Controls Optimization for Energy Efficient Cooling and Ventilation at CERN / Monteiro, Diogo (CERN) ; Barillère, Renaud (CERN) ; Bunijevac, Nikolina (CERN) ; Rühl, Ingo (CERN)
Cooling and air conditioning systems play a vital role for the operation of the accelerators and experimental complex of the European Organization for Nuclear Research (CERN). Without them, critical accelerator machinery would not operate reliably as many machines require a fine controlled thermodynamic environment. [...]

A Modular Approach to Develop Standardized HVAC Control Systems with UNICOS CPC Framework / Booth, William (CERN) ; Barillère, Renaud (CERN) ; Bes, Marcin (CERN) ; Blanco Vinuela, Enrique (CERN) ; Bradu, Benjamin (CERN) ; Quilichini, Marc (CERN) ; Zimny, Michal (CERN)
At CERN there are currently about 200 ventilation air handling units in production, used in many different applications, including building ventilation, pressurization of safe rooms, smoke extraction, pulsion/extraction of experimental areas (tunnel, cavern, etc), and the ventilation of the computing centre. The PLC applications which operate these installations are currently being revamped to a new framework (UNICOS CPC). [...]

Electroweak Measurements in Electron-Positron Collisions at W-Boson-Pair Energies at LEP / ALEPH Collaboration
Electroweak measurements performed with data taken at the electron-positron collider LEP at CERN from 1995 to 2000 are reported. The combined data set considered in this report corresponds to a total luminosity of about 3~fb$^{-1}$ collected by the four LEP experiments ALEPH, DELPHI, L3 and OPAL, at centre-of-mass energies ranging from $130~GeV$ to $209~GeV$ [...]

Search for Charged Higgs bosons: Combined Results Using LEP data / ALEPH, DELPHI, L3 and OPAL Collaborations
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for pair-produced charged Higgs bosons in the framework of Two Higgs Doublet Models (2HDMs). The data of the four experiments are statistically combined. [...]

Generalized event shape and energy flow studies in $e^+ e^-$ annihilation at $\sqrt{s}$ = 91.2-208.0 GeV / L3 Collaboration
We present results from a study of hadronic event structure in high energy e(+)e(-') interactions using the L3 detector at LEP. A new class of event shape distributions are measured at and above the Z boson pole for light quark (u, d, s, c) flavours. [...]

MIGRATION FROM OPC-DA TO OPC-UA / Farnham, B (CERN) ; Barillere, R (CERN)
The OPC-DA specification of OPC has been a highly successful interoperability standard for process automation since 1996, allowing communications between any compliant components regardless of vendor. CERN has a reliance on OPC-DA Server implementations from various 3rd party vendors which provide a standard interface to their hardware. [...]

Model Oriented Application Generation for Industrial Control Systems / Copy, B (CERN) ; Barillere, R (CERN) ; Blanco Vinuela, E (CERN) ; Fernandez Adiego, B (CERN) ; Nogueira Ferandes, R (CERN) ; Prieto Barreiro, I (CERN)
The CERN Unified Industrial Control Systems framework (UNICOS) is a software generation methodology and a collection of development tools that standardizes the design of industrial control applications [1]. A Software Factory, named the UNICOS Application Builder (UAB) [2], was introduced to ease extensibility and maintenance of the framework, introducing a stable metamodel, a set of platformindependent models and platformspecific configurations against which code generation plugins and configuration generation plugins can be written.

8. The Virtual UNICOS Process Expert: integration of Artificial Intelligence tools in Control Systems
Reference: Poster-2009-135
Keywords:  UNICOS  virtual  artificial intelligence  control system
Created: 2009. -1 p
Creator(s): Vilches Calvo, I; Thomas, G; Barillere, R

UNICOS is a CERN framework to produce control applications. It provides operators with ways to interact with all process items from the most simple (e.g. I/O channels) to the most abstract objects (e.g. a part of the plant). This possibility of fine grain operation is particularly useful to recover from abnormal situations if operators have the required knowledge. The Virtual UNICOS Process Expert project aims at providing operators with means to handle difficult operation cases for which the intervention of process experts is usually requested. The main idea of project is to use the openness of the UNICOS-based applications to integrate tools (e.g. Artificial Intelligence tools) which will act as Process Experts to analyze complex situations, to propose and to execute smooth recovery procedures.

Study of the Solar Anisotropy for Cosmic Ray Primaries of about 200 GeV Energy with the L3+C Muon Detector / L3 Collaboration
Primary cosmic rays experience multiple deflections in the nonuniform galactic and heliospheric magnetic fields which may generate anisotropies. A study of anisotropies in the energy range between 100 and 500 GeV is performed. [...]
