Do multi-view X-ray systems improve X-ray image interpretation in airport security screening?
Scientific Essay from the year 2008 in the subject Ergonomics, , language: English, abstract: Verbessern Multi-View Röntgensysteme die Interpretation von Röntgenbildern bei den Sicherheitskontrollen im Flughafen? In der Luftfahrtsicherheit ist das Röntgen von Gepäckstücken bei der Sicherheitskontrolle eines der Hauptelemente zur Prävention terroristischer Anschläge. Es wurden große Investitionen in neue Technologien getätigt, wie zum Beispiel in Multi-View Röntgensysteme. Dabei handelt es sich um Röntgengeräte, die aufgrund multipler Röntgenstrahlen mehrere Röntgenbilder von einem Gepäckstück erstellen, sodass die Mitarbeitenden der Sicherheitskontrolle von diesem Gepäckstü...
Neuroscience perspectives on Security: Technology, Detection, and Decision Making
In security science, efficient operation depends typically on the interaction between technology, human and machine detection and human and machine decision making. A perfect example of this interplay is ‘gatekeeping’, which is aimed to prevent the passage of people and objects that represent known threats from one end to the other end of an access point. Gatekeeping is most often achieved via visual inspections, mass screening, random sample probing and/or more targeted controls on attempted passages at points of entry. Points of entry may be physical (e.g. national borders) or virtual (e.g. connection log-ons). Who and what are defined as security threats and the resources available to...
HCI and Usability for Education and Work
The Workgroup Human–Computer Interaction & Usability Engineering (HCI&UE) of the Austrian Computer Society (OCG) serves as a platform for interdisciplinary - change, research and development. While human–computer interaction (HCI) tra- tionally brings together psychologists and computer scientists, usability engineering (UE) is a software engineering discipline and ensures the appropriate implementation of applications. Our 2008 topic was Human–Computer Interaction for Education and Work (HCI4EDU), culminating in the 4th annual Usability Symposium USAB 2008 held during November 20–21, 2008 in Graz, Austria (http://usab-symposium.tugraz.at). As with the field of Human–Computer Inter...
Biologically Motivated Computer Vision
This book constitutes the refereed proceedings of the Second International Workshop on Biologically Motivated Computer Vision, BMCV 2002, held in Tübingen, Germany, in November 2002. The 22 revised full papers and 37 revised short papers presented together with 6 invited papers were carefully reviewed and selected from 97 submissions. The papers are organized in topical sections on neurons and features, motion, mid-level vision, recognition - from scenes to neurons, attention, robotics, and cognitive vision.
Psychosocial Job Dimensions and Distress/Well-Being: Issues and Challenges in Occupational Health Psychology
Over the last three decades a large body of research has showed that psychosocial job dimensions such as time pressure, decision authority and social support, could have significant implications for psychological distress and well-being. Theoretical models, such as the job demand-control-social support model (JDCS model), the effort-reward imbalance model (ERI model), the job demands-resources model (JDR model) and the vitamin model suggest that distress and positive dimensions at work (well being and motivation) can be considered as two sides of the same coin. If the job is designed to provide the right mix of psychosocial job dimensions (e.g., optimal time pressure, decision authority and ...
Newton's Principia Revisited
PROBLEM. The treatise is devoted to the reconstruction of our 'instinctive beliefs' in classical mechanics and to present them 'as much isolated and as free from irrelevant additions as possible'. The same motivation has driven many authors since the publication of Newton's Principia. IMPORTANCE. Classical mechanics will remain the basic reference and tool for mechanics on terrestrial and planetary scale as well as the proto-theory of relativistic and quantum mechanics. But it can only serve its purpose if it is not considered as obsolete, but if its foundations and implications are understood and made 'absolutely' clear. METHOD. Based on the 'instinctive belief' that the foundations of clas...
User Interfaces for Wearable Computers
Hendrik Witt examines user interfaces for wearable computers and analyses the challenges imposed by the wearable computing paradigm through its dual-task character. He introduces a special software tool as well as the “HotWire” evaluation method to facilitate user interface development and evaluation. Based on the results of different end-user experiments conducted to study the management of interruptions with gesture and speech input in a wearable computing scenario, the author derives design guidelines and general constraints for forthcoming interface designs.
Aviation Security Management
Because of 9/11, there is universal recognition that aviation security is a deadly serious business. Still, around the world today, the practice of aviation security is rooted in a hodgepodge of governmental rules, industry traditions, and local idiosyncrasies. In fact, nearly seven years after the largest single attack involving the air transport industry, there remains no viable framework in place to lift aviation security practice out of the mishmash that currently exists. It is the ambitious intent of Aviation Security Management to change that. The goals of this set are nothing less than to make flying safer, to make transporting goods by air safer, and to lay the foundation for the pro...
