View description>>
Concrete properties prediced by Australian, European and American codes of practice are compared with measured values. Their effects on the long-term deflections of two simply supported beams are investigated. The methods employed to calculate the deflections include commonly used simplified design methods, and finite analyses incorporating material data obtained both from code predictions and from tests. The deflections predicted by the various methods are compared with test results from the two beams.

Long-term tests on prototype sized, closed rectangular reinforced concrete frames are described and the principal results are presented. A second order non-linear frame analysis program is also presented. The reliability of the program is assessed by comparing predicted values with results obtained from the tests on the closed rectangular frames, and also from tests conducted elsewhere on fixed base portal frames. The results of material tests, which define the short-term and long-term material characteristics are given.

AbstractLevinson's algorithm is one of the fast algorithms for estimating the parameters of an auto‐regressive model. Since this algorithm is recursive with respect to the order of a model, it is an effective method to obtain models of various orders when the true order is unknown. This paper proposes a fast algorithm to estimate the parameters of an autoregressive and a movingaverage model. the parameter estimation can be accomplished using a criterion based on the least square method. the problem of estimating autoregressive and moving‐average parameters from the criterion is reduced to that of solving a 2 × 2 block Toeplitz matrix. This method is an algorithm to solve this block Toeplitz matrix rapidly and it does not require the calculation of the inverse matrix. Also, it is recursive with respect to the order; the orders of an autoregressive model and a moving‐average model can be changed independently of each other. This method is an expansion of Levinson's algorithm and this paper shows the relationship between this method and Levinson's algorithm. Furthermore, properties of this method are discussed and as an example of its application, an experiment of model reduction is performed.

In deep bed filtration, the removal of particles in the suspension is complex and depends on numerous filtration parameters. The mathematical models describing deep bed filtration involve several filtration coefficients which are characteristic of the particular suspension to be filtered and the type of filter media used. If these coefficients are evaluated from a limited number of filter experiments, filtration performance can be simulated for any operating conditions which would be helpful in designing the filter in a rational manner. This paper presents the simulation of dual media and radial filters from a limited number of conventional (vertical down flow) filter experiments. The simulated and experimental results are found to be comparable which indicates the usefulness of simulation in deep bed filtration.

View description>>
Filters with mobile-bed arrangement eliminate the problem of back washing and use the entire filter bed in efficient filtration action. The optimum values of operational parameters of mobile-bed filter (sand-recycling rate, sludge-withdrawal rate, filter media specifications, filtration rate) can be evaluated from laboratory-scale experiments with the particular water to be treated. These values can be used to design a plant-scale mobile-bed filter in a rational manner.
