Competencies Required for Digital Curation: An Analysis of Job Advertisements
With digital curation’s increasingly important role in the fast-paced and data-intensive information environment, there is a need to identify a set of competencies for professionals in this growing field. As part of a curriculum development project funded by the U.S. Institute of Museum and Library Services, a total of 173 job advertisements posted between October 2011 and April 2012 were collected from various sources to take into account varying types of professionals in the field of digital curation across North America. Position title, institution types and location, educational background, experience, knowledge and skills, and duties were examined and analyzed. The results of the analysis show that digital curation jobs are characterized by a complex interplay of various skills and knowledge. The findings of this study present emerging requirements for a qualified workforce in the field of digital curation
Management of Cloud systems applied to eHealth
This thesis explores techniques, models and algorithms for an efficient management of Cloud
systems and how to apply them to the healthcare sector in order to improve current treatments. It
presents two Cloud-based eHealth applications to telemonitor and control smoke-quitting and
hypertensive patients. Different Cloud-based models were obtained and used to develop a Cloudbased
infrastructure where these applications are deployed. The results show that these
applications improve current treatments and that can be scaled as computing requirements grow.
Multiple Cloud architectures and models were analyzed and then implemented using different
techniques and scenarios. The Smoking Patient Control (S-PC) tool was deployed and tested in a
real environment, showing a 28.4% increase in long-term abstinence. The Hypertension Patient
Control (H-PC) tool, was successfully designed and implemented, and the computing boundaries
were measuredAquesta tesi explora tèniques, models i algorismes per una gestió eficient en sistemes al Núvol i

Research data management in public universities in Malawi
Philosophiae Doctor - PhDThe emergence and subsequent uptake of Information and Communication Technologies has
transformed the research processes in universities and research institutions across the globe.
One indelible impact of Information and Communication Technologies on the research process
is the increased generation of research data in digital format.
This study investigated how research data has been generated, organised, shared, stored,
preserved, accessed and re-used in Malawian public universities with a view to proposing a
framework for research data management in universities in Malawi. The objectives of the
study were: to determine research data creation, sharing and re-use practices in public
universities in Malawi; to investigate research data preservation practices in public universities
in Malawi; to investigate the competencies that librarians and researchers need to effectively
manage research data; and to find out the challenges that affect the management of research
data in public universities in Malawi.
Apart from being guided by the Community Capability Model Framework (Lyon, Ball, Duke
& Day, 2011) and Data Curation Centre Lifecycle Model (Higgins, 2008), the study was
inspired by the pragmatic school of thought which is the basis for a mixed methods research
enabling the collection of quantitative and qualitative data from two purposively selected
universities. A census was used to identify researchers and librarians while purposive sampling
was used to identify directors of research. Questionnaires were used to collect mostly
quantitative and some qualitative data from 36 librarians and 187 researchers while interviews
were conducted with directors of research. The Statistical Package for the Social Sciences was
used to analyse the quantitative data by producing percentages, means, independent samples ttest
and one-way analysis of variance. Thematic analysis was used to analyse the qualitative
data
Parallel and Distributed Execution of Model Management Programs
The engineering process of complex systems involves many stakeholders and development artefacts. Model-Driven Engineering (MDE) is an approach to development which aims to help curtail and better manage this complexity by raising the level of abstraction. In MDE, models are first-class artefacts in the development process. Such models can be used to describe artefacts of arbitrary complexity at various levels of abstraction according to the requirements of their prospective stakeholders. These models come in various sizes and formats and can be thought of more broadly as structured data. Since models are the primary artefacts in MDE, and the goal is to enhance the efficiency of the development process, powerful tools are required to work with such models at an appropriate level of abstraction. Model management tasks – such as querying, validation, comparison, transformation and text generation – are often performed using dedicated languages, with declarative constructs used to improve expressiveness. Despite their semantically constrained nature, the execution engines of these languages rarely capitalize on the optimization opportunities afforded to them. Therefore, working with very large models often leads to poor performance when using MDE tools compared to general-purpose programming languages, which has a detrimental effect on productivity. Given the stagnant single-threaded performance of modern CPUs along with the ubiquity of distributed computing, parallelization of these model management program is a necessity to address some of the scalability concerns surrounding MDE. This thesis demonstrates efficient parallel and distributed execution algorithms for model validation, querying and text generation and evaluates their effectiveness. By fully utilizing the CPUs on 26 hexa-core systems, we were able to improve performance of a complex model validation language by 122x compared to its existing sequential implementation. Up to 11x speedup was achieved with 16 cores for model query and model-to-text transformation tasks
Design of tool management systems for flexible manufacturing systems
The objective of this thesis is to study the design and analysis of tool management system
in the automated manufacturing systems.
The thesis is focused on two main areas, namely design and experiment. In the first part
of the thesis, the design facility created has been reported. The model has been designed using
a hybrid approach in which the power of both algorithmic and knowledge based approaches is
utilised. Model permits detail, more accurate and complete solutions for the management of
tools in a generic manufacturing system.
In the second part of the thesis, to add more understanding to the tool management
problems, the interactions of the major tool management design parameters have been
investigated using a well known design technique, the Taguchi method. For this purpose, a large
number of design experiments have been configured where some have been suggested by the
Taguchi method and some have been created by the author to add more confidence, using a
large body of real industrial data. The experiments results give deeper understanding of TMS
problems and allow design guide-lines to be drawn for the designers.
The design approach and the experiments have been proven to be an accurate and valid
tool for the design of tool management systems for automated manufacturing systems. This is
indicated in the conclusion of the thesis
