Journal of Advanced Computational Intelligence and Intelligent Informatics 10, no. 2 (March 20, 2006): 173–80. http://dx.doi.org/10.20965/jaciii.2006.p0173.
Full textAbstract:
Building an intelligent robot system has been an extensive research area. There are many advances in components needed to construct the robotic system, such as vision systems, sensory systems, planning systems, among others. Integration of this components represents a big challenge for robot designers, due to they come from different vendors and with different interfaces or operating systems. This is more difficult if the overall system development has to deal with environmental uncertainties or changing conditions. In these cases, new tools and equipment are necessary to adapt the initial configuration to the new changing requirements. Each added component increases the complexity of the system due to the interconnection required with the previous components. In this work, we present an approach to solve this integration problem using concepts of distributed computing areas. We named this concept Wrapper Components. This concept is based on a standard middleware software specification. Wrapper components are object-oriented modules that create an abstract interface for a specific class of hardware or software components. If these components provide “intelligent” functions, the overall system is capable of show some basic smart behavior through specific actions to react under changes in the environment. We tested our approach by solving an experimental classical problem named block-world. The intelligent functions are object recognition, environment recognition, planning, tracking capabilities and robot arm control.

Purpose This paper aims to describe the idea behind and design of a miniaturized distributed measurement system based on a controller area network (CAN) data bus. Design/methodology/approach The intention of the designers was to build a light and modular measurement system which can be used in remotely piloted aircraft systems and ultra-light aircraft during flight tests, as well as normal operation. The structure of this distributed measurement system is based on a CAN data bus. The CAN aerospace standard has been applied to the software as well as the hardware comprising this system. PRP-W2 software designed for PCs is an additional component of the proposed measurement system. This software supports data acquisition from a recorder unit and allows for preliminary data analysis, as well as data conversion and presentation. Findings The system, complete with a high-speed data recorder, was successfully installed on board of an MP-02 Czajka aircraft. A research experiment using the system and oriented on airframe high frequency vibration analysis is presented in the final part of this paper. Research limitations/implications This measurement system allows analysis of high-frequency vibrations occurring at selected points of the aircraft. A data set is recorded by three-axis accelerometers and gyroscopes at frequencies up to 1 kHz. Practical implications The use of a miniature and lightweight modular measurement system will, in many cases, be faster and less expensive than full-scale measurement and data acquisition systems, which often require a lengthy assembly process. The implementation of this class of lightweight flight test systems has many advantages, in particular to the operation of small aircraft. Such solutions are likely to become increasingly common in unmanned aerial vehicles and in other light aircraft in the future. Originality/value The adaptation of a distributed measuring system with a high frequency of measurements for purposes of small and miniature aircraft.

Full textAbstract:
This paper proposed a new method of automated eliminating bubbles based on vision sense technology because detection and elimination of bubbles of injection materials is key factor which influences the quality of products and hinders realization of full automatic control for the vacuum casting. This method uses vision sensor to replace artificial visual measurement, and adopts processing of the bubbles images to judge the effect of eliminating bubbles instead of experiences of operators. This paper developed a bubbles monitoring control system to realize the automated eliminating bubbles method. The system adopts two-level distributed structure which is consisted of host and slave computers. The slave computer is composed of image acquisition module, controller module and execution module. It is responsible for controlling operation devices to finish vacuum casting. The host computer is responsible for supervisory control which includes human-machine interface module, camera control module and images analysis and processing module. The function of every module is described in detail. The operator is just needed to set relative parameters, and then the system will implement automatically. In a word, the controlling system based on this new method possesses some advantages such as high precision, efficiency and flexibility.

