  • From its title, you can see that this book is about real-time (computing, communication, and information) systems. Rather than pausing here to define the term precisely, which we will do in Chapter 2, let us just say for now that a real-time system is required to complete its work and deliver its services on a timely basis. Examples of real-time systems include digital

  • Thus far we have discussed how to control continuous-time systems for both state-feedback and output-feedback problems. With today’s high performance real-time systems, the control algorithms developed in the continuous-time framework are typically implemented on a sampled-data system. As long as the sampling rate of the controller is high with

  • An empirical study of scale economies in the Chinese Railway System Although results are not presented here, I have estimated several additional specifications of the basic empirical test. The absence of a positive choice effect does not seem to derive from the particular weighting of the data used here—one might prefer to weight MSAs equally, or by the number of SAT-takers, rather than by their high-school-age populations—nor from the inclusion in the sample of schools with too few SAT-takers to permit accurate estimation of the school mean...

  • The scripts provided as part of this paper are sample code which can be used to base your own scripts on. These scripts have been tested on an Oracle Enterprise Linux - 2 node cluster. It is expected that they should work on all Oracle Clusterware supported platforms. Oracle Support cannot provide any direct support for these scripts. You should thoroughly test the scripts – in particular the check action of each script to ensure compatibility with your operating system.

  • SAMPLING AND RECONSTRUCTION WITH INTERSAMPLE ERROR A fundamental requirement of sampled-data systems is the sampling of continuoustime signals to obtain a representative set of numbers that can be used by a digital computer. The primary goal of this chapter is to provide an understanding of this process. The first section explores theoretical aspects of sampling and the formal considerations of signal recovery, including ideal Wiener filtering in signal interpolation. Aliasing of signal and noise are considered next in a detailed development involving a heterodyne basis of evaluation. ...

  • Internal audit technologies can greatly improve the efficiency, quality and consistency of the audit process. Data analysis software can also enhance the audit by allowing the computerised testing of entire populations of data as opposed to relying on detail testing of sample data. Internal audit infrastructure and methodologies can be developed internally or acquired from a third party. PricewaterhouseCoopers, for example, offers the TeamMate™, an integrated electronic working paper software application designed specifically for internal auditors.

  • The Natural Language Understanding Engine Test Environment (ETE) is a GUI software tool that aids in the development and maintenance of large, modular, natural language understanding (NLU) systems. Natural language understanding systems are composed of modules (such as partof-speech taggers, parsers and semantic analyzers) which are difficult to test individually because of the complexity of their output data structures.

  • In the study of nuclear structure, the fast timing technique can be used to measure the lifetime of excited states. In the paper, we have developed a new fast timing system, which is made up of two LaBr3:Ce detectors and a set of waveform sampling system. The sampling system based on domino ring sampler version 4 chip (DRS4) can digitize and store the waveform information of detector signal, with a smaller volume and higher timing accuracy, and the waveform data are performed by means of digital waveform analysis methods.

  • The purpose of this study is to quantify the floristic diversity in forests and coffee agroforests and to know the effects of different landholding sizes in Kodagu district of India's the Western Ghats. We collected the data on trees, shrubs and herbs from 50 sample plots of 0.16 ha. each and analyzed for various diversity parameters. Results revealed Shannon’s (H') was highest in coffee agroforests (3.60) compared to that of natural forest (3.32). Conversely, Simpson’s (D) values did not differ between the land-use types.
