Construction And Transformation Technology Of Three-Dimensional Fine Model Of Mine Water Diversion Structure, Fan Juan, Hou Enke, Jin Dewu, Qiao Wei, Nan Shenghui

Coal Geology & Exploration

The development degree of natural fractures is the main factor affecting coalbed methane productivity. In order to accurately obtain the distribution position of the natural fractures in the a coalbed methane field in the southern Qinshui basin, 7 refracturing wells in the area were adopted by surface microseismic vector scanning to monitor the natural fractures. A certain amount of three-component geophones were deployed around the fracturing well to collect microseismic events in the surrounding reservoir during fracturing, and after Semblance superposition, the fracture energy slices at different times in the monitoring area were obtained to explain the natural fractures in …

Study On Underwater Navigation For Underwater Track Vehicle, Dae-Hyeong Ji, Hyeung-Sik Choi, Sang-Ki Jeong, Hyun-Joon Cho, Ji-Hyeong Lee, Wen-Hsiang Hsieh

Journal of Marine Science and Technology–Taiwan

In this study, an underwater navigation algorithm was developed to apply a navigation system to an underwater track vehicle (UTV). Generally, a Doppler velocity log (DVL) is used to obtain the velocity information of underwater vehicles. However, a DVL cannot be used in a UTV owing to vehicle vibration and limited sensing distance. Hence, dead reckoning navigation is typically used, which results in severe errors in altitude and position values over long periods of operation. To address these problems, in this study, we developed a new underwater navigation system for a UTV using navigation sensors comprising an inertial navigation system, …

A Study On The Analysis Of Minimum Speed Control Effect Using Queue Model Focused On Busan Port, Sangwon Park, Won-Sik Kang, Young-Soo Park

Journal of Marine Science and Technology–Taiwan

VTS aims to increase the efficiency of maritime traffic in two ways.

Evolution Of Magnetic-Field-Induced Ordering In The Layered Structure Quantum Heisenberg Triangular-Lattice Antiferromagnet Ba3Cosb2O9, Nathanael Alexander Fortune, Q. Huang, T. Hong, J. Ma, E. S. Choi, S. T. Hannahs, Z. Y. Zhao, X. F. Sun, Y. Takano, H. D. Zhou

Physics: Faculty Publications

Quantum fluctuations in the effective spin-1/2 layered structure triangular-lattice quantum Heisenberg antiferromagnet Ba₃CoSb₂O₉ lift the classical degeneracy of the antiferromagnetic ground state in magnetic field, producing a series of novel spin structures for magnetic fields applied within the crystallographic ab plane, including a celebrated collinear ‘up-up-down’ spin ordering with magnetization equal to 1/3 of the saturation magnetization over an extended field range. Theoretically unresolved, however, are the effects of interlayer antferromagnetic coupling and transverse magnetic fields on the ground states of this system. Additional magnetic-field-induced phase transitions are theoretically expected and in some cases have …

We Are All Gig Workers Now: Online Platforms, Freelancers & The Battles Over Employment Status & Rights During The Covid-19 Pandemic, Orly Lobel

San Diego Law Review

Since the early days of the Coronavirus pandemic, unemployment rates leapt to the highest they have been since 1975. Congress passed the Coronavirus Aid, Relief, and Economic Security (CARES) Act in March 2020, a $2 trillion relief package, offering augmented unemployment relief not only to employees but also to the self-employed, including gig workers. The Families First Coronavirus Response Act (FFCRA) was passed to provide sick leave in the form of tax credits that also extended to the self-employed. Beyond the governmental responses, platform companies offered new limited relief to their workers in the form of sick leave, even as …

Covid-19 And Preventing Harm To Vulnerable Children, Jessica K. Heldman, Margaret A. Dalton, Robert C. Fellmeth

San Diego Law Review

Although COVID-19 mercifully seems to affect children less severely than adults, children are far from immune from the impacts of the virus. Public health orders closing schools and businesses, cancelling events, and keeping children at home have been disruptive and distressing to many children and families. But for children who rely on government entities for protection, care, custody, and services, the effects of the public health orders can be devastating. COVID-19 and the response to it has serious implications for the safety, well-being, and development of these vulnerable children—those within the child welfare, juvenile justice, and special education systems. All …

The Covid Cases: A Preliminary Assessment Of Judicial Review Of Public Health Powers During A Partisan And Polarized Pandemic, Wendy E. Parmet

San Diego Law Review

In response to the very real possibility that there will be insufficient resources to properly respond to the COVID-19 pandemic, states have been developing crisis standard of care plans, which may authorize the prioritization of patients for scarce resources based on changing circumstances and increased demands. Due to the dearth of necessary resources and trained professionals during a public health emergency, the standard of care that clinicians may be able to provide during the COVID-19 pandemic may, by necessity, depart significantly from standard nonemergency medical practice. Adhering to crisis standards of care may expose health care providers and entities to …

Prisons And Pandemics, Camila Strassle, Benjamin E. Berkman

San Diego Law Review

This Article focuses on how to balance public health, public safety, and incarcerated people’s legal rights when implementing a program for early release from confinement. Ethical, epidemiological, and legal arguments all point to a need for an immediate reduction in the incarcerated population. However, this leaves open several points of reasonable disagreement about how to manage early release. These include how to set priorities for processing and releasing individuals across the country. For example, officials could prioritize screening individuals who are housed in facilities that have been hit hard by infection; or by screening individuals who have a safe place …
