Nineteenth Century North American And Pacific Tidal Data: Lost Or Just Forgotten?, Stefan A. Talke, David A. Jay Nov 2013

Nineteenth Century North American And Pacific Tidal Data: Lost Or Just Forgotten?, Stefan A. Talke, David A. Jay

Civil and Environmental Engineering Faculty Publications and Presentations

Tide data are the oldest and longest oceanographic records and comprise one of the few tools for understanding, quantifying, and separating century-scale human and climate impacts on the coastal zone. Our archival research indicates that continuous measurements of tides began in 1844 in the western Atlantic, 1853 in the Eastern Pacific, and 1858 in the Western Pacific. At least 50 multiyear tide series existed by the year 1900. With few exceptions, however, these 19th and early 20th century measurements have not been analyzed in more than a century and have been forgotten and neglected by the scientific community. This article …

Traditional Boat Building: An Intersection Of Zanzibar’S Culture And Environment, Eric Levenson Oct 2013

Traditional Boat Building: An Intersection Of Zanzibar’S Culture And Environment, Eric Levenson

Independent Study Project (ISP) Collection

This study examined traditional boat building on Uzi Island as a manifestation of Zanzibar’s relationship of environment and culture. Information was gathered about traditional boat building practices, the resource use and management pertaining to boats, the cultural reliance on boats, and local views on environment and conservation. This information showed that the people of Uzi Island were dependent on the use of traditional boats to maintain their livelihood, however the tree types used for boat building are being over-harvested. This tension of culture and environment exposed the need for conservation of Zanzibar’s natural resources in a manner that does not …

Problems And Prospects Of Hydraulic Modelling For Environmental Flows Assessment Studies In East Africa, Preksedis Ndomba Jun 2013

Problems And Prospects Of Hydraulic Modelling For Environmental Flows Assessment Studies In East Africa, Preksedis Ndomba

Tanzania Journal of Engineering and Technology (TJET)

The objective of this paper is to document the problems and prospects of hydraulic modelling for Environmental Flows Assessment (EFA) studies based on selected case studies. Most of studies in East Africa use Holistic methodologies. An ideal data set for defining river hydraulics for most of these methods would be six data points of stage measurements over a good distribution of discharges, the stage of zero discharge and some flood-related data. Besides, in East African region EFA studies suffer from data scarcity (i.e., poorly gauged sites) and limited expertise and funding. The hydraulics studies conducted by the authors entailed desktop …

A Forensic Study Of The Effectiveness Of Selected Anti-Virus Products Against Ssdt Hooking Rootkits, Sami Al-Shaheri, Dale Lindskog, Pavol Zavarsky, Ron Ruhl

Annual ADFSL Conference on Digital Forensics, Security and Law

For Microsoft Windows Operating Systems, both anti-virus products and kernel rootkits often hook the System Service Dispatch Table (SSDT). This research paper investigates the interaction between these two in terms of the SSDT. To investigate these matters, we extracted digital evidence from volatile memory, and studied that evidence using the Volatility framework. Due to the diversity in detection techniques used by the anti-virus products, and the diversity of infection techniques used by rootkits, our investigation produced diverse results, results that helped us to understand several SSDT hooking strategies, and the interaction between the selected anti-virus products and the rootkit samples. …


Significance Of Semantic Reconciliation In Digital Forensics, Nickson M. Karie, H. S. Venter Jun 2013

Significance Of Semantic Reconciliation In Digital Forensics, Nickson M. Karie, H. S. Venter

Annual ADFSL Conference on Digital Forensics, Security and Law

Digital forensics (DF) is a growing field that is gaining popularity among many computer professionals, law enforcement agencies and other stakeholders who must always cooperate in this profession. Unfortunately, this has created an environment replete with semantic disparities within the domain that needs to be resolved and/or eliminated. For the purpose of this study, semantic disparity refers to disagreements about the meaning, interpretation, descriptions and the intended use of the same or related data and terminologies. If semantic disparity is not detected and resolved, it may lead to misunderstandings. Even worse, since the people involved may not be from the …


System-Generated Digital Forensic Evidence In Graphic Design Applications, Enos Mabuto, Hein Venter Jun 2013

System-Generated Digital Forensic Evidence In Graphic Design Applications, Enos Mabuto, Hein Venter

Annual ADFSL Conference on Digital Forensics, Security and Law

Graphic design applications are often used for the editing and design of digital art. The same applications can be used for creating counterfeit documents such as identity documents (IDs), driver’s licences, passports, etc. However, the use of any graphic design application leaves behind traces of digital information that can be used during a digital forensic investigation. Current digital forensic tools examine a system to find digital evidence, but they do not examine a system specifically for the creating of counterfeit documents created through the use of graphic design applications. The paper in hand reviews the system-generated digital forensic evidence gathered …

Relating Air Quality In The Work Environment To Occupational Health Disease, Hussien Awad Alumar May 2013

Relating Air Quality In The Work Environment To Occupational Health Disease, Hussien Awad Alumar

