Modelling and simulation has become the third pillar of gaining knowledge. Modelling and simulation of a process makes use of a simulation software, and quality of results and investigation time depend dramatically on the choice of the most appropriate simulator. Consequently, a basis for simulator choice or at least serious hints are necessary. This contribution first gives an overview about methods for comparing and benchmarking simulation systems. Then it introduces the ARGESIM benchmarks/comparisons on simulation software and gives details on some comparisons. The paper concludes with an outlook for further development of the ARGESIM benchmarks

Interactive learning is becoming increasingly important in the modern educational system. Ideally students should be able to expand on their knowledge, assess their progress and receive feedback from a remote location, outside the classroom. This research presents a graphically-based methodology to model the semantic structure of textual exchanges in the form of question and answer (Q/A). A machine learning approach is then presented which classifies questions and answers based on the similarities of their semantic structures. Because the methodology is graphically-based, similarities between graphs can be identified to establish context-free relationships/ associations between answers, or between questions and possible answers. By these means the relevant textual exchanges can be systematically analyzed and classified

This paper outlines the idea and plan of developing an intelligent assistant for table tennis umpire in evaluating services. Table tennis is a fast sport. A service usually takes a few second to complete but there are many observations an umpire needs to take and makes a judgment before or soon after the service is complete. This is a complex task and the author believes the employment of videography, image processing and artificial intelligence (AI) technologies could help evaluating the service. The aim of this research is to develop an intelligent system which is able to track the location of the ball from live video images and evaluate the service according to the service rules. This is a pilot study and the focus is on the development of the techniques, rather than building a complete system. Various videography, image processing and artificial intelligence techniques will be experimented and evaluated. When a prototype system is built, it will be compared and tested against the judgments of a human umpire. Both the accuracy and rate of responses will be concerned. Furthermore, as well as aiding umpire, the system could also benefit players who want to have their services evaluated in real time without the need of having a human umpire present

This paper presents the development and evaluation of a model for mapping the quality of service (QoS) requirements and traffic characteristics of aggregated IP traffic flows belonging to multiple classes of continuous media (audio and video) sources onto a single ATM virtual channel (VC) that is also shared with a number of IP data classes. This model was developed as part of a wider range of research activity focused on supporting QoS in future IP networks. The model presented in this paper offers improvements on an earlier model that used an "idealized" scheduler and was validated only for homogeneous continuous media sources. The paper discusses the improved scheduling mechanism that can minimize the effects of imperfections in cell level scheduling and presents a simulation experiment to validate the new model for aggregated heterogeneous continuous media sources

Matching resources is a fundamental problem within large scale distributed environments such as Grid for which the critical process is resource discovery and description. An effective way of solving this problem is providing meta-data about the resources. Ontologies can be used to capture metadata information. Ontologies determine the terms of Grid entities, resources, capabilities and the relationships between them with meaning by the addition of ontological annotations. In this paper we present the initial design of resource description ontology. This ontology can be used for solving resource matching for Grid using semantic Web technologies

The main goal of this paper is to describe a new approach of the European Space Operations Centre (ESOC) in designing and executing simulations, during the ground segment operational validation, for the training of mission control teams responsible of the operations of European satellites. The new approach is based on the concept of long loop simulations: facilitating more realistic simulation scenarios by increasing the level of participation of the real ground stations in the simulation campaigns. Long loop simulations are achieved by connecting the real-time operational satellite simulator, located in ESOC, in the satellite mission control centre, to a portable satellite simulator (PSS) located at the ground station. The telemetry data, produced by the operational simulator, is fed into the PSS and then follows the same path of the real satellite telemetry, passing through all the ground station equipment. Similarly, telecommands are routed from the control centre to the ground station equipment and then via PSS to the operational simulator. Thus the entire operational chain is involved in the simulation. In addition long loop simulations will enable ESOC users to connect all end to end equipment for accurate and systematic validation of each individual system

Finite buffer queues under complex management schemes are of great importance towards effective congestion control and quality of service (QoS) provision in the telecommunication networks. This paper analyses a single server G/G/1/N censored queue with R (R ges 2) traffic classes under complete buffer partitioning scheme and first come first served (FCFS) service discipline. A finite capacity vector, N, represents the capacity of partitions for each class (N1, N2, ..., NR). The forms of the state probabilities, as well as basic performance measures such as blocking probability are analytically established at equilibrium via appropriate mean value constraints based on the principle of maximum entropy (ME). Typical numerical experiments are included to illustrate the credibility of the proposed analysis in the context of generalised exponential (GE)-type queues

This paper presents a novel distributed modeling and simulation framework, which is designed and implemented to cater for a wide variety of scenarios and applications including situations spread over large complex distributed networks. The major contribution is in developing an infrastructure that can provide numerous services like time management, data distribution management, entity management, context aware management, ownership management etc. to distributed simulation. This is accomplished by constituting a middleware over an HLA compliant RTI. This context-aware middleware is incorporated inside the runtime infrastructure to enhance the service defined in IEEE standard for distributed modeling and simulation. In many real world simulations context providers (sensors) can play a vital role. Using the framework different kinds of context providers can be added in a simulation

Steganography is defined as the art and science of hiding information, which is a process that involves hiding a message in an appropriate carrier for example an image file. The carrier can then be sent to a receiver without anyone else knowing that it contains a hidden message. In this paper we present a novel scheme to send message imperceptibly between points over Internet. This scheme uses fourth-order Chebyshev chaotic system to generate chaos sequence which is used to encrypt secret message, and then embeds the modulated message into identification field of IP header. Compared with Ahsa's scheme, this scheme can provide higher security. Furthermore, this schema allows sending covert message point to point by selecting proper IP packets according to path MTU discovery
