Two-particle correlations in azimuthal angle and pseudorapidity in inelastic p + p interactions at the CERN Super Proton Synchrotron

Results on two-particle ΔηΔϕ correlations in inelastic p + p interactions at 20, 31, 40, 80, and 158 GeV/c are presented. The measurements were performed using the large acceptance NA61/SHINE hadron spectrometer at the CERN Super Proton Synchrotron. The data show structures which can be attributed mainly to effects of resonance decays, momentum conservation, and quantum statistics. The results are compared with the Epos and UrQMD models.ISSN:1434-6044ISSN:1434-605

New Object-Oriented PROGRES for Specifying the Conceptual Design Tool GraCAD

AbstractThis paper deals with the application of graph transformations for the specification of conceptual design tools. We show how the graph rewriting system PROGRES is used for specifying the graph part of the conceptual method for architects in which functional requirements of the building to be designed are elicited by means of graph structures. The consistency of the specified requirements and whether a design matches those requirements is verified with graph constraint checkers. We consider how the new object-oriented extensions of the PROGRES language, i.e. packages and node objects with redefinable methods can be used to achieve the required constraint monitoring and preserving functions in the form of graph checker objects. The prototype for our method, called GraCAD, is created with UPGRADE - the recently developed Java framework for developing visual applications based on a PROGRES specification, and the commercial system for architects ArchiCAD

GraCAD - Graph-Based Tool for Conceptual Design

This paper proposes a new methodology for computer-aided design of layouts of buildings. The presented methodology addresses the very early phase of designing that is called Conceptual Design. In this methodology the architect does not pay attention to layout details, but operates on functional requirements, constraints, and high-level architectural concepts such as functional areas and rooms. The GraCAD system realizes this methodology by adding a high-level design tool to the wellknown commercial program ArchiCAD. This design tool has been realized using graph-based knowledge representation techniques and graph grammars as offered by the system PROGRES. Preliminary results show that the developed ArchiCAD add-on and the formalism of graph grammars seems to be useful in aiding architectural design

Software Development for High Speed Data Recording and Processing

The European XFEL beam delivery defines a unique time structure that requires acquiring and processing data in short bursts of up to 2700 images every 100 ms. The 2D pixel detectors being developed produce up to 10 GB/s of 1-Mpixel image data. Efficient handling of this huge data volume requires large network bandwidth and computing capabilities. The architecture of the DAQ system is hierarchical and modular. The DAQ network uses 10 GbE switched links to provide large bandwidth data transport between the front-end interfaces (FEI), data handling PC layer servers, and storage and analysis clusters. Front-end interfaces are required to build images acquired during a burst into pulse ordered image trains and forward them to PC layer farm. The PC layer consists of dedicated high-performance computers for raw data monitoring, processing and filtering, and aggregating data files that are then distributed to on-line storage and data analysis clusters. In this contribution we give an overview of the DAQ system architecture, communication protocols, as well as software stack for data acquisition pre-processing, monitoring, storage and analysis
