A cloud-based multimodality case file for mobile devices.

Recent improvements in Web and mobile technology, along with the widespread use of handheld devices in radiology education, provide unique opportunities for creating scalable, universally accessible, portable image-rich radiology case files. A cloud database and a Web-based application for radiologic images were developed to create a mobile case file with reasonable usability, download performance, and image quality for teaching purposes. A total of 75 radiology cases related to breast, thoracic, gastrointestinal, musculoskeletal, and neuroimaging subspecialties were included in the database. Breast imaging cases are the focus of this article, as they best demonstrate handheld display capabilities across a wide variety of modalities. This case subset also illustrates methods for adapting radiologic content to cloud platforms and mobile devices. Readers will gain practical knowledge about storage and retrieval of cloud-based imaging data, an awareness of techniques used to adapt scrollable and high-resolution imaging content for the Web, and an appreciation for optimizing images for handheld devices. The evaluation of this software demonstrates the feasibility of adapting images from most imaging modalities to mobile devices, even in cases of full-field digital mammograms, where high resolution is required to represent subtle pathologic features. The cloud platform allows cases to be added and modified in real time by using only a standard Web browser with no application-specific software. Challenges remain in developing efficient ways to generate, modify, and upload radiologic and supplementary teaching content to this cloud-based platform. Online supplemental material is available for this article.

The Package Blueprint: Visually analyzing and quantifying packages dependencies

Large object-oriented applications are structured over many packages. Packages are important but complex structural entities that are difficult to understand since they act as containers of classes, which can have many dependencies with other classes spread over multiple packages. However to be able to take decisions (e.g. refactoring and/or assessment decisions), maintainers face the challenges of managing (sorting, grouping) the massive amount of dependencies between classes spread over multiple packages. To help maintainers, there is a need for at the same time understanding, and quantifying, dependencies between classes as well as understanding how packages as containers of such classes depend on each other.In this paper, we present a visualization, named Package Blueprint, that reveals in detail package internal structure, as well as the dependencies between an observed package and its neighbors, at both package and class levels. Package blueprint aims at assisting maintainers in understanding package structure and dependencies, in particular when they focus on few packages and want to take refactoring decisions and/or to assess the structure of those packages. A package blueprint is a space filling matrix-based visualization, using two placement strategies that are enclosure and adjacency. Package blueprint is structured around the notion of surfaces that group classes and their dependencies by their packages (i.e., enclosure placement); whilst surfaces are placed next to their parent node which is the package under-analysis (i.e., adjacency placement). We present two views: one stressing how an observed package depends upon the rest of the system and another stressing how the system depends upon that package.To evaluate the contribution of package blueprint for understanding packages we performed an exploratory user study comparing package blueprint with an advanced IDE. The results show that users of package blueprint are faster in analyzing and assessing package structure. The results are proved statically significant and they show that package blueprint considerably improves the experience of standard browser users.

Flood Finder: Mobile-based automated water level estimation and mapping during floods

Every year, Southeast Asia faces numerous flooding disasters, resulting in very high human and economic loss. Responding to a sudden flood is difficult due to the lack of accurate and up-to- date information about the incoming water status. We have developed a mobile application called Flood Finder to solve this problem. Flood Finder allows smartphone users to measure, share and search for water level information at specified locations. The application uses image processing to compute the water level from a photo taken by users. The photo must be of a known reference object with a standard size. These water levels are more reliable and consistent than human estimates since they are derived from an algorithmic measuring function. Flood Finder uploads water level readings to the server, where they can be searched and mapped by other users via the mobile phone app or standard browsers. Given the widespread availability of smartphones in Asia, Flood Finder can provide more accurate and up-to-date information for better preparation for a flood disaster as well as life safety and property protection.

Web-based spatiotemporal simulation modeling and visualization of tsunami inundation and potential human response

Modeling spatiotemporal phenomena can provide insight into potential behavior of simulated objects during hypothetical events. Simulation frameworks can be a useful method of modeling these scenarios, and become more flexible when developed in a fashion that facilitates automated generation of output based on variable input parameters. By connecting a simulation framework to a web-based system, a user can assign input parameters of their choosing, run a simulation, and explore the output data in a dynamic, animated, map-based context using a standard web browser. The framework described here utilizes tsunami simulation data and user input to generate a combined web-based visualization and simulation model of human response to tsunami inundation. Input parameters pertaining to human population and community of interest are provided by the user and guide automated development of a simulation model scenario of spatiotemporal human response to a hypothetical tsunami inundation event. Simulated human movement is calculated at each time step using casualty model algorithms informed by behavioral research and variables such as water depth and road networks, while a mix of server-side and client-side code renders the mapping interface and supports user interaction within the web browser. Interactive controls included in the web-based simulation viewer allow the user to manipulate the map display and query underlying data either manually by time step or interactively while animation is underway. Although modeling of human movement has inherent limitations, integration of a formal casualty model with the automated simulation framework represents a unique quantitative approach for casualty determination and simulation modeling.

