Classification models for the prediction of clinicians' information needs
Authors: Guilherme Del Fiol, Peter J. Haug
Venue: Journal of Biomedical Informatics (2009)

Objective: Clinicians face numerous information needs during patient care activities and most of these needs are not met. Infobuttons are information retrieval tools that help clinicians to fulfill their information needs by providing links to on-line health information resources from within an electronic medical record (EMR) system. The aim of this study was to produce classification models based on medication infobutton usage data to predict the medication-related content topics (e.g., dose, adverse effects, drug interactions, patient education) that a clinician is most likely to choose while entering medication orders in a particular clinical context. Design: We prepared a dataset with 3078 infobutton sessions and 26 attributes describing characteristics of the user, the medication, and the patient. In these sessions, users selected one out of eight content topics. Automatic attribute selection methods were then applied to the dataset to eliminate redundant and useless attributes. The reduced dataset was used to produce nine classification models from a set of state-of-the-art machine learning algorithms. Finally, the performance of the models was measured and compared. Measurements: Area under the ROC curve (AUC) and agreement (kappa) between the content topics predicted by the models and those chosen by clinicians in each infobutton session. Results: The performance of the models ranged from 0.49 to 0.56 (kappa). The AUC of the best model ranged from 0.73 to 0.99. The best performance was achieved when predicting choice of the adult dose, pediatric dose, patient education, and pregnancy category content topics. Conclusion: The results suggest that classification models based on infobutton usage data are a promising method for the prediction of content topics that a clinician would choose to answer patient care questions while using an EMR system.
Multiscale Design and Modeling of Protein-based Nanomechanisms for Nanorobotics
Authors: Mustapha Hamdi, Antoine Ferreira
Venue: International Journal of Robotics Research (2009)

In this paper, we present a novel approach that makes use of multiscale and multiphysics modeling coupled to virtual reality for nanorobotic prototyping systems. First, a CAD-assisted assembly system that integrates principles for a multiscale approach into a nanorobotics structure design is presented. Then, we focus on the different design levels, more specifically, the optimization of geometry structure carried out by quantum mechanics, molecular dynamics and continuum mechanics methodologies. As an illustration of the proposed multiscale modeling concepts, we test the dynamic characteristics of a molecular sarcomere mechanism through steered molecular dynamics (SMD) simulations. The nano-kinematic parallel platform is composed of protein-based passive kinematic chains and actuated by myosin actuators. Multiscale simulations and experiments prove the effectiveness and accuracy of the proposed design and modeling approaches.
An object-oriented programming approach for a GIS data-driven simulation model of traffic on an inland waterway
Authors: Daniel Sasso, William E. Biles
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

This research proposes the integration of a Geographic Information System (GIS) with the Arena Simulation software to model the transit of ocean-going vessels through the Panama Canal. The purpose of this integration is to initialize the simulation model with the vessels that are currently transiting the system and the ones ready to begin their transit taking into account waiting time in queue, booking status, navigation restrictions and their times through the locks. The interface process consists of gathering vessel location and attribute data, which is loaded in database format in the GIS where it is analyzed and displayed in a map containing the location of the locks, anchorage areas, tie-up stations and the transit route. Once analyzed, Arena reads the GIS data from the database and proceeds with the simulation considering navigation transit time, locks transit and lockage times.
Shaping Collaborative Work with Proto-patterns
Authors: Till Schümmer, Jörg M. Haake
Venue: Proceedings of the 2nd International Symposium on End-User Development (2009)

A shared set of processes and norms as well as a shared understanding of the collaboration infrastructure is a vital aspect for collaboration. This paper investigates how practitioners of virtual organizations can be supported in creating, sharing, and applying best practices that form the basis for a shared understanding of collaboration processes. Extending the interpretation of end-user development to a the development of processes and technology, best practice descriptions document proven social processes as well as guidelines for end-user appropriation and utilization of groupware tools. We propose a practice creation process, show how proto-patterns can be used for documenting best practice, and explain how they help to gain a socio-technical perspective on the shared practices. The approach has been used to create a best practice collection for efficient meetings.

Venue: Proceedings of the 8th IEEE/ACM International Conference on Grid Computing (2007)

Today’s large-scale scientific research often relies on the collaborative use of a Grid or e-Science infrastructure (e.g. DEISA, EGEE, TeraGrid, OSG) with computational, storage, or other types of physical resources. One of the goals of these emerging infrastructures is to support the work of scientists with advanced problem-solving tools. Many e-Science applications within these infrastructures aim at simulations of a scientific problem on powerful parallel computing resources. Typically, a researcher first performs a simulation for some fixed amount of time and then analyses results in a separate post-processing step, for instance, by viewing results in visualizations. In earlier work we have described early prototypes of a Collaborative Online Visualization and Steering (COVS) Framework in Grids that performs both - simulation and visualization - at the same time (online) to increase the efficiency of e-Scientists. This paper evaluates the evolved mature reference implementation of the COVS framework design that is ready for production usage within Web service-based Grid and e-Science infrastructures.

