In this paper we analyse how the behavior of an online financial community in time of geopolitical crises. In particular, we studied the behaviour, composition and communication patterns of online investors before and after a military geopolitical event. We selected a set of 23 key-events belonging to the 2003 US-led invasion of Iraq, the Arab Spring and the first period of the Ukraine crisis. We restricted our study to a set of eight so called military stocks, which are US-manufacturing companies active in the defence sector. We studied the resilience of the community to information shocks by comparing the community …

Underground Structures, Rock Structures And Rock Mechanics From Ancient Era To The Modern Age, Ebru Akiş, Özgür Satici

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Usage of underground space is an old habit for human beings since ancient era. Our ancestors have used caves as a shelter for protection from the wildlife and nature, and they excavated caves to extract valuable minerals. They also used them as sanctuaries, tombs or for storage of goods. In addition, they built tunnels to be used as assault systems or to underpass fortifications during ancient warfare. Later on, tunnels were driven to supply water to the towns or to protect the towns from floods. They also built them for communication purposes. Though not knowing the exact time when they …

Global Command And Control For The Future Operating Concept: Implications For Structural Design And Information, Ian M. Slazinik, Benjamin T. Hazen

Faculty Publications

Due to increasing demands on air mobility aircraft, US Transportation Command(USTRANSCOM) has more recently advocated retaining operational control (OPCON)of aircraft it might have transferred to a requesting combatant command in the past. This recent approach mirrors that of similar-type civilian logistics operations that are centrally managed to maximize efficiencies by flowing resources to the point of need without having to navigate through time-consuming sourcing processes. Furthermore, the acceleration of information availability has condensed decision timelines and changed how similar civilian organizations organize and perform, allowing them to react seemingly on a dime to changing market conditions anywhere.4While retaining OPCON might …

A Sound Idea: An Investigation Into Accessible Video Game Design For The Deaf And Hard Of Hearing, Luke James Brook

Theses: Doctorates and Masters

A widely accepted, and incorrect, assumption towards hearing accessibility in video games is that deaf and hard of hearing (DHH) users are those who encounter the least barriers and are generally well catered for. Rapid advancement in video game technology has seen video game sound evolve from simple blips generated by internal circuitry to fully realised digital audio used to convey critical information. To accommodate the DHH, this information needs to be conveyed in an alternative manner. However, evidence suggests existing accessible design solutions for the DHH lack specificity and are insufficient. Thus, the inability to hear, or hear well, …

Assessing Park-And-Ride Efficiency And User Reactions To Parking Management Strategies, Krae E. Stieffenhofer, Michael Barton, Vikash Gayah V.

Journal of Public Transportation

Increasing the number of spaces at overutilized park-and-rides often is not possible due to budgetary and other constraints. Instead, transit agencies may instead seek to maximize the number of people that are able to use the existing spaces through various parking management strategies. Unfortunately, the efficiency of park-and-rides is difficult to measure, so agencies cannot accurately quantify existing use or improvement after parking management strategies have been applied. This study proposed and tested a method to measure the person-efficiency of park-and-ride lots through an onsite audit. Additionally, a user survey was proposed to confirm the audit results and unveil reactions …

The Influence Of Alkalinity Of Portland Cement On The Absorption Characteristics Of Superabsorbent Polymers (Sap) For Use In Internally Cured Concrete, Juan D. Tabares Tamayo

Open Access Theses

The concrete industry increasingly emphasizes advances in novel materials that promote construction of more resilient infrastructure. Due to its potential to improve concrete durability, internal curing (IC) of concrete by means of superabsorbent polymers (SAP) has been identified as one of the most promising technologies of the 21st century. The addition of superabsorbent polymers into a cementitious system promotes further hydration of cement by providing internal moisture during the hardening and strength development periods, and thus limits self-desiccation, shrinkage, and cracking.

This thesis presents the work performed on the series of cement pastes with varying alkalinity of their pore solutions …

Modeling Methods For Merging Computational And Experimental Aerodynamic Pressure Data, Jacob Courtney Haderlie

Opportunities For Energy-Water Nexus Management In The Middle East & North Africa, Amro M. Farid, William N. Lubega, William W. Hickman

Dartmouth Scholarship

Electric power is required to produce, treat, distribute, and recycle water while water is required to generate and consume electricity. Naturally, this energy-water nexus is most evident in multi-utilities that provide electricity and water but still exists when the nexus has distinct organizations as owners and operators. Therefore, the sustainability question that arises from energy-water trade-offs and synergies is very much tied to the potential for economies of scope. Furthermore, in the Middle East and North Africa (MENA) region, multi-utilities are not only common, but also the nexus is particularly exacerbated by the high energy intensity of the water supply …
