs: 13 for controls of the FD front-end electr...

This study compares adults with and without attention deficit hyperactivity disorder (ADHD) on measures of direct and displaced aggression and illicit drug use. Three hundred ninety-six adults were administered the Wender Utah Rating Scale, the Risk Behavior Assessment, the Aggression Questionnaire (AQ), and the Displaced Aggression Questionnaire (DAQ). Those with ADHD were higher on all scales...

This study aimed to assess and compare the extent and pattern of psychosocial dysfunction and family burden in schizophrenia and obsessive-compulsive disorder, and to identify interrelationships between the two variables in these two disorders. First-degree relatives/spouses of 35 schizophrenic and 30 OCD patients were interviewed using the Dysfunction Analysis Questionnaire (DAQ) and the Famil...

The tensile properties of materials, such as the ultimate tensile strength, yield strength, elongation and elastic modulus, are very important factors for engineering designs. However, it is not easy for students to understand and evaluate the tensile properties of materials. In this study, a small and handy tensile testing machine was designed to help students conduct tensile tests in class us...

In measuring systems applying a digital measuring algorithm, the measurement process is divided into two stages: Stage 1 consists in the acquisition and storage of the system’s input data, based on which the value of the measurand is estimated in stage 2. The uncertainty of the stored data is translated into the uncertainty of the result of the estimation, i.e. of the result of the measurement....

Data acquisition (DAQ) is an important component in many fields. It typically involves the sampling of multiple analog signals, and converting them into digital formats so that they can be processed. DAQ systems also involve microprocessors, microcontrollers, digital signal processing, and/or storage devices. Many multi-channel DAQs, which utilize some sort of processing for simultaneous input ...

Achieving real-time photoacoustic (PA) tomography typically requires multi-element ultrasound transducer arrays and their associated multiple data acquisition (DAQ) electronics to receive PA waves simultaneously. We report the first demonstration of a photoacoustic tomography (PAT) system using optical fiber-based parallel acoustic delay lines (PADLs). By employing PADLs to introduce specific t...
