Gottlieb presents an early case study of his mobile augmented reality game Jewish Time Jump: New York design on the ARIS platform for the iPhone and iPad (iOS). The game is set on-location in Washington... READ MORE
With the growing popularity of mobile devices that have sophisticated localization capability, it becomes more convenient and tempting to give away location data in exchange for recognition and status in the social networks. Geosocial networks,... READ MORE
Analysis of eyetracking data can serve as an alternative method of evaluation when assessing the quality of computer-synthesized animations of American Sign Language (ASL), technology which can make information accessible to people who are deaf... READ MORE
My thoughts on the future of education in system administration. READ MORE
American Sign Language (ASL) is a visual gestural language which is used by many people who are deaf or hard-of-hearing. In this paper, we design a visual recognition system based on action recognition techniques to... READ MORE
Computer-based sign language recognition from video is a challenging problem because of the spatiotemporal complexities inherent in sign production and the variations within and across signers. However, linguistic information can help constrain sign recognition... READ MORE
We investigate a method for selecting recordings of human face and head movements from a sign language corpus to serve as a basis for generating animations of novel sentences of American Sign Language (ASL). Drawing... READ MORE
Animations of sign language can increase the accessibility of information for people who are deaf or hard of hearing (DHH), but prior work has demonstrated that accurate non-manual expressions (NMEs), consisting of face and head... READ MORE
Recent advancements in the accuracy of Automated Speech Recognition (ASR) technologies have made them a potential candidate for the task of captioning. However, the presence of errors in the output may present challenges in their... READ MORE
The percentage of the worldwide population with some form of disability is rising, and computing technologies, if accessible, could facilitate full participation in society for these users. However, the issue of equal access to technology... READ MORE
The main goal of this empirical research was to define those crucial leadership characteristics and behaviours of experienced individuals that confirmed them as leaders in the Croatian transition economy, based on success of their entrepreneurial... READ MORE
The goal of this covert channel is to prove the feasibility of using encrypted HTTPS traffic to carry a covert channel. The encryption key is not needed because the original HTTPS payload is not decrypted.... READ MORE
Recently, algorithms for object recognition and related tasks have become sufficiently proficient that new vision tasks can now be pursued. In this paper, we build a system capable of answering open-ended text-based questions about images,... READ MORE
A subliminal covert channel establishes a nearly undetectable communication session within a pre-established data stream between two separate entities. This document explains how HTTP can be utilized to facilitate a covert channel over both local... READ MORE
As the demand for skilled computer security professionals continues to increase, curricula at colleges and universities must continually evolve to meet current industry needs. Incorporating Metasploit module development into these curricula increases the value of... READ MORE
In this work we study the potential for utilizing the scattering of polarized neutrons from nuclei whose spin has been modulated using nuclear magnetic resonance (NMR). From first principles, we present an in-depth development of... READ MORE
This paper investigates the evolutionary foundation for our ability to attribute preferences to others, an ability that is central to conventional game theory. We argue here that learning others’ preferences allows individuals to efficiently modify... READ MORE
The Ramsey number R(C4, Km) is the smallest n such that any graph on n vertices contains a cycle of length four or an independent set of order m. With the help of computer algorithms... READ MORE
For graphs G1, G2, G3, the three-color Ramsey number R(G1, G2, G3) is the smallest integer n such that if we arbitrarily color the edges of the complete graph of order n with 3 colors,... READ MORE
We study a new problem for cubic graphs: bipartization of a cubic graph Q by deleting sufficiently large independent set I. It can be expressed as follows: Given a connected n-vertex tripartite cubic graph Q... READ MORE
Let ∆s = R(K3, Ks) − R(K3, Ks−1), where R(G, H) is the Ramsey number of graphs G and H defined as the smallest n such that any edge coloring of Kn with two colors... READ MORE
onic Liquids have emerged as effective lubricants and additives to lubricants, in the last decade. Halogen-free ionic liquids have recently been considered as more environmentally stable than their halogenated counterparts, which tend to form... READ MORE
