  • HVAC systems are sized to satisfy a set of design conditions, which are selected to generate a maximum load. Because these design conditions prevail during only a few hours each year, the HVAC equipment must operate most of the time at less than rated capacity. The function of the control system is to adjust the equipment capacity to match the load.

  • When a fiber-optic link is neither practical nor feasible, under the above scenario, wireless optical communications (WOC) becomes a real alternative, since it allows to transfer data with high-bandwidth requirements with the additional advantages of wireless systems (Arimoto, 2010; Ciaramella et al., 2009; Sova et al., 2006). Moreover, a wireless optical communication system offers, when compared with RF technology, an intrinsic narrower beam; less power, mass and volume requirements, and the advantage of no regulatory policies for using optical frequencies and bandwidth....

  • Onsite treatment of wastewater and onsite dispersal of treated wastewater is not a new concept. Throughout the history of civilization in this country and other places in the world, onsite wastewater systems have been and will be an integral part of the overall wastewater management infrastructure. Onsite wastewater systems are here to stay and the U.S. Environmental Protection Agency (EPA) views adequately managed onsite systems as a cost-effective and long-term option for meeting public health and water quality goals, particularly in less densely populated areas....

  • An increasing number of telephone services are offered in a fully automatic way with the help of speech technology. The underlying systems, called spoken dialogue systems (SDSs), possess speech recognition, speech understanding, dialogue management, and speech generation capabilities, and enable a more-or-less natural spoken interaction with the human user. Nevertheless, the principles underlying this type of interaction are different from the ones which govern telephone conversations between humans, because of the limitations of the machine interaction partner.

  • Most flat-panel monitors use liquid crystal display (LCD) technology. Passive matrix LCD uses a transistor for each row and column of pixels: less expensive, narrow viewing angle, submarining (animated graphics blurry) Active matrix LCD uses a transistor for each pixel on the screen: expensive, wider viewing angle, faster refresh Thin-film transistor (TFT) displays use multiple transistors for each pixel.

  • Since the time of Newton the basic structure of the solar system and the laws that govern the motions of the bodies within it have been well understood. One central body, the Sun, containing most of the mass of the system has a family of attendant planets in more-or-less circular orbits about it. In their turn some of the planets have accompanying satellites, including the Earth with its single satellite, the Moon. With improvements in telescope technology, and more recently through space research, knowledge of the solar system has grown apace.

  • For languages whose character set is very large and whose orthography does not require spacing between words, such as Japanese, tokenizing and part-of-speech tagging are often the difficult parts of any morphological analysis. For practical systems to tackle this problem, uncontrolled heuristics are primarily used. The use of information on character sorts, however, mitigates this difficulty. This paper presents our method of incorporating character clustering based on mutual information into DecisionTree Dictionary-less morphological analysis.

  • Strength reduction leads to a reduction in hardware complexity by exploiting substructure sharing and leads to less silicon area or power consumption in a VLSI ASIC implementation or less iteration period in a programmable DSP implementation. Strength reduction enables design of parallel FIR filters with a lessthan-linear increase in hardware.

  • The global burden of neuropsychiatric disorders is substantial. When measured by years lived with disability and years lost due to premature death in disability-adjusted life years (DALYs), psychiatric and neurological conditions accounted for 13% of the global burden of disease in 2002 (WHO, 2004). Despite the huge burden of mental illness, few human and financial resources are directed towards mental health care. Mental health spending in many countries of the world is less than 1% of the health budget, and the number of mental health professionals is grossly inadequate (WHO, 2005a)....

  • Certain jobs have a notorious reputation for causing cancer. Asbestos and lung cancer and mesothelioma, a cruel and invariably fatal cancer. Vinyl chloride exposure and liver cancer. Work in the rubber industry and bladder cancer. And nasal cancer and work with wood or leather dust. But many other jobs have a risk which is just as real, but which is less commonly known. The man who delivered the milk to an asbestos factory in Canada got cancer as a result. Nurses handling cancer drugs can be at risk.

  • Small firms also tend to fill niches in the labor market that are underserved (often have high rates of unemployment, for example). Small firms employ higher shares of Hispanics than large firms (65.9 percent of Hispanics work for firms with fewer than 500 employees). 9 And compared with large firms, small firms also employ higher shares of individuals with low educational attainment—a high school degree or less (63.2 percent); high school-aged workers (63.8 percent); individuals 65 or older (64.6 percent); disabled workers (59.4 percent); and rural workers (64.3 percent). ...

  • In this paper, we will describe ODIE, the On-Demand Information Extraction system. Given a user’s query, the system will produce tables of the salient information about the topic in structured form. It produces the tables in less than one minute without any knowledge engineering by hand, i.e. pattern creation or paraphrase knowledge creation, which was the largest obstacle in traditional IE. This demonstration is based on the idea and technologies reported in (Sekine 06).

  • We present experimental evidence that providing naive users of a spoken dialogue system with immediate help messages related to their out-of-coverage utterances improves their success in using the system. A grammar-based recognizer and a Statistical Language Model (SLM) recognizer are run simultaneously. If the grammar-based recognizer suceeds, the less accurate SLM recognizer hypothesis is not used.

  • Linux has come a long way in a short time. Computing itself is still relatively young by any standard; if the era of modern computing started with the invention of the microchip, it’s still less than 50 years old. But Linux is a youngster compared even to this; it has been around for only 15 of those years. In that brief time span, a student’s personal project has grown to where it now runs many computers throughout the world.

  • The apparent division between cultural and linguistic approaches to translation that characterized much translation research until the 1980s is disappearing, partly because of shifts in linguistics that have seen that discipline take a more overtly cultural turn, partly because those who advocated an approach to translation rooted in cultural history have become less defensive about their position.
