Accidental/Inadvertent Indian Missile Launch and Procedural Arms Control in South Asia

open access: yesJournal for Peace and Nuclear Disarmament
Arms control sceptics claim that arms control is either impossible in hostile rivalries or unnecessary in confrontations where disputes are being resolved.

Synchronized computational architecture for generalized bilateral control of robot arms [PDF]

open access: yes, 1991
A master six degree of freedom Force Reflecting Hand Controller (FRHC) is available at a master site where a received image displays, in essentially real time, a remote robotic manipulator which is being controlled in the corresponding six degree freedom

Comparative Wear and Friction Analysis of Sliding Surface Materials for Hydrostatic Bearing under Oil Supply Failure Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
Hydrostatic bearings excel in high‐precision applications, but their performance hinges on a continuous external supply. This study evaluates various material combinations for sliding surfaces to mitigate damage during supply failures or misalignment and to discover the most effective materials identified for enhancing the reliability and efficiency of

Evaluation of automated decision making methodologies and development of an integrated robotic system simulation: Study results [PDF]

open access: yes
The implementation of a generic computer simulation for manipulator systems (ROBSIM) is described. The program is written in FORTRAN, and allows the user to: (1) Interactively define a manipulator system consisting of multiple arms, load objects, targets,

A new model for gravitational potential perturbations in disks of spiral galaxies. An application to our Galaxy

open access: yes, 2013
We propose a new, more realistic, description of the perturbed gravitational potential of spiral galaxies, with spiral arms having Gaussian-shaped groove profiles.

Development of Aluminum Scandium Alloys for Hydrogen Storage Valves

open access: yesAdvanced Engineering Materials, EarlyView.
Different aluminum alloy series and various aluminum‐scandium alloys with differing Sc and Zr levels are evaluated for use in hydrogen storage valve production. The alloys undergo hardness testing, optical microscopy, and tensile strength analysis, with hardening behavior studied under varying conditions.

Entering 2025: U.S.–Russian relations in the estimates and forecasts of American experts

open access: yesВестник Московского Университета. Серия XXV: Международные отношения и мировая политика
The Biden administration’s policy toward Russia have plunged U.S.–Russian relations into a deep crisis. The bilateral negotiation process on military and political issues, including disarmament and regional conflicts, has been frozen.

Non-strategic nuclear weapons: the next step in multilateral arms control [PDF]

open access: yes
This paper by Crispin Rovere and Kalman A Robertson addresses the many barriers to including tactical nuclear weapons in disarmament talks. It considers the difficulty of bringing other emerging powers such as China into the nuclear arms control equation.

Rebels, Negligent Support, and State Accountability: Holding States Accountable for the Human Rights Violations of Non-State Actors [PDF]

open access: yes, 2013
This Note discusses a crucial problem in the law of state accountability for human rights abuses. Specifically, it analyzes the difficulty of attaching liability when a state negligently supports a group that it should reasonably expect to commit human

Laser Metal Deposited Ti4822 Hollow Pipe: Experimental and Computational Modelling Study

open access: yesAdvanced Engineering Materials, EarlyView.
Laser metal deposition (LMD) of a crack‐free built Ti4822 alloys is challenging. This article reports outstanding characteristics of a hollow pipe that is built with LMD technology when a predicted, nontransformation substrate temperature of 800 °C is used.
