the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
evidence provided from studies in iran points to a possible bias in application of the standard epi cluster sampling procedure, when carried out in populations with highly variant birth rates, tends to over-represent the low birth rate, i.e. higher socio-economic, strata, and if the entity under study shows significant socio-economic gradient, then the estimates arrived at by this method might ...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
Motor induksi 3-fasa akan beroperasi pada keadaan ideal ketika disuplai dengan sumber tegangan sinusoidal yang memiliki per-fasa frekuensi sama, magnitudo sama serta saling berbeda fasa 120°. Namun dalam riilnya motor seringkali kondisi tak ideal, sebagai akibat ketidakseimbangan suplai daya listrik dapat mempengaruhi unjuk kerjanya. Dalam kegiatan penelitian ini dilakukan pengujian dua yaitu d...

A novel method is presented for predicting the common secondary structures and alignment of two homologous RNA sequences by sampling the 'structural alignment' space, i.e. the joint space of their alignments and common secondary structures. The structural alignment space is sampled according to a pseudo-Boltzmann distribution based on a pseudo-free energy change that combines base pairing proba...
