A tool to estimate usability of Web 2.0 applications
2009
Nowadays, companies and home users use websites offering services ranging from web sites up to complex web applications. The ergonomics of these applications often remain unconsidered and the applications turn out to be hard to use. In this paper, a tool is presented to facilitate the examination of usability. Web 2.0 applications in particular are supported, because they are more flexible and require other techniques than traditional web applications. The paper explains how to collect, analyze, process and visualize usability data for Web 2.0 applications.
Semantic Web Services for Smart Devices in a “Global Understanding Environment”
2003
Various Web resources and services are usually assumed to be used and accessed by human users (current Web) or by software agents on behalf of human users (emerging Semantic Web). However industry emerges also a new group of “users”, which are smart industrial devices, robots or any other objects, which can be adapted to the (Semantic) Web environment. They would need special services for e.g. online condition monitoring, information provisioning, remote diagnostics, maintenance support, etc. The goal of this paper is to specify main requirements to Web services that automatically follow up and predict the performance and maintenance needs of field devices. Semantic Web enabled services for…
Emergent Web Intelligence: Advanced Semantic Technologies
2010
The future of the World Wide Web depended on its ability to understand and automatically process content to enable computers and people to work in cooperation. New advanced techniques and intelligent approaches are required more than ever to transform the Web into a universal reasoning and semantic-driven computing machine. The Web intelligence discipline attempts to deal with this challenge by exploits information technologies and artificial intelligence approaches to design next generation of web-empowered systems and services. The Emergent Web Intelligence: Advanced Semantic Technologies" book provides valuable references and cuttingedge technologies for: undergraduate and postgraduate s…
Web 2.0 patterns: A model-driven engineering approach
2012
Web Engineering methods, specifically Model-driven Engineering (MDE) ones, are not yet ready to cope with user involvement features that Web 2.0 is demanding. In this work, Web 2.0 patterns are introduced using conceptual models that represent both interaction and functionality, since in Web 2.0 applications both features are intertwined to support the user involvement concern. This work also drafts how Web 2.0 patterns can be integrated into models of a model-driven Web Engineering method.
Applying the ReMiP to Web Site Migration
2007
Web sites serve to publish information, both locally in intranets as well as on a global scale. Like all software systems, they have to cope with changing requirements and evolving technologies. The reference process model for software migration, ReMiP, provides a generic process model for software migration in general. The paper introduces ReMiP and summarises the application of a tailored ReMiP towards migrating a static HTML-based Web site to a content management system.
Ontosmartresource: an industrial resource generation in semantic web
2005
Semantic Web is a logical evolution of the existing Web. It was meant to serve for machines as today's Web does for humans. The term "machines" according to the existing semantic Web's vocabulary mostly means "computers". However industry needs such applications, which consider machines also as embedded computational entities within field devices, personal devices, microwave ovens, etc. In other words, now we should involve the real (industrial) world objects as resources into semantic Web. Still the main object of such a world will be a human, which becoming a resource (not just a user of resources) in the distributed environment. In this paper we introduce an extension of the semantic Web…
Proactively Composing Web Services as Tasks by Semantic Web Agents
2011
This chapter presents the framework for agent-enabled dynamic composition of Semantic Web services. The approach and the framework have been developed in several research and development projects by ISRG and IOG. The core of the methodology is the new understanding of a Semantic Web service as a capability of an intelligent software agent supplied with the proper ontological description. It is demonstrated how diverse Web services may be composed and mediated by dynamic coalitions of software agents collaboratively performing tasks for service requestors. Middle agent layer is introduced to conduct the transformation of a Web service request to the corresponding task, agent-enabled cooperat…
Orthonasal aroma characteristics of Spanish red wines from different price categories and their relationship to expert quality judgements
2012
Background and Aims: Research aimed to define the olfactory sensory spaces of Spanish red wines from different price segments and to determine relationships between sensory descriptors and quality as evaluated by experts. Methods and Results: A trained panel using a frequency of citation method assessed the orthonasal sensory characteristics of 96 Spanish wines belonging to three price segments (premium; high standard; low standard). Eleven robust sensory terms were built by combining similar terms using statistical criteria. A panel of experts consistently assessed quality. Negative aroma profiles, some of them very skewed, were identified in the different sets with 'animal', 'undergrowth'…
Modified Gaussian models applied to the description and deconvolution of peaks in chiral liquid chromatography.
2020
Abstract The description of the profiles of chromatographic peaks has been studied extensively, with a large number of proposed mathematical functions. Among them, the accuracy achieved with modified Gaussian models that describe the deviation of an ideal Gaussian peak as a change in the peak variance or standard deviation over time, has been highlighted. These models are, in fact, a family of functions of different complexity with great flexibility to adjust chromatographic peaks over a wide range of asymmetries and shapes. However, an uncontrolled behaviour of the signal may occur outside the region being fitted, forcing the use of different strategies to overcome this problem. In this wo…
Grand-canonical approach to density functional theory of electrocatalytic systems: Thermodynamics of solid-liquid interfaces at constant ion and elec…
2018
Properties of solid-liquid interfaces are of immense importance for electrocatalytic and electrochemical systems, but modeling such interfaces at the atomic level presents a serious challenge and approaches beyond standard methodologies are needed. An atomistic computational scheme needs to treat at least part of the system quantum mechanically to describe adsorption and reactions, while the entire system is in thermal equilibrium. The experimentally relevant macroscopic control variables are temperature, electrode potential, and the choice of the solvent and ions, and these need to be explicitly included in the computational model as well; this calls for a thermodynamic ensemble with fixed…
