Interactivity in the classroom is reported to promote a more active learning environment, facilitate the building of learning communities, provide greater feedback for lecturers, and help student motivation. Various definitions of interactivity exist in the literature, alternately focusing on the participants, structure and technology. The PLS TXT UR Thoughts research project builds on existing...
systems (SM-DMS) are growing rapidly in wireless communication applications in various areas, such as electromagnetic field (EMF) management, wastewater monitoring, and air pollution supervision, etc. However, delay in short messages often makes the data embedded in SM-DMS transmit unreliably. Moreover, there are few regulations dealing with this problem in SMS transmission protocols. In this s...
This paper presents the approach we developed for automatic multi-document summarization applied to short message contextualization, in particular to tweet contextualization. The proposed method is based on named entity recognition, part-of-speech weighting and sentence quality measuring. In contrast to previous research, we introduced an algorithm from smoothing from the local context. Our app...
All blood bank services, especially those of developing countries, face a major shortfall of blood donations due to lack of voluntary blood donors. Our study aims to evaluate the acceptability of Short Message Service based interventions towards becoming voluntary blood donors among medical university students of Karachi, Pakistan. Methods. A total of 350 medical students were approached in med...
Short Message Service (SMS) is a popular form of nonverbal mobile communication. To date, most research has focused upon the use of SMS by teenagers and young adults. Our work examines the use of SMS by middleaged users. We conducted a usability study evaluating the ease of use or difficulties experienced by middle-aged individuals whilst engaging in text message objectives and SMS tasks, in ea...
Granboulan [4] proposed the signature scheme in the ideal cipher model named OPSSR that achieves the lower bound for message expansion. In this paper, we propose a scheme which can give the security equivalent to that of OPSSR in the random permutation model that is weaker than the ideal cipher model. We also show exact security proof. We extend our scheme to the multi key setting. By the resul...
The paper describes experiments using grid searches over various combinations of machine learning algorithms, features and preprocessing strategies in order to produce the optimal systems for sentiment classification of microblog messages. The approach is fairly domain independent, as demonstrated by the systems achieving quite competitive results when applied to short text message data, i.e., ...
A power-control method based on tracking of interference power by use of a Kalman filter, proposed earlier for packet-switched TDMA wireless networks, does not yield performance gain in case of short message length and/or moderate control delay. The major reason is that the interference prediction by the filter may not be accurate enough due to little interference temporal correlation. In this ...
