With the ubiquitous availability of browsers and Internet access, the last few years have seen a tremendous growth in the number of applications being developed on the World Wide Web (WWW). Models for analyzing and designing these applications are only just beginning to emerge. In this work, we propose a three-dimensional classification space for WWW applications, consisting of a degree of structure of pages dimension, a degree of support for interrelated events dimension, and a location of processing dimension. Next, we propose usability design metrics for WWW applications along the structure of pages dimension. To measure these, we propose CMU-WEB–a conceptual model that can be used to design WWW applications, such that its schema provide values for the design metrics. This work represents the first effort, to the best of our knowledge, to provide a conceptual model that measures quantifiable metrics that can be used for the design of more usable Web applications, and that can also be used to compare the usability of existing Web applications, without empirical testing.

The increased dependency on the World Wide Web by both laboratories and their customers has led LIMS developers to take advantage of thin-client web applications that provide both remote data entry and manipulation, along with remote reporting functionality. Use of an LIMS through a web browser allows a person to interact with a distant application, providing both remote administration and real-time analytical result delivery from virtually anywhere in the world. While there are many benefits of web-based LIMS applications, some concern must be given to these new methods of system architecture before justifying them as a suitable replacement for their traditional client-server systems. Developers and consumers alike must consider the security aspects of introducing a wide area network capable system into a production environment, as well as the concerns of data integrity and usability.

Accessing the Web from mobile devices is a popular practice. Trends show that the mobile space is becoming the method through which many consumers access content – both through native and web applications. These applications have expanded the browsing experience, but have also complicated the development process. A need exists for a simple, uniform solution which HTML5 is attempting to address. HTML is a mark-up language, now on its fifth edition, used for structuring and presenting content on the World Wide Web. Because of the large increase in users of mobile devices, internet access on these devices is widely used. The creation of web sites, web documents, and applications are done with HTML5, as it is compatible with both PC and mobile device browsers. However, with its lengthy development process, it is not yet apparent if HTML5 can incorporate the demands of developers in a changing environment. This paper provides an overview of the use of HTML5 in structuring and presenting content on the World Wide Web and compatibility issues on mobile browsers, key features, tool’s, and the advantages and disadvantages on the mobile web devices as well as the state of the mobile web.

That portion of the Internet known as the World Wide Web has been riding an exponential growth curve since 1994 (Network Wizards, 1999; Rutkowski, 1998), coinciding with the introduction of NCSA’s graphically based software interface Mosaic for “browsing” the World Wide Web (Hoffman, Novak, & Chatterjee 1995). Currently, over 43 million hosts are connected to the Internet worldwide (Network Wizards, 1999). In terms of individual users, somewhere between 40 to 80 million adults (eStats, 1999) in the United States alone have access to around 800 million unique pages of content (Lawrence & Giles, 1999), globally distributed on arguably one of the most important communication innovations in history. Yet even as the Internet races ambitiously toward critical mass, some social scientists have begun to examine carefully the policy implications of current demographic patterns of Internet access and usage (Hoffman & Novak, 1998; Hoffman, Kalsbeek, & Novak, 1996; Hoffman, Novak, & Venkatesh, 1997; Katz & Aspden, 1997; Wilhelm, 1998). Looming large is the concern that the Internet may not scale economically (Keller, 1996), leading to what Lloyd Morrisett, the former president of the Markle Foundation, has called a “digital divide” between the information “haves” and “have-nots.” For example, although almost 70% of the schools in this country have at least one computer connected to the Internet, less than 15% of classrooms have Internet access (Harmon, 1997). Not surprisingly, access is not distributed randomly, but correlated strongly with income and education (Coley, Cradler, & Engel 1997). A recent study of Internet use among college freshman (Sax, Astin, Korn, & Mahoney 1998) found that nearly 83% of all new college students report using the Internet for school work, and almost two-thirds use e-mail to communicate. Yet, closer examination suggests a disturbing disparity in access. While 90.2% of private college freshman use the Internet for research, only 77.6% of students entering public black colleges report doing so. Similarly, although 80.1% of private college freshman use e-mail regularly, only 41.4% of students attending black public colleges do. Further, although numerous studies (e.g., CyberAtlas, 1999; Maraganore & Morrisette, 1998) suggest that the gender gap in Internet use appears to be closing over time and that Internet users are increasingly coming from the ranks of those with lower education and income (Pew Research Center, 1998), the perception persists that the gap for race is not decreasing (Abrams, 1997). We now raise a series of points for further discussion. We believe these issues represent the most pressing unanswered questions concerning access and the impact of the digital divide on the emerging digital economy. This article is intended to stimulate discussion among scholars and policymakers interested in how differences in Internet access and use among different segments in our society affect their ability to participate and reap the rewards of that participation in the emerging digital economy. In summary, we have reviewed the most recent research investigating the relationship of race to Internet access and usage over time. Our objective is twofold: (1) to stimulate an informed discussion among scholars and policymakers interested in the issue of diversity on the Internet, and 2) to propose a research agenda that can address the many questions raised by this and related research.

The evolution of the World Wide Web from hypermedia information repositories to web applications such as social networking, wikis or blogs has introduced a new paradigm where users are no longer passive web consumers. Instead, users have become active con- tributors to web applications, so introducing a high level of dynamism in their behavior. Moreover, this trend is even expected to rise in the incoming Web. As a consequence, there is a need to develop new software tools that consider user dynamism in an appropiate and accurate way when generating dynamic workload for evaluating the performance of the current and incoming web. This paper presents a new testbed with the ability of defining and generating web dy- namic workload for e-commerce. For this purpose, we integrated a dynamic workload generator (GUERNICA) with a widely used benchmark for e-commerce (TPC-W).

The World Wide Web (WWW) has become the most widely used platform for application development and information delivery. Web applications have evolved from static, read-only Web sites to current, collaborative, mobile, and pervasive information systems. Most companies are automating their core work flows using Web technologies; new businesses supported by the provision of complex Web services appear every day.

This paper reports the availability of a database of protein structural domains (DDBASE), an alignment database of homologous proteins (HOMSTRAD) and a database of structurally aligned superfamilies (CAMPASS) on the World Wide Web (WWW). DDBASE contains information on the organization of structural domains and their boundaries; it includes only one representative domain from each of the homologous families. This database has been derived by identifying the presence of structural domains in proteins on the basis of inter-secondary structural distances using the programDIAL[Sowdhamini & Blundell (1995),Protein Sci.4, 506–520]. The alignment of proteins in superfamilies has been performed on the basis of the structural features and relationships of individual residues using the programCOMPARER[Sali & Blundell (1990),J. Mol. Biol.212, 403–428]. The alignment databases contain information on the conserved structural features in homologous proteins and those belonging to superfamilies. Available data include the sequence alignments in structure-annotated formats and the provision for viewing superposed structures of proteins using a graphical interface. Such information, which is freely accessible on the WWW, should be of value to crystallographers in the comparison of newly determined protein structures with previously identified protein domains or existing families.
