The Advantage of Evidential Attributes in Social Networks
Nowadays, there are many approaches designed for the task of detecting
communities in social networks. Among them, some methods only consider the
topological graph structure, while others take use of both the graph structure
and the node attributes. In real-world networks, there are many uncertain and
noisy attributes in the graph. In this paper, we will present how we detect
communities in graphs with uncertain attributes in the first step. The
numerical, probabilistic as well as evidential attributes are generated
according to the graph structure. In the second step, some noise will be added
to the attributes. We perform experiments on graphs with different types of
attributes and compare the detection results in terms of the Normalized Mutual
Information (NMI) values. The experimental results show that the clustering
with evidential attributes gives better results comparing to those with
probabilistic and numerical attributes. This illustrates the advantages of
evidential attributes.Comment: 20th International Conference on Information Fusion, Jul 2017, Xi'an,

Assessing Scotland's Progress on the Environmental Agenda
For good reasons the environment has a high political profile in Scotland. This report is concerned with three important components of the environmental agenda and the way in which they are being taken forward by the responsible authorities in Scotland. The delivery of environmental outcomes on agricultural land by means of a range of current policies, including agri-environment schemes, cross-compliance conditions on direct payments to farmers and implementation of the EU Water Framework Directive.The selection and management of a new network of Marine Protected Areas.Policy measures designed to reduce greenhouse gas emissions and to mitigate climate change.Each of these topics is addressed individually in three separate chapters, aiming to identify some of the leading questions and the policy responses that have been adopted. The progress that is being made in meeting the objectives and aspirations set out in legislation and other key policy documents is then considered. Some of the objectives under review are determined entirely by the Government and by more local authorities in Scotland. Others arise primarily from obligations under EU legislation
Philosophy as a religious experience in Plato
Plato is a philosophical theologian in whom philosophy and theology are
synonymous, and the way of philosophy a religious endeavour. However, contemporary
scholarship overlooks the importance of the religious dimension of Plato's philosophy,
and in particular, neglects an examination of the theological ideas that are involved in this
understanding. In answer to this, the thesis argues that, in Plato, philosophy is a religious
human experience, that it is within such a perspective that Plato's philosophical theology
can be properly understood, and that such a perspective provides both theological and
philosophical insights. The thesis offers a unique contribution to scholarship in that it
examines the issues of Plato's philosophical theology from the perspective of Plato's
philosophy as a religious experience. Secondly, it relates the question of the religious
nature of Plato's philosophy to the issue of humanity by seeing Plato's philosophy as a
means of human transformation and as a religious way of life and existence. And thirdly,
by interacting with recent scholarly interpretation and commentary, seeks ways in which
such a perspective provides insights for contemporary theological and philosophical
thought. To examine these issues, the thesis employs two overarching themes:
philosophy as a religious experience as involved directly with the question of the human
situation and life, and the human experience of the divine in Plato. Chapters One and
Two consider, respectively, Plato's philosophy as a way of salvation and transformation
in the individual and society, and the idea of the philosophical life. Chapters Three
through Five examine the religious experience of the Forms as divine reality and the
meaning to human existence, the idea of the personal relationship between the
philosopher and the divine, and the philosophical experience of divine inexpressibility.
Lastly, in the Conclusion, I seek to apply the idea of Plato's philosophy as a religious
experience to a contemporary context by raising several ofthe important issues that are
involved when Plato's philosophy is realised as a religious way of life today. The thesis
concludes that what is manifested in Plato is a deep interrelation between philosophical
and religious thought which gives rise to a vibrant and insightful philosophical theology
of Plato's philosophy as a religious human experience
A Comparison of Fuel Efficiencies Between DC-9-30 and B-737NG Aircraft for Delta Airlines at Atlanta Hartsfield Airport
Improved fuel efficiency is one of aviation\u27s top priorities, as it impacts the economy and the National Airspace System\u27s environment. This descriptive study used data generated by the Total Airspace and Airport Modeler (TAAM) to show that the Boeing 737 Next Generation series aircraft would be more fuel-efficient than the McDonnell-Douglas DC-9-30 aircraft on various routes used by Delta Airlines out of Atlanta\u27s Hartsfield-Jackson International Airport. Databases, such as Aircraft Situation Display to Industry (ASDI) and Base of Aircraft Data (BADA), were used to simulate the baseline flight route information. Simulations were performed on Boeing 737NG (-700, -800, -900) and the DC-9-30 aircraft. Statistically significant improvements were found in the fuel burn for the Boeing 737 aircraft, with an estimated yearly savings of about $26 million dollars
Topological geodesics and virtual rigidity
We introduce the notion of a topological geodesic in a 3-manifold. Under
suitable hypotheses on the fundamental group, for instance word-hyperbolicity,
topological geodesics are shown to have the useful properties of, and play the
same role in several applications as, geodesics in negatively curved spaces.
This permits us to obtain virtual rigidity results for 3-manifolds.Comment: Published by Algebraic and Geometric Topology at

Microstructural evolution in coated conventionally cast Ni-based superalloys
The aim of this research project was to investigate the microstructural changes of MCrAlY coated
Ni-based superalloys that are routinely used in industrial gas turbine engines for power
generation. One of the main aims of the characterisation was to understand ageing time and
temperature effects on the microstructural evolution so that a methodology could be developed
where the characterisation of a thermally exposed microstructure can be used to estimate
unknown service exposure conditions. [Continues.
