The current study was carried out because of difficulties language advisers were experiencing with utilising the marking sheets to draw students’ attention to their strengths and weaknesses. A selection of 66 marking sheets with detailed comments from a variety of experienced raters was analysed and coded by two independent researchers. Themes were established regarding features that make a comment valuable or not valuable. Some of those same comments were then shared with students to determine whether or not they agreed with the advisers’ assessment.

Protein is composed of amino acids which are, in turn, made up of mostly carbon, hydrogen, oxygen, nitrogen. A protein structure consists of thousands of coordinates of its atoms. Building structure index tables (often organized by suffix trees or arrays) of proteins is an important phase for quickly searching or classifying protein structures.

Phishing is a real threat on the Internet nowadays. Therefore, fighting against phishing attacks is of great importance. In this paper, we propose a solution to this problem by applying Genetic Programming with features selection methods to phishing detection problem. We conducted the experiments on a data set including both phishing and legitimate sites collected from the Internet. We compared the performance of Genetic Programming with a number of other machine learning techniques and the results showed that Genetic Programming produced the best solutions to phishing detection problem.

We propose a content based video retrieval system in some main steps resulting in a good performance. From a main video, we process extracting keyframes and principal objects using Segmentation of Aggregating Superpixels (SAS) algorithm. After that, Speeded Up Robust Features (SURF) are selected from those principal objects. Then, the model “Bag-of-words” in accompanied by SVM classification are applied to obtain the retrieval result. Our system is evaluated on over 300 videos in diversity from music, history, movie, sports, and natural scene to TV program show.
