  • Decomposing Mechanism of SF6 under Positive DC Partial

    Thus, SF6 decomposition experiments under positive DC PD are performed to reflect the influence of H2O on SF6 decomposition components. Results show that the total discharge quantity and the discharge repetition rate averaged for 1 s decrease slightly when the H2O content increases from 0 to 970 ppmv and then increase when the H2O content increases from 970 to 5120 ppmv.

  • Project Scope Management: What It Is and Why It’s Important

    An Overview of Project Scope ManagementWhat Is Scope in Project ManagementImportance of Scope Project ManagementProcesses of Project Scope ManagementTo make it simpler to understand, let us compare delivering a project with constructing a building. A fence is raised around the site before the construction happens. It is done to define the boundaries of the construction so that people involved in the construction part know where to stop. This part is called scoping. Project scope managementmainly revolves around controlling what is and what is not included in the project. It plays a crucial role in helping project managers, coordinators, supervisors to focus on what’s really important for the project and allocate the right amount of work to team members that could actually help the project to be successfully completed.
