In this paper comparative study of proposed hybrid multilevel inverter (HMI) operating in modified pulse width modulation (PWM) mode with cascaded H-bridge multilevel inverter (CHMI) is done. Two types of HMIs are proposed with same configuration. To control the two HMIs, modified PWM techniques are derived from sinusoidal pulse width modulation (SPWM) to reduce the switching losses in the inve...

In this paper, we consider the concept of the impact of an action or human-error. We begin from an informal definition of impact as: the effect that an action or sequence of actions has on the safe and successful operation of a system. and develop a quantitative measure of the impact of specified behaviours. It is important that human-machine interface (HMI) designers should understand the rela...

Humans’ are multimodal beings that perceive their environment with all their senses, which allows them to create situational awareness (van Laack, 2014). For driver vehicle interaction the idea of multimodality has been neglected in the past and displays became the most common information output in a cockpit. To handle the significant increase of traffic complexity and information availability ...

به منظور ساخت، راه‌اندازی و عیب‌یابی مقدماتی چشمه پنینگ داخلی سیکلوترون 10IRANCYC، یک مگنت الکتریکی دوقطبی با میدان مغناطیسی در حد امکان مشابه مرکز مذکور طراحی ساخته شد. این الکترومگنت که دانشکده فیزیک دانشگاه تهران شد، قادر است بزرگی 7000 گوس را محل استقرار (منطقه‌­ای شعاع 15 میلی‌متر مگنت) آسانی بدون نیاز خنک‌سازی تأمین کند. دست‌­یابی 1/1 تسلا نیز استفاده از برای مدت چند دقیقه امکان‌­پذیر است...

Working Group 1 on health and medical informatics education of the International Medical Informatics Association (IMIA) has established a WWW site (http:/(/)ix.urz.uni-heidelberg.de/-d16) to provide up-to-date information about its work. The core of the site is an underlying database providing information on health and medical informatics (HMI) programs and courses worldwide. To be able to have...

This paper discusses a new approach to the development of industrial manufacturing control systems. In industry, there is an increasing need for more intelligent and agile control systems which are able to be flexible in their operations. Through use of the new IEC 61499 standard, a new design methodology for modeling industrial control systems has been developed with these goals in mind. A des...

The development process of automotive human machine interfaces (HMIs) is traditionally characterized by a number of discontinuities. A diverse set of stake-holders participate in this development process, all of which have their own perspectives, use their own approaches, and rely on their own representational frameworks and tools. Our strategy to overcome the existing discontinuities relies on...

Accurate 3D hand pose estimation plays an important role in Human Machine Interaction (HMI). In the reality of HMI, joints in fingers stretching out, especially corresponding fingertips, are much more important than other joints. We propose a novel method to refine stretching-out finger joint locations after obtaining rough hand pose estimation. It first detects which fingers are stretching out...

This paper presents a human machine interface (HMI) for hands-free control of an electric powered wheelchair (EPW) based on head movements and facial expressions detected by using the gyroscope and ‘cognitiv suite’ of an Emotiv EPOC device, respectively. The proposed HMI provides two control modes: 1) control mode 1 uses four head movements to display in its graphical user interface the control...

SCADA protocols for Industrial Control Systems (ICS) are vulnerable to network attacks such as session hijacking. Hence, research focuses on network anomaly detection based on meta–data (message sizes, timing, command sequence), or on the state values of the physical process. In this work we present a class of semantic network-based attacks against SCADA systems that are undetectable by the abo...
