Task Sequence

The objective when planning the time dimension is to determine the shortest time necessary to complete the project. Begin with the work breakdown stmcture and determine the time required to complete each task. Next, determine in what sequence tasks must be completed, and which ones may be under way at the same time. From this analysis, you will have determined the three most significant time elements ... 

Marijuana has been shown to impair learning in the repeated acquisition and performance of response sequences tasks. Increased errors in the acquisition phase were reported after smoked marijuana (2.0 and 3.5% THC)244 and oral THC (10 and 20 mg) 247 However, other studies40,52 have found no effect of smoked marijuana on this test, and one study251 reported that oral THC (20 mg, q.i.d.) increased the number of completed trials. Block et al.233 reported that one marijuana cigarette (2.6% THC) impaired paired-associative learning. 

A) An example of a five-item monotonic size sequence and the touch sequence required on a particular trial. While the sequential requirement remains the same throughout the task, the spatial layout changes randomly from trial to trial. (B) An example of a color sequencing task, trained under the same conditions as (A).

Our main purpose is to understand which column sequences can be used in order to get the necessary products. This task is called the task of sequencing (synthesis). The sequencing task is being solved in consecutive order beginning with the first distillation column, where initialn-component mixture comes to. For each column, it is necessary to determine feasible splits.
