The ATIS sign language corpus
No full textSystems that automatically process sign language rely on appropriate data. We therefore present the ATIS sign language corpus that is based on the domain of air travel information. It is available for five languages, English, German, Irish sign language, German sign language and South African sign language. The corpus can be used for different tasks like automatic statistical translation and automatic sign language recognition and it allows the specific modelling of spatial references in signing space
Análise da aceitação de Sistemas Avançados de Informação ao Condutor - ATIS - em cidades brasileiras de porte médio
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Curso de Pós-Graduação em Engenharia CivilAs cidades de porte médio no Brasil, com população oscilando entre 250.000 e 500.000 habitantes, começam a experimentar alguns dos problemas de trânsito freqüentemente presentes nas grandes áreas metropolitanas. Os congestionamentos em horas de pico, situações de baixo nível de serviço em vias arteriais, com elevado consumo de combustíveis e poluição atmosférica, são alguns dos principais fatores a serem considerados. A aplicação de Sistemas Inteligentes de Transporte surge como uma das respostas possíveis para reduzir os impactos negativos do trânsito urbano, fomentar a melhoria da utilização do sistema viário e aumentar a qualidade de vida nos centros urbanos. Este trabalho objetiva analisar uma pesquisa feita com condutores, taxistas e empresas do setor de logística de Florianópolis, que utilizam intensamente o sistema viário urbano, através de técnicas de preferência revelada e preferência declarada. Foram analisadas as percepções quanto aos tipos de informação considerados mais importantes em relação ao trânsito local e a aceitação dos usuários da via quanto à utilização de serviços típicos dos Sistemas Avançados de Informação ao Condutor # ATIS, assim como sua disponibilidade em pagar por tais serviços, caso os mesmos fossem disponibilizados e cobrados, identificando inclusive, os valores aceitáveis aos entrevistados. Medium sized cities in Brazil, within a range from 250.000 to 500.000 inhabitants are starting to face some of larger metropolitan areas common traffic problems, such as congestion in peak hours, low level of service in arterials, with high fuel consumption and emission. The Intelligent Transportation Systems deployment arise as one of the possible answers do reduce the negative impacts of urban traffic and promote a better use of the road system, as well as bring a better life quality in urban centres. This work aims to analyse a research conducted with regular travelers, taxi drivers and delivery companies in Florianópolis, which use intensively the urban road system, through the use of Stated and Revealed Preference techniques. The perception about types of information considered most important regarding local traffic and acceptance about using services commonly related to Advanced Traveller Information Systems # ATIS were measured, as well as the willingness to pay for those services, if charged, identifying also the acceptable values for the respondents
SPEECH RECOGNITION IN SRI'S RESOURCE MANAGEMENT and ATIS Systems
No full textThis paper describes improvements to DECIPHER, the speech recog-nition component in SKI's Air Travel Information Systems (ATIS) and Resource Management systems. DECIPHER is a speaker-independent continuous speech recognition system based on hidden Markov model (HMM) technology. We show significant performance improvements in DECIPHER due to (I) the addition of tied-mixture I-IMM modeling (2) rejection of out-of-vocabulary speech and background noise while continuing to recognize speech (3) adapting to the current speaker (4) the implementation of N-gram statistical grammars with DECIPHER. Finally we describe our performance in the February 1991 DARPA Resource Management evaluation (4.8 percent word error) and in the February 1991 DARPA-ATIS speech and SLS evaluations (95 sentences correct, 15 wrong of 140). We show that, for the ATIS evaluation, a well-conceived system integration can be relatively robust to speech recognition errors and to linguistic variability and errors
Wheat amylase/trypsin inhibitors (ATIs): occurrence, function and health aspects
No full textInternational audienceAbstract Amylase/trypsin inhibitors (ATIs) are widely consumed in cereal-based foods and have been implicated in adverse reactions to wheat exposure, such as respiratory and food allergy, and intestinal responses associated with coeliac disease and non-coeliac wheat sensitivity. ATIs occur in multiple isoforms which differ in the amounts present in different types of wheat (including ancient and modern ones). Measuring ATIs and their isoforms is an analytical challenge as is their isolation for use in studies addressing their potential effects on the human body. ATI isoforms differ in their spectrum of bioactive effects in the human gastrointestinal (GI), which may include enzyme inhibition, inflammation and immune responses and of which much is not known. Similarly, although modifications during food processing (exposure to heat, moisture, salt, acid, fermentation) may affect their structure and activity as shown in vitro, it is important to relate these changes to effects that may present in the GI tract. Finally, much of our knowledge of their potential biological effects is based on studies in vitro and in animal models. Validation by human studies using processed foods as commonly consumed is warranted. We conclude that more detailed understanding of these factors may allow the effects of ATIs on human health to be better understood and when possible, to be ameliorated, for example by innovative food processing. We therefore review in short our current knowledge of these proteins, focusing on features which relate to their biological activity and identifying gaps in our knowledge and research priorities
