Lake monitoring surveys data are vital and have been being accumulated for every lake. However data itself, without effective data management and interpretation, cannot be used to tell the story or history of the lake. Therefore, this project aims to develop a new water quality database system for a lake with systematical functions to utilize such data effectively and to satisfy both general public users and specialists. Lake Biwa was chosen as the target lake, where long-term monitoring data were available for almost one hundred years. A relational database application, Access 2002, with the help of Macro functions and VBA (Visual Basic for Applications) was introduced to organize all of the data. With the systematical storing of data, valuable data could be easily accessed, filtered and powerfully utilized for researchers own interests. The filtered data can be written into basic documents (spreadsheet or text files), provided for outside requests, and again used for further basic and advanced analysis by a reading back process. The system supports multiple users, especially public users by providing user interface system and visualized result displays. The final outcomes from this systematic data utilization can be fruitfully used as the guideline for effective monitoring management program of lake water quality.

The project DEMETER (DEMonstration of Earth observation TEchnologies in Routine irrigation advisory services) was designed to assess and demonstrate improvements introduced by Earth observation (EO) and Information and Communication Technologies (ICT) in farm and Irrigation Advisory Service (IAS) day-to-day operations. The DEMETER concept of near-real-time delivery of EO-based irrigation scheduling information to IAS and farmers has proven to be valid. The operationality of the space segment was demonstrated in three different pilot zones in South Europe during the 2005 irrigation campaigns. Extra-fast image delivery and quality controlled operational processing make the EO-based crop coefficient maps available at the same speed and quality as ground-based data (point samples), while significantly extending the spatial coverage and reducing service cost. The new online Space-Assisted Irrigation Advisory Service (e-SAIAS) is the central outcome of the project. Its key feature is the operational generation of irrigation scheduling information products from a virtual constellation of high-resolution EO satellites and their delivery to farmers in near-real-time using leading-edge on-line analysis and visualization tools. First feedback of users at IAS and farmer level is encouraging. The paper gives an overview of the project and its main achievements.

SPE Annual Technical conference and Exhibition, ATCE 2006: Focus on the Future

The north Texas Barnett shale illustrates successful commercialization of an unconventional reservoir. However, it took 17 years to evolve from pumping crosslinked gel (XLG) carrying more than 1 million pounds of proppant per job to slick water fracs (SWF) consisting of large volumes of water and small quantities of sand. This transition to SWF stimulation opened the door for widespread development that has advanced the Newark East (Barnett shale) to the largest producing gas field in the state of Texas. This paper investigates Barnett completion strategy during the time period from 1993-2002. The 393-well dataset includes completion, reservoir, and production data Unique data visualization tools were used to investigate various completion parameters and their effect on production.1 This unbiased look at a large block of data challenges some of the preconceived opinions about Barnett shale, including: The Barnett shale is a continuous/homogeneous formation yielding commercial production in all instances. XLG fracture stimulation is damaging to the Barnett, and SWF always outperform XLG fracs. High rates and large volumes of fluid and proppant always give higher production. Reservoir quality is unimportant or has a negligible effect on production outcome. The effect of changes in stimulation variables on production is readily *** found that production results show a broad scattering when crossplotted with various completion and reservoir inputs. This result is not uncommon when analyzing field data. The large number of variables and scatter within the data required the use of data clustering techniques to extract useful information. Advanced data mining techniques were used, including self-organizing maps (SOM) to reduce the statistical noise and highlight completion and reservoir parameters directly affecting production. The results show a production outcome based on reservoir quality and completion strategy. Copyright 2006, Society of Petroleum Engineers.

IEEE International conference on Fuzzy Systems (FUZZ-IEEE)

作者： N.J. van Eck L. Waltman J. van den Berg U. Kaymak Faculty of Economics Erasmus University Rotterdam Rotterdam Netherlands

In this paper, a knowledge domain visualization approach is applied to the computational intelligence held. A so-called concept map based on the abstracts of the papers presented at the WCCI 2006 is constructed and analyzed. The concept map provides an overview of the computational intelligence field by visualizing the associations between the field's main concepts. To analyze recent developments in the computational intelligence field, the concept map is compared with a concept map based on abstracts of the WCCI 2002. The analysis presented in the paper provides insight into the structure of the computational intelligence field and into the most significant developments in the field during the last years.

