Existence of outflow intrusion introduces small-scale turbulence that perturbs the vertically stratified character of the sound velocity and causes spatial and temporal fluctuations of the sound propagation. In this experimental study, we have investigated acoustic wave propagation with frequency of 50 kHz in a pre-stratified environment with intrusion of a turbulent plume while the si...

The present study aims to compare the unwanted intrusions experienced by obsessive-compulsive (OCD) and eating disorder (ED) patients, their appraisals, and their control strategies and analyse which variables predict the intrusions' disruption and emotional disturbance in each group. Seventy-nine OCD and 177 ED patients completed two equivalent self-reports designed to assess OCD-related and E...

Interruptions by others, or intrusions, are a common phenomenon in today’s workplaces. Intrusions can be disruptive for employees because they displace time required to complete job tasks (thereby increasing perceptions of workload). However, from a resources perspective, intrusions are associated with strain incrementally beyond that of displaced time through the depletion of self-regulatory a...

For testing Intrusion Detection Systems (IDS), it is essential that we be able to simulate intrusions in diierent forms (both sequential and parallelized) in order to comprehensively test and evaluate the detection capability of an IDS. This paper presents an algorithm for automatically transforming a sequential intrusive script into a set of parallel intrusive scripts (formed by a group of par...

While laptops and other Internet accessible technologies facilitate student learning in the classroom, they also increase opportunities for interruptions from off-task social networking sites such as Facebook (FB). A small number of correlational studies have suggested that FB has a detrimental effect on learning performance, however; these studies had neglected to investigate student-engagemen...

We present the results of an experimental study on the formation and propagation of thermohaline intrusions from an initial state that is stably stratified in two diffusing components. The intrusions form in a layer that contains compensating horizontal gradients of the two components and that lies above a denser reservoir layer that is homogeneous. In the initial state, a vertical barrier sepa...

Numerous post-ophiolite intrusions exposed into the late Cretaceous–Paleocene Sabzevar ophiolite belt, northeast Iran. The intrusions consist of calc-alkaline intermediate to felsic rocks with metaluminous to peraluminous in nature and adakitic affinities. Based on U-Th-Pb dating on separated zircons by SHRIMP Ⅱ, the emplacement age of these rocks into the ophiolite zone is constrained to ~45 M...

This paper describes the general requirements for an Intrusion Prevention and Detection System and the methods used to prevent and detect intrusions into Oak Ridge National Laboratory's network. In this paper we describe actual intrusions, how they were detected, and how they were handled. We also describe the monitoring tools we use for detecting intrusions.
