Visualizing the behaviour of reinforced concrete beam structure under various types of loadings

  This paper describes an approach to visualizing the detection of failure in Reinforced Concrete Beam Structure under various types of loadings. Several Reinforced Concrete Design (RCD) tools have been developed to support RCD, but there is little evidence that these solutions address the needs of the users. We studied RCD analysts’ daily activities in order to understand their routine work practices and...

Relative efficiency of non parametric error rate estimators in multi-group linear discriminant analysis

  A Monte Carlo study was achieved to assess the relative efficiency of ten non parametric error rate estimators in 2, 3 and 5-group linear discriminant analysis. The simulation design took into account the number ρ of variables (4, 6, 10, 18) together wit the size sample n so that: n/ρ = 1.5, 2.5 and 5. Three values of the overlap, e of the populations were...

A catastrophic-cum-restorative queuing model with correlated input for the cell traffic generated by new broadband services

  A Catastrophic-cum-Restorative Queuing Model has been developed for the cell traffic generated by New Broadband services. Transient analysis of the queuing model has been carried out. Some particular cases of the model have been derived and discussed.   Key words:  Catastrophes, correlation, broadband services, restoration.
