The experiments at Run 2 of the Tevatron have each accumulated over 1 fb −1 of high-transverse momentum data. Such a dataset allows for the first precision (i.e. comparisons between theory and experiment at the few percent level) tests of QCD at a hadron collider. While the Large Hadron Collider has been designed as a discovery machine, basic QCD analyses(More)
Nearly all present-day commercial intrusion detection systems are based on a hierarchical architecture. Nodes at the bottom of the hierarchy collect information, which is passed to higher nodes in the hierarchy until the root node is reached. The root node is a command and control system that evaluates attack signatures and issues responses. Many single(More)
 This paper describes the new method of time-interval-error (TIE) estimation and prediction. This method is very useful for standard clocks characterization and can be applied in high precision measurement and telecommunication systems with high resolution of the time-base. TIE can be easily and fast calculated using only two parameters obtained during(More)
We present a study of high-p T photon and pion production in hadronic interactions, focusing on a comparison of the yields with expectations from next-to-leading order perturbative QCD (NLO pQCD). We examine the impact of phenomeno-logical models of k T smearing (which approximate effects of additional soft-gluon emission) on absolute predictions for photon(More)
Selected recent QCD and top-quark results from the Tevatron are reviewed , aiming to illustrate progression from basic studies of QCD processes to verification of perturbative calculations and Monte Carlo simulation tools, and to their applications in more novel and complex cases, like top-quark studies and searches for new physics. QCD processes provide(More)
One of the methods used for presenting the results of the time-interval measurement is a two-sample-difference of quantized data histogram calculation method. The proposed Sub-Channel method allows to increase the precision and minimizes the influence of nonlinearity and quantization error during the time-interval histogram calculation. It is possible to(More)
– The authors present the methods of ECG signal simulation especially ST-Elevation Myocardial Infarction known as STEMI. It occurs in the case of blood flow around and towards heart problem. It is strongly associated with a heart attack due to low level of oxygen transported to the heart muscle. The most common symptoms of this disease are chest pain,(More)
In this paper compared the algorithms proposed in the method in wireless sensor network. Energy consumption is very important for self-powered radio nodes. But in some applications energy balancing is more important. Wireless sensor networks used in large areas like farmland or warehouses consist of hundreds of nodes. In classic method routing is directed(More)
