Experimental studies with HCI by CORONA group at TMU

Experimental Studies on Corona Discharge Ionization

This study investigates the possibility of corona discharge ionization technique for reduction of fog. For corona discharge ionization a high voltage power supply is designed and developed indigenously. The high output voltage is developed by using isolation transformer, autotransformer, and high voltage neon transformer and it is converted into DC voltage by using Wheatstone bridge circuit and...

Challenges of Replicating Empirical Studies with Children in HCI

In this paper, we discuss the challenges of conducting a direct replication of a series of mobile device usability studies that were originally conducted with adults and older children (ages 7 to 17). The original studies were designed to investigate differences in how adults and children use mobile devices to touch targets and create surface gestures. In this paper, we report on a replication ...

Studies on Corona-charged Polypropylene Fibrous Electrets

The corona-charged fibrous electrets are dielectric materials exhibiting quasi-permanent electrical charge imparted by means of corona discharge process. The electrical charge in the electret fibrous materials has been utilized to capture hazardous particles from complex air streams. Air filters of this kind are widely used as respirators and face masks in personal protective equipments, dust c...

Postgraduate Studies in the Field of HCI

Experimental Studies of Diffractive Processes at Hera

Diffractive processes in photon-proton interactions at HERA offer the opportunity to improve the understanding of the transition between the soft, non-perturbative regime in hadronic interactions at Q2 = 0 and the perturbative region at high Q2. Recent experimental results from HERA on inclusive diffractive scattering, exclusive vector meson production and the properties of the hadronic final s...
