A study of high density bit transition requirements versus the effects on BCH error correcting codes
The use of PN sequence generators to create a minimum number of transitions in an NRZ bit stream is described. The CSG encoder/decoder design was constructed and demonstrated
Analysis of space telescope data collection system
An analysis of the expected performance for the Multiple Access (MA) system is provided. The analysis covers the expected bit error rate performance, the effects of synchronization loss, the problem of self-interference, and the problem of phase ambiguity. The problem of false acceptance of a command word due to data inversion is discussed. A mathematical determination of the probability of accepting an erroneous command word due to a data inversion is presented. The problem is examined for three cases: (1) a data inversion only, (2) a data inversion and a random error within the same command word, and a block (up to 256 48-bit words) containing both a data inversion and a random error
Event-specific and individual factors impacting college students’ decisions to intervene in a potentially risky scenario
Universities have attempted to address sexual violence on campuses through various prevention programs, including bystander intervention. Unfortunately, the extant literature on bystander intervention
has primarily focused on bystander characteristics. Little is known about how situational characteristics affect the likelihood of intervening during sexual violence; yet, these variables have the potential to influence the effectiveness of bystander intervention programs. Using data collected from college students (N¼626) at a single university located in a large Southern metropolitan city, the present study utilizes a factorial survey design to investigate the impact of location, victim/offender sex, and perceptions of alcohol use on self-reported probability of intervention in an ambiguous sexual scenario. Results indicate that participants were more likely to intervene in scenarios that depicted a fraternity-hosted social (vs. on-campus) and less likely when there was a female perpetrator and a male victim. Perceived alcohol use did not impact intervention.Journal Articl
Memoryscapes : Designing Situated Narratives of Place through Heritage Collections
Memoryscapes presents a detailed case-study of a design-led inquiry concerning the development of immersive experiences to support city-center urban redevelopment, to encourage visiting and touristic activity. Our approach sought to explore how we might make innovative use of local heritage assets, within these digital experiences, to enhance engagement with place. We brought historians, “placemakers”, design-creatives, and technology-developers into dialogue, in a series of co-design sessions (over 9 months, through 6 workshops and with 77 participants). Our initial workshop allowed us to explore and develop extant theories of trajectories and immersive experiences, which led to the development of a design toolkit. The toolkit facilitated further co-design sessions with stakeholder communities. This paper contributes a deepening and nuancing of theory of trajectories by applying it in a specific context, namely heritage-led immersive experiences for use in urban areas; and provides critical reflections on the design toolkit to support interdisciplinary stakeholder development of immersive urban experiences
