TL;DR: The architecture and several features of the AR prototype system, built around a stereoscopic head-mounted display of the video-see-through variety, are described, which provides a compelling AR perception.
Abstract: Augmented Reality is an emerging technology that seeks to enhance a user's view by overlaying graphical information. We developed a prototype AR system geared for medical applications. It is built around a stereoscopic head-mounted display of the video-see-through variety. The newest generation of this prototype system exhibits high performance on a standard PC platform. Stereoscopic video images are augmented with medical graphics in real-time at 30 frames per second and with XGA (1024× 768) resolution. The system provides a compelling AR perception: the graphics appears firmly anchored in the scene--there is no time lag between video and graphics or any apparent jitter of the graphics. With the head-mounted display, the user has a natural and direct access to understanding the 3D structure of the scene, based on both stereo and kinetic depth cues. In the present paper, we describe in detail the architecture and several features of the AR prototype system. Head tracking is accomplished with a single-camera system, with the dedicated tracker camera placed on the head-mounted display. This configuration is the foundation of achieving a high-accuracy graphics overlay. We are now exploring the use of the prototype system for a variety of medical applications. This paper gives an overview over the pre-clinical tests that we have performed for interventional guidance. Overall, the feedback has been very positive and encouraging, and we are continuing to work towards realizing the clinical potential of the technology.

TL;DR: In this paper, a real-time monitoring and analysis of the wireless network nodes, routing, coordinator to collect the information of the spectrum, the noise, the network of communication protocol, the EPC RFID data communication protocol and the states, low power states.
Abstract: The Internet of things needs using the self-configuring wireless sensors network to interconnect all things. Using a internet of things analyzer Architecture and methods, we can real time monitor and analysis the wireless network nodes, routing, coordinator to collect the information of the spectrum, the noise, the network of communication protocol, the EPC RFID data communication protocol and the states, low power states . . . . The architecture and methods will help build the high reliability, long battery life, green Internet of things and wireless sensors network.

TL;DR: A novel component-based, service-oriented framework for distributed metacomputing that emphasizes lightweight software infrastructures that maintain minimal state, and interface to current and emerging distributed computing standards is described.
Abstract: A novel component-based, service-oriented framework for distributed metacomputing is described. Adopting a provider-centric view of resource sharing, this framework emphasizes lightweight software infrastructures that maintain minimal state, and interface to current and emerging distributed computing standards. In this model, resource owners host a software backplane onto which owners, clients, or third-party resellers may load components or component-suites that deliver value added services without compromising owner security or control. Standards-based descriptions of services facilitate publication and discovery via established schemes. The architecture of the container framework, design of components, security and access control schemes, and preliminary experiences are described in this paper.
