Challenge Patient Dispatching in Mass Casualty Incidents
No full textEfficient management of mass casualty incidents is complex, since regular emergency medical services struc-tures have to be switched to a temporary “disaster mode” involving additional operational and tactical struc-tures. Most of the relevant decisions have to be taken on-site in a provisional and chaotic environment. Data gathering about affected persons is one side of the coin; the other side is on-site patient dispatching requiring information exchange with the regular emergency call center and destination hospitals. In this paper we extend a previous conference contribution about the research project e-Triage to the aspect of patient data and on-site patient dispatching. Our considerations reflect the situation in Germany, which deserves from our point of view substantial harmonization
GABEK WinRelan® – a Qualitative Method for Crisis Research Engaging Crisis Management Personnel
No full textQualitative research methods like GABEK WinRelan are advantageous tools to analyze and thereby improve crisis management planning and communication systems by interrogating crisis management personnel.
Contrary to quantitative methods they help to identify, explore, and structure new important aspects in this field and to formulate more specific research questions. This paper describes the usage and advantages of the qualitative method GABEK WinRelan within crisis management research, particularly within the e-Triage project which aims at the development of an electronic registration system of affected persons in mass casualty incidents. Furthermore it addresses different corresponding research fields like stress within emergency missions and the role GABEK WinRelan could play in examining these research fields
Providing Accessible and Portable Video Lecture from Content Transcoding
No full textE-learning has the potential to reach students worldwide, making education a resource available to every user, anywhere, anytime, and from any network and device. However, many people will be excluded from the benefits of Web-based education if constrains to guarantee so wide an access are not considered in the design stage. Offering universal access to E-learning and T-learning does not mean sacrificing interactivity or appeal by producing text-based lectures. Furthermore, as technologies develop, rich media are becoming common resources for e-learning activities and a set of transcoding mechanisms could effectively improve portability and accessibility of on-line lectures. In this context, we present an application designed to support accessibility of on-line education that automatically produces accessible and portable versions of lectures, to be experienced on different networks, applications and devices
Kate: The Keen Android Travel Extension
No full textKate is a working prototype that shows that an app can assist a traveller in the travel decision process. Kate is built up from modules, the source of travel data (now the calendar) and travel time prediction (now Tripcast from Model IT) can easily be switched to another source which will require only the change of one module.Man Machine InteractionMediamaticsElectrical Engineering, Mathematics and Computer Scienc
Securing Data by Steganography on Small Devices
No full textSteganography is a well known, and long standing, technique to hide data into data. The actual small devices, such as the smartphones, provide a complete set of capabilities to cipher and decipher text into pictures.
In this paper we propose an application that enables the user to exploit the capabilities of smartphones to hide and retrieve data into pictures taken by means of the onboard camera. The limited computational power and storage capacity of a small device are enough to allows their user to take advantage of a sophisticated technique such as the steganography.
By means of our application a smartphone becomes a self-contained device that enables the user to easily hide, store, and retrieve secure data. Moreover, those data can be securely sent and received by means of the Multimedia Messaging Service, MMS, a common technique to exchange images in the actual scenario of cellular telephony
Bayesian Classification of Disaster Events on the Basis of Icon Messages of Observers.
No full textDuring major disaster events, human operators in a crisis center will be overloaded with a flood of phone calls. As an increasing number of people in and around big cities do not master the native language, the need for automated systems that automatically process the context and content of information about disaster situations from the communicated messages becomes apparent. To support language-independent communication and to reduce the ambiguity and multitude semantics, we developed an icon-based reporting observation system. Contrast to previous approaches of such a system, we link icon messages to disaster events without using Natural Language Processing. We developed a dedicated set of icons related to the context and characteristic features of disaster events. The developed system is able to compute the probability of the appearance of possible disaster events using Bayesian reasoning. In this paper, we present the reporting system, the developed icons, the Bayesian model, and the results of a user test.Intelligent InteractionElectrical Engineering, Mathematics and Computer Scienc
Talking to the computer: At the Information Technology & Systems faculty of TU Delft, Ir. Robert van Vark has come up with a method for travel information queries that can chat flexibly
No full textWhenever computers communicate with humans, for example on the telephone, the machine will conduct the dialogue along strictly defined lines. After all,computers can't cope with the rather casual way humans tend to converse. So what you get is a form to be filled in on the screen, or at best a question and answer routine with a limited range of options. At the Information Technology & Systems faculty of tu delft, Ir. Robert van Vark has come up with a method for travel information queries that can chat flexibly
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
B.O.O.S. (Bestuurder: Oogjes Open Systeem)
No full textIn slaap vallen in het verkeer is nog steeds een grote oorzaak van verkeersongevallen en leidt elk jaar nog tot veel slachtoffers. Een systeem dat kan helpen om deze ongevallen te voorkomen zou derhalve erg nuttig zijn. Het doel van het project B.O.O.S. is om een systeem te ontwikkelen dat kan detecteren wanneer de bestuurder van een auto in slaap aan het vallen is en hem daarop te attenderen door middel van een geluidssignaal. Om te detecteren of iemand in slaap aan het vallen is wordt door het systeem continu gekeken naar de status van de ogen en wordt er aan de hand van de resultaten beredeneerd of er actie ondernomen moet worden. Dit project laat zien dat het goed mogelijk is om een systeem te maken dat kan detecteren wanneer iemand in slaap valt en actie kan ondernemen om zo (dodelijke) ongelukken in het verkeer te voorkomen.Electrical Engineering, Mathematics and Computer Scienc
Almost Blue: the Design of a Cooperative Game by Integrating Accessible Interaction
No full textCurrently on-line entertainment is an important quality of life issue and represents a cornerstone of human culture and communication. With the growingly significant diffusion of mobile and multimodal devices, on-line entertainment is increasingly considered in an anytime, anywhere, anyone dimension. In this context new forms of on-line entertainment are offered to users, combining networked gaming, story telling and high interactivity in mixed reality contexts. This paper presents design issues related to the development of an accessible game where users cooperate to catch a serial killer. The application has been designed taking into account accessibility and offers multimodal access to sustain users with disabilities in being completely involved in the game scenario. The game, that supports edutainment issues, is built on an agent based simulation system
