Web-Based Integrated Research Environment for Aerodynamic Analyses and Design

e-AIRS[1,2], an abbreviation of ‘e-Science Aerospace Integrated Research System,’ is a virtual organization designed to support aerodynamic flow analyses in aerospace engineering using the e-Science environment. As the first step toward a virtual aerospace engineering organization, e-AIRS intends to give a full support of aerodynamic research process. Currently, e-AIRS can handle both the computational and experimental aerodynamic research on the e-Science infrastructure. In detail, users can conduct a full CFD (Computational Fluid Dynamics) research process, request wind tunnel experiment, perform comparative analysis between computational prediction and experimental measurement, and finally, collaborate with other researchers using the web portal. The present paper describes those services and the internal architecture of the e-AIRS system.

Development of v-DMU Based on e-Science Using COVISE and SAGE

Virtual digital mock-up (v-DMU) refers to all of the activities in the design, analysis, and visualization of the product in a 3D virtual environment that lead to a lower cost and a higher quality. In the early days, designers exchanged CAD files directly in collaborations. Recently, DMU systems have been used for relatively effective designs that generally support distributed and collaborative design capability by sharing the design data via the Internet. However, a range of problems can arise in such a case. In the case of large-scale products such as aircrafts or ships, the data size can be on a scale so large that it requires large amount of space on the workstation and requires considerable time for exchanges. Moreover, security problems often occur in the process of data exchanges. For a company and a nation, this can be crucial. The immersive visualization of product design data is becoming more important in collaborative design. As a solution to these issues, this paper proposes a new approach using the technology of the remote visualization of CAD data. This involves the streaming of rendered graphics using COVISE and SAGE. This paper also introduces the implementation of v-DMU based on e-Science by remote visualization.

Design of a Four Degree_of_Freedom Manipulator for Northern Light Mars Mission

Northern Light is a Canadian mission to Mars, currently developed by a team of engineers, scientists and industrial organizations. The mission objectives include scientific goals such as the search for life and water, preparation for a sample return and engineering goals including the demonstration of interplanetary travel, an entry, descent and landing system, a rover design, a manipulator/drilling system, and semi-autonomous control in remote operations. The Northern Light team at York University is developing a four degree-of-freedom manipulator system, specifically for this remote operation. The Northern Light manipulator system will be mounted directly on the lander (not on the rover), providing an opportunity to perform scientific missions directly from the lander. The drilling instrument, to be mounted on the manipulator, is currently under development by Dr. Tze Chuen Ng now with the help of Hong Kong’s Polytechnics University. The operation concept is based on a “single command cycle” approach. The operation plans are designed to handle exceptions, failures and unforeseen events using local intelligence and a contingency planner.

Design and Application of GeoNet System for ABC Cooperative Environment

The Atmospheric Brown Cloud (ABC) project is an international research effort initiated by the United Nations Environment Program (UNEP). However, lack of cooperative application system for the collected ground measurement data from ABC observatories, prevents intimate cooperative studies among the researchers. In our proposal, therefore, we establish an e-Science based cooperative web environment called GeoNet(Global Earth Observation Network) so that ABC scientists can effectively share and utilize the ABC data. Therefore, ABC scientists can share and manage more effectively satellite images from various satellites and collected ground measurement data from ABC observatories through GeoNet.

York University Space Engineering Nanosatellite Demonstration (YuSend) Mission Development

In this paper, we review the York University Space Engineering Nanosatellite Demonstration (YuSend) program. We have identified several possible missions for CubeSat-based nanosatellites and associated enabling technologies. The potential applications for the tiny spacecraft (weighing 1kg each) include on-orbit servicing, assembly and monitoring, stereo imaging, formation flying, and GPS occultation experiments. While there are many challenges to be faced in nanosatellite design, the group is focusing on three key areas of research: power management, attitude control and autonomous mission planning. The details of current research related to the above three areas are discussed here. The objective is to demonstrate the technology to perform formation flying and on-orbit servicing using a modular power unit, thruster, and automated mission planner. This paper describes the conceptual design of York’s first satellite, the YuSend-1 spacecraft.

A Dynamic Bridge for Data Sharing on e-Science Grid Implementing Web 2.0 Service

This paper proposes a dynamic bridge for e-Science Grid, implementing Web 2.0 service in order to share experimental data effectively.An e-Science Grid has been established as a cyber laboratory for the users with a special research purpose on science. As an open space, e-Science Grid is expected to stimulate the collaborative researches and the cross domain ones. These research trends need a more efficient and convenient data service satisfying the science researchers. A dynamic bridge designed based on HVEM DataGrid, satisfies the users’ requirements for the data sharing on e-Science Grid effectively. It supports a data tagging service in order for HVEM DataGrid to be utilized more extensively without any modification of the existing Grid architecture or services. Moreover, it can be adopted and deleted easily without any effect to the legacy Grid. With the legacyinterface to access data in e-Science Grid, the data tags endow the Grid with the flexibility for data access. This paper evaluates the usefulness of the dynamic bridge by analyzing its overhead and performance.

