Web Browser as an Application Platform

There are two essential ingredients for collecting information from the Internet: 1) a World Wide Web (Web) browser, and 2) an Internet search engine. The two most widely used Web browsers are Microsoft's Internet Explorer and Netscape Communications Corporation's Navigator. There are, however, more than 120 browser software possibilities available. These browsers have been cataloged by Adrian Roselli and may be found at Evolt, a site that supports the exchange of Web design information. Web browsers are like brands of shoes; some fit better than others. By visiting Evolt, whose uniform resource locator (URL) is listed below, one might find a browser that works better. For example, some Internet users prefer Firefox (Figure 1) and Safari, because Web browsers have different efficiencies in displaying Internet information on different computer platforms.

Evolt http://browsers.evolt.org/ As is the case with Web browsers, there are a number of Internet search engines. Each search engine has a variety of features that address different objectives for finding information from the Internet. The State University of New York at Albany has organized an excellent list of Internet search engines.

This paper presents a talking word processor and a talking web browser aimed at cognitively impaired individuals. Both the word processor and the web browser can display information and text and/or symbols. EdWord provides the user with a simple word-processor in which all objects, including menu items and tool tips are spoken. Microsoft Active Accessibility (MSAA) is used to implement this level of speech access; a feature which is unusual in simple word-processors. EdWeb uses a web browser component that linearises a web page into a single linear document. This style of interface has proved successful with a range of novice web users. Both EdWord and EdWeb are freely available.

We propose and study an evolving network model for instant messaging system (IMS) with local-world preferential connections and acquaintance introduction mechanisms, which exist in many physical complex networks especially in IMS evolving network. We put forward the algorithms to generate IMS evolving network model and through simulation results we talk about the topological properties of the IMS evolving network. First of all, degree distribution, clustering coefficient along with average path length are simulated and then the community structure of the model is analyzed. We can draw the conclusion that the degree distribution of IMS evolving network doesnpsilat obey power-law distribution, and this network has a short average path length and a high clustering coefficient. In a word, the simulation result shows that the IMS evolving network is a complex network possessing properties of small-world and clear community structure, but doesnpsilat have scale-free property.

The World Wide Web can be used a powerful and convenient means of disseminating computer aided education because most students already have access to the Web and the necessary Web browsers such as Netscape. There are many benefits in this approach because students already tend to do significant amounts of Internet surfing and are familiar with the usage of Web sites and browsers. Therefore online instruction for their coursework using this all pervasive computer network which may be accessed from almost anywhere is a powerful and beneficial low cost alternative to other forms of computer aided learning. The key aims of this package development are to provide a compact and self contained package of instruction in the features and facilities provided by the C programming language together with an introduction to the Unix programming environment with its vast range of utilities and command interpreter shells. Part of this introduction to Unix is provided in the Bourne Shell as a programming language instruction module.

The scope of the present work is to organize into a digital form and evaluate the excellent record of reported damages, connected to the occurrence of the 1978 Thessaloniki earthquake (M 6.5). For this purpose an advanced Information System with open architecture is under development. The system will include:• A properly designed database.• A Geographic Information System containing all the above data (after digitization and corrections) enriched with more recent data, as well as topographic, geological and geophysical data of the region (metropolitan area of Thessalonica).• A model system of accessing the above via web and mobile devices.The information system is designed with an open architecture so it can be easily adapted for use with similar data from other regions, and/or with other geographically distributed information with commercial importance. The data to be collected, stored and used will be described using XML language to facilitate communication among different applications and for flexible expansion to incorporate any new data types that have to be described and stored in the database. The use of XML is considered ideal both for back-end application logic, and as a platform for application and platforms integration. More specifically regarding the latter, methodologies will be developed for application integration based on XML-RPC and SOAP, which will enable flexible exchange of data with external systems and applications. The application will be available through the Internet so the interface of the application will be depicted through a Web Browser, using a desktop PC, a laptop, or - with some restrictions - a PDA.

We demonstrate proactive information retrieval via screen surveillance. A user's digital activities are continuously monitored by capturing all content on a user's screen using optical character recognition. This includes all applications and services being exploited and relies on each individual user's computer usage, such as their Web browsing, emails, instant messaging, and word processing. Topic modeling is then applied to detect the user's topical activity context to retrieve information. We demonstrate a system that proactively retrieves information from a user's activity history being observed on the screen when the user is performing unseen activities on a personal computer. We report an evaluation with ten participants that shows high user satisfaction and retrieval effectiveness. Our demonstration and experimental results show that surveillance of a user's screen can be used to build an extremely rich model of a user's digital activities across application boundaries and enable effective proactive information retrieval.

Everyday digital tasks can highly benefit from systems that recommend the right information to use at the right time. However, existing solutions typically support only specific applications and tasks. In this demo, we showcase EntityBot, a system that captures context across application boundaries and recommends information entities related to the current task. The user’s digital activity is continuously monitored by capturing all content on the computer screen using optical character recognition. This includes all applications and services being used and specific to individuals’ computer usages such as instant messaging, emailing, web browsing, and word processing. A linear model is then applied to detect the user’s task context to retrieve entities such as applications, documents, contact information, and several keywords determining the task. The system has been evaluated with real-world tasks, demonstrating that the recommendation had an impact on the tasks and led to high user satisfaction.

