In the above letter, Chin and Chen proposed an IEEE 1588 clock synchronization method based on dual slave clocks, where they claim that multiple unknown parameters — i.e., clock offset, clock skew, and master-to-slave delay — can be estimated with only one-way time transfers using more equations than usual. This comment investigates Chin and Chen’s dual clock scheme with detailed models for a m...

For decades Armenian studies has been marginalized in Middle Eastern, Turkish, Iranian, and Ottoman for political ideological reasons. 1 Ignorance reluctance to understand the field also have contributed this marginalization. Some scholars viewed as an archaic one, remote from above-mentioned fields. Whereas some only thought of part Caucasian studies, others did not want be associated with due...

Grapheme-color synesthetes experience color, not physically present, when viewing symbols. Synesthetes cannot remember learning these associations. Must synesthetic percepts be formed during a sensitive period? Can they form later and be consistent? What determines their nature? We tested grapheme-color synesthete, MC2, before, during and after she studied Hindi abroad. We investigated whether ...

The designation "Iranian Armenian community" already encompasses important social and anthropological presumptions and stances. The important impact of Armenians in spreading of innovation in socio-cultural and economic sphere as a religious, ethnic, cultural, and linguistic minority in Iran is discussed by examining the characterization, multiple identity, history, and economic activities. In ...

A hedonic price index and a quality-adjusted quantity index are constructed in order to provide a clearer picture of how slave quality evolved. Controlling for slave quality, slave prices did not rise as much as previously thought. This is due to an increase in slave quality, especially during the earlier 1800s. Properly accounting for the effect of the 1808 prohibition of slave importation, th...

there are two significant goals in teleoperation systems: stability and performance. this paper introduces an lmi-based robust control method for bilateral transparent teleoperation systems in presence of model mismatch. the uncertainties in time delay in communication channel, task environment and model parameters of master-slave systems is called model mismatch. the time delay in communicatio...

Background Pediatric respiratory allergies are increasing problem in Armenia being underestimated according to official reports. “Allergic Sensitization and Diseases in Armenian Children” study has been conducted to assess the prevailing sensitizations to inhalant allergens of Armenia using the standardized panel and method of PEP study (Pan-European standard Skin prick test study) conducted by...
