PURPOSE To compare radiation dose and image quality between a slot-scanning system (SSS) and a dynamic flat-panel detector (DFD) in assessing scoliosis in children. METHODS An experimental study was first performed with a phantom to assess the quality of each device. The clinical part included a prospective observational dosimetric and qualitative comparative study with acquisition of whole-s...

In this paper, a bi-objective mixed-integer linear optimization model for Closed-loop Supply Chain Network Design Problem (CLSCND) is developed. The proposed model includes both the forward and reverse directions and includes different types of facilities, namely, manufacturing/remanufacturing centers, warehouses, and disassembly centers. The first objective function tried to minimize the total...

Abstract Introduction: Dentofacial deformity (DFD) and the breathing mode can change head posture. However, posture changes after orthognathic surgery are controversial, no studies were found on relationship between in adults with DFD. Objective: To identify main young affected by DFD, to verify if modifies posture, is associated Methods: Twenty-five assessed divided dentofacial group (DFD; n =...

Abstract In this paper, we propose a novel global motion estimation technique based on weighted gradient and Displaced Frame Difference (DFD) associated with Wiener estimation. Then, we apply this technique to parse events of a high level of understanding in a cricket game. A user oriented analysis of the game then reveals a distinct connection between the global motion and specific events. By ...

PURPOSE To measure the distance between the optic disc center and the fovea (DFD) and to assess its associations. METHODS The population-based cross-sectional Beijing Eye Study 2011 included 3468 individuals aged 50+ years. The DFD was measured on fundus photographs. RESULTS Readable fundus photographs were available for 2836 (81.8%) individuals. Mean DFD was 4.76 ± 0.34 mm (median: 4.74 mm...

The accuracy of three-dimensional object reconstruction using depth from defocus (DfD) can be severely reduced by elliptical lens deformation. This paper presents two correction methods, correction by deformation cancellation (CDC) and correction by least squares fit (CLSF). CDC works by subtracting the current deformed depth value by a prestored deformed value, and CLSF by mapping the deformed...

Today, most of the Object-Oriented (OO) software development methodologies analyze requirements in terms of objects and their interactions. However, requirements are more naturally to be specified functionally. Our informal survey with the Chinese software engineers in this region also strongly reflects this. This paper proposes an enhanced data flow diagram (DFD) called data flow net (DF net) ...