Doubly Fed Induction Machine Drive Hardware Laboratory for Distance Learning Education

This paper presents the technology and user interface developed to create a doubly fed induction machine (DFIM) remotely controlled hardware laboratory for DL education. The new laboratory is designed to reinforce the theory learned in class and to verify that modeling and simulations of the laboratory machine are accurate. The power conversion system is controlled by two field-programmable gate array-based controllers which communicate with a web server PC through a USB interface so that the laboratory can be executed on campus as well as remotely. The remote students only need access to a PC with Internet connection and a standard browser, without the need to install any software or modify its security settings. The pedagogical value of this laboratory is reinforced by positive student's feedback.

Communication Platform for Image Analysis and Sharing in Biology

Image analysis is crucial to medical and biological applications. Recent advances in imaging technology have led to the demand for processing and visualizing a large amount of three-dimensional (3D) biomedical images. In addition, cloud computing has become popular for managing big data. Unfortunately, conventional image-processing systems either lack cloud computing services or advanced 3D processing abilities. In this paper, we present a novel cloud-based system for sharing, processing, and visualizing 3D biomedical images. Our system employs a standard web browser as a client interface that interactively communicates with high-performance servers. Thus, an inexpensive tablet PC without an advanced graphics processing unit (GPU) can be used for 3D image processing and visualization. Our system provides the sharing of limited software and hardware resources, and it allows for effective collaboration between researchers. We demonstrate the applicability and functionality of the system by examining typical case studies on biomed- ical images. We also examine the performance of our system numerically.Â

ProfileDB: A resource for proteomics and cross-omics biomarker discovery

The increasing size and complexity of high-throughput datasets pose a growing challenge for researchers. Often very different (cross-omics) techniques with individual data analysis pipelines are employed making a unified biomarker discovery strategy and a direct comparison of different experiments difficult and time consuming. Here we present the comprehensive web-based application ProfileDB. The application is designed to integrate data from different high-throughput ‘omics’ data types (Transcriptomics, Proteomics, Metabolomics) with clinical parameters and prior knowledge on pathways and ontologies. Beyond data storage, ProfileDB provides a set of dedicated tools for study inspection and data visualization. The user can gain insights into a complex experiment with just a few mouse clicks. We will demonstrate the application by presenting typical use cases for the identification of proteomics biomarkers. All presented analyses can be reproduced using the public ProfileDB web server. The ProfileDB application is available by standard browser (Firefox 18+, Internet Explorer Version 9+) technology via http://profileDB.-microdiscovery.de/ (login and pass−word: profileDB). The installation contains several public datasets including different cross-‘omics’ experiments. This article is part of a Special Issue entitled: Biomarkers: A Proteomic Challenge.

Nucleating the development of telemedicine to support healthcare workers in resource-limited settings: a new approach

Collegium Telemedicus (CT) offers a new approach to the problem of starting a store-and-forward telemedicine network for use in low resource settings. The CT organization provides a no-cost template to allow groups to start a network without delay, together with a peer-support environment for those operating the networks. A new group needs only to supply a Guarantor (who accepts responsibility for the work of the network) and a Coordinator (who operates the telemedicine network, allocating cases and ensuring that they are responded to). Communication takes place via secure messaging, which has several advantages over plain email, e.g. all the data are stored centrally, which means that they can be read from a hand-held device such as a smart phone, but do not need to be stored on that device. Users can access the system with a standard web browser. In the first three months, seven networks were established on the CT system by university groups in the US, the UK, Australia and New Zealand, and by a large, multinational humanitarian organisation. In the most active network, there were 86 telemedicine cases in the first three months, i.e. an average submission rate of 7 cases/week. The CT system appears to fulfil its aim of assisting doctors who wish to help colleagues in other countries by improving their access to specialist opinions, while allowing them to maintain control over the new network's use and development. The long term aim of the CT organization is to provide a means of improving the quality of health care at the point of delivery in low resource settings.

