Effect of the Switch Time Interval

Extended-release capsules - In children with ADHD who are at least 6 years of age and are starting treatment for the first time or switching from another medication, start with 10 mg once daily in the morning daily dosage may be raised in increments of 10 mg at weekly intervals. Administer amphetamines at the lowest effective dosage. The maximum recommended dose is 30 mg/day doses larger than 30 mg/day of extended-release amphetamine mixture capsules have not been studied. 

Although all physical processes are, of course, of limited duration there are many situations in which this limitation is not of practical interest. When studying the noise in an electronic device one normally is not interested in effects connected with the switching on and off. A description in which the duration does not enter is then simpler and more appropriate. One is thus led to examining sets of dots whose density does not tend to zero for t - + oo. Such sets cannot be described in terms of the Qs, because the normalization condition (1.3) requires Qs to vanish at infinity. It is true that this shortcoming can be overcome by introducing a fictitious long time interval T, but that burdens the equations with an irrelevant quantity. The description in terms of the / , however, carries over without additional artifice.
