A multimedia approach to the efficient implementation and use of emergency plans
2004
Because of the complexity of emergency procedures, the stressful situations during which they're executed, the emergency plan must be meticulously designed so that safety managers can quickly find needed information. Regardless of the complex procedures it describes and the trying situations where it would be used, the plan's success is always measured by how effective the evacuation is. Thus, safety-conscious organizations continually try to improve their emergency procedures and the way they present them in the emergency plan. Integrating incoming information during an emergency and correlating this information with the plan's procedures is a manual task for many safety managers. The dang…
An examination of the relationships among United States college students' media use habits, need for cognition, and grade point average
2013
The current study uses survey methods to understand how US college students' use of various types of social media, such as social networking websites and text messaging on smart phones, as well as consumption of traditional media, such as watching television and reading books for pleasure, is (or is not) related to intellectual cognitive processing and performance in school. The current results, which were based on a number of multiple regression analyses, revealed college students’ use of traditional media appears to be a significant and viable predictor of both college students’ grade point averages (GPAs) and their levels of need for cognition (NFC). On the other hand, college students’ …
An Interactive MIDI Accompanist
1998
The ability to infer beat and meter from music is one of the basic activities of musical cognition. After hearing only a short fraction of music, we are able to develop a sense of beat and to tap our foot along with the music. Even if the music is rhythmically complex, containing a range of different time values and possibly syncopation as well, we are capable of inferring the different periodicities present in the music and synchronizing to them. Simulating this activity with a computer program might seem, at first glance, to be simple. If a note onset (that is, an attack) occurs before the system expects it to occur, the estimated tempo is increased, and vice versa. In practice, however, …
BVS: A Lightweight Forward and Backward Secure Scheme for PMU Communications in Smart Grid
2011
In smart grid, phaser measurement units (PMUs) can upload readings to utility centers via supervisory control and data acquisition (SCADA) or energy management system (EMS) to enable intelligent controlling and scheduling. It is critical to maintain the secrecy of readings so as to protect customers' privacy, together with integrity and source authentication for the reliability and stability of power scheduling. In particular, appealing security scheme needs to perform well in PMUs that usually have computational resource constraints, thus designed security protocols have to remain lightweight in terms of computation and storage. In this paper, we propose a family of schemes to solve this p…

Putting documents into their work context in document analysis
2000
In trying to achieve document standardization the goal is to find more effective, consistent, and standardized ways to utilize information technology. The specification and implementation of document standards may take several years requiring a profound analysis and understanding of document management practices. Document standardization does not concern documents only: it concerns workers, their work, business partners, and future systems as well. In this paper we discuss two ways of describing the work context of documents: process modelling and life cycle modelling. In process modelling, documents are regarded as resources produced and used in inter- or intra-organizational business proc…
Discovering web services in social web service repositories using deep variational autoencoders
2020
Abstract Web Service registries have progressively evolved to social networks-like software repositories. Users cooperate to produce an ever-growing, rich source of Web APIs upon which new value-added Web applications can be built. Such users often interact in order to follow, comment on, consume and compose services published by other users. In this context, Web Service discovery is a core functionality of modern registries as needed Web Services must be discovered before being consumed or composed. Many efforts to provide effective keyword-based service discovery mechanisms are based on Information Retrieval techniques as services are described using structured or unstructured textdocumen…
Designing for Mixed Reality Urban Exploration
2021
Funding Information: Acknowledgments. This work was supported by the European Union Seventh Framework Programme (grant agreement no 601139) and the Italian Ministry of Education, University, and Research (MIUR) PON AIM project (id: AIM1875400-1, CUP: B74I18000210006). Publisher Copyright: © 2021. All Rights Reserved. This paper introduces a design framework for mixed reality urban exploration (MRUE), based on a concrete implementation in a historical city. The framework integrates different modalities, such as virtual reality (VR), augmented reality (AR), and haptics-audio interfaces, as well as advanced features such as personalized recommendations, social exploration, and itinerary manage…
MAC design on real 802.11 devices: From exponential to Moderated Backoff
2016
In this paper we describe how a novel backoff mechanism called Moderated Backoff (MB), recently proposed as a standard extension for 802.11 networks, has been prototyped and experimentally validated on a commercial 802.11 card before being ratified. Indeed, for performance reasons, the time critical operations of MAC protocols, such as the backoff mechanism, are implemented into the card hardware/firmware and cannot be arbitrarily changed by third parties or by manufacturers only for experimental reasons. Our validation has been possible thanks to the availability of the so called Wireless MAC Processor (WMP), a prototype of a novel wireless card architecture in which MAC protocols can be p…
Physical Metaphor for Streaming Media Retargeting
2014
We here introduce an image/video retargeting method that operates arbitrary aspect ratios resizing achieved in real-time performances. Most of the literature retargeting approaches sacrifice real-time performances in behalf of quality. On the other hand, existing fast methods provide arguable results. We can obtain a valuable trade-off between effectiveness and efficiency. The method named Spring Simulation Retargeting (SSR) is mainly based on a physical springs-based simulation. The media are assumed as flexible objects composed of particles and springs with different local stiffness properties, related to the visual importance of the content. The variation of the object size generates ela…
