IntelliEye: Enhancing MOOC Learners' Video Watching Experience with Real-Time Attention Tracking

Massive Open Online Courses (MOOCs) have become an attractive opportunity for people around the world to gain knowledge and skills. Despite the initial enthusiasm of the first wave of MOOCs and the subsequent research efforts, MOOCs today suffer from retention issues: many MOOC learners start but do not finish. A main culprit is the lack of...

The Effect of Shielding Gas Composition on Weld Bead Geometry during Short-circuit GMA Welding of Inconel625 Alloy

Recently, X65 carbon steel pipes internally clad with a thin Inconel625 alloy lining are highly used. However, during welding the Inconel625 lining in the root pass, the weld bead is uneven. To avoid weld defects in the successive passes, an additional grinding procedure is always required to flatten the weld bead. It is known that as an...

Automatic Detection and Diagnosis of faults in Sensors used in EMS

A much occurring problem in the Energy Management Systems of existing buildings and HVAC services is that the measurements are unreliable. In this article a methodology is described which can be used to determine the presence of errors in energy monitoring, caused by faulty measurements. These errors can be detected and subsequently diagnosed....

Measurement Study of Multi-point Videoconferencing

From the 80s, with the rapid development of the Internet, videoconferencing made significant progress and played an important role in economics, education and remote healthcare. A lot of applications and models appeared. More and more companies and people get used to communicate through a video conferencing service. Therefore, it is important to...

Measurement study of multi-party video conferencing

More and more free multi-party video conferencing applications are readily available over the Internet and both Server-to-Client (S/C) or Peer-to-Peer (P2P) technologies are used. Investigating their mechanisms, analyzing their system performance, and measuring their quality are important objectives for researchers, developers and end users. In...

Integral pavement/soil-wall structures: A numerical study

A short range, low data rate, 7.2 GHz-7.7 GHz FM-UWB receiver front-end

A 9 mW FM-UWB receiver front-end for low data rate (<50 kbps), short range (<10 m) applications operating in the ultra-wideband (UWB) band centered at 7.45 GHz is described in this paper. A single-ended-to-differential preamplifier with 30 dB voltage gain, a 1 GHz bandwidth FM demodulator, and a combined (preamp/demodulator) receiver front-end...
