According to the SOHO/MDI observations (Duvall et al. 1998, Antia & Basu 1999) the solar f-mode frequency departs from the parabolic dispersion relation ω2 = gk. We propose to explain this behaviour in terms of a spaceand timedependent random flow that occurs in the convection zone. A time-dependent random flow speeds up the f-mode while the effect of a space-dependent random flow is to slow it...
A product customization system with integrated application services is helpful for small to medium-sized enterprises (SMEs). The mode of application service provider (ASP) particularly targets SMEs by providing integrated applications. The current product customization system seldom considers integrating with ASPs and orienting product lifecycle. In this article, an ASP-based product customizat...
We argue that the solar g-modes are unlikely to have caused the discrete peaks in the power spectrum of the solar wind flux observed by Thomson et al (1995). The lower limit to the energy of individual g-modes, using the amplitudes given by Thomson et al., is estimated to be at least 10 ergs for low-order g-modes; the resulting surface velocity amplitude is at least 50 cm s, larger than the obs...
The Lyman series of hydrogen was observed by SUMER on SOHO on the north polar limb of the Sun with a total exposure time of more than ten hours. The resulting line profiles have been analysed using the technique described by Marsch et al. (1999). The data analysis corroborates earlier findings on the Lyman lines, but also yields phenomena which cannot be fully understood at the present time. Fi...

The content of coronal material in the quiet Sun is not constant as soft X-ray and high-temperature EUV line observations have shown. New material, probably heated and evaporated from the chromosphere is occasionally injected even in the faintest parts above the magnetic network cell interiors. Assuming that the smaller events follow the pattern of the well observed larger ones, we estimate the...
New panel data from India are used to examine the relationship between farm size and productivity based on a model incorporating agency costs favoring family workers, scaledependent returns to mechanization arising from the fact that a larger contiguous land area is better-suited for high-capacity machinery, and falling credit costs with owned land. The model provides guidance for imputing the ...
This paper describes distortion calibration procedures for the SOHO/LASCO-C2 Coronagraph, based on in-orbit data and extensive image processing methods. It addresses specific problems of externally occulted coronagraphs (obstructed center of field-of-view, strong vignetting, and presence of stray light) and limitations inherent to space-based instrumentation (cosmic rays and limited number of r...
Enterprise Resource Planning (ERP) system in companies can be implemented to Multi National Corporation (MNC), Larger Enterprise, and Small & Medium-sized Enterprises (SMEs). In China, 99% of all companies can be categorized as SMEs. With a decade of high-speed economy development after entering the 21st century, traditional Chinese SMEs want to find a new management model to improve work effic...
The identification of flares in solar datasets implies using a thresholding process which excludes the majority of low-emission regions. In this paper we investigate a different measure of solar emission: the distribution of the total solar irradiance when integrated over the disk, obtained using extreme ultraviolet/soft X-ray observations from the SOHO CELIAS/SEM instrument. We show that durin...
