Domain Names in Turkey
No full textTurkey faces both unique and common domain name regulatory issues. In this paper, the author focuses on the challenges ahead for Turkey, with especial focus on the regulation of IDNs
Plagiarism: concepts and contexts
No full textAfter outlining the key difficulties in modern literature on academic plaigarism, the author suggests that these may be resolved by a new model of plaigarism (whilst noting that this new model does raise additional uncertainties, e.g. as to the status of 'self plagiarism') that she has developed
Dictionary of Acoustics
No full textThe science and technology of acoustics embraces an unusually wide range of disciplines, from aircraft noise reduction to ultrasonics in medicine, from psychoacoustics to signal processing. The student of acoustics has to become familiar with a corresponding range of specialist terms in order to communicate with others and to understand the literature. Here, in one informative dictionary, for the first time, are listed accurate and helpful definitions to provide the student - or the specialist from another discipline - with a point of entry into the world of acoustics. The dictionary's 2,800 entries cover most of the essential concepts and terminology that the practicing acoustician needs to understand, outside the subfields of music and speech communication. The author has drawn on experience gained during a long career spent mostly at Southampton University's multidisciplinary Institute of Sound and Vibration Research, supplemented by the expertise and perspective of a team of subject specialists
Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
Diffusion weighted magnetic resonance imaging of compromised tissue in stroke
No full textDiffusion weighted imaging (DWI) and T2 weighted magnetic resonance imaging were performed on at least two occasions in 28 children presenting with stroke. In previous reports of DWI in human stroke, eventual infarction was observed (with only one exception) in all regions in which early DWI hyperintensity occurred. In the present report, two children had regions of DWI hyperintensity which did not progress to infarction. One patient who presented with right hemiplegia showed extensive high signal on DWI, with T2 evidence of tissue swelling but without hyperintensity. DWI changes persisted over weeks, with no imaging indication of infarction. This child recovered completely. A second child who had a major vessel infarct with concomitant regions of hyperintensity on T2 weighted imaging and DWI, also had DWI hyperintensity in an adjacent territory which did not develop any subsequent evidence of infarction. Thus in clinical practice DWI can demonstrate tissue which is compromised but not irreversibly so.</p
Modelling of turbulent jets and wall layers: extensions of Lighthill's acoustic analogy with application to computational aeroacoustics
No full textTwo extensions to Lighthill’s aeroacoustic analogy are presented. First, equivalent sources due to initial conditions are derived that supplement those due to boundary conditions, as given by Ffowcs Williams & Hawkings. The resulting exact inhomogeneous wave equation is then reformulated with pressure rather than density as the wave variable, and the right-hand side is rearranged using the energy equation with no additional assumptions. Applications to computational aeroacoustics are discussed, and illustrated with examples based on 2D and 3D simulations
Coauthor prediction for junior researchers
No full textResearch collaboration can bring in different perspectives and generate more productive results. However, finding an appropriate collaborator can be difficult due to the lacking of sufficient information. Link prediction is a related technique for collaborator discovery; but its focus has been mostly on the core authors who have relatively more publications. We argue that junior researchers actually need more help in finding collaborators. Thus, in this paper, we focus on coauthor prediction for junior researchers. Most of the previous works on coauthor prediction considered global network feature and local network feature separately, or tried to combine local network feature and content feature. But we found a significant improvement by simply combing local network feature and global network feature. We further developed a regularization based approach to incorporate multiple features simultaneously. Experimental results demonstrated that this approach outperformed the simple linear combination of multiple features. We further showed that content features, which were proved to be useful in link prediction, can be easily integrated into our regularization approach. © 2013 Springer-Verlag

Proposed mechanisms for the oxidation of methane into methyl hydrogen sulfate with transition metal species of vanadium or silver
No full textMethane is a gaseous chemical that can be converted into chemicals of interest useful to industry. However, the grand challenge in methane functionalization is the low reactivity of
methane combined with the very high reactivity of its products. The high reactivity of its products
leads to overoxidation, which in turn leads to low generation of products of interest since over
oxidation leads to the formation of carbon dioxide. The goal of my research projects hereafter is
to selectively oxidize methane into the chemical methyl hydrogen sulfate (MHS), which can be
hydrolyzed into the commodity chemical of methanol. This is done by combining using transition
metals catalysts coupled with electrochemistry in a two-chamber electrochemical system.
Moreover, another aspect of my projects has been to propose electrochemical mechanisms for the
electrochemical reactions. The first part of my dissertation focuses on using a vanadium molecular
catalyst (chapter 2) to selectively oxidize methane electrocatalytically into MHS. Similarly, the
second part of this dissertation focuses on the selective oxidation of methane into MHS by using
a molecular silver catalyst (chapter 3). Both research projects of vanadium and silver molecular
catalysts both use electrochemistry as the driving force at ambient conditions of room pressure and
room temperature, however, the electrolyte used in the chemical reactions is not mild. The
electrochemical reaction used 98% concentrated sulfuric acid. While room pressure and
temperature is a big focus of the projects, there are studies in the research projects that utilize
elevated pressures and temperatures. The use of elevated temperatures and pressures allows us to
conduct experiments, which can give us an insight into the electrochemical mechanism that is
occurring during the electrolysis reactions. To my knowledge, methane oxidation at room
temperature and room pressure had not been seen before with a homogenous catalyst, so the
innovation of my project is successfully proving that it is possible to oxidize methane at ambient
conditions with a homogenous catalyst while proposing an electrochemical mechanism for the
reactions
