Telecom service providers are faced with an overwhelming flow of alarms, which makes good alarm classification and prioritisation very important. This paper first provides statistical analysis of data collected from a real-world alarm flow and then presents a quantitative characterisation of the alarm situation. Using data from the trouble ticketing system as a reference, we examine the relatio...

An Intruder is a hacker or cracker which always tries to get access to secure, system Intrusion occurs when an unauthorized person try to gain access or interrupt the normal operations of an information system. Even when such attacks ar e self-propagating, as in the case o f worms, Trojan Horses and denial-of service attacks, they are almost always initiated by an individual whose purpose is to...

objective: Through establishment a set of image recognition system based on mathematic models, to develop a auto alarm solution for the video monitoring system. Methods: compare the images the video monitoring system collected according to the time sequences. Then after binaryzation and wave filtering, the images were converted into numerical values using autocorrelation function, and the alarm...

Background: Monitoring serves to maintain physiologic variables within normal limits and when a parameter crosses a set threshold, an alarm is triggered. Therefore, this study aimed to determine whether alarm limits are properly adjusted in the neonatal intensive care unit (NICU) by nursing staff or not.Methods: The data concerning alarm limits corresponding to the three shifts of nursing...

An efficient flood alarm system may significantly improve public safety and mitigate damages caused by inundation. Flood forecasting is undoubtedly a challenging field of operational hydrology and a huge literature has been developed over the years. In this paper, we first define ordered ideal intuitionistic fuzzy sets and establish some results on them. Then, we define similarity measures betw...

BACKGROUND Clinical alarm systems safety is a national concern, specifically in intensive care units (ICUs) where alarm rates are known to be the highest. Interventional projects that examined the effect of changing default alarm settings on overall alarm rate and on clinicians' attitudes and practices toward clinical alarms and alarm fatigue are scarce. OBJECTIVE To examine if (1) a change i...

In this paper we describe the final version of a knowledge discovery system, Telecommunication Network Alarm Sequence Analyzer (TASA), for telecommunication networks alarm data analysis. The system is based on the discovery of recurrent, temporal patterns of alarms in databases; these patterns, episode rules, can be used in the construction of real-time alarm correlation systems. Also associati...

The aim of this work is to design an alarm system that allows protecting and preventing crop-freezing damages taking decisions with enough time to react. A first step was to obtain a temperature forecast mode. In this line an hourly temperature series was analyzed with Box-Jenkins methodology ( ARIMA models). An alarm system is designed based on these forecast, at each 12 hours, in the air temp...

This paper proposes a new method to learn time based rules from telecom system alarm data for prediction of the classes of alarms. A time based rule associates an alarm class with the StartTime attribute and other attributes of alarms. The rules are evaluated with the coverage of the rules in the training data set. Given a new alarm generated at a particular time, its alarm class can be predict...

The aim of this study was to get insight into the development of tactile interface for automobile warning system. In other words, it was investigated whether the important driving information in the right and left peripheral visual fields can be recognized faster using tactile warning system as compared with auditory warning system. The participants were required to simultaneously carry out a t...
