“…The calculation result of internal entropy is the sum of organizational entropy and team construction and management entropy. Where 1 H is the organization entropy and 2 H is the team building and management entropy [14]. The calculation results of tissue entropy are as follows: The five randomly selected management teams are teaching building A and B, two teams, teacher management team and student management team.…”

In order to explore the analysis of educational management strategies in Colleges and universities, a method based on entropy and dissipative structure theory is proposed. Firstly, we determine the connection length B, which refers to the shortest path between two elements in the structure diagram. The length of direct connection is 1, and the length of each transfer is added by 1. Secondly, calculate the total number of microscopic states of the system, A 1, A 1 = ∑ ∑ Lab {A_1} = \sum {\sum {Lab} } . Third, calculate the probability value of the realization of the micro state of each connection: P ( a , b ) = L ab A a P\left( {a,b} \right) = {{L _{ab}} \over {{A_a}}} . Finally, the entropy of organizational structure between any two elements of the system at the same level vertically and horizontally is calculated: H 1(ab) = −Pa (ab) ln Pa (ab). The experimental results show that student satisfaction is considered to be an important dimension of management team performance evaluation. Through the survey of student satisfaction, it is found that the student satisfaction rate of two teams is 100%, the student satisfaction rate of two teams is 99%, and the satisfaction rate of one team is 98.5%, which shows that the management team has good performance. It is proved that the theory of entropy and dissipative structure can effectively improve the educational management strategy of colleges and universities.

“…Finally, in some systems, video cameras allow detecting movements and speeds through image analysis. These devices have the advantage of being able to detect several users simultaneously, calculating speeds and sense of movement, see for instance [25]- [27]. In addition to those concerning personal protection laws, the cameras' problem would require the support of infrared bulbs.…”

Intelligent control of public lighting is nowadays one of the most challenging issues in smart city deployment. Lighting optimization entails a compromise between comfort, safety, and power consumption, affecting both vehicles and pedestrians. Smart solutions must estimate their characteristics to trade-off users' needs and energy requirements. This paper proposes an intelligent street lighting control system and the Receiver Operating Characteristic (ROC) curve method to evaluate the best number of street lamps to achieve a balance between public road user comfort and system power consumption. The control system is based on the detection of users, mainly pedestrians, using presence sensors. From the detection of a pedestrian by two or more consecutive street lamps it is possible to determine their speed. Knowing the pedestrian speed, allows the system to anticipate and adjust the light intensity of the remaining street lamps, and provide a comfortable view of the street. Using the ROC curve, we evaluate the control algorithm in terms of the number of previous street lamps used. We have tested the system and the method in a model of pedestrians walking down a street. The obtained results show that ROC analysis used to control street lighting allows measuring the whole control system's efficiency by providing a concrete number of previous street lamps.
