Quality Management during Oil and Gas Project Phases
Published in Abdul Razzak Rumane, Quality Management in Oil and Gas Projects, 2021
Owner/consultant inspects the works and inform contractor of unfulfilled contract requirements. A punch list (snag list) is prepared by the consultant listing all the items still requiring completion or correction. The list is handed over to the contractor for rework/correction of the works mentioned in the punch list. Contractor resubmit inspection request after completing or correcting previously notified works. A final snag list is prepared if there are still some items which need corrective action/completion by the contractor; such remaining works are to be completed within the agreed period to the satisfaction of the owner/consultant. Table 8.41 is sample form for preparation of punch list.

Construction close-out includes not only completion of the physical construction of the project, but also submission of all required documentation to the project owner, and financial close-out. The PM and superintendent must pay close attention to detail and motivate the project team to close-out the project expeditiously to minimize jobsite overhead costs. Physical close-out, including the punch list, and close-out documentation are discussed in Section E, Chapters 17 and 18. Post-project analysis, if conducted, involves reviewing all aspects of the project to identify lessons that can be applied to future projects. Issues such as estimated cost versus actual cost, planned schedule versus actual schedule, quality control, supplier and subcontractor performance, construction equipment choices, effectiveness of communications systems, and work force productivity should be analyzed. Contractors who conduct post-project analyses learn from their experiences and continually improve their procedures and techniques. The lessons-learned analysis may be included as part of the PM’s and superintendent’s close-out phase.

“Mechanical completion” is a key milestone of a project at the end of construction and is contractually documented with a certificate signed by the owner. It declares completeness and robustness of the plant (or section of it for which the mechanical completion certificate is drawn) in line with the project drawings, specifications, applicable codes, and the contract.
On the Completion of Fuzzy Normed Linear Spaces in the Sense of Bag and Samanta
Published in Fuzzy Information and Engineering, 2021
The study of completion of fuzzy metric space and fuzzy normed linear space constitutes a natural and interesting open question in the analysis of such spaces. The first effort is due to Kaleva [16] in the frame of fuzzy metric space introduced by Kaleva. From then on, many authors devoted to study the completion of fuzzy metric spaces or fuzzy normed linear spaces in the sense of Kaleva type or Felbin type, and several important results are discussed ([17–20]). The study of completion on the fuzzy metric space introduced by Karmosil and Michalek is originally Gregori and Romaguera [21], an ordinary topology is considered in their study. They show that for each fuzzy metric space there is an (up to uniform isomorphism) unique complete fuzzy metric space that contains a dense subspace uniformly isomorphic to it. The original research of completion on the fuzzy normed linear spaces was Felbin' s work in [19] with help of usual classical topology. As above claimed, Saheli [12] introduced a new I-topology on fuzzy normed linear space in the sense of Bag and Samanta recently. From the properties discussed by the author, we may consider this new I-topology is more suitable for the further study in fuzzy normed linear space.

The average module completion rate was 90.40% for PWDs and 90.48% for NODs. In comparison with the study performed by Cooper et al. (2016) where the module completion rate was 69.5% for PWDs and 75.3% for NODs, in our MOOC the vast majority of learners complete a module as long as they participate in it. From the 32 modules in our MOOC, there are 15 modules with an OR value inferior to 1 (52%) and two with an OR value equal to 0 (i.e., all PWDs completed the module). As no module exhibits an OR value above 3 (max OR = 2.43), we can conclude that accessibility is not a dominant factor in determining the completion rates of PWDs (Cooper et al., 2016).
Adaptive diffusion strategies with Markov jump over networks
Published in Systems Science & Control Engineering, 2020
Next let us consider the optimization of the following global cost function Our strategy to optimize in a distributed manner is based on two steps, following the developments in Chen and Sayed (2012b, 2013). First, using a completion-of-squares argument (or, equivalently, a second-order Taylor series expansion), we approximate the global cost function (18) by an alternative local cost that is amenable to distributed optimization. Then, each node will optimize the alternative cost via a steepest-descent method.
