Therefore, it is essential to implement efficient techniques to enhance the efficiency of fuel cells.
Today, it is essential to implement new technologies and teaching methods that are flexible and encourage students to acquire the necessary professional skills.
To address these challenges, it is essential to implement actions with a balance between bottom-up and top-down approaches (Zia and Wagner 2015).
To minimize the cost it is essential to implement appropriate embedded hardware and software (real-time operating system and communication protocol) meeting the real-time IVC application.
Thus, although simulation and theoretical analysis are helpful in a preliminary evaluation of new protocols and algorithms, it is essential to implement, test, and evaluate them in a testbed (prototype) network for performance assessing under real-world conditions.
For this reason, it is essential to implement actions focussed on the system (namely the equipment) and in the examination room (layout) so that working conditions can be improved and radiographers' health risks reduced [1, 4, 5].
Due to the important nature of the information contained in documentation and to the complexity and the number of parties involved in a well test operation, it is essential to implement document controls from the start of planning.
The mechanical property of elastomeric foams is highly nonlinear and it is essential to implement mathematical constitutive models capable of accurate representation of the stress strain responses of foams.
To make the simulation model as close to the reality as possible it was essential to implement the correct times for transit of the trains between stations, as well as the correct time that a train would spend waiting at a station.
In order to evaluate and design hydraulic stimulation in these reservoirs, it is essential to implement a holistic approach in which conducting a secondary fracture treatment after a primary production period from an initial hydraulic fracture is considered as an option.
