Distributed simulation and the grid: Position statements
The Grid provides a new and unrivaled technology for large scale distributed simulation as it enables collaboration and the use of distributed computing resources. This panel paper presents the views of four researchers in the area of Distributed Simulation and the Grid. Together we try to identify the main research issues involved in applying Grid technology to distributed simulation and the key future challenges that need to be solved to achieve this goal. Such challenges include not only technical challenges, but also political ones such as management methodology for the Grid and the development of standards. The benefits of the Grid to end-user simulation modelers also are discussed
Towards collaborative learning via shared artefacts over the Grid
The Web is the most pervasive collaborative technology in widespread use today; and its use to support
eLearning has been highly successful. There are many web-based Virtual Learning Environments such as
WebCT, FirstClass, and BlackBoard as well as associated web-based Managed Learning Environments. In
the future, the Grid promises to provide an extremely powerful infrastructure allowing both learners and
teachers to collaborate in various learning contexts and to share learning materials, learning processes,
learning systems, and experiences. This position paper addresses the role of support for sharing artefacts
in distributed systems such as the Grid. An analogy is made between collaborative software development
and collaborative learning with the goal of gaining insights into the requisite support for artefact sharing
within the eLearning community
Towards the development of the supply chain of concentrated solar power
This work focuses on the investigation into the planning of renewable energy power plants in Brazil using the Concentrated Solar Power (CSP) technology. The main aim of the paper is to present an analysis of the planning process that can be used as a basis of the development of a method to assess the Brazilianâs local manufacturing and supply chain capabilities in supporting the deployment of the CSP technology. The paper identifies areas in which the concerted efforts should be emphasized. For this, the paper will first discuss the key components of the chosen CSP technology (in this case the parabolic through). The manufacturing processes of these components will subsequently be analyzed and the key enabling technologies will be determined. The demands of electricity will be estimated using the System Advisory ModelÂź, a modelling tool developed by the National Renewable Energy Laboratory (NREL). An assessment method will finally be proposed to identify the potentials of the local Brazilian supply chain, through the readiness evaluation of the key enabling technologies and manufacturing processes
Business process management tools as a measure of customer-centric maturity
In application of business process management (BPM) tools in European commercial sectors, this paper examines current maturity of customer centricity construct (CC) as an emerging dimension of competition and as a potential strategic management direction for the future of business. Processes are one of the key components of transformation in the CC roadmap. Particular departments are more customer orientated than others, and processes, customer-centric expertise, and approach can be built and utilized starting from them. Positive items within a current business process that only involve minor modification could be the basis for that. The evidence of movement on the customer-centric roadmap is found. BPM in European telecommunications, banking, utility and retail sector supports roadmap towards customer-centricity in process view, process alignment and process optimization. However, the movement is partial and not flawless, as BPM hasnât been inquired for supporting many of customer-centric dimensions
A collection of tools for factory eco-efficiency
co-efficiency is generally defined as doing more with less, aiming to decouple environmental impact from economic and social value creation.
This paper presents three tools to guide the implementation of eco-efficiency in factories: (1) definition and patterns of good practices for
sustainable manufacturing, (2) a self-assessment tool and maturity grid, and (3) a factory modelling framework
Energy price risk management
The price of electricity is far more volatile than that of other commodities
normally noted for extreme volatility. Demand and supply are balanced on a
knife-edge because electric power cannot be economically stored, end user
demand is largely weather dependent, and the reliability of the grid is
paramount. The possibility of extreme price movements increases the risk of
trading in electricity markets. However, a number of standard financial tools
cannot be readily applied to pricing and hedging electricity derivatives. In
this paper we present arguments why this is the case
Project oriented university â an emerging concept
The purpose of this article is to introduce a brand new concept, that of the project-oriented university, as a university that explicitly uses projects and programmes to perform processes of medium to high complexity, thus allowing it to better handle the increasing turbulence and dynamics of its environments. An analytical grid for assessing the maturity of a university in terms of its project orientation is offered, taking into account both hard and soft factors. The National School for Political Sciences and Public Administration from Bucharest is analysed in this perspective, the assessment being the basis for explaining the paradox of having projects, but no project management. The findings are considered representative for the Romanian higher education system as a whole, with due nuances and exceptions.project maturity, competitive advantage, university, organizational strategy.
A survey on cyber security for smart grid communications
A smart grid is a new form of electricity network with high fidelity power-flow control, self-healing, and energy reliability and energy security using digital communications and control technology. To upgrade an existing power grid into a smart grid, it requires significant dependence on intelligent and secure communication infrastructures. It requires security frameworks for distributed communications, pervasive computing and sensing technologies in smart grid. However, as many of the communication technologies currently recommended to use by a smart grid is vulnerable in cyber security, it could lead to unreliable system operations, causing unnecessary expenditure, even consequential disaster to both utilities and consumers. In this paper, we summarize the cyber security requirements and the possible vulnerabilities in smart grid communications and survey the current solutions on cyber security for smart grid communications. © 2012 IEEE
