Deterring Terroists Organizations In Times Of A Global Pandemic: An Arguement For An Indirect Approach To Deterring Terrorism, Grant Van Robays

Space and Defense

The COVID-19 pandemic has disrupted nearly every facet of life across the world. While the United States is the world's social, economic, and political powerhouse, it is no exception to the indiscriminate virus. The U.S. faces economic volatility, social unrest, political polarization, and a devastating loss of American life due to the pandemic. To make matters worse, these crises leave the U.S. vulnerable to opportunist terrorist organizations at home and abroad, who may seek to take advantage of these vulnerabilities, whether perceived or real. While the pandemic appears to be slowing down both in the U.S. and abroad, the vulnerabilities …

Hypersonic Weapons: Strategic Drivers And Policy Proposals, Jonah S. Bhide

Space and Defense

Whether it is troop movement across terrain, the performance of military aircraft, or the time required responding with national force, speed has always been a critical element in securing U.S. national security objectives. Indeed, Sun Tzu acknowledged that speed is the essence of war, and an essential component in speed is technology. Emerging technologies influence and alter strategic analyses as they are developed and deployed.

Nuclear Planning In An Uncertain World, Brooke Mitchell

Space and Defense

...research is called for on what type of thermonuclear war might eventuate, and on the possible volume of material destruction and loss of human life that might occur in varying hypothetical attack situations.

The 2018 Nuclear Posture Review (NPR) emphasizes a return to great power competition in a world that is no longer preoccupied by violent Islamic fundamentalism in the Middle East and Central Asia. 2 Great power politics are back in style, as the Trump administration made clear. In the post-Cold War era, the United States Department of Defense is focused on modernizing its nuclear enterprise in the face …

Pakistan's Space Program: From Sounding Rockets To Satellite Setbacks, Sannia Abdullah

Space and Defense

Why did Pakistan struggle for 50 years to launch its satellites into Earth's orbit when it was Asia's third country to send sounding rockets into space? Four years ago, India launched 104 satellites from a single rocket to set a groundbreaking record, whereas Pakistan launched only six satellites with assistance in the design, built, launch, and even funding from China. Pakistan plans to send its first astronaut into space by 2022; India put its first astronaut into "space in 1984 as part of a Soviet-led mission." Despite a good head-start, why is Pakistan's space program decades behind when India's space …

Russian Development Of New Hypersonic Weapons: Drivers And Implications, Julia L. Diamond

Space and Defense

The Treaty between the United States of America and the Russian Federation on Measures for the Further Reduction and Limitation of Strategic Offensive Arms (New START) is, at the time of writing, nearing its 5 February, 2021 expiration date. Both the U.S. and Russia have suspended their obligations under the Intermediate-Range Nuclear Forces (INF) Treaty. A renewal of New START would be the most logical future step that aids the cause of arms control. This is the option that requires the least political will and therefore might suit the current political climate. Nevertheless, the political relationship between the two countries …

Mcmaster's Master Work On Geopolitics And The Future Of America: A Review Of Battlegrounds: The Fight To Defend The Free World (Ny: Harpercollins, 2020), Noah Grady

Space and Defense

Student Voice

In his most well-known work, Vom Kriege, Carl von Clausewitz suggested war is a continuation of policy. He proposed governments primarily use warfighting to achieve political ends. Since America's independence in 1776, geopolitics have shaped the nature of America's conflicts overseas. In the last century, the U.S. endured several different geopolitical phases. Despite Woodrow Wilson's reelection slogan, "He kept us out of war," America involved itself in an eruption of imperial interests in Europe during the Great War. Two decades after the First World War, on December 7, 1941, the Japanese Naval Air Service attacked Pearl Harbor. President …

Efficacy Of The National Security Innovation Network's Hacking / Designing For Defense Programs, Max Di Lalla

Space and Defense

Student Voices

The National Security Innovation Network requires further reform to achieve its hope for long-term effects on defense innovation.

The National Security Innovation Network (NSIN) was crated in 2016 after a rebranding of the MD5 National Security Technology Accelerator and is actively changed with the mission to "build networks of innovators that generated new solutions to national security problems." NSIN is just one of the plethora of government organizations tasked with some form of "innovation." As the world begins to change and the United States no longer enjoys a period of unrivaled growth and security, government, military, and private …

Climate Change As A Dangerous Accelerant Of Mass Atrocity, Jesse Jenkins

Space and Defense

Student Voices

Investigating potential connections between mass atrocity and climate change reveals that the vulnerability of food systems may be valuable predictive factor in understanding which states will respond to climate change with violence.

