Lost sunspot cycle in the beginning of Dalton minimum: New evidence and consequences
[1] We have recently suggested that one solar cycle was lost in the beginning of the Dalton minimum during 1790s [Usoskin et al., 2001]. Earlier, this cycle has been combined with the preceding activity to form the exceptionally long solar cycle 4 in 1784-1799 with an irregular phase evolution. Here we show that historical data of auroral occurrence provide independent evidence for the existenc...
متن کاملGps-derived Local Tec Mapping over Peninsula Malaysia during Solar Minimum of Sunspot Cycle 24
The ionosphere is the major contributor of errors in Global Positioning System (GPS), especially during the 11-year sunspot cycle. The incoming 11-year sunspot cycle is expected to peak in 2013. The ionosphere condition is distinctly severe during ionospheric disturbances caused by high solar activity, which raises the question of how will this affect the ionosphere in the equatorial region, es...
متن کاملThe shape of the sunspot cycle described by sunspot areas
The temporal behavior of the sunspot cycles 12–22, as described by quarterly mean values of sunspot areas, can be represented by a single function containing only two parameters: the starting time and the amplitude of a cycle. The parameters are determined for the more recent 11 sunspot cycles and examined for any predictable behavior. As a sunspot cycle progresses, the amplitude parameter can ...
متن کاملThe sunspot cycle no. 24 in relation to long term solar activity variation
The solar minimum between solar cycles 23 and 24 during the period 2007-2009 has been the longest and deepest one at least since for the last 100 years. We suggest that the Sun is going to his next supercenturial minimum. The main aim of this paper is to tell about arguments concerning this statement. They are based on series of studies, which have been provided during the period since 1997 up ...
متن کاملthe analysis of the role of the speech acts theory in translating and dubbing hollywood films
از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
