  • Oracle Real Application Clusters (RAC) harnesses the processing power of multiple, interconnected servers on a cluster; allows access to a single database from multiple servers on a cluster, insulating both applications and database users from server failures, while providing performance that scales out on-demand at low cost; and is a vital component of grid computing that allows multiple servers to access a single database at one time. Oracle Database 11g also includes Automated Storage Management (ASM) and Oracle Clusterware.

  • For AE FRP vessels are used as a primary means of assessment. It usually does not incorporate with strain gauge device or other sensor devices. This may be partly due to the nature of damage in FRP vessels and the resulting brittle failure mode. In the structure local damage can lead to catastrophic failure without warning clearly detected. one of the important advantages of sound emissions in this industry is the ability to assess the importance damage.

  • Reliability engineering and predictive maintenance have two major objectives: preventing catastrophic failures of critical plant production systems and avoiding deviations from acceptable performance levels that result in personal injury, environmental impact, capacity loss, or poor product quality. Unfortunately, these events will occur no matter how effective the reliability program. Therefore, a viable program also must include a process for fully understanding and correcting the root causes that lead to events having an impact on plant performance....

  • In addition, the fact that there have been few studies investigating the efficacy of conversational implicature to enhance Japanese high school students’ communicative competence was another cause for me to start this research. Though some experimental studies have been done (see Bouton,1992; Broersma, 1994; Kubota, 1995; and Taguchi, 2007), the subjects of their research were university students and immigrants. Few people seem to have examined students’ development of communicative ability in Japanese high school.

  • Safety training will be presented by the Design-Builder’s Safety Manager. Safety training includes orientation training, daily “Short course” field toolbox meetings, a monthly “Stand down” safety meeting, and as-needed training such as railroad safety training. Design quality training is presented by the DQAM. There may be different versions: one for the management staff to understand the quality requirements of design; another is for design staff to develop a detailed understanding of the quality process.

  • To quantify the impact of luck on mutual fund performance, we use the False Discovery Rate (F DR) introduced by Benjamini and Hochberg (1995) in the statistical literature. The F DR measures the proportion of lucky funds among the funds with significant estimated alphas. We extend this methodology by developing a new approach which allows us to separately compute the F DR among funds with significant positive estimated alphas (called hereafter the best funds) and funds with significant negative estimated alphas (called hereafter the worst funds)....

  • Literature: When reading literature, students must demonstrate their capacity to pay special attention to the choices authors make about words and structures. Many literary effects depend on the order in which events unfold and the specific details used to describe characters and actions. Since these same strategies—order and use of detail—are equally critical in understanding the most demanding informational texts, reading literature helps students comprehend what they read in science, history and other subjects.

  • The Center for Chemical Process Safety (CCPS) was established in 1985 by the American Institute of Chemical Engineers (AIChE) for the express purpose of assisting the Chemical and Hydrocarbon Process Industries in avoiding or mitigating catastrophic chemical accidents. To achieve this goal, CCPS has focused its work on four areas: • establishing and publishing the latest scientific and engineering practices (not standards) for prevention and mitigation of incidents involving toxic and/or reactive materials,...

  • Finally, the requirements that a fund has to fulfill in order to be included in the SIF's listing of SRI funds are not stringent. For example, a fund could be on the list just by having a formal policy of excluding companies with interests in the tobacco business. If the constraints that SRI (as defined in our data set) imposes on fund managers are minor, the performance of SRI mutual funds should not be expected to be lower than that of conventional funds. It is important to highlight that the estimated performance differences between SRI and conventional funds cannot...

  • Audit Committees are no more than a part of those defences. But we believe that they are a most important part and that there could be considerable benefits if their role were clarified and enhanced. This would be beneficial not only in increasing the level of assurance against catastrophic failure and gross malfeasance; it would also offer improvements on a wider front, raising the overall standard of corporate governance for all companies that implement our guidance.

  • There are four major categories of catastrophic failure which exists in the boiler itself. 1. Melt down. This is a result of the heating surface metal reaching its melting point. It is a result of the boiler operating on very low water conditions. This by itself will not cause an explosion but will do major damage to the boiler and create a dangerous situation which could lead to an explosion.

  • Make the roles of the project team members clear from the beginning. Projects can work as group democracies, but it usually helps to have a project leader who is responsible for organisation and for seeing that deadlines are kept. Project team members will often do a lot of extra work, but putting too much stress will often be counter-productive in the long run.

  • All these changes have a huge impact on the way the database query optimizer works. Having user-defined functions deep in- side the query plans makes cost estimation problematic. Having real data with high skew has always been problematic, but in this new world the relational operators are just the outer loop of a non- procedural program that should be executed with the least cost and in parallel. Cost-based static-plan optimizers continue...

  • All electrochemical power sources deteriorate over time. In contrast to many other technologies, however, the deterioration tends to be slow and predictable, and catastrophic failure is rarely observed. Owing to the gradual decline in performance, it is important to have a clear definition of what constitutes end of lifetime. The following terms are used to denote different aspects of lifetime (see Figure 1)

  • Stability is a basic concern in both design and analysis of load-carrying systems and constitutes a major topic in the field of engineering science and mechanics. Since structural instability may lead to catastrophic failure of engineering structures, stability requirements must be satisfied besides requirements related to material failure. Knowledge on stability is of great importance in the areas of Civil Engineering, Mechanical Engineering and Aerospace Engineering; and all these disciplines have their own literature related to the subject....
