We study the task of recognizing human actions in video whilst paying attention to the shot and thread editing structure. Most existing action recognition algorithms ignore this structure, but it is generally present in edited TV and film material. To this end, we make the following contributions: first, we introduce a new dataset of human actions to study the occurrence/reoccurrence of pattern...

Predictive models for the exponential growth rate (EGR) and germination, outgrowth, and lag times (GOL) of Bacillus stearothermophilus previously developed in our laboratory were expanded to include higher salt (1.5%) formulations. The expanded models were validated in 7 military meals-ready-to-eat incubated at temperatures from 45 °C to 60 °C, and tryptic soy broth incubated from 37.5 °C to 70...

Real world protocols often involve human choices that depend on incentives, including when they fail and require fail-safe or fail-deadly mechanisms. We look at three example systems (the EMV protocol, consensus in cryptocurrencies, and Tor) in this context, paying particular attention to the role that incentives play in fail-safe and faildeadly situations. We argue that incentives should expli...

We propose a new model of branching processes, suitable for describing the behavior of general Petri nets, without any finiteness or safeness assumption. In this framework, we define a new class of branching processes and unfoldings of a net N , which we call faithful. These coincide with the safe branching processes and unfoldings if N is safe, or weakly safe as in [Engelfriet 1991], but not i...

A piloted flight simulator study investigated pilot control behavior while self-separating from a proximate aircraft during an instrument landing system approach. This “paired approach” operational concept pairs two aircraft, with the trail aircraft of the pair remaining within a safe zone calculated to be free (for a specified period of time) from collision danger and wake turbulence interacti...

This paper describes a research program designed to use agent models to understand how primates incorporate new, learned behavior safely into their established, reliable behavior repertoires. We suggest that some of the findings in the primate learning literature that we currently find surprising may in fact reflect evolved solutions to the problem of safe learning in intelligent agents. We ske...

Cognition in technical systems, as the ability to autonomously generate decisions, enables the systems to cope with heavily changing situations. But as its future behavior is not known a-priori, cognition adds new attributes to safety issues. The paper presents the application of an architecture for cognitive safety control to a manufacturing scenario. The architecture consists of an operationa...

Earthquake, an unpredictable natural disaster, poses a significant threat to public health, causing physical, human, social, cultural, and economic damages [1]. Iran is among the world's top 10 earthquake-prone countries—remembering earthquakes cause the greatest human casualties. Preparedness and safe behavior before and during earthquakes are crucially important to reduce the damage of earthq...

OBJECTIVE To evaluate the effectiveness of a skills training program in improving safe cycling behavior, knowledge, and attitudes in young children. METHODS Grade 4 children from six elementary schools in East York (a borough of Metropolitan Toronto) participated. The intervention--playground based instruction on bicycle handling skills by certified instructors--was randomly allocated to thre...