The article looks at the means of forming the research skills of students of pedagogical universities. Considerable attention is paid to the formation of students' creative thinking in the process of solving problems with parameters. A large number of applied problems, economic, physical, chemical, biological, technical, medical, etc., involve solving problems with parameters (within the framework of the constructed mathematical model). Tasks with parameters require more general research than ordinary equations, inequalities and their systems. In the article, solving problems with parameters is accompanied by graphical visualization followed by the use of the analytical method. CAS Maxima is used for graphical visualization (animation). The choice of tasks with parameters is due to the fact that mathematical, logical thinking and the ability to analyze, compare, synthesize, develop research skills evolve in the course of their solution. All this should lead to the search and introduction of new forms of pedagogy and technologies in education. The main component of the methodology here is computer-oriented, namely the use of a computer mathematics system. Using systems of computer mathematics, the student can improve the programming technique and ability to focus on the analysis of methods, immerse in the features of such concepts as the conditionality of the problem, the stability of the method, evaluation of the results of calculations. In this paper, we used the CAS Maxima animation tools with the wxMaxima graphical shell to investigate the problems with the parameters. The choice of the Maxima system is due to the following reasons: it is a freely distributed system, distributed under the GNU/GPL license; there are implementations under various operating systems, including Windows, Linux, MacOS; it offers intuitive interface and is easy and reliable in operation. The results of the study show that training of modern specialists, the development of their professional potential can only be effective provided that students are involved in research activities throughout their course of study.

SUMMARYThe paper presents an educational system for teaching and research in robotics which consists of a manipulator, controller and a PC compatible host computer. The advanced design of host-computer user-interface software makes the system very suitable for teaching. It allows the user not only to follow the system states but also to change the control structure on-line. In the first part of this paper the architecture of the system, window-oriented user interface, specially designed robot language and several build-in students lessons will be described as well as the data acquisition system and advanced graphical capabilities.In the second part of this paper the executive controller architecture is described. Besides the manipulator control function and IO operations, the controller supports communication with the host-computer. The controller is programmable, i.e. it executes various tasks within user-defined and build-in students lessons. By the use of simple host-computer commands the controller can execute various algorithms both for trajectory generation and dynamically compensated digital servo control. The dynamic model components in the feed-forward and feed-back control loop can be selectively included and changed during the manipulator's motion. Experimental results with a 4-link educational robot are presented.

Full textAbstract:
The Virtual Environment Operating Shell (veos) was developed at University of Washington's Human Interface Technology Laboratory as software infrastructure for the lab's research in virtual environments. veos was designed from scratch to provide a comprehensive and unified management facility to support generation of, interaction with, and maintenance of virtual environments. VEOS emphasizes rapid prototyping, heterogeneous distributed computing, and portability. We discuss the design, philosophy and implementation of veos in depth. Within the Kernel, the shared database transformations are pattern-directed, communications are asynchronous, and the programmer's interface is LISP. An entity-based metaphor extends object-oriented programming to systems-oriented programming. Entities provide first-class environments and biological programming constructs such as perceive, react, and persist. The organization, structure, and programming of entities are discussed in detail. The article concludes with a description of the applications that have contributed to the iterative refinement of the VEOS software.

Full textAbstract:
To support all phases of an agile modular manufacturing machine life cycle with CAE and Virtual Manufacturing tools, a number of different engineering applications (e.g. specialist software based tools) are typically used for design, simulation, analysis, programming, control and monitoring of a machine. These applications mainly exist today as small applications islands where each of them manages their own data. When a manufacturing machine is designed, simulated, programmed, analyzed, tested, or operated, the information, connected to that specific machine, used and generated by each application island is stored separately by each application. These application islands often use different storage technologies. Each one of the applications has an information structure to separate the information connected to each machine; however, they do not necessarily use the same information structure. Another issue concerning these applications is the functionality that is implemented in them to manage information; namely, processes such as store, retrieve, search, permissions, etc. The functionality for one process is the same in all applications that has the process implemented. But the implementation of the process functionality may differ, due to misinterpretation of the functionality specification and regular implementation bugs, which could lead to problem with integrity and consistency of the data. Applications that make use of newer information technologies, such as databases and software development tools can simplify the implementation of the functionality but each application still has to implement their own version of the functionality. This paper presents a research investigation focused on the development of a distributed integration platform that supports the whole life cycle of agile modular machine systems, which includes the design, simulation, programming, analysis, machine operation and re-configuration. The environment supports distributed management and storage of information in a system-wide library, information management and storage that is machine oriented, not application oriented, and information storage structured as reusable components to enable reuse of information and know-how that is produced throughout the life cycle of machines.

