Children and Disasters: A tribute to Professor Kevin Ronan
No full text(c) The Author/sIn 1997, Professor Kevin Ronan published a paper in the first ever edition of the Australasian Journal of Disaster and Trauma Studies, titled “The Effects of a “Benign” Disaster: Symptoms of Post-traumatic Stress in Children Following a Series of Volcanic Eruptions”. Over the next 23 years, Kevin and his many colleagues pursued aspects of children and disasters to both improve practice and advance scholarship in this area. In March 2020 we were saddened by the untimely passing of Kevin. As a tribute to Professor Ronan this special issue of the Australasian Journal of Disaster and Trauma Studies brings together accounts of current research and practice initiatives inspired by, building upon, and directly influenced by Professor Ronan’s work
Continuous metadata flows for distributed multimedia
No full textThe practical use of temporal multimedia has increased markedly in recent years as enabling technologies for the distribution and streaming of media have become available. As a part of this trend, hypermedia systems and models have adapted accordingly to incorporate such distributed multimedia for presentation. Structured interpretation of information has long been a fundamental feature of both open hypermedia systems and knowledge systems. Metadata, in its many forms, has become the cornerstone for providing this structured knowledge above and beyond basic data and information. This thesis presents the rationale and requirements for continuous metadata, which supports the metadata accompanying distributed multimedia throughout the lifecycle of streamed media, from generation, through distribution, to presentation. Throughout this process it is the temporal and continuous nature of the metadata which is paramount. A conceptual framework for continuous metadata is proposed to encapsulate these principles and ideas. Continuous metadata and the associated framework enable the development, in particular, of real-time, collaborative, semantically enriched distributed multimedia applications. Experience building one such system using continuous metadata is evaluated within the framework. An ontology is developed for the system to enable the collation, distribution, and presentation of structure aiding navigation of multimedia, and it is shown how continuous metadata utilising the ontology can be distributed using multicas
Optimizing fully homomorphic encryption
No full textThesis: M. Eng., Massachusetts Institute of Technology, Department of Electrical Engineering and Computer Science, 2016.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student-submitted PDF version of thesis.Includes bibliographical references (pages 50-51).Fully homomorphic encryption (FHE) presents the possibility of removing the need to trust cloud providers with plaintext data. We present two new FHE scheme variants of BGV'12, both of which remove the need for key switching after a ciphertext multiplication, overall halving the runtime of bootstrapping. We also present multiple implementations of 32-bit integer addition evaluation, the fastest of which spends 16 seconds computing the addition circuit and 278 seconds bootstrapping. We nd that bootstrapping consumes approximately 90% of the computation time for integer addition and secure parameter settings are currently bottlenecked by the memory size of commodity hardware.by Kevin C.

Gillen, All Rights Reserved. Q: What are the Philadelphia House Price Indices? A: The Philadelphia house price indices (hereafter, HPIs) are a set of indices characterizing the average rate of appreciation in Philadelphia house values over time. They are analogous to a Dow Jones Index, but for house prices rather than stock prices: although the actual level of the indices does not mean much, the change in the index from one time period to another does. In particular, the indices are estimated in such a way so that the percent change in the index over any time period should be representative of the average percent change i
Pancreatic anastomosis after pancreatoduodenectomy: A position statement by the International Study Group of Pancreatic Surgery (ISGPS)
No full textClinically relevant postoperative pancreatic fistula (grades B and C of the ISGPS definition) remains the most troublesome complication after pancreatoduodenectomy. The approach to management of the pancreatic remnant via some form of pancreatico-enteric anastomosis determines the incidence and severity of clinically relevant postoperative pancreatic fistula. Despite numerous trials comparing diverse pancreatico-enteric anastomosis techniques and other adjunctive strategies (pancreatic duct stenting, somatostatin analogues, etc), currently, there is no clear consensus regarding the ideal method of pancreatico-enteric anastomosis
Entity-relation search: context pattern driven extraction and indexing
No full textOur research focuses on searching relations between entities with context constraints. In particular, we are interested in efficiently searching for the relations among medical entities (e.g. diseases, chemicals, species, genes, or mutations) in a professional medical corpus. Existing relation extraction systems, like OpenIE, are able to extract some relations between entities. However, its results are inseparable in terms of extraction contexts, which prevents it from being able to search for the relations of given contexts.
To address this issue, we propose to build an entity-relation search system with an awareness of extraction contexts. In order to achieve this goal, we propose to extract and index contexts for each extracted relation. We evaluate our search model over millions of professional medical abstracts and show that our context indexing is effective to support the task of searching relations into contexts.
Note that this rich and novel system is the product of a collaborative team effort: Tianxiao Zhang, Jiarui Xu and Varun Berry, and supervised by Professor Kevin Chang. While we separately document our individual contributions, we intentionally share some parts of our thesis to improve the readability of our overall system design. This thesis mainly focuses on the design of our context extraction and indexing method.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-12-01The student, Zequn Zhang, accepted the attached license on 2016-12-02 at 14:07.The student, Zequn Zhang, submitted this Thesis for approval on 2016-12-02 at 14:13.This Thesis was approved for publication on 2016-12-05 at 13:33.DSpace SAF Submission Ingestion Package generated from Vireo submission #10421 on 2017-02-28 at 14:43:12Made available in DSpace on 2017-03-01T17:02:02Z (GMT).
