we aimed to investigate the correlation of tonsillectomy with palatine tonsil size and to compare the differences of tonsil size and the need for surgery in children and adults. also we can predict the outcome of tonsillectomy. we measured tonsil sizes in (height and width) in 150 children and 35 adults with hypertrophy of palatine tonsils and we measured the mass of tonsils and then the data a...

Data quality issues have become increasingly critical for information systems applications in organizations of all sizes. This paper presents results from a large-scale Australian survey of Australian CPA members. The research investigates major stakeholders’ opinions on the importance of critical success factors affecting data quality and the actual performance on each of those factors. The re...

Israel has known a very high inflation rate and two currency changes in the past five years. Coin size estimation by 97 subjects reveals a general tendency to underestimate sizes. The specific pattern of results suggests that coin size estimation is influenced by the subject’s attitude towards the coin in question, that inflation and actual value of the coin are not the only determinants of tha...

The performance of a Hamming Distance Classiier based on static memory cells and an analog winner-takes-all circuit depends on device matching in the various parts of the circuit. This dependence has been analyzed, leading to design criteria for choosing the device sizes and chip structure. The theoretical performance of a CMOS chip designed to operate in the subthreshold region has been compar...

We use a ballistic model to simulate the particle number densities in plumes on Io as a function of eruption rates and particle size distributions. Comparison of the simulated apparent brightness variations within plumes with the properties of actual plumes allows constraints to be put on the particle sizes present and the eruption rates. We find evidence for lower eruption rates, by a factor o...
