The phrase "are needed for solving" is correct and usable in written English.
It can be used when discussing the requirements or resources necessary to address a problem or complete a task.
Example: "Several key components are needed for solving the complex equation effectively."
Alternatives: "are required for resolving" or "are essential for addressing".
Further studies are needed for solving the contamination issue in the FIB/GIS method and better comparing the two techniques.
Compared to statics, in the context of dynamics we also consider changes that occur over time; hence, situations are more complex and mathematical models which are needed for solving dynamic problems are more complex, too.
Therefore, a code model for the exothermic reaction and hydrogen production, and experimental data are needed for solving the WCLL blanket safety issues associated with the water PbLi interaction.
Only one pipelined triangular linear equation solver is needed for solving Cholesky decomposition and Cholesky decomposition-based linear equation systems.
As a result, on-line solutions applied on an off-line basis show extremely poor results, thus specific research is needed for solving the latter problem.
Particularly, extensive numerical and experimental simulation techniques are needed for understanding and solving the gas entrainment mechanisms and its effects on core safety.
More interestingly, problem posing always precedes problem solving and is an important micro-activity that is needed for problem solving (Pintér 2012).
Because several attempts to find solutions to the problem within the community were not satisfactory, outside specialists were needed for support in solving the problem.
Occasionally, business will admit that government action is needed for businesses to solve problems.
However, the power control problem is formulated in a centralized way such that a CU is needed for the network to solve the optimization problem for all the clusters.
The main purpose of this paper is to investigate the flux limiting approach with high order finite volume method on unstructured meshes which are often needed for solving some important problems on irregular domains.
