Monitoring the environment for visual events while performing a concurrent task requires adjustment of visual processing priorities. By use of Bundesen's (1990) Theory of Visual Attention, we investigated how monitoring for an object-based brief event affected distinct components of visual attention in a concurrent task. The perceptual salience of the event was varied. Monitoring reduced the pr...
At the Belle II experiment a Time-of-Propagation (TOP) counter is used for particle identification in barrel region. This novel type of device combines Cherenkov ring imaging technique with time-of-flight and therefore it relies on precise knowledge time collision each triggered event. We discuss performance present maximum likelihood based method determination event from measured data.
Our work aims to build a bridge between constructive (top-down) and analytical (bottom-up) approaches to software verification. This paper presents a tool-supported method for linking two existing verification methods: Event-B (constructive) and Dafny (analytical). This method combines Event-B abstraction and refinement with the code-level verification features of Dafny. The link transforms Eve...
We update our search for the pair-produced super-symmetric partner of the top quark (stop quark) from 1.9fb−1 to 2.7fb−1 of data collected with CDF II. We search for the scalar top quarks via their decay channel: t̃1 → b + χ̃1 → b+χ̃1+ν+` which gives an event signature similar to that of a top dilepton event. We reconstruct events under the stop decay hypothesis and use the reconstructed stop mass...
This study investigated trends in performance and sex difference in swimming speed of elite open-water swimmers at FINA 10 km competitions (i.e. World Cup races, European Championships, World Championships and Olympic Games). Swimming speed and sex difference in swimming speed of the fastest and the top ten women and men per event competing at 10 km open-water races between 2008 and 2012 were a...
The field of high energy physics aims to discover the underlying structure of matter by searching for and studying exotic particles, such as the top quark and Higgs boson, produced in collisions at modern accelerators. Since such accelerators are extraordinarily expensive, extracting maximal information from the resulting data is essential. However, most accelerator events do not produce partic...
We present a direct measurement of the mass difference between t and t quarks using tt candidate events in the lepton+jets channel, collected with the CDF II detector at Fermilab's 1.96 TeV Tevatron pp Collider. We make an event by event estimate of the mass difference to construct templates for top quark pair signal events and background events. The resulting mass difference distribution of da...
حالت صورت اشخاص نقش مهمی را در روابط اجتماعی بازی می کند. بازشناسی حالت چهره به صورت اتوماتیک، یک فرآیند بسیار پیچیده و دشوار است زیرا این فرآیند، بسیار تحت تاثیر تغییرات روشنایی محیط و نوع چهره است. علاوه براین شباهت بین حالات مختلف باعث تشخیص اشتباه حالات چهره می شود. برای مثال چون در هر دو حالات خوشحالی و تعجب، دهان شخص باز است، امکان دارد این دو حالات به اشتباه به جای یکدیگر تشخیص داده شوند...
Chronic obstructive pulmonary disease (COPD) is one of the top five major causes of morbidity and mortality worldwide. Despite worldwide health care efforts, costs, and medical research, COPD figures demonstrate a continuously increasing tendency in mortality. This is contrary to other top causes of death, such as neoplasm, accidents, and cardiovascular disease. A major factor affecting COPD-re...
