Choosing the best platform for distributed publish/subscribe communications usually implies a careful choice of the desired event selection model; content-based systems allow fine grained interest selection through expressive subscriptions usually at the cost of limited scalability; topic-based systems offer high-performance and scalable event dissemination at the cost of reduced expressiveness...
We have developed and evaluated three generalized systems for event detection. The first system is a simple brute force search method, where each space-time location in the video is evaluated by a binary decision rule on whether it contains the event or not. The second system is build on top of a head tracker to avoid costly brute force searching. The decision stage is a combination of state of...
This paper presents a general surveillance event detection system that participated in the interactive Surveillance Event Detection (iSED) task of TRECVID 2013. In the proposed system, a set of spatio-temporal features including Space-Time Interest Points (STIP) and Dense Trajectories are extracted, and a sliding temporal window is employed as the detection unit. Fisher Vector is used to encode...
Nowadays, organizational information systems are able to collect high volumes of data in event logs every day. Through process mining techniques, it is possible to extract information from such logs to support organizations in checking process conformance, detecting bottlenecks, and carrying on performance analysis. However, to analyze such “big data” through process mining, events coming from ...
We probe the dynamics of intermittent avalanches caused by steady addition of grains to a quasi-two-dimensional heap. To characterize the time-dependent average avalanche flow speed v(t) , we image the top free surface. To characterize the grain fluctuation speed deltav(t) , we use speckle-visibility spectroscopy. During an avalanche, we find that the fluctuation speed is approximately one-tent...
We report the first top-quark mass measurement that uses a cross-section constraint to improve the mass determination. This measurement is made with a dilepton tt event candidate sample collected with the Collider Detector II at Fermilab. From a data sample corresponding to an integrated luminosity of 1.2 fb(-1), we measure a top-quark mass of 170.7(-3.9)(+4.2)(stat)+/-2.6(syst)+/-2.4(theory) G...
In July 2007 the first contest of the Semantic Robot Vision Challenge (SRVC) was held at the annual conference for the Association for the Advancement of Artificial Intelligence (AAAI) in Vancouver, Canada. Four robot teams and two software-only teams entered the event. The performance of the top two robot competitors and the top software-only competitor showed that the technical goals of the c...
Many distributed systems use events for asynchronous communication. Although the CORBA Event Service provides a flexible model for event-based communication among objects, further work is needed to support the important features required by real-time applications such as network management, avionics, etc. where timely delivery of events and more complex event correlation are desirable. In this ...
The influence of event attributes on tourist’s loyalty: Evidence from the Ashoura event in Yazd City
Many studies have found that the perceived authenticity of cultural and religious events affects event satisfaction and loyalty. Little is currently known about how perceived authenticity is affected by the facilities, such as food and the availability of information, which are independent determinants of satisfaction and loyalty. This study aims to examine the antecedents of event loyalty. Que...
Experiences with the use of the MSC language for complex system specifications have shown that certain extensions are necessary in order to arrive at sufficiently transparent and manageable descriptions. Extended HMSCs, where MSC reference symbols may either be presented by hypertext-like descriptions or, in an expanded form, as detailed MSCs, appear to be especially suitable for a compact and ...
