Ossama, O., H. M. O. Mokhtar, and M. E. El-Sharkawi, "Clustering Moving Objects Using Segments Slopes", International Journal of Database Management Systems, vol. 3, issue 1, 2011. AbstractCu_pdf.pdf

Given a set of moving object trajectories, we show how to cluster them using k-means
clustering approach. Our proposed clustering algorithm is competitive with the k-means clustering
because it specifies the value of “k” based on the segment’s slope of the moving object trajectories. The
advantage of this approach is that it overcomes the known drawbacks of the k-means algorithm, namely,
the dependence on the number of clusters (k), and the dependence on the initial choice of the clusters’
centroids, and it uses segment’s slope as a heuristic to determine the different number of clusters for the
k-means algorithm. In addition, we use the standard quality measure (silhouette coefficient) in order to
measure the efficiency of our proposed approach. Finally, we present experimental results on both real
and synthetic data that show the performance and accuracy of our proposed technique.

Objectives: Colorectal polyps are important causes of rectal bleeding but they have been infrequently reported in Egyptian children. The prevalence and characteristics of colorectal polyps in a consecutive cohort of Egyptian children with rectal bleeding are presented. Methods: A total of 174 children aged 2-12 years [mean (SD) 6.4 (3.7)] with fresh rectal bleeding were enrolled prospectively. Rectal examination, laboratory investigations and fibre-optic colonoscopy were performed in all patients. Results: The source of bleeding was diagnosed as colorectal polyps in 100 patients (57.4%) and was owing to other causes in 74. The interval between onset of symptoms and presentation ranged from 2 to 48 months [mean (SD) 18.3 (16)]. In patients with other causes, rectal bleeding was attributed to intestinal amoebiasis (42), diarrhoea/dysentery (18), severe constipation (2) and intestinal schistosomiasis (2). Polyps were solitary in 56 children (56%) and ranged from 2 to 5 in 34 (34%) and >5 in 10 (10%). Polyps were confined to the rectum in 68 children, were rectosigmoid in 20, in the descending colon in 8, and splenic flexure in 4. Polyps were juvenile in 84 children (84%), inflammatory in 10 (10%) and hyperplastic, schistosomal or adenomatous in 2 each (6%). Colonoscopic polypectomy was successful and arrested the bleeding in all cases. Conclusion: In Egyptian children, colorectal polyps are relatively common and an easily treatable cause of fresh rectal bleeding. They should be high on the list of differential diagnoses.
