    Evaluation of coronary stents and atherosclerosis employing optical coherence tomography and computational fluid modelling

    © 2017 Dr Muhammad Umair HayatAtherosclerotic coronary artery disease (CAD) is a major health burden worldwide and percutaneous coronary intervention (PCI) is an established treatment for this condition. Both PCI and invasive imaging techniques have evolved tremendously over the past few decades. Limitations of angiography were largely overcome, first by intra-vascular ultrasound, and then, optical coherence tomography (OCT), which is now recognized as the most sensitive and validated tool to examine the vessel lumen, plaque composition and stent-vessel wall interface. This thesis centers on randomized, OCT trials of coronary atherosclerosis and stents. In-vivo, comparative studies of drug eluting stents were conducted to directly observe their mechanical and healing characteristics. Results of these trials subsequently laid foundation for computational fluid dynamics (CFD) experiments and some illuminating observations were made around the effects of stent malapposition on intra coronary flow dynamics. It is the information of this kind that guides scientists to refine stent designs and clinicians, to improve procedural outcomes

    Human reaction time in a mixed reality environment

    Over the last few years applications based on the use of immersive environments, where physical and digital objects coexist and interact, have gained widespread attention. Thanks to the development of new visualization devices, even at low cost, and increasingly effective rendering and processing techniques, these applications are reaching a growing number of users. While the adoption of digital information makes it possible to provide immersive experiences in a number of different applications, there are still many unexplored aspects. In this work, a preliminary step to understand the impact of the scene content on human perception of the virtual 3D elements in a mixed reality has been performed. To this aim, a subjective test was designed and implemented to collect the reaction time of a set of users in a mixed reality application. In this test each user was asked to wear an augmented reality headset and to catch a virtual objects randomly appearing in the subject's field of view. We first estimated the detection accuracy through omitted, anticipated, and completed responses; then we related stimulus location, scene content and estimated accuracy. For this purpose, the area of stimulus presentation was divided into upper, lower, right, left, inner, and outer, to understand in which area responses were omitted and anticipated with respect to the central point of view. Experimental results show that, in addition to the saliency of the real scene, natural body gesture technology and limited field of view influenced human reaction time

    Fertilizing potential and CO2 emissions following the utilization of fresh and composted food-waste anaerobic digestates

    Wet and dry-batch anaerobic digestion, and composting are common technologies in food waste (FW) management, resulting in different outputs. However, the effects of composting on carbon dioxide (CO2) emissions, nitrogen (N) and phosphorus (P) fertilizing capacity in view of closing nutrient cycle are still poorly investigated. In this work, two FW anaerobic digestates from the wet (D1) and dry-batch process (D2), and their respective composts (C1 and C2) were tested in a soil incubation (84 days at 25 °C) to assess CO2 emissions in comparison with a mixed (animal slurry/energy crop) digestate (BD) and a reference municipal solid waste compost (MSWC). The same products were also tested for the relative P efficiency (RPE) in soil, in comparison with a chemical-P source (30 mg P kg−1). Lastly, the apparent recovery fraction of N (N-ARF) from the five organic products was determined in a pot test with ryegrass (84 days; 300 kg available N ha−1), compared to a chemical fertilizer (NPK). Composting strongly reduced net-CO2 emissions compared to the two digestates (625 vs. 2850 mg CO2 kg−1 soil). Oppositely, composting very modestly influenced RPE that ranged around 100–90% in D1 and C1, and ≈30% in D2 and C2. Moreover, composting did not significantly reduce N-ARF that ranked in descending order as follows: NPK (77.5%) &gt; D1 = BD (17.7%) ≥ C1 (14.7%) &gt; MSWC (3.6%) &gt; D2 (1.2%) &gt; C2 (−3.1%). Composting was shown a reliable strategy for FW digestate management, as it reduces potential CO2 emission without affecting these products' N- and P-fertilizing capacity
