The MCU subsystem of the IceCube DAQ is the source that provides the capability to ascribe to each "hit" detected by any of the ~5120 Digital Optical Modules (DOM a time-stamp common to the entire IceCube = InIce + IceTop array. This common timestamp shall be referred to as IceCube Time Calibration (ITC). The creation of the ITC requires a complex sequence of information capture at both DOM and...

A LabVIEW-based self-constructed chemical virtual instrument (VI) has been developed for determining temperatures and pressures. It can be put together easily and quickly by selecting hardware modules, such as the PCI-DAQ card or serial port method, different kinds of sensors, signal-conditioning circuits or finished chemical instruments, and software modules such as data acquisition, saving, p...

The ALICE TRD Detector employs 1080 optical links for data readout. The FEE chips (TRAP [1]) form a readout tree running at 8 bit 120 MHz double data rate. The tracklet and raw data are sent over the Optical Readout Interface (ORI) at 2.5 Gbit/s. The Global Tracking Unit (GTU) serves as data receiver and fast track finder and contributes to the L1 trigger decision. Finally, after L2 accept the ...

During the last year, the HADES detector setup has been improved in order to achieve several goals, in particular to enhance the capability of the readout electronics [1] [2] (up to 10 events/s). This is required to enable HADES to cope with heavy ion beams at SIS18 and later at the SIS100 at FAIR. Here, one of the major changes of the DAQ upgrade was the replacement of the copper-based cables ...

( 1. I nstitute of Modern Physics,Chinese Academy of Sciences,LanZhou,730000,China, 2. University of Chinese Academy of Sciences ,Beijing,100039,China) Abstract: A large number of data need to be transmitted in high-speed between Field Programmable Gate Array (FPGA) and Advanced RISC Machines 11 micro-controller (ARM11) when we design a small data acquisition (DAQ) system for nuclear experiment...

OBJECTIVE To assess the frequency and causes of dental anxiety and their relation to irregular dental visits among adult dental patients. METHODS The Dental Anxiety Question (DAQ) included within a self-administered questionnaire was distributed to 1025 patients attending the Interns' Dental Clinics in the Department of Preventive Dental Sciences, College of Dentistry, University of Dammam, D...
