  • Clarissa, an experimental voice enabled procedure browser that has recently been deployed on the International Space Station (ISS), is to the best of our knowledge the first spoken dialog system in space. This paper gives background on the system and the ISS procedures, then discusses the research developed to address three key problems: grammarbased speech recognition using the Regulus toolkit; SVM based methods for open microphone speech recognition; and robust side-effect free dialogue management for handling undos, corrections and confirmations. ...

  • The purpose of this handbook is to provide in one location detailed, up-to-date information on various facets of mass measurement that will be useful to those involved in mass metrology at the highest level (at national standards laboratories, for example), in science and engineering, in industry and commerce, in legal metrology, and in more routine mass measurements or weighings. We have pursued clarity and hope that we have in some measure succeeded.

  • The aim of the study was to investigate the crystallization kinetics and solidification behaviour of Fe60Co8Mo5Zr10W2B15 bulk glass forming alloy. The solidification behaviour in near-equilibrium and non-equilibrium cooling conditions was studied. The eutectic and peritectic reactions were found to exist in the solidification sequence of the alloy. The bulk metallic glass formation was achieved by using two methods: quenching from the liquid state and quenching from the semi-state.

  • In 1990, preimplantation genetic diagnosis (PGD) was introduced as an experimental procedure to genetically screen human embryos during an in vitro fertilization (IVF) cycle (1,2). More than a decade later, PGD has become an established clinical procedure in assisted reproductive technologies with over 6500 PGD cycles performed worldwide, resulting in the birth of well over 1000 healthy babies and a pregnancy rate per transfer of approximately 24% (3).

  • The majority of studies addressed in this chapter reflect research findings that provide "best bets" for preventing sexual risk-taking behaviors. These derive from longitudinal, multivariate analyses of reproductive health topics. In addition, a synthesis of programs that have had rigorous experimental designs help provide information on "what works" and what doesn't work within the program field.

  • Some recent experiments support a claim that the observed differences between willingness to pay and willingness to accept are related to experimental procedures and have nothing to do with preference asymmetries (Plott and Zeiler (2003)) or are eliminated by trading experience (List, 2003). Older people are often presumed to be more conservative and more likely to avoid risk. If this is true, then it would seem natural to expect loss avoidance to be stronger in the older populations.

  • The reactions of the flavin semiquinone generated by laser-induced stepwise two-photon excitation of reduced flavin have been studied previously (El Hanine-Lmoumene C & Lindqvist L. (1997) Photochem Photobiol66, 591–595) using time-resolved spectroscopy. In the present work, we have used the same experimental procedure to study the flavin semiquinone in rat kidney long-chain hydroxy acid oxidase and in the flavodehydrogenase domain of flavocytochrome b2 FDH

  • Tumor suppressor protein p53 plays a central role in maintaining genomic integrity [1–3]. In unstimulated cells p53 is maintained at very low levels but in response to DNA damage or other stress stimuli, such as hypoxia or activation of oncogenes, p53 becomes stabilized and accumulates in the cell [4, 5]. p53 can exert its tumor suppressor function in different ways (Fig. 1.1).

  • From the early 1970s to mid-1990s, positron emission tomography (PET) as a diagnostic imaging modality had been for the most part used in experimental research. Clinical PET started only a decade ago. 82Rb-RbCl and 18F-Fluorodeoxyglucose were approved by the U.S. Food and Drug administration in 1989 and 1994, respectively, for clinical PET imaging. Reimbursement by Medicare was approved in 1995 for 82Rb-PET myocardial perfusion imaging and for 18F-FDG PET for various oncologic indications in 1999. Currently several more PET procedures are covered for reimbursement....

  • Fuel Injection is a key process characterising the combustion development within Spark- Ignition (SI) and Compression Ignition (CI) Internal Combustion Engines (ICEs). Fuel Injection and Spray Behaviour in fact largely control the fuel-air mixing, combustion process efficiency, stability, the production of noxious species, the radiated noise, etc.The proper design of the fuel injection system requires the employment of both experimental and numerical techniques, sometimes coupled for optimisation procedures....
