Taxonomic Rules for Password Policies: Translating the Informal to the Formal Language

Taxonomic Rules for Password Policies: Translating the Informal to the Formal Language

A password policy may seem formal in the sense that it is written in a legalistic language, giving the impression of a binding contract. However, such policies are informal in the logical sense that the policy statements are not written in a clear

Depicting Web Images for the Blind and Visually Impaired

A prototype to translate web graph and map images into 3D printed models in order to give the blind and visually impaired access to voting and election information.

4-Way Handshaking Protection for Wireless Mesh Network Security in Smart Grid

4-Way Handshaking Protection for Wireless Mesh Network Security in Smart Grid

Wireless mesh/sensor networks offer various unique features such as self-configuration, ease of installation, scalability, and self-healing, which makes them very attractive for deployment in various smart grid domains, such as Home Area Networks (HAN)

Sparse Embedding-based Domain Adaptation for Object Recognition

Sparse Embedding-based Domain Adaptation for Object Recognition

Domain adaptation algorithms aim at handling the shift between source and target domains. A classifier is trained on images from the source domain; and the classifier recognizes objects in images from the target domain. In this paper, we present a joint

Providing Disruption QoS in an OFDM System Using Residual Idle Time Based Opportunistic Spectrum Access

Providing Disruption QoS in an OFDM System Using Residual Idle Time Based Opportunistic Spectrum Access

Dynamic spectrum access (DSA) is emerging as a promising technology to mitigate spectrum scarcity caused by static frequency allocation. Among the different models proposed for DSA, opportunistic spectrum access (OSA) is a promising class of solutions. In

Exploring Local Features and the Bag-of-Visual-Words Approach for BioImage Classification

Exploring Local Features and the Bag-of-Visual-Words Approach for BioImage Classification

With recent advances in imaging technologies large numbers of bioimages are currently being acquired. Automated classification of these bio-images is a very important and challenging problem. Here we investigate the capabilities of local features and the

Delay Behavior of On-Off Scheduling: Extending Idle Periods

Delay Behavior of On-Off Scheduling: Extending Idle Periods

On-off scheduling of systems that have the ability to sleep can be used to extend system idle periods and enable greater opportunities for energy savings from sleeping. In this paper, we achieve a theoretical understanding of the delay behavior of on-off

Combining Genetic Algorithms & Simulation to Search for Failure Scenarios in System Models

Combining Genetic Algorithms & Simulation to Search for Failure Scenarios in System Models

Large infrastructures, such as clouds, can exhibit substantial outages, sometimes due to failure scenarios that were not considered during system design. We define a method that uses a genetic algorithm (GA) to search system simulations for parameter
