Noninvasive measurement of mechanical properties of biological tissues in vivo could play a significant role in improving the current understanding of tissue biomechanics. In this study, we propose a method for measuring elastic properties non-invasively by using internal indentation as generated by harmonic motion imaging (HMI). In HMI, an oscillating acoustic radiation force is produced by a ...

The objective of this study is to show that Harmonic Motion Imaging (HMI) can be used as a reliable tumor-mapping technique based on the tumor's distinct stiffness at the early onset of disease. HMI is a radiation-force-based imaging method that generates a localized vibration deep inside the tissue to estimate the relative tissue stiffness based on the resulting displacement amplitude. In this...

An intelligent human-machine interface (HMI) has been developed to enhance the safety and availability of a nuclear power plant (NPP) by improving operational reliability. The key elements of the proposed HMI are the large display panels that present synopsis of the plant status and the compact, digital workstations for monitoring, control, and protection functions. The workstation consists of ...

به علت تغییرات حجم ناشی از خطای ساخت، فرکانس کاواک‌های شتاب‌دهی در شتاب‌دهنده‌های خطی الکترون تغییر می‌کند. نتیجه تنظیم فرکانسی کاواک‌ها یکی مراحل مهم تست سرد است که باید الزامات آن طراحی لحاظ شود. پروژه ساخت ساختار موج‌ایستا برای شتاب­دهنده با دو انرژی، پس طراحی، یک آلومینیمی (شامل نیم کاواک و تزویج) ساخته شد. این جبران پیچ‌های استفاده پیچ‌ها جزیی کاواک‌ها، آن‌ها را می‌دهند. مقاله محاسبات شبیه...

In order to meet a high reliability requirement of subsea drilling, a redundant software system for subsea Blowout Preventers (BOP), including control logics, HMI programs, remote access and redundant databases are developed. The Bayesian networks for control logics, HMI programs and redundant databases are built and then the whole Bayesian networks are established. The quantitative reliability...

This paper proposes an adaptive Kalman filter (AKF) to improve the performance of a vision-based human machine interface (HMI) applied to a video game. The HMI identifies head gestures and decodes them into corresponding commands. Face detection and feature tracking algorithms are used to detect optical flow produced by head gestures. Such approaches often fail due to changes in head posture, o...

Objectives This study aimed at investigating the cellular mechanism of isoproterenol (ISO) on delayed afterdepolarizations (DADs) and triggered activity (TA) of the noninfarcted myocardium in the myocardial infarcted rabbit model.Methods Rabbits with the left anterior descending coronary artery occlusion were prepared and recovered for 8 wk (healed myocardial infarction, HMI). Myocytes were iso...

The work described in this paper was motivated by our experience with applying a framework for formal analysis of human-machine interactions (HMI) to a realistic model of an autopilot. The framework is built around a formally defined conformance relation called “fullcontrol” between an actual system and the mental model according to which the system is operated. Systems are well-designed if the...

We developed a hyperspectral microscopic imaging (HMI) platform that can precisely identify and quantify 10 molecular markers in individual cancer cells in a single pass. The exploitation of an improved separation of circulating tumor cells and the application of HMI provided an opportunity (1) to identify molecular changes in these cells, (2) to recognize the coexpression of these markers, (3)...
