  • In this paper, a method to reproduce realistic driving feeling and improve the returnability of steer-by-wire systems (SBW) is proposed by measuring the roadwheel motor's current directly. The key contribution presented here is a novel method to recreate the driving feeling in term of force feedback with simpie and cheap current sensors. A current sensor is used to fully measure the steering torque on the rack of steering mechanism. This measured steering torque therefore, includes the overall effects of road conditions, aligning moments, tire properties and so on.

  • Presence of epigenetic marks enables cells with the same genotype have potential to display different phenotypes and differentiate into many cell-types with different functions, and responses to environmental and intercellular signaling. For example, DNA methylation is essential for the process of imprinting. Imprinted genes are expressed from only one parental allele. This mono-allelic gene expression is directed by epigenetic marks established in the mammalian germ line and a single mutation, either genetic or epigenetic, can cause disease.

  • To accurately estimate energy savings attributable to the ENERGY STAR program, and target future efforts, current data are needed on the extent to which each type of office equipment is turned off or successfully enters low power mode when idle. Combined with measurements of the energy used in each power state, we can estimate typical unit energy consumption (UEC), which, combined with number of units currently in use, provides an estimate of total energy use, and program savings (Webber, Brown et al. 2002). In our ongoing technical support of ...

  • An important goal of computational linguistics has been to use linguistic theory to guide the construction of computationally efficient real-world natural language processing systems. At first glance, generalized phrase structure grammar (GPSG) appears to be a blessing on two counts. First, the precise formalisms of GPSG might be a direct and fransparent guide for parser design and implementation. Second, since GPSG has weak context-free generative power and context-free languages can be parsed in O(n ~) by a wide range of algorithms, GPSG parsers would appear to run in polynomial time.

  • Research, development and industrialisation of renewable energy are currently moving at a rapid pace worldwide. Biofuels play significant roles in decarbonisation of our future energy needs and act to mitigate deleterious impacts of greenhouse gas emissions. Liquid transportation biofuels (bioethanol and biodiesel) now represent key contributors to the bioenergy portfolios in many countries.

  • The development of robust accuracy assessment methods for the validation of spatial data represents a difficult challenge for the geospatial science community. The importance and timeliness of this issue are related directly to the dramatic escalation in the development and application of spatial data throughout the latter 20th century. This trend, which is expected to continue, will become increasingly pervasive and continue to revolutionize future decision-making processes.

  • Taxation of e-commerce is a major concern for international agencies and tax authorities worldwide. In its most advanced form, e-commerce allows unidentified purchasers to pay obscure vendors in ‘electronic cash’ for products that are often goods, services and licences all rolled into one. A payee may be no more than a computer that can take up ‘residence’ anywhere; national boundaries are of no consequence whatsoever.

  • The tax rules of the United States and of foreign countries affect multinational corporations in a variety of ways. Researchers at the National Bureau of Eco- nomic Research have been studying the impact of taxation on multinational corporations for several years. From time to time, the results of this research have been presented at NBER conferences and subsequently published in NBER volumes. The papers in the current volume, which were presented at such a conference in January 1994, were the result of studies during the previ-...

  • Thus, to date, women have not featured prominently as business leaders within the veterinary profession, nor have they been perceived as potential entrepreneurs or innovators. This point is particularly important, because based on what we know about women and business ownership/entrepreneurship generally (see, for example, Brush, 1997; Brush, Carter, Gatewood, Green & Hart, 2001; Henry & Treanor, 2010), it is unlikely that current levels of veterinary entrepreneurship will be maintained or, indeed, increased in a female dominated veterinary sector. ...

  • In 1989, Hodge et al. published two papers in the Journal of Urology (Hodge et al., 1989a and 1989b). The first paper described directed transrectal prostate biopsies of palpable abnormalities, 90% of which had corresponding hypoechoic lesions on ultrasound (Hodge 1989a). Additional biopsies were also taken of isoechoic areas of the peripheral and central zones. These biopsies were not systematic and they were found to be positive in 66% of cases. The second article was a landmark paper which marked the start of the modern era of prostate needle biopsy (Hodge et al., 1989b).

  • Thermal noise from optical coatings is a growing area of concern, and overcoming limits to the sensitivity of high-precision measurements by thermal noise is one of the greatest challenges faced by experimental physicists. In this timely book, internationally renowned scientists and engineers examine our current theoretical and experimental understanding. Beginning with the theory of thermal noise in mirrors and substrates, subsequent chapters discuss the technology of depositing coatings and state-of-the-art dielectric coating techniques used in precision measurement.

  • Many harms flow across the ever-more porous sovereign borders of a globalizing world. These harms expose weaknesses in the international legal regime built on sovereignty of nation states. Using the Trail Smelter arbitration, one of the most cited cases in international environmental law, this book explores the changing nature of state responses to transboundary harm. Taking a critical approach, the book examines the arbitration’s influence on international law generally and international environ- mental law specifically.
