accuracy evaluation and adjustment of the first order leveling network of iran
in many countries, leveling networks are established for height determination which is one of the most important topics in geodesy. in these networks, the sum of the leveled height differences between a and b will not be equal to the difference in the orthometric heights ha and hb. the reason is that the leveling increment ?n, as we henceforth denote it, is different from the corresponding incr...
متن کاملRisk Leveling of Network Traffic Anomalies
The goal of intrusion detection is to identify attempted or ongoing attacks on a computer system or network. Many attacks aim to compromise computer networks in an online manner. Traffic anomalies have been an important indication of such attacks. Challenges in the detections lie in modeling of the large continuous streams of data and performing anomaly detection in an online manner. This paper...
متن کاملLuminosity leveling with angle
The very high luminosity foreseen for the LHC luminosity upgrade entails in all cases a significant luminosity decrease during a few hours run. We present in this note a new method of luminosity leveling, based on the on-line adjustment of the crossing angle, while keeping the optics unchanged. It is implemented using the D0 dipole of a possible Early Separation Scheme and an orbit corrector. T...
متن کاملLeveling the Grid
Motivated by an application in image processing, we introduce the grid-leveling problem. It turns out to be the dual of a minimum cost flow problem for an apex graph with a grid graph as its basis. We present an O(n) algorithm for this problem. The optimum solution recovers missing DC coefficients from image and video coding by Discrete Cosine Transform used in popular standards like JPEG and M...
