Arms control sceptics claim that arms control is either impossible in hostile rivalries or unnecessary in confrontations where disputes are being resolved. We propose five arms control measures, including training alerts, no travel zones, declaration on principles of training standards, incident notification, and no-testing moratoria in operational deployment areas in South Asia. To test the validity of these five arms control measures, we apply these...

A high-precision calculation method for internal trajectory was proposed for the pneumatic launch system of underwater weapons. The method combined high-precision theoretical derivation with computational fluid mechanics slip technique and used the fourth-order Runge-Kutta method to solve the high-pressure gas domain during the launch process. The sliding grid was used to simulate the single degree of freedom weapon launch in the water area, so as...

The subject matter of this article is the contemporary software solutions used for modeling and visualizing spacecraft missions, specifically during the stages of launch, flight, and landing. The goal of this article is to critically evaluate popular game engines like Unity and Unreal Engine 5, along with specialized flight simulation software such as OpenRocket and Orbiter, focusing on their application in space simulations. The tasks are as follows:...

This study uses a scaled-down model within a proprietary launch tank to address hydrodynamic complexity post-underwater launch. The model addresses the projectile’s motion characteristics and flow field during ejection. This exploration encompassed varying ejection pressures, motion characteristics of the launch platform, initial ejection angles, and depths of ejection. The results show that the projectile’s residual gas appears as filamentous...

In order to solve the problem that the formation and assignment of space launch crew mainly rely on mission experience and lack of theoretical support, firstly, the formation of space launch crew is briefly designed based on the principles of space launch crew allocation, including technical support team, launch team and test team. Secondly, on the basis of the work benefit value of space launch crew in the three teams, the personnel allocation model...

The launch dynamics theory for multibody systems emerges as an innovative and efficacious approach for the study of launch dynamics, capable of addressing the challenges of complex modeling, diminished computational efficiency, and imprecise analyses of system dynamic responses found in the dynamics research of intricate multi-rigid-flexible body systems, such as self-propelled artillery. This advancement aims to enhance the firing accuracy and launch...

Racial preferences, as practiced in academia and elsewhere, by definition, discriminates against individuals based on their race. Radical academics and writers, including the founders of critical race theory, have long supported the use of race as a predominant factor in postsecondary and graduate school admissions. If the Court rules as it should that postsecondary institutions cannot use race as a factor in school admissions, that decision will...

Abstract The Pacific Island Health Officers’ Association, the World Health Organization, and the Pacific Community co-organized the launch of the Pacific Vector Network (PVN) to address challenges posed by mosquito-borne diseases, including dengue fever, Zika virus disease, chikungunya, malaria, and lymphatic filariasis. The PVN was created as a new initiative under the Pacific Public Health Surveillance Network (PPHSN). This launch was a critical...

Abstract Background Preterm delivery continues to be a major concern in the global health system. Where accessible, mother’s milk is the optimal option for neonate nutrition. In recent years, donor milk as the best substitute for mother’s milk where this is not available has become a popular option. The safest method to obtain this milk is from human milk banks. Thus, this study aims to compare the short-term outcomes of preterm neonates pre-...

Due to the difficulty in ensuring launch safety under unfavorable launch site conditions, restrictions regarding the selection of launch sites significantly weaken the maneuverability of the unsupported random vertical launch (URVL) mode. In this paper, a nonlinear robust control strategy is proposed to control the missile attitude by actively adjusting the oscillation of the launcher through the hydraulic actuator, enhancing the launching safety...