Impact of traffic diversion with ATIS on travelers\u27 safety
No full textThis study investigates the potential impact of diverting traffic from freeways under incident conditions to arterials with Advanced Traveler Information Systems (ATIS). Accident prediction models are developed for freeways and arterials. Traffic safety was calculated utilizing a simple network composed of a freeway and a parallel arterial and intended to represent a realistic traffic corridor in Orlando, Flor. It was found that the overall traffic safety (expressed as the probability that no accident is observed during a specific time period) was reduced on the network as a result of diverting traffic from the freeway to the arterial up to the critical percentage of vehicles equipped with ATIS which is sufficient to congest the parallel arterial. When the percentage of vehicles equipped with ATIS exceeds the critical fraction, (Pcr), safety remained fairly unchanged since traffic equilibrium has been reached. The safety improvement on the freeway was almost constant, though. A variety of incident scenarios were simulated using a traffic diversion model, and regression techniques were used to model the network safety as a function of network and incident parameters. It was found that the increase in percentage of vehicles equipped with ATIS may reduce the overall safety on the network when traffic is diverted from freeways to less safe arterials. Since the developed accident models were based on data from the Orlando area, the results of this study may not be applicable to other locations. It is important to conduct a similar type of analysis on a more complicated large scale network to see if the impact of ATIS on traffic safety reported in this paper can be generalized. © 1998 Elsevier Science Ltd.

Wheat ATIs: Characteristics and Role in Human Disease
No full textAmylase/trypsin-inhibitors (ATIs) comprise about 2–4% of the total wheat grain proteins and may contribute to natural defense against pests and pathogens. However, they are currently among the most widely studied wheat components because of their proposed role in adverse reactions to wheat consumption in humans. ATIs have long been known to contribute to IgE-mediated allergy (notably Bakers' asthma), but interest has increased since 2012 when they were shown to be able to trigger the innate immune system, with attention focused on their role in coeliac disease which affects about 1% of the population and, more recently, in non-coeliac wheat sensitivity which may affect up to 10% of the population. This has led to studies of their structure, inhibitory properties, genetics, control of expression, behavior during processing, effects on human adverse reactions to wheat and, most recently, strategies to modify their expression in the plant using gene editing. We therefore present an integrated account of this range of research, identifying inconsistencies, and gaps in our knowledge and identifying future research needs. Note This paper is the outcome of an invited international ATI expert meeting held in Amsterdam, February 3-5 202
Potential Impact Of Advanced Traveler Information Systems (Atis) On Accident Rates In An Urban Transportation Network
No full textAdvanced Traveler Information Systems (ATIS) have the potential to improve the travel experience of individuals and, consequently, enhance the transportation system performance. ATIS will provide information that assists the traveler in selecting his destination, departure time, pre-trip route, enroute diversion, and trip chaining. One of the direct benefits of ATIS is to provide warnings on incident blockages which may encourage drivers to divert from incident routes, leading to shorter queues, fewer abrupt deceleration and safer travel conditions. ATIS may have various safety implications on the transportation network. On one side, there exists the possible distracting effect of the on-board gadget on the driver. This research is still under investigation. On the other side, congestion avoidance may improve traffic safety on the network. Thus, reducing congestion on freeways by diverting traffic to alternative arterials is expected to reduce the accident risk on freeways. However, safety on these arterials may be reduced as they become more congested. Moreover, travel conditions on arterials are not as safe as on freeways because of the higher level of traffic flow interruptions caused by side streets and traffic signals. In essence, when traffic is diverted from congested freeways to less congested arterials, the switch from higher to lower roadway hierarchy may offset the safety benefits anticipated on freeways. This paper presents a methodology for predicting changes in accident rates as a result of traffic diversion by ATIS in Orlando\u27s Transportation Network

Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
