This paper presents a tutorial for network anomaly detection, focusing on non-signature-based approaches. Network traffic anomalies are unusual and significant changes in the traffic of a network. Networks play an important role in today’s social and economic infrastructures. The security of the network becomes crucial, and network traffic anomaly detection constitutes an important part of netw...

Attempts to relate the quality of diet to growth in British children are plagued by two persistent anomalies. In the first, workers have found no consistent relationship between individual intake and growth. The biggest eaters are not necessarily the biggest individuals. As Widdowson said in 1947, ‘the present study has been unable to bring to light the laws which relate the height, weight, siz...

Understanding of human dynamics has drawn attention to various areas. Due to the wide spread of positioning technologies that use GPS or public Wi-Fi, location information can be obtained with high spatial-temporal resolution as well as at low cost. By collecting set of individual location information in real time, monitoring of human dynamics is recently considered possible and is expected to ...

Intrusion detection corresponds to a suite of techniques that are used identify attacks against computers and network infrastructures. As the cost information processing Internet accessibility falls, more organizations becoming vulnerable wide variety cyber threats. Web mining based intrusion generally fall into one two categories; misuse anomaly detection. In detection, each instance in data s...

In this longitudinal prospective observational study performed at a tertiary perinatal referral centre, we aimed to assess maternal distress in pregnancy in women with ultrasound findings of fetal anomaly and compare this with distress in pregnant women with normal ultrasound findings. Pregnant women with a structural fetal anomaly (n = 48) and normal ultrasound (n = 105) were included. We admi...

A social behavioral profile accurately reflects a user’s OSN activity patterns. People access OSNs using both traditional desktop PCs and new emerging mobile devices. With more than one billion users worldwide, OSNs are a new venue of innovation with many challenging research problems. In this paper, we study the social behaviors of OSN users, i.e., their usage of OSN services, and the applicat...

A model is presented in which the Pioneer anomaly is not related to the motion of the spaceship, but is a consequence of the acceleration of the cosmological proper time τ with respect to the coordinate parametric time t, i. e. of the value of d2τ/dt2 (> 0). Assuming flat spatial sections and that all the matter and energy is uniformly distributed throughout the universe, it is shown that this ...
