An information states blackboard as an intelligent querying interface for snow and avalanche data

We present the graph-based querying paradigm used in the Regional Avalanche Information and Forecasting System (RAIFoS) for the collection and analysis of snow and weather related physical parameters in the Swiss Alps. The querying paradigm relies upon the issue of interactively constructing a semantically valid query graph on an Information States Blackboard as guided by meta-data elements standing for interpretations of conceptual model, data values and/or operations. The meta-data elements constitute the terms of a meta-data-driven query language (MDDQL) the interpretation of which is done interactively relying on a kind of finite state automaton

Context based querying of scientific data: changing querying paradigms?

We are investigating and applying a semantically enhanced query answering machine for the needs of addressing semantically meaningful data and operations within a scientific information system. We illustrate a context based querying paradigm on the basis of a Regional Avalanche Information and Forecasting System - RAIFoS which is concerned with the collection and analysis of snow and weather related physical parameters in the Swiss Alps. The querying paradigm relies upon the issue of interactively constructing a semantically valid query rather than formulating one in a database specific query language and for a particular implementation model. In order to achieve this goal, the query answering machine has to make inferences concerning the properties and value domains, as well as data analysis operations, which are semantically valid within particular contexts. These inferences take place when the intended query is being constructed interactively on a Web-based blackboard. A graph-based display presentation formalism is used with elements including natural language terms, measurement units, statistical quantifiers and/or specific value domains. A meta-data database is used to organise and provide the elements of the graph each time the graph, and consequently the intended query, is expanded or further refined. Finally, the displayed graph is transformed into elements of the implementation model from which, in turn, SQL statements and/or sequences of statistical operations are created

The haunted university: academic subjectivity in the time of communicative capitalism

In the last thirty years there have been significant changes in the governmentality and culture of higher education in the UK; concurrently, day-to-day practice has been transformed by networked computers. This political and technical double-act may be understood as a specific articulation of what Jodi Dean has termed communicative capitalism (2010, p.2-9). This thesis investigates how such political and technocultural changes condition the subjectivity of academic staff across a range of academic activities and contexts. The theoretical model I develop draws notably on a combination of the psychoanalytic theory of Freud and Lacan, using Freud’s conception of the ‘uncanny’ (1919) and Althusser’s theory of ideology (1970), to consider how the academic subject of technoculture is constituted by the particular domain of communicative capitalism I term the Haunted University. To develop this argument the thesis firstly establishes the ‘nature’ of the contemporary university – distinguishing it from earlier models and earlier moments of reform. This is developed using cultural history sources and theoretical work from social, cultural and critical higher education studies. Secondly, I use a series of cultural studies methods to identify and explore elements of the new university formation. These include the selection and analysis of relevant digital materials (e.g. academic homepages and blogs) and small qualitative surveys of academic staff. Thirdly, the broadly Lacanian thrust of my argument is developed through leveraging theoretical work from the fields of cultural studies, philosophy, critical labour studies and higher education policy. I conclude that the series of developments and changes enacted by communicative capitalism has tended to transform academic subjectivity, bringing about what may be a permanent change in the ontology and epistemology of the academy. However, despite neoliberalism’s attempt to foreclose discursive dissent, there are resistances to its project. My original contribution to knowledge is to theorise how and why the shift in academic subjectivity is being enacted, demonstrating how the technocultural, neoliberal university is beginning to haunt the academy not only from the outside, but from the inside, too

Reinventing the Social Scientist and Humanist in the Era of Big Data

This book explores the big data evolution by interrogating the notion that big data is a disruptive innovation that appears to be challenging existing epistemologies in the humanities and social sciences. Exploring various (controversial) facets of big data such as ethics, data power, and data justice, the book attempts to clarify the trajectory of the epistemology of (big) data-driven science in the humanities and social sciences

First Annual Workshop on Space Operations Automation and Robotics (SOAR 87)

Several topics relative to automation and robotics technology are discussed. Automation of checkout, ground support, and logistics; automated software development; man-machine interfaces; neural networks; systems engineering and distributed/parallel processing architectures; and artificial intelligence/expert systems are among the topics covered

Using MapReduce Streaming for Distributed Life Simulation on the Cloud

Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp

A study of the role of an Unmanned Aerial Vehicle (UAV) in creating an Enhanced Virtual Field Guide (EVFG) in Geoscience Fieldwork

This thesis investigated the role of an Unmanned Aerial Vehicle (UAV) in the creation of an Enhanced Virtual Field Guide (EVFG) in Geoscience fieldwork. This research used a pragmatic mixed methods approach to investigate the research question “How can an Unmanned Aerial Vehicle’s data be used to create an Enhanced Virtual Field Guide for Geoscience fieldwork?” The thesis examines the question in four distinct sections; fieldwork, mobile technologies in fieldwork, UAVs in fieldwork and finally, the creation and evaluation of the Enhanced Virtual Field Guide created by UAV technology. To achieve this, online questionnaires, interviews, focus groups and fieldwork observations with a selection of Geoscience staff and students at two UK Universities were utilised. UAVs are a rapidly emerging commercial technology, however, their uptake and critical discussion around their potential in fieldwork with students has been limited. This study created with the guidance of those interviewed in this research, an innovative Enhanced Virtual Field Guide for students to utilise in their final year fieldwork module and assignment. Findings from this research with regards to fieldwork and mobile technologies confirms that fieldwork and mobile technologies are still an integral part of a geoscience students course and the majority of students still greatly enjoy the positive aspects of fieldwork. However, this research has discovered many unexplored darker sides of fieldwork and mobile technology use in fieldwork, such as disabilities, distractions, and lack of access for some students. In terms of the educational value of UAVs, this research showcases the many potential benefits for the fieldwork experience. Yet, this thesis highlights the many distinct and unique challenges that are attributed to UAV technologies that have and will continue to hinder their uptake on fieldwork. The value of this EVFG developed from a UAV has been shown to be a useful tool for educators and students on fieldwork as examined in this thesis, such as an improvement of efficiency in the field, deeper and more peer learning discussions in the field and for it to be an effective learning tool for both educators and students, particularly post-fieldwork
