Emulation of dynamic computer models with multivariate output

This preliminary report describes work carried out as part of work package 1.2 of the MUCM research project. The report is split in two parts: the ?rst part (Sections 1 and 2) summarises the state of the art in emulation of computer models, while the second presents some initial work on the emulation of dynamic models. In the ?rst part, we describe the basics of emulation, introduce the notation and put together the key results for the emulation of models with single and multiple outputs, with or without the use of mean function. In the second part, we present preliminary results on the chaotic Lorenz 63 model. We look at emulation of a single time step, and repeated application of the emulator for sequential predic- tion. After some design considerations, the emulator is compared with the exact simulator on a number of runs to assess its performance. Several general issues related to emulating dynamic models are raised and discussed. Current work on the larger Lorenz 96 model (40 variables) is presented in the context of dimension reduction, with results to be provided in a follow-up report. The notation used in this report are summarised in appendix.

Model-driven software adaptation:report on the workshop M-ADAPT at ECOOP 2007

This first edition of the workshop Model-driven Software Adaptation (M-ADAPT'07) took place in the Technische Universität Berlin with the International Conference ECOOP'07 in the beautiful and buzzing city of Berlin, on the 30th of July, 2007. The workshop was organized by Gordon Blair, Nelly Bencomo, and Robert France. Participants explored how to develop appropriate model-driven approaches to model, analyze, and validate the volatile properties of the behaviour of adaptive systems and its environments. This report gives an overview of the presentations as well as an account of the fruitful discussions that took place at M-ADAPT'07. © 2008 Springer-Verlag Berlin Heidelberg.

Web-based report generators, data visualization, and Web-to-database connectivity

Because some Web users will be able to design a template to visualize information from scratch, while other users need to automatically visualize information by changing some parameters, providing different levels of customization of the information is a desirable goal. Our system allows the automatic generation of visualizations given the semantics of the data, and the static or pre-specified visualization by creating an interface language. We address information visualization taking into consideration the Web, where the presentation of the retrieved information is a challenge. ^ We provide a model to narrow the gap between the user's way of expressing queries and database manipulation languages (SQL) without changing the system itself thus improving the query specification process. We develop a Web interface model that is integrated with the HTML language to create a powerful language that facilitates the construction of Web-based database reports. ^ As opposed to other papers, this model offers a new way of exploring databases focusing on providing Web connectivity to databases with minimal or no result buffering, formatting, or extra programming. We describe how to easily connect the database to the Web. In addition, we offer an enhanced way on viewing and exploring the contents of a database, allowing users to customize their views depending on the contents and the structure of the data. Current database front-ends typically attempt to display the database objects in a flat view making it difficult for users to grasp the contents and the structure of their result. Our model narrows the gap between databases and the Web. ^ The overall objective of this research is to construct a model that accesses different databases easily across the net and generates SQL, forms, and reports across all platforms without requiring the developer to code a complex application. This increases the speed of development. In addition, using only the Web browsers, the end-user can retrieve data from databases remotely to make necessary modifications and manipulations of data using the Web formatted forms and reports, independent of the platform, without having to open different applications, or learn to use anything but their Web browser. We introduce a strategic method to generate and construct SQL queries, enabling inexperienced users that are not well exposed to the SQL world to build syntactically and semantically a valid SQL query and to understand the retrieved data. The generated SQL query will be validated against the database schema to ensure harmless and efficient SQL execution. (Abstract shortened by UMI.)^

A ROS-based Workspace Control and Trajectory Planner for a seven degrees of freedom Robotic arm

In this Bachelor Thesis I want to provide readers with tools and scripts for the control of a 7DOF manipulator, backed up by some theory of Robotics and Computer Science, in order to better contextualize the work done. In practice, we will see most common software, and developing environments, used to cope with our task: these include ROS, along with visual simulation by VREP and RVIZ, and an almost "stand-alone" ROS extension called MoveIt!, a very complete programming interface for trajectory planning and obstacle avoidance. As we will better appreciate and understand in the introduction chapter, the capability of detecting collision objects through a camera sensor, and re-plan to the desired end-effector pose, are not enough. In fact, this work is implemented in a more complex system, where recognition of particular objects is needed. Through a package of ROS and customized scripts, a detailed procedure will be provided on how to distinguish a particular object, retrieve its reference frame with respect to a known one, and then allow navigation to that target. Together with technical details, the aim is also to report working scripts and a specific appendix (A) you can refer to, if desiring to put things together.

'Scratch' locative audio drama - report to BBC executives on trial at BBC FreeThinking 2008

‘Scratch’ investigates the use of physical space as a representation of narrative and dramatic structure. An audio-drama, it is a world-first in being location-sensitive without being tied to any particular place (preceding attempts by others have emphasised location-specific aspects of the genre). Developed in collaboration with and part-funded by BBC Radio Drama, it builds on research undertaken for ‘Dragons’ (output 4). It uses pre-recorded audio on GPS-enabled mobile devices allowing sounds to be virtually attached to locations in an outdoor space. As participants move, they encounter scenes forming a coherent drama which behave differently if the same place is visited more than once. This translocational approach opens novel artistic possibilities exploited through team expertise in narrative, sound design and advanced interaction. It is also significant in the economics of broadcast media as a more viable proposition than the many experimental locative experiences which have been site-specific: this was of great interest to the BBC. The public performance selected for BBC FreeThinking, 1-2 September 2008 in Liverpool as part of European Capital of Culture was reported in a co-authored 2009 conference presentation at ISEA, Belfast, 26-29 August 2009 and in a co-authored short chapter in Spierling and Szilas (eds.) Interactive Storytelling, Springer 2008. Boyd Davis directed the project and devised and undertook the evaluation with 40 trial listeners, reporting to BBC executives (http://researchonline.rca.ac.uk/1000/) for whom a second trial was also run in London in 2009. The evaluation used interview, video observation and a questionnaire combining an open question at the beginning with more specific questions later, avoiding channelling respondents' reactions immediately after the experience into issues which might not be uppermost in their minds, while also yielding data capable of rigorous analysis. The evaluation was to provide feedback to the makers of the drama and to guide policy at the BBC. [287] Participants were recruited principally through the publicity for FreeThinking 2008 – mainly via the festival website. The average age of participants was 40. The gender of participants was 20 males, 17 females and 3 null returns. The evaluation strategy was to combine an open question at the beginning with more specific questions later. In this way we avoided channeling respondents' initial opinions immediately after the experience into issues which might not be uppermost in their minds, while also yielding data capable of rigorous analysis. The purpose of the evaluation was to provide guidance for ourselves as the makers of the drama and to guide policy at the BBC on locative and other interactive media. The responses are analysed in the report.

Direct Numerical Simulation of Turbulent Flames

The present paper is a report on progress in the simulation of turbulent flames using the Cray T3D and T3E at the Edinburgh parallel computing centre, using codes developed in Cambridge. Two combustion DNS codes are described, ANGUS and SENGA, which solve incompressible and fully compressible reacting flows respectively. The technical background to combustion DNS is presented, and the resource requirements explained in terms of the physic and chemistry of the problem. Results for flame turbulence interaction studies are presented and discussed in terms of their relevance to modelling. Recent work on the fully compressible problem is highlighted and future directions outlined.