E-commerce, e-mail, e-greeting, e-this, and e-that everywhere you turn there is a new "e" word for an internet or Web application. We, at the Cleveland Clinic Foundation, have been "e-nlightened" and will discuss in this report the implementation of a web-based radiology information system (RIS) in our radiology division or "e-radiology" division. The application, IDXRad Version 10.0 from IDX Corp, Burlington, VT, is in use at the Cleveland Clinic Foundation and has both intranet (for use in Radiology) and internet (referring physician viewing) modules. We will concentrate on the features of using a web browser for the application's front-end, including easy prototyping for screen review, easier mock-ups of demonstrations by vendors and developers, and easier training as more people become web-addicted. Project communication can be facilitated with an internal project web page, and use of the web browser can accommodate quicker turnaround of software upgrades as the software code is centrally located. Compared with other technologies, including client/server, there is a smaller roll out cost when using a standard web browser. However, the new technology requires a change and changes are never implemented without challenges. A seasoned technologist using a legacy system can enter data quicker using function keys than using a graphical user interface and pointing and clicking through a series of pop-up windows. Also, effective use of a web browser depends on intuitive design for it to be easily implemented and accepted by the user. Some software packages will not work on both of the popular web browsers and then are tailored to specific release levels. As computer-based patient records become a standard, patient confidentiality must be enforced. The technical design and application security features that support the web-based software package will be discussed. Also web technologies have their own implementation issues.

Instant message system (IMS) is becoming increasingly an important means of communication except for traditional mass media. Based on the discussions about the characteristics of IMS message transfer, this paper firstly analyzed the specific characteristics different from traditional tools of communication and puts forward the principles of IMS message transfer. We also analyzed the characters of users in IMS virtual communities, and pointed out how these characters influencing the message transfer and how to control the message transfer correspondingly. We set up a Tobit model of IMS message transfer which includes five factors that may influence the transfer process. Through analyzing the sensitive factors of IMS message transfer, we demonstrate that there are two typical factors influencing IMS message transfer, which are whether a user is "active type" and the relationship types of IMS users. Finally, we proposed some necessary guidelines for enhancing the security of the IMS message transfer.

This paper aims at researching the message system in the instant messaging system based on the multi-language e-commerce platform in order to design the instant messaging system in multi-language environment and exhibit the national characteristics based information as well as applying national languages to e-commerce. In order to develop beautiful and friendly system interface for the front end of the message system and reduce the development cost, the mature jQuery framework is adopted in this paper. The high-performance server Tomcat is adopted at the back end to process user requests, and MySQL database is adopted for data storage to persistently store user data, and meanwhile Oracle database is adopted as the message buffer for system optimization. Moreover, AJAX technology is adopted for the client to actively pull the newest data from the server at the specified time. In practical application, the system has strong reliability, good expansibility, short response time, high system throughput capacity and high user concurrency.

In their everyday work people are confronted with ever growing amounts of information and thus often feel overloaded with data. Trails, built from information about the users' browsing paths and activities, are an established approach to assist users in navigating vast information spaces and finding appropriate information. While existing systems focus on web browsers only, we argue that trails can be generated by any application. We describe TrailTRECer, a framework which supports trail-based information access, and which is open to any application. The usability of the framework and the concept of user trails were tested by building a trail-enabled browser client and a print manager client. Initial user evaluations indicate the usefulness of this approach.

Smart TV terminals have become an emerging platform for both personal and business application. Security for applications running on smart TV terminals is important .In this paper we present TVOS, a new OS for enabling high assurance applications to run on smart TV terminal securely. Our main contributions are a new OS architecture and our use of formal methods for proving key security invariants about our implementation. As an operating system, TVOS is still relatively young. To analyze its security and tested its performance. Our evaluation shows that the performance of TVOS is comparable to an Android-based system. In one test, we ran the same web browser on TVOS and on an Android-based system and found that TVOS adds overhead on average to the page load latency time for nine popular web sites.

The goal of this project was to compare the functionality of the most widely used gaming platforms in terms of their applicability for telemedicine applications and to demonstrate the possibility of implementing a comprehensive telemedicine system using these platforms. We implemented a Home Automated Telemanagement (HAT) system for patients with chronic diseases to provide support in following their individualized treatment plans as well as to monitor symptoms, medication use, and quality of life, while educating the patient on their disease. The system was developed for use on the Nintendo Wii, the Microsoft Xbox 360, and the Sony Playstation 3. All three current generation videogame consoles allow for development of internet-based applications designed to be delivered via the console's web browsers. The HAT system was implemented to be placed in the patient's home and to communicate all patient data to a central server implementing real-time clinical decision support. The system questions patients daily on their condition, monitors their vital signs, and provides the patient with instant feedback on their condition. Cognitive walkthrough was used to see what challenges were posed by each platform and interface. We demonstrated that using any of the three gaming platforms it is possible to build a comprehensive telemedicine system that may be usable by patients with no prior computer or videogame experience.

We have invented a high-performance GPU based volume rendering algorithm on the ubiquitous WebGL platform. As WebGL is emerging as a standard platform for web applications on mobile devices, a remarkable advantage of our approach is that the advanced volume rendering algorithms can run directly on mobile devices such as smart phones and tablets in which GPU is embedded, anywhere and anytime. Technically, we deployed a novel single-pass rendering pipeline, in contrast to the other WebGL volume rendering systems using the multi-pass approach. We extended the pseudo-color shading and ray function blending by using a custom transfer function widget in the web browser, which enables interactive feature enhancement in rendering. And lastly, to get rid of the limitation in the loop iteration for dynamic loops on the current mobile platforms, we devised a WebGL compliant 3D texture slicer as an alternative solution to rendering of large datasets. Extensive experimental results and performance assessments are reported in the paper.