An ongoing study by Dr. John Riley and Lt Col. William Atkins shows that strong states tend to be able to cope well with the effects of climate change and not turn to violence. They also argue that the weakest states are already broken and on the path of committing a mass atrocity regardless of the effects of climate change. This leave a middle section of …

No Method To Madness: The Failures Of Madman Diplomacy In All Its Forms, Henry Gilchrist

Space and Defense

Student Voices

Madman diplomacy fails to work as advertised. Internal contradiction of the strategy in it s ideal form reduce the chances it will succeed in future crises.

Effective deterrence requires an actor to pair powerful capabilities with a believable will to use them. The world of United States' dominance has relegated the question of will to the periphery. However, the U.S. is emerging from its hegemony with enough self-awareness to acknowledge the painful consequences of this relegation. Democratic restraint has historically played an important role in nuclear deterrence for obvious reasons, and the issue of will deficit is not …

Boosting Space Diplomacy At State, David A. Epstein

Space and Defense

Notes from the Field:

Space diplomacy remains an esoteric specialty of State.

With ever-increasing speed, humanity is expanding the scope of its activities in outer space, thanks to private enterprise as well as via national pursuits. In the last two years alone, for example, the number of active and defunct satellites in lower Earth orbit has increase by more than 50 percent, to around 5,000, with plans to add tens of thousands more in the coming years. Equally surprising, these satellites are owned and operated by nearly 100 difference countries and organizations around the world - no just the small …

Future Directions For Great Power Nuclear Arms Control, T. Justin Bronder

Space and Defense

Extending the current New START regime can help maintain traditional strategic stability; however, such an approach fails to address destabilizing trends related to non-nuclear strategic technologies and China's expanding forces.

Arms control in the nuclear age has proved a useful tool of national security, meeting ends as diverse as reducing the risks of nuclear war to channeling strategic competition. Yet recent trends indicate arms control may be at an inflection point; the suitability of this tool in general and the viability of securing new agreements specifically are both unclear. The New Strategic Arms reduction Treaty (New START) extension somewhat reverses …

Rock mechanical parameters have been applied to the fracability evaluation of shales presently, exhibiting great field application performance. Accordingly, it is crucial to obtain accurate rock mechanical parameters. This study developed a physics-informed neural network (PINN) model. Driven by data and physical information, the PINN model can accurately predict rock mechanical parameters using only a small amount of data. To verify its performance, the PINN model was compared with the artificial neural network, random forest, and XGBoost models. The comparison …

Water Inrush Mechanism Of Coal Mine Shaft Fracture Under Fluid-Solid Coupling, Xue Weipei, Shen Lei, Yao Zhishu, Cheng Hua, Rong Chuanxin

Coal Geology & Exploration

The occurrence of coal mine shaft fractures and water inrush accidents is alarmingly frequent, endangering the lives of underground personnel and compromising mine safety. To comprehend the influence of confined groundwater in the process of shaft fracture and the formation mechanism of water inrush channels, a model test was devised using similarity theory and coupled fluid-solid numerical simulation technology. The findings reveal that direct contact between the shaft lining and pressurized water hinders the development of load-bearing and deformation capacities. This is specifically evidenced by the premature appearance of the yield point, a reduction in peak strength and strain, and …

To study the mesoscopic failure characteristics of the layered red shale, uniaxial mechanical experiments were carried out by applying DSTD-1000 electro-hydraulic servo rigid pressure on the red shale with different bedding angles. Meanwhile, SEM and XRD experiments were implemented on debris to obtain its mechanical parameters, failure characteristics, microstructure, and relative content of components. Based on this, models of the red shale with different bedding angles were constructed using the discrete element PFC^3D for the uniaxial compression experiments to study the mesoscopic failure characteristics of red shale. The results show that: (1) When the bedding angle θ=30°, 45°, …

An Attention Mechanism-Based Cnn-Bilstm Real-Time Transient Electromagnetic Method, Gu Yao, Xie Haijun, Zhou Zipeng, Li Lu

Coal Geology & Exploration

The one-dimensional transient electromagnetic (TEM) method is time-consuming and suffers other drawbacks such as difficult parameter adjustment and heavy dependence on the initial model. Therefore, this study proposed a real-time TEM inversion method—the Attention mechanism-based convolutional neural network (CNN) - bidirectional Long Short-Term Memory (BiLSTM) (AC-BiLSTM). By fully utilizing the time difference, the AC-BiLSTM performed model training in non-observation time and the real-time inversion of the collected data in observation time. With the measured data mixed with a certain proportion of data obtained from forward modeling as the dataset, the sampling time and apparent resistivity as the input features in …
