Face detection is a key problem in building automated systems that perform face recognition. A very attractive approach for face detection is based on multiresolution images (also known as mosaic images). Motivated by the simplicity of this approach, a rule-based face detection algorithm in frontal views is developed that extends the work of G. Yang and T.S. Huang. The proposed algorithm has be...

This paper presents feature level fusion approach using multi resolution Curvelet transform for face and palm biometrics.In this paper feature extraction has been done by taking the curvelet transform of bit quantized images.The curvelet coefficient thus obtained acts as feature set for classification.The five sets of coefficients from five different versions of images are used to train five SV...

UNLABELLED When selecting a respirator, it is important to understand how employees' motor, visual and cognitive abilities are impacted by the personal protective equipment. This study compares dust, powered-air-purifying and full-face, negative-pressure respirators. Thirty participants performed three varied tasks. Each participant performed each task without a respirator and while wearing the...

This paper explores the role of gaze in coordinating turn-taking in mixed-initiative conversation and specifically how gaze indicators might be usefully modeled in computational dialogue systems. We analyzed about 20 minutes of videotape of eight dialogues by four pairs of subjects performing a simple face-to-face cooperative laboratory task. We extend previous studies by explicating gaze patte...

The present study examined the role of media use in adolescents’ cyberbullying behaviors. Following previous research, we propose a Cyclic Process Model of face-to-face victimization and cyberbullying through two mediating processes of anger/frustration and antisocial media content. This model was tested utilizing a cross-sectional design with adolescent participants (N = 892). Exposure to anti...

In this paper firt of all we introduce a generalization of torsion freeness of acts over monoids, called -torsion freeness. Then in section 1 of results we give some general properties and in sections 2, 3 and 4 we give a characterization of monoids for which this property of their right Rees factor, cyclic and acts in general  implies some other properties, respectively.

Since crisis management training requires extensive resources, a computer-simulated environment where communication plays a crucial role, can be an effective and efficient way to complement real-life training. With the aim of designing a simplified communication interface for a training simulator, this paper analyzes the complex communication network of crisis management, based on observations ...

HIV/AIDS is a serious challenge to economic development. Increasing mortality and morbidity reduce living standards directly and have repercussions that affect all areas of the economy. Individuals and households face increasing risks, both directly through the risk of infection, and indirectly as formal and informal social insurance mechanisms are eroded. Companies face productivity losses and...

We report on a series of economic decision-making experiments exploring how individuals make lifecycle consumption and saving plans when they face different income profiles. We find that for every lifecycle income profile that we consider, subjects on average over-consume in the early periods of their lives and under-consume in later periods of their lives relative to the conditional optimum an...
