Advances in Internet and Smartphones are generating huge amount of customers’ opinion (or VOC: voice of customer) in the online world. VOC is very useful for marketing or product design departments to see the customers’ opinion for the products. In this paper, VOC in online review sites has been collected, stored and analyzed in order to find out what kind of factors can affect the customer pre...

This paper presents a novel approach to learning a codebook for visual categorization, that resolves the key issue of intra-category appearance variation found in complex real world datasets. The codebook of visual-topics (semantically equivalent descriptors) is made by grouping visual-words (syntactically equivalent descriptors) that are scattered in feature space. We analyze the joint distrib...

This paper presents a numerical approach for simulating volatile organic compound (VOC) emissions from dry materials. The approach has been used to examine the VOC emissions from two particleboards. The emission study for the particleboards shows that a fairly good agreement of VOC concentrations between the model prediction and experimental data can be achieved by pre-calculating the partition...

The design, fabrication and preliminary performance assessment of a new vapor sensor comprising a microfabricated optofluidic ring resonator (μOFRR) and its application to microscale gas chromatographic (μGC) detection of volatile organic compounds (VOC) are presented. The μOFRR combines vapor sensing and fluidic transport functions in a micro-fabricated whispering gallery mode (WGM) resonator....

Plants may "eavesdrop" on volatile organic compounds (VOCs) released by herbivore-attacked neighbors to activate defenses before being attacked themselves. Transcriptome and signal cascade analyses of VOC-exposed plants suggest that plants eavesdrop to prime direct and indirect defenses and to hone competitive abilities. Advances in research on VOC biosynthesis and perception have facilitated t...

Wildland fires release large amounts of particulate matter (PM), CO, S02, NO,, and Volatile Organic Carbon (VOC), which can cause serious consequence of regional and local air quality (Sandberg et al., 1999). All these components except VOC are the principal pollutants whose emissions are subject to the National Ambient Air Quality Standards (NAAQS) established by the U.S. Environmental Protect...

This study contributes to research regarding the value of children (VOC) by comparing adolescents’ VOC and their intentions to have children across 12 cultures, and by exploring the relations between these constructs at the individual and cultural levels using multilevel modeling. A total of 3,348 adolescents from 12 cultures participated in this study. On average, adolescents reported that the...

We report the use of a phenylalkyl side chain modified donor molecule to increase the open-circuit voltage (Voc) of an organic photovoltaic device. The bulky side chain is able to alter the donor/acceptor interface without interfering in the molecular packing. As a result, both Voc and device performance are improved.
