People with cognitive impairments have problems organizing their daily life autonomously. A virtual agent as daily calendar assistant could provide valuable support, but this requires that these special user groups accept such a system and can interact with it successfully. In this paper we present studies to elucidate these questions for elderly users as well as cognitively impaired users. Res...

We study the solar-cycle variations of solar p-mode travel time for different wave packets to probe the magnetic fields at the base of the solar convection zone. We select the wave packets which return to the same spatial point after traveling around the Sun with integral number of bounces. The change in onebounce travel time at solar maximum relative to minimum is approximately the same for al...

in this research, temporal and spatial behavior of siberian high (sh) was studied at the level of 1000 h.pa. this study has been done using daily data of geo potential height at 12 gmt in ncep/ncar database with spatial resolution of 2.5ã—2.5 degree in a 55 years period including 20089 days from january, 1st, 1951(dey, 11th, 1329) to december, 31st,2005(dey, 10th,1384). at first, the mean geo p...

Main results and achievements of 2002-2003 in neutrino physics are summarized. The field moves quickly to new phase with clear experimental and phe-nomenological programs, and probably, with new theoretical puzzle which may lead us to discoveries of the fundamental importance. One of the main results is amazing pattern of the lepton mixing which emerges from the data. The key questions are: Doe...

Numerology is a divine science that helps in knowing about the future of person. The assessment numerology based on date birth which turn calendars. Astronomy plays vital role many early civilizations, and one its most important applications timekeeping. Over centuries human history, calendars have been used worldwide to order time systematically. An essential part timekeeping calendars, as the...
