Intrusion behavior has the characteristics of fast upgrade, strong concealment In this paper, an integrated network intrusion detection algorithm by combining. judge the safety of a system or network. (6). Intrusion Detection Systems (IDS) are primarily centered on characteristic probable incidents, observation data. ABSTRACT: Intrusion Detection Systems are designed to detect system attacks Re...

In this paper, a new method for mineral boundary detection is proposed using a model prepared in ArcGIS ModelBuilder tool. Required data for this method are gray scale images taken from petrographic thin sections. The images are captured in 19 numbers through 90° polarizers and lambda plate rotation with 5° intervals while the microscope table is fixed. Mineral boundaries are detected using the...

Hyperosmia is suspected in pregnancy; however, no empirical study using validated measures of olfactory function has clearly confirmed the anecdotal reports of this phenomenon. The goal of the current study is to compare the olfactory sensitivity of pregnant women to that of nonpregnant women and men. All participants rated their sense of smell and pregnant women listed the odors to which they ...

The literature suggests that nondeclarative, or nonconscious, learning might be impaired among HIV-seropositive (HIV+) individuals compared with HIV-seronegative (HIV-) matched control groups, but these studies have included relatively few women. We administered measures of motor skill and probabilistic learning, tasks with a nondeclarative or procedural learning component that are dependent on...

The statistical modeling of social network data needs much effort  because of the complex dependence structure of the tie variables. In order to formulate such dependences, the statistical exponential families of distributions can provide a flexible structure. In this regard, the statistical characteristics of the network is provided to be encapsulated within an Exponential Random Graph Model (...

"Peak shift" is a behavioral response bias arising from discrimination learning in which animals display a directional, but limited, preference for or avoidance of unusual stimuli. Its hypothesized evolutionary relevance has been primarily in the realm of aposematic coloration and limited sexual dimorphism. Here, we develop a novel functional approach to peak shift, based on signal detection th...

In this paper, we propose an adaptive statistical time-frequency method to detect broken bars using digital torque estimation. The key idea in the proposed method is to transform motor current into a time-frequency spectrum to capture the time variation of the frequency components and to analyze the spectrum statistically to distinguish fault conditions from the normal operating conditions of t...

With the widespread application of wind turbines, the Maintenance issue gets growing concern. Bearings play a critical role in industrial applications. It is necessary to effectively monitor their health status. The shock pulse method (SPM) can detect the incipient fault of bearings and prevent the fault consequence effectively. However, many researchers used laboratory data to validate the SPM...

BACKGROUND Increasing colorectal cancer screening (CRCS) is important for attaining the Healthy People 2020 goal of reducing CRC-related morbidity and mortality. Evaluating CRCS trends can help identify shifts in CRCS, and specific groups that might be targeted for CRCS. METHODS We utilized medical records to describe population-based adherence to average-risk CRCS guidelines from 1997 to 200...
