Improved modeling of photon observables with the event-by-event fission model freya

Applications of Event-by-Event Fission Modeling with FREYA

The recently developed code FREYA (Fission Reaction Event Yield Algorithm) generates large samples of complete fission events, consisting of two receding product nuclei as well as a number of neutrons and photons, all with complete kinematic information. Thus it is possible to calculate arbitrary correlation observables whose behavior may provide unique insight into the fission process. We firs...

Fission Reaction Event Yield Algorithm FREYA User Manual

From nuclear materials accountability to detection of special nuclear material, SNM, the need for better modeling of fission has grown over the past decades. Current radiation transport codes compute average quantities with great accuracy and performance, but performance and averaging come at the price of limited interaction-by-interaction modeling. For fission applications, these codes often l...

Modeling Documents with Event Model

Currently deep learning has made great breakthroughs in visual and speech processing, mainly because it draws lessons from the hierarchical mode that brain deals with images and speech. In the field of NLP, a topic model is one of the important ways for modeling documents. Topic models are built on a generative model that clearly does not match the way humans write. In this paper, we propose Ev...

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...
