The article discusses the phenomenon of «perceptual trust» and its formation in micro intervals of time. The results of two empirical studies of trust’s perceptual estimates by human faces in various aspects of time exposure was revealed. In the first study, the following values of the time exposure used: 100,250 and 1000 ms. It is shown that the value for adequacy of perceptual trust are the highest exposure at 250 ms, and the least at 1000 ms. It is suggested that the evaluation of perceptual trust depends not only on the time of the demonstration of human facial expressions, sex, but also on the expression of human face. Wider range of exposure time values was used in the second study, 100, 300, 500, 1000 and 3000 to 1000 ms. As of stimulus images were made by representatives of persons Caucasoid, Mongoloid and Negroid racial groups. As the subjects were made by representatives of the Mongoloid racial group. The relationship between the adequacy of the perceptual trust evaluations and race of subjects and models are tested and evaluated models was revealed. The main result of the research can be considered a lack of empirical fixation unambiguous relationship between the level of trust in the person being evaluated and the duration of the perception of his face.

To represent various human facial expressions is an essential requirement for emotional bio-robots. The human expressions can convey certain emotions for communications of human beings with some muscles positions and their movements. To design and develop emotional robots, it is necessary to build a generic 3D human face model. While the geometrical features of human faces are freeform surfaces with complex properties, it is the fundamental requirement for the model to have the ability of representing both primitive and freeform surfaces. This requirement makes the Non-rational Uniform B-Spline (NURBS) are suitable for 3D human face modelling. In this paper, a new parameterised feature based generic 3D human face model is proposed and implemented. Based on observation of human face anatomy, the authors define thirty-four NURBS curve features and twenty-one NURBS surface features to represent the human facial components, such as eyebrows, eyes, nose and mouth etc. These curve models and surface models can be used to simulate different facial expressions by manipulating the control points of those NURBS features. Unlike the existing individual based face modelling methods, this parameterised 3D face model also gives users the ability to use the model imitate any face appearances. In addition the potential applications of the new proposed 3D face model are also discussed. Besides emotional bio-robots, it is believed that the proposed model can also be applied in other fields such as aesthetic plastic surgery simulation, film and computer game characters creation, and criminal investigation and prevention.

Age changes cause major variations in the appearance of human faces. Due to many lifestyle factors, it is difficult to precisely predict how individuals may look with advancing years or how they looked with "retreating" years. This paper is a review of age variation methods and techniques, which is useful to capture wanted fugitives, finding missing children, updating employee databases, enhance powerful visual effect in film, television, gaming field. Currently there are many different methods available for age variation. Each has their own advantages and purpose. Because of its real life applications, researchers have shown great interest in automatic facial age estimation. In this paper, different age variation methods with their prospects are reviewed. This paper highlights latest methodologies and feature extraction methods used by researchers to estimate age. Different types of classifiers used in this domain have also been discussed.

The Relationship

Microexpressions do exist, and they are regarded as valid cues to deception by many researchers, furthermore, there is a lot of empirical evidence which substantiates this claim. However, some researchers don’t think the microexpression can be a way to catch a liar. The author elucidates the theories predicting that looking for microexpressions can be a way to catch a liar, and notes that some data can support for the utilization of microexpressions as a good way to detect deception. In addition, the author thinks that the mixed results in the area of investigating microexpressions and deception detection may be moderated by the stake. More empirical studies which employ high-stake lies to explore the relationship between microexpressions and deception detection are needed.

The Way

The environment has always been a central concept for archaeologists and, although it has been conceived in many ways, its role in archaeological explanation has fluctuated from a mere backdrop to human action, to a primary factor in the understanding of society and social change. Archaeology also has a unique position as its base of interest places it temporally between geological and ethnographic timescales, spatially between global and local dimensions, and epistemologically between empirical studies of environmental change and more heuristic studies of cultural practice. Drawing on data from across the globe at a variety of temporal and spatial scales, this volume resituates the way in which archaeologists use and apply the concept of the environment. Each chapter critically explores the potential for archaeological data and practice to contribute to modern environmental issues, including problems of climate change and environmental degradation. Overall the volume covers four basic themes: archaeological approaches to the way in which both scientists and locals conceive of the relationship between humans and their environment, applied environmental archaeology, the archaeology of disaster, and new interdisciplinary directions.The volume will be of interest to students and established archaeologists, as well as practitioners from a range of applied disciplines.

Abstract Physicians and nurses stand with their back towards the C-arm fluoroscope when using the computer, taking things out of closets and preparing drugs for injection or instruments for intervention. This study was conducted to investigate the relationship between the type of lead apron and radiation exposure to the backs of physicians and nurses while using C-arm fluoroscopy. We compared radiation exposure to the back in the three groups: no lead apron (group C), front coverage type (group F) and wrap-around type (group W). The other wrap-around type apron was put on the bed instead of on a patient. We ran C-arm fluoroscopy 40 times for each measurement. We collected the air kerma (AK), exposure time (ET) and effective dose (ED) of the bedside table, upper part and lower part of apron. We measured these variables 30 times for each location. In group F, ED of the upper part was the highest (p < 0.001). ED of the lower part in group C and F was higher than that in group W (p = 0.012). The radiation exposure with a front coverage type apron is higher than that of the wrap-around type and even no apron at the neck or thyroid. For reducing radiation exposure to the back of physician or nurse, the wrap-around type apron is recommended. This type of apron can reduce radiation to the back when the physician turns away from the patient or C-arm fluoroscopy.

The Relationship

Empirical studies largely support the continuity hypothesis of dreaming. The present study investigated the frequency and emotional tone of dreams of truck drivers. On the one hand, the findings of the present study partly support the continuity regarding the time spent with driving/being in the truck and driving dreams and, on the other hand, a close relationship was found between daytime mood (feelings of stress, job satisfaction) and dream emotions, i.e., different dream characteristics were affected by different aspects of daytime activity. The results, thus, indicate that it is necessary to define very clearly how this continuity is to be conceptualized. The approach of formulating a mathematical model (cf. [1]) should be adopted in future studies in order to specify the factors and their magnitude in the relationship between waking and dreaming.

The FPN is an important part in CCD noise. The positions of the FPN in CCD are fixed, and the magnitude follows some rules. Through measuring the positions and magnitude of the FPN beforehand, we could eliminate the FPN in the image processing afterward. The causes and forms of the FPN are analyzed. The FPN of the science grad CCD Alta U9000 is introduced. The relationship between the FPN of U9000 and the exposure time is determined with the shutter closed. And the FPN of images taken in another experiment is eliminated. The experiment results well.

Recent discussions of the history of American communism have generated a good deal of controversy. A youthful generation of “new social historians” has combined with veterans of the Communist party to produce a portrait of the Communist experience in the United States which posits a tension between the Byzantine pursuit of the “correct line” at the top and the impulses and needs of members at the base trying to cope with a complex reality. In the words of one of its most skillful practitioners, “the new Communist history begins with the assumption that … everyone brought to the movement expectations, traditions, patterns of behavior and thought that had little to do with the decisions made in the Kremlin or on the 9th floor of the Communist Party headquarters in New York.” The “new” historians have focused mainly on the lives of individuals, the relationship between communism and ethnic and racial subcultures, and the effort to build the party's influence within particular unions and working-class constituencies. Overall, the portrait has been critical but sympathetic and has served to highlight the party's “human face” and the integrity of its members.
