Text classification categorizes web documents in large collections into predefined classes based on their contents. Unfortunately, the classification process can be time-consuming and users are still required to spend considerable amount of time scanning through the classified web documents to identify the ones with contents that satisfy their information needs. In solving this problem, we firs...

In the present study, basil (Ocimum basilicum L.) and lovage (Levisticum officinale Koch.) extracts were obtained using maceration, ultrasound- microwave-assisted extractions (UAE MAE, respectively). Varying different extraction solvents, including water, methanol, acetone, ethyl acetate, analyses of total polyphenol flavonoid contents (TPC TFC, respectively), as well antioxidant properties (DP...

Currently there are few observations of the urban wind field at heights other than rooftop level. Remote sensing instruments such as Doppler lidars provide wind speed data at many heights, which would be useful in determining wind loadings of tall buildings, and predicting local air quality. Studies comparing remote sensing with traditional anemometers carried out in flat, homogeneous terrain o...

The Solar and Heliospheric Observatory (SOHO) was launched in December 1995 with a suite of instruments designed to answer long-standing questions about the Sun’s internal structure, its extensive outer atmosphere, and the solar wind. This paper reviews the new understanding of the physical processes responsible for the solar wind that have come from the past 8 years of SOHO observations, analy...