Doctoral Dissertations and Master's Theses

Comprehensive knowledge of the air pollutants effects on the human health generally is a crucial requirement in developing effective policies for reducing such adverse effects related to ambient air pollution. Such knowledge would be essential in helping various affected countries, including the less developed countries (LDCs), to develop effective regulatory frameworks for assessing and managing air quality in the workplaces. Developed and developing countries therefore need to develop effective techniques or strategies focused towards improving the workplace monitoring competence in diverse industrial environments. Such initiatives are essential in reducing or eliminating the industrial pollutants within the workplaces while also helping …


Soil Organic Carbon Dynamics In Agriculture: Model Development And Application From Daily To Decadal Timescales, Matthew P. Pelton May 2013

Soil Organic Carbon Dynamics In Agriculture: Model Development And Application From Daily To Decadal Timescales, Matthew P. Pelton

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Soil carbon (C) is the largest terrestrial C pool globally, containing more C than the atmosphere and biosphere. Soil organic carbon (SOC) is a source and sink of CO2 emissions to and from the atmosphere, thus influencing future climate change. Understanding SOC dynamics is also important for maintaining C stocks to sustain and improve crop yields. An existing model to estimate changes in SOC due to respiration was modified to operate in three computational platforms: MS Excel, MS Excel with Visual Basic for Applications, and supercomputing. This model was validated against CO2 flux data from a 9-year field …

Ocean Current Measurements: Challenges And Opportunities In The Florida Current, William E. Baxley Mar 2013

Ocean Current Measurements: Challenges And Opportunities In The Florida Current, William E. Baxley

HCNSO Student Capstones

The water velocities offshore south Florida are dominated by the Florida Current, and these effects result not only from the tremendous flow of water between Florida and the Bahamas, but also from the eddies and other rotational components imparted by the change in flow direction from eastward to northward along the Florida Keys and the end of the peninsula. These currents have been measured for decades, with methods ranging from subsurface floats to acoustic Doppler current profilers (ADCPs) and surface current measuring radars. Data suggests that there is a large degree of variability in the mean flow, including significant vorticity …


Csp Desalination/Water Purification Unit, Sean Goodison Mar 2013

Csp Desalination/Water Purification Unit, Sean Goodison

Industrial Technology and Packaging

An estimated 3.4 million people die each year from unsanitary water or inaccessible water supply. Most of these deaths take place in the developing, third world (99%). There is a dilemma arising on the world stage as well. The water demand/supply deficit is expected to increase significantly over the next 37 years if preemptive action isn’t taken. 97% of the world water supply is oceanic, making it an attractive solution to the water deficit. Providing autonomous, “deploy and watch” systems for utilizing sustainable energy to provide purified water for unitized low pricing has the potential to penetrate a large world …

Effects Of Molecular Structure Of The Oxidation Products Of Reactive Atmospheric Hydrocarbons On The Formation Of Secondary Organic Particulate Matter, Including The Effects Of Water, Negar Niakan Jan 2013

Effects Of Molecular Structure Of The Oxidation Products Of Reactive Atmospheric Hydrocarbons On The Formation Of Secondary Organic Particulate Matter, Including The Effects Of Water, Negar Niakan

Dissertations and Theses

Organic aerosols have significant effects on human health, air quality and climate. Secondary organic aerosols (SOA) are produced by the oxidation of primary-volatile organic compounds (VOC). For example, α-pinene reacts with oxidants such as hydroxyl radical (OH), ozone (O3), and nitrate radical (NO3), accounting for a significant portion of total organic aerosol in the atmosphere. Experimental studies have shown that the oxidation process between α-pinene and ozone has the most significant impact in the formation of SOA (Hoffmann et al., 1997). Most of the models used to predict SOA formation, however, are limited in that they …

Tackling Change: Future-Proofing Water, Agriculture, And Food Security In An Era Of Climate Uncertainty, Peter G. Mccornick, Vladimir Smakhtin, Luna Bharati, Robyn Johnston, Matthew Mccartney, Fraser Sugden, Floriane Clement, Beverly Mcintyre

Daugherty Water for Food Global Institute: Faculty Publications

In 1950 the global population was just over 2.5 billion. Now, in 2013, it is around 7 billion. Although population growth is slowing, the world is projected to have around 9.6 billion inhabitants by 2050. Most of the population increase will be in developing countries where food is often scarce, and land and water are under pressure. To feed the global population in 2050 the world will have to produce more food without significantly expanding the area of cultivated land and, because of competition between a greater number of water users, with less freshwater. On top of land and water …

Green Diesel Production Via Catalytic Hydrogenation/Decarboxylation Of Triglycerides And Fatty Acids Of Vegetable Oil And Brown Grease, Elvan Sari Jan 2013

Green Diesel Production Via Catalytic Hydrogenation/Decarboxylation Of Triglycerides And Fatty Acids Of Vegetable Oil And Brown Grease, Elvan Sari

Wayne State University Dissertations

Increase in the petroleum prices, projected increases in the world’s energy demand and environmental awareness have shifted the research interest to the alternative fuel technologies. In particular, green diesel, vegetable oil/animal fat/waste oil and grease derived hydrocarbons in diesel boiling range, has become an attractive alternative to biodiesel— a mixture of fatty acid methyl esters, particularly due to its superior fuel properties that are similar to petroleum diesel. Hence, green diesel can be used as a drop-in fuel in the current diesel engines. The current technology for production of green diesel– hydrodeoxygenation of triglycerides and fatty acids over conventional hydrotreating …