Personal Health Book: A Cloud-Based Tool for Patient Centered Healthcare

Patient centered healthcare is based on the assumption that physicians, patients and their families have the ability to obtain and understand health information and services, and make appropriate health decisions. This in turn presumes that patient’s personal health information is presented according to individuals understanding and abilities. Based on this argument our research has focused on analysing whether the existing PHRs (Personal Health Records) support patient centered healthcare in an appropriate way. The analysis of these questions led to the introduction of the Personal Health Book (PHB). It is an extension of PHR in that all healthcare providers augment the PHB by links to relevant information entities. We can exploit cloud computing in accessing the PHB as anyone with a suitable Internet connection and a standard browser can access an application in a cloud. In this paper we consider two approaches for maintaining PHBs: one extends XML based PHRs while the other exploits semantic web technologies in PHBs’ implementation. In particular, we present the advantages that can be achieved in using cloud computing and semantic web technologies such as RDF and OWL.

Recent innovations in Distributed Systems: Challenges and Benefits

The World Wide Web is used by millions of people everyday for various purposes including email, reading news, downloading music, online shopping or simply accessing information about anything. Using a standard web browser, the user can access information stored on Web servers situated anywhere on the globe. This gives the illusion that all this information is situated locally on the user’s computer. In reality, the Web represents a huge distributed system that appears as a single resource to the user available at the click of a button. This paper gives an overview of distributed systems in current IT sector. Distributed systems are everywhere. The internet enable users throughout the world to access its services wherever they may be located [1]. Each organization manages an intranet, which provides local services for local users and generally provides services to other users in the internet. Small distributed systems can be constructed from mobile computers and other small computational devices that are attached to a wireless network.

Web Service for extracting stream networks from DEM data

This paper describes the implementation of a morphology based algorithm for extracting stream networks from data as a Web Service within the framework of GeoBrain, an open, interoperable, distributed, standard-compliant, multi-tier web-based geospatial information services and knowledge building system. Unlike standard out-of-the-box GIS software, which uses the flow direction based algorithm and often produces streams that are spatially uniform, streams extracted with this Web Service correctly reflect spatial variability in dissection patterns. In addition, this Web Service is free and can be accessed from anywhere provided that there is an Internet connection and a standard Web browser.

Can Social Semantic Web Techniques Foster Collaborative Curriculum Mapping In Medicine?

BackgroundCurriculum mapping, which is aimed at the systematic realignment of the planned, taught, and learned curriculum, is considered a challenging and ongoing effort in medical education. Second-generation curriculum managing systems foster knowledge management processes including curriculum mapping in order to give comprehensive support to learners, teachers, and administrators. The large quantity of custom-built software in this field indicates a shortcoming of available IT tools and standards.ObjectiveThe project reported here aims at the systematic adoption of techniques and standards of the Social Semantic Web to implement collaborative curriculum mapping for a complete medical model curriculum.MethodsA semantic MediaWiki (SMW)-based Web application has been introduced as a platform for the elicitation and revision process of the Aachen Catalogue of Learning Objectives (ACLO). The semantic wiki uses a domain model of the curricular context and offers structured (form-based) data entry, multiple views, structured querying, semantic indexing, and commenting for learning objectives (“LOs”). Semantic indexing of learning objectives relies on both a controlled vocabulary of international medical classifications (ICD, MeSH) and a folksonomy maintained by the users. An additional module supporting the global checking of consistency complements the semantic wiki. Statements of the Object Constraint Language define the consistency criteria. We evaluated the application by a scenario-based formative usability study, where the participants solved tasks in the (fictional) context of 7 typical situations and answered a questionnaire containing Likert-scaled items and free-text questions.ResultsAt present, ACLO contains roughly 5350 operational (ie, specific and measurable) objectives acquired during the last 25 months. The wiki-based user interface uses 13 online forms for data entry and 4 online forms for flexible searches of LOs, and all the forms are accessible by standard Web browsers. The formative usability study yielded positive results (median rating of 2 (“good”) in all 7 general usability items) and produced valuable qualitative feedback, especially concerning navigation and comprehensibility. Although not asked to, the participants (n=5) detected critical aspects of the curriculum (similar learning objectives addressed repeatedly and missing objectives), thus proving the system’s ability to support curriculum revision.ConclusionsThe SMW-based approach enabled an agile implementation of computer-supported knowledge management. The approach, based on standard Social Semantic Web formats and technology, represents a feasible and effectively applicable compromise between answering to the individual requirements of curriculum management at a particular medical school and using proprietary systems.

