Since its inception of just over two decades ago, the World Wide Web has become a truly ubiquitous and transformative force in our life, with millions of Web applications serving billions of Web pages daily. Through a number of evolutions, Web applications have become interactive, dynamic and asynchronous. The Web׳s ubiquity and our reliance on it have made it imperative to ensure the quality, security and correctness of Web applications. Testing is a widely used technique for validating Web applications. It is also a long-standing, active and diverse research area. In this paper, we present a broad survey of recent Web testing advances and discuss their goals, targets, techniques employed, inputs/outputs and stopping criteria. 相似文献

Abstract The World Wide Web (WWW) has a decentralized information environment and a non-linear (hypertext) information structure. This non-linear structure allows users to retrieve information at many different levels but also increases the difficulty of information retrieval. Unlike a well-developed CD-ROM database, the WWW does not have a controlled searching environment and information can be indexed in many different ways. It takes a well planned search strategy to perform an effective search in the labyrinth of the WWW. The SIRO (Systematic Information Retrieval/Organization) model offers a research planning process designed specifically for information seekers in the agricultural disciplines. The intention is to enhance search results and organize retrieved information. This process starts with the identification of the information structure on the WWW, then proceeds by organizing and analyzing information in a visual diagram or a “thinking map.” This process leads searchers to logical sources on the WWW and a systematic analysis of the result. 相似文献

Letters, notes, and above all an original notebook by Luigi Sacco dated 1916 have shed new light on the establishment and development of the “Ufficio (or Reparto) Crittografico” of the Italian Army Headquarters in World War I. Three decrypted messages, unpublished until now, are included with Sacco’s comments. 相似文献

This study contributes to international news flow literature methodologically, by significantly expanding its scope, and theoretically, by incorporating intermedia agenda-setting theory, through which we reveal how news media in different countries influence each other in covering international news. With a big data analysis of 4,708 online news sources from 67 countries in 2015, the study shows that wealthier countries not only continue to attract most of the world news attention, they are also more likely to decide how other countries perceive the world. However, international news flow is not as hierarchical and U.S.-centric as found earlier. Online-only, emerging media in core countries are not necessarily more impactful in setting the world news agenda than those in (semi)peripheral countries. 相似文献

In this paper, we propose a novel methodology to define and estimate a surrogate measure. By imposing a hypothetical disturbance to the leading vehicle, the following vehicle’s action is represented as a probabilistic causal model. After that, a tree is built to describe the eight possible conflict types under the model. The surrogate measure, named Aggregated Crash Index (ACI), is thus proposed to measure the crash risk. This index reflects the accommodability of freeway traffic state to a traffic disturbance. We further apply this measure to evaluate the crash risks in a freeway section of Pacific Motorway, Australia. The results show that the proposed indicator outperforms the three traditional crash surrogate measures (i.e., Time to Collision, Proportion of Stopping Distance, and Crash Potential Index) in representing rear-end crash risks. The applications of this measure are also discussed. 相似文献

Federica Goffi 《Architectural Design》2016,86(1):24-33
Differentiating between the static impulse to preserve and the more open-ended and imaginative process of conservation, Federica Goffi presents a building as ‘a fabric that, even when complete, is unfinished and open to change’. Associate Professor and Associate Director of Graduate Programs at the Azrieli School of Architecture and Urbanism at Carleton University in Ottawa, Goffi has written widely on the topic of time, particularly taking St Peter's in the Vatican by way of example. 相似文献

An awakening interest in public space in Brazilian cities is emphasising the value of existing civic areas. Guilherme Wisnik , a critic, curator and professor at the Faculty of Architecture and Urbanism of the University of São Paulo, looks at the history and potential future of Brazil's urban spaces. He highlights how despite the introduction of innovative Modernist design in the mid-20th century, which forged ‘a new relationship between architecture, urbanism and landscape design’, more recently the country's cities have been subject to the vicissitudes of market and political forces. 相似文献

Patents are the strongest form of intellectual property rights available internationally, so far unbeaten by open source as a body of innovation and know-how. Mark Garcia , senior lecturer in the Department of Architecture & Landscape at the University of Greenwich, London, here considers the pros and cons of the patent system for architects in the digital age: from issues over patent categorisation by type, to possibilities of micro-royalties through the capacity of design software to track every stage of input from multiple contributors. 相似文献

Film production requires world building: the power to visualise and bring to life narrative through a film's total environment. This is often entirely speculative, imagining alternative or future worlds. Here, Alex McDowell , acclaimed British production designer, producer and Professor at the University of Southern California (USC) describes his world-building, narrative approach to production design, which he consolidated in the Steven Spielberg film Minority Report (2002) that envisioned Washington DC in the year 2050. The possibilities of this storytelling technique are demonstrated by its transference into real-life projects, such as the immersive model that his production company, 5D GlobalStudio, developed for Al Baydha, a Bedouin village in Saudi Arabia. 相似文献
