Several research groups in the world have measured ground motion to estimate its influence on the parameters of particles in accelerators (e.g. luminosity, emittance). The chosen topics of the problem of influence of ground motion on vibrations of particle accelerators are discussed in this paper. The main purpose of this paper is to present an overview of the methods and techniques that can be utilized for estimating the impact of vibrations on the stability of the beam circulating inside a synchrotron(or moving within an accelerator in general). Specifically the paper presents the detailed results from the measurements performed at SOLARIS (National Synchrotron Radiation Centre, Cracow) and CERN (European Centre for Nuclear Research, Geneva).

Many of the manufacturing industries use sheet metal for optimizing the weight of the products. Forming process has been successively increasing during the past few decades. Indexing mechanisms have been used in milling, weaving, packing, etc. for continuous production purpose. Shearing of sheet metals has been widely used for optimizing the weight of the components and products. Crank slotter mechanism was widely used in the mechanisms for intermittent operations. This has been replaced by Geneva mechanism. The paper aims at deriving the mathematical relations for slotted Geneva wheel using curve theory. The kinematic characteristics are derived using the DH notations Finite element analysis has been done on the designed Geneva wheel with pin. It is analysed for the contact stresses when the drive crank pin slides along the slots of the wheel to operate the mechanism. [ABSTRACT FROM AUTHOR]

The purpose of presented work is the analysis of impacts of Working from Home on Teachers using DEMATEL methodology. Methodology – The DEMATEL approach was originally proposed by the Batter Memorial Association in Geneva. This approach is used in many fields to investigate the relationships between specific metrics. This approach consists of several steps that lead to final value. Findings – Total eight critical factor impacting of Working from Home on Teachers have been compared and ranked. 'Ineptitude in practical based subject' has proved to be the most critical factor impacting of Working from Home on Teachers. Research Implications – A decision- making trial and evaluation laboratory (DEMATEL) approach was used to identify and analyze the impacts of Working from Home on Teachers. Value – 'Ineptitude in practical based subject' and 'Reduced stress level' have been found as the most and the least critical factor impacting of Working from Home on Teachers respectively. The resultant will be instrumental for the strategy creators for planning effective tactics to tackle with factors affecting teachers working from home. [ABSTRACT FROM AUTHOR]

The Liquid Argon Calorimeter (LAr) is a subsystem in the ATLAS experiment which is being assembled at the Large Hadron Collider (LHC) at CERN. The readout electronics system for the LAr is discussed here. The front-end of the readout will work in radiation environment. This special requirement has led to the development of a large number of rad-hard ASICs. The back-end of the readout employs DSPs to process data to reduce transmission bandwidth. The installation and commissioning of this readout is also discussed here. © 2006 American Institute of Physics [ABSTRACT FROM AUTHOR]
