An Approach To Display Layout Of Dynamic Windows, Nihar Trivedi Jan 1997

An Approach To Display Layout Of Dynamic Windows, Nihar Trivedi

Theses: Doctorates and Masters

The development of windows based user interface has introduced a new dimension to the field of human computer interaction. Now a user is able to perform multiple tasks at a time, often switching from one task to another. However windows environment also imposes the burden of manual windows management on the user. Several studies have suggested that manual window management is an unproductive chore often resulting in clutter and confusion on the display screen. Therefore we need a automatic windows layout generator to free the user to perform other useful tasks. This thesis introduces SPORDAC {Shadow Propagation for Overlap Removal …


Randomised Shuffle And Applied Misinformation: An Enhanced Model For Contact-Based Smart-Card Serial Data Transfer, Michael Collins Jan 1997

Randomised Shuffle And Applied Misinformation: An Enhanced Model For Contact-Based Smart-Card Serial Data Transfer, Michael Collins

Theses: Doctorates and Masters

Contact-based smart-cards, which comply to the International Standard IS0-7816, communicate with their associated read/write machines via a single bi-directional serial link. This link is easy to monitor with inexpensive equipment and resources, enabling captured data to be removed for later examination. In many contact-based smart-cards the logical abilities are provided by eight-bit microcontroller units (MCU) which are slow at performing effective cryptographic functions. Consequently, for expediency, much data may be transferred in plain-text across the vulnerable communications link, further easing an eavesdropper's task. Practitioners in military communications protect transmitted information by varying a link's carrier frequency in an apparently random …
