conclusions since the difference between groups was significant in three domains of qol, it can be concluded that the training could influence the qol of mothers of children with cerebral palsy. training the parents by experts is recommended. results the mean differences in three domains of qol including the physical health, psychological health, and environmental health, were significant betwe...

The widely applied location-based services require a high standard for positioning technology. Currently, outdoor positioning has been a great success; however, indoor positioning technologies are in the early stages of development. Therefore, this paper provides an overview of indoor fingerprint positioning based on Wi-Fi. First, some indoor positioning technologies, especially the Wi-Fi finge...

Closed reduction and fixation with 3 cannulated screws is a widely accepted surgery for the treatment of femoral neck fractures. However, how to obtain optimal screw placement remains unclear. In the current study, the authors designed a guide pin positioning system for femoral neck fracture cannulated screw fixation and examined its application value by comparing it with freehand guide needle ...

background: after radiofrequency catheter ablation of arrhythmias, patients have to bed rest for 4-6 h to prevent bleeding and hematoma. however, such a rest may cause back pain in the patients. the aim of this study was to determine the effects of continuous change in body position during and after the radiofrequency ablation on the back pain. materials and methods: in a quasi‑experimental des...

Against the problem that indoor positioning suffers quite large errors and irregular user location movement, this paper adopts Support Vector Regression (SVR) for initial positioning and Kalman filtering for filtering of the positioning results so as to improve the accuracy of the positioning system. The experimental results show that against the real WLAN environment, SVR positioning results p...

Nowadays RFID indoor targets positioning results display methods are simplified. The positioning results visual effect is also unsatisfied. To solve this problem, we design and realize a comprehensive method to implement RFID indoor localization algorithms in a geographic information system. In our method, the RFID indoor targets positioning results can display in the real geographic environmen...

Location-based services are about to take the next step to proactive services which need continuous positioning for monitoring spatial objects. But so far that also results in severe battery drain in mobile devices due to deficient positioning APIs and the absence of energy-efficient positioning with several positioning methods. By using a hierarchical positioning concept this work provides a g...

Localization technologies have been an important focus in ubiquitous computing. This paper explores an underrepresented area, namely computer vision technology, for outdoor positioning. More specifically we explore two modes of positioning in a challenging real world scenario: single snapshot based positioning, improved by a novel highdimensional feature matching method, and continuous position...

Wi-Fi indoor positioning algorithms experience large positioning error and low stability when continuously positioning terminals that are on the move. This paper proposes a novel indoor continuous positioning algorithm that is on the move, fusing sensors and Wi-Fi on smartphones. The main innovative points include an improved Wi-Fi positioning algorithm and a novel positioning fusion algorithm ...

To exploit the complementary strengths of WiFi positioning, pedestrian dead reckoning (PDR), and landmarks, we propose a novel fusion approach based on an extended Kalman filter (EKF). For WiFi positioning, unlike previous fusion approaches setting measurement noise parameters empirically, we deploy a kernel density estimation-based model to adaptively measure the related measurement noise stat...
