Critical Infrastructure Systems Modelling: Benchmarking Cpntools, Graeme Pye, Matthew J. Warren

Australian Information Warfare and Security Conference

This paper reports on the application of systems modelling benchmarks to determine the viability of systems modelling software and its suitability for modelling critical infrastructure systems. This research applies the earlier research that related to developing benchmarks that when applied to systems modelling software will indicate its likely suitability to modelling critical infrastructure systems. In this context, the systems modeling benchmarks will assess the practicality of CPNTools to the task of modelling critical infrastructure systems.

Managing Analysis, David Shaw

Australian Information Warfare and Security Conference

The Intelligence profession requires effective management to function properly and professional discourse highlights the changing nature of intelligence work. Highlighted “failures” are linked to organizational structures and ethos, and proposals to address the problems include discussion of human and organizational factors with recommendations that address the issues. However, optimising the intelligence process may not be a simple case of applying management techniques as the work relies substantially on individual endeavour. Innovative management techniques are needed and these should be grounded in recognising the peculiar nature of analysis and the skill set required.

Effects Of Water Vapor On The Kinetics Of The Methylperoxy Radical Self-Reaction And Reaction With Hydroperoxy, Alecia Mower

Theses and Dissertations

The gas phase reactions of CH3O2 + CH3O2, HO2 + HO2, and CH3O2 + HO2 in the presence of water vapor have been studied at temperatures between 263 and 303 K using laser flash photolysis coupled with UV time-resolved absorption detection at 220 nm and 260 nm. Water vapor concentration was quantified using tunable diode laser spectroscopy operating in the mid-IR. The HO2 self-reaction rate constant is significantly enhanced by water vapor, consistent with what others have reported, whereas CH3O2 self-reaction and the cross-reaction (CH3O2 + HO2) rate constants are nearly unaffected. The enhancement in the HO2 self-reaction rate coefficient …

Songs Of The Wild: Temporal And Geographical Distinctions In The Acoustic Properties Of The Songs Of The Yellow-Breasted Chat, Jackie L. Canterbury

Department of Animal Science: Dissertations, Theses, and Student Research

The Yellow-breasted Chat, Icteria virens, is a member of the wood-warbler family, Parulidae, and exists as eastern I. v. virens and western I. v. auricollis subspecies. It is the only wood-warbler known to sing diurnally and nocturnally.

One objective was to determine whether the eastern and western subspecies produce songs that differ acoustically; another was to determine whether a western population of Chats in Nebraska produces songs that differ acoustically at dawn and at night. Properties measured were maximum frequency, maximum power, notes/second, singing rate, and % time singing. In addition, the inter-song interval and % whistle notes were measured …

). Size Dependency Of The Elastic Modulus Of Zno Nanowires: Surface Stress Effect, Guofeng Wang, Xiaodong Li

Faculty Publications

Relation between the elastic modulus and the diameter (D) of ZnOnanowires was elucidated using a model with the calculated ZnOsurface stresses as input. We predict for ZnOnanowires due to surface stress effect: (1) when D>20nm, the elastic modulus would be lower than the bulk modulus and decrease with the decreasing diameter, (2) when 20nm>D>2nm, the nanowires with a longer length and a wurtzite crystal structure could be mechanically unstable, and (3) when D<2nm, the elastic modulus would be higher than that of the bulk value and increase with a decrease in nanowire diameter.

The Rate And Timing Of Direct Mountain Front Recharge In An Arid Environment, Silver Island Mountains, Utah, Gregory T. Carling

Theses and Dissertations

Direct mountain front recharge (MFR), water table recharge at the base of the mountain front, was evaluated on the arid (<250 mm/yr precipitation) Silver Island Mountains by comparing mountain precipitation to groundwater response. Direct MFR contributions were assessed on two catchments, one bedrock (i.e., mountain block) dominated and the other alluvial fan (i.e., mountain front) dominated. Catchment precipitation and shallow groundwater levels at each catchment outlet were measured for a 24 month period beginning October 2005. This time period captured one complete hydrologic cycle (December 2005-February 2007) for which annual and seasonal direct MFR rates were calculated. Annual direct MFR was calculated using a modified version of the water table fluctuation (WTF) method as 0.015-0.016% of precipitation on both catchments, with seasonal variations of 0% in summer up to 0.023% in winter, spring and fall. Seasonal direct MFR contributions are similar on the bedrock and the alluvial fan dominated catchments, with a notable exception during fall 2006 when direct MFR was twice as effective on the bedrock dominated system than on the alluvial fan dominated system (0.022% and 0.011% of precipitation, respectively). Darcy's law calculations show similarly low annual direct MFR contributions (0.013-0.032% of precipitation) as those calculated by the WTF method. Calculated direct MFR is 10% or less than typical calculated combined MFR (near surface recharge and deep underflow from the mountain block) for similar terrains and climates, and is only 3.5% of the combined MFR for the Silver Island Mountains as calculated by the Maxey-Eakin model. However, based on total recharge to the adjacent playa, it is apparent that the Maxey-Eakin model overestimates combined MFR, and the small calculated direct MFR is at least 50% of combined MFR. Despite some uncertainty in the numerical results, several patterns are evident in the data. The data show that direct MFR occurs in response to small rainfall events throughout much of the year, and that snowmelt is not necessary to produce direct MFR. The data also show that direct MFR responds more quickly and flushes through the system faster on the alluvial fan catchment than on the bedrock catchment.