Venue: Proceedings of the IEEE International Conference on Multimedia Computing and Systems - Volume 2 (1999)

New multimedia smart phones that provide wireless voice and data communications services are becoming available. In this paper, a new user interface for a Personal Communications Services (PCS) smart phone is described. The user interface is designed around the unique characteristics of portable wireless applications. Both the physical characteristics of the phone and the way users interact with applications are unique. The phone has two LCD touch screens in a clamshell casing. It features pen input, handwriting recognition, and a graphical user interface supported by the Inferno operating system. A dedicated writing area and automatic text focus flow make form-based applications particularly easy. The smart phone also incorporates signature verification as a form of biometric authentication. The device apart from being a full-featured cellular voice phone also supports number of applications including web browsing, electronic mail, fax communications and directory application which allows users to retrieve contact information.

Collaborating centers in time zones six to eight hours apart can transfer work so that every center is working during the daytime. Although this concept avoids the hazards of night work, it requires careful planning and a way to automatically capture evolving knowledge.
Hybrid Super/Subthreshold Design of a Low Power Scalable-Throughput FFT Architecture
Authors: Michael B. Henry, Leyla Nazhandali
Venue: Proceedings of the 4th International Conference on High Performance Embedded Architectures and Compilers (2008)

In this paper, we present a parallel implementation of a 1024 point Fast Fourier Transform (FFT) operating at subthreshold voltage, which is below the voltage that turns the transistors on and off. Even though the transistors are not actually switching as usual in this region, they are able to complete the computation by modulating the leakage current that passes through them, resulting in a 20-100x decrease in power consumption. Our hybrid FFT design partitions a sequential butterfly FFT architecture into two regions, namely memory banks and processing elements, such that the former runs at superthreshold and the latter in the subthreshold voltage region. For a given throughput, the number of parallel processing units and their supply voltage is determined such that the overall power consumption of the design is minimized. For a 1024 point FFT operation, our parallel design is able to deliver the same throughput as a serial design, while consuming 65% less power. We study the effectiveness of this method for a variable throughput application such as a sensor node switching between a low throughput and high throughput mode, e.g. when sensing an interesting event. We compare our method with other methods used for throughput scaling such as voltage scaling and clock scaling and find that our scaling method will last up to three times longer on battery power.

Venue: New Frontiers in Applied Data Mining: PAKDD 2008 International Workshops, Osaka, Japan, May 20-23, 2008. Revised Selected Papers (2009)

In this paper, we study the problem of sorting a large collection of strings in external memory. Based on adaptive construction of a summary data structure, called adaptive synopsis trie, we present a practical string sorting algorithm DistStrSort, which is suitable for sorting string collections of large size in external memory, and also suitable for more complex string processing problems in text and semi-structured databases such as counting, aggregation, and statistics. Case analyses of the algorithm and experiments on real datasets show the efficiency of our algorithm in realistic setting.
Design guidelines for simulation building blocks
Authors: Alexander Verbraeck, Edwin C. Valentin
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Component based or building block based simulation model development is regularly mentioned as an interesting new development and a potential field of research. Most of the commercial simulation environments offer the users of their software functions to group model constructs and upgrade these to advanced model constructs that the users can use in future simulation studies. Unfortunately, the created model constructs are rarely reused and often stop being used after the first simulation study. In this paper we describe a list of guidelines to consider in the design of building blocks to enhance the reusability and the flexibility of the simulation building block to be used in multiple simulation studies, also by model developers who have not been involved in the design of the building blocks.
Representation of interrelationships among binary variables under dempster&ndash;shafer theory of belief functions
Authors: Rajendra P. Srivastava, Lei Gao, Peter R. Gillett
Venue: International Journal of Intelligent Systems (2009)

This paper presents an algorithm for developing models under Dempster&ndash;Shafer theory of belief functions for categorical and &ldquo;uncertain&rdquo; logical relationships among binary variables. We illustrate the use of the algorithm by developing belief-function representations of the following categorical relationships: &ldquo;AND,&rdquo; &ldquo;OR,&rdquo; &ldquo;exclusive OR (EOR)&rdquo; and &ldquo;not exclusive OR (NEOR),&rdquo; and &ldquo;AND-NEOR&rdquo; and of the following uncertain relationships: &ldquo;discounted AND,&rdquo; &ldquo;conditional OR,&rdquo; and &ldquo;weighted average.&rdquo; Such representations are needed to fully model and analyze a problem with a network of interrelated variables under Dempster&ndash;Shafer theory of belief functions. In addition, we compare our belief-function representation of the &ldquo;weighted average&rdquo; relationship with the &ldquo;weighted average&rdquo; representation developed and used by Shenoy and Shenoy (in Belief Functions in Business Decisions, edited by R. P. Srivastava and T. Mock; Heidelberg, Germany: Physica-Verlag; 2002; pp 316&ndash;332). We find that Shenoy and Shenoy representation of the weighted average relationship is an approximation and yields significantly different values under certain conditions. &copy; 2009 Wiley Periodicals, Inc.
Generating All Triangulations of Plane Graphs (Extended Abstract)
Authors: Mohammad Tanvir Parvez, Md. Saidur Rahman, Shin-Ichi Nakano
Venue: Proceedings of the 3rd International Workshop on Algorithms and Computation (2009)

