Abstract Web-based distributed volunteer computing enables scientists to constitute platforms that can be used for computational tasks by using potentially millions of computers connected to the internet. It is a widely used approach for many scientific projects, including the analysis of radio signals for signs of extraterrestrial intelligence and determining the mechanisms of protein folding. User adoption and clients' dependence on the desktop software present challenges in volunteer computing projects. This study presents a web-based volunteer computing framework for hydrological applications that requires only a web browser to participate in distributed computing projects. The framework provides distribution and scaling capabilities for projects with user bases of thousands of volunteers. As a case study, we tested and evaluated the proposed framework with a large-scale hydrological flood forecasting model.

AbstractFollowing the Great East Japan Earthquake on March 11, 2011, the Japan Medical Association deployed medical disaster teams to Shinchi-town (population: approximately 8,000), which is located 50 km north of the Fukushima Daiichi nuclear power plant. The mission of the medical disaster teams sent from Fukuoka, 1,400 km south of Fukushima, was to provide medical services and staff a temporary clinic for six weeks. Fear of radiation exposure restricted the use of large medical teams and local infrastructure. Therefore, small volunteer groups and a cloud-hosted, web-based electronic health record were implemented. The mission was successfully completed by the end of May 2011. Cloud-based electronic health records deployed using a “software as a service” model worked well during the response to the large-scale disaster.NagataT, HalamkaJ, KennochiH, HimenoS, HimenoA, HashizumeM.

The development of networks and web based environments combined with modern learning theories compose the new area of Learning Spaces aiming at enhancing interactive processes between educators, the Net generation's learners and the educational content. Collaboration at a distance (e-collaboration) supported by advanced learning technologies is today feasible and effective at a large scale opening up new perspectives in higher education. The paper presents a case study at the Hellenic Open University regarding the development of a learning sequence aimed at achieving high degrees of interactions among students, students and educators, and also at guiding them between face-to-face meetings when they prepare an essay. The Learning Space of the case study is realized by authoring sequences of learning activities using an LMS LAMS. Extending the case study, a methodology is illustrated to author collaborative sequences using LMS addressing to Open Universities in particular and also to conventional Universities in general.

PT INTI engaged in telecommunication, has long become a supplier of network construction with a large scale that is national. Therefore, PT INTI has a lot of material and spread all over the city in Indonesia. Previously, PT Inti still uses semi-manual way to do their material recording. The material recording is done by using Microsoft Excel which will be sent by electronic mail (email) if needed. But it is vulnerable to errors because the data contained in is not integrated. To overcome this, PT INTI wants to have a web based application called INTI Maintenance to manage financial materials such as material input, material search, material removal, material search, material data printing, to finance such as request addition, change of request status, delivery, and residual balances of each city. INTI Maintenance web-based information system financial module is built with open source software that uses PHP as the programming language, MySQL as the database, and Windows as server computer. The final results achieved in the material management information system in this module have advantages in assisting PT INTI employees in managing financial data and validation for material delivery using receipt of delivery material.   Keywords—information system, management, material, finance.

In biology, we are often confronted with information-rich, large-scale trajectory data, but exploring and communicating patterns in such data is often a cumbersome task. Ideally, the data should be wrapped with an interactive visualisation in one concise package that makes it straightforward to create and test hypotheses collaboratively. To address these challenges, we have developed a tool, linus, which makes the process of exploring and sharing 3D trajectories as easy as browsing a website. We provide a python script that reads trajectory data and enriches them with additional features, such as edge bundling or custom axes and generates an interactive web-based visualisation that can be shared offline and online. The goal of linus is to facilitate the collaborative discovery of patterns in complex trajectory data.

Grid Resource Broker

Portals to computational/data grids provide the scientific community with a friendly environment in order to solve large-scale computational problems. The Grid Resource Broker (GRB) is a grid portal that allows trusted users to create and handle computational/data grids on the fly exploiting a simple and friendly web-based GUI. GRB provides location-transparent secure access to Globus services, automatic discovery of resources matching the user's criteria, selection and scheduling on behalf of the user. Moreover, users are not required to learn Globus and they do not need to write specialized code or to rewrite their existing legacy codes. We describe GRB architecture, its components and current GRB features addressing the main differences between our approach and related work in the area.

Connected Government suggests provisioning of a government's services to its citizens using the Web and communications technologies employing the latest software development paradigms and related methodologies. This also requires appropriate integration of, and interaction between, software applications and e-services developed by various government departments as well as the other influencing sectors of the society such as commerce. This is especially so as the connected government (c-government) applications require open, flexible, interoperable, collaborative, and integrated architecture to provide services for the emerging technologies such as mobile, cloud, and big data. This, in turn, suggests a robust and standard mechanism to develop such applications and services. In this context, Service-Oriented Architecture (SOA) is an attractive approach to adopt. SOA has already been proven successful in providing such a framework for delivering software applications as services with flexibility and multi-platform and multi-channel integration that are necessarily required for c-government application offerings. This chapter provides a discussion of the SOA paradigm and the associated citizen and administrative requirements. The chapter also presents a service-oriented architectural framework based on a set of evaluated application characteristics that support newer technologies. A number of service-component models have also been proposed that provide required customisation, reuse, flexibility, and extensibility. In the context of the proposed overall service-oriented architecture, a large-scale sub-system that the authors term “e-Taxservice” has been used as a case study. The study has a service design that has been validated against a set of key service quality attributes.

Abstract The advent of high throughput next-generation sequencing technologies and improved assembly algorithms have resulted in the accumulation of voluminous genomic data in public domains. These technologies have opened up entries for large scale comparative genome studies, especially the identification of conserved syntenic blocks among species, facilitating studies of the evolutionary importance of the conservation and variation in genomic organization. Synteny construction and visualization require computational and bioinformatics skills to prepare input files for the synteny analysis pipeline. The syntenic information for fishes is still in a juvenile stage and is scattered among different research domains. Here, we present a web-based tool “Evol2Circos” to provide a user-friendly graphical user interface (GUI) to analyze user-specific data for synteny construction and visualization, and to facilitate the browsing of syntenic information of different fishes using the Circos, bar, dual, and dot plots. The information generated from the tool can also be used for further downstream analyses. Evol2Circos software tool is tested under Ubuntu Linux. The web-browser, source code, documentation, user manual, example dataset and scripts are available online at 203.190.147.148/evole2circos/