This paper proposes a vision-based embedded motion control system that is developed in our research group. The system is an integration of three subsystems including, an embedded positioning platform, a vision system for inspection and a crystal reorientation system. The system is used as a positioning platform and crystal reorientation system to automate the crystal reorientation process. This process is important in ensuring that the units are correctly oriented for production processes. The focus of this research is placed on how to develop the embedded positioning platform, the crystal reorientation system, and how to improve the system performances including positioning and reorientation accuracy in high speed operation and quality of inspection. A distributed control architecture has been developed using PIC18F4520 microcontrollers. Tests run on the complete system have shown that the system is capable of a minimum indexing time of 1.53 units per second and a reorientation time of 1.42 seconds.

The access control is a mechanism that a system grants, revoke the right to access the object. The subject and object can able to integrate, synchronize, communicate and optimize through read, write and execute over a UFS. The access control mechanism is the process of mediating each and every request to system resources, application and data maintained by a operating system and determining whether the request should be approve, created, granted or denied as per top management policy. The AC mechanism, management and decision is enforced by implementing regulations established by a security policy. The management has to investigate the basic concepts behind access control design and enforcement, point out different security requirements that may need to be taken into consideration. The authors have to formulate and implement several ACM on normalizing and optimizing them step by step, that have been highlighted in proposed model for development and production purpose. This research paper contributes to the development of an optimization model that aims and objective to determine the optimal cost, time and maximize the quality of services to be invested into security model and mechanisms deciding on the measure components of UFS. This model has to apply to ACM utilities over a Web portal server on object oriented and distributed environment. This ACM will be resolve the uncertainty, un-order, un formal and unset up (U^4) problems of web portal on right time and right place of any where & any time in around the globe. It will be more measurable and accountable for performance, fault tolerance, throughput, bench marking and risk assessment on any application.

The current way of designing industrial plants relies on the communication among experts in the field, and on tools that allow the simulation of the site. Virtual reality (VR) tools are used to visualize and interact with complex 3D environments in real time, and several engineering simulations employ VR to foresee the results of complex industrial operations. The research project described here presents a Service Oriented Architecture aimed to create a collaborative environment, called CEE (Collaborative Engineering Environment) that integrates VR techniques into a system where the execution of different sequences of engineering simulations is modeled as scientific workflows. The focus of this research is on the oil and gas industry, particularly offshore engineering, where the project of a new production unit is a lengthy, expensive and usually is conducted by different specialists who are geographically distributed. Among the integrated engineering simulations are those involving structural calculus, hydrodynamics, naval engineering with mooring systems, meteo-oceanography, and others. The main objective is to improve the users' interpretation capacity and skills while providing visualization tools for a better understanding of the results.

Full textAbstract:
System Wide Information Management(SWIM), as envisioned by theSingle European Sky Air Traffic Management Research(SESAR) program, is the application of service oriented architectures to the air traffic management domain. Service oriented architectures are widely deployed in business and finance but usually tied to one specific technological implementation. SWIM goes one step further by defining only the semantic layer of the application integration and leaving the implementation of the communication layer open to the implementer. The shift from legacy communication patterns to SWIM is fundamental for the expected evolution of air traffic management in the next decades. However, the air traffic management simulators currently in use do not reflect this yet. SWIM compliance is defined by semantic compatibility to theAir Traffic Management Information Reference Model(AIRM) and a SWIM service may implement one or more communication profiles, which specify a communication layer implementation. This work proposes a SWIM-compliant communication profile suitable to integrate SWIM-compliant tools into human-in-the-loop simulations for air traffic management research. We achieve this objective by implementing a SWIM communication profile using XML-based multicast messaging and extending the message format to support distributed human-in-the-loop simulations. We demonstrate our method by the evaluation of Hamburg Airport operations.

