Introduction As tobacco advertising restrictions have increased, the retail 'power wall' behind the counter is increasingly invaluable for marketing tobacco products. Objective The primary objectives of this pilot study were 3-fold: (1) evaluate the attention paid/fixations on the area behind the cash register where tobacco advertising is concentrated and tobacco products are displayed in a r...

Introduction: Designing multimedia learning environments should consist of the evidence-based study and principals about the human learning process. Eye tracking is a way based on the learner processing of learning materials which presented in multimedia learning environments. The aim of the study was to examine the use of the eye-tracking method to investigate the cognitive processes in m...

The dynamics of the carotid artery wall has been recognized as a valuable indicator to evaluate the status of atherosclerotic disease in the preclinical stage. However, it is still a challenge to accurately measure this dynamics from ultrasound images. This paper aims at developing an elasticity-based state-space approach for accurately measuring the two-dimensional motion of the carotid artery...

BACKGROUND Automated function imaging (AFI) is a recently developed method of calculating the longitudinal peak systolic strains (LS) of the regional left ventricular (LV) wall using speckle tracking echocardiography and displaying them on a single bull's-eye map. The feasibility of AFI in patients with regional LV wall motion abnormalities caused by myocardial infarction (MI) was evaluated by ...

We study the effect of droplet coalescence on turbulent wall-bounded flows by means direct numerical simulations. In particular, volume-of-fluid and front-tracking methods are used to simulate channel containing coalescing non-coalescing droplets, respectively. find that droplets have a negligible drag, whereas ones steadily increase drag as volume fraction dispersed phase increases: indeed, at...

Tracking of moving people has gained a matter of great importance due to rapid technological advancements in the field of computer vision. The objective of this study is to design a motion based detection and tracking multiple walking pedestrians randomly in different directions. In our proposed method, Gaussian mixture model (GMM) is used to determine moving persons in image sequences. It reac...
