  • Safety/Reliability engineering did not develop as a unified discipline, but grew out of the integration of a number of activities, previously the province of various branches of engineering. Since no human activity can enjoy zero risk, and no equipment has a zero rate of failure, there has emerged a safety technology for optimizing risk. This attempts to balance the risk of a given activity against its benefits and seeks to assess the need for further risk reduction depending upon the cost.

  • However, double mode will also cause a redundancy effect. Diao and Sweller (2007) conducted a study with university students which demonstrated that text-only presentation mode was better than synchronised sound and text presentation mode, for both performance and cognitive load. This result supported the proposition that the redundancy effect occurs when sound is presented simultaneously with text, which is not beneficial to learning. However, this study did not take learners’ prior knowledge into account. A Chinese learning study, with high school...

  • A case study is a way to test the applicability of a theory using real-world evidence. The intent is not necessarily to select a successful or unsuccessful example, but rather to demonstrate that leadership is a key element in project management, and a project cannot succeed without it. The selected case is tested in this step, with the purpose of showing how leadership skills affect projects. The case study selected is Skanska, a major international construction company.

  • Email-aware virus/malware have the ability to spread by email message by automating the infected computer's email clients or by spreading the virus/malware themselves. Mass-mailing behavior describes a situation when an infection spreads rapidly in a Microsoft Exchange environment. Trend Micro designed the scan engine to detect behavior that mass-mailing attacks usually demonstrate. The behaviors are recorded in the Virus Pattern file that is updated using the Trend Micro ActiveUpdate Servers.

  • Information about the topology and link-level characteristics of a network is critical for many applications including network diagnostics and management. However, this information is not always directly accessible; subnetworks may not cooperate in releasing information and widespread local measurement can be prohibitively expensive. Network tomographic techniques obviate the need for network cooperation, but the majority assume probing from a single source, which imposes scalability limitations because sampling traffic is concentrated on network links close to the source.

  • A reliable indicator of candidate proficiency in critical thinking and analytical writing Graduate schools are now able to receive valuable information that can be factored into admissions decisions: applicants’ scores on the GRE Writing Assessment. Since October 1999, examinees have had the opportunity to demonstrate, in a controlled testing situation, the kinds of high-level thinking and writing skills generally recognized as essential for success in many graduate programs.

  • Nuclear power approximately supplies a sixth of the world's electricity and considers as the major source of "carbon-free" energy today. With growing concerns aboutglobal warming, it is not surprising that governments and power providers around the world are considering building a substantial number of additional nuclear power plants. These plants have demonstrated remarkable reliability and efficiency with the help of extensive research work and sharing operational practical experience.

  • The authors use their decades of experience and draw upon real-world examples to demonstrate that the application of their techniques provides a basis for equipment management, uptime maximization, and reduced maintenance costs. The text explores reliability assessment techniques such as Failure Mode, Effect Analysis, and Fault Tree Analysis of commonly encountered rotating machinery. These are all highly effective techniques that the engineer can apply to maximize uptime and thereby maximize production and profitability.

  • The greatest triumph of microfinance is the demonstration that poor households can be reliable bank customers. The received wisdom at the start of the 1970s held that substantial subsidies were required to run financial institutions serving poor households in low-income countries. Government banks often shouldered the task of serving the poor, usually with a focus on farmers. However, most state-run banks were driven by political imperatives, and so they charged interest rates well below market rates and even then collected loan repayments only half- heartedly.

  • Ongoing monitoring and good data are the cornerstones of effective efforts to improve water quality. Addressing water quality challenges will mean building capacity and expertise in developing countries and deploying real-time, low-cost, rapid, and reliable field sampling tools, technologies, and data-sharing and management institutions. Resources are needed to build national and regional capacity to collect, manage, and analyze water quality data.

  • Historically, charitable trusts and foundations have sought to prevent acute social problems in the UK, using grants to demonstrate and fund interventions that improve social outcomes and reduce the number of individuals requiring crisis interventions. Trust and foundation resources are limited however – only £4.4bn9 per year compared to government budgets of £603bn10 – enabling them to demonstrate effective interventions, but not to make them available to everyone who would benefi t.

  • Magical describes conditions that are outside our understanding of cause and effect. What cannot be attributed to human or natural forces is explained as magic: super-human, super-natural will. Even in modern societies, magic-based explanations are powerful because, given the complexity of the universe, there are so many opportunities to use them. The history of medicine is defined by progress in understanding the human body – from magical explanations to measurable results.

  • One of the major challenges facing statistical machine translation is how to model differences in word order between languages. Although a great deal of research has focussed on this problem, progress is hampered by the lack of reliable metrics. Most current metrics are based on matching lexical items in the translation and the reference, and their ability to measure the quality of word order has not been demonstrated.

  • The Penn Treebank does not annotate within base noun phrases (NPs), committing only to flat structures that ignore the complexity of English NPs. This means that tools trained on Treebank data cannot learn the correct internal structure of NPs. This paper details the process of adding gold-standard bracketing within each noun phrase in the Penn Treebank. We then examine the consistency and reliability of our annotations. Finally, we use this resource to determine NP structure using several statistical approaches, thus demonstrating the utility of the corpus.

  • We present a new approach to relation extraction that requires only a handful of training examples. Given a few pairs of named entities known to exhibit or not exhibit a particular relation, bags of sentences containing the pairs are extracted from the web. We extend an existing relation extraction method to handle this weaker form of supervision, and present experimental results demonstrating that our approach can reliably extract relations from web documents.

  • Task-solving in dialogue depends on the linguistic alignment of the interlocutors, which Pickering & Garrod (2004) have suggested to be based on mechanistic repetition effects. In this paper, we seek confirmation of this hypothesis by looking at repetition in corpora, and whether repetition is correlated with task success. We show that the relevant repetition tendency is based on slow adaptation rather than short-term priming and demonstrate that lexical and syntactic repetition is a reliable predictor of task success given the first five minutes of a taskoriented dialogue. ...
