Propagation Of Uncertainties

In this paper, we addressed the qualitative consequences on uncertainty for the execution of a inclining test of a Semi-submergible platform with mooring system and risers at production site and compared the results to the ones taken from typical inclining test procedures at sheltered waters, as defined by ASTM F1321. To accomplish that, we applied Uncertainty Analysis according to ISO procedures, by evaluating propagation of uncertainties from the measurements until the final calculations. We discussed the use of measurement devices for the variables of concern and performed some numerical simulations to address the mooring system restoring effects and its implications on uncertainty analysis. We used data from two semi-subs with different displacements and found small influence on final uncertainty from the addition of mooring system and risers. At end, we discussed how new technologies on data acquisition and filtering of signals can become an important tool to help in the safety of the offshore floating production units, by facilitating the verification of the updated center of gravity of them after important interventions.

Based on the CEAB investigation attribute requirements, the Laval University Mechanical Engineering department has entirely modified its philosophy regarding the lab course. This course is now based on teamwork projects that take place throughout the semester. Different experimental setups are available to accommodate up to 20 teams of three students on a 24h/7d schedule. This paper offers some examples of lab benches and problems designed for this approach. To begin, student teams must describe the apparatus on which they will conduct an investigation and propose a problem they intend to study. Next, teams present theoretical background and a literature review. They determine the physical quantities to be measured and describe the measuring instruments to be used. Then, they plan and prepare a test campaign, including development of their own data acquisition, control and processing programs using LabVIEW. Finally, teams conduct their test campaign, analyze the results (including detailed uncertainty analysis) and report on their findings.

Cardiac Mdct

Over the last decade, cardiac computed tomography (CT) technology has experienced revolutionary changes and gained broad clinical acceptance in the work-up of patients suffering from coronary artery disease (CAD). Since cardiac multidetector-row CT (MDCT) was introduced in 1998, acquisition time, number of detector rows and spatial and temporal resolution have improved tremendously. Current developments in cardiac CT are focusing on low-dose cardiac scanning at ultra-high temporal resolution. Technically, there are two major approaches to achieving these goals: rapid data acquisition using dual-source CT scanners with high temporal resolution or volumetric data acquisition with 256/320-slice CT scanners. While each approach has specific advantages and disadvantages, both technologies foster the extension of cardiac MDCT beyond morphological imaging towards the functional assessment of CAD. This article examines current trends in the development of cardiac MDCT.
