The best practice for mitigating the risk of site destruction, denial, or unavailability
causing disastrous loss of critical services is to deploy redundant systems in a geographically
separated location; this practice is called geographic redundancy or georedundancy.
Enterprises deploying a geographically redundant system may spend
significantly more than when deploying a standalone configuration up front, and will
have higher ongoing operating expenses to maintain the geographically separated
redundant recovery site and system.
Robust natural language interpretation requires strong semantic domain models, "fall-soff" recovery heuristics, and very flexible control structures. Although single-strategy parsers have met with a measure of success, a multi.strategy approach is shown to provide a much higher degree of flexibility, redundancy, and ability to bring task-specific domain knowledge (in addition to general linguistic knowledge) to bear on both grammatical and ungrammatical input. A parsing algorithm is presented that integrates several different parsing strategies, with case-frame instantiation dominating. ...
Whether a terrorist attack, fibre cut, security breach, natural disaster or traffic overload, today's networks must be designed to withstand adverse conditions and provide continuous service. This comprehensive, leading-edge book reveals the techniques and strategies to help you keep enterprise data and voice networks in service under critical circumstances. You learn numerous ways to minimize single points of failure through redundancy and backups, and discover how to select the right networking technologies to improve survivability and performance....
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...
There are a number of strategies that allow an attacker to break the circle of trust and get into people’s contact lists. A
lot of social network users do not realize that their contact lists really is a circle of trust and by adding somebody they
do not know—celebrities included—they are opening their data to untrusted parties.
Some sites do not have privacy controls in place, or the ones they have do not protect all user data. Even if they do
have comprehensive privacy controls, the user is often not obligated to select who can access his/her data and is often...
One of the major challenges in TRECstyle question-answering (QA) is to overcome the mismatch in the lexical representations in the query space and document space. This is particularly severe in QA as exact answers, rather than documents, are required in response to questions. Most current approaches overcome the mismatch problem by employing either data redundancy strategy through the use of Web or linguistic resources. This paper investigates the integration of lexical relations and Web knowledge to tackle this problem.
Fault detection and diagnosis strategies always exploit some form of redundancy.
This is the capability of having two or more ways to determine some characteristic
properties (variables, parameters, symptoms) of the process, in order to exploit
more information sources for an effective detection and diagnosis action.
