A commodity I/O device has no support for virtualization. A VMM can assign such a device to a single guest with direct, fast, but insecure access by the guest’s native device driver. Alternatively, the VMM can build virtual devices on top of the physical device, allowing it to be multiplexed across VMs, but with lower performance. We propose a technique that provides an intermediate option. In ...

background: obesity is a major problem in both developed and underdeveloped countries. the aim of this study is to investigate the effects of a physical education program (pep) on promoting health belief model (hbm) scores, increasing physical activity (pa), and reducing obesity among iranian high school students. methods: this quasi‑experimental study was accomplished at four high schools that...

this study was designed to develop a modified tbi weight drop model for induction of focal mild cerebral injury. a stereotaxic coupled weight drop device was designed. principle arm of device carries up to 500g weights which their force was conveyed to animal skull through a thin nail like metal tip. to determine the optimal configuration of the device to induce mild tbi, six different trials w...

Many physical user interfaces are best viewed as an interacting collection of remotely-located distributed hardware and software components. The problem is that current physical user interface toolkits do not normally offer distributed systems capabilities, leaving developers with extra burdens such as device discovery and management, lowlevel hardware access, and networking. Our solution is Sh...

Background. In the study of wearable device users, it was found that the intentional motives for using wearable devices were a novelty, fun, and popular trends, but whether the needs and functions of device users will change due to the change the time is the focus of this study. Objectives. This study aims to examine the path relationships among motivation of use, exercise commitment, and exer...

background: educational interventions to promote physical activity are one of the health priorities. a theoretical approach to promote and maintain physical activity is the transtheoretical model (ttm). this research was conducted to determine the effects of this model on students' physical activity habits in 2011. methods: this quasi-experimental study was conducted on 200 students in two grou...

background : lack of physical activity is the fourth common cause of human death. given the increased rate of sedentary life style among employees, the aim of this study was to evaluate physical activity status of governmental employees in changing stage based on the transtheoretical model (ttm) in hamadan, iran, in 2014. methods: this descriptive-analytical study was performed on 1200 governme...

background: regular physical activity (pa) has positive effects on physical, psychological and social health in the individual and the community. reduced pa is a major global problem that is increasing in prevalence every day. the present study aimed to determine the status of pa among adolescent girls and their perceptions of obesity prevention. materials and methods: the present descriptive-a...

background: promoting physical activity is one of the most effective strategies for reducing the risk of some chronic and non-communicable diseases. one of the theoretical approaches to the promotion of physical activity is the transtheoretical model. the aim of this study was to determine the effect of transtheoretical model-based education on promoting physical activity among employees of abu...
