Activation of the left midfusiform gyrus in response to reading words and pseudowords is such a reliable finding in functional imaging that this region has been called "the visual word form area" (VWFA). However, this label has recently been challenged, because activation in VWFA is also observed in other lexical tasks. We evaluated whether VWFA is necessary, sufficient, or specialized for read...

In this position paper I discuss methods for analyzing, designing, and evaluation usable security systems. The discussion is rooted in a long-term engagement in the study and design of usable user authentication technologies in hospitals. Based on this empirical background, I discuss lessons learned and some of the challenges I see in this area. These discussions are intentionally open-ended in...

Recently, kernel-based tracking algorithms such as the mean shift tracking algorithm has been proposed. However, there exists an inherent instability problem which is due to the use of an isotropic kernel for spatiality. In this paper, In this paper, we propose a new tracking algorithm : the weighted mean of the centroids corresponding to each color bin of the target. The weight is determined b...

In the spring of 2006, I taught a graduate student research seminar on usable security at Brigham Young University (BYU). It was likely one of the first graduate seminars devoted exclusively to the nascent field of usable security. The course consisted primarily of readings from Security and Usability, a collection of papers in the field that had recently been edited by Cranor and Garfinkel [2]...

Abstract In 2014, a gravity-fed rural piped water supply system (GFRPWSS) was constructed in the northern part of Malawi at cost $6.8 million (MK5 billion). The designed to serve 35,007 people by 2020 but time study, ability users association (WUA) operate and maintain as well financial sustainability (i.e. if scheme could run without external support) were unclear. Financial records showed tha...

Phanera mekongensis , a new species from Phu Wua Wildlife Sanctuary, NortheasternThailand, is described and illustrated. The morphological description of the provided discussed in comparison with closely related species. molecular data nuclear chloroplast markers show that taxon robustly positioned well-supported clade includes type genus, P. coccinea .
