A numbers of the series of types of cross-sections of bars t is also taken as a criterion of optimization. The sets of non-dominated (efficient) and compromise (Pareto optimal) solutions and the preferable solution for space truss are found. The results are presented in the form of ...
design problems. 2. Truss design Truss optimization is typically focused on finding a design that minimizes the structural weight while satisfying stress and dis- placement constraints. When the truss geometry is fixed, the objective of the optimization is to select a cross-sectional area ...
1 For spacecraft operating in orbit, they often face problems such as high maintenance costs, aging equipment functions, and limited fuel life.2 How to ensure a more durable and stable orbital operation of spacecraft in a complex space environment at a lower cost, and achieve the goal of a...

This component can find out solutions to approximate the true PF under the convergence assumption. In cases where MOSG problems are too complex for this assumption, the refinement component steps in to enhance solution convergence. The number of attackers and targets are significant dimensions that ...
However, these problems are often balanced by the ease of moving heavy objects, the use of three-dimensional space, and the sheer pleasure of floating in a weightless environment. Why Artificial Gravity? Space biomedical researchers have been working for many years to develop "countermeasures" to ...
For future high-power space nuclear reactors, the advantages of using highly enriched uranium to reduce volume and weight will gradually diminish due to thermal problems. Consequently, there will be a shift towards utilizing low enriched uranium for nuclear fuel. In addition, the fission gas in ...
This boom is a deployable, periodic trussed structure, which deploys from a nanosat form factor, such as a CubeSat. The boom itself is made of an array of battens and diagonal members that deploy via the tape spring longerons that are rolled up in the base of the structure. Inside ...
At the turn of the twenty-first century, fundamental changes took place in the understanding of the structure and function of proteins and then in the appr
