Bytewise Approximate Matching: The Good, The Bad, And The Unknown, Vikram S. Harichandran, Frank Breitinger, Ibrahim Baggili

Journal of Digital Forensics, Security and Law

Hash functions are established and well-known in digital forensics, where they are commonly used for proving integrity and file identification (i.e., hash all files on a seized device and compare the fingerprints against a reference database). However, with respect to the latter operation, an active adversary can easily overcome this approach because traditional hashes are designed to be sensitive to altering an input; output will significantly change if a single bit is flipped. Therefore, researchers developed approximate matching, which is a rather new, less prominent area but was conceived as a more robust counterpart to traditional hashing. Since the conception …

Security Analysis Of Mvhash-B Similarity Hashing, Donghoon Chang, Somitra Sanadhya, Monika Singh

Journal of Digital Forensics, Security and Law

In the era of big data, the volume of digital data is increasing rapidly, causing new challenges for investigators to examine the same in a reasonable amount of time. A major requirement of modern forensic investigation is the ability to perform automatic filtering of correlated data, and thereby reducing and focusing the manual effort of the investigator. Approximate matching is a technique to find “closeness” between two digital artifacts. mvHash-B is a well-known approximate matching scheme used for finding similarity between two digital objects and produces a ‘score of similarity’ on a scale of 0 to 100. However, no security …

The Effect Of Community Connectivity On Water And Sanitation Systems In Rural Panama, M.C. Moritz

Dissertations, Master's Theses and Master's Reports

The world has yet to realize universal access to water and sanitation. Various academic and professional fields provide frameworks for understanding water and sanitation access, but none directly consider the impact of community connectivity. Community connectivity refers to the infrastructures linking rural communities with urban centers. These infrastructures fall under the broad categories of transportation, energy, and telecommunication. This paper examines 23 rural Panamanian communities and compares connectivity measures with the functionality of the communities’ rural water and sanitation systems (RWSS). Community connectivity was evaluated with the Community Connectivity Analysis Tool (CCAT), while the water and sanitation systems were evaluated …

Research Collection College of Integrative Studies

As the world adapts to dual trends of climate change and urbanization, tall office buildings in hot and humid climate zones near the equator are among the prime candidates for a significant change in design approach. Though many individualized improvements to operating systems, envelopes and material selections have been introduced in recent years, it is generally agreed a holistic approach is needed to truly capitalize on the smaller-scale innovations. With a focus on reducing the necessary size of the services plenum, in this paper, an alternative paradigm for the optimization of space, material, and energy use in buildings is presented: …

The Next Billion: Lessons In Off-Grid Electricity Development From The Global South, Peter Mcdonough

Graduate Student Theses, Dissertations, & Professional Papers

Today about a third of the world’s population has no access to electricity, and another third has only limited access. Driven by the push for development on one hand and the reality of climate change on the other, a combination of for-profit companies, NGOs, missions, and aid organizations is looking for the silver bullet to sustainable electricity development. In order to understand the challenges facing off-grid electricity projects I used recent literature in the form of peer-reviewed journals, agency reports, news articles, and technical documents; stakeholder interviews; and on-site observations in selected case studies in Nepal, India, and Tanzania. In …

Energy Sustainability Of Turkey In The Case Of Lng, Omer Ilker Poyraz, Omer Keskin, Resit Unal

Engineering Management & Systems Engineering Faculty Publications

Energy is both vital and strategic element for a nation to sustain its fundamental activities like security, logistics, heating, etc. Countries sustain their energy demands through internal or external sources. In the case of not being able to maintain energy demands from their internal sources, they would need to import their requirements. Whenever they need to buy raw materials, they have to build terminals to process the raw material into the required form. The dependency on the imports may cause the importing country to weaken its advantage in international conflicts, unemployment, and welfare. Therefore, countries aim to mitigate dependence to …

