Modelling the installation of offshore wind farms: Defining the installation of offshore wind submarine power cables using a discrete event simulation based logistics model
No full textA gap in the understanding of offshore wind submarine power cables is responsible for 70-80 % of failures in recent times. The failures originate from the phases of design, manufacturing, installation and operations. Joint industry collaborations such as the Cable Lifetime Monitoring project that form the background for this thesis, are aimed at developing knowledge of these failures. The origination of failures from the installation phase of power cables is of particular interest. In order to do so, a model has to be developed first to understand the processes involved in an installation plan, as well as their time and resource costs. Logistics and planning tools such as ECN Install are utilized for this purpose and provide the medium for capturing the installation processes for submarine power cables. This thesis aims to describe the installation of power cables using a discrete event simulation based logistics model such as ECN Install. The first part of the thesis focuses on a literature review to categorize all aspects of power cable installation. Here the stages of a project, the installation processes, assets, methods and influencing weather parameters are identified. From this literature review it is found that the most important stage of a power cable installation project is the Marine Installation Program. The decisions leading to the development of a Marine Installation plan are mapped for modelling. The second part of the thesis deals with applying the knowledge acquired into the logistics model. Here, the model assumptions are set in order to create an accurate depiction of the installation processes. The third part of the thesis investigates the influence of input uncertainties on the model as a means to understand the relationship between the different aspects of a power cable installation project to its Marine Installation Program. A sensitivity study is performed to quantify the impact of different uncertainties on a Marine Installation Program. The final part of the thesis has theanalysis of a historical case study. Here the Marine Installation Program of the Gemini export cable is constructed.Electrical Engineering | Sustainable Energy Technolog
Quantitative Analysis of Grinding Wheel Loading Using Image Processing
No full textAbstractGrinding is an abrasive machining process which can produce very fine surface finishes. The removed chips from the workpiece which get welded to the porosities between the abrasive grains can adversely affect the final surface finish of the machined component. Quantitative analysis of wheel loading can provide information about the cutting conditions of the wheel. With the development in the field of machine vision and image processing, this study focuses on developing a system for the quantitative assessment of wheel loading using image capturing and image processing. Images of the grinding wheel were acquired using microscope with a magnification of 20x. Image segmentation by global thresholding technique was utilized for segmenting the loaded portions from the rest of the wheel. Experimental results presented show the feasibility of the proposed system in the quantitative assessment of grinding wheel loading
THE PRIMAL FEAR: THE LANGUAGE OF THE FUTURE IN THE HUNGER GAMES
No full textThe Hunger Games series was banned to begin with before even it became a cult classic because of its anti-family concerns, the rebellion and the attitude of challenging the governmental authority. The system of futuristic governance is a warning to the readers, especially the teens of tomorrow as to how their lives would be in future if they continue to remain complacent about the ways of the authorities who rule them over. There is crime, retribution and rebellion each of which has its causes, consequences and repercussions. The paper aims to look at the struggle for food which Katniss and Dale confront to take care of their families written in the language of the future. The words which the author has coined for the future and the shades of meaning that they give are also highlighted
Analysis of taxi dataset to categorize city rankings
Get PDFThe city administration values the district attraction rating since it can aid in extracting the desirability of the location and hence support the officials in making smart city development decisions. Traditional urban planning tactics mostly rely on Gross Domestic Product, rate of employment, number of people per unit area, and district statistics gleaned through surveys and questionnaires, among other factors. As a point of reference, such knowledge becomes less and less helpful over time. The volume of urban data is growing at an exponential rate. Furthermore, these tactics suffer from a fatal flaw: they are unsuccessful. Independent representations of a district's appeal, as well as inter-district interactions, are not taken into account. It is now feasible to use urban data efficiently for urban planning thanks to advances in urban computing. To that end, this paper proposes PageRank, a district attractiveness rating algorithm based on taxi big data, which is the first to do so. A working software is constructed for visualization motives. To begin, the total area is split into numerous parts using the k-means algorithm
