Although high-speed/broadband telecommunication networks like B-ISDN may be necessary for the implementation of new types of services, the availability of such networks is not sufficient to ensure their success. Considerable research and development are still necessary to ensure that: (1) flexible tools are available to build distributed applications, (2) through experimentation with a range of new services, insight is gained into what is really useful, (3) attractive user interfaces are built, and (4) adequate activity/traffic models exist so that the new networks and their capabilities can be economically planned. It should be noted that many of the proposed research topics are not directly dependent on quantitative characteristics like resolution or bit rate. Rather, characteristics at the system level have to be investigated.< >

A valuable technique during concept development is rapid prototyping of software for key design components. This approach is particularly useful when the optimum design approach is not readily apparent or several known alternatives need to be rapidly evaluated. A problem inherent in rapid prototyping is the lack of a "target system" with which to interface. Some alternatives are to develop test driver libraries, integrate the prototype with an existing working simulator, or build one for the specific problem. This paper presents a unique approach to concept development using rapid prototyping for concept development and scenario-based simulation for concept verification. The rapid prototyping environment, derived from artificial intelligence technology, is based on a blackboard architecture. The rapid prototype simulation capability is provided through an object-oriented modeling environment. It is shown how both simulation and blackboard technologies are used collectively to rapidly gain insight into a tenacious problem. A specific example will be discussed where this approach was used to evolve the logic of a mission controller for an autonomous underwater vehicle.

Sunday:is a mathematician on the Principal Professional Staff of the Fleet Systems Department of The Johns Hopkins University Applied Physics Laboratory. He earned his Ph.D. in mathematics from the University of Minnesota in 1971 and did postdoctoral research on neural networks at the University of California at Berkeley.

He was the network designer for the Headquarters Integrated Office System (HIOS) Network for the Army at the Pentagon. He is currently the lead software engineer on the Command Support At-Sea Experiment Project.

The Command Support At-Sea Experiment (CS@SE) provides experimental advanced graphics display systems consisting of large screen color displays and operator console color displays in the combat information center (CIC) of an Aegis cruiser and in the tactical flag command center (TFCC) of an aircraft carrier. CS@SE systems are designed to prototype potential command support capabilities in an at-sea environment to validate and refine requirements for planned production system upgrades. These systems use sophisticated color graphics techniques to provide real-time tactical displays that improve the availability of information to an operator by reducing clutter through the use of color, area fill, transparen overlays and intensity coding of track symbols. Interfaces wen developed with the Aegis Display System (ADS), Shipboarc Gridlock System with Auto-correlation (SGS/AC), Flag Dats Display System (FDDS) and Tomahawk Engagement Planning and Exercise Evaluation System (TEPEE) that provided the data for the presentation of a tactical display. Display elements included both real-time and over-the-horizon (OTH) surface track data, velocity leaders, tags, uncertainty ellipses, and history trails. The display also included filled land masses, country boundaries, commercial airways, cities, graphics overlays (i.e., operational areas), weapon system missile performance contours, and engagement plans. This paper describes the experiment, its installation and integration into the shipboard environments of an Aegis cruiser (USS Leyte Gulf ) and an aircraft carrier (USS America , its usage by the ships companies and embarked staffs, and the experiment result! and findings. Key conclusions of the experiment are: 1 Advanced graphics color displays can significantly enhance the ability of the warfighter to assimilate a complex tactical display. 2 Both ships reported a requirement for a correlated OTH and real-time track display with the ability to clearly differentiate the two types

This paper provides some extensions of a powerful open-loop model reduction technique called balanced realization. Developed by Moore, this approach uses concepts of controllability and observability to determine a reduced-order model. Moore's work was developed for controllable, observable, and asymototically stable systems. This paper shows that balancing techniques can be easily extended to unstable systems. Furthermore, using another model reduction method, called chained aggregation, the balanced and chained aggregation methods can be easily combined for systems that are also unobservable and uncontrollable.

TESS: multivariate sensor time series prediction for building sustainable smart cities

引用

ACM Transactions on Sensor networks 1000年

作者： Le Sun Zhaoyi Zhong Chunjiong Zhang Yanchun Zhang Di Wu Engineering Research Center of Digital Forensics Ministry of Education Nanjing University of Information Science and Technology and Department of Jiangsu Collaborative Innovation Center of Atmospheric Environment and Equipment Technology (CICAEET) Nanjing University of Information Science and Technology China Department of Computer Science and Technology Tongji University China Department of New Networks Peng Cheng Laboratory Shenzhen China and Cyberspace Institute of Advanced Technology Guangzhou University China

Time series analysis can help build sustainable smart cities with high energy efficiency. Smart cities contain a large number of sensors. The sensor data are mostly complex time series, such as traffic, electricity, and gas emission data. Accurate time series prediction can greatly help reduce energy consumption and gas emission. It is difficult to make accurate time series prediction because there are complex correlations among time series and the data have local and global nonlinear dependencies. To overcome the difficulties, we first analyze state-of-the-art works of time series prediction. Then we propose a new framework for Time series prediction evaluation for Energy conServation and emission reduction in Smart cities, called TESS. TESS is used to compare the latest time series prediction models based on six publicly available datasets and three simulation datasets. Based on the theoretical analysis and the experiment result, we get some interesting ideas: time series in smart cities often have obvious periodicity and scale changes, and need to be collected over the long term; skip-connection is helpful for learning long-term features of time series; the recurrent layer is good at predicting time series with obvious periodicity; and linear regression may be more appropriate for predicting time series with scale changes.

This book constitutes the refereed proceedings of the 9th IFIP-TC6 Networking Conference, Networking 2010. Papers were solicited in three broad topic areas: applications and services, network technologies, and internet design. All papers were considered on their merits by a uni?ed Technical ProgramCommittee (TPC); there was no attempt to enforce a quota among topic areas. We believe the resulting program is an excellentrepresentationofthebreadthofrecentadvancesinnetworkingresearch. This year, the conference received 101 full paper submissions from 23 co- trieson?vecontinents,re?ectingastrongdiversityinthenetworkingcommunity. Similarly, the 92 members of the TPC are from 21 countries and include a mix of academic, industry, and governmental a?liations. The TPC members, aided by some 50 external reviewers, provided a total of 470 reviews and follow-up discussions totaling more than 200 messages. The ?nal selections were made at a TPC meeting hosted by Columbia University in New York City, with both in-person and remote participation. In total, authors of accepted papers have academic and industry a?liations in 15 countries. We ?nally selected 24papers for presentationduring the conference technical sessions. A small number of papers were assigned a shepherd from the TPC to assist in paper revision. These statistics represent an acceptance rate of just under 24%, comparable to that of previous years. The TPC also identi?ed several papers that re?ect particularly promising early results; these papers were selected for presentation as work-in-progress papers and are identi?ed as such in the proceedings.
