Stop and go traffic that leads to oscillate traffic flow frequently is observed on congestion flow. Unexpected reasons such as lane – changing maneuvers, lower speeds of leader vehicle and moving bottleneck cause stop and go traffic and amplifying delay and environment impacts. Stop and go traffic exactly can’t be modeled by traffic models, and also car following models based on kinematic flow ...

Articulatory and perceptual aspects of fricative-stop coarticulation: a pilot study 1 Introduction This paper is concerned with the influence of a preceding fricative on the production and perception of a stop consonant. In a well-known series of experiments Repp showed that, when preceded by a fricative, an ambiguous stop acoustically halfway between /W/ and /N/ is identified differently depen...

background and aim: speech understanding almost never occurs in silence. verbal communication often occurs in environments where multiple speakers are talking. in such environments, babbling noise masks speech comprehension. consonants, in comparison to vowels, are more sensitive to noise masking. consonants provide most acoustic information needed for comprehending the meaning of the word. sin...

As an important infrastructure in the era of big data, knowledge graph can integrate and manage data resources. Therefore, construction tourism graphs with wide coverage high quality terms information from perspective tourists’ needs is effective solution to problem clutter field. This paper first analyzes current state domestic international research on constructing highlights problems associa...

This paper examines the estimation of global term weights (such as IDF) in information retrieval scenarios where a global view on the collection is not available. In particular, the two options of either sampling documents or of using a reference corpus independent of the retrieval collection are compared using standard IR test collections. In addition, the possibility of pruning term lists bas...

In this letter, we propose a novel approach using wireless sensor networks (WSNs) to enhance the safety and efficiency of four-way stop-sign-controlled (FWSC) intersections. The proposed algorithm provides right of way (RoW) and crash avoidance information by means of an intelligent WSN system. The system is composed of magnetic sensors, embedded in the center of a lane, with relay nodes and a ...

Berkeley's experiments in TREC-6 center around phrase discovery in topics and documents. The technique of ranking bigram term pairs by their expected mutual information value was utilized for English phrase discovery as well as Chinese seg-mentation. This diierentiates our phrase-nding method from the mechanistic one of using all bigrams which appear at least 25 times in the collection. Phrase ...

The present study reports a speech production experiment on children who are enrolled in a Francophone K-12 school in Southern Alberta, Canada, a predominantly English-speaking region. Students from grades 1, 3, and 5 were asked to produce a series of French words beginning with one of the six stop consonants (voiced /b/, /d/, & /g/; voiceless /p/, /t/, & /k/). Results revealed no agerelated di...

This experiment tested whether locus equation coefficients, slope, and y-intercept could serve as indices of place of articulation for obstruents sharing the same place of articulation across different manner classes. Locus equations for 22 speakers were derived from CV/t/ words with initial voiced stop /d/, voiceless aspirated stop /t/, nasal /n/, voiced fricative /z/, and voiceless fricative ...
