  • As motive force of processes, heat must be transferred from one fluid to other, task that is performed by means of heat exchangers. From this point of view, heat exchangers represent an important element of thermal facilities that has substantially contributed to technical development of the society. Today it is impossible to imagine any branch of process engineering and energy technology without involvement of heat exchangers. Advanced models of these apparatus were proposed in the middle of the 18th century, while theoretical backgrounds have been completed a century later....

  • A wide range of issues related to analysis of gas turbines and their engineering applications are considered in the book. Analytical and experimental methods are employed to identify failures and quantify operating conditions and efficiency of gas turbines. Gas turbine engine defect diagnostic and condition monitoring systems, operating conditions of open gas turbines, reduction of jet mixing noise, recovery of exhaust heat from gas turbines, appropriate materials and coatings, ultra micro gas turbines and applications of gas turbines are discussed.

  • Stabilization Programs, Monetary Policy and Exchange Rate Movements in Emerging Markets Economies I use a unique data set consisting of observations on more than 300,000 metropolitan SAT takers from the 1994 cohort, matched to the high schools that students attended. The size of this sample permits accurate estimation of both peer quality and average performance for the great majority of high schools in each of 177 metropolitan housing markets. I find no evidence that the association between peer group and student performance is stronger in high-choice than in low-choice markets....

  • The main objective of this thesis is to comprehensively explore the performance of mutual funds in an emerging market. This fills one of the gaps in mutual fund literature, since studies in this region are scarce, based on the prevailing approach and survey a small number of funds over only a short period. It should not be forgotten that emerging markets are unlike developed markets in several ways. Subsequently, this thesis uses a more comprehensive dataset of mutual funds in Thailand as a case study to represent its emerging market. ...

  • In Exchange 2000, the ADC schema files were a subset of the Exchange 2000 core schema files. So although the ADC’s setup /schemaonly switch extended the schema, customers were required to perform further schema extensions using setup /forestprep. This meant longer lockdown periods for larger customers whose custom applications were sensitive to schema extensions due to the delayed nature of replications and resetting of indexed attributes. (You may refer to KB article 230662 for more information on indexed attributes)...

  • SAIs also face widely varying situations regarding the extent of the discretion that they have in the use of available audit resources. Some have almost total discretion in selecting which audits to perform and when to perform them. Others are constrained by requirements in law to perform certain audits, such as an annual audit of the execution of the state budget. Results may need to be delivered by a specified date that may consume a substantial portion of the available audit resources, at least during certain periods of the year. Nevertheless, all SAIs need...

  • In a more challenging, mature, and increasingly transparent market, this is unlikely to continue to be the case as it is increasingly possible to assembl performance records. Investors are becoming more assertive, and regulations/directives are playing an increasingly important role in the need for disclosure and accountability. The question of how manager performance is rewarded is therefore a key issue for the industry: do performance-related fees, for example, adequately distinguish between risk taking (higher beta) and genuine skill/out-performance (alpha)? ...

  • This section closes with a review of the evidence for managed port- folio performance based on the traditional measures. This discussion touches on the issues of survivorship bias and persistence in perfor- mance, among other topics. Chapter 3 discusses Conditional Performance Evaluation. Here, the idea is to measure performance accounting for the fact that the expected returns and risks for investing may vary over time depend- ing on the state of the economy. An example motivates the approach.

  • All SAIs face a situation in which the potential audits they might perform far exceed the audit resources that are available, in terms of the number and mix of skills of the audit staff. These constraints limit both the number and the type of audits that an SAI can undertake. For example, audit staff that are skilled in performing certain kinds of regularity audits may not have the skills needed to carry out certain types of performance audits and vice versa. Thus, in seeking high levels of quality, the first task of an SAI (or of...

  • An imposing barrier to entry for current plant-derived materials, and the issue most often debated, is the competitive cost situation. In many cases, the current cost of using plant-based materials is viewed as being relatively high, and not competitive with hydrocarbon-based processes. However, the cost-competitive situation contains several highly complex interactions among the key factors: value of product, cost of materials, volume of throughput, degree of processing required, and performance of the building blocks used.

  • The CGAP measure of relative macroeconomic performance is attractive for a number of reasons. First, it is based on changes in real GDP, a fundamental variable that should be highly correlated with changes in underlying welfare. Second, our measure should not be unduly sensitive to the stage of an economy’s business cycle going into the crisis. An economy that was overheating prior to 2008 would tend to have a positive unexplained component at that point in time, but it is only the unexplained component during the crisis itself that is considered in our analysis.
