Mixing Mechanisms in Density Intrusions
In addition to gravity current front dynamics, another mixing behavior has been studied (sedimentary double diffusion, SDD). Laboratory experiments have been performed which explore conditions the only previous study did not. The experimental data obtained herein has been combined with the data …

Lattice matching for detecting distributed intrusions
… on intrusion detection has focused on sequential intrusions. However, intrusions can also be formed by concurrent interactions of multiple processes. Some of the intrusions caused by these events cannot be detected using sequential intrusion detection methods. Therefore, there is a need for a …

Investigating system intrusions with data provenance analytics
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-04-06 without embargo terms

Petrology of the Numabin Bay intrusions, Reindeer Lake, Saskatchewan
A magmatic origin of a differentiated Precambrian granitic pluton, consisting of quartz diorite, granodiorite, and quartz monzonite, is consistent with the results of petrographic and structural studies. Petrographic modal analyses and accurate plagioclase determinations by the Rittman Zone Method …

Origin of net-veined and mixed-magma ring intrusions
Net-veined and mixed-magma ring intrusions are a characteristic simultaneous emplacement of mafic, intermediate and silicic magmas. Net-veined ring-intrusions consist of areas of granophyric net-veined mafic to intermediate rock which elsewhere forms rounded to elongate pillows in a silicic host …

Reduced-order modeling of granular intrusions driven by continuum approaches
Granular intrusions such as ballistic impacts, vehicular and animal locomotion in natural terrains, and stirring of materials in industrial processes are common. Granular media often exhibits coupled solid-like and fluid-like multiphase characteristics in such systems that are commonly not shown by …

Detection and prevention of intrusions in power system cyber-physical infrastructure
Cyber-attacks on SCADA (supervisory control and data acquisition) systems used by industrial control systems (ICS), e.g., power grids, can cause severe damage. In December 2015, remote intruders penetrated a Ukrainian power grid and caused a blackout that affected 225,000 residents. Mitigating …

Petrology and geochemistry of syenite intrusions in the Eastern Province of Zambia
… nepholine-sodalite varieties.The ,Sinda syenite intrusions are oversaturated potassics which form a petrogenetically related N-S trending string of intrusions at the eastern margin of the Sinda batholith.The northernmost Lusandwa intrusion is a composite diapir covering some 70sq Km whilst the …

Embedded monitors for detecting and preventing intrusions in cryptographic and application protocols.
… our anomaly-based IDS designed for detecting intrusions in cryptographic and application-level protocols. Our system has several unique characteristics, such as the ability to monitor cryptographic protocols and application-level protocols embedded in encrypted sessions, a very lightweight …

Petrology of Metadiabase Intrusions in the White Rock Quadrangle, Western North Carolina
<p>The White Rock quadrangle is located in extreme west central North Carolina, at the northwest edge of the Blue Ridge thrust sheet. The geology of the north-central ninth of the quadrangle was mapped during this study. This map area primarily consists of Precambrian granitic gneisses of the Blue …

Quantifying The Properties Of Magmatic Intrusions In The Central Andes With Geodesy
… constrain the physical properties of two active intrusions in the CVZ that are unique in terms of their large size (>50km diameter) and persistent maximum rates of uplift (>1 cm/yr for >10yrs). First, I focus on Uturuncu Volcano, where I analyze InSAR and GPS data to constrain the spatial and …

Seismicity associated with magmatic intrusions: insights from the Reykjanes Peninsula, southwest Iceland
… governing the ongoing eruptions and the magmatic intrusions that precede them. Microseismicity is a powerful lens through which to view these processes, providing the means to track melt movement as it triggers earthquakes in the surrounding crust. This dissertation makes use of an exceptional …

Geochemistry and petrogenesis of the Tsirub nephelinite-basanite intrusions, Aus, southern Namibia
Nephelinite-basanite intrusions found on the Tsurib farm near Aus in southern Namibia are described for the first time. The petrography is very similar to each other wih texture ranging from porphyritic to microporphyritic where olivine is dominant, and sometimes the only, …

Modelling Viscous Flow and Elastic Deformation in Fold-Thrust Belts and Magmatic Intrusions
… belts and the dynamics of shallow magmatic intrusions. Although geophysically distinct, these two problems both involve the interplay between viscous flow and elastic deformation and so inform the modelling of one another. Fold-thrust belts are formed at convergent margins, where accretion …

Intrusions of sub-Antarctic surface water across the subtropical convergence southwest of Africa
… intrusion episodes. In order to investigate intrusions of SAASW into the Agulhas Retroflection region, all available data of any kind have been accessed and analyzed. A serial satellite study, using both METEOSAT and NOAA images, suggests that approximately four intrusions of SAASW are …
