ii ABSTRACT With the rapid growth of mobile computing and sensor technology, it is now possible to access data from a variety of sources. A big challenge lies in linking sensor based data with social and cognitive variables in humans in real world context. This dissertation explores the relationship between creativity in teamwork, and team members' movement and face-to-face interaction strength...

We tested the ability of 1and 3-month-old infants to form prototypic representations of faces. Following familiarization to four individual faces, both 1and 3-month-olds showed evidence of recognizing the individual faces but only 3-month-olds showed evidence of recognizing, and thus having mentally computed, the average of the four face stimuli. Additional experiments showed that (a) 1-month-o...

Aims: Do college students’ ratings of a professor’s teaching effectiveness suggest that a professor’s teaching improves with time? Does anything predict which instructors receive the highest ratings or improve the fastest? And, importantly, do the correlates of change differ across face-to-face and online courses? Methods: I used data from 10,392 classes taught by 1120 instructors across three ...

hospital committees play an important role in programming, organization and coordinating hospital activities. this study was conducted to evaluate hospital committees’ situation in kashan educational hospitals.  hospital committees’ meeting reports and face-to-face interview were used to data collection. there were 402 meeting reports with average 7 members attendance at the each meeting.  1292...

In this paper, we propose a new face recognition approach based on local binary patterns (LBP). The proposed approach has the following novel contributions. (i) As compared with the conventional LBP, anisotropic structures of the facial images can be captured effectively by the proposed approach using elongated neighborhood distribution, which is called the elongated LBP (ELBP). (ii) A new feat...

Faces are found generally to be perceived as thinner when viewed upside down. When a face is viewed upright, the internal features are thought to influence the perception of face shape. However, when inverted, it has been proposed that disruption to holistic processing means that these factors can no longer be used to judge the shape of a face. We show that it is not the case that an inverted f...

We present a physically-based alignment method for two point sets, which are invariant to either similarity or affine transformations. Here we assume a known correspondence between the point sets. We then employ the method to align 2D face images, find a mean-face, which is an average of all the aligned faces, and transform all face images to mean-face images for statistical face recognition. A...

On the basis of two-speaker spontaneous conversations, it is shown that the distributions of both pauses and speech-overlaps of telephone and faceto-face dialogues have different statistical properties. Pauses in a face-to-face dialogue last up to 4 times longer than pauses in telephone conversations in functionally comparable conditions. There is a high correlation (0.88 or larger) between the...

Although the rice growth response to FACE (free-air CO2 enrichment) has been widely studied and is considered important within the scientific community, few studies have attempted to examine the effects of FACE on the yield of indica rice, which is typically the parent of indica hybrids in China. The effects of FACE on the yield, yield components, biomass, N uptake and leaf photosynthesis of Ya...
