A good performance of motion capture, which belongs to body sensor network, depends on a reasonable design of MAC protocol. The purpose of this study is to design a reliable and highly extensible protocol for applying in motion capture. The proposed MAC protocol can easily be actualized by the timer in the chip. With this MAC protocol, the network would be built quickly. One or more nodes could be...
Falls are a main cause of trauma and death. The purpose of this study is to adopt unique resultant acceleration and attitude angles to distinguish falls from activities of daily life before impact. In this study, we developed a wearable action recognition system to acquire action data. The moving average filter was employed to deal with raw data, and then complementary filter was adopted to compromise...
Virtual machine live migration has been studied for more than a decade, and this technique has been implemented in various commercial hypervisors. However, currently in the cloud environment, virtual machine migration is initiated by system administrators. Cloud customers have no say on this: They can not initiate a migration, and they do not even know whether or not their virtual machines have been...
Container technology provides a lightweight operating system level virtual hosting environment. Its emergence profoundly changes the development and deployment paradigms of multi-tier distributed applications. However, due to the incomplete implementation of system resource isolation mechanisms in the Linux kernel, some security concerns still exist for multiple containers sharing an operating system...
As the most commonly used bots in first-person shooter (FPS) online games, aimbots are notoriously difficult to detect because they are completely passive and resemble excellent honest players in many aspects. In this paper, we conduct the first field measurement study to understand the status quo of aimbots and how they play in the wild. For data collection purpose, we devise a novel and generic...
As the limited battery lifetime remains a major factor restricting the applicability of a smartphone, significant research efforts have been devoted to understand the energy consumption in smartphones. Existing energy modeling methods can account energy drain in a fine-grained manner and provide well designed human-battery interfaces for users to characterize energy usage of every app in smartphones...
Smartphone users can conveniently install a set of apps that provide Location Based Service (LBS) from markets. These LBS-based apps facilitate users in many application scenarios, but they raise concerns on the breach of privacy related to location access. Smartphone users can hardly perceive location access, especially when it happens in background. In comparison to location access in foreground,...
Cluster ensembles are approaches to combine different clustering results to obtain a robust consensus partitioning. However, many cluster ensemble methods suffer from the problem of scalability since the extensive cost of calculating co-association matrix, which makes it hard to perform cluster ensemble on large scale datasets. In this paper, we proposed a scalable co-association cluster ensemble...
Graph pattern mining is an important part of the emerging social network science, and the research of the maximum clique problem is one of the most important research branches. In the big data environment, the mass of nodes and complexity of edges in the graph set a higher requirement on the speed and accuracy of the maximum clique (MCP) study. In this paper, we present a parallel graph partitioning...
This paper firstly summarizes the present situation and existing problem in performance management and fund appropriation of community health service. And then aiming at the problems, the budget calculation model has been designed. The design ideas, research content, research methods have been introduced in the paper. Thirdly, based on results about analysis of users and business process, the paper...
The criteria to define the Middle Paleolithic in East Asia have traditionally been presence/absence of archaic Homo sapiens fossils, biostratigraphy, lithostratigraphy, the Middle-Late Pleistocene transition, and lithic technology. In this paper, we examine the use of the Middle-Late Pleistocene shift as a valid criterion for characterizing the Middle Paleolithic in East Asia. Our review indicates...
Digital content creation become an indispensable part of our lives. In addition, massive internet images provide us abundant creation material. To construct a computer-aided graphics creation system, interaction and convenience are the critical factors. With somatosensory interactive technology, we can interact with our devices in a more natural and intuitive way, and gain immersive experience at...
This paper proposes a hybrid wavelet convolution network (HWCN) which is composed of a scattering convolution component and a convolution neural component. The hierarchical end-to-end network implements sparse-coding and high-dimensional reconstruction for inverse problem through cascade convolutions. With the pre-defined scattering convolutions from nonlinear operators, the network can be tailored...
Based on information systems and government's emphasis on efficient medical service and health management, Canadian health decision support system stands in a leading position. This paper firstly researches the Canadian health decision overall development situation, clinical decision support system, public decision support system, application features etc. through the literature research method. And...
The paper aims to analyze related requirements of community health performance management, build the business model of performance management and provide references for the subsequent development of performance management information system. It applies literature research, current situation investigation, in-depth interviews, key success factors (KSF) and other analysis methods to identify core needs...
Sit-to-walk (STW) motion is essential for daily activities. Falls frequently occur, when there is impaired ability to perform STW movements. This study investigated the relationships between the dynamical characteristics of STW motion and physical functions of elderly people. 128 elderly (51 males and 77 females, above 65 years) participated in this study. Participants were instructed to perform STW...
File retrieval is a frequently adopted primitive operation for most computer users. As the dominant way for file retrieval, file navigation is yet quite inefficient. Lots Efforts have been made to either enhance the navigation interface or provide alternative. However, they all suffer from the challenge of switching users from their preferred interface to a totally unfamiliar new one. In this paper,...
Falls are a multi-causal phenomenon with a complex interaction. The aim of our research is to study the effect of multiple variables for potential risk of falls and construct an elderly fall risk assessment model based on demographics data and gait characteristics. A total of 101 subjects, whom belong to Malianwa Street, aged above 50 years old and participated in questionnaire survey. Participants...
With the rapid development of vehicular, communication and sensing technologies, intelligent transportation system(ITS) and vehicular network are widely used to improve the driving experience in the city. A key procedure of many applications in vehicular network is data gathering, a universal process to collect sensed data from sparse-distributed vehicles for further operations to provide services...
Reflections of windows or glass panes always destroy the photograph that we want to take by camera or phone. The purpose of this paper is to study and put forward a reflection removal algorithm based on GPU. The algorithm is not simply transplanted from CPU onto GPU. In order to make it adapted to the GPU architecture and programming model, we improve on the original method and the improved algorithm...