A Grid Middleware Framework Support for a Workflow Model Based on Virtualized Resources

Nowadays, the virtualization technologies are widely used to overcome the difficulty of managing Grid computing infrastructures. The virtual account and the virtual workspace are very optimistic to allocate Grid resources to specific user, but they lacks of capability of interaction between portal services and virtualized resources which required by Grid portal. The virtual application is fitted to wrap simple application as a Grid portal service, but integrating some applications to compose larger application service is difficult. In this paper, we present a Grid middleware framework which supports for a workflow model based on virtualized resources. Meta Services in the framework exposes workflow as a portal service and service call is converted different workflow according to parameter and workflow generated by the Meta Services is scheduled in a virtual cluster which configured by this framework. Because of virtual application service can be composed of workflow and service interface wraps the workflow providing a complex portal services composed by small application could effectively integrated to Grid portal and scheduled in virtual computing resources.

An Approach to Multi-Objective Aircraft Design

Aircraft design is a complex process subject to many competing disciplinary analyses and is constrained by many performance targets, airworthiness requirements, environmental regulations, and many other factors. Designers must explore a broad range of possible decisions to find the best trade-offs between many competing performance goals and design constraints while ensuring that the resulting design complies with certification and airworthiness standards. A modular Multi-Disciplinary Optimization (MDO) framework is being developed with the ability to handle multiple simultaneous objectives while considering any airworthiness constraints that can be assessed at the conceptual level. The algorithm implements a multi-objective Genetic Algorithm (GA) within an MDO framework. The problem consists of four core disciplinary analysis including structural weight estimation, aerodynamics, performance, and stability.

Experiences and Requirements for Interoperability Between HTC and HPC-driven e-Science Infrastructure

Recently, more and more e-science projects require resources in more than one production e-science infrastructure, especially when using HTC and HPC concepts together in one scientific workflow. But the interoperability of these infrastructures is still not seamlessly provided today and we argue that this is due to the absence of a realistically implementable reference model in Grids. Therefore, the fundamental goal of this paper is to identify requirements that allows for the definition of the core building blocks of an interoperability reference model that represents a trimmed down version of OGSA in terms of functionality, is less complex, more fine-granular and thus easier to implement. The identified requirements are underpinned with gained experiences from world-wide interoperability efforts.

Interactive Scientific Visualization of High-resolution Brain Imagery Over Networked Tiled Display

In this paper, we discuss our on-going efforts for an interactive scientific visualization of high-resolution brain imagery over networked tiled display. It targets to visualize a brain in both 2D and 3D. It also supports multiple highresolution displays of brain images by integrating networked tiled display while providing interactive control of display resolution and view direction. In order to construct an appropriate visualization system for brain imaging researches, we study and compare existing visualization systems using a networked tiled display. Based on this comparison, we integrate visualization features on our brain visualization system. Finally, to verify the usefulness of the proposed approach, an initial implementation of EIT brain image visualization is being made.

Object-Oriented Implementation of the Finite-Difference Time-Domain Method in Parallel Computing Environment

GMES which stands for GIST Maxwell’s Equations Solver is a Python package for a Finite-Difference Time-Domain (FDTD) simulation. The FDTD method widely used for electromagnetic simulations is an algorithm to solve the Maxwell’s equations. GMES follows Object-Oriented Programming (OOP) paradigm for the good maintainability and usability. With the several optimization techniques along with parallel computing environment, we could make the fast and interactive implementation. Execution speed has been tested in a single host and Beowulf class cluster. GMES is open source and available on the web (http://www.sf.net/projects/gmes).

Protein-Protein Interaction Network and Gene Ontology

Evolution of computer technologies makes it possible to access a large amount and various kinds of biological data via internet such as DNA sequences, proteomics data and information discovered about them. It is expected that the combination of various data could help researchers find further knowledge about them. Roles of a visualization system are to invoke human abilities to integrate information and to recognize certain patterns in the data. Thus, when the various kinds of data are examined and analyzed manually, an effective visualization system is an essential part. One instance of these integrated visualizations can be combination of protein-protein interaction (PPI) data and Gene Ontology (GO) which could help enhance the analysis of PPI network. We introduce a simple but comprehensive visualization system that integrates GO and PPI data where GO and PPI graphs are visualized side-by-side and supports quick reference functions between them. Furthermore, the proposed system provides several interactive visualization methods for efficiently analyzing the PPI network and GO directedacyclic- graph such as context-based browsing and common ancestors finding.