It is known that mobile robot applications have a preponderant role in industrial and social environments and, more specifically, helping human beings in carrying out difficult tasks in hostile environments. From teleoperated systems to autonomous robots, there is a wide variety of possibilities requiring a high technological level. Many concepts such as perception, manipulator design, grasping, dynamic control, etc. are involved in the field of industrial mobile robots. In this context, human–robot interaction is one of the most widely studied topics over the last few years together with computer vision techniques and virtual reality tools. In all these technical fields, a common goal is pursued, i.e., robots to come closer to human skills. In this paper, first some important research projects and contributions on mobile robots in industrial environments are overviewed. Second, a proposal for classification of mobile robot architectures is described. Third, results achieved in two specific application areas of mobile robotics are reported. The first is related to the tele-operation of a mobile robot called ROGER by means of a TCP/IP network. The control system of the robot is built up as a distributed system, using distributed object oriented software, CORBA compatible. The second is related to the teleoperation of an underwater robot called GARBI. (Research project co-ordinated with the Polytechnic University of Catalonia (Prof. Josep Amat) and financed by the Spanish Government.) The utility of this kind of prototype is demonstrated in tasks such as welding applications in underwater environments, inspection of dammed walls, etc. Finally, an industrial project involving the use of intelligent autonomous robots is presented showing how the experience gained in robotics has been applied.

Due to the fast pace of computer instrumentation and technology, we are quickly approaching an age where on-line use of expensive research facilities will become commonplace. The consequences of this trend will be multifaceted. It will allow scientist and researchers to perform experiments and access data with greater ease without the burden some overhead associated with working onsite. It will allow for the on-line storage and analysis of data. And lastly, an ideal testbed will be provided for integrating intelligent man-machine interfaces in order to reduce labor intensive tasks. This will simplify the control of complicated instruments via automation of the controls whose human control is not essential. Unfortunately, attempts at building a common platform for remote operation will face several problems. First of all, a successful general purpose architecture will frequently need to be extended in order to perform new functions as well as utilize new hardware. Similarly, the continued development of new microscopes, stage controls, etc. will undoubtedly create incompatible interfaces which will break presently working systems. Lastly, the environment that such a system will operate will likely be characterized by heterogeneous hardware and software. Based on the experience of building on-line systems for use of optical and electron microscopes, we propose a scalable system architecture based on the principles of object oriented design and analysis, a machine independent user- interface based on Java, and a software bus that supports distributed objects over the network.

Full textAbstract:
An operator-controlled crack-sealing machine was developed and tested at the Advanced Highway Maintenance and Construction Technology (AHMCT) Research Center at the University of California, Davis. The machine, integrated onto a single truck, provides ease of operation and a simple, automated method of sealing random pavement cracks. The operator provides the machine its tasks and is the decision maker; the machine automatically performs the repetitive and dangerous tasks of mapping pavement cracks, creating seal paths for the robot, and sealing the cracks. The operator communicates with the machine through a simple user interface adjacent to the driver. This operator control approach drastically reduces the machine’s control complexity relative to fully automated crack-sealing machines. To be able to seal cracks within a full lane without intruding into adjacent lanes, a telescoping long-reach robotic arm was developed that can position the sealing head mounted to its end in a large 3.7- x 4-m (12- x 13-ft) workspace, within 0.4 mm (1/64 in.) at a traverse speed up to 1 m/s (3 ft/s). A special sealant applicator that deploys a pressurized reservoir was developed to allow high-speed and automated sealing operations. A 100-Mbps fast Ethernet and 10-Mbps wireless control network allows for distributed real-time motion control, input/output control, and machine vision. A fully object-oriented, multithreaded Internet-based software architecture allows reliable and efficient system integration and provides an interactive and responsive user interface for feature-rich and easy imaging, path planning, and system control.

