  • We present an LFG-DOP parser which uses fragments from LFG-annotated sentences to parse new sentences. Experiments with the Verbmobil and Homecentre corpora show that (1) Viterbi n best search performs about 100 times faster than Monte Carlo search while both achieve the same accuracy; (2) the DOP hypothesis which states that parse accuracy increases with increasing fragment size is confirmed for LFG-DOP; (3) LFGDOP's relative frequency estimator performs worse than a discounted frequency estimator; and (4) LFG-DOP significantly outperforms TreeDOP if evaluated on tree structures only.

  • This diagram illustrates the Physical layer (Layer 1) of the OSI model. The Physical layer is responsible for the ultimate transmission of data over network communications media. It operates with data in the form of bits that are sent from the Physical layer of the sending (source) device and received at the Physical layer of the destination device. Ethernet cabling, Token Ring network technology and SCSI all function at the Physical layer of the OSI model. Hubs and other repeaters are standard network devices that function at the Physical layer.

  • Geostatistics is expanding very fast: concept- and technique-wi se. Keeping in view the importance of the subject, it was thought approp riate to bring out the second edition of this book. In this process, Chapter I has been expanded incorporating more detail s on sampling and sampling designs. In Chapter 2, a section on simulation has been introduced with emphasis on Monte-Carlo simulation with worked out examples. In Chapter 5, a procedure to compute variogram in the case of irregular grid has been outlined. Minor modific ations have been made in all other chapters.

  • Does this mean that differences in genetic diversity levels will have predictable ecological consequences? The answer is no, because only one portion of genetic diversity is connected to ecological factors, i.e. adaptation. Ecological adaptation is a significant factor for example, in range expansion of plant species. Plants with different genotypes conferring the highest levels of fitness are expected to survive and reproduce better, shifting the gene pool over time towards higher frequencies of the alleles making up the more successful genotypes (Ward et al., 2008).

  • This book is concerned with Ultra-Low-Frequency (ULF)-electromagnetic waves observed on the Earth and in Space. These are so-called geomagnetic variations or pulsations. Alfv´en’s discovery related to the influence of the strong magnetic field on the conducting fluids (magnetohydrodynamics) led to development of the concept that the ULF-waves are magnetospheric magnetohydrodynamic (MHD)-waves. MHD-waves at their propagation gather information about the magnetosphere, ionosphere, and the ground. There are two applied aspects based on using the ULF electromagnetic oscillations.

  • In the previous sub-section we have described the evolution of yields and interest rate spreads in 2002 using weekly data. If the information revealed by policy events is processed efficiently in capital markets, it may nevertheless be necessary to look at higher frequencies to detect any impact of fiscal policy events. In this section we therefore focus more carefully on specific events using daily data. As an illustration, we select two periods for a closer look.

  • Assume a policy with a $2 million premium that reimburses the policyholder when aggregate losses for the calendar year exceed $10 million. Assume that the losses covered by the policy are generally low severity/high frequency, with minimal catastrophe potential (i.e., the policy is meant to cover mostly pricing risk, not large loss risk). Also assume that the expected losses are $8 million, and that the expected losses normally occur evenly throughout the year. After one quarter, losses would have to be 500% of expected for attachment to occur.

  • We characterize precisely the possible rate of decay of the anti-analytic half of a trigonometric series converging to zero almost everywhere. 1. Introduction 1.1. In 1916, D. E. Menshov constructed an example of a nontrivial trigonometric series on the circle T ∞ (1) n=−∞ c(n)eint which converges to zero almost everywhere (a.e.). Such series are called nullseries. This result was the origin of the modern theory of uniqueness in Fourier analysis, see [Z59], [B64], [KL87], [KS94]. Clearly for such a series |c(n)|2 = ∞.

  • Normally the frequency divider designed by Boole algebra and to design a frequency divider with any divide factor, we have to repeat all over again every design step as the same. So to avoid of wasting time and money, instead of using traditional Boole algebra in digital technical we replace it by mathematical models in high algebra. And because of that we can design frequency dividers use computer. 1. Modeling of function circuit

  • Age-related hearing loss or presbycusis is mainly caused by changes in the inner ear. However, your genes and loud noises (such as from rock concerts or music headphones) may play a large role. Initially there is difficulty in hearing high-frequency sounds, such as someone talking. As hearing gets worse, it may become difficult to hear sounds at lower pitches. Hearing aids Telephone amplifiers and other assistive devices may be helpful. A cochlear implant (Surgery) may be recommended for certain women with very severe hearing loss.

  • Wireless communications offer organizations and users many benefits such as portability and flexibility, increased productivity, and lower installation costs. Wireless technologies cover a broad range of differing capabilities oriented toward different uses and needs. Wireless local area network (WLAN) devices, for instance, allow users to move their laptops from place to place within their offices without the need for wires and without losing network connectivity. Less wiring means greater flexibility, increased efficiency, and reduced wiring costs.

  • Accordingly, for the purpose of impact assessment, it was decided not to use response functions from daily mortality time-series studies to estimate the excess annual mortality but the change in the long-term mortality rates associated with ambient air pollution. 5 Contrary to the exposure function which is assumed to be the same for all countries, the health outcome frequency (frequency with which a health outcome appears in the population for a defined time span) may differ across countries. These differences may result from a different age structure or from other factors (i.e.

  • Since its creation in 1987 Perl has become one of the most widely used programming languages. One measure of this is the frequency with which various languages are mentioned in job adverts. The site www.indeed.com monitors trends: in 2010 it shows that the only languages receiving more mentions on job sites are C and its offshoots C++ and C#, Java, and JavaScript.

  • Humanb2 -glycoprotein I (b2 GPI), also known as apolipo-protein H, has been implicated in haemostasis and the pro-duction ofanti-phospholipid antibodies. There is a wide range ofinterindividual variation in b2GPI plasma levels that is thought to be under genetic control, but itsmolecular basis remains unknown. To understand the genetic basis of b2GPI variation, we analyzed the 5¢ flanking region ofthe b2GPIgene for mutation detection by DHPLC and identi-fied a point mutation at the transcriptional initiation site ()1CfiA) with a carrier frequency of 12.1%. ...
