We investigate the dynamics of membranes that are held by freely-rotating rigid tethers in fluid flows. The tethered boundary condition allows periodic and chaotic oscillatory motions for certain parameter values. characterize oscillations terms deflection amplitudes, dominant periods, numbers local extrema along across space membrane mass density, stretching modulus, pretension, tether length....

Design of foundations in earthquake prone areas needs special considerations. Shallow foundations may experience a reduction in bearing capacity and increase in settlement and tilt due to seismic loading. The reduction in bearing capacity depends on the nature and type of soil and ground acceleration parameters. In the case of piles, the soil-pile behavior under earthquake loading is generally ...

• The fifth objective of the AASHO Road Test was as follows: "To develop instrumentation, test procedures, data, graphs and formulas which will reflect the capabilities of the various test sections; and which will be helpful in future highway design in the evaluation of the loadcarrying capabilities of existing highways and determining the most promising areas of further highway research." It w...

or intact muscle. End-systolic pressure-volume relations of frog hearts have been found to be load dependent, whereas those of the mammal are relatively load independent. On the other hand, myocardial relaxation as studied at the muscle level is load independent in the frog but markedly load dependent in the mammal. Interpretation of these studies is complicated because of the unknown contribut...

Steam Turbines are devices used to convert thermal energy of steam into mechanical energy, which may be used to produce Electrical Energy. Steam turbine generator units are being used extensively all over the world for generation of electric power and for co-generation of steam and power. Contact pressure and pretension in bolts-analysis has been made easier in recent years due to the availabil...

In prospective memory tasks different kinds of load can occur. Adding a prospective memory task can impose a load on ongoing task performance. Adding ongoing task load (OTL) can affect prospective memory performance. The existence of multiple target events increases prospective load (PL) and adding complexity to the to-be-remembered action increases retrospective load (RL). In two experiments, ...

  Background : Epidemiological studies showed that low back pain after load-carrying and holding is the most common disorder in industrialized countries and cause of dysfunction and economic problems. Variable dynamic loads impose varying moments about the intervertebral joints and cause a threat to balance. The aim of the present study was to compare the postural stability while holding dynami...

One of the main factors affecting performance telescopic booms is loss local stability shelves and section walls. The sections occurs due to development plastic deformations in some most loaded or as a result stable equilibrium even at stage elastic deformation. In this case, maximum stresses boom are formed location supporting elements, where summation from external loads forces acting side el...

Artificial Neural Networks are information processing systems. Over the past several years, these algorithms have received much attention for their applications in pattern completing, pattern matching and classification and also for their use as a tool in various areas of problem solving. In this work, an Artificial Neural Network model is presented for predicting the tensile properties of co...
