The process monitoring and mechanics of fixed abrasive diamond wire saw machining are investigated in this study. New techniques to affix diamond particles to a steel wire core have advanced to make this process feasible for the machining of ceramics, wood, and foam materials. Developments in fixed abrasive diamond wire machining are first reviewed. Advantages of using fixed abrasive diamond wi...

Most text categorization algorithms represent a document collection as a Bag of Words (BOW).The BOW representation is unable to recognize synonyms from a given term set and unable to recognize semantic relationships between terms. In this paper, we apply the topic-model approach to cluster the words into a set of topics. Words assigned into the same topic are semantically related. Our main goal...

Most sentiment analysis approaches rely on machine-learning techniques, using a bag-of-words (BoW) document representation as their basis. In this paper, we examine whether a more fine-grained representation of documents as sequences of emotionally-annotated sentences can increase document classification accuracy. Experiments conducted on a sentence and document level annotated corpus show that...

The Bow Leg Hopper is a new type of running robot with an efficient, flexible leg. A one-legged planar prototype has been developed that passively stabilizes body attitude and is efficient enough to use on-board batteries. It is controlled by a real-time planner and has demonstrated crossing of simple artificial terrain including stepping stones and shallow stairs. The machine hops using a Bow ...

With the rapid advances in sensors of remote sensing satellites, a large number of high-resolution images (HRIs) can be accessed every day. Land use classification using high-resolution images has become increasingly important as it can help to overcome the problems of haphazard, deteriorating environmental quality, loss of prime agricultural lands, and destruction of important wetlands, and so...

We present for the ®rst time a statistical study of 350 keV ion events of a magnetospheric origin upstream from Earth's bow shock. The statistical analysis of the 50±220 keV ion events observed by the IMP-8 spacecraft shows: (1) a dawn±dusk asymmetry in ion distributions, with most events and lower intensities upstream from the quasi-parallel pre-dawn side (4 LT± 6 LT) of the bow shock, (2) hig...

In the McGurk effect, visual information specifying a speaker's articulatory movements can influence auditory judgments of speech. In the present study, we attempted to find an analogue of the McGurk effect by using nonspeech stimuli--the discrepant audiovisual tokens of plucks and bows on a cello. The results of an initial experiment revealed that subjects' auditory judgments were influenced s...

OBJECTIVES/HYPOTHESIS Analysis of auditory brainstem response (ABR) in very preterm infants can be difficult owing to the poor detectability of the various components of the ABR. We evaluated the ABR morphology and tried to extend the current assessment system. STUDY DESIGN Prospective cohort study. METHODS We included 28 preterm very low birth weight infants admitted to the neonatal intens...

Biomass gasification technology has been rapidly developed recently. But fire and poisoning accidents caused by gas leakage restrict the development and promotion of biomass gasification. Therefore, probabilistic safety assessment (PSA) is necessary for biomass gasification system. Subsequently, Bayesian network-bow-tie (BN-bow-tie) analysis was proposed by mapping bow-tie analysis into Bayesia...

Current ecologicalarchaeology,as often practiced, is too closed a system.The realization that introduced external factors may playa role in cultural changeas potently as localizedmechanismsdemands increasedattention to analytical boundaries and matters of scale.This article questions the utility and effectiveness of localizedadaptive explanations for large-scalehistorical processesand, as an il...
