In this paper, we propose a general framework for tuning component-level kinematic features using therapists’ overall impressions of movement quality, in the context of a home-based adaptive mixed reality rehabilitation (HAMRR) system. We propose a linear combination of nonlinear kinematic features to model wrist movement, and propose an approach to learn feature thresholds and weights using high-level...
Proliferation of mobile phones over the last decade has led to innovative methods for studying social behavior and friendship patterns. Our present study combined advanced mobile phone technologies, such as Bluetooth scanning and automated pushing surveys, with self-reported questionnaires to examine the social structure and psychological well-being of college students. We distributed smartphones...
A tree-based topology is often used to flood packets from the sink node in wireless sensor networks (WSNs). Therefore, flooding tree construction is an important and fundamental problem in WSNs, and has been extensively investigated in the literature. However, we note that the flooding tree construction problem in asynchronous low-duty-cycle WSNs has not been sufficiently investigated in existing...
In the future development of smart grid, wind power generation will be widely used as clean energy. Addition of nanoparticles into epoxy can improve the insulating properties compared with undoped material. However, due to the change of the material structure, trap characteristics and charge behaviors are altered as a consequence. This may cause electric field distortion and partial discharge which...
People's pursuit of benefits is the performance of demands in did. The current value theory was built on the basis of demand. In the context of economic restructuring, the concept of demands has gradually been replaced by value. This paper make a deep analysis of value theory, put forward the theory of product benefit value, based on this, developed the theoretical framework of the marketing opportunity...
This paper gives an improved alamouti 2*2 strategy in dense wireless sensor networks after analyse the model of communication between the transmitting cluster and receiving cluster. Simulation show the results of energy consumption among worst-channel, random-channel and optimal-channel. Some rules are given in the process of the simulation analyse.
In this paper we study the problem of collaboration in RF-Sensor networks, comprised of a large number of very small and low cost nodes, capable of sensing, communicating and computing. The Multi-phases Collaboration of such nodes may lead to the accomplishment of large sensing tasks, having useful applications in practice. First, we research two collaboration methods, one is no collaboration and...
