Correlations between EAS datasets recorded at very-distant (10.1000 km away) stations have been searched for. The stations, operated by the Large Area Air Shower (LAAS) group in Japan, are precisely synchronized by the GPS. Assuming some sporadic burst activities of UHE cosmic ray sources, we picked up coincident and parallel EAS events. From recent EAS data of six stations, we could not find any significant events.
This paper proposes a query language to consistently access metadata registries. In current, many metadata registries have been built in various fields. Unfortunately, there is no access method to access the metadata ...

This paper presents a new technique to determine the dynamic and frequency response of capnographs using a custom built 'EtCO2 simulator system'. Capnographs are devices that use CO2 from a patients' expired breath to monitor the cardiopulmonary status during anaesthesia and mechanical ventilation. Capnographs at present are routinely calibrated via a static calibration method only. The dynamic response of the capnographs is not accounted for. The frequency and time response are important as they determine if capnographs can be used in high frequency and pediatric ventilation schemes. Experiments performed using the method described in this paper proved that old capnographs usually do not satisfy the manufacturer quoted specifications for time and frequency response. Therefore, a routine check for capnographs is recommended. The method can also be used to verify manufacturer quoted specifications. The EtCO2 simulator system, designed and constructed simulates human respiration cycle. The gas sources used are 5% CO2 and room air that can be switched alternatively. Both supplies are pressure regulated and connected through non-return valves to electric valves. The valves are microprocessor controlled and the on/off time is user defined allowing a wide range of waveforms to be simulated. The output from the simulator is delivered to capnograph. Capnograms are captured by digital video recording. The captured video in 'avi' file format is then converted into individual frames. These frames are converted into digital data through image processing in Matlab. The data obtained is subjected to extensive analysis to determine the frequency and time response of the respective capnograph. Copyright 2005 ISA. All Rights Reserved.

Protein-protein interactions are strictly correlated to the surface shape because beside a large number of structural amino acids composing the core there are few superficial amino acids that define the functionality. This study concerns the development of a tool that starting from the 3D atomic coordinates of a protein, as retrieved from the protein data bank (PDB), models the macromolecular surface in an implicit way using an approach that is more suitable for this kind of analysis than the parametric one. The marching cubes algorithm is used to process the volumetric description of the protein obtaining a precise representation of the corresponding surface. Because of the large amount of data to consider in studying whole protein families, this algorithm is implemented in parallel on a computer cluster to improve its performance. The parallel version of marching cubes is developed in ASSIST, a high level structured parallel programming system, obtaining a near optimal performance considering computational activities, and acceptable performance including I/O.
