Tools for modelling and simulating migration-based preservation

This report describes two tools for modelling and simulating the costs and risks of using IT storage systems for the long-term archiving of file-based AV assets. The tools include a model of storage costs, the ingest and access of files, the possibility of data corruption and loss from a range of mechanisms, and the impact of having limited resources with which to fulfill access requests and preservation actions. Applications include archive planning, development of a technology strategy, cost estimation for business planning, operational decision support, staff training and generally promoting awareness of the issues and challenges archives face in digital preservation

Intergenerational transmission of attachment. Family interactive dynamics and psychopathology: what kind of relationship in adolescence?

Introduction: this work is an example of empirical research. The aim was to look to the possible transgenerational influence between parents and adolescents attachment bond to their respective parents, infant armonic and/or disarmonic development and functional or dysfunctional family interactions. Methodology: 40 families with adolescents aged from 12 to 18 years (μ = 14.575, σ = 1.716) coming for a psychodiagnostic evaluation were tested with Lausanne Trilogue Play, Parental Bonding Instrument, Child Behaviour Checklist and Youth Self Report. Hypothesis: a) is there an association between the adolescent’s perceived attachment relationship with his parents and his psychopathological symptoms? In this case a non parametric test for k independent groups was performed. b) is there an association between parents-adolescent interactive dynamics and the parents’ perceived attachment relationship with their parents (adolescent’s grand-parents). In this case correlations and non-parametric test for k independent groups were performed. Results: a) we found significant statistical differences (p < .05) between adolescent psychopathology and the quality of perceived relationship with both the mother and the father. b) we found positive correlations between quality of relationship between the mother and her father (adolescent grandfather) and the scores of some LTP scales concerning normative function; moreover we found negative correlations between the father and his mother (adolescent’s grandmother) and the scores of some LTP scales concerning affective function. Conclusion: these results underline a significant association between the internal working model of the mother and her ways to interact and manage the relation with her adolescent son; this is a clinical evidence too. Another relevant result is the association between adolescent’s psychopathology and his internal working model. Clinical applications regarding these findings should be taken in account when psychotherapeutically working with adolescents and their families

Design and semantics of form and movement (DeSForM 2006)

Design and Semantics of Form and Movement (DeSForM) grew from applied research exploring emerging design methods and practices to support new generation product and interface design. The products and interfaces are concerned with: the context of ubiquitous computing and ambient technologies and the need for greater empathy in the pre-programmed behaviour of the ‘machines’ that populate our lives. Such explorative research in the CfDR has been led by Young, supported by Kyffin, Visiting Professor from Philips Design and sponsored by Philips Design over a period of four years (research funding £87k). DeSForM1 was the first of a series of three conferences that enable the presentation and debate of international work within this field: • 1st European conference on Design and Semantics of Form and Movement (DeSForM1), Baltic, Gateshead, 2005, Feijs L., Kyffin S. & Young R.A. eds. • 2nd European conference on Design and Semantics of Form and Movement (DeSForM2), Evoluon, Eindhoven, 2006, Feijs L., Kyffin S. & Young R.A. eds. • 3rd European conference on Design and Semantics of Form and Movement (DeSForM3), New Design School Building, Newcastle, 2007, Feijs L., Kyffin S. & Young R.A. eds. Philips sponsorship of practice-based enquiry led to research by three teams of research students over three years and on-going sponsorship of research through the Northumbria University Design and Innovation Laboratory (nuDIL). Young has been invited on the steering panel of the UK Thinking Digital Conference concerning the latest developments in digital and media technologies. Informed by this research is the work of PhD student Yukie Nakano who examines new technologies in relation to eco-design textiles

Process: program for research on operator control in an experimental simulated setting

An experimental tool for the investigation of human control behavior of slowly responding dynamic systems is described. Process (Program for Research on Operator Control in an Experimental Simulated Setting) is a simulation of a dynamic water-alcohol distillation system that is especially useful in research on operator training. In particular, Process was developed to conduct research on fault management skill

Cyberbullying Detection System with Multiple Server Configurations

Due to the proliferation of online networking, friendships and relationships - social communications have reached a whole new level. As a result of this scenario, there is an increasing evidence that social applications are frequently used for bullying. State-of-the-art studies in cyberbullying detection have mainly focused on the content of the conversations while largely ignoring the users involved in cyberbullying. To encounter this problem, we have designed a distributed cyberbullying detection system that will detect bullying messages and drop them before they are sent to the intended receiver. A prototype has been created using the principles of NLP, Machine Learning and Distributed Systems. Preliminary studies conducted with it, indicate a strong promise of our approach

MOLNs: A cloud platform for interactive, reproducible and scalable spatial stochastic computational experiments in systems biology using PyURDME

Computational experiments using spatial stochastic simulations have led to important new biological insights, but they require specialized tools, a complex software stack, as well as large and scalable compute and data analysis resources due to the large computational cost associated with Monte Carlo computational workflows. The complexity of setting up and managing a large-scale distributed computation environment to support productive and reproducible modeling can be prohibitive for practitioners in systems biology. This results in a barrier to the adoption of spatial stochastic simulation tools, effectively limiting the type of biological questions addressed by quantitative modeling. In this paper, we present PyURDME, a new, user-friendly spatial modeling and simulation package, and MOLNs, a cloud computing appliance for distributed simulation of stochastic reaction-diffusion models. MOLNs is based on IPython and provides an interactive programming platform for development of sharable and reproducible distributed parallel computational experiments

IT support to product variety management

Offering to customers a high variety of products while guaranteeing competitive prices and reasonable delivery times is an ever-increasing necessity for companies. At the same time, the growing technological content of products contributes further to this complexity, introducing new challenges to management. As for any area of company activity, the creativity of software producers has brought about the development of information science systems, such as Product Configuration Systems, Product Data Management systems (PDM) and Customer Relationship Management Systems (CRM), which all promise to alleviate the problems caused by this complexity.Product Variety, Product Configuration Systems, Product Data Management Systems, Customer Relationship Management Systems