The process of testing weapons and military equipment involves numerous manual labor-intensive operations. Such operations can be simplified by fully or partially automating the test planning stages, conducting them directly, and processing the test results. Feature of testing weapons and military equipment is the large amount of data that somehow has a spatial location. One of the modern tools of cartographic representation, processing and analysis of statistical data arrays that have spatial localization, geospatial modeling and situation forecasting is the technology of geoinformation systems.
The article substantiates the feasibility of using geoinformation systems as part of the weapons testing system and military equipment. The functional scheme of integration of the geoinformation component into the structure of the test automation subsystem is presented for geoinformation support of the processes of testing planning and processing of measurement results. An approach to the creation of geoinformation models of test sites is proposed, based on the use of methods of remote sensing of land and open Web-GIS resources. The list of functional modules of spatial data processing and analysis, which can be applied to the tasks of testing, is distributed in the geoinformation toolkit. Examples of typical spatial tasks that can be performed during test planning, direct testing, processing, and analysis of measurement results, if such data are spatially linked.
The use of geoinformation technology in the test system will provide an arsenal of qualitatively new methods of digital cartography, such as the technology of automated preparation of cartographic information in the accepted cartographic projections and symbols, mass processing of arrays of measured data, a wide toolkit of mathematical and cartographic methods and functions, features and functions own methods, algorithms and methods of statistical information processing, create and use object-oriented geoinformation data models, operate with a set of visualization tools for the best presentation of research and simulation results.

The intensive development of information and control technologies, as well as their integration into a single information space, leads to an increase in the role of such technologies in the processes of control of troops (forces) and weapons, including high-precision ones. At the same time, the electronic material base of the information infrastructure created within the concept of network-centric warfare is potentially vulnerable to electronic warfare.
In this article, the authors analyze the approaches to the impact of electronic warfare on network-centric control systems. In the course of the study, the authors solved the following interrelated tasks: identified information restrictions on the implementation of the network-centric war concept; the prospects for the development of electronic warfare systems that are focused on disruption of the operation of network-centric systems of military control and the prospective scientific and methodological approaches to substantiate the methods of radio-electronic impact on network-centric control systems.
In the course of this research, the authors used the basic principles of electronic warfare theory, signal theory, communication theory, queuing systems and classical methods of scientific cognition – analysis and synthesis. According to the results of the study, the following conclusions can be drawn: perspective directions for the development of radio-electronic impact, oriented on the transport layer of communication networks, can be implemented as complexes of territorially distributed means of electronic control, implementing fundamentally new methods of suppression, and special software and bookmarks software (viruses) that are introduced into the telecommunications network equipment.
It should be noted that the use of all the above radio-electronic effects is advisable only against packet networks with advanced topology. The use of such impacts against networks with tree topology is pointless since there is a possibility of attaining the suppression effect by“classical” channel suppression.

Due to the growth of users and linked devices in networks, there is an emerging need for dynamic solutions to control and manage computing and network resources. This document proposes a Distributed Wireless Operative System on a Mobile Ad-hoc Network (MANET) to manage and control computing resources in relation to several virtual resources linked in a wireless network. This prototype has two elements: a local agent that works on each physical node to manage the computing resources (e.g., virtual resources and distributed applications) and an orchestrator agent that monitors, manages, and deploys policies on each physical node. These elements arrange the local and global computing resources to provide a quality service to the users of the Ad-hoc cluster. The proposed S.O.V.O.R.A. model (Operating Virtualized System oriented to Ad-hoc networks) defines primitives, commands, virtual structures, and modules to operate as a distributed wireless operating system.

