Emerging technologies are leading to the development of several new opportunities to guide and enhance learning that were unimaginable a few years ago. The move towards adopting mobile learning technologies is fast growing in both academic and industrial sectors. Mobile learning uses portable devices linked to a commercial public network, including different types of mobile phones and handheld computers. For mobile users, as well in all mobile applications, SMS messaging is found to be the most useful and convenient way of communication technology. In case of mobile learning, there are only limited forms for conducting tests using true/false method, multiple choice selection method etc. Answering short questions is a better way of testing the students to get more details about a particular entity. The practice of messaging can be thought of highly useful for answering such short-answer questions. The case where answers are to be given as short messages to the assessors, evaluating them may not be that much easier when compared to other simple types of tests. This paper focuses on using SMS for answering 'short words-answers' types of questions and evaluating them using simple matching process, providing enough feedback

Segmentation of pulmonary X-ray computed tomography (CT)

In view ofthe problems associated with under-machine inspection, there is a need to develop remote diagnostics systems capable of exploring narrow areas, capturing data and images from various modalities, and displaying the results at a remote location thus providing ease of identifying and diagnosing various machine problems. In this paper, we present a diagnostics system that is remotely controlled and can be deployed with a variety of imaging sensors to capture data. The software allows for segmenting the images and to mosaic the data for a thorough inspection.
