Mobile agent is a suitable paradigm to collect information from multiple sites in a distributed environment. As compare to other technologies, mobile agents can be used beneficially for Automatic Meter Reading (AMR) and to measure power quality information at each energy meter. Since meter contains embedded system, so the choice of agent platform for such an application is very important. This article investigates different methods from literature that use mobile agent paradigm for AMR process. It proposes a method that reduces the total security computation cost which is incurred in AMR process. In this method, energy meters are organized in the form of a group based upon the geographical location. In such one location energy meters perform their jobs under a security manager. In this method, the concept of local mobile agent is proposed to avoid the visit of external mobile agent to energy meters directly. Local mobile agent carries the acceptable queries from security manager and visits energy meters. This article uses mathematical modeling to represent the security computation cost incurred by each method from literature and compare it with the propose method. It is concluded that the proposed mechanism reduces the security computation cost considerably, compared to other methods.

Current active 3D range sensors, such as time-of-flight cameras, enable acquiring of range maps at video frame rate. Unfortunately, the resolution of the range maps is quite limited and the captured data are typically contaminated by noise. We therefore present a simple pipeline to enhance the quality as well as improve the spatial and depth resolution of range data in real time by up sampling the depth information with the data from high resolution video camera and utilizing a new strategy to increase the sub-pixel accuracy. Our algorithm can greatly improve the reconstruction quality, boost the resolution of the range data to that of video sensor while achieving high computational efficiency for a real-time application.

The research goal of project Cinematics and Narratives is to significantly explore approaches to the development of contemporary animation. CaN is comprised of three integrated objectives, the first is focused on developing and exploiting real-time animation and content within the context of a visual and narrative design based repository of primitives, the second explores the dynamic of context, exposition and expression, mixing our design primitives into a new dynamic form, and the third goal is to interfaces this system with an audience in such a way as to enable the system to learn from viewer reaction, where the system automatically refines the design based on the emotive input of the viewer.

Musculoskeletal disorders (MSDs) account for the largest fraction of temporary and permanent disabilities. Osteoarthritis (OA) is one of the most common MSDs which is characterized by a degeneration of articular cartilages. Understanding and preventing OA are of paramount importance in our aging yet very active society, and in this context, computer-assisted models of articulations are highly demanded by biomechanical and medical communities. To investigate the causes of some idiopathic OA, we have devised a unique comprehensive methodology to simulate musculoskeletal models of human articulations. Built from a rich variety of acquisition modalities (MRI, Motion capture, Body scanning, etc.) and innovative research, these models are fully subject-specific and account for anatomy, motion and biomechanical behavior of the articulations. This paper presents a complete overview of the methodology with medical validation and clinical case studies.

Cyber worlds fuel innovations in development and design, but whether and how to catalyze a slow-moving interplay among them remains an open question. This paper develops an argument for organizing interdisciplinary research through and around cyber worlds in order to bridge design and development by means of a collaboratory. To this end, it provides illustrative examples of plausible intersections between social sciences design agendas and broader cyber world development agendas.

Animated human body models are widely used in computer graphics applications. Creating such models requires extensive design efforts, specialized hardware such as body scanners, model databases and authoring tools. Customizing these characters or creating a virtual population with them requires multiple design efforts or powerful computers. In this paper we present a simple and robust method to create variously sized bodies based on a single template animated human body model. To achieve this, our method uses the skinning information attached to the model. By taking the positions of skeletal joints as a reference, our method automatically segments the body into its anatomical regions. Then, by using the anthropometric landmarks as parameters, the regions are deformed and the underlying skeletal structure is adapted to fit the new morphology. Our method preserves the skeleton-mesh integrity for variously sized bodies. We demonstrate our method by using a database of anthropometry measurements to generate a population of virtual humans generated from our single template model.

Commonly, surface and solid haptic effects are separated for haptic rendering. We propose a method for defining surface and solid haptic effects as well as various force fields in 3D cyber worlds containing mixed geometric models, including polygon meshes, point clouds, image-based billboards and layered textures, voxel models and functions-based models of surfaces and solids. We also propose a way how to identify location of the haptic tool in such haptic scenes as well as consistently and seamlessly determine haptic effects when the haptic tool moves in the scenes with objects having different sizes, locations, and mutual penetrations.

This study seeks to determine whether a recommendation agent’s smile and gender affect users’ trust toward the agent. We also investigate gender differences in trust toward recommendation agents of different genders and facial expressions. We present findings from a 2x2 experiment (male vs. female and smiling vs. non-smiling agents). In the context of laptop shopping, we found that on average smiling agents are perceived to be more competent than non-smiling agents and male agents are perceived to be more competent than female agents. There is a significant interaction effect between an agent's smile and gender on trust in benevolence. Specifically, male subjects tend to believe that smiling agents are more competent than non-smiling agents, while female subjects are less sensitive to the agent’s smile. Interestingly, female subjects perceive male agents to be more competent than female agents, while male subjects are almost indifferent toward the agent’s gender. Among the female subjects, trust in benevolence is highest toward a smiling male agent. Our results suggest that the gender and facial expressions of a recommendation agent should be considered when designing a virtual salesperson for online stores.