Full textAbstract:
This book analyses the evolution of the tax system and economic development in Taiwan over four decades, and argues that three crucial factors – prudent public sector expenditure, an effective revenue system and a set of export-oriented trade policies – contributed to the achievement of macroeconomic stability and growth in Taiwan from 1955 to 1995. It is divided into seven broad themes: evolution of the tax system; various stages of Taiwan's economic development; assessment of tax incentive policies in relation to investment, savings and economic growth; the evolution of Taiwan's trade policies; the correlation between tax policies and other macroeconomic variables; innovation and pragmatism in the inland tax administration; and the management of transaction costs with respect to the trade administration.The authors argue that like many other countries, Taiwan experienced hyperinflation and fiscal crisis after the Second World War. In order to solve the difficulties, instead of relying on foreign borrowing or using domestic private savings to finance itself, the Taiwanese government effectively limited public spending, which not only pushed inflation rates down but also created a stable macroeconomic environment. In addition, the operation of the tax system played a significant role in promoting economic development. For instance, instead of emphasizing the importance of income tax as a main tool for raising revenues, the government introduced state-run monopolies in alcoholic beverages and tobacco in 1950 and enforced the value-added tax system in 1986, providing a solid foundation for the revenue system. The authors find trade and macroeconomic policies, rather than income tax policies or subsidized finance measures, to be the main determinants in successful industrialization.

The intensive development of information and control technologies, as well as their integration into a single information space, leads to an increase in the role of such technologies in the processes of control of troops (forces) and weapons, including high-precision ones. At the same time, the electronic material base of the information infrastructure created within the concept of network-centric warfare is potentially vulnerable to electronic warfare. In this article, the authors analyze the approaches to the influence of electronic warfare on network-centric control systems. In the course of the study, the authors solved the following interrelated tasks: identified information restrictions on the implementation of the network-centric war concept; the prospects for the development of electronic warfare systems that are focused on disruption of the operation of network-centric systems of military control and the prospective scientific and methodological approaches to substantiate the methods of radio-electronic influence on network-centric control systems. In the course of this research, the authors used the basic principles of electronic warfare theory, signal theory, communication theory, queuing systems and classical methods of scientific cognition - analysis and synthesis. According to the results of the study, the following conclusions can be drawn: perspective directions for the development of radio-electronic influences, oriented on the transport layer of communication networks, can be implemented as complexes of territorially distributed means of electronic control, implementing fundamentally new methods of suppression, and special software and bookmarks software (viruses) that are introduced into the telecommunications network equipment. It should be noted that the use of all the above radio-electronic effects is advisable only against packet networks with advanced topology. The use of such influences against networks with tree topology is pointless given the possibility of attaining the suppression effect of “classical” channel suppression

This paper presents advances in the development of specialized mobile applications for combat decision support utilizing augmented reality technologies used for the production of contextual data delivered to any tactical smartphone. Handhelds and decision support systems have been present in military operations since the 1990s. Due to the development of hardware and software platforms, smartphones are capable of running complex algorithms for individual soldiers and low-level commander support. The utilization of tactical data (force location, composition, and tasks) in dynamic mobile networks that are accessible anywhere during a mission provides means for the development of situational awareness and decision superiority. These two elements are key factors in 21st-century military operations, as they influence the efficiency of recognition, identification, and targeting. Combat support tools and their analytical capabilities can serve as recon data hubs, but most of all they can support and simplify complex analytical tasks for commanders. These tasks mainly include topographical and tactical orientation within the battlespace. This paper documents the ideas for and construction details of mobile support tools used for supporting the specific operational activities of military personnel during combat and crisis management. The presented augmented reality-based evaluation methods formulate new capabilities for the visualization and identification of military threats, mission planning characteristics, tasks, and checkpoints, which help individuals to orientate within their current situation. The developed software platform, mobile common operational picture (mCOP), demonstrates all research findings and delivers a personalized combat-oriented distributed mobile system, supporting blue-force tracking capabilities and reconnaissance data fusion as well as threat-level evaluations for military and crisis management scenarios. The mission data are further fused with Geographic Information System (GIS) topographical and vector data, supporting terrain evaluations for mission planning and execution. The application implements algorithms for path finding, movement task scheduling, assistance, and analysis, as well as military potential evaluation, threat-level estimation, and location tracking. The features of the mCOP mobile application were designed and organized as mission-critical functions. The presented research demonstrates and proves the usefulness of deploying mobile applications for combat support, situation awareness development, and the delivery of augmented reality-based threat-level analytical data to extend the capabilities and properties of software tools applied for supporting military and border protection operations.