Synthesis Of Novel Cysteine Peptide Nucleic Acid (Cpna), Mehul J. Ajmera

USF Tampa Graduate Theses and Dissertations

Many diseases are caused due to abnormalities in production of specific protein. Across this protein the conventional lock and key mechanism shows binding at the specific cites of protein. However use of antisense technology can prevent formation of protein. It does so by binding to mRNA and prevents transcription. The structural modifications lead to synthetic molecules with 18-mer units which show significant improvement in binding properties, this gives birth to a new class of oligomers called Peptide Nucleic Acid (PNA). We herein report cysteine based PNA called CPNA.

Dry Stacked Surface Bonded Masonry - Structural Testing And Evaluation, Eric B. Murray

Theses and Dissertations

The ENDURA block system is a dry-stack surface-bonded masonry system. Typical masonry construction uses thin-set mortar in the bed joints to provide a bearing surface for the blocks while the ENDURA system typically relies on shims and a surface bonding coat to ensure that the wall is level and plumb and to provide stability. Typical ENDURA block walls are built with the reinforcement placed eccentrically in the walls. Testing was performed on ten walls in order to determine axial capacity. The walls were ten feet high by eight feet wide. Each of the walls was built using a different configuration …

One-Dimensional Radial Flow Turbomachinery Performance Modeling, Robert John Pelton

Theses and Dissertations

The Two-Element In Series (TEIS) and Two-Zone models have been used successfully for over twenty years to model test data for radial flow compressors and pumps. The models can also be used to predict the performance of new machines provided that the model inputs can be accurately specified. Unfortunately, use of the TEIS and Two-Zone models as a predictive tool has been limited because an accurate and broadly applicable method of predicting the modeling parameters, etaA, etaB, chi and d2p does not exist. Empirical models have been developed to predict the TEIS and Two-Zone modeling parameters based on a large …

Commercial Critical Systems And Critical Infrastructure Protection: A Future Research Agenda, Matthew J. Warren, Shona Leitch

Australian Information Warfare and Security Conference

Secure management of Australia’s commercial critical infrastructure presents ongoing challenges to owners and the government. Although it is currently managed through high-level information sharing via collaboration, but does this suit the commercial sector. One of the issues facing Australia is that the majority of critical infrastructure resides under the control of the business sector and certain aspects such of the critical infrastructure such as Supply Chain Management (SCM) systems are distributed entities and not a single entity. The paper focuses upon the security issues associated with SCM systems and critical infrastructure protection

Space As A New Sphere Of Future Information Warfare, Martti Lehto

Australian Information Warfare and Security Conference

Air power has seen constant development from the Wright Flyer’s first flight at Kitty Hawk on December 17, 1903 via the advent of the jet age with the service entry of the Messerschmitt Me 262 in 1942, to today’s multirole fighters (F-35 Joint Strike Fighter) and stealth aircraft (B-2 Spirit multi-role bomber). As a result of this evolution of one hundred years air power has emerged as a central component in power projection. As General William Mitchell said: ”Neither armies nor navies can exist unless the air is controlled over them.” (Mitchell 1925, xv)We have witnessed a corresponding development in …

Prevention Of Staphylococcus Epidermidis Biofilm Formation Using A Low-Temperature Processed Silver-Doped Phenyltriethoxysilane Sol–Gel Coating, Niall Stobie, Brendan Duffy, Declan Mccormack, John Colreavy, Martha Hidalgo, Patrick Mchale, Steven Hinder

Articles

Sol–gel coatings which elute bioactive silver ions are presented as a potential solution to the problem of biofilm formation on indwelling surfaces. There is evidence that high-temperature processing of such materials can lead to diffusion of silver away from the coating surface, reducing the amount of available silver. In this study, we report the biofilm inhibition of a Staphylococcus epidermidis biofilm using a low-temperature processed silver-doped phenyltriethoxysilane sol–gel coating. The incorporation of a silver salt into a sol–gel matrix resulted in an initial high release of silver in de-ionised water and physiological buffered saline (PBS), followed by a lower sustained …

Fabrication Of Pillar-Structured Thermal Neutron Detectors, Rebecca J. Nikolić, Adam M. Conway, Catherine E. Reinhardt, Robert T. Graff, Tzu Fang Wang, Nirmalendu Deo, Chin Li Cheung

Barry Chin Li Cheung Publications

Pillar detector is an innovative solid state device structure that leverages advanced semiconductor fabrication technology to produce a device for thermal neutron detection. State-of-the-art thermal neutron detectors have shortcomings in achieving simultaneously high efficiency, low operating voltage while maintaining adequate fieldability performance. By using a 3-dimensional silicon PIN diode pillar array filled with isotopic boron 10, (¹⁰B) a high efficiency device is theoretically possible. The fabricated pillar structures reported in this work are composed of 2 μm diameter silicon pillars with a 4 μm pitch and pillar heights of 6 and 12 μm. The pillar detector with a …
