AIM To investigate the validity and reproducibility of touch imprint cytology (TIC) of core needle biopsies (CNBs) in the assessment of conspicuous breast findings. MATERIALS AND METHODS One hundred and fifty-eight conspicuous breast findings were assessed by CNB during a two-year period in this prospective study. TIC of the CNBs was used for cytological analysis. The performance of this tech...

INTRODUCTION Noninvasive fractional flow reserve (FFR) computed from CT (FFRCT) is a novel method for determining the physiologic significance of coronary artery disease (CAD). Several clinical trials have been conducted, but its diagnostic performance varied among different trials. AIM To determine the cut-off value of FFRCT and its correlation with the gold standard used to diagnose CAD in ...

The paper presents an algorithm which combining a neural network observer, it give more flexible and accurate control on the engine operation. In recent year, several researchers already proposed the algorithm which is based on a model-based adaptive control and uses artificial neural networks, and they assumed engine system is also controled by severe non-linear dynamics and their modelling. E...

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 Mathematical models of the immune response to the Human Immunodeficiency Virus demonstrate the potential for dynamic schedules of Highly Active Anti-Retroviral Therapy to enhance Cytotoxic Lymphocyte-mediated control of HIV infection. METHODS In previous work we have developed a model predictive control (MPC) based method for determining optimal treatment interruption schedules for...

A stable walking motion requires effective gait balancing and robust posture correction algorithms. However, to develop and implement such intelligent motion algorithms remains a challenging task for researchers. Effective sensory feedback for stable posture control is essential for bipedal locomotion. In order to minimize the modelling errors and disturbances, this paper presents an effective ...

objective: diagnosis of vertical root fractures (vrfs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. despite cone beam computed tomography (cbct) has significantly enhanced image quality compared to digital radiography (dr) which aid the diagnosis, artifacts has remained as a problem in vrf detection . th...

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...

In this paper, we propose a suboptimal moving horizon estimator for general class of nonlinear systems. For the stability analysis, transfer "feasibility-implies-stability/robustness" paradigm from model predictive control to context estimation in following sense: Using suitably defined, feasible candidate solution based on an auxiliary observer, robust proposed is inherited independently lengt...

The heating section of an annealing furnace is a plant that raises the temperature steel strips to desired target ensure achieve material properties. Model predictive control (MPC) has been used increase in previously published studies, because it reflects geometrical and characteristics strip. An accurate model for required optimization MPC. For large complex furnace, nonlinear models from exi...