In this paper, we deal with the problem of generating all triangulations of plane graphs. We give an algorithm for generating all triangulations of a triconnected plane graph G of n vertices. Our algorithm establishes a tree structure among the triangulations of G, called the "tree of triangulations," and generates each triangulation of G in O(1) time. The algorithm uses O(n) space and generates all triangulations of G without duplications. To the best of our knowledge, our algorithm is the first algorithm for generating all triangulations of a triconnected plane graph; although there exist algorithms for generating triangulated graphs with certain properties. Our algorithm for generating all triangulations of a triconnected plane graph needs to find all triangulations of a convex polygon. We give an algorithm to generate all triangulations of a convex polygon P of n vertices in time O(1) per triangulation, where the vertices of P are numbered. Our algorithm for generating all triangulations of a convex polygon also improves previous results; existing algorithms need to generate all triangulations of convex polygons of less than n vertices before generating the triangulations of a convex polygon of n vertices. Finally, we give an algorithm for generating all triangulations of a convex polygon P of n vertices in time O(n 2) per triangulation, where vertices of P are not numbered.

Authors: Fariza Hanum Nasaruddin, Maryam Zakeryfar, Rodina Ahmad
Venue: WSEAS Transactions on Information Science and Applications (2009)

The development of digital cardiac models has become an area of research all on its own. These researches intend to assist in the understanding of the heart. The data needed to build a digital cardiac model may come in various formats, including medical image data, such as MRI, CT scans, and other scans such as PET and SPECT. The availability of cardiac images is very important in cardiac modeling research. These images are difficult to come by for researchers who are not in the medical field. Thus, any of such available data stored in an on-line system can be made available to other researchers. This paper discusses and elaborates on the design and the development of this on-line cardiac image repository system. The requirement of the system was acquired using the Attribute Driven Design (ADD) method, which is a method for designing software architecture to satisfy both quality requirements and functional requirements. The online system which was developed has only taken into consideration image data, and not others formats of cardiac data such as ASCII flat files, and video files. The online system allows for downloading and uploading of data. With the availability of the data, researchers can spend more time focusing on the modeling processes rather than on the preprocessing and searching for data.

On partial detectability of the nonlinear dynamic systems
Authors: V. I. Vorotnikov, Yu. G. Martyshenko
Venue: Automation and Remote Control (2009)

Conditions were obtained under which the uniform stability (uniform asymptotic stability) in one part of the variables of the zero equilibrium position of the nonlinear nonstationary system of ordinary differential equations implies the uniform stability (uniform asymptotic stability) of this equilibrium position relative to another, larger part of variables. Conditions were also obtained under which the uniform stability (uniform asymptotic stability) in one part of variables of the "partial" (zero) equilibrium position of the nonlinear nonstationary system of ordinary differential equations implies the uniform stability (uniform asymptotic stability) of this equilibrium position. These conditions complement a number of the well-known results of the theory of partial stability and partial detectability of the nonlinear dynamic systems. Application of the results obtained to the problems of partial stabilization of the nonlinear control systems was considered.
Data integration flows for business intelligence

Venue: Proceedings of the 12th International Conference on Extending Database Technology: Advances in Database Technology (2009)

Business Intelligence (BI) refers to technologies, tools, and practices for collecting, integrating, analyzing, and presenting large volumes of information to enable better decision making. Today's BI architecture typically consists of a data warehouse (or one or more data marts), which consolidates data from several operational databases, and serves a variety of front-end querying, reporting, and analytic tools. The back-end of the architecture is a data integration pipeline for populating the data warehouse by extracting data from distributed and usually heterogeneous operational sources; cleansing, integrating and transforming the data; and loading it into the data warehouse. Since BI systems have been used primarily for off-line, strategic decision making, the traditional data integration pipeline is a oneway, batch process, usually implemented by extract-transform-load (ETL) tools. The design and implementation of the ETL pipeline is largely a labor-intensive activity, and typically consumes a large fraction of the effort in data warehousing projects. Increasingly, as enterprises become more automated, data-driven, and real-time, the BI architecture is evolving to support operational decision making. This imposes additional requirements and tradeoffs, resulting in even more complexity in the design of data integration flows. These include reducing the latency so that near real-time data can be delivered to the data warehouse, extracting information from a wider variety of data sources, extending the rigidly serial ETL pipeline to more general data flows, and considering alternative physical implementations. We describe the requirements for data integration flows in this next generation of operational BI system, the limitations of current technologies, the research challenges in meeting these requirements, and a framework for addressing these challenges. The goal is to facilitate the design and implementation of optimal flows to meet business requirements.

Venue: Proceedings of the May 6-10, 1974, national computer conference and exposition (1974)

The worldwide trend in computers in the 1970's has been the movement from off-line to on-line systems and the growing integration of computing and communications. It is expected that 70 percent of all computers will be connected to terminals via communication facilities by 1980. This trend has stimulated new applications for integrated systems, generically termed data or computer communications systems, and has broadened the current user base for existing applications.
