Finally, the capacity of this spreadsheet-based tool is demonstrated by means of a two-stage case study, which includes assessing the importance of a number of exogenous policy risks, as well as evaluating different short-term policy instruments against these risks.
The Stage 1 case study develops fundamental principles of chemical engineering (mass and energy balances, reaction kinetics, heat transfer, sustainability) whilst Stage 2 case studies concentrate on separation processes and the reactor engineering aspect at the same time requiring the application of the knowledge of statistics and design of experiments, respectively.
The second stage, the case study, entailed the setting up of a small-scale (10 m3) household biodigester in the Muldersdrift community in Gauteng, South Africa.
Student evaluation via questionnaires, focus groups and comments from individual reflective reports, submitted as part of the evaluation of the Stage 1 case study activity, demonstrate the impact of these case studies on student learning and their behaviour.
IBM performance in the first stage of the case study has been compared with the performance of the second stage by comparing the registration success scores.
In summary, the research hypothesis that the approach of capturing photos in usual photography does not lead to appropriate 3D point cloud models is supported by the low registration success score (recall) in the first stage of the case study in contrast to the high score in the second stage of the case study.
To validate SPP, the second stage of the case study is conducted and the images are captured based on SPP. The IBM in the first stage of the case study results in sparse models, which hardly show the geometry of construction scenes.
Figure 8 shows this photography error that occurred in the first stage of the case study.
Figure 6 Sixteen reconstructed sparse models obtained from the first stage of the case study (four of them are shown).
Routine CT examination proved very useful in finding the pleural metastatic lesion at the localized stage in this case study.
SPP is proposed based on the findings of the first stage of the case study and on the findings of previous studies in the field of IBM.