How Do Depression Medications Taken By Pilots Affect Passengers' Willingness To Fly? A Mediation Analysis, Stephen Rice, Scott R. Winter, Keegan Kraemer, Rian Mehta, Korhan Oyman

Publications

The mental health of airline pilots has been a concern for decades. In 2010, the United States Federal Aviation Administration began allowing four types of selective serotonin reuptake inhibitors (SSRIs) to be used by pilots suffering from depression. After a procedural wait period, pilots may be awarded a special issuance of their medical certificates to maintain flight currency. Missing from the literature was any research on consumer’s perceptions of pilots taking antidepressants, along with some other approved medications. Therefore, the purpose of the current study was to examine consumer’s willingness to fly once told that the pilot of their hypothetical …

Consumer Perceptions Towards Package Designs: A Cross Cultural Study, Romica Chandra Lal, Fritz Yambrach, Lucy Mcproud

Journal of Applied Packaging Research

The choice of one package or the other can be an economic decision or can be influenced by cultural acceptance or perception of individual convenience. Product package systems can be designed for one-time use or multiple-use purposes. Package perceptions in different countries typically develop from a variety of factors, including climate, lifestyle, and cultural acceptance with regard to particular products. In an increasingly global economy with multinational firms marketing products worldwide, it is important to understand the differences between consumer needs and consumer responses to product-package systems.

The objective of this research was to examine consumer perceptions of different product …

Sustainable Development For People Or Profit?, Eric Rr Weaver

Suburban Sustainability

As Earth’s populations grow, will key planetary systems be pushed over the “tipping point” beyond Earth’s carrying capacity for sustaining human life? There is a strong body of literature developing the concept of Planetary Boundaries to help identify the limits for maintaining the Earth’s environmental stability. It is presumed that exceeding the Planetary Boundaries will result in an environmental tipping point, shifting the earth into a new environmental equilibrium detrimental to life as we know it. Research shows industrial agriculture is a major force pressing the environment to, and beyond, these limits. This review of top tier journals details the …

Truly tremendous strides have been made in water and food provisioning for humans worldwide. These past two decades have also seen the largest population growth on record, the highest rates of childhood …

Long-Term Functionality Of Rural Water Services In Developing Countries: A System Dynamics Approach To Understanding The Dynamic Interaction Of Causal Factors, Jeffrey P. Walters, Amy N. Javernick-Will

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Research has shown that sustainability of rural water infrastructure in developing countries is largely affected by the dynamic and systemic interactions of technical, social, financial, institutional, and environmental factors that can lead to premature water system failure. This research employs systems dynamic modeling, which uses feedback mechanisms to understand how these factors interact dynamically to influence long-term rural water system functionality. To do this, the research first identified and aggregated key factors from literature, then asked water sector experts to indicate the polarity and strength between factors through Delphi and cross impact survey questionnaires, and finally used system dynamics modeling …

A Game-Theoretic Analysis Of The Nuclear Non-Proliferation Treaty, Peter Revesz

School of Computing: Conference and Workshop Papers

Although nuclear non-proliferation is an almost universal human desire, in practice, the negotiated treaties appear unable to prevent the steady growth of the number of states that have nuclear weapons. We propose a computational model for understanding the complex issues behind nuclear arms negotiations, the motivations of various states to enter a nuclear weapons program and the ways to diffuse crisis situations.

Measuring And Modeling The Effects Of Energy Efficiency And Renewable Energy On Microgrid Operational Performance And Community Welfare In Haiti, Daniel Andrew Krest Schnitzer

Link Foundation Energy Fellowship Reports

While central grid extension often provides electricity at very low cost, the reliability of the central grid in less developed countries is so low that the priority given by policy makers to central grid extension must be questioned. Rather than maximizing the extent of often unreliable or simply unenergized central grid extensions, we sought to show the imperative to consider a multi-track approach to electricity access that includes microgrids and high quality solar lighting products. Through case studies and modeling efforts based on extensive empirical data, this research provides new insight to this imperative and elucidates on the nature of …
