Rotorcraft main rotor noise is therefore, in principle, a function of rotor control inputs, and thus the forces and moments required to achieve steady, or trim, flight equilibrium. In certain flight conditions, the ensuing aerodynamic loading on the rotor(s) can result in highly obtrusive harmonic noise. The effect of the...

Throughout history, states have used different recruitment methods to raise armies. Some of those methods have been successful and some have failed disastrously. This study examines four historical cases to explore underlying patterns that help explain what makes different means of recruitment effective, focusing on the key social factors that are pertinent to raising an army. Using the backdrop of RAND researcher Brian Nichiporuk's competitively multipolar world, this study offers analysis on...

The purpose of this qualitative study is to understand how the century of humiliation plays a role in the formulation of China's overarching grand strategy. Recently, a number of scholars disagree on the extent to and ways in which China is influenced by its history and culture. Gerrit Gong argues that history offers value to what individuals and countries remember and what they forget. From the context of psychological and historical perspectives, this study is anchored using a psychological...

This paper examines the strategic culture of Canada and immerses the reader in the way Canada represents the world surrounding it. Many observers have described Canada as a country which cannot be successfully invaded, nor defended. Maybe in part because of this conundrum, commentators have argued that Canada does not usually get a choice as to how, and when, it employs its military forces. This is an intriguing proposition given that the employment of military forces is usually considered one...

Network knowledge synthesis (NKS) refers to effective use of network defense information for cyber assessment and management. The vision of NKS is to achieve better informed situational awareness leading to superior cyber defense. Five major components are necessary to achieve this vision: sensor placement, data collection, data filtering, data analysis and sense making, and information sharing. By reviewing the state of the art for each of these components, we identify high-priority,...

While nearly 90% of landscape wastes are recovered and processed into soil amendments and organic fertilizers using simple composting technologies, less than 3% of food wastes are recovered and recycled and the remainder are landfilled at considerable cost. Executive Order 13101 calls for the Department of Defense to incorporate waste prevention and recycling into their daily operations. Although most Army installations have effective landscape waste collection and recycling capabilities, they...

Supply chain workers make observable, preventable errors while completing their assigned tasks in the shipping process. Previous research has indicated that individuals with a greater grasp of their work and better system knowledge are less likely to commit interpretation errors. We believe worker-performance may, likewise, be affected by an individuals knowledge of why and where they fit into a larger system defined as mission knowledge. To assess our research objectives, we conduct a...

Active Protection Systems (APSs) are subsystems integrated into or installed on a combat vehicle to automatically acquire, track, and respond with hard or soft kill capabilities to a variety of threats, including rocket-propelled grenades (RPGs) and anti-tank guided missiles (ATGMs). APS technologies are not new, and a number of nations have already employed APS on the battlefield. The U.S. military is now beginning to include APS as part of its formal combat vehicle modernization plans and, if...

This research investigated filamentation in, and modification of, dielectric solids by multi-chromatic ultrashort laser pulses. It was a theoretical effort to develop models of multi-chromatic laser-material interactions in bulk solids and couple these to pulse propagation simulations. The research developed techniques to control filamentation and the onset of laser-induced bulk damage with multi-chromatic pulses. This included controlling modification and filamentation in solids using...

To effectively monitor human performance biomarkers, we applied electrokinetic preconcentration technique of the biomarkers onto patterned graphene-modified\ electrodes in a nanochannel by frequency-selective dielectrophoresis using the molecular dam operation. Low copy numbers of human performance biomarkers can be enriched several orders of magnitudes and detected in tens of seconds. Employing this methodology and electrochemical detection, we have demonstrated the ultrafast and...