The UCSC Interaction Browser: multidimensional data views in pathway context

High-throughput data sets such as genome-wide protein–protein interactions, protein–DNA interactions and gene expression data have been published for several model systems, especially for human cancer samples. The University of California, Santa Cruz (UCSC) Interaction Browser (http://sysbio.soe.ucsc.edu/nets) is an online tool for biologists to view high-throughput data sets simultaneously for the analysis of functional relationships between biological entities. Users can access several public interaction networks and functional genomics data sets through the portal as well as upload their own networks and data sets for analysis. Users can navigate through correlative relationships for focused sets of genes belonging to biological pathways using a standard web browser. Using a new visual modality called the CircleMap, multiple ‘omics’ data sets can be viewed simultaneously within the context of curated, predicted, directed and undirected regulatory interactions. The Interaction Browser provides an integrative viewing of biological networks based on the consensus of many observations about genes and their products, which may provide new insights about normal and disease processes not obvious from any isolated data set.

Three Digital Platforms: Hangzhou Public Library Widens Access to Resources

This article investigates the "three digital platforms" of Hangzhou Public Library 杭州图书馆 through a discussion of information inequality, the digital divide, and community informatics. After an introduction to the context of contemporary China, and in particular Hangzhou, the authors consider the resources themselves with special reference to their ability to reduce information inequality. These resources—the "Three Platforms" referenced in the title of this essay—are: the library's Website (which can be accessed through standard browser applications), a Wireless Application Protocol (WAP) service that is available to mobile users, and a unique digital television service (that is supplied in collaboration with a local cable television company). As part of this discussion, the authors provide data on the number of users and views each service has had in the time since their implementation; offer detailed information on the profile of Website use and the numbers of library patrons taking part in library activities; assess the impact of these services; and debate their implications for community informatics and digital inequality in Hangzhou. Finally, the authors discuss potential future developments.

The web portal is developed using open source software: PHP, JQuery, R and OpenBUGS. It supports any standard browsers with internet connection. The web portal can be accessed at: http://biostatistics.csmc.edu.

COPRED: prediction of fold, GO molecular function and functional residues at the domain level

Only recently the first resources devoted to the functional annotation of proteins at the domain level started to appear. The next step is to develop specific methodologies for predicting function at the domain level based on these resources, and to implement them in web servers to be used by the community. In this work, we present COPRED, a web server for the concomitant prediction of fold, molecular function and functional sites at the domain level, based on a methodology for domain molecular function prediction and a resource of domain functional annotations previously developed and benchmarked. COPRED can be freely accessed at http://csbg.cnb.csic.es/copred. The interface works in all standard web browsers. WebGL (natively supported by most browsers) is required for the in-line preview and manipulation of protein 3D structures. The website includes a detailed help section and usage examples. pazos@cnb.csic.es.

Dynamic Linking and Personalization on the Web using Linked Open Data

This paper presents a novel Semantic Web browser, called SemWeB. SemWeB supports Web browsing using Linked Open Data and personalization. This is the first time a Semantic Web browser combines the advances in Adaptive Hypermedia (i.e. personalization) and Linked Open Data. In particular, users are provided with a personalized and semantically rich Web browsing experience. For example, SemWeB supplies goal-based adaptive information retrieval from the LOD, adaptive link recommendation using a novel semantic relatedness measure and adaptive content creation. A user based study was used to assess the value of LOD-based hyperlinks and personally relevant content compared with a standard Web browser (Firefox). Results showed that users were able to browse and view more relevant information, as well as, value significance of LOD-based hyperlinks and personalized content in comparison to a standard Web browser.

Canadian Cardiovascular Society/Canadian Heart Rhythm Society Joint Position Statement on the Use of Remote Monitoring for Cardiovascular Implantable Electronic Device Follow-up

Remote monitoring (RM) is a form of telemedicine technology that permits implanted pacemakers and implantable cardioverter-defibrillators to transmit diagnostic information for review by health care professionals without patients needing to visit the device follow-up clinic. A bedside transmitter in the patient's home conveys the device data using standard telecommunication protocol to a protected internet-accessible RM data server, which authorized health care professionals can access at any time using standard web browser software. Evidence indicates it can accelerate identification of clinical events and potential device problems. RM raises important medicolegal issues concerning the protection of a patient's rights and the safeguarding of patient health information related to the collection, storage, and use of patient device information that must be addressed by follow-up centres. This position statement recommends that remote monitoring be available at all device follow-up clinics as an integral part of the standard of care of device patients and also provides helpful advice to centres for the proper design, implementation, and integration of a remote monitoring system into the clinic.
