background a number of developing countries have contracted out public health facilities to the non-government organizations (ngos) in order to improve service utilization. however, there is a paucity of in-depth qualitative information on barriers to access services as a result of contracting from service users’ perspective. the objective of this study was to explore perceived barriers to util...

Haptic interfaces are becoming more commonplace in virtual environment and teleoperation systems. There is a growing need to not only continue to improve hardware platforms and rendering algorithms, but evaluate human performance with haptic interfaces. This review summarizes two recent studies inspired by perception problems in using haptic interfaces to interact with virtual environments. The...

background: treatment and illness management depends mostly on patient's performance in diseases and disorders such as diabetes. therefore, self-care has an important role in the health of these patients; they can affect their own welfare, functional capabilities, and illness processes by achieving self-care skills. today, self-care depends on individual, psychological and social factors, recog...

Background:  Little is known about trends and predictors of hardware related infection following open reduction and internal fixation (ORIF) of extremity fractures, one of the major causes of failure following ORIF. The present study was designed and conducted to determine trends and predictors of infection-related hardware removal following ORIF of extremities using a nationally representative...

In this paper, a method is described that improves the perceived “smoothness” of motion depicted on rasterised Virtual Reality displays, by utilising the powerful information already contained in the virtual-world engine. Practical implementation of this method requires a slight realignment of one’s view of the nature of a rasterised display, together with modest modifications to current image ...

services require high involvement of consumer in consumption process. when consumers experience a service, their evaluation of service quality will change. the propose of current study is to provide a conceptual model for measuring hardware and software quality of banking services in the context of iran’s banking industry. current study is descriptive-applicable one in which has been done by a ...

many of the video processing algorithms cannot be implemented in real time on general computers, due to their computational complexity. for an efficient implementation, a custom hardware that can be reconfigured for the algorithm, is used. in this paper a new acceleration hardware based on fpga elements is proposed. this hardware can be adapted with the processing algorithm through fpga design ...

Background: There is an information gap in literature regarding postoperative outcome of total knee arthroplasty (TKA)in patients with hardware in-situ from the previous knee surgery. The present study aims to evaluate impact of retainedhardware on short-term outcome of TKA patients.Methods: Perioperative radiographs of patients who had undergone TKA between 2007 and 2012 were reviewedand patie...
