One of the core concepts of contemporary control theory is the idea that a dynamical system can be controlled. Several abstract settings have been developed to describe the distributed control systems in a domain in which the control is acted through the
Chi-square tests confirmed that the perfusion pattern of the contrast agent plays an important role in the differential diagnosis of OETs. Compared with those in the benign group, the BOTs were not significantly different in terms of perfusion phase and enhancement intensity, but the regression ...
Chaniotakis and Pel, 2015, James, 2018). From the Model [1]’s results (Table 9) emerge that €9.25/hour is the average Value of Travel Time Savings (VTTS) for the case study considered. This value refers to the average passenger and is consistent with those proposed in many ...
Complex numbers are those numbers which express in the form of x+yi, where x and y are real numbers and ‘i’ is an imaginary number known as iota. For example 4+2i, 6-4i, etc. Now the absolute value of the complex number is the positive square root of the sum of the squares ...
