Resilient engineered systems: the development of an inherent system property

Mitchell, Susan McAlpin 17 September 2007 (has links)
Protecting modern engineered systems has become increasingly difficult due to their complexity and the difficulty of predicting potential failures. With the added threat of terrorism, the desire to design systems resilient to potential faults has increased. The concept of a resilient system – one that can withstand unanticipated failures without disastrous consequences – provides promise for designing safer systems. Resilience has been recognized in research settings as a desired end product of specific systems, but resilience as a general, inherent, measurable property of systems had yet to be established. To achieve this goal, system resilience was related to an established concept, the resiliency of a material. System resilience was defined as the amount of energy a system can store before reaching a point of instability. The energy input into each system as well as the system’s exergy were used to develop system stress and system strain variables. Process variable changes to four test systems – a steam pipe, a water pipe, a water pump, and a heat exchanger – were applied to obtain series of system stress and system strain data that were then graphed to form characteristic system response curves. Resilience was quantified by performing power-law regression on each curve to determine the variable ranges where the regression line accurately described the data and where the data began to deviate from that power-law trend. Finally, the four test systems were analyzed in depth by combining them into an overall system using the process simulator ASPEN. The ranges predicted by the overall system data were compared to the ranges predicted for the individual equipment. Finally, future work opportunities were outlined to show potential areas for expansion of the methodology.

Directionally Sensitive Neutron Detector For Homeland Security Applications

Spence, Grant 2011 December 1900 (has links)
With an increase in the capabilities and sophistication of terrorist networks worldwide comes a corresponding increase in the probability of a radiological or nuclear device being detonated within the borders of the United States. One method to decrease the risk associated with this threat is to interdict the material during transport into the US. Current RPMS have limitations in their ability to detect shielded nuclear materials. It was proposed that directionally sensitive neutron detectors might be able to overcome many of these limitations. This thesis presents a method to create a directionally sensitive neutron detector using a unique characteristic of 10B. This characteristic is the Doppler broadening of the de-excitation gamma-ray from the 10B(n, alpha) reaction. Using conservation principles and the method of cone superposition, the mathematics for determining the incoming neutron direction vector from counts in a boron loaded cloud chamber and boron loaded semiconductor were derived. An external routine for MCNPX was developed to calculate the Doppler broaden de-excitation gamma-rays. The calculated spectrum of Doppler broadened de-excitation gamma-rays was then compared to measured and analytical spectrums and matched with a high degree of accuracy. MCNPX simulations were performed for both a prototype 10B loaded cloud chamber and prototype 10B loaded semiconductor detector. These simulations assessed the detectors' abilities to determine incoming neutron direction vectors using simulated particle reactant data. A sensitivity analysis was also performed by modifying the energy and direction vector of the simulated output data for 7Li* particles. Deviation coefficients showed a respective angular uncertainty of 1.86 degrees and 6.07 degrees for the boron loaded cloud chamber and a boron loaded semiconductor detectors. These capabilities were used to propose a possible RPM design that could be implemented.

Vlastivědný atlas České republiky / Atlas of the Czech Republic for primary school

Břichňáčová, Eliška January 2012 (has links)
Diploma thesis deals with proposal conception prepare homeland book of maps Czech republic. Book of maps will determined for pupils 1. – 2. class primary school and serve at teaching hours of elementary technig. Pupils should get basic information about Czech republic and her continuity on Europe and world with this school tool. The first part of the thesis deals with the theoretical process of cartographic work. Part two describes the her practical execution. At the end of atlas functionality was verified among children at an primary school in Běrunice.

Regional Readiness For Intelligence Information Sharing To Support Homeland Security

Kemp, Christine Genet 01 January 2005 (has links)
The Markle Task Force on National Security in the Information Age was created to produce recommendations on how to best leverage intelligence and information to improve security without compromising existing civil liberties. Their second report proposed that the government set up an information-sharing network using currently available technology to improve our ability to prevent terrorist attacks, while protecting civil liberties. The Markle recommendations have been incorporated into the recent Intelligence Reform and Terrorism Prevention Act of 2004. The proposition is that the Markle task force recommendations are sufficient to achieve the required data integration in the United States. To affirm or falsify the proposition, three existing systems will be reviewed: Alabama's Law Enforcement Tactical System Portal (LETS), Florida's Statewide Data Sharing Effort (FINDER), and Orange County, Florida's Integrated Criminal Justice System. This study found that there is no overall model for national intelligence analysis that incorporates the capabilities that law enforcement has for collection and analysis in with the federal capabilities for collection and analysis. This may ultimately limit the regional systems' success. Recommendations for potential initial models are made. In addition, recommendations for improvement in each regional system are provided. Finally, further research is needed to refine a national intelligence analysis model that can be supported by a distributed information sharing network.

Ett komplext hemland : En kvalitativ studie av televisionsprogrammet Homeland / A homeland of complexity : A qualitative study of the television series Homeland

Andersson, Alexandra January 2013 (has links)
After 9/11 and the following War on Terror, Muslims are often understood as global enemies. However, the idea of an international, Islamic enemy is in some circumstances criticized, not least after the actions of Anders Behring Breivik in Norway in 2011. This study analyses the North American, Emmy Award-winning television series Homeland. It centres on the War on Terror and the following social and political climate, and there are opposing understandings regarding how religion and ethnicity are portrayed in the series. Accordingly, the aim of this study is to analyse how such aspects are constructed in the series. A text analysis is used methodologically and the theoretical perspective contents of Semiotics, Eurocentrism and Orientalism in general, and Islamophobic themes in particular. This study shows that in Homeland, the portrayal of heroes and enemies plus good and evil is complex. Islamophobic ideas are present, however, instead of agreeing with them, these often times show how such ideas are part of today's society and how they are affecting Western ideas of Muslims as public enemies. Concurrently, Christianity is exclusively portrayed in civilized circumstances, whereas Islam occasionally is portrayed asa sort of being that controls its adherents. With that said, Homeland is above all a construction of complexity.
