Abstract: In the recent years, evaluating the effectiveness of Web-based Information System (WBIS) is increasingly needed as it highly contributes to organizations, particularly on the employee task performance. This study is one of the fewest in Palestine in the field of WBIS assessment in which the effectiveness of WBIS is conceptualized and assessed in terms of employee task performance. It aims at investigating the effects of quality factors: service quality and information quality on the employee task performance. The data of the pilot study is collected from 39 of WBIS users in UNRWA. In the context of statistical inferential and analytical tests, correlation and regression analysis are used to analyze the data. The findings indicate that there are strong correlations between service quality, information quality and employee performance. Also, the findings indicate there are significant relationships between study factors. Therefore, it is expected that this study would contribute to empir

Abstract: This paper presents a study of automatic detection and recognition of bird species based on bioacoustics. The energy distribution in different frequency bands varies quite significantly among different birds’ sounds. Energy in various frequency bands is extracted using wavelet packet transform and k-nearest neighbor algorithm is used for classification. In our experiment, classification accuracy of 91% is achieved for the classification of eight bird species. A total of 307 bird sound files are used to train/test the system.
