Image Processing – I: Research Design For Evaluation Of Finger Input Properties On Multi-Touch Screen, Ahsan Ullah, Ahmad Kamil B. Mahmood, Suziah Sulaiman, Muzafar Khan

International Conference on Information and Communication Technologies

Interactive tabletop display provides a collaborative workspace to users around a table. Users sit in front of each other and they perform direct and collaborative multi-touch interaction simultaneously. Users access the interactive elements using their bare fingers. The finger works as a pointer device, and it has direct relation with the size, shape, and configuration of the interactive elements on sensitive displays. It is found that there is lack of precise selection of small size interactive elements owing to users' fat fingers. In this regard, it is aimed to propose a research design to evaluate the finger input properties in …

Network Security: Privacy-Preserving Data Publication: A Review On “Updates” In Continuous Data Publication, Adeel Anjum, Guillaume Raschia Jul 2011

Network Security: Privacy-Preserving Data Publication: A Review On “Updates” In Continuous Data Publication, Adeel Anjum, Guillaume Raschia

International Conference on Information and Communication Technologies

Preserving the privacy of individuals while publishing their relevant data has been an important problem. Most of previous works in privacy preserving data publication focus on one time, static release of datasets. In multiple publications however, where data is published multiple times, these techniques are unable to ensure privacy of the concerned individuals as just joining either of the releases could result in identity disclosure. In this work, we tried to investigate the major findings in the scenario of continuous data publication, in which the data is not only published multiple times but also modified with INSERTS, UPDATES and DELETE …

Networks - Ii: Modified On Demand Transmission Power Control For Wireless Sensor Networks, Mirza M Yasir Masood, Ghufran Ahmed, Noor M. Khan Jul 2011

Networks - Ii: Modified On Demand Transmission Power Control For Wireless Sensor Networks, Mirza M Yasir Masood, Ghufran Ahmed, Noor M. Khan

International Conference on Information and Communication Technologies

On Demand Transmission Power Control (ODTPC) is a well known transmission power control strategy that is used to reduce high power consumption in wireless sensor networks (WSNs). In this paper, we propose an extension to ODTPC and thus, a modified version of ODTPC is proposed named MODTPC. Simulation results show that performance of MODTPC is better than ODTPC in terms of efficiency and energy saving.

Networks - I: A Dynamic Transmission Power Control Routing Protocol To Avoid Network Partitioning In Wireless Sensor Networks, Ghufran Ahmed, Noor M. Khan, Mirza M Yasir Masood

International Conference on Information and Communication Technologies

Power utilization in an efficient manner is a hot research issue in wireless sensor networks (WSNs). WSNs consist of energy hungry sensor nodes. Researchers have been trying to increase the lifetime of WSN since the development of WSN technology. Dynamic Transmission Power Control (DTPC) is a method for an efficient utilization of the energy resource and thus leads to an increase in lifetime. It has been used for the determination of minimum transmission power. A valuable study about the impact of variable transmission power on link quality has already been present in literature. In contrast to DTPC, transmitting data at …

International Conference on Information and Communication Technologies

This paper describes the design, implementation and comparison of two Mamdani Fuzzy Logic Controllers for wall tracking behavior of mobile robot. Both the controllers take inputs from two ultrasonic sensors and generate motion commands for left and right motors. The controllers are designed using MATLAB and implemented in real time using an inexpensive and readily available microcontroller, AT89C52. The controllers differ in membership functions and the rule base which provides a mean for their comparison. Experimental results have validated both the controllers; however they exhibit different settling time and percentage overshoot due to the difference in the membership functions and …

Artificial Intelligence - I: Adaptive Automated Teller Machines - Part Ii, Ghulam Mujtaba, Tariq Mahmood Jul 2011

Artificial Intelligence - I: Adaptive Automated Teller Machines - Part Ii, Ghulam Mujtaba, Tariq Mahmood

International Conference on Information and Communication Technologies

Nowadays, the banking sector is increasingly relying on Automated Teller Machines (ATMs) in order to provide services to its customers. Although thousands of ATMs exist across many banks and different locations, the GUI and content of a typical ATM interface remains, more or less, the same. For instance, any ATM provides typical options for withdrawal, electronic funds transfer, viewing of mini-statements etc. However, such a static interface might not be suitable for all ATM customers, e.g., some users might not prefer to view all the options when they access the ATM, or to view specific withdrawal amounts less than, say, …

Artificial Intelligence – I: Usability Studies In Haptic Systems, Muzafar Khan, Suziah Sulaiman, Abas M. Said, Muhammad Tahir

International Conference on Information and Communication Technologies

Haptic systems that deal with force and tactile feedback are widely used in different domains. Usability evaluation plays an important role to assess these systems and user's experience. Many usability evaluation studies for haptic systems have been reported but no effort is made to effectively summarize those works; thus, little is known on the extent in which the methods applied are useful for these systems. Literature survey is performed to find out the patterns related to different evaluation methods and haptic devices used in various domains. The survey findings indicate for a need of new usability methods that would be …

Artificial Intelligence – I: A Preliminary Framework For Human-Agent Communication In Electronic Negotiations, Moez Ur Rehman, Nosheen Riaz Jul 2011

Artificial Intelligence – I: A Preliminary Framework For Human-Agent Communication In Electronic Negotiations, Moez Ur Rehman, Nosheen Riaz

International Conference on Information and Communication Technologies

Electronic negotiations are business negotiations conducted via electronic means using information and communications technologies (ICT). Two dominant types of electronic negotiation systems are automated negotiation systems for software agents and negotiation support systems (NSSs) for humans. However, the integration of two types for human-agent negotiations is an important task. In this paper, an extended communication model for human-agent business negotiations is presented. For this purpose, the underlying communication models of automated negotiations and NSSs are analyzed. The extended communication model is based on a common negotiation ontology which captures the negotiation agenda and paves the way for such hybrid communication, …

On The Ethical Possibility Of Sustainability: A Challenge For Higher Education, Eric Bain-Selbo Jul 2011

On The Ethical Possibility Of Sustainability: A Challenge For Higher Education, Eric Bain-Selbo

Education for Sustainability Summer Institute

At the heart of the sustainability movement are two questions central to its viability: Are human beings capable of treating the Earth ethically? Are human beings capable of acting morally responsibly for the benefit of distant future generations? Answers to both questions are unclear. This paper draws upon the work of 20th century critical theorists to identify the ethical core of these questions. In the process, the paper will show what would be necessary for us to answer these questions affirmatively. The paper concludes with reflections about how higher education, and interdisciplinary inquiry in particular, can be critical to …
