BACKGROUND Mental health problems such as depression are common in primary care settings and patients with chronic medical problems are at an increased risk. This co-morbidity suggests that district nursing services are particularly likely to encounter psychological problems in their patients. Mental health problems are poorly recognised and inadequately treated in primary care. In part this ma...

Microelectromechanical system (MEMS) development has become an active area for research in over the last decade. This area has advanced rapidly in recent years due to the potential ability of MEMS devices to perform complex functions in a smaller area. There is also the prospect to develop devices that can (1) be easily manufactured, (2) offer low power consumption, and (3) reduce waste. Especi...

Photoacoustic computed tomography (PACT) combines the optical contrast of imaging and penetrability sonography. In this work, we develop a novel PACT system to provide real-time imaging, which is achieved by 120-elements ultrasound array only using single data acquisition (DAQ) channel. To reduce channel number DAQ, superimpose 30 nearby channels’ signals together in analog domain, shrinking 4 ...

During the year 2010 the HADES Upgrade project has been finalized and the spectrometer has been commissioned in three test beam times at the end of the year. The HADES upgrade program had the following main goals: (1) The installation of a new Resistive Plate Chamber (RPC) detector to increase the time resolution and granularity of the time-of-flight system at the lower polar angles (θ < 45). (...

This note describes R&D to be carried out on the data acquisition system for a calorimeter at the future International Linear Collider. A generic calorimeter and data acquisition system is described. Within this framework modified designs and potential bottlenecks within the current system are described. Solutions leading up to a technical design report will to be carried out within CALICE-UK g...

Data acquisition systems (DAQ) are a well-explored research domain. With increasing measurement resolution in time and space they grow and traditional approaches do not satisfy the needs anymore. The amounts of data become too big to be processed by adhoc systems. Eventually, a real-time approach is necessary when it comes to guarantee 24/7 availability service. Distribution is a common means t...

Two divide-and-conquer (DAQ) approaches for building multipole-based molecular electrostatic potentials of proteins are presented and evaluated for use in QM/MM calculations. One approach is a further development of the neutralization method of Bellido and Rullmann (J Comput Chem 1989, 10, 479-487) while the other is based on removing part of the electron density before performing the multipole...

Many applications in materials science, life science and process control would benefit from atomic force microscopes (AFM) with higher scan speeds. To achieve this, the performance of many of the AFM components has to be increased. In this work, we focus on the cantilever sensor, the scanning unit and the data acquisition. We manufactured 10 microm wide cantilevers which combine high resonance ...

This paper deals with the comparative study on the properties of Aluminium alloy (LM6-12%Si) castings in sand casting and Evaporative pattern casting (EPC) process. Thermocouples are used to measure the temperature of the casting during solidification. Signals from the thermocouples are connected to the DAQ (Data Acquisition Card) 6024E.The software development platform used for this applicatio...

Throughout RHIC Run-9 (polarized protons) and Run10 (gold), numerous modifications to the Baseband Tune (BBQ) system were made. Hardware and software improvements resulted in improved resolution and control, allowing the system to overcome challenges from competing 60Hz mains harmonics, other spectral content, and other beam issues. Test points from the Analog Front End (AFE) were added and con...
