Batch processes are commonly characterized by uneven trajectories due to the existence of batch-to-batch variations. The batch end-product quality is usually measured at the end of these uneven trajectories. It is necessary to align the time differences for both the measured trajectories and the batch end-product quality in order to implement statistical process monitoring and control schemes. ...

Suppose you look at today's stock prices and bet on the value of the first digit. One could guess that a fair bet should correspond to the frequency of 1/9 = 11.11% for each digit from 1 to 9. This is by no means the case because one can easily observe a strong prevalence of the small values over the large ones. The first three integers 1,2 and 3 alone have globally a frequency of 60% while the...

A recently-published paper by Wickremasinghe et al assesses the scalability of pilot projects in three countries using the aid effectiveness agenda as an analytical framework. The authors report uneven progress and recommend applying aid effectiveness principles to improve the scalability of projects. This commentary focuses on one key principle of aid effectiveness – country ownership; it desc...

A method for appraising the distribution of diffusing capacity of the lungs (D(L)) in relationship to pulmonary capillary blood flow ([unk]Q(C)) in normal human subjects was derived from measurements of oxygen diffusing capacity (D(LO2)) and carbon monoxide diffusing capacity (D(LCO)) performed during breath holding. This method utilizes the fact that the observed D(LO2) is considerably reduced...

The paper extends the notion of linear programming boosting to handle uneven datasets. Extensive experiments with text classification problem compare the performance of a number of different boosting strategies, concentrating on the problems posed by uneven datasets.
