background: this study was aimed to compare the diagnostic accuracy and feasibility of cone beam computed tomography (cbct) with phosphor storage plate (psp) in detection of simulated occlusal secondary caries. materials and methods: in this in vitro descriptive-comparative study, a total of 80 slots of class i cavities were prepared on 80 extracted human premolars. then, 40 teeth were randomly...

BACKGROUND Prechtl's method on the qualitative assessment of general movements (GMs) has been shown to be a good predictor of neurological outcome. There is substantial evidence that this method has good inter- and intra-observer agreement. AIMS We wanted to find out whether this high agreement is reproducible in the clinical setting. STUDY DESIGN Reliability study (inter- and intra-observe...

this paper addresses the design of an observer-based fault diagnosis scheme, which is applied to some of the sensors and actuators of a wind turbine benchmark model. the methodology is based on a modified sliding mode observer (smo) that allows accurate reconstruction of multiple sensor or actuator faults occurring simultaneously. the faults are reconstructed using the equivalent output error i...

OBJECTIVES There are no agreed criteria for osteoarthritis (OA) of the knee in population studies. The radiographic scoring system of Kellgren and Lawrence has been the system most used in the past and although other methods have been developed, comparisons have not been performed. Therefore these grading systems were compared in radiographs from a general population sample. METHODS Anteropos...

AIM The overall aim of this pilot study was to establish the role of dental practitioners in identifying patients at risk of osteoporosis from panoramic radiographs. METHODS The pilot study evaluated 32 randomly selected postmenopausal women with no known secondary cause of bone loss. A panoramic radiograph of each patient was taken and qualitative and quantitative radiomorphometric indices w...

The diagnostic contribution of 2-D shear-wave elastography (SWE) in management superficial lymph nodes (LNs) any origin was evaluated 222 patients referred for needle core biopsy. Each patient underwent conventional B-mode/Doppler ultrasound examinations (conventional ultrasound) and SWE. Quantitative SWE parameters qualitative map features were extracted. Carcinomas found to be significantly s...

this paper addresses a nonlinear observer based control scheme to synchronize chaotic systems subject to uncertainties and external disturbances. it is assumed that the dynamic of slave system is not completely known. in order to compensate for the system perturbation resulting from parameter variations and mismodeling phenomena, an adaptive neural network observer is employed to handle this pr...