King Research Report BBKCS, School of Computer Science and Information Systems, Birbeck College, University of London, 2002 Traditionally most of the literature in social network analysis (SNA) has focused on networks of individuals. Although SNA is not conventionally considered as a data mining technique, it is especially suitable for mining a large volume of association data to discover hidden structural patterns in terrorist networks. After September 11 attacks, SNA has increasingly been used to study terrorist networks. As these covert networks share some features with conventional networks, they are harder to identify because they mask their transactions. The most complicating factor is that terrorist networks are often embedded in a much larger population (i.e., adversaries have links with both covert and innocent individuals). Hence, it is desirable to have tools to correctly classify individuals in covert networks so that the res

One of the challenges of visualization software design is providing real-time tools capable of concurrently displaying data that varies temporally and in scale from kilometers to micrometers, such as the data prevalent in planetary exploration and deep-sea marine research. The Viz software developed by NASA Ames and the additions of the X-Core extensions solve this problem by providing a flexible framework for rapidly developing visualization software capable of accessing and displaying large dynamic data sets. This paper describes the Viz/X-Core design and illustrates the operation of both systems over a number of deployments ranging from marine research to Martian exploration. Highlights include a 2002 integration with live ship operations and the Mars Exploration Rovers Spirit and Opportunity.

This paper introduces a set of visualization tools that aim to support social navigation, the evaluation and optimization of three-dimensional virtual worlds and the study of their evolving communities. Previous work (Bomer Lin, 2001;Bomer et al., 2002) demonstrated how this toolset can be used to analyze data acquired during a information treasure hunt. This paper extends and applies this tool set to visualize an entire virtual conference on the topic Virtual Learning in Three Dimensions (VLearn3D)) that was held in December 2002.

H-MDS: a new approach for interactive visualization with multidimensional scaling in the hyperbolic space

INFORMATION SYSTEMS 2004年第4期29卷 273-292页

We introduce a novel projection-based visualization method for high-dimensional data sets by combining concepts from MDS and the geometry of the hyperbolic spaces. This approach hyperbolic multi-dimensional scaling (H-MDS) is a synthesis of two important concepts for explorative data analysis and visualization: (i) multi-dimensional scaling uses proximity or pair distance data to generate a low-dimensional, spatial presentation of the data;(ii) previous work on the "hyperbolic tree browser" demonstrated the extraordinary advantages for an interactive display of graph-like data in the two-dimensional hyperbolic space (H-2). In the new approach, H-MDS maps proximity data directly into the H-2 This removes the restriction to "quasi-hierarchical", graph-based data-a major limitation of (ii). Since a suitable distance function can convert all kinds of data to proximity (or distance-based) data, this type of data can be considered the most general. We review important properties of the hyperbolic space and, in particular, the circular Poincare model of the H-2. It enables effective human-computer interaction: by mouse dragging the "focus", the user can navigate in the data without loosing the context. In H-2 the "fish-eye" behavior originates not simply by a non-linear view transformation but rather by extraordinary, non-Euclidean properties of the H-2. Especially, the exponential growth of length and area of the underlying space makes the H-2 a prime target for mapping hierarchical and (now also) high-dimensional data. Several high-dimensional mapping examples including synthetic and real-world data are presented. Since high-dimensional data produce "ring"-shaped displays, we present methods to enhance the display by modulating the dissimilarity contrast. This is demonstrated for an application for unstructured text: i.e., by using multiple film critiques from news:*** and ***, each movie is placed within the H-2-creating a "space of movies" f

Terrorism information awareness (TIA) was initiated by the Information Awareness Office (IAO) of the Defense Advanced Research Projects Agency (DARPA) (Snowden and Kurtz, 2002; 2003; Snowden, 2000). TIA capabilities enable the detection, classification, identification, and tracking of terrorist activities in order to provide early warning of plans and to identify options to prevent them from being executed. TIA operated as a research program in an environment with real data, real users, and real missions. This environment presented many challenges to the collection and analysis of metrics. Like most large things, the TIA program was a mixture of the "complicated" and the "complex". At a high level, the program could be considered as both a "system" and a human "network". The "system" is complicated, able to be analyzed from its constituent components. On the other hand, the "network" is a complex composite of the activities of small groups engaged in problem solving. To analyze TIA experiments, we adopted multiple interwoven sets of "perspectives" encompassing both the system and the net. All perspectives were engaged simultaneously. The first set of three, which defined the make up of the Metrics Team, were a cognitive perspective, an operational perspective, and a technical perspective. We also established five "threads" of functional capability to study the technologies: structured discovery, link and group understanding, decision-making with corporate memory, collaborative problem solving, and context-aware visualization. Finally, we established models of the operational context (mission, goals, and resources) for each of the collaboration groups, called "scenarios". The metrics for these analyses were derived using an explicit model based on a UML metrics meta-model. Presenting aggregated analyses in a way that fosters understanding without losing the appreciation of the complexities of the program is itself a complex task. Stones have the ability to organize t
