This simulation study examined the performance of the curve-of-factors model (COFM) when autocorrelation and growth processes were present in the first-level factor structure. In addition to the standard curve-of factors growth model, two new models were examined: one COFM that included a first-order autoregressive autocorrelation parameter, and a second model that included first-order autoregr...

As fretting fatigue cracks are initiated at an early stage of life, the fretting fracture process is dominated by the stable growth of cracks. Hence the measurement of crack length is very important. This paper demonstrates the suitability of the DC potential drop technique for the measurement of fretting cracks. A calibration has been established for monitoring crack growth in BS L65 copper al...

Labeo rohita is a member of the Indian major carp species and originally an inhabitant of the Ganga river network in India. It is among the top ten aquaculture species of the world. Since there is a lack of information on the growth pattern of the wild populations of this species, this study aimed at evaluating the pattern of age and growth, to support the development of effective management pl...

Several methods have been studied to predict the timing and magnitude of the pubertal growth spurt in the individual child. Different maturity indicators can be used like skeletal age in different areas, the Risser sign, status of the triradiate cartilage, Tanner stage of sexual maturation, age of the thelarche and menarche, and several body length dimensions. Furthermore, the trend in total bo...