Real-time (RT) object-oriented (OO) distributed computing is a form of RT distributed computing realized with a distributed computer system structured in the form of an object network. Several approaches proposed in recent years for extending the conventional object structuring scheme to suit RT applications, are briefly reviewed. Then the approach to RT OO distributed computing which the author and his collaborators have been establishing in recent years will be reviewed in more detail. The approach named the TMO (Time-triggered Message-triggered Object) structuring scheme was formulated with the goal of instigating a quantum productivity jump in the design of complex real-time computing systems (RTCS's). The TMO scheme is intended to facilitate the pursuit of a new paradigm in designing RTCS's which is to realize real-time computing with a common and general design style that does not alienate the main-stream computing industry and yet to allow system engineers to confidently produce certifiable RTCS's for safety-critical applications. The TMO structuring scheme is a syntactically simple but semantically powerful extension of the conventional object structuring approaches and as such, its support tools can be based on various well-established OO programming languages such as C++ and JAVA and on ubiquitous commercial RT operating system kernels. The scheme enables a great reduction of the designer's efforts in guaranteeing timely service capabilities of application systems. Also, the scheme is applicable to structuring of not only complex distributed RTCS's but also application environment descriptors/simulators and requirement specifications.

Particle physics experiments rely extensively on computing and data services, making e-infrastructure an integral part of the research collaboration. Constructing and operating distributed computing can however be challenging for a smaller-scale collaboration. The Light Dark Matter eXperiment (LDMX) is a planned small-scale accelerator-based experiment to search for dark matter in the sub-GeV mass region. Finalizing the design of the detector relies on Monte-Carlo simulation of expected physics processes. A distributed computing pilot project was proposed to better utilize available resources at the collaborating institutes, and to improve scalability and reproducibility. This paper outlines the chosen lightweight distributed solution, presenting requirements, the component integration steps, and the experiences using a pilot system for tests with large-scale simulations. The system leverages existing technologies wherever possible, minimizing the need for software development, and deploys only non-intrusive components at the participating sites. The pilot proved that integrating existing components can dramatically reduce the effort needed to build and operate a distributed e-infrastructure, making it attainable even for smaller research collaborations.

Integration is the process of enabling a communication between disparate software components. Integration has been the burning issue for large enterprises in the last twenty years, due to the fact that 70% of the development and deployment budget is spent on integrating complex and heterogeneous back-end and front-end IT systems. The need to integrate existing applications is to support newer, faster, more accurate business processes and to provide meaningful, consistent management information. Historically, integration started with the introduction of point-to-point approaches evolving into simpler hub-and spoke topologies. These topologies were combined with custom remote procedure calls, distributed object technologies and message-oriented middleware (MOM), continued with enterprise application integration (EAI) and used an application server as a primary vehicle for integration. The current phase of the evolution is service-oriented architecture (SOA) combined with an enterprise service bus (ESB). Technical aspects of the comparison between the aforementioned technologies are analyzed and presented. The result of the study is the recommended integration strategy for large enterprises.

XtreemOS is a distributed operating system for large-scale wide-area dynamic infrastructures spanning multiple administrative domains. XtreemOS, which is based on the Linux operating system, has been designed as a Grid operating system providing native support for virtual organizations. In this paper, we discuss the positioning of XtreemOS technologies with regard to cloud computing. More specifically, we investigate a scenario where XtreemOS could help users take full advantage of clouds in a global environment including their own resources and cloud resources. We also discuss how the XtreemOS system could be used by cloud service providers to manage their underlying infrastructure.
